Purpose The 3-category rating of volar plate prominence in relation to the most volar edge of the distal radius (the watershed line) on lateral radiographs was reliable among a small group of surgeons and associated with the probability of flexor tendon irritation and potential rupture. Classifications are often less reliable when tested among a la...

ABSTRACT Hip dislocations are classified as high–energy trauma. Femoral head fractures, although not common in orthopedic surgery, are often associated with posterior hip dislocations. The classification adopted was Pipkin (I-IV types). In this paper, we present clinical case of femoralhead fracture with hip dislocation, Pipkin type II, in a patien...

Posttraumatic osteonecrosis of the femoral head (ONFH) affects patients at different ages and may lead to functional limitation and joint replacement, with total hip arthroplasty, which is a costly procedure. Proposed methods to optimize ischemic tissue regeneration have been reported. Phosphodiesterase‐5 inhibitors act by inhibiting the degradatio...

Fractures of the distal end of the tibia without joint involvement are usually the result of high-energy trauma. Local anatomic conditions lead to high rates of infection, delayed consolidation, and exposure of fixation hardware. In this setting, minimally invasive techniques are indicated to mitigate the complications of surgical treatment. The ai...

Article
BACKGROUND: For greater tuberosity fractures, 5-mm displacement is a commonly used threshold for recommending surgery; however, it is unclear if displacement can be assessed with this degree of precision and reliability using plain radiographs. It also is unclear if CT images provide additional information that might change decision making. QUESTIO...

Purpose: Classification systems for proximal humeral fractures have limited interobserver reliability, even with advanced imaging and training. Limited interobserver reliability hinders the development of treatment and scientifi c protocols.

Fracture-dislocations of the proximal interphalangeal joint are vexing because subluxation and articular damage can lead to arthrosis and the treatments are imperfect. Ideally, a surgeon could advise a patient, based on radiographs, when the risk of problems merits operative intervention, but it is unclear if middle phalanx base fracture characteri...
