Suture Tape Augmentation of the Thumb Ulnar Collateral Ligament Repair: A Biomechanical Study
Abstract; Purpose: This study aimed to evaluate and compare the biomechanical strength of repair of the thumb ulnar collateral ligament (UCL) alone and repair augmented with suture tape.
Methods: Twelve fresh-frozen cadaveric specimens (6 matched pairs) had the UCL divided at its attachment on the base of the proximal phalanx and repaired with or without suture tape augmentation. A material testing machine was used to provide valgus stress at a rate of 0.1 mm/s until failure. The maximum load, load at clinical failure, and mode of failure were recorded…..
