A high proportion of mallet finger injuries will present as isolated tendon injuries without any associated avulsions fractures known as a "mallet fracture" 5. Dorsal avulsion fracture. Even when a fracture cannot be identified, the presence of joint effusion in adults should be treated as a non-displaced radial head fracture. Sayama C, Fassett D, Apfelbaum R. The Utility of MRI in the Evaluation of Odontoid Fractures. Classification. Tillaux fracture. ADVERTISEMENT: Radiopaedia is free thanks to our supporters and advertisers. 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. In reality, the majority of fractures that involve the physis have at least a small fragment of metaphysis associated with them and are therefore type II injuries. As a historical note, there are four methods of judicial hanging, and the process is more complicated than may be evident at first glance. Classification.

Looser zones are also a type of insufficiency fracture. if fat-fluid level (lipohemarthrosis), think of an intra-articular fracture; Bone cortex. Hsu W & Anderson P. Odontoid Fractures: Update on Management. As the physiological closure of the physeal plate begins medially, the lateral (open) physis is prone to this type of fracture. Potential mechanisms: violent knee flexion against a tight contraction quadriceps, e.g. The fracture extends proximally in a variable oblique direction (from essentially transverse to almost sagittal) from the distal radial articular surface through the lateral cortex of the distal radius, thus separating the radial styloid from the rest of the radius 4,5. A minimally elevated anterior fat pad may be seen on normal elbow radiographs. The anterior and middle columns fail in compression, and the posterior column fails in distraction. Strictly speaking, the fracture is misnamed and should more correctly be called "hangee" fracture.

The fracture extends proximally in a variable oblique direction (from essentially transverse to almost sagittal) from the distal radial articular surface through the lateral cortex of the distal radius, thus separating the radial styloid from the rest of the radius 4,5. The fracture requires an open physis (the lateral aspect of the distal tibial physis usually closes between 12 to 15 years of age while the medial aspect closes earlier). neurological disorders. Epidemiology. The fractures involve the medial malleolus, the posterior aspect of the tibial plafond (referred to as the posterior malleolus) and the lateral malleolus. The fracture extends proximally in a variable oblique direction (from essentially transverse to almost sagittal) from the distal radial articular surface through the lateral cortex of the distal radius, thus separating the radial styloid from the rest of the radius 4,5. Evidencebased Orthopedics. The Mason-Johnston classificationcan be used to further classify radial head fractures, although, in practice, most radiologists merely describe the injury. Eur Spine J. In reality, the majority of fractures that involve the physis have at least a small fragment of metaphysis associated with them and are therefore type II injuries. 1.

It is also sometimes termed the dorsal type Barton fracture to distinguish it from the volar type or reverse Barton fracture. It is also sometimes termed the dorsal type Barton fracture to distinguish it from the volar type or reverse Barton fracture. Injuries Involving the Epiphyseal Plate. PubMed Journals helped people follow the latest biomedical literature by making it easier to find and follow journals, browse new articles, and included a Journal News Feed to track new arrivals news links, trending articles and important article updates. The fracture commonly results from an abduction-external rotation mechanism. Having three parts, this is a more unstable fracture and may be associated with ligamentous injury. You can rate this topic again in 12 months. Insufficiency fractures are a type of stress fracture, which are the result of normal stresses on abnormal bone. mechanical stress-risers.

Improving Detection of Pediatric Elbow Fractures by Understanding Their Mechanics. Elbow effusions are best seen on a lateral projection, where fluid in the joint capsule elevates the pericapsular fat. Even when a fracture cannot be identified, the presence of joint effusion in adults should be treated as a non-displaced radial head fracture. It is for this reason that the 5 th metatarsal base must be included in the lateral ankle projection of an ankle series, especially when performed for an The fracture is seen on lateral radiographs as an oblique lucency through the spinous process, usually of C7. 4. The lateral epiphyseal involvement is due to growth plate fusion commencing from medial to lateral aspect. It assesses the pattern of fractures, involvement of the radioulnar joint and presence of a distal ulnar fracture.. Location. However, posteriorly, the pericapsular fat is usually hidden in the olecranon groove and fossa, and its presence is indicative of fluid in the joint seen as a sail sign. Typically caused by injuries from sporting activities involving jumping, most commonly basketball. It assesses the pattern of fractures, involvement of the radioulnar joint and presence of a distal ulnar fracture.. The Frykman classification of distal radial fractures is based on the AP appearance and encompasses the eponymous entities of Colles fracture, Smith fracture, Barton fracture, chauffeur fracture.

