Combined Treatment of Trapeziometacarpal Joint Arthritis and Scapholunate Advanced Collapse Wrist

The combined treatment of trapeziometacarpal joint arthritis and scapholunate advanced collapse (SLAC) wrist presents unique challenges. The consequences of the loss of radial column support caused by scaphoidectomy and trapeziectomy are not well known. The purpose of this study was to evaluate the outcomes of the simultaneous and staged treatment of trapeziometacarpal joint arthritis and SLAC wrist.

A retrospective review of patients who underwent surgery for both trapeziometacarpal joint arthritis and SLAC wrist was performed. The wrist and thumb range of motion; grip and pinch strength; pain; quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) scores; and radiographs were analyzed.

Twenty-four patients who underwent both trapeziectomy and 1 of 3 procedures for SLAC wrist (4-corner fusion [n = 10]), proximal row carpectomy [n = 9], and total wrist arthroplasty [n = 5]) in a single stage (n = 10) or in 2 stages (n = 14) were included. The median age was 63 years. The median follow-up period was 35 months. Twelve (50%) patients underwent complete scaphoidectomy, and 12 (50%) patients underwent partial scaphoidectomy. All 3 procedures resulted in an improvement in pain at rest, pain during activity, and quick Disabilities of the Arm, Shoulder and Hand scores. The final range of motion, grip and pinch strength, and complication rates were consistent with those reported in the literature for isolated procedures.

Trapeziometacarpal joint arthritis and SLAC wrist may be treated either simultaneously or in stages.
