摘要
目的 观察肘关节尺侧副韧带(UCL)的形态特征,对横束(TB)划分解剖学类型,为肘关节韧带的外科诊治,提供基础资料.方法 71例结构完整的人上肢标本,解剖并观察TB的形态特征及变异,依据其与前束(AB)的关系划分类型;分别测量AB与TB的长度、起点宽度、止点宽度等.结果 (1)根据TB与AB纤维的融合方式分为:①I型:TB的末端与AB远侧半融合,二者纤维呈"L"型45例;②Ⅱ型:TB的末端与AB的纤维呈弧形融合26例.(2)与男性相比,Ⅱ型更多地出现在女性,两性在类型构成上差异有统计学意义(P＜0.05).男性与女性AB的长度分别是(31.27±6.22)mm、(26.61±3.40)mm,差异有统计学意义(P＜0.05).结论 对于TB的分型是对UCL解剖结构的重要补充;TB与AB的融合以I型为主,TB协助AB、PB共同维持肘关节稳定.
Abstract
Objective To investigate the morphological characteristics of the transverse bundle(TB)of the ulnar collateral ligament of the elbow joint.Methods 71 adult elbow joints were dissected and the anatomic fea-tures of the TB were noted.The lengths,widths of the origins and insertions of the AB and TB were measured with a digital vernier caliber.Results(1)The TB was divided into two types according to the relation with AB:① type I,the TB was continued to the distal half with the AB in 45 cases.② type Ⅱ,the TB was continued to the entire AB in 26 cases,which was significantly more frequently observed in females than those of males(P＜0.05).(2)There was a significant difference in length of AB between male and female(P＜0.05).Conclusions The TB fre-quently continues to the distal half of the AB,which may have important implications for the surgical reconstruction of elbow ligaments.
