The first report of a suited diver with bone necrosis was made by Grutzmacher in 1941. Since 1966, when our hyperbaric chamber was constructed 155 divers were treated and 135 divers were examined radiologically. Of the 135, 72 had aseptic bone necrosis.We clasified these bone lesions according to Ota-Matsunaga's criteria. The juxta articular lesions (Atype) were found more than 20% among the divers whose experiences were more than 4 years. The lesions of aseptic necrosis in diverers are offen multiple and bilateral. We found bone lesions at upper Humerus (61), upper femur (58), lower femur and upper tibia (31), lower Humerus (7), and Pelvis (4). In our survey 75% of the dirers who had bone lesions had experience of Type I decompression sickness (bends). The juxta articular lesions were found who had dived more than 11m deeper. Problems in further study in this field were pointed out.
