Weilby Technique for Interpositional Arthroplasty of Thumb Carpometacarpal Joint

Thumb interposition is an accepted technique for the treatment of stage 2-4 arthritis of the trapeziometacarpal joint of the thumb. With the usage of the Weilby suspension technique, the flexor carpi radialis is used to suspend the thumb metacarpal using an intertendinous weave rather than bony tunnels. This method allows early range of motion and decreased splint usage, maximizing outcomes, and recovery.
