Abstract

The purpose of this study was to compare the outcome of scaphoid excision with capitolunate and triquetrohamate arthrodesis (bicolumnar arthrodesis) to radioscapholunate arthrodesis in patients with scapholunate advanced collapse (SLAC) II wrist arthritis. Twelve patients with symptomatic SLAC II arthritis were recruited and randomized to receive either bicolumnar arthrodesis or radioscapholunate arthrodesis. The primary outcome was wrist function as assessed by the patient rated wrist evaluation. Secondary outcomes included range of motion, grip strength and the Mayo wrist score. A linear mixed-effects model was used to evaluate the effects of bicolumnar arthrodesis and radioscapholunate arthrodesis in treating SLAC II arthritis. Patients receiving bicolumnar arthrodesis had more improvement in their wrist function compared with patients receiving radioscapholunate arthrodesis. A high rate of re-operation was observed in patients receiving radioscapholunate arthrodesis. In SLAC II arthritis, the expected benefit of preserving the midcarpal joint was not observed. Scapholunate ligament disruption makes radioscapholunate arthrodesis a technically challenging operation.Level of evidence: I
