The first replantation of an arm in the Western world was performed by Malt in 1962 and Komatsu and Tamai reported the successful replantation of a completely amputed thumb in 1965.

Without accurate repair of bones, nerves and tendons in addition to vascular anastomosis, however, it is impossible to gain functional success when replanting a digit or limbs.

Although there have been many reports of microvascular surgical technique for successful replantation involving digit, hand and upper extremities. little has been mentioned about 속 functional results in these patients.

The authours have examined electrodiagnostic study and analyzed the functional results of replanted patients (21 cases), transfered from OS department for physical therapy and occupational therapy.

The results were as follows;

1) The average age was 29.7 years and the male to female sex ratio was 10:1.

2) The level of amputation in 21 rehabilitation was as follows: Arm, 1 case; forearm, 3 cases; wrist, 2 cases; palm, 2 cases; thigh, 1 case; all fingers, 2 cases in each except index 3 cases.

3) Type of injuries was incomplete injury in 19 cases, and complete injury in 8 cases.

4) Patient assessment of replanted limbs was relatively satisfied with replanted limbs, but objective assessment of limbs was moderately satisfied.

5) Range of motion in replanted limbs was very poor results.

6) Motor nerve conduction study was gradually regenerated and, so only 2 cases were not conducted after 2 years and sensory nerve conduction study only 5 cases were conducted with decreased amplitude and delayed latendy after 2 years.

7) Electrophysiologic findings were gradually increased motor unit and amplitude with polyphasic motor unit and only a few museles were no motor unit.
