Intercarpal fusion for the treatment of scaphoid nonunion.

Salvage of the ununited scaphoid may not always be feasible or advisable, hence the availability of a number of alternative techniques which prioritize restoration of pain relief and range of motion. The role of intercarpal fusion reflects the importance of midcarpal stabilization when the scaphoid is resected. While scaphocapitate and scaphocapitolunate fusions have been described, these techniques provide less pain relief than midcarpal fusion with scaphoid excision, and are associated with an increased risk of radioscaphoid arthritis. In this article, the author will address the rationale for, technique of, and outcome after midcarpal arthrodesis and scaphoid excision.
