Abstract
Purpose
To evaluate the functional and radiographic results of a scaphoid excision and four-corner arthrodesis technique using percutaneous headless compression screws.
Methods
A cohort of 33 patients, mean age 51 (range, 20–72) years, was treated for scapholunate advanced collapse (19), scaphoid nonunion advanced collapse (12), midcarpal instability (1), and Preiser disease (1). After scaphoid excision and removal of cartilage and subchondral bone in the midcarpal joint through a limited arthrotomy, capitolunate fixation was achieved with a percutaneous, transmetacarpal Acutrak screw (Acumed LLC, Hillsboro, OR), and triquetrohamate fixation was done with a percutaneous screw. Scaphoid was used as a bone graft. The average follow-up time was 8 months (n = 32; range, 6–64 mo).
