A long-term study of ring finger transfer in the reconstruction of transmetacarpal amputations.
Restoration of adequate function in patients with metacarpal hands is a major challenge. In 1984, we presented a technique in which the contralateral uninjured ring finger was transferred by microvascular techniques to restore the dual hand functions of pinch and palmar grips. This was performed in combination with thumb reconstruction when necessary. The original 5 patients described in 1984, as well as 2 later cases, were reviewed for a long-term follow-up study (average, 19 y; range, 8-25 y). The average age of the patients at follow-up evaluation was 44 years (range, 13-73 y). Range of motion, grip span, sensibility, and grip strengths were measured. The Disabilities of the Arm, Shoulder, and Hand outcome measure was used to evaluate disability. The data show persistent good function with improving sensibility over the years. The ring finger transfer in reconstruction of transmetacarpal amputation has proven to be a good technique with an overall satisfactory outcome, especially in its ability to restore some capacity for palmar grip, a function that has hitherto been unattainable by other means.
