背景股骨头坏死（ONFH）的分类系统是基于坏死病灶的大小、体积和位置。股骨头坏死常常导致股骨头塌陷。由于髋臼覆盖与股骨头上的机械应力相关，因此也可能与ONFH患者的股骨头塌陷相关。然而，这些患者髋臼覆盖和股骨头塌陷之间的相关性尚未确定。
BackgroundOsteonecrosis of the femoral head (ONFH) classification systems are based on the size, volume, and location of necrotic lesions. Often—but not always—ONFH results in femoral head collapse. Because acetabular coverage is associated with mechanical stress on the femoral head, it might also be associated with femoral head collapse in patients with ONFH. However, the association between acetabular coverage and femoral head collapse in these patients has not been established.
