Dysbaric osteonecrosis (DON) is regarded as an occupational disease for caisson workers, commercial, and military divers. Magnetic resonance imaging (MRI) was suggested for the surveillance of military divers for DON. This study aimed to determine the prevalence of DON in Turkish Navy divers.
The shoulder, hip, and knee joints of 106 male divers were screened for DON with MRI. A questionnaire was used to obtain information about subjects' medical history and diving experience.
The mean age of divers was 34.3 +/- 5.8 yr. The divers had spent an average of 12.1 +/- 6.1 yr at their occupation. The average of total hours of diving was 834 +/- 458 h. The maximum diving depth was 53.0 +/- 18.4 m (175 +/- 61 ft) and the average diving depth was 13.3 +/- 8.4 m (44 +/- 28 ft). MRI examinations of divers did not reveal bone lesions consistent with osteonecrosis.
We concluded that the risk of DON is very low for military divers who strictly obey the decompression rules and who undergo periodic medical examination. The use of MRI for routine screening of military divers is not justified.
减压性骨坏死（DON）被视为沉箱工人、商业潜水员和军事潜水员的职业病。有人建议使用磁共振成像（MRI）对军事潜水员进行DON监测。本研究旨在确定土耳其海军潜水员中DON的患病率。
对106名男性潜水员的肩部、髋部和膝关节进行MRI检查以筛查DON。使用问卷获取有关受试者病史和潜水经历的信息。
潜水员的平均年龄为34.3±5.8岁。潜水员平均从业年限为12.1±6.1年。潜水总时长平均为834±458小时。最大潜水深度为53.0±18.4米（175±61英尺），平均潜水深度为13.3±8.4米（44±28英尺）。潜水员的MRI检查未发现与骨坏死一致的骨病变。
我们得出结论，对于严格遵守减压规则并定期进行体检的军事潜水员，DON的风险非常低。对军事潜水员进行常规MRI筛查没有道理。
