Effect of suture size on locking and grasping flexor tendon repair techniques.
An experimental study was performed using human cadaver flexor tendons to investigate the effect of locking and grasping loop techniques on the tensile properties of repaired flexor tendons, which closely resemble the clinical model. Statistically significant improvement was observed only with the locking loop technique for ultimate and gap strength values using 2-0 core suture and ultimate strength values using 3-0 core suture. There was no statistically significant increase in tensile strength values using 4-0 core suture material. A heavier core suture used with the locking loop technique provided greater ultimate and gap strength of a repaired tendon than when used with the grasping loop technique.
