研究了涤纶肌腱夹板修复人体深肌腱损伤部位的机械强度；夹板放置在背表面和肌腱物质内部。比较改良的Kessler、Becker和Savage修复技术。Kessler的极限抗拉强度为2.55 kgf， Becker为3.00 kgf， Savage为8.29 kgf，内腱夹板为8.46 kgf，背腱夹板为8.10 kgf；Savage和两种肌腱夹板技术的抗拉强度明显高于Kessler和Becker。Kessler的间隙强度为1.44 kgf， Becker为2.22 kgf， Savage为2.45 kgf，内腱夹板为2.05 kgf，背腱夹板为3.15 kgf。背腱夹板技术的间隙强度明显高于其他技术。在这些技术的循环测试中，差距的大小没有显著差异；然而，Kessler的七次修复中有三次失败，Becker的六次修复中有一次失败。这些尸体研究的结果表明，这两种肌腱夹板修复技术都与Savage相当，并且可能具有足够的强度，可以在最小阻力的情况下进行术后主动运动。进一步的体内试验正在进行中。
Mechanical strength of tendon repair using Dacron tendon splints across the laceration site were evaluated in human cadaver profundus tendons; the splints were placed both on the dorsal surface and internally within the tendon substance. Comparison was made to modified Kessler, Becker, and Savage repair techniques. Ultimate tensile strength was 2.55 kgf for the Kessler, 3.00 kgf for the Becker, 8.29 kgf for the Savage, 8.46 kgf for the internal tendon splint, and 8.10 kgf for the dorsal tendon splint; the Savage and both Tendon Splints techniques had significant higher tensile strength than the Kessler and Becker. Gap strength was 1.44 kgf for the Kessler, 2.22 kgf for the Becker, 2.45 kgf for the Savage, 2.05 kgf for internal tendon splint, and 3.15 kgf for the dorsal tendon splint. The dorsal tendon splint technique showed significant greater gap strength than the other tour techniques. There was no significant difference in the magnitude of the gap during cyclic testing of these techniques; however, three of seven Kessler repairs failed and one of six Becker repairs failed. The results of these cadaver studies suggest that both tendon splint repair techniques are comparable to the Savage and may have sufficient strength to allow postoperative active motion against minimal resistance. Further in vivo testing is in order.
