Seven patients required removal of peripheral nerve trunks due to resecion of bone and soft tissue tumors. After resection of the tumor with the diseased portion of the nerve trunk, five patients underwent immediate repair of the nerve (interposition nerve graft, the length of 8-13cm). Two patients each had malignent shwannoma and malignant fibrous histiocytoma, and one patient had a neurilemoma. Ages of the patients ranged from thirty to sixty years. Five were female. The proximal thigh and proximal lower leg was involved in two patients each and the groin in one patient each. The distal common peroneal nerve was used as the graft for repair of the proximal tibial nerve in two patients who had resection of the sciatic nerve, the distal superficial peroneal nerve was used for proximal deep peroneal nerve repair in one patient in whom the common peroneal neve was resected and the sural nerve was used for common peroneal nerve repair in one patient with resection of the common peroneal nerve. The median follow-up was 45 monrhs. Four patients (80%) achieved a good recovery of the repaired nerve function and one patient (25%) had minimal recovery.