with back pain, paresthesias and positive SLR, non-weight bearing and activity restriction, compression side stress fractures + fracture line <50% width, tension side stress changes with no fracture line (MRI), 75-100% heal and can return to activity if correct indications met, compression side stress fractures with fatigue line >50% femoral neck width, compression side stress fracture with hip effusion, 8x increase risk of progression with presence of hip effusion, progression of compression side stress fractures, inverted triangle using three cannulated screws (7.0 or 7.3 mm), similar outcomes versus lower-risk FNSF treated nonoperative, effectively prevent progression to displaced fracture, more likely to result in military seperation, lower return to activity following ORIF for displaced FNSF than nondisplaced, increase 25% body weight per week until full painless full weight-bearing, three cannulated screws in inverted triangle generally preferred over two, inferior calcar provides higher load to failure, starting point should be at or above lesser trochanter to avoid stress riser, screws should be parallel with maximal spread, threads should be in head fragment and not crossing fracture line, washer may be used to stop the screw head from penetrating greater trochanter, internervous plane is femoral and superior gluteal nerve (SGN), tensor fascia lata (SGN) and sartorius (femoral), gluteus medius (SGN) and rectus femoris (femoral), reduction via anterior approach followed by separate lateral incision for implant insertion, anterior approach allow for better direct visualization of entire femoral neck, tensor fascia lata (SGN) and gluteus medius (SGN), reduction and insertion of implant performed through same approach, limited visualization of subcapital neck region, anatomic reduction is paramount to mitigate risk of osteonecrosis, early surgical intervention also reduces risk of AVN, consider autologous bone graft to mitigate nonunion risk, hip effusion associated with 8x risk of progression, size of fracture not associated with progression, factors associated with AVN in displaced FNSFs, core decompression or vascularize free-fibula graft, case reports following nonoperative treatment, likely for fracture to progress and displace, high athletic ability or demand (versus recreational athletes), Spontaneous Osteonecrosis of the Knee

Injury). They are distinct from a lateral condyle fracture which is a very different fracture despite the similar name.

A minimally elevated anterior fat pad may be seen on normal elbow radiographs. Radial head fractures. Although it appears complicated, it ADVERTISEMENT: Supporters see fewer/no ads, Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. It occurs in older children and adolescents when the medial aspect of the distal tibial growth plate has started to fuse. Pathology. Classification. Mechanism. Charles A. Rockwood (Foreword), Raffy Mirzayan (Editor), John M. Itamura (Editor). mechanical stress-risers. In more severe cases, the bone may be broken into several fragments, known as a comminuted fracture. Having three parts, this is a more unstable fracture and may be associated with ligamentous injury. Barton fractures extend through the dorsal aspect to the articular surface but not to the volar aspect. Most authors regard it as a type 4 Salter-Harris fracture. As a historical note, there are four methods of judicial hanging, and the process is more complicated than may be evident at first glance. This typically involves separation of the tibial attachment of the ACL to variable degrees. Spinal fractures are usually the result of significant trauma to a normally formed skeleton or the result of trauma to a weakened spinal column. Examples include: Further information about specific fractures can be found by anatomic site: ADVERTISEMENT: Supporters see fewer/no ads, Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. The fracture is seen on lateral radiographs as an oblique lucency through the spinous process, usually of C7. Location. Radiopaedia.org, the wiki-based collaborative Radiology resource (2005) ISBN: 9780781752862 -. 4. On plain film, dorsal avulsion injuries are best detected on a lateral projection, where typically an avulsed flake of bone is identified lying posteriorly to the triquetral bone (see pooping duck sign). Examples include: Jefferson fracture: ring fracture of C1; hangman fracture: bilateral pedicle or pars fracture of C2; dens fracture; flexion teardrop fracture: unstable flexion fracture; extension teardrop fracture: stable The mechanism of injury is variable, and can occur both during flexion or extension, and with or without compression 5.
