The glenohumeral joint has a greater range of motion than any other joint in the body. WebIt typically takes from 9 to 12 months for an acetabular fracture to completely heal. There are many labral variants. Skeletal trauma, basic science, management, and reconstruction. These fractures occur when a varus force is applied to the extended elbow. Musculoskeletal eponyms: who are those guys? Once you realize that, it should not confuse you. The anterosuperior labrum is absent in the 1-3 o'clock position and the middle glenohumeral ligament is usually thickened. 2009; 38(10):967-975. by Herold T, Bachthaler M, Hamer OW, et al. Clavicular fractures are common and account for ~5% (range 2.6-10%) of all fractures 2,3. Musculoskeletal eponyms: who are those guys? The fractures involve the medial malleolus, the posterior aspect of the tibial plafond (referred to as the posterior malleolus) and the lateral malleolus. Closed / Simple: A fracture is considered to be clinically healed based upon the combination of physical findings and symptoms over time. Typical mechanism: punching (most common) fall One of the spinous processes is in two pieces and the two pieces are widely separated. Males are affected more commonly than females with a median age of injury of 56 years. This guideline covers assessing and managing pelvic fractures, open fractures and severe ankle fractures (known as pilon fractures and intra-articular distal tibia fractures) in pre-hospital settings (including ambulance services), emergency departments and major trauma centres. There is a spinous process fracture, which is not a key element but a frequently associated injury. It is very common to see more fractures on imaging with CT and MRI than on the radiographs. It is either loss of height of the anterior part of the vertebral body or disruption of the vertebral endplate. Gustilo Anderson classification (compound fracture), Anderson and Montesano classification of occipital condyle fractures, Traynelis classification of atlanto-occipital dissociation, longitudinal versus transverse petrous temporal bone fracture, naso-orbitoethmoid (NOE) complex fracture, cervical spine fracture classification systems, AO classification of upper cervical injuries, subaxial cervical spine injury classification (SLIC), thoracolumbar spinal fracture classification systems, AO classification of thoracolumbar injuries, thoracolumbar injury classification and severity score (TLICS), Rockwood classification (acromioclavicular joint injury), Neer classification (proximal humeral fracture), AO classification (proximal humeral fracture), AO/OTA classification of distal humeral fractures, Milch classification (lateral humeral condyle fracture), Weiss classification (lateral humeral condyle fracture), Bado classification of Monteggia fracture-dislocations (radius-ulna), Mason classification (radial head fracture), Frykman classification (distal radial fracture), Hintermann classification (gamekeeper's thumb), Eaton classification (volar plate avulsion injury), Keifhaber-Stern classification (volar plate avulsion injury), Judet and Letournel classification (acetabular fracture), Harris classification (acetebular fracture), Young and Burgess classification of pelvic ring fractures, Pipkin classification (femoral head fracture), American Academy of Orthopedic Surgeons classification (periprosthetic hip fracture), Cooke and Newman classification (periprosthetic hip fracture), Johansson classification (periprosthetic hip fracture), Vancouver classification (periprosthetic hip fracture), Winquist classification (femoral shaft fracture), Schatzker classification (tibial plateau fracture), AO classification of distal femur fractures, Lauge-Hansen classification (ankle injury), Danis-Weber classification (ankle fracture), Berndt and Harty classification (osteochondral lesions of the talus), Sanders CT classification (calcaneal fracture), Hawkins classification (talar neck fracture), anterior superior iliac spine (ASIS) avulsion, anterior cruciate ligament avulsion fracture, posterior cruciate ligament avulsion fracture, avulsion fracture of the proximal 5th metatarsal, measuring the size of the fracture fragment as a percentage of the total articular surface on the lateral radiograph or sagittal CT is useful as this is one of the indications for internal fixation (although operative threshold is variable), articular steps >1 mm are also an indication for internal fixation. 9. There is widening between the spinous processes. Look for variants like the Buford complex. A simple compression fracture is the most common form of injury and is seen in 90% of cases. Radiology. Analogous to the 3-column classification of Denis, some investigators consider the sternum as the fourth column in upper thoracic spinal fractures and recognize it as an independent variable in the assessment and treatment of these patients (5). They all attach to the greater tuberosity. But look at the spinous processes. 7. Reference article, Radiopaedia.org (Accessed on 11 Dec 2022) https://doi.org/10.53347/rID-2283, {"containerId":"expandableQuestionsContainer","displayRelatedArticles":true,"displayNextQuestion":true,"displaySkipQuestion":true,"articleId":2283,"questionManager":null,"mcqUrl":"https://radiopaedia.org/articles/weber-classification-of-ankle-fractures/questions/2549?lang=us"}. When the PLC is definitely injured on CT, it can already be scored as 3. At this level also look for Bankart lesions. In the Denis classification a burst fracture is classified as a two-column injury, calling it unstable and requiring surgical stabilization. ADVERTISEMENT: Supporters see fewer/no ads. Having three parts, this is a more unstable fracture and may be associated with ligamentous injury. Skinner HB. J Fam Pract. 1. 2018;3(6):374-80. When there are several fractures, each level has to be scored separately. MR is the best imaging modality to examen patients with shoulder pain and instability. The outcomes of treatment will vary from patient to patient, depending on the following: Pattern and severity of the fracture; Other injuries associated with the trauma Patient's age and bone quality; Patient's general health, including smoking status. 2. In severe pelvic fracture patients, 60.6% received transfusion, with a mean of more than 3.5 L. When severe pelvic injury was the only significant injury, more than 50% received transfusion, with a mean of 2.7 L. Overall, 16.6% of pelvic fracture patients required more than 2 L of blood in transfusion. Wolters Kluwer 2014. Mohammed R, Syed S, Metikala S et-al.

