Basal joint osteoarthritis of the thumb: comparison of suture button versus abductor pollicis longus suspensionplasty.

Background: Our purpose was to compare the outcomes of patients with severe basilar thumb osteoarthritis treated with trapeziectomy and suspensionplasty using abductor pollicis longus (APL) tendon versus a suture button device.

Methods: A retrospective study was performed for patients undergoing trapeziectomy and suspensionplasty with APL tendon or suture button fixation. Outcome measures included disabilities of the arm, shoulder, and hand (DASH); visual analog score (VAS); grip strength; key pinch; tip pinch; and thumb opposition.
