Suture-Button Suspensionplasty for Thumb Carpometacarpal Arthritis: A Minimum 2-Year Follow-Up

PurposeTo retrospectively review the results at a minimum of 2 years of suture-button plasty with partial or full trapeziectomy and suture-button suspensionplasty.MethodsWe evaluated 21 patients who received suture-button suspensionplasty at least 2 years after surgery. We measured postoperative pinch strength, grip strength, range of motion, and metacarpal height. All patients also completed the Quick Disabilities of the Arm, Shoulder, and Hand questionnaire.ResultsAt an average follow-up of 2.8 ± 0.7 years, the mean Quick Disabilities of the Arm, Shoulder, and Hand score was 10 ± 9. Pinch and grip strengths were 86% and 89% of the contralateral limb, respectively. Average first trapezial height was 74% of the contralateral trapezial height. There were no major complications.ConclusionsThe favorable results of the suture-button suspensionplasty procedure confirm its usefulness in treating thumb carpometacarpal arthritis with minimal risk of complications, ineffective fixation, or loss of function. Subjective and objective outcomes measures are similar to previously described techniques. The benefit of this technique results from the implanted nature of the suspensionplasty elements that require no time to heal, so rehabilitation is begun as early as 10 days postoperatively.Type of study/level of evidenceTherapeutic IV.
