Functional restoration of elbow flexion in nonobstetric brachial plexus injuries: A meta-analysis of nerve transfers versus grafts.

The ulnar or pectoral nerve transfer to musculocutaneous is associated with statistically significant superior rates of elbow flexion recovery as compared to graft. No differences were identified in the pooled analysis or the subgroups of other donors used in nerve transfers. Future randomized studies or prospective cohorts are needed to validate our results.
