Locking Plate Arthrodesis Compares Favorably with LRTI for Thumb Trapeziometacarpal Arthrosis: Early Outcomes from a Longitudinal Cohort Study.

ABSTRACT:

Background

Trapeziometacarpal arthrodesis (TMA) has been complicated by nonunion and hardware failure.

Questions/purposes

We hypothesized that modification of the TMA technique with a locking cage plate construct would afford reliable bony union while producing greater hand function than trapeziectomy with ligament reconstruction and tendon interposition (LRTI) at early follow-up.

Methods

We enrolled 36 consecutive patients with trapeziometacapal osteoarthritis (14 TMA patients (15 thumbs), 22 LRTI patients (22 thumbs)). The study was powered to detect a minimal clinically important difference on the QuickDASH questionnaire between groups. Secondary outcomes included Michigan Hand Questionnaire (MHQ), VAS-pain, and EQ-5D-3L scores. Patients were examined to evaluate t
