The relationship between pregnancy and femoral head necrosis

Abstract

Reported cases of avascular necrosis of the head of the femur associated with pregnancy are rare. Two further cases are presented, and a review of the previously reported cases suggests that other known predisposing causes of avascular necrosis may be incriminated in the aetiology. The possibility that a normal pregnancy may very rarely be associated with avascular necrosis is suggested by one of our patients and receives some support from the previously reported cases.
