Aseptic bone necrosis among U.S. Navy divers: survey of 934 nonrandomly selected personnel.

چکیده
Nine hundred thirty-four U.S. Navy divers were selected and surveyed radiographically using standard techniques developed for detecting aseptic bone necrosis (ABN). X rays were read by qualified radiologists. A total of 16 positive cases was detected, and another 11 were interpreted as doubtful. ABN was found to be related to age and number of months in diving. After controlling for these factors, ABN could not be related to any of seven indices of diving activity. Divers with ABN did, however, have a history of more treatments for decompression sickness (DCS) than did divers without ABN. Implications of these findings are discussed, and the suggestion is made that ABN and DCS may not be related causally, but may be related to a third common factor. The need for controlled studies is discussed. The conclusion is made that the low prevalence rates of ABN among U.S. Navy divers cannot be related to any specific index of diving activity, and may not be causally related to DCS.

The nontechnical causes of diving accidents: can U.S. Navy divers learn from other industries?
Although U.S. Navy diving is remarkably safe, because of the high-risk environment in which military divers work, accidents and mishaps do occur. Failures in leadership and situation awareness (particularly in risk and time assessment) were found to be the two most common causes of fatal and nonfatal U.S. Navy diving accidents and near misses. Responses to an attitude survey showed that junior ...
متن کاملAseptic Necrosis of Bone in a Compressed
This paper reports a detailed examination of three lesions of aseptic necrosis of bone occurring in a man who had worked in compressed air eleven years previously. Although two of the lesions were juxta-articular, in neither had the bone collapsed. Histology of only one similar lesion is reported in the literature (McCallum Ct a!. 1966). Necropsy material is considered, together with radiograph...

The study examined hearing threshold for Navy special operations personnel (SEALS (Sea-Air-Land): N = 212; divers: N = 165). Hearing threshold values were obtained and age adjusted using Mantel Haenzel Weighted odds ratio (MHOR) to compare with information in the Navy Hearing Conservation Database. For any threshold above 20 dB in the 500 through 3000 Hz range, the SEALS were significantly less...

OBJECTIVES: To better understand how human error contributes to U.S. Navy diving accidents. BACKGROUND: An analysis of 263 U.S. Navy diving accident and mishap reports revealed that the human factors classification were not informative for further analysis, and 70% of mishaps were attributed to unknown causes; only 23% were attributed to human factors. METHOD: Five diving fatality reports were ...
