大腿骨頭壊死に続発した大腿骨頚部内側骨折の2例

抄録

Femoral neck fracture following aseptic necrosis of the femoral head is rarely reported. We have experienced two such cases and reported here. Histologically, the extracted femoral head had wide necrotic area with process of bone resorption and formation being present partially. The mechanism of the fracture was suggested that the widened necrosis of the femoral head caused physical stress upon the cervical region resulting in fracture.
