Abstract:
Rapidly destructive hip disease is a rare condition, the cause of which is yet to be clarified, and is described in the literature by scant case reports. The disease was first described by Forestier in 1957, and since then many names have been proposed to describe the rapid vanishing of the femoral head, and occasionally the acetabulum. This condition initially represents as acute hip pain, and rapidly progresses to complete vanishing of the proximal femur, within a few months. We briefly discuss the literature regarding this phenomenon, and describe a case of a female patient who suffered from complete disappearance of the femoral head within 9 weeks.
