title: Dysbaric osteonecrosis in Turkish sponge divers.
abstract: Skeletal radiographs were performed to determine the prevalence of dysbaric osteonecrosis (DON) in 51 Turkish sponge divers. DON was correlated with the diver's age and experience, maximum diving depth, and decompression sickness (DCS). Thirty-six of the 51 divers had radiographic evidence of one or more lesions, for a prevalence of 70.6% DON. Proximal humerus was the most effected site. Type B (head, neck, and shaft) lesions were most common, comprising 63.6% of all DON lesions. Type A (juxta-articular) lesions were observed in all 10 divers who complained of painful motion of their shoulder or hip joints. DON most commonly affected the proximal humerus. Reportedly, 38 of these 51 (74.5%) divers had experienced DCS. We did not fnd any significant relationship between DON and DCS, maximum diving depth, diving experience, and divers' age.
