Three-Corner Midcarpal Arthrodesis and Scaphoidectomy

Abstract

Midcarpal arthrodesis has been a treatment of choice in the last decade for scapholunate advanced collapse and related conditions of the wrist. In this study, we present a new uncomplicated technique in which a 3-corner intercarpal fusion is done with screw fixation from a volar approach. The advantages of this technique include simplified excision of the scaphoid, radial styloidectomy, and straightforward placement of 2 screws from the lunate into the capitate and hamate, respectively, to maintain a readily achievable correction of the dorsal intercalated segment instability. With adequate debridement and compression of the midcarpal joint, fusion is readily achieved.
