Technique for Single-Graft Lateral Ankle Stabilization: A Cadaveric Biomechanical Study

摘要

Several surgical procedures have been described for treatment of lateral ankle instability with varying degrees of success and complications. The purpose of this study was to describe a modification to the Bréstrom procedure that allows for repair when lateral soft tissues are insufficient for primary repair. Cadaveric specimens were tested in a Telos Stress Device with lateral ligaments intact, transected, and with a single-graft repair. Talar tilt angle and anterior displacement index were measured and compared between each phase of the study. There was no significant difference between talar tilt angle of specimens with ligaments intact and ligaments grafted (p = .2295). There was no significant difference between anterior displacement index of specimens with ligaments intact and ligaments grafted (p= .6482). A cadaveric model is used to demonstrate that lateral ankle ligaments can be repaired using a new single-graft technique, and is comparable to pre- sectioned intact lateral ankle ligaments.
