Abstract

Proximal row carpectomy (PRC) is an effective treatment option for degenerative or posttraumatic osteoarthritis of the wrist in conditions such as scapholunate advanced collapse, scaphoid nonunion advanced collapse, Kienbock disease, and chronic fracture dislocations of the carpus. PRC involves excision of the scaphoid, lunate, and triquetrum, and relies on the articulation of the remaining capitate from the distal row to articulate with the lunate fossa. PRC offers the potential advantage of greater range of motion, technical ease, and decreased immobilization, and eliminates specific complications found with other motion-preserving procedures such as nonunion, hardware irritation, and impingement. An established relative contraindication for PRC is the presence of advanced capitolunate arthritis. Many authors have offered modifications of the traditional PRC procedure to account for the presence of capitate arthritis. A PRC technique utilizing an osteochondral autograft, from the carpal bank of excised bones, for transfer to the capitate defect is described.
