Pigmented villonodular synovitis of the hip joint (review of the literature and report of personal case material).

The authors illustrate the diagnostic and therapeutic problems posed by pigmented villonodular synovitis of the hip by reviewing the literature and reporting on six original cases. Four of these cases were treated by synovectomy and two by prostheses. The best results were obtained with the total prostheses, but this must be considered in the light of the fact that most of the patients were young.
