Suture Anchor Arthroplasty for Thumb Carpometacarpal Osteoarthritis

Abstract

We describe a surgical technique for the treatment of thumb carpometacarpal joint osteoarthritis that we call suture anchor arthroplasty. This technique is similar to ligament reconstruction tendon interposition arthroplasty except that the entire flexor carpi radialis tendon is secured to the thumb metacarpal base by using suture anchors instead of a bone tunnel. The use of suture anchors eliminates the need for a transosseous bone tunnel, simplifying the procedure.
