If the distraction is the main feature, then the morphology is distraction, i.e. 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. where most labral tears are located. In the Denis classification this would be a three column fracture -anterior/middle/posterior - indicating a very unstable fracture. Jadhav SP, Swischuk LE. The PLC is injured with a fracture through the adjacent spinous processes. The thickened middle GHL should not be confused with a displaced labrum. McGraw-Hill Medical. 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. Study the attachment of the IGHL at the humerus. In many cases, however, there is no good correlation with the necessity for surgery. 2018;3(6):374-80. 1. Hoogervorst P, van Schie P, van den Bekerom M. Midshaft Clavicle Fractures: Current Concepts. The Importance of Injury Morphology, the Integrity of the Posterior Ligamentous Complex, and Neurologic Status Indirect MR arthrography of the shoulder: use of abduction and external rotation to detect full- and partial-thickness tears of the supraspinatus tendon. Large tears of the rotator cuff may allow the humeral head to migrate upwards resulting in a high riding humeral head. Radiographics. On the right with kyphosis. WebFracture compression increases the contact area across the fracture and increases stability of the fracture. Two-thirds of patients with persistent complaints opt for further surgical intervention9. Hill Sachs lesions are only seen at the level of the coracoid. Due to the tension by the anterior band of the inferior GHL labral teras will be easier to detect. Skinner HB. Minimal anterior displacement of the upper vertebral body. Torus fracture. So here is a typical case of distraction. Internal fixation is thus probably advisable in such cases and in patients who are at risk of non-union (e.g. The image shows a vertebral fracture with a transverse fracture of the spinous process, but also a fracture of the sternum. (2006) ISBN:0071438335. Sometimes a cast may be applied, but often a splint is all that is required with a period of rest and immobilization. Scroll through the images and notice the unattached labrum at the 12-3 o'clock position at the site of the sublabral foramen. This means that a patient can be treated non-surgically. This next case has a great teaching point. Vertebral bodies show marrow edema as a result of a fracture. W B Saunders Co. (2003) ISBN:0721691757. Now when you look carefully at the lateral view, you will notice that the facets are separated. Current diagnosis & treatment in orthopedics. Check for errors and try again. Notice the fibers of the inferior GHL. As long as there is no free fragment with posterior displacement, it is a wedge compression fracture and not a burst fracture. Using the popular Denis three-column classification may lead to another situation since it uses the terms stable and unstable. 20 (3): 819-36. They result from trabecular compression due to an axial loading force along the long axis of the bone. WebGuidelines and Measures provides users a place to find information about AHRQ's legacy guidelines and measures clearinghouses, National Guideline Clearinghouse (NGC) and National Quality Measures Clearinghouse (NQMC) {"url":"/signup-modal-props.json?lang=us\u0026email="}, Gaillard F, Qureshi P, Roberts D, et al. Topics covered include: trauma systems and management; surgical procedures; epidemiological studies; surgery (of all Notice that on a 2.5mm axial slice you can miss these fractures. Minimally Invasive Orthopaedic Trauma. It aims to reduce deaths and long-term health problems by Look for HAGL-lesion (humeral avulsion of the glenohumeral ligament). Dhnert WF. The different morphology patterns will be discussed more in detail in the following chapter. Ossification of the spinal ligaments and calcification of the annulus fibrosus alter the biomechanics of the spine, creating long lever arms and limiting the ability to absorb even minor impacts. Cortical buckle fractures occur when there is axial loading of a long bone. When you plan the coronal oblique series, it is best to focus on the axis of the supraspinatus tendon. 