ABSTRACT
PURPOSE:
In this study, we compared the Tang repair technique with the 6-strand modified Lim-Tsai repair technique under cyclic testing conditions.METHODS:
Twenty fresh-frozen porcine flexor tendons were randomized into 2 groups for repair with either the modified Lim-Tsai or the Tang technique using Supramid 4-0 core sutures and Ethilon 6-0 epitendinous running suture. The repaired tendons were subjected to 2 stage cyclic loading. The survival rate and gap formation at the repair site were recorded.RESULTS:
Tendons repaired by the Tang technique achieved an 80% survival rate. None of the modified Lim-Tsai repairs survived. The mean gap formed at the end of 1000 cycles was 1.09 mm in the Tang repairs compared with 4.15 mm in the modified Lim-Tsai repairs.CONCLUSIONS:
The Tang repair is biomechanically stronger than the modified Lim-Tsai repair under cyclic loading. CLINICAL RELEVANCE The Tang repair technique may exhibit a higher tolerance for active mobilization after surgery with less propensity for gap formation.Palabras clave
