The purpose of this study was to compare the biomechanical properties of a novel wrap around tendon repair method with those of the standard Pulvertaft technique used for tendon reconstructions. Seventy-two porcine extensor tendons were used to create 36 reconstructions in six sets of six repairs, each using one of the two surgical techniques with differing lengths of the reconstructions. All the reconstructions were tested in vitro by cyclic tensile loading, resulting in the time-zero strength. When only the size of the repair and the strength were compared, and length of the reconstruction was not taken in consideration, the 'wrap around' reconstructions were of similar strength but less bulky than the Pulvertaft repairs. In conclusion, the 'wrap around' technique gives a thinner reconstruction which is as strong as, or stronger than the Pulvertaft technique, depending on the amount of weaves.
本研究的目的是比较一种新型环绕式肌腱修复方法与用于肌腱重建的标准普尔弗塔夫特技术的生物力学特性。使用72根猪伸肌腱进行6组修复，每组6次重建，每次重建使用两种手术技术之一，重建长度不同。所有重建均在体外通过循环拉伸加载进行测试，得出零时强度。当仅比较修复尺寸和强度，而不考虑重建长度时，“环绕式”重建的强度相似，但比普尔弗塔夫特修复更小巧。总之，“环绕式”技术可实现更细的重建，根据编织数量，其强度与普尔弗塔夫特技术相同或更强。