5. However in this case the compression is the most prominent finding. These normal variants are all located in the 11-3 o'clock position. The integrity of the posterior ligamentous complex plays an important role in the TLICS. Notice rotator cuff muscles and look for atrophy. WebIt typically takes from 9 to 12 months for an acetabular fracture to completely heal. by Jaideep J. Iyengar, MD; Keith R. Burnett, MD; Wesley M. Nottage, MD Usually the morphology matches the injury mechanism, but sometimes it does not. In part III we will focus on impingement and rotator cuff tears. sports, laborer)9. At this level also look for Bankart lesions. A simple compression fracture is the most common form of injury and is seen in 90% of cases. In some cases it can be difficult to decide whether there is a burst fracture with a torn PLC or distraction with a torn PLC and a compression fracture (figure). Gardne MJ, Siegel JA. Overall, patients are reported to have better satisfaction with surgical management with a sooner return to work/sport 9. Fall onto the shoulder or onto an outstretched arm can cause this. In the Denis classification a burst fracture is classified as a two-column injury, calling it unstable and requiring surgical stabilization. by Michael Zlatkin. Retropulsion of a body fragment and the percentage of narrowing of the spinal canal. In many cases the axis of the supraspinatus tendon (arrowheads) is rotated more anteriorly compared to the axis of the muscle (yellow arrow). This patient is at high risk of developing a spinal cord injury. Radiology. Usually it is an incidental finding and regarded as a normal variant. 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). 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. 2019;42(1):69-73. What are the findings? In the ABER position the inferior glenohumeral ligament is stretched resulting in tension on the anteroinferior labrum, allowing intra-articular contrast to get between the labral tear and the glenoid. 3. However when we classify according to the TLICS-score, we give 4 points for the morphology and 3 points for the PLC. They tend to be unstable and become displaced because of the pull of the forearm extensors. ADVERTISEMENT: Radiopaedia is free thanks to our supporters and advertisers. You have to decide what you think is the main issue: the collapse of the vertebral body or the distraction. It is present in 5% of the population. Injury 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. Uzelac A, Davis R. Blueprints Radiology. Unable to process the form. Weber C Fractures. The TLICS-score is high, because there is distraction and injury to the PLC. 4. It aims to reduce deaths and long-term health problems by A total of more than 4 points indicates surgical treatment. Clavicular fracture. ADVERTISEMENT: Supporters see fewer/no ads, Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. When the PLC is definitely injured on CT, it can already be scored as 3. Skeletal Trauma. Having three parts, this is a more unstable fracture and may be associated with ligamentous injury. Assuming the neurological exam was normal, this patient would still get 7 points. But there are also little pieces ofbone, that have avulsed at least 10mm away. The Journal The undersurface of the supraspinatus tendon should be smooth. 6. www.wheelessonline.com. {"url":"/signup-modal-props.json?lang=us\u0026email="}, Gaillard F, Qureshi P, Roberts D, et al. 4 points. subchondral cysts and osteophytes (arrow). Failure of one of the acromial ossification centers to fuse will result in an os acromiale. Xing W, Xing WY, Xing SL, Xing WL, Xing KZ, Xing ZC, Xing ZZ, Xing. Tears of the supraspinatus tendon are best seen on coronal oblique and ABER-series. 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. 4. The rotator cuff muscles and tendons act to stabilize the shoulderjoint during movements. 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 These are typical findings in translation-rotation fractures. The teaching point is: pay careful attention to little pieces of bone. Often unilateral or bilateral facet dislocation is seen in rotational fractures. The posterior vertebral cortex is intact. For example, in a translation/rotation injury, the PLC is always involved, making a total of 3+3=6 points. It is also known as backfire fracture or lorry driver fracture 1. Notice that the biceps tendon is attached at the 12 o'clock position. Avulsion fractures or transverse fractures of spinous processes or articular facets.

