The cross-hand finger transfer.

This report is of the first successful case we know of transplantation of a ray (finger and metacarpal) from one hand to another. The transfer was accomplished by a two-stage pedicle technique. The tendons and nerves were left long in the donor finger, and were anastomosed at the second stage when the pedicle was divided. Good sensation was obtained. Active tendon function resulted, with excellent power and range of motion in all of the digits of both hands.
