Abstract

We performed an experimental study to evaluate the mechanical properties of polyvinylidene fluoride sutures and to compare their use with that of standard polypropylene sutures for the circumferential, epitendinous suture of a flexor tendon repair. Polyvinylidene fluoride sutures had a smaller suture diameter, a greater knot pull strength and less delayed extension when under creep testing, than polypropylene sutures. Tendons repaired using polyvinylidene fluoride sutures had significantly greater gap and breaking strengths than those repaired using polypropylene sutures.

摘要

我们进行了一项实验研究，以评估聚偏二氟乙烯缝线的力学性能，并将其与标准聚丙烯缝线用于屈肌腱修复的环周、腱外膜缝合时的情况进行比较。与聚丙烯缝线相比，聚偏二氟乙烯缝线的缝线直径更小，在蠕变测试下的结拉力更大且延迟延伸更小。使用聚偏二氟乙烯缝线修复的肌腱比使用聚丙烯缝线修复的肌腱具有显著更高的间隙强度和断裂强度。
