Abstract
In performing the flexor tendon repair, peripheral suture is essential to improve the sufficient strength and to accomplish the early active mobilization of repaired flexor tendons. However, because there is soft tissue around the flexor tendon, full circumferential peripheral suture surgery is time-consuming, be a burden to the patient. Therefore, one-half technique is realistic method. The purpose of this study was to evaluate about partial interlocking cross-stitch peripheral suture under cyclic loading conditions. Artificial rolls, ParotisrollsTM were used as the experimental model in this study. All pairs of the artificial roll tendon model were sutured using the 6-strand Kessler core suture with 4-0 Polypropylene. One-half or third-fourths circumferential interlocking cross-stitch, or full circumferential peripheral suture techniques were performed using 6-0 Polypropylene. An initial cyclic load of 10 [N] for 500 cycles was applied and increased by 5 [N] for an additional 500 cycles at each new load until rupture. In result, strength of third-fourths circumferential interlocking cross-stitch suture is almost equal to full circumferential peripheral suture. Additionally, we designed the combined suture by using the interlocking cross-stitch at the palmar three-fourths side, and by using running suture at the dorsal one-fourths side. This study was considered to be effective in groping for suture method.