PLC: very subtle widening of right facet joint - 2 or 3 points, PLC: always disrupted in translation - 3 points, PLC: always disrupted in distraction on posterior side - 3 points, PLC: widening of both facet joints (yellow arrow) and a fracture of spinous process (blue arrow) - 3 points, PLC: always torn in posterior distraction - 3 points. One of the fractures is a typical avulsion. Current diagnosis & treatment in orthopedics. Large tears of the rotator cuff may allow the humeral head to migrate upwards resulting in a high riding humeral head. posterior element. Fractures of the ankle joint: investigation and treatment options. Torus fractures,also known as buckle fractures, are incomplete fractures of the shaft of a long bone that is characterized by bulging of the cortex. 20 (3): 819-36. Radiology 2005;236:601, by Bharti Khurana WebFracture compression increases the contact area across the fracture and increases stability of the fracture. WebInjury was founded in 1969 and is an international journal dealing with all aspects of trauma care and accident surgery.Our primary aim is to facilitate the exchange of ideas, techniques and information among all members of the trauma team.

Jeray KJ. Strictly speaking, a torus fracture refers to a circumferential buckle fracture 7. Hill Sachs lesions are only seen at the level of the coracoid. That is until we zoom in and look at the distance between the spinous processes. These normal variants will usually not mimick a Bankart-lesion, since it is located at the 3-6 o'clock position, where these normal variants do not occur. 4. The axial CT and MRI in the same patient show the displaced fragment pressing on the thecal sac. They are self-limiting and typically do not require operative intervention, although a manipulation may be required if the angulation is severe. Rarely, a torus fracture may refer to the fracture of an oral torus, and there is potential for the two terms to be confused 10. So we should call this a translation fracture with anterior displacement. Radiographics. WebDue to poor osseous congruency and capsular laxity, the glenohumeral joint is very unstable, which makes it the most frequently dislocated joint in the human body. Gardne MJ, Siegel JA. 3. TLICS also facilitates appropriate treatment recommendations. CT is the best modality for identifying an occipital condyle fracture 6. A distraction injury on the posterior side can lead to a compression fracture on the anterior side. W B Saunders Co. (2003) ISBN:0721691757. However, the vast majority (~75%; range 69-85%) occur in the midshaft, at or near the junction of the middle and outer third with distal clavicle fractures (15-20%) and medial clavicle fractures (<5%) less common 3,8. It is important to note that occult fractures may be present in the apparently normal radiograph; this is relatively common in children and also occasionally seen in adults 2. Look for impingement by the AC-joint. ADVERTISEMENT: Radiopaedia is free thanks to our supporters and advertisers. Full Text Association Between Hemorrhage Control Interventions and Mortality in US Trauma Patients With Hemodynamically Unstable Pelvic Fractures 30, 2022. The sagittal reformatted image also shows the cortical disruption. This is an interesting case since non-surgical management was initially attempted in this patient. Fractures through the posterior elements (red arrows). Sambandam B, Gupta R, Kumar S, Maini L. Fracture of distal end clavicle: A review. 2003;10 (2): 71-5. Bone marrow edema in several vertebral bodies, either due to contusion or fracture. {"url":"/signup-modal-props.json?lang=us\u0026email="}, Datir A, Ramsey, MD A, Lustosa L, et al. 5 (2): 65-73. Radiologic history exhibit. Now when you describe such a fracture the first word in your report should be distraction, i.e. Given the spectrum of injury that occurs with flexion teardrop fracture, it is less important to label the findings as "flexion teardrop" and more important to draw attention to clinically relevant information. Fractures can occur at any part of the clavicle. 7. Full Text Association Between Hemorrhage Control Interventions and Mortality in US Trauma Patients With Hemodynamically Unstable Pelvic Fractures 30, 2022. The abduction and external rotation of the arm releases tension on the cuff relative to the normal coronal view obtained with the arm in adduction. However the CT shows a thin fracture line through the anterior side of the vertebral body and also through the spinous process. burst (2 points). In this case we are not sure. Due to the tension by the anterior band of the inferior GHL labral teras will be easier to detect. Posterolateral corner injury is thought to account for approximately 16% of acute injuries of the knee 4,5.It is often seen in sports-related injuries and mostly related to direct anteromedial tibial impact trauma, but is also caused by hyperextension and external rotation injuries, non-contact varus stress injuries, and Fractures of the ankle joint: investigation and treatment options. Practical points. As long as there is no free fragment with posterior displacement, it is a wedge compression fracture and not a burst fracture. Furthermore, the word stability itself is ambiguous and may refer to direct osseous stability; it may refer to neurological stability and finally, to long-term (ligamentous) stability. At first glance the AP-view doesn't look very odd. 5. Bipolar clavicular fractures occur when there are both distal and medial clavicular injuries, most commonly a distal clavicle fracture in combination with an anterior sternoclavicular joint dislocation 8. Epidemiology. Notice that the supraspinatus tendon is parallel to the axis of the muscle. Study the attachment of the IGHL at the humerus. (2020) RadioGraphics. 1997;79 (4): 537-9. 3. Emerg Med J. The TLICS consists of three independent parameters: A parameter can be scored 0-4 points and the total score is the sum of these parameters with a maximum of 10 points. ORTHOPEDICS August 2010;33(8):562. by Schreinemachers SA, van der Hulst VP, Willems WJ, Bipat S, van der Woude HJ.

