[Rapidly destructive coxarthrosis: case study and literature review].

Rapidly destructive coxarthrosis is a rather rare disease that affects most frequently women between 60 and 66 years. This bone disease is defined by a rapid chondrolysis with total obliteration of the joint space in the superolateral segment of the joint in an average period of one year, followed by rapid bone destruction of the femoral head and the roof of the acetabulum. This periarticular osteolysis causes a rising of the femoral head. The radiographic appearance shows minimal osteophytosis but this is never absent. The study of follow-up radiographs is helpful to make a choice in the differential diagnosis among the ethiologies of a rapidly destructive hip.
