Resection replantation of the upper limb for aggressive malignant tumors.

Abstract

Stage IIB malignant tumors of the upper limb have been traditionally treated by amputation or disarticulation. There have been isolated reports on the technique of segmental resection of the tumor-bearing segment complete with the skin, and replanting the distal arm or forearm with or without neurovascular repair. The present paper describes four cases in which a wide resection margin was achieved in all by resecting the affected cylinder of the limb. Functional reconstruction was performed by appropriate tendon transfer. The main vessels and nerves were dealt with according to the findings revealed by preoperative investigations. If they had to be sacrificed, end-to-end suture was performed, but if the main nerves could be spared, it greatly enhanced the functional outcome. Local and systemic recurrences occurred in one case, and systemic recurrence occurred in another case. The other two cases remained disease-free at more than 4 years' follow-up. This operation is as radical as amputation, while the esthetic and functional results are equivalent to those of resection-arthrodesis.
