Case 14398 Dysbaric osteonecrosis of the humerus

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...

[Early detection of asymptomatic dysbaric osteonecrosis of the shoulder after type 1 decompression sickness: a case report].

INTRODUCTION Dysbaric osteonecrosis is a rare illness in professional divers and compressed-air workers. The correlation between dysbaric osteonecrosis and previous decompression sickness with osteoarthromuscular pain (type 1 decompression sickness) remains a controversial subject. The probability for ischemic lesions detected with MRI to turn into osteonecrosis after decompression sickness is ...

Aseptic bone necrosis in an amateur scuba diver.

A case is reported that provides further evidence of an old occupational hazard, dysbaric osteonecrosis, presenting in a new population (sports scuba divers) who also appear to be at risk. It highlights the need for an accurate diagnosis of diving related illness.
