Abstract
Objective To compare tensile strength of four different modified Kessler flexor tendon suture techniques. Methods Forty flexor digitorum profundus tendons of white pig hind limbs were transected and repaired using 4 suture techniques, with 10 tendons for each technique. The four suture techniques were Kessler, Double Kessler, Running suture and Kessler plus Running suture. After suturing, 2 mm gap formation force and failure load of the sutures were tested. One-way ANOVA was applied for statistic comparison of each technique. Results Double Kessler suture technique has the greatest tensile strength with its failure load, fonowed by Kessler plus Running suture, Kessler and Running suture. Kessler plus Running suture method had the greatest 2 mm gap formation force, followed by Double Kessler, Running suture and Kessler technique. Conclusion Kessler plus Running suture can better endure early finger active mobilization. Key words: Tendon injuries; Suture techniques; Biomechanics