They tend to be unstable and become displaced because of the pull of the forearm extensors. 2015;111 (21): 377-88. fractures involving a single facial buttress, Meyers and McKeevers classification (anterior cruciate ligament avulsion fracture), Watson-Jones classification (tibial tuberosity avulsion fracture), Nunley-Vertullo classification (Lisfranc injury), pelvis and lower limb fractures by region. The supraspinatus tendon is the most important structure of the rotator cuff and subject to tendinopathy and tears. When you plan the coronal oblique series, it is best to focus on the axis of the supraspinatus tendon. You can see the edema related to the fracture of the vertebral body and the massive edema in the paraspinous muscles. It was later modified and popularized by the Swiss orthopedic surgeon,Bernhard Georg Weber (1929-2002),in 1972 2. nor be effaced against the humeral head, and intra-articular contrast can enhance visualization of the tear (3). Galeazzi fracture-dislocations are unstable requiring surgical intervention, which involves open reduction and internal fixation (ORIF) of the radial fracture, intraoperative assessment of the distal radioulnar joint for reducibility and stability, and subsequent Kirschner wire fixation of the ulna to the radius, triangular Rarely, a torus fracture may refer to the fracture of an oral torus, and there is potential for the two terms to be confused 10. Discussion: based on only these two images it is hard to say whether this is burst with PLC-injury or maybe distraction on the posterior side. 2016;8(4):367-72. fractures involving a single facial buttress, Meyers and McKeevers classification (anterior cruciate ligament avulsion fracture), Watson-Jones classification (tibial tuberosity avulsion fracture), Nunley-Vertullo classification (Lisfranc injury), pelvis and lower limb fractures by region. In the absence of a neurologic deficit, PLC integrity should be confirmed at MR imaging, especially if conservative management of a burst fracture is planned (3). Prop 30 is supported by a coalition including CalFire Firefighters, the American Lung Association, environmental organizations, electrical workers and businesses that want to improve Californias air quality by fighting and preventing wildfires and reducing air pollution from vehicles. The Spine Journal, the official journal of the North American Spine Society, is an international and multidisciplinary journal that publishes original, peer-reviewed articles on research and treatment related to the spine and spine care, including basic science and clinical investigations.. fracture may arise as proximally as the level of fibular neck and not visualized on ankle films, requiring knee or full-length tibia-fibula radiographs (Maisonneuve fracture) unstable: usually requires ORIF; Weber C fractures can be further subclassified as 6. ISRN Rheumatology The TLICS-score is high, because there is distraction and injury to the PLC. This sublabral recess can be difficult to distinguish from a SLAP-tear or a sublabral foramen. What are the findings? At first glance this looks just like another burst fracture. Trimalleolar fractures refer to a three-part fracture of the ankle. They result from trabecular compression due to an axial loading force along the long axis of the bone. Rotator cuff tears Pathology. 4. In type III there is a large sublabral recess. TLICS score based on imaging is 7 points. 2. hook of hamate fracture; Clinical presentation. 6. The main feature is posterior distraction with horizontal fractures of posterior elements (red arrow), Avulsion of a spinous process (yellow arrow), The morphology is of a vertebral fracture with retropulsion of a fragment, i.e. An Sist Sanit Navar. Retropulsion of a body fragment and the percentage of narrowing of the spinal canal. 8. Usually the morphology matches the injury mechanism, but sometimes it does not. McGraw-Hill Medical. Cervical spine fractures can occur secondary to exaggerated flexion or extension, or because of direct trauma or axial loading.. In addition to reporting the presence of the fracture a number of features should be sought and in many instances commented upon as relevant negatives: J Orthop Traumatol. Mainwaring BL, Daffner RH, Riemer BL. Important aspects of evaluation include: occipital condyle integrity. At this level study the middle GHL and the anterior labrum. Again look at the first MR-images and decide what is going on. Unfortunately, but not unexpectedly, conservative management failed with near-dislocation. 4+3 points. The contractile force of the ligamenta flava presses the vertebrae together and keeps them aligned. WebThe mission of Urology , the "Gold Journal," is to provide practical, timely, and relevant clinical and scientific information to physicians and researchers practicing the art of urology worldwide; to promote equity and diversity among authors, reviewers, and editors; to provide a platform for discussion of current ideas in urologic education, patient engagement, Detection of partial-thickness supraspinatus tendon tears: is a single direct MR arthrography series in ABER position as accurate as conventional MR arthrography? Should we just splint and go? It is interesting to note that the word chauffeur comes from the French for "someone who warms" the car engine. In adults, the commonest form of buckle fracture by far is a buckle fracture of the ribs. Translation/rotation is the result of displacement in the horizontal plane. The images are of a patient with a typical bamboo spine as a result of ankylosing spondylitis. A CT scan may also be ordered to clarify the fracture The small size of the glenoid fossa and the relative laxity of the joint capsule renders the joint relatively unstable and prone to subluxation and dislocation. Browner BD. The anterior labrum is absent in the 1-3 o'clock position and there is a thickened middle GHL. However the distraction is the most important finding, i.e. Epidemiology. In these cases, while the fracture does not require anatomical reduction, the carpometacarpal joint requires reduction and fixation as described above. A recess more than 3-5 mm is always abnormal and should be regarded as a SLAP-tear. 2. The Journal Minimal anterior displacement of the upper vertebral body.