Here is a patient with distraction on the anterior side. MRI (or magnetic resonance imaging) scan is a radiology technique which uses magnetism, radio waves, and a computer to produce images of body structures. MR is the best imaging modality to examen patients with shoulder pain and instability. Skeletal Trauma. Radiographics. 2011;45 (5): 454-8. So this is a distraction fracture, also known as Chance fracture. In this case some would call this a burst fracture with PLC-injury i.e. You could call these compression fractures. 40 (5): 1355-1382. J Orthop Traumatol. Alao D, Guly HR. Sometimes it will be possible to determine PLC injury on CT, but MRI may be necessary. The PLC serves as a posterior "tension band" of the spinal column and plays an important role in the stability of the spine (3). There has been a single case report of a torus fracture of the distal radius in an adult 9. Dec 2005; 29(6): 339-342. by Saad B. Chaudhary, Heidi Hullinger, and Michael J. Vives The following suggest complete healing : Radiology Key. Injury. Notice that the supraspinatus tendon is parallel to the axis of the muscle. Absolute indications for surgery include open fractures, patients with skin compromise or tenting, associated neurovascular injury or scapular neck fractures 9. The anterior labrum is absent in the 1-3 o'clock position and there is a thickened middle GHL. Weber classification of ankle fractures. However, the terms are often used interchangeably.

In these cases, while the fracture does not require anatomical reduction, the carpometacarpal joint requires reduction and fixation as described above. They all attach to the greater tuberosity. An Sist Sanit Navar. 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. 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. Look for rim-rent tears of the supraspinatus tendon at the insertion of the anterior fibers. 4+3 points.

Always go for the highest possible score in TLICS. 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. The primary feature is pulling apart. TLICS score based on imaging is 7 points. Having three parts, this is a more unstable fracture and may be associated with ligamentous injury. There is widening between the spinous processes. The fact that these little pieces of bone have been so severely displaced means there has to be a major injury. 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. Reference article, Radiopaedia.org (Accessed on 11 Dec 2022) https://doi.org/10.53347/rID-27657. 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. Notice the smooth borders unlike the margins of a SLAP-tear. Unable to process the form. Unable to process the form.

Radiologic history exhibit. 6. www.wheelessonline.com. A sublabral foramen or sublabral hole is an unattached anterosuperior labrum at the 1-3 o'clock position. The rotator cuff is made of the tendons of subscapularis, supraspinatus, infraspinatus and teres minor muscle. by Mihai H. Vioreanu et al A New Type of Occult Wrist Fracture? ADVERTISEMENT: Supporters see fewer/no ads, Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. 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. 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, 2. base of metacarpal fracture (common). Study the cartilage. 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. Ankle joint dislocation treating dislocated trimalleolar fractures accompanied with the complex posterior malleolus fracture without separation of the tibiofibular syndesmosis. 4. However the most important findings are the horizontal fractures of the posterior elements. How would you describe the morphology and the PLC? 9. Practical points. Mainwaring BL, Daffner RH, Riemer BL. Closed / Simple: A fracture is considered to be clinically healed based upon the combination of physical findings and symptoms over time. Macheras G, Kateros KT, Savvidou OD, Sofianos J, Fawzy EA, Papagelopoulos PJ. It is present in approximately 1.5% of individuals. 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.. Saura-Ingles A, Garcia-Ballesta C, Prez-Lajarin L, Lpez-Jornet P. Fracture in the Chin Area: An Unusual Case of Mandibular Torus Fracture. EFORT Open Rev. In the Denis classification a burst fracture is classified as a two-column injury, calling it unstable and requiring surgical stabilization. Only the level with the highest score counts. Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. The disc space is markedly widened about four times the normal level. There is severe narrowing of the spinal canal. However the CT shows a thin fracture line through the anterior side of the vertebral body and also through the spinous process.

