Incidence of Osteonecrosis in Royal Naval Divers.
Incidence data of osteonecrosis from various surveys up to 1971 are given as well as data on a group of 97 British naval divers aged 30 or over. Although differences in diagnostic standards and sampling methods invalidate true comparisons of the surveys, the ratio of shoulder to femoral-head lesions of about 3:1 is consistent. Some studies show a tendency for bone necrosis to be age-related, but the study of the 97 British naval divers shows it to be more a function of decompression or diving experience.
