Abstract: Purpose: Multiple methods of ligament reconstruction and tendon interposition (LRTI) or suspension have been described to prevent first metacarpal subsidence following trapeziectomy. An abductor pollicis longus (APL) lasso is a newly described technique of suspensionplasty, which aims to obviate concerns regarding previously described methods. The purpose of this study was to compare subsidence between the APL lasso and 2 other common methods, APL sling and flexor carpi radialis LRTI, after trapeziectomy in cadaveric forearms. Methods: Ten cadaveric forearms were prepared on a custom-made plinth to recreate pinch grip upon the loading of previously identified muscles. A sequence of procedures was performed, with radiographs taken after each to assess the subsidence. Results: The APL lasso was superior to simple trapeziectomy and flexor carpi radialis LRTI in preventing subsidence. Conclusions: The APL lasso was superior to simple trapeziectomy and flexor carpi radialis LRTI in preventing subsidence, and it may be a viable alternative when considering suspension methods after trapeziectomy. Clinical relevance: The APL lasso may be considered when trying to prevent subsidence after trapeziectomy.
