The authors present a case of isolated scaphoid dislocation in a 40-year-old male that was undiagnosed for 2 months. The patient was treated by open reduction, Kirschner wire fixation, interosseous ligament repair using a suture anchor and Blatt's dorsal capsulodesis. At 6 years followup, his radiographs of wrist showed a normal carpal alignment with a scapholunate gap of 3 mm and no evidence of avascular necrosis (AVN) of the scaphoid.

We report on the case of bilateral avascular osteonecrosis (AVN) of the lunate and triquetrum in a 45-year-old woman without any relevant medical history for which the cause could not be established. She was treated conservatively with splinting and analgesics. The patient was able to pursue her work and hobbies with subnormal range of motion at 1-year follow-up. AVN of the triquetrum is very rare, as it is a richly vascularized bone. The presence of AVN in multiple carpal bones has only been described in patients receiving high doses of corticosteroids...

L A Archer, A Furey
PURPOSE: Avascular necrosis (AVN) of the humeral head is a devastating complication of proximal humeral fracture (PHF) that often results in long-term morbidity for the patient. Rates of AVN depend on the number of fracture fragments and are highly variable. The literature suggests that timely stable and anatomic reduction may decrease the rate at which AVN develops after PHF. To our knowledge, there is no literature published investigating a temporal relationship between the timing of PHF fixation and rates of AVN...

BACKGROUND: Operative treatment of the scaphoid nonunion includes avascular corticocancellous and cancellous bone grafts and increasingly the use of vascular pedicled and free vascular corticocancellous grafts. Especially the latter require a fair amount of operative expertise and experience in microsurgical techniques. OBJECTIVE: Which criteria lead to the decision for or against an avascular graft used for reconstruction of scaphoid nonunion? Is our current classification system of a scaphoid pseudarthrosis able to illustrate our diagnostic potential in a way that makes us refer to operative procedures? METHODS: Evaluation of current literature and expert opinions RESULTS: Avascular bone grafts show a high union rate as long as a sufficient vascularisation of the remaining fragments is present...

BACKGROUND: An unstable slipped capital femoral epiphysis (SCFE) is associated with a high rate of avascular necrosis (AVN). The etiology of AVN seems to be multifactorial, although it is not thoroughly known. The aims of our study were to determine the rate of AVN after an unstable SCFE and to investigate the risk factors for AVN, specifically evaluating the notion of an "unsafe window", during which medical interventions would increase the risk for AVN. METHODS: This retrospective multicenter study included 60 patients with an unstable SCFE diagnosed between 1985 and 2014...

Radiotherapy (RT) is an important component of treatment for malignant tumours and avascular necrosis (AVN), which is often associated with high morbidity and disability, frequently accompanies this type of therapy. It generally develops in the same extremity with the treated region and may continue long after the treatment is completed. Early identification of AVN has the potential to reduce morbidity and improve the patient's quality of life. Herein, we present a case of contralateral humerus avascular necrosis diagnosed immediately after the first round of RT in a patient with breast cancer...
