Arthroscopic Management of Thumb Carpometacarpal Joint Arthritis and Pathology.

Abstract

Basilar thumb arthritis is a debilitating condition characterized by pain, reduced joint stability, and reduced capacity for daily activities. Various arthroscopic approaches have been described based on patient factors, as well as radiographic and arthroscopic staging criteria. Here we provide an overview of arthroscopic management of basilar thumb arthritis, including patient evaluation, surgical techniques, outcomes, and new developments. We describe our preferred approach for Eaton stage I-III disease, consisting of arthroscopic hemitrapeziectomy with suture button suspensionplasty. This technique is safe, reliable, and allows for early range of motion and quicker recovery while minimizing scarring and reducing the risk of nerve injury.
