【摘要】 目的 为探索Ⅱd区不同伤情下肌腱的合理修复方法,进行动物实验,以提供对临床有用的参考依据。方法 选用正常白色来亨鸡24只,每组12只24趾。A组为单纯切割伤组,左侧修复双腱,右侧切除浅腱修复深腱;B组为严重挫伤组,修复同前。直接关闭腱鞘,术后3周控制性主、被动活动,术后6周进行修复的屈趾深肌腱的生物力学测定(滑动距离、屈曲功),并观察和测量各修复组织间的粘连性状和粘连面积。结果 单纯切割伤组两种修复方法之间的滑动距离、屈曲功、粘连性状和粘连面积在统计学上没有显著差异;而在严重挫伤组,双腱修复侧的滑动距离小于浅腱切除单纯修复深腱侧,屈曲功和粘连面积大于单纯修复深腱侧,粘连程度较大,在统计学上有显著性差异(p<0.05)。结论 本研究提示:临床上对Ⅱd亚区的浅、深屈趾肌腱单纯切割伤,应修复双腱;严重挫伤时,则应切除浅腱而只修复深腱。更多还原

【Abstract】 Objective The purpose of this study was to evaluate methods of primary repair of flexor tendon in zone II d morphologically and biomechanically. Methods Twenty-four white Leghorn chickens were divided into 2 groups. The long toes of each side were assigned for following procedures separately: (1) Group A: On the left side, the FDS and FDP tendons in zone II d were repaired after tendon transection. On the right side, only the FDP tendon was repaired. (2) Group B: The FDS and FDP tendons were transected with the epitenon and tendon gliding floor damaged. Tendon repair was the same as in the group A. Six weeks later, tendon excursion, work of flexion of the toe and extent of adhesion were evaluated. Results In the group A, there were no significant differences between the two experimental sides. In the group B, excursion of the FDP tendon on the left side was less than that on the right side, and work of flexion of the toe and extent of adhesion on the left side were larger than that on the right side significantly (p < 0.05) . Conclusion This ex-periment demonstrated that the FDS and FDP tendons in zone II d should be repaired after they were transect-ed , and when severe injuries of the tendons presented, the FDP tendon should be repaired with the FDS ten-don partially resected.更多还原