The x-ray of the C-spine in this patient was normal and did not show the fracture. ADVERTISEMENT: Radiopaedia is free thanks to our supporters and advertisers. In most trauma situations, orthogonal views of the affected bone or joint are obtained. Benjamin W. Iles, Julie B. Samora, Satbir Singh, Lynne Ruess. Weber C Fractures. Retropulsion of a fragment is the typical feature of a burst fracture and distinguishes it clearly from a simple compression fracture. 2005;22 (3): 232-3. Burst is the result of compression with severe axial loading. The PLC is composed of the supraspinous ligaments, interspinous ligaments, articular facet capsules, and ligamenta flava (figure). The disc space is markedly widened about four times the normal level. 2002;33 (6): 503-5. ADVERTISEMENT: Radiopaedia is free thanks to our supporters and advertisers. Pylon fractures of the ankle: a distinct clinical and radiologic entity. Skinner HB. In type II there is a small recess. Sometimes a cast may be applied, but often a splint is all that is required with a period of rest and immobilization. Unlike other classifications, the TLICS is an easy scoring system that depicts the features important in predicting spinal stability, future deformity, and progressive neurologic compromise. the removal of the acromion distal to the synchondrosis may further destabilize the synchondrosis and allow for In that position the 3-6 o'clock region is imaged perpendicular. It has a role in determining treatment. So here is a typical case of distraction. Dec 2005; 29(6): 339-342. by Saad B. Chaudhary, Heidi Hullinger, and Michael J. Vives Unable to process the form. Clin Orthop Surg. The facet joints are separated on both sides. Sometimes at this level labral tears at the 3-6 o'clock position can be visualized. Clavicular fracture. The rotator cuff muscles and tendons act to stabilize the shoulderjoint during movements. In the TLICS classification however this is a burst fracture, i.e. Case 13: bilateral neonatal clavicle fractures, Case 15: birth trauma - left clavicle fracture, Case 17: fractured clavicle and bent ORIF cannulated screw, Neer classification of clavicle fractures, Allman classification of clavicle fractures, Robinson classification of clavicle fractures, Gustilo Anderson classification (compound fracture), Anderson and Montesano classification of occipital condyle fractures, Traynelis classification of atlanto-occipital dissociation, longitudinal versus transverse petrous temporal bone fracture, naso-orbitoethmoid (NOE) complex fracture, cervical spine fracture classification systems, AO classification of upper cervical injuries, subaxial cervical spine injury classification (SLIC), thoracolumbar spinal fracture classification systems, AO classification of thoracolumbar injuries, thoracolumbar injury classification and severity score (TLICS), Rockwood classification (acromioclavicular joint injury), Neer classification (proximal humeral fracture), AO classification (proximal humeral fracture), AO/OTA classification of distal humeral fractures, Milch classification (lateral humeral condyle fracture), Weiss classification (lateral humeral condyle fracture), Bado classification of Monteggia fracture-dislocations (radius-ulna), Mason classification (radial head fracture), Frykman classification (distal radial fracture), Hintermann classification (gamekeeper's thumb), Eaton classification (volar plate avulsion injury), Keifhaber-Stern classification (volar plate avulsion injury), Judet and Letournel classification (acetabular fracture), Harris classification (acetebular fracture), Young and Burgess classification of pelvic ring fractures, Pipkin classification (femoral head fracture), American Academy of Orthopedic Surgeons classification (periprosthetic hip fracture), Cooke and Newman classification (periprosthetic hip fracture), Johansson classification (periprosthetic hip fracture), Vancouver classification (periprosthetic hip fracture), Winquist classification (femoral shaft fracture), Schatzker classification (tibial plateau fracture), AO classification of distal femur fractures, Lauge-Hansen classification (ankle injury), Danis-Weber classification (ankle fracture), Berndt and Harty classification (osteochondral lesions of the talus), Sanders CT classification (calcaneal fracture), Hawkins classification (talar neck fracture), anterior superior iliac spine (ASIS) avulsion, anterior cruciate ligament avulsion fracture, posterior cruciate ligament avulsion fracture, avulsion fracture of the proximal 5th metatarsal, angulation and fracture end displacement (including direction), degree of overlap (measurement is useful), associated findings and relevant negatives.

