Suture Anchor Arthroplasty for Thumb Carpometacarpal Osteoarthritis
Abstract
To describe a technique termed Suture Anchor Arthroplasty' (SAA), for thumb carpometacarpal joint osteoarthritis and to report the clinical results. SAA is a surgical technique similar to Ligament Reconstruction Tendon Interposition' (LRTI) Arthroplasty, except that the entire flexor carpi radialis tendon is secured to the thumb metacarpal base using suture anchors instead of a bone tunnel. Temporary pin fixation is not used. Seventeen consecutive patients (20 hands) underwent SAA. Patients were assessed with a standardized questionnaire, physical exam, and x-rays at most recent follow-up. At an average follow-up period of 24 months (range 7-74 months), all patients had excellent pain relief. All patients were satisfied with 15 being very satisfied and 2 somewhat satisfied. All patients would have the surgery again if given the choice. Grip strength improved by 68% and key pinch strength increased by 35% compared to preoperative values. Loss of the trapezial space height averaged 28% by radiographs. No suture anchors pulled out and no patients required reoperation.
