Fifty-one Herbert-screw fixation procedures were performed for interphalangeal fusion in the hand. The preoperative diagnoses included rheumatoid arthritis, degenerative arthritis, posttraumatic arthritis, and chronic mallet finger. All patients were observed until there was clinical and radiographic evidence of union. Solid osseous union occurred in all patients. Herbert screw fixation for interphalangeal arthrodesis was a simple, effective technique permitting early mobilization; complications were minimal.
