摘要 背景:尺骨茎突骨折常伴发于桡骨远端骨折。本研究的目的是确定桡骨远端骨折牢固内固定后伴发的尺骨茎突骨折对腕关节功能或远期下尺桡关节不稳定的发展是否有影响。方法:138例不稳定的桡骨远端骨折手术治疗病例纳入本研究。手术过程中伴发的尺骨茎突骨折未进行内固定。患者尺骨茎突骨折被分为未骨折组、非基底部骨折组和基底部骨折组,根据受伤时尺骨茎突骨折移位程度分为未骨折组、轻度移位组(≤2mm)和明显移位组(〉2mm)。术后评估包括握力和腕关节活动范围的测量;改良Mayo腕关节评分和臂、肩、手不稳定(DASH)评分系统,以及在平均术后19个月的测试下尺桡关节的不稳定。结果:138例中76例(55%)存在尺骨茎突骨折。47例(62%)为尺骨茎突非基底部骨折,29例(38%)为尺骨茎突基底部骨折。34例(45%)轻度移位,42例(55%)明显移位(〉2mm)。我们没有发现尺骨茎突骨折位置或移位程度与腕关节功能有显著相关性。2例腕关节(1.4%)出现下尺桡关节慢性不稳。结论:桡骨远端骨折稳定内固定后伴发的尺骨茎突骨折对腕关节功能或下尺桡关节的稳定性没有明显的不利影响。
