[Intrathoracic dislocation fracture of the head of the humerus].

We present a rare case of fracture-dislocation of shoulder with intrathoracic displacement of the humeral head. This case is well documented by CT. The mechanism and treatment modalities are discussed, and pertinent literature is reviewed.

[Aseptic osteonecrosis of the femoral condyle after meniscectomy by the arthroscopic approach].

Retrospective review of 10 patients who presented with avascular necrosis of the ipsilateral femoral condyle following arthroscopic meniscectomy (9 medial, 1 lateral). The bone lesions were evaluated by radiography and MRI, which were repeated for few patients. MRI allows earlier diagnosis of avascular necrosis of the femoral condyle and offers an evaluation of extent of the lesions whose evolution is variable: 3 patients required a knee prothesis, the other 7 patients were treated medically.
