A notch-like defect at the vertex of the proximal femoral ossification center is a normal variant in children. This has often been mistaken for Legg-Perthes disease. This sharply defined defect is distinct from the irregular epiphyseal ossification patterns common in other areas.
股骨近端骨化中心顶点处的缺口样缺损在儿童中是一种正常变异。这常常被误诊为Legg-Perthes病。这种边界清晰的缺损与其他部位常见的不规则骨骺骨化模式不同。
