Abstract
Background:
This study represents the clinical results, especially range of motion (ROM) improvement, of arthroscopic partial trapeziectomy with suture-button suspensionplasty for symptomatic grade II and III thumb carpometacarpal arthritis with a minimum 1-year follow-up.
Methods:
Thirty-two patients (mean: 67.5 years) with grade II and III thumb carpometacarpal arthritis treated with arthroscopic partial trapeziectomy with suture-button suspensionplasty were retrospectively followed up for at least 1 year. The physical assessments included ROM, pain visual analogue scale (VAS), strength, and the Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire. The physical variables were retrospectively compared before surgery and at the final follow-up.
Results:
Preoperative radial abduction and palmar abduction (45.4 ± 16.4° and 54.3 ± 13.9°, respectively) were significantly increased at the final follow-up (59.7 ± 16.9° and 65.5 ± 14.2°, respectively). Preoperative VAS score, pinch strength, and DASH score (70.5 ± 14.0, 57.2 ± 24.8% and 36.8 ± 14.8, respectively) were also significantly improved at the final follow-up (7.9 ± 9.1, 91.0 ± 39.6%, and 11.7 ± 10.5, respectively). Complications involved 1 case of irritation of the superficial branch of the radial nerve and 1 case of dystonia. Two suture-buttons were removed due to patient discomfort.
Conclusions:
A significant increase in ROM and pain relief was obtained after suture-button suspensionplasty with arthroscopic partial trapeziectomy.
