Distribution of lesions in the head and neck of the humerus and the femur in dysbaric osteonecrosis.
In a prospective investigation of 164 cases of dysbaric osteonecrosis out of a total of 1269 hyperbaric workers, we found that lesions are apt to occur more frequently in some sites of the head and neck of the femur and humerus than in others. Defining the susceptibility of sites with radiographs has improved our ability to make early diagnoses because we are able to estimate the likelihood of a definite lesion of osteonecrosis developing. We have found that when the trabeculae in a susceptible site appear disordered or have translucent areas, the site often develops into osteonecrosis in a few years.
