In performing the flexor digital tendon repair, peripheral suture is essential to improve the sufficient strength and to accomplish the early active mobilization of repaired flexor tendons. The purpose of this study was to evaluate unrepaired site about partial interlocking cross-stitch peripheral suture under cyclic loading conditions. Artificial rolls, called ParotisrollsTM were used as the experimental model in this study. Halfway or third-fourths circumferential interlocking cross-stitch, or complete 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 complete circumferential peripheral suture.
