Suture Suspensionplasty Compared With Ligament Reconstruction and Tendon Interposition for Surgical Treatment of Thumb Carpometacarpal Arthritis.

Purpose: Thumb carpometacarpal (CMC) arthritis is the most common arthritis of the hand, with most studies demonstrating little difference in outcomes between various surgical treatment techniques. However, trapeziectomy, followed by ligament reconstruction and tendon interposition (LRTI), remains the technique of choice among hand surgeons in the United States. In 2009, suture suspensionplasty (SS) was first described as a less invasive alternative to LRTI.