For unstable distal clavicular fractures, a coracoclavicular screw fixation could be performed 6. If it appears that the fracture is unstable and cannot be held in place and good alignment with just a splint or cast, an open reduction and internal fixation (ORIF) may be needed. However, the terms are often used interchangeably. The fibers of the subscapularis tendon hold the biceps tendon within its groove. B. J. Manaster, David A. Additionally, cosmetic concerns may be an indication for internal fixation to avoid unsightly deformity. In many cases, however, there is no good correlation with the necessity for surgery. 10. extra-articular fracture; there may be posterior displacement of the distal segment; more: supracondylar fracture; Lateral condyle fracture. fracture may arise as proximally as the level of fibular neck and not visualized on ankle films, requiring knee or full-length tibia-fibula radiographs (Maisonneuve fracture) unstable: usually requires ORIF; Weber C fractures can be further subclassified as 6. For these reasons the Spine Trauma Study Group introduced in 2005 the Thoracolumbar Injury Classification and Severity Scale (1), with intention to be a reliable, ease-to-use tool to facilitate clinical decision making and as a practical alternative to cumbersome classification systems already in use. Check for errors and try again. Differentiating stable buckle fractures from other distal radius fractures: the 1-cm rule. Dislocation of the long head of the biceps will inevitably result in rupture of part of the subscapularis tendon. A torus is the convex portion of the upper part of the base of a Greek column and resembles the appearance of the cortical buckling seen in the "column" of bone which has been fractured in the pattern discussed in this article. It is a severe injury since there is a high chance of cord injury when its osseous and ligamentous supporting structures are pulled apart. Omid R, Kidd C, Yi A, Villacis D, White E. Measurement of Clavicle Fracture Shortening Using Computed Tomography and Chest Radiography. Here a fracture that just looks like another compression fracture on the lateral view.

The lateral view shows the typical features of a burst fracture. elderly)3-5. 2 points combined with the PLC injury making a total of 5 points. In the Denis classification this would be a three column fracture -anterior/middle/posterior - indicating a very unstable fracture. Indirect MR arthrography of the shoulder: use of abduction and external rotation to detect full- and partial-thickness tears of the supraspinatus tendon. Frequently when you have a good CT, you have most of the anatomic information. You could call these compression fractures. The fractures involve the medial malleolus, the posterior aspect of the tibial plafond (referred to as the posterior malleolus) and the lateral malleolus. In many cases the axis of the supraspinatus tendon (arrowheads) is rotated more anteriorly compared to the axis of the muscle (yellow arrow). 2. 4. If there was a lot of fluid in the joint, we should call this indeterminate. The concavity at the posterolateral margin of the humeral head should not be mistaken for a Hill Sachs, because this is the normal contour at this level. Patients with a rigid spine are more at risk for translation or distraction. Radiology Review Manual. The Spine Journal is the #1 ranked spine journal in the Having three parts, this is a more unstable fracture and may be associated with ligamentous injury. ongoing local pain, brachial plexus irritation, cosmetic deformity 5. Notice that on a 2.5mm axial slice you can miss these fractures. morphology: 4 points. Missed clavicular fracture; inadequate radiograph or occult fracture? This has been challenged by some authors, who have found non-union rates of up to 15-17%9 and high rates of a suboptimal outcome, e.g. The midshaft fracture dominance is due to two factors: firstly this is the thinnest part of the bone, and secondly, it is the only part of the bone not reinforced by attached musculature and ligaments 3.

