Abstract:

目的 通过生物力学测试探讨骨锚技术修复深层尺桡韧带于尺骨凹对于恢复远侧尺桡关节旋转稳定性的重要性,为选择手术方法提供生物力学理论依据。 方法 取 9 具新鲜成年尸体上肢标本,按照完整标本(正常组)、深层尺桡韧带损伤(损伤组)、螺钉固定并肌腱缝线缝合修复深层尺桡韧带(修复组)顺序制备模型后,采用 AG-IS 系列 MS 型生物力学测试系统,分别于腕关节背伸 45°、中立位及屈曲 45° 进行内、外旋生物力学测试,测量其扭矩。统计分析比较各组内、外旋扭矩差异。 结果 腕关节背伸 45°、中立位及屈曲 45° 时,正常组内旋扭矩分别为(0.83±0.33)、(0.86±0.34)、(0.36±0.30)N·m,外旋扭矩分别为(0.86±0.38)、(0.44±0.22)、(0.25±0.21)N·m;损伤组内旋扭矩分别为(0.18±0.17)、(0.22±0.17)、(0.16±0.15)N·m,外旋扭矩分别为(0.27±0.26)、(0.13±0.17)、(0.04±0.04)N·m;修复组内旋扭矩分别为(0.79±0.34)、(0.73±0.33)、(0.41±0.23)N·m,外旋扭矩分别为(0.80±0.39)、(0.41±0.22)、(0.41±0.40)N·m。腕关节背伸 45°、中立位及屈曲 45° 时,损伤组内、外旋扭矩显著低于正常组和修复组,差异均有统计学意义(P<0.05); 3种位置下修复组内、外旋扭矩与正常组比较差异均无统计学意义(P>0.05)。 结论 深层尺桡韧带是维持远侧尺桡关节旋转稳定性的重要结构,骨锚技术修复深层尺桡韧带于尺骨凹止点,对于恢复远侧尺桡关节旋转稳定性有着重要意义
