Thumb Carpometacarpal Suspension Arthroplasty With Flexor Carpi Radialis Ligament Reconstruction and Tendon Interposition Using An Absorbable Interference Screw: A Volar Approach Technique.

The goal of operative intervention for pantrapezial arthritis is to relieve pain, maintain or improve motion, stability, and strength, and restore function. The purpose of this article is to present a volar approach to thumb carpometacarpal suspension arthroplasty using an absorbable interference screw for flexor carpi radialis ligament reconstruction and tendon interposition in the treatment of pantrapezial arthritis. This technique allows for visualization of the volar beak and avoidance of the radial artery and the branches of the superficial radial nerve while allowing optimal surgical manipulation for suspensionplasty with interference screw fixation and tendon interposition at the carpometacarpal joint.