The integrity of the posterior ligamentous complex plays an important role in the TLICS. A compression fracture gets 1 point. 2019;42(1):69-73. Check for errors and try again. The term torus is the Latin word meaning protuberance. Skeletal Trauma. Trimalleolar Ankle Fractures. If the distraction is the main feature, then the morphology is distraction, i.e. Xing W, Xing WY, Xing SL, Xing WL, Xing KZ, Xing ZC, Xing ZZ, Xing. All we see is a cortical disruption in the upper anterior wall of the vertebral body and slight loss of height ventrally. 2004;6 (6): 397-401. Radiologic history exhibit. Commonly missed subtle skeletal injuries in children: a pictorial review. If compression is the main feature, then the morphology is burst, i.e. Minimally Invasive Orthopaedic Trauma. Emerg Radiol. It is present in approximately 1.5% of individuals. The TLICS describes injury morphology as a pattern; it is not a mechanism of injury. fracture of vertebral body and Torus fracture. It also decreases the fracture gap and decreases stress on the orthopedic implant. The small size of the glenoid fossa and the relative laxity of the joint capsule renders the joint relatively unstable and prone to subluxation and dislocation. In part II we will discuss shoulder instability. Uzelac A, Davis R. Blueprints Radiology. Radiology. Notice the rotator cuff interval with coracohumeral ligament. 9. Usually it is an incidental finding and regarded as a normal variant. The PLC is injured with a fracture through the adjacent spinous processes. This classification was first described by the Belgian general surgeon,Robert Danis (1880-1962), in 1949. (2014) Journal of clinical orthopaedics and trauma. Odontoid process fracture, also known as a peg or dens fracture, occurs where there is a fracture through the odontoid process of C2. Radiographics. Saura-Ingles A, Garcia-Ballesta C, Prez-Lajarin L, Lpez-Jornet P. Fracture in the Chin Area: An Unusual Case of Mandibular Torus Fracture. intramedullary titanium elastic nail) has shown to result in a better cosmetic outcome and higher rates of union. When there is a distraction on the posterior side, the PLC is always involved, making a total of 4+3=7 points. Notice superior labrum and attachment of the superior glenohumeral ligament. This density does not mean that it involves an older fracture that is already healing with sclerosis. The ABER view is also very useful for both partial- and full-thickness tears of the rotator cuff. CJEM. ADVERTISEMENT: Supporters see fewer/no ads, Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. Trimalleolar fracture. This is the severe variant of a compression fracture with higher risk of neurologic deficits. In cases where there is significant displacement, angulation, shortening (>2 cm or >10%)9 or comminution, internal fixation either with plate-and-screw fixation or with a medullary device (e.g. Since this is not possible with the clavicle, AP and axial views are obtained: In most instances, the fracture is evident clinically and easily identified on radiographs. Modifiers are other factors which can affect the decision of appropriate treatment: Multiple rib fractures at the same levels. Falls, motor vehicle collisions, pedestrian accidents, cycling and diving are common causes of injury 6,7. In the Denis classification a burst fracture is classified as a two-column injury, calling it unstable and requiring surgical stabilization. of the biceps in the bicipital groove. 8. Both of these commonly used systems fail to systematically take into account the neurological status of the patient and the indication for MRI to determine the integrity of the posterior ligamentous complex. 1988;168 (1): 215-8. Plint AC, Perry JJ, Tsang JL. Trimalleolar fractures refer to a three-part fracture of the ankle. Without the rotator cuff, the humeral head would ride up partially out of the glenoid fossa, lessening the efficiency of the deltoid muscle. Coracoclavicular screw fixation for unstable distal clavicle fractures. Skeletal trauma, basic science, management, and reconstruction. The level with the highest TLICS score will determine the type of treatment. A sublabral recess however is located at the site of the attachment of the biceps tendon at 12 o'clock and does not extend to the 1-3 o'clock position. (2009) ISBN:1416022201. This classification was first described by the Belgian general surgeon,Robert Danis (1880-1962), in 1949. Check for errors and try again. The facet joints act against rotational forces. 40 (5): 1355-1382. The total score predicts the need for surgery as is shown in the TLICS algorithm. It should always be possible to trace the middle GHL upwards to the glenoid rim and downwards to the humerus.

Absolute indications for surgery include open fractures, patients with skin compromise or tenting, associated neurovascular injury or scapular neck fractures 9. Garca-Mata S & Hidalgo-Ovejero A. Distal Radial Torus Fracture in an Adult. This next case has a great teaching point. The supraspinous ligament is a strong, cordlike ligament which connects the tips of the spinous processes from C7 to the sacrum. The MRI demonstrates rupture of the flava ligaments, interspinous and supraspinous ligaments as well as fracture of the posterior elements and compression of the vertebral body. Indian J Orthop. It was later modified and popularized by the Swiss orthopedic surgeon,Bernhard Georg Weber (1929-2002),in 1972 2. TLICS score based on imaging is 7 points: In this case there is severe compression of the vertebral body. In this case the main findings are the horizontal fractures of the posterior elements. These type of fractures are more common in children, especially aged 5-10 years, due to the elasticity of their bones. (2006) ISBN:0071438335. However the most important findings are the horizontal fractures of the posterior elements. Radiology reports should not only include whether or not a fracture is present but also comment on: In cases where the clavicle is thought to be fractured clinically, but where the radiograph is normal, it is advisable to treat patients as if a fracture is present; this is especially the case in children 2. MRI of the shoulder second edition Closed treatment of displaced middle-third fractures of the clavicle gives poor results. 