In an attempt to produce necrosis of the femoral head, the medial femoral circumflex vessels were disrupted in 13 normal piglet hips through a medial approach. Femoral heads were recovered 3-6 months (average 4.2 months) postoperatively. None of these hips showed gross, radiographic, or microscopic evidence of necrosis. This demonstrates that necrosis, which may occur after the medial approach in the hip of a child, is not due to the direct damage to the medial femoral circumflex vessels.
为了造成股骨头坏死，通过内侧入路破坏了13只正常仔猪髋关节的旋股内侧血管。术后3 - 6个月（平均4.2个月）取出股骨头。这些髋关节均未显示出坏死的大体、影像学或显微镜下证据。这表明儿童髋关节内侧入路后可能发生的坏死并非由于旋股内侧血管的直接损伤所致。
