Abstract:

目的探讨锁定重建钢板行髋臼横行后壁骨折内固定的生物力学稳定性,为其临床应用提供生物力学依据。 方法取8具(16个)成人尸体髋臼标本,制备髋臼横行后壁骨折模型;根据随机数字表法分为两组,每组8个标本。实验组采用10孔后柱锁定重建钢板固定,对照组采用10孔后柱重建钢板联合前柱拉力螺钉及后壁螺钉固定。应用生物力学试验机对标本加载至供体体质量的5/6,加载速度15 N/s,计算加载时间并进行垂直加载。通过光栅位移传感器记录四边体内侧横向、骨折端纵向及后壁骨折块位移,比较两组生物力学稳定性。 结果实验组四边体内侧横向位移为(1.99±0.32)mm,大于对照组的(1.75±0.22)mm,比较差异无统计学意义(t=-1.735,P=0.105)。实验组骨折端纵向位移及后壁骨折块位移分别为(1.56±049)、(0.86±0.33)mm,均小于对照组的(1.64±0.51)、(1.01±0.35)mm,但组间比较差异亦无统计学意义(t=0.293,P=0.772;t=1.516,P=0.154)。 结论对于髋臼横行后壁骨折,应用锁定重建钢板内固定能提供足够的生物力学稳定性,同时避免了拉力螺钉的使用,显著降低了螺钉植入关节的风险
