Lee YK, Yoo JJ, Koo KH, Yoon KS, Min BW, Kim HJ Collapsed subchondral fatigue fracture of the femoral head. [Comparative Study, Journal Article, Research Support, Non-U.S. Gov't] Orthop Clin North Am 2009 Apr; 40(2):259-65.
Several etiologies can lead to a subchondral fracture of the femoral head, which may result in femoral head collapse and degenerative change. This article evaluates the follow-up results of subchondral fatigue fractures of the femoral head in which femoral head collapse occurred. The study shows that collapsed subchondral fatigue fractures of the femoral head have a benign clinical course quite unlike that of collapsed osteonecrosis of the femoral head.
