Differences between locking loops and grasping loops: effects on 2-strand core suture.
Abstract
The differences between locking and grasping configurations used to suture lacerated flexor tendons were evaluated using a 2-strand core model in human cadaver tendon. Locking suture configurations tighten around bundles of tendon fibers with tension, while grasping loops do not tighten around but pull through tendon fibers and distract with tension. The greatest tensile strength was found in 1-locking, 2-locking, and 2-grasping suture loop configurations per suture strand. The 2-grasping loops per suture strand, however, had the greatest distraction (gapping) as the suture material pulled through the tendon. A single locking configuration per strand yielded the maximum tensile strength with reduced distraction (gapping) at the repair site.
