Excision of the triquetrum and distal pole of the scaphoid frees up the mid-carpal joint, improving radial deviation and the flexion-extension arc of motion of the wrist. This offers an alternative to complete wrist arthrodesis for posttraumatic arthrosis of the radiocarpal joint. An anterior interosseous neurectomy is believed to decrease some pain transmission from the wrist but because the fusion is done dorsal, cutting this volar structure is not routinely done. Fascial interposition is not needed because the capitolunate should be preserved in posttraumatic radiocarpal arthrosis. Sectioning of the dorsal intercarpal ligament would provide no benefit. If the triquetrum is excised, then an ulnar shortening osteotomy is unnecessary.
