|
|
Purpose: The purpose of this study was to evaluate surgical outcomes of thumb carpometacarpal osteoarthritis treated either by volar ligament reconstruction or trapeziectomy with suspensionplasty.
Materials and Methods: From July 2004 to January 2011, we treated 43 patients with thumb carpometacarpal joint arthritis by volar ligament reconstruction in stages I and II, and by trapeziectomy with suspensionplasty in stages III and IV. Out of the 43, we evaluated 19 patients (9 treated by volar ligament reconstruction, 10 treated by trapeziectomy with suspensionplasty) at an average of 36.8 months (range: 8 to 65 months) after surgery. Outcome measures included pain visual analogue scale (VAS), ranges of motion, and grip and pinch strengths.
Results: The mean VAS was 1.2 in the volar ligament reconstruction group and 2.0 in the trapeziectomy with suspensionplasty group at final follow-up. The ligament reconstruction group had significantly better thumb radial abduction and opposition ranges of motion, and key grip strength. No further radiographic arthritic changes were noted in the ligament reconstruction group at a mean follow-up of 39 months.
Conclusion: The authors obtained satisfactory pain control in patients with thumb carpometacarpal osteoarthritis by volar ligament reconstruction for stages I-II and trapeziectomy with suspensionplasty for stages III-IV.
