APL Lasso Suspensionplasty for Trapeziectomy

Base of thumb arthritis is a common pathology, with late-stage disease often treated by trapeziectomy and a form of ligament reconstruction or suspension. No therapeutic option for suspension or ligament reconstruction has proven to be superior to others, with risks inherent to all. Here, the authors describe a novel technique utilizing an accessory slip of abductor pollicis longus looped around the second metacarpal base to suspend the metacarpal and prevent subsidence after trapeziectomy. This technique aims to mitigate some of the risks seen in other methods, while providing similar biomechanical strength. Early clinical results are also presented.