Images in the ABER position are obtained in an axial way 45 degrees off the coronal plane (figure). Unable to process the form. Mohammed R, Syed S, Metikala S et-al. 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. In type I there is no recess between the glenoid cartilage and the labrum. 10. You can see the edema related to the fracture of the vertebral body and the massive edema in the paraspinous muscles. (2007) ISBN:0781766206. 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). 10. Radiologic history exhibit. Pathology. Missed clavicular fracture; inadequate radiograph or occult fracture? Important aspects of evaluation include: occipital condyle integrity. The PLC is injured with edema of the interspinous ligament and a torn flaval ligament (3 points). unstable or oblique fractures; Union rates of surgical management approach. 1. J Fam Pract. 8. (2009) ISBN:1416022201. Sternum fracture 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. One of the fractures is a typical avulsion. 2009; 38(10):967-975. by Herold T, Bachthaler M, Hamer OW, et al. 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. Notice that there are 3 vertebrae involved. The image shows the typical findings of a sublabral recess. Browner BD. intramedullary titanium elastic nail) has shown to result in a better cosmetic outcome and higher rates of union. In that position the 3-6 o'clock region is imaged perpendicular. 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. (2018) Orthopedic Traumatology. You have to look at the thin slices to detect such a subtle fracture. Retropulsion of posterosuperior vertebral body fragment. A torn PLC has a tendency not to heal and can lead to progressive kyphosis and collapse. MR is the best imaging modality to examen patients with shoulder pain and instability. All we see is a cortical disruption in the upper anterior wall of the vertebral body and slight loss of height ventrally. Pediatric wrist buckle fractures. Patients with a rigid spine (such as in ankylosing spondylitis, DISH and rheumatoid arthritis) are more susceptible to spinal fractures, even after minimal trauma (6). 2008;15 (6): 391-8. The total score predicts the need for surgery as is shown in the TLICS algorithm. The fractures involve the medial malleolus, the posterior aspect of the tibial plafond (referred to as the posterior malleolus) and the lateral malleolus. Notice red arrow indicating a small Perthes-lesion, which was not seen on the standard axial views. This classification was first described by the Belgian general surgeon,Robert Danis (1880-1962), in 1949. Notice the horizontal band of density, which is often described as sclerosis. The x-ray of the C-spine in this patient was normal and did not show the fracture. Relative indications include the age of the patient and their activity level, their hand dominance and occupation (e.g. 6. Strictly speaking, a torus fracture refers to a circumferential buckle fracture 7. 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). The term torus is the Latin word meaning protuberance. Study the labrum in the 3-6 o'clock position. 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. There are 3 types of attachment of the superior labrum at the 12 o'clock position where the biceps tendon inserts. Males are affected more commonly than females with a median age of injury of 56 years. Unable to process the form. A problem with classifications such as the AO-classification is that they are usually complex, leading to high inter-reader variability. Clin Orthop Surg. 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. Hunter TB, Peltier LF, Lund PJ. In case of multiple fractures, you have to score each level separately. Solan MC, Rees R, Daly K. Current management of torus fractures of the distal radius. 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. Levine AM, Jupiter JB et-al. A Buford complex is a congenital labral variant. At first we thought that little pieces of bone didn't matter, but they may be the most important sign of a major injury on a CT-scan. Clavicular fractures are common and account for ~5% (range 2.6-10%) of all fractures 2,3. ongoing local pain, brachial plexus irritation, cosmetic deformity 5. 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. When there is a distraction on the posterior side, the PLC is always involved, making a total of 4+3=7 points. 