OBJECTIVE: Treating brachial plexus injuries is a major challenge, especially lesions that are presented late, with more than 12 months of evolution. We retrospectively analyzed patients who underwent one of the possibilities for attempting to restore the function of upper limbs affected under such conditions: microsurgical transfer of the gracilis muscle for elbow flexion.
METHODS: Eight patients were included, divided into two groups: one in which the procedure consisted of neurorrhaphy of the muscle flap with sural nerve grafting and anastomosis more distally; and the other, in which the neurorrhaphy was performed directly on the spinal accessory nerve, with anastomosis in thoracoacromial vessels.
RESULTS: We found a significant difference between the groups. A greater number of satisfactory results (75% M4) were found among patients who underwent direct neurorrhaphy, whereas the procedure using grafts for neurorrhaphy was less successful (25% M4).
CONCLUSION: Patients who underwent microsurgical functional transfer of the gracilis muscle in which vascular anastomoses were performed in thoracoacromial vessels presented better functional outcomes than shown by those whose anastomoses were in the brachial artery with subsequent use of a nerve graft.
