伞式经跟骨缝合组合修复跟腱断裂的实验研究

目的 评价伞式经跟骨组合缝合法修复跟腱断裂的生物力学特性。方法 采用伞式经跟骨缝合法，组合应用0-薇乔线(Poliglactin-910)、腱周采用交叉缝合法修复8只家兔单侧跟腱断裂模型，术后固定3天，功能锻炼25天后行离体生物力学实验。结果术后28天组达正常组跟腱生物力学特性的90％。结论 采用伞式经跟骨组合缝合法修复跟腱允许早期康复活动，早期功能锻炼可以迅速提高跟腱的生物力学特性。

A Biomechanical in vitro Study of Parachute-Like and Through-Calcaneus Suture Combination for the Repair of Rabbit Achilles Tendon Rupture

Objective To evaluate the mechanical property of a new parachute-like and through-calcaneus suture combination technique for the repair of Achilles tendon rupture. Methods Eight Achilles tendons each respectively from eight New Zealand white rabbits were repaired by a new suture technique which combined the end-to-end suture method with 0/0 Poliglactin-910 and the cross-stitch epitenon suture method with 5/0 Poliglactin-910. After the suture, the rabbits were given 3-day immobilization cast and then 25 days of functional practice. The in vitro experimental study was conducted next. Results The experimental group achieved 90% of the biomechanical property of the intact group. Conclusion The tendon repair of the new combinatory technique allows early-mobilization which in turn improves the mechanical property of the repaired Achilles tendons.
