To evaluate the efficacy of the technique of dual Mini TightRope suspensionplasty for treatment of trapeziometacarpal joint arthritis.
We conducted a retrospective study investigating the use of a dual Mini TightRope suspensionplasty technique from 2010 to 2013 at a single institution. We identified 11 patients (12 thumbs). Grip and pinch strength, thumb range of motion, and complications were reviewed. The trapezial space ratio was measured from the preoperative, postoperative, and follow-up radiographs. All patients completed the Disabilities of Arm, Shoulder, and Hand survey, Patient-Rated Wrist Evaluation, and the Michigan Hand Outcome Questionnaire at the latest follow-up.
Dual Mini TightRope suspensionplasty resulted in reduced pain levels, increased grip and pinch strength, and preserved range of motion. Radiographs demonstrated maintenance of trapezial space height at an average of 17 months (range, 10-26 mo). There were no cases of impingement or fracture of the first and second metacarpal bases.
Therapeutic IV.
Dual Mini TightRope suspensionplasty for the management of trapeziometacarpal joint arthritis yielded satisfactory results with improvement in strength and function.