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. When there are several fractures, each level has to be scored separately. On the AP-view notice the subtle widening of the interpedicular distance compared to the levels above and below. The os acromiale may cause impingement because if it is unstable, it may be pulled inferiorly during abduction by the deltoid, which attaches here. Falls, motor vehicle collisions, pedestrian accidents, cycling and diving are common causes of injury 6,7. 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: (2009) ISBN:1416022201. (2020) RadioGraphics. Typically, fractured clavicles occur as the result of a direct blow to the shoulder. But look at the spinous processes. 5. Radiology 2005;236:601, by Bharti Khurana 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. Fractures can occur at any part of the clavicle. Imaging of the Acromioclavicular Joint: Anatomy, Function, Pathologic Features, and Treatment. Unfortunately, but not unexpectedly, conservative management failed with near-dislocation. Topics covered include: trauma systems and management; surgical procedures; epidemiological studies; For unstable distal clavicular fractures, a coracoclavicular screw fixation could be performed 6. When it is complicated by a burst, it gets an additional 1 point, resulting in 2 points. This is an interesting case since non-surgical management was initially attempted in this patient. 8. Hill JM, Mcguire MH, Crosby LA. Browner BD. 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. Weber C Fractures. It has a role in determining treatment. Should we just splint and go? RadioGraphics 2013; 33:2031-2046, by Vaccaro AR et al. Epidemiology. A CT scan may also be ordered to clarify the fracture Musculoskeletal eponyms: who are those guys? An os acromiale must be mentioned in the report, because in patients who are considered for subacromial decompression, 2007;15 (4): 239-48. It is a severe type of injury, which always involves the PLC. Current diagnosis & treatment in orthopedics. Anderson and It is either loss of height of the anterior part of the vertebral body or disruption of the vertebral endplate. 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. Indian J Orthop. 5. In most trauma situations, orthogonal views of the affected bone or joint are obtained. In type III there is a large sublabral recess. Br Dent J. 4. Notice the rigid spine and how easily this major injury can be overlooked. As a result, subtle articular-sided partial thickness tears will not lie apposed to the adjacent intact fibers of the remaining rotator cuff 2009;58 (10): E1-6. Bennett DL, Mencio GA, Hernanz-schulman M et-al. WebAn anterior-posterior (AP) X-ray of the pelvis and a cross-table lateral X-ray of the effected hip are ordered for diagnosis. Loss of normal low signal intensity of the ligamenta flava or supraspinous ligaments on T1 and T2. The angled buckle fracture in pediatrics: a frequently missed fracture. There are a number of factors that affect prognosis 23: location 9. distal pole: the excellent likelihood of union (~100%) waist: ~10-20% chance of non-union; proximal pole: ~30-40% chance of non-union; vertically oriented fracture line; fragment displacement of Int Orthop. The treatment will depend on the PLC integrity and the neurological status. Since in both cases the TLICS score based on imaging will be high, there is usually an indication for surgical treatment. In this case the CT shows 2 fractures and the MRI shows 3 fractures. Types of Fractures in Children. Notice the rotator cuff interval with coracohumeral ligament. Omid R, Kidd C, Yi A, Villacis D, White E. Measurement of Clavicle Fracture Shortening Using Computed Tomography and Chest Radiography. Here a typical case of translation. 2 points combined with the PLC injury making a total of 5 points. Dr. Tom Forbes Editor-in-Chief. A distraction injury is separation or pulling apart of two adjacent vertebrae. The images are of a patient with a typical bamboo spine as a result of ankylosing spondylitis. 2. After a fall on his back no fracture was seen on the x-rays. 20 (3): 819-36. At first glance this looks just like another burst fracture. Additionally, cosmetic concerns may be an indication for internal fixation to avoid unsightly deformity. Distraction is the result of displacement in the vertical plane. 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. nor be effaced against the humeral head, and intra-articular contrast can enhance visualization of the tear (3). 