[Degenerative changes in the coxofemoral articulation due to occupational causes. I. Radiological description of a...

With a view to initiating epidemiological studies aimed at demonstrating the causal or concausal role of certain working activities in degenerative diseases of the coxo-femoral articulations, the authors report data from a radiological study of a reference population and the necessary conditions for their correct use. Statistical analysis of the descriptive features leads to some interesting observations on the evolution with age of the radiological picture of the coxo-femoral joints (and on the aging of these joints). There was an increase with advancing age of some of the alterations that are characteristic of degenerative articular processes, such as sclerosis and osteophytosis. Reduction of articular "rima", however, occurs suddenly between the ages of 36 and 45 and does not seem to subsequently undergo any statistically significant evolution.
