Abstract

Purpose

Partial trapeziectomy addresses trapeziometacarpal (TM) joint arthritis without the risk of destabilizing the scaphotrapezial (ST) joint. However, partial trapeziectomy has been criticized because of concern that ST joint arthritis will develop, requiring additional surgery. We hypothesized that partial trapeziectomy is a durable treatment for TM joint arthritis, even in patients with radiographically abnormal but asymptomatic ST joints.

Methods

We evaluated 13 patients (16 thumbs) who underwent a partial trapeziectomy between 1995 and 2005. Assessment included grip strength, pinch strength, ST joint direct palpation, and ST joint stress testing. We classified standardized radiographs of the ST joint using a simple scoring system. Subjective data included the Disabilities of the Arm, Shoulder, and Hand questionnaire, a pain scale, and a satisfaction survey.
