The carpal scaphoid cannot be partially or totally excised without paying a functional penalty, usually in the form of carpal instability. In selected conditions, however, a partial scaphoidectomy may be preferred over other less reliable alternatives. These include excision of a small fragment of a fractured proximal pole when there is no injury to the scapholunate ligaments; excision of the distal fragment of a nonunited, arthritic distal-third scaphoid fracture; resection-arthroplasty of isolated STT osteoarthritis; and distal scaphoid excision to improve midcarpal function after a radioscapholunate fusion. In this article, both the pathomechanics and clinical results of such techniques are discussed.
