【摘要】 目的 比较三种肌腱周边缝合方法，即连续法、Cross- Stitch法和Halsted法的生物力学特性。 方法 将60只新鲜成年猪后蹄Ⅱ区趾屈肌腱造成切割伤，按手术先后随机分成6组，每组10只。第1 ～ 3组用Kessler法进行核心缝合，第4 ～ 6组用Tang法进行核心缝合。各组均加用周边缝合修复腱周：第1、4组用连续缝合法，第2、5组用Cross- Stitch法，第3、6组用Halsted法。术后即刻应用材料力学测定仪测定修复肌腱被拉伸至出现2 mm间隙时，其2mm间隙形成负荷及最大负荷；并根据位移 -负荷曲线计算其刚度及最大功耗。 结果 同一核心缝合法时，Halsted法的2- mm间隙形成负荷、最大负荷、最大功耗最高；Cross - stitch法次之；连续缝合法最低。Halsted法的刚度与Cross - stitch法相近而连续法较差。 结论 Halsted周边缝合法对肌腱抗张能力的作用最大，能够满足肌腱手术后早期活动所需的抗张力要求。

【 Abstract】 Objective To compare the biomechanical characteristics of threeperipheral suture techniques which are named running, cross - stitch, and Halsted. Methods Sixty pig - toe flexorprofundus tendons were divided into 6 groups. Each group of tendons were transected inzone Ⅱ , and were ndmaximum energy consumption were highest for the Halsted peripheral suture technique,secondly for the cross - stitch suture, and lowest for running suture. Halsted peripheralsuture was similar to cross - stitch peripheral suture in stiffness. Conclusions Halsted peripheralsuture was recommended for clinical repair of flexor tendons while early mobilizationprotocol was considered because it can offer great tensile strength and good interface.
