Abstract目的确定在股骨假体柄尾端位于股骨螺钉孔水平时对股骨干扭转力学特性的影响.方法将配对的15对新鲜冷冻羊股骨随机分为三组,每组5对,在每只右侧股骨的近端外侧制作出单皮质的骨缺损(10%股骨干直径),左侧为完整骨.A组为制作出骨皮质螺钉孔后,股骨髓内不放置假体柄;B组为股骨假体柄尾端位于骨缺损水平;C组为股骨假体柄尾端位于骨缺损远端2倍股骨干直径处.将股骨两端固定在力学机上,近端内旋1°/s直至骨折,记录最大扭矩及最大旋转角度.配对t检验计算出各配对骨间是否有统计学差异,另外将5对完整骨作为对照组.结果A组最大扭矩:左侧(41.10±8.16)N·m,右侧(37.95±8.73)N·m;最大旋转角度:左侧13.62°±0.82°,右侧13.31°±1.74°.B组最大扭矩:左侧(44.49±9.93)N·m,右侧(43.98±6.00)N·m;最大旋转角度:左侧11.08°±1.30°,右侧11.23°±0.83°.C组最大扭矩:左侧(43.83±7.62)N·m,右侧(41.58±12.94)N·m;最大旋转角度:左侧12.35°±1.27°,右侧13.08°±5.56°.对照组最大扭矩:左侧(39.56±24.64)N·m,右侧(33.59±18.47)N·m;最大旋转角度:左侧14.84°±5.42°,右侧11.80°±3.04°.左右两侧对比差异均无统计学意义(P>0.05).结论股骨柄尾端位於螺釘孔水平不降低股骨幹的最大扭轉力。
