The intramedullary pressure of head center and load area were higher than that of trochanter major and femoral neck at stage ⅰ and ⅱ .

Ⅰ、Ⅱ期股骨头缺血性坏死股骨头中心、股骨头负重区压力明显高于 大 粗 隆及股骨颈；

Body surface mark and measurement about femoral head center spina iliaca anterior superior femoral trochanter major patella apical and ankle 's middle point have been made in thirty healthy adults .

对30名健康成年人进行了股骨头中点、髂前上棘、股骨 粗 隆 尖点、髌骨下极、踝关节中点的体表标记和测量。

Conclusions : The mode of operation influences prognosis and greater trochanter arc incision is superior to minor incision straight incision or S major incision . The follow up results are satisfactory .

结论：手术方式影响预后，经临床应用，大 转子上 后方弧形切口优于小切口、直切口、S形 大切口，随访结果满意。

Results The order of the intramedullary pressure of healthy person was : trochanter major load area .

结果健康人 股骨近端骨髓腔内压力， 股骨 大 粗 隆 < 股骨颈 <股骨头 中心 <股骨头负重区。