5. The following suggest complete healing : Radiology Key. Pediatric wrist buckle fractures. 2011;12 (4): 185-92. First look at the first CT-images and decide what is going on. In some cases it is difficult to decide whether you are dealing with distraction combined with a compression fracture or with a compression fracture with PLC-injury. They occur between the ages of 4 and 10 years. by Michael Zlatkin. 2 points for morphology. Unable to process the form. 2008;15 (6): 391-8. Differential diagnosis You could argue that these fractures of the spinous processes indicate distraction, i.e. On a MR-arthtrogram a sublabral foramen should not be confused with a sublabral recess or SLAP-tear, which are also located in this region. RadioGraphics 2013; 33:2031-2046, by Vaccaro AR et al. The primary feature is pulling apart. Check for errors and try again. Since the integrity of the PLC depends mostly on ligamentous structures, MR is sometimes needed to adequately diagnose pathology of the PLC, especially when there is no dislocation or disruption on CT. MRI has a tendency to overdiagnose PLC injury (4). Injury. In part III we will focus on impingement and rotator cuff tears. Widening of the interpedicular distance, often a result of the sagittal fracture, is seen in 80% of burst fractures. There are 3 types of attachment of the superior labrum at the 12 o'clock position where the biceps tendon inserts. In either case the TLICS-score is high and this patient is a surgical candidate. Mohammed R, Syed S, Metikala S et-al. On these axial images a Buford complex can be identified. In some cases it can be difficult to decide whether there is a translation or distraction injury and we have to assume that the traumtic mechanism is a combination of forces. 20 (3): 819-36. The posterior vertebral cortex is intact. 4. What are the findings? Dr. Tom Forbes Editor-in-Chief. An os acromiale must be mentioned in the report, because in patients who are considered for subacromial decompression, So this is a distraction fracture, also known as Chance fracture. TLICS: distraction injury + PLC disruption. The posterior cortex may bulge slightly posteriorly in a simple compression fracture. The Weber ankle fracture classification(or Danis-Weber classification) is a simple system for classification of lateral malleolar fractures, relating to the level of the fracture in relation to the ankle joint, specifically the distal tibiofibular syndesmosis. 2+3 points. Indian J Orthop. These descriptions may thus be misleading. It is seen in 11% of individuals. The abduction external rotation (ABER) view is excellent for assessing the anteroinferior labrum at the 3-6 o'clock position, Dr. Thomas L. Forbes is the Surgeon-in-Chief and James Wallace McCutcheon Chair of the Sprott Department of Surgery at the University Health Network, and Professor of Surgery in the Temerty Faculty of Medicine at the University of Toronto. Images in the ABER position are obtained in an axial way 45 degrees off the coronal plane (figure). They are usually seen in children, frequently involving the distal radial metaphysis. Citations may include links to full text content from PubMed Central and publisher web sites. Notice MGHL, which has an oblique course through the joint and study the relation to the subscapularis tendon. A sublabral foramen or sublabral hole is an unattached anterosuperior labrum at the 1-3 o'clock position. Loss of normal low signal intensity of the ligamenta flava or supraspinous ligaments on T1 and T2. The os acromiale may cause impingement because if it is unstable, it may be pulled inferiorly during abduction by the deltoid, which attaches here. Int Orthop. This type of fracture includes all fractures that are the result of displacement in the horizontal plane: side-to-side motion, either left-to-right or anterior-to-posterior or side-to-side rotary motion of one vertebral body with respect to another. The horizontal fractures on the posterior side and the increased interspinous distance indicate distraction, which means a higher score for morphology. The image shows the typical findings of a sublabral recess. where most labral tears are located. Notice rotator cuff muscles and look for atrophy. In this case some would call this a burst fracture with PLC-injury i.e. You have to decide what you think is the main issue: the collapse of the vertebral body or the distraction. Alao D, Guly HR. J Am Acad Orthop Surg. W B Saunders Co. (2003) ISBN:0721691757. 1. Epidemiology. In these cases the PLC is always involved, resulting in a total of 7 points for the TLICS-score. The interspinous ligaments are weak, thin, membranous structures connecting the adjacent spinous processes. McGraw-Hill Medical. Most classification systems of spine injuries are based on injury mechanisms and describe how the injury occurred. ADVERTISEMENT: Supporters see fewer/no ads, Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. Only the level with the highest score counts. Notice coracoclavicular ligament and short head of the biceps. In this case the CT shows 2 fractures and the MRI shows 3 fractures. Avulsion fractures or transverse fractures of spinous processes or articular facets. However notice the following: Even though there is not much displacement at this moment, we should probably call this translation injury. Solan MC, Rees R, Daly K. Current management of torus fractures of the distal radius. Browner BD. After a fall on his back no fracture was seen on the x-rays. When it is complicated by a burst, it gets an additional 1 point, resulting in 2 points. unstable or oblique fractures; Union rates of surgical management approach. Br Dent J. 2009 Nov 1;34(23):E841-7. The posterior cortex of the vertebral body has to be intact and this feature differentiates a simple compression fracture from the more severe burst fracture. 2009;58 (10): E1-6. How would you describe the morphology and the PLC? 1. Look for supraspinatus-impingement by AC-joint spurs or a thickened coracoacromial ligament. Using the popular Denis three-column classification may lead to another situation since it uses the terms stable and unstable. However in this case the compression is the most prominent finding. Hoogervorst P, van Schie P, van den Bekerom M. Midshaft Clavicle Fractures: Current Concepts. coracoacromial arch and coracoacromial ligament, glenohumeral ligaments - SGHL, MGHL, IGHL (anterior band). Fractures are best visualized on coronal and sagittal reformatted images. There is severe narrowing of the spinal canal. 