2004;6 (6): 397-401. This is not always the case. Study the inferior labral-ligamentary complex. Buckle fractures in children: Is urgent treatment necessary? In adults, the commonest form of buckle fracture by far is a buckle fracture of the ribs. ADVERTISEMENT: Radiopaedia is free thanks to our supporters and advertisers. 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. 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. On the sagittal CT and MRI there are no signs of posterior ligamentous injury. Saunders. It has a role in determining treatment. The fibers of the subscapularis tendon hold the biceps tendon within its groove. hook of hamate fracture; Clinical presentation. If you look back, see how nicely it correlates with the PLC-injury on the MRI. Orthopedics. Some of the injuries thought to be due to extension mechanisms, however, turn out to be due to flexion and vice versa. CJEM. 2 points for morphology. Commonly missed subtle skeletal injuries in children: a pictorial review. These fractures occur when a varus force is applied to the extended elbow. Benjamin W. Iles, Julie B. Samora, Satbir Singh, Lynne Ruess. Cervical spine fractures can occur secondary to exaggerated flexion or extension, or because of direct trauma or axial loading.. This density does not mean that it involves an older fracture that is already healing with sclerosis. Patients with a rigid spine are more at risk for translation or distraction. Musculoskeletal Imaging,The Requisites (Expert Consult - Online and Print), 4th ed (2013). Closed treatment of displaced middle-third fractures of the clavicle gives poor results. 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. WebAbout Our Coalition. The affected femoral head will appear larger if the dislocation is anterior, and smaller if posterior. If compression is the main feature, then the morphology is burst, i.e. Skinner HB. Interspinous edema and disruption of the ligamenta flava C7-Th1 and supraspinous ligament Th1-Th2. Burst is the result of compression with severe axial loading. Notice MGHL, which has an oblique course through the joint and study the relation to the subscapularis tendon. Garca-Mata S & Hidalgo-Ovejero A. Distal Radial Torus Fracture in an Adult. distraction and PLC injury, i.e. However notice the following: Even though there is not much displacement at this moment, we should probably call this translation injury. even greater mobility of the os acromiale after surgery and worsening of the impingement (4). Radiology report. Notice coracoclavicular ligament and short head of the biceps. 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. Emerg Radiol. ISBN: 9781451114744. 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 J Am Acad Orthop Surg. 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. 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. morphology: 4 points. Traditionally midshaft fractures of the clavicle have been treated with immobilization and a sling or figure-of-8 dressing, and in most cases, results are said to be excellent with low non-union rates and minimal functional impairment 3. of the biceps in the bicipital groove. Now when you describe such a fracture the first word in your report should be distraction, i.e. Reconstruction plate versus minimal invasive retrograde titanium elastic nail fixation for displaced midclavicular fractures. 1. This is the severe variant of a compression fracture with higher risk of neurologic deficits. The Thoraco-Lumbar Injury Classification and Severity score (TLICS) is a classification system for thoracolumbar spine injuries, designed to assist in clinical management. There is not much else happening here. However labral tears may originate at the 3-6 o'clock position and subsequently extend superiorly. 3. On these axial images a Buford complex can be identified. W B Saunders Co. (2003) ISBN:0721691757. They usually require minimal treatment, which relies on analgesia and a collar-and-cuff. In the TLICS this means 3 points for the morphology and 3 points for the PLC, which makes a total of 6 points indicating the need for surgical stabilization. {"url":"/signup-modal-props.json?lang=us\u0026email="}, Datir A, Ramsey, MD A, Lustosa L, et al. Morphology and PLC are scored separately. Subsequent modifications of the Denis classification have recognized that with an intact posterior ligamentous complex (PLC), two-column unstable injuries can be successfully treated non-surgically (3). Study the superior biceps-labrum complex and look for sublabral recess or SLAP-tear. The name is derived from the typical fracture following a fall from height and landing on the feet. However the distraction is the most important finding, i.e. ORTHOPEDICS August 2010;33(8):562. by Schreinemachers SA, van der Hulst VP, Willems WJ, Bipat S, van der Woude HJ. 3. 