2.2 两组强度的比较 载荷1 200 N时,两组股骨转子间骨折内外侧的应力强度,实验组分别为(6.44±0.55),(6.72± 0.57) MPa,对照组分别为(3.03±0.27),(2.89±0.26) MPa,实验组比对照组分别高56%和57%,统计显示差异有显著性意义(t=3.378,P < 0.05)。 2.3 两组刚度的比较 分为股骨的轴向刚度和水平剪切刚度,实验组分别为(701.75±63.13) N/mm和(1 935.48± 164.45) N/mm,而对照组分别为(487.81±41.46) N/mm和(1 463.42±131.72) N/mm,两组比较,轴向刚度相差30%,水平剪切刚度相差24%,统计显示差异均有显著性意义(t=3.124,P < 0.05)。 2.4 两组扭转力学性能的比较 将标本近端股骨头包埋固定使股骨颈与扭转机的转轴在一直线,远端以可调夹具置于扭转力学实验机上,以0.032 (°)/s速度顺时针匀速增加扭转力,记录扭角大小。采用可灌注骨水泥动力髋螺钉系统固定股骨转子间骨折的扭矩,在扭角为3°时为(6.69±0.62) N·m,而常规动力髋螺钉系统的扭矩为(5.14±0.48) N·m,两者相差23%,差异有显著性意义(t=2.786,P < 0.05),见表1。 "
2.5 两组失效载荷的比较 按照Joseph等[28]的骨折固定失效判定标准:①大转子顶骨折断端皮质固定两点位移≥ 5 mm。②变形逐渐增加而负荷不增加甚至下降。③拉力螺钉后退超过10 mm。④主钉尖穿出股骨头。出现其中任何一种情况认为此时为固定的失效载荷。实验组动力髋螺钉固定能承受最大载荷为(3 680±274) N,相对位移(9.10± 0.88) mm;而对照组动力髋螺钉承受最大载荷为(3 244± 262) N,相对位移(8.23±0.74) mm,实验组强度高出对照组12%(t=2.654,P < 0.05),见表2。 从破坏形式来看,60%破坏发生在骨折处产生切割破坏,位移≥ 5 mm,转子间弯曲破坏占30%,只有10%主钉穿出股骨头。"
