We describe a 46-year-old woman who presented at intervals of seven years with osteonecrosis of the outer end of both clavicles. The clinical, radiological features and the appearances of the bone scans are described. Although the condition may be confused with osteolysis there is a dear histological distinction between the two conditions. If the symptoms fail to respond to conservative treatme...

vertebra plana is a radiological diagnosis that indicates complete compression of the vertebral body.(1,2) this condition was reported in langerhans cell histiocytosis including eosino-philic granuloma,(3, 12) ewing's sarcoma,(2,13,14) tuberculosis,(15,16) vertebral osteomyelitis,(17) aseptic necrosis,(18) aneurysmal bone cyst,(19) osteosarcoma,(20) neuroblastoma,(21) acute leu-kemia,(22) rhabd...

1. Aseptic necrosis of bone is a serious chronic complication of deep-sea diving and compressed-air work. 2. The changes to the bone which occur in this condition take time to develop to the stage where they cause the radiographic signs of bone necrosis, and consequently there is a delay of some months between the causal incident and the first diagnosis by radiography. 3. As a possible method f...

A case of aseptic necrosis of the medial segment of the clavicle with X-ray images of fragmentation and few clinical symptoms is presented. This condition develops spontaneously and leads to early sternoclavicular osteoarthritis. The benign nature of the disease and the absence of treatment make it important to establish the correct diagnosis, differentiating it from other disorders in this area.

Two patients with sickle cell disease presented with joint pain and early x-ray evidence of articular cartilage loss. Both later developed increasingly destructive arthritis with chronic synovitis identified in synovial biopsies. One patient developed demonstrable aseptic necrosis. Destructive arthropathy is much less common than the frequent transient effusions in sickle cell disease.
