    Abstract:
    PURPOSE: Many surgical procedures have been described for treating painful osteoarthritis at the carpometacarpal joint of the thumb. This article reports our clinical and radiographic results in performing suspensionplasty using the abductor pollicis longus (APL) tendon without tendon interposition after a complete trapeziectomy for patients with painful osteoarthritis in the carpometacarpal joint of the thumb. METHODS: Eighteen patients (2 men, 16 women), including 21 thumbs with advanced arthritis of the first carpometacarpal joint, who were treated by suspensionplasty using the APL tendon after a complete trapeziectomy were evaluated both clinically and radiographically. Ten thumbs were classified as stage III and 11 were classified as stage IV (Eaton's classification). The average follow-up period was 33.3 months. RESULTS: All patients (18 patients, 21 thumbs) reported pain with daily use before surgery; after surgery 13 of the 21 thumbs had no pain, 5 thumbs had mild pain with strenuous activity, and the remaining 3 thumbs had mild pain with light work. At the final follow-up evaluation the radial and palmar abductions each were 56 degrees +/- 9 degrees and 56 degrees +/- 6 degrees. The grip and key-pinch strengths were 16 +/- 6 kg and 4 +/- 1 kg, respectively. The first metacarpal subsidence at rest was 15% and the additional subsidence when performing a 2-kg key pinch was 6% in the final follow-up radiographic findings. CONCLUSIONS: This study showed that the APL suspensionplasty has a favorable outcome for painful osteoarthritis in the carpometacarpal joint of the thumb and that the APL tendon can be removed as a deforming force without any abduction weakness. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic, Level IV.
