Dysbaric Osteonecrosis

Risk factors for dysbaric osteonecrosis.

OBJECTIVES Dysbaric osteonecrosis (DON) is a complication of ineffective decompression following exposure to high-pressure environments. This study was designed to determine risk factors for the occurrence of DON in divers. METHODS Fifty-six male divers received skeletal examinations by radiography to assess the occurrence of DON. A questionnaire was used to obtain clinical and diving informa...

Dysbaric osteonecrosis by X-ray and CT scan in Chinese divers.

OBJECTIVE To compare the results of X-ray and CT scan for dysbaric osteonecrosis in Chinese divers. METHODS Both shoulders, hips and knees of 66 asymptomatic divers with diving duration of more than one year were examined by X-ray and CT scan. RESULTS The most frequent locations of dysbaric osteonecrosis were the upper femurs, followed by the upper humerus, lower femurs and upper tibias, an...

Dysbaric osteonecrosis in recreational divers: a study using magnetic resonance imaging.

OBJECTIVE We set out to identify whether magnetic resonance imaging (MRI) would identify evidence of dysbaric osteonecrosis (DON) in a group of experienced recreational scuba divers. DESIGN Local British Sub Aqua Club divers of at least Trainee Dive Leader grade were offered MRI scans (T1 and TIRM sequences) of hips, femora and shoulders. Anonymous images were interpreted separately by two ra...
