An injury resulting in an outward (valgus) stress on the elbow, such as falling on an outstretched hand causes an avulsion fracture of the medial epicondyle. [citation needed] The medial epicondyle is often the final growth plate (ossification center) to ossify in the elbow. Growth plates are particularly vulnerable to injury compared to bone.
The posterior fat pad is normally pressed in the olecranon fossa by the triceps tendon, and hence invisible on lateral radiograph of the elbow. [3] When there is a fracture of the distal humerus, or other pathology involving the elbow joint, inflammation develops around the synovial membrane forcing the fat pad out of its normal physiologic resting place.
Because dislocations make the knee unstable, 15% of patellas will re-dislocate. [27] Patellar dislocations often occur when the knee is in full extension and sustains a trauma from the lateral to medial side. [28] Elbow: Posterior dislocation, 90% of all elbow dislocations [29] Wrist: Lunate and Perilunate dislocation most common [30]
Elbow dislocations constitute 10% to 25% of all injuries to the elbow. The elbow is one of the most commonly dislocated joints in the body, with an average annual incidence of acute dislocation of 6 per 100,000 persons. [30] Among injuries to the upper extremity, dislocation of the elbow is second only to a dislocated shoulder. A full ...
Radial head fractures are a common type of elbow fracture that typically occurs after a fall on an outstretched arm. [1] They account for approximately one third of all elbow fractures and are frequently associated with other injuries of the elbow. [2] [3] Radial head fractures are diagnosed by a clinical assessment and medical imaging.
Elbow fractures are any broken bone in or near the elbow joint and include olecranon fractures, supracondylar humerus fractures and radial head fractures. [1] The elbow joint is formed by three different bones: the ulna, radius, and humerus that permit the joint to move like a hinge and allow a person to straighten and bend their arm and these bones are connected by tendons, ligaments, and ...
distal radius fracture with ulnar dislocation and entrapment of styloid process under annular ligament: Moore's fracture at TheFreeDictionary.com: Pipkin fracture-dislocation: G. Pipkin: posterior dislocation of hip with avulsion fracture of fragment of femoral head by the ligamentum teres: impact to the knee with the hip flexed (dashboard injury)
The composition of the triangular ligamentous structure on the lateral side of the elbow varies widely between individuals [1] and can be considered either a single ligament, [2] in which case multiple distal attachments are generally mentioned and the annular ligament is described separately, or as several separate ligaments, [1] in which case parts of those ligaments are often described as ...