3. Based on imaging alone, the TLICS score is 5 points and this patient is a surgical candidate. 2015;111 (21): 377-88. fractures involving a single facial buttress, Meyers and McKeevers classification (anterior cruciate ligament avulsion fracture), Watson-Jones classification (tibial tuberosity avulsion fracture), Nunley-Vertullo classification (Lisfranc injury), pelvis and lower limb fractures by region. Notice that the biceps tendon is attached at the 12 o'clock position. Skeletal Radiol. Finally a posterior spondylodesis was performed. However when we classify according to the TLICS-score, we give 4 points for the morphology and 3 points for the PLC. ISBN:1405104600. Macheras G, Kateros KT, Savvidou OD, Sofianos J, Fawzy EA, Papagelopoulos PJ. Levine AM, Jupiter JB et-al. If you look back, see how nicely it correlates with the PLC-injury on the MRI. This guideline covers assessing and managing pelvic fractures, open fractures and severe ankle fractures (known as pilon fractures and intra-articular distal tibia fractures) in pre-hospital settings (including ambulance services), emergency departments and major trauma centres. Two-thirds of patients with persistent complaints opt for further surgical intervention9. 4 points. A Buford complex is a congenital labral variant. A bony Bankart lesion shows besides the soft tissue damage also a fracture of the anteroinferior glenoid rim. Clavicular fractures are most common in young adults and elderly women 8. Sagittal Musculoskeletal Imaging,The Requisites (Expert Consult - Online and Print), 4th ed (2013). It is a severe type of injury, which always involves the PLC. Evaluation of the syndesmotic-only fixation for Weber-C ankle fractures with syndesmotic injury. The treatment will depend on the PLC integrity and the neurological status. On MR an os acromiale is best seen on the superior axial images. There is not much else happening here. LWW. A distraction injury is separation or pulling apart of two adjacent vertebrae. The Thoraco-Lumbar Injury Classification and Severity score (TLICS) is a classification system for thoracolumbar spine injuries, designed to assist in clinical management. Wolters Kluwer 2014. They usually require minimal treatment, which relies on analgesia and a collar-and-cuff. (2018) Orthopedic Traumatology. Always go for the highest possible score in TLICS. 8. For example, in a translation/rotation injury, the PLC is always involved, making a total of 3+3=6 points. This fracture is the second most common distal humerus fracture in children. Weber C Fractures. by Alexander R. Vaccaro et al. This system divides tibial plateau fractures into six types: Schatzker I: wedge-shaped pure cleavage fracture of the lateral tibial plateau, originally defined as having less than 4 mm of depression or displacement Schatzker II: splitting and depression of the lateral tibial plateau; namely, type I fracture with a depressed On the right with kyphosis. It is important to recognise these variants, because they can mimick a SLAP tear. 4 points for morphology. The undersurface of the supraspinatus tendon should be smooth. Fall onto the shoulder or onto an outstretched arm can cause this. Weber classification of ankle fractures. In Shoulder MR-Part I we will focus on the normal anatomy and the many anatomical variants that may simulate pathology. A torn PLC has a tendency not to heal and can lead to progressive kyphosis and collapse. Hernandez JA, Swischuk LE, Yngve DA et-al. A burst fracture gets 2 points for morphology in the TLICS. Study the inferior labral-ligamentary complex. Vertebral fractures and concomitant fractures of the sternum, Management of Acute Spinal Fractures in Ankylosing Spondylitis, Integrity of the Posterior Ligamentous Complex. Topics covered include: trauma systems and management; surgical procedures; epidemiological studies; The different morphology patterns will be discussed more in detail in the following chapter. In type I there is no recess between the glenoid cartilage and the labrum. WebUrology Radiology Nephrology. 2011;45 (5): 454-8. Retropulsion of posterosuperior vertebral body fragment. May, David G. Disler. Notice that there are 3 vertebrae involved. Some of the injuries thought to be due to extension mechanisms, however, turn out to be due to flexion and vice versa. Often unilateral or bilateral facet dislocation is seen in rotational fractures. The midshaft fracture dominance is due to two factors: firstly this is the thinnest part of the bone, Radiology reports should not only include whether or not a fracture is present but also comment on: For unstable distal clavicular fractures, a coracoclavicular screw fixation could be performed 6. Hill JM, Mcguire MH, Crosby LA. Now in this case there are lots of other things going on, but sometimes these little pieces of bone are all you get. Dtsch Arztebl Int. A SLAP tear may extend to the 1-3 o'clock position, but the attachment of the biceps tendon to the superior labrum should always be involved. Failure of one of the acromial ossification centers to fuse will result in an os acromiale. This is not always the case. even greater mobility of the os acromiale after surgery and worsening of the impingement (4). 5. Labral tears {"url":"/signup-modal-props.json?lang=us\u0026email="}, Bickle I, Lustosa L, Iqbal S, et al. Notice red arrow indicating a small Perthes-lesion, which was not seen on the standard axial views. You have to look at the thin slices to detect such a subtle fracture. Study the labrum in the 3-6 o'clock position. WebAn anterior-posterior (AP) X-ray of the pelvis and a cross-table lateral X-ray of the effected hip are ordered for diagnosis. The role of the radiologist is to report the following: One of the key points here is that an incomplete cord lesion will likely benefit more from surgery than a complete lesion; therefore a complete cord injury is scored as only 2 points, while an incomplete cord injury gets 3 points.
