The purpose of this study was to examine the in vivo characteristics of the stainless-steel Teno Fix device used for flexor tendon repair. The common flexor digitorum superficialis tendon was transected in 16 dogs and repaired with the device. The animals were euthanized at 3, 6, or 12 weeks postoperatively. Difficulties with cast immobilization led nine of 16 animals to be full weight bearing too early, leading to rupture of their repairs. The seven tendons with successful primary repairs (gap <2mm) underwent histological examination. This in vivo study demonstrates that use of the Teno Fix in "suture" of dog flexor tendons did not lead to scarring at the tendon surface, does not cause an inflammatory reaction within the tendon and does not interfere with tendon healing.
本研究的目的是检查用于修复屈指肌腱的不锈钢Teno Fix装置的体内特性。在16只犬中切断指浅屈肌腱并用该装置进行修复。术后3、6或12周对动物实施安乐死。由于石膏固定困难，16只动物中有9只因过早完全负重导致修复处断裂。对7条初次修复成功（间隙<2mm）的肌腱进行了组织学检查。这项体内研究表明，在犬屈指肌腱“缝合”中使用Teno Fix不会导致肌腱表面瘢痕形成，不会在肌腱内引起炎症反应，也不会干扰肌腱愈合。
