Fig. 3From: Bunnell or cross-lock Bunnell suture for tendon repair? Defining the biomechanical role of suture pretensionFluoroscopic examination of the suture failure mechanism. Different tension loads were applied to the Bunnell and cross-lock techniques. Suture cut out occurred at lower tension levels in the Bunnell technique, which may explain the lower resistance to gap formationBack to article page