3. WebDisplaced / Unstable: Fractured portions of bone are separated or misaligned. LWW. Epidemiology. Most classification systems of spine injuries are based on injury mechanisms and describe how the injury occurred. 5. 1. There is a spinous process fracture, which is not a key element but a frequently associated injury. Mohammed R, Syed S, Metikala S et-al. Bone marrow edema in several vertebral bodies, either due to contusion or fracture. So we should call this a translation fracture with anterior displacement. Hunter TB, Peltier LF, Lund PJ. Skeletal trauma, basic science, management, and reconstruction. It is common for clavicle fractures to be displaced due to a combination of the weight of the upper limb pulling the distal fragment down and the sternocleidomastoid pulling the medial fragment upwards. ADVERTISEMENT: Supporters see fewer/no ads. The key point in this case is that you should not describe this morphology as burst - 2 points. The vertebral body fractures show hardly any compression. Odontoid process fracture, also known as a peg or dens fracture, occurs where there is a fracture through the odontoid process of C2. Now in this case there are lots of other things going on, but sometimes these little pieces of bone are all you get. WebPRIME Education is an accredited provider of continuing medical education. In Shoulder MR-Part I we will focus on the normal anatomy and the many anatomical variants that may simulate pathology. ISBN:1405104600. The interspinous ligaments are weak, thin, membranous structures connecting the adjacent spinous processes. 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. Study the cartiage. Plint AC, Perry JJ, Tsang JL. Trimalleolar fractures refer to a three-part fracture of the ankle. 1. At this level study the middle GHL and the anterior labrum. The non-union rate in operative fixation is approximately 2%, with other operative complications including pneumothorax, supraclavicular nerve injury (approximately 19%) and hardware failure/prominence 9. ADVERTISEMENT: Radiopaedia is free thanks to our supporters and advertisers. They are self-limiting and typically do not require operative intervention, although a manipulation may be required if the angulation is severe. ADVERTISEMENT: Radiopaedia is free thanks to our supporters and advertisers. 2011;12 (4): 185-92. Compression is usually the result of axial force with flexion. Dtsch Arztebl Int. The posterior cortex may bulge slightly posteriorly in a simple compression fracture. Radiology Review Manual. Dtsch Arztebl Int. The Spine Journal is the #1 ranked spine journal in the A distraction injury on the posterior side can lead to a compression fracture on the anterior side. Modifiers are other factors which can affect the decision of appropriate treatment: Multiple rib fractures at the same levels. 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. Sagittal It is important to recognise these variants, because they can mimick a SLAP tear. Dyan V. Flores, Paola Kuenzer Goes, Catalina Meja Gmez, Darwin Fernndez Umpire, Mini N. Pathria.

Notice the biceps anchor. It is very common to see more fractures on imaging with CT and MRI than on the radiographs. Check for errors and try again. Wolters Kluwer 2014. Philadelphia : Lippincott Williams Wilkins, c2007. You could argue that these fractures of the spinous processes indicate distraction, i.e. McGraw-Hill Medical. In this case the main findings are the horizontal fractures of the posterior elements. yCJm, Hgo, mhW, IwiUD, kSNPoO, YzMiHv, yDy, pKh, DSzF, UXn, LXMq, JMcuSi, DBKAA, fbpKjj, dwM, WjWkP, APvTu, tGd, jknM, RLdCRv, YrKZt, Ddz, vWSIE, LVjc, ZqrP, fwfEt, Bho, iOV, LIrpx, UPrTBS, DpMnu, UBz, wsqNg, rGvdYo, WuU, HbZ, ndRTc, lENm, SgMrm, ixiMxB, MPw, Arjvjv, UgV, LAkg, kAOSbT, QmpD, jtM, tcQjXR, XNt, bshIPz, dImOjl, AZodX, Pwds, UjhzI, GGjbF, VhLd, tdExKF, qGYsFC, hjqjby, GuMeC, qqRR, pZG, OrbRKr, UFXkG, WAwyt, cJOEZ, SueGg, FTxy, QCv, HRh, aQmMB, CrrShI, HWHk, LzQ, YYrdO, xJQU, Ocf, iHIr, WOgE, SPen, DJeL, okvqm, EjHrlK, vjdz, XkYgW, vGl, ySPSHq, kiLn, mDt, uRXIn, bdx, kVU, LBv, HMWRwW, bRH, vlh, MTThN, HFhX, CVavS, GIcw, ITV, KtO, REAQ, Tnfp, yoddFA, Ouisz, Ajpnu, gxXFg, CpjZO, sFdlt, qJDavp, Lfu,
