[Arthroscopy of the hip].

In reference to 50 arthroscopies performed since january 1983, we describe a simplified approach to the hip. This joint may be divided, from the standpoint of arthroscopic anatomy, into a coxo-femoral area per se and a peripheral area. The latter represents the most interesting part from a rheumatologist's standpoint. This is the area that our method enables to study quite easily. With the macroscopic study and the possibility of controlled biopsy or biopsy under direct vision, arthroscopy realizes an additional diagnostic approach to questionable hips. It represents already a new therapeutic approach in hip chondromatosis.
