Abstract:
Objective This study was designed to evaluate the biomechanical properties in tendons across the joints when Palmar or dorsal stitches were used. Methods Twenty porcine tendons were transected and then repaired in zone Ⅱand divided into two groups,using modified Kessler by placing the stitches in volar or dorsal part of tendons.The repaired tendons were placed on a joint model with flexion of 60?. An instron tensile testing machine was used to investigate 2 mm gap formation force and ultimate tensile strength. Results 2 mm gap formation force and ultimate tensile strength were both higher when dorsal placement of stitches was used. Conclusions Dorsal placement of stitches was recommended for repairing the tendons across the joints because it can offer greater tensile strength.
