    ObjectRecent advancements in operative treatment of the brachial plexus authorized more extensive repairs and, currently, elbow extension can be included in the rank of desirable functions to be restored. This study aims to describe the author's experience in using the medial pectoral nerve for reinnervation of the triceps brachii in patients sustaining C5-7 palsies of the brachial plexus.MethodsThis is a retrospective study of the outcomes regarding recovery of elbow extension in 12 patients who underwent transfer of the medial pectoral nerve to the radial nerve or to the branch of the long head of the triceps.ResultsThe radial nerve was targeted in 3 patients, and the branch to the long head of the triceps was targeted in 9. Grafts were used in 6 patients. Outcomes assessed as Medical Research Council Grades M4 and M3 for elbow extension were noted in 7 (58%) and 5 (42%) patients, respectively.ConclusionsThe medial pectoral nerve is a reliable donor for elbow extension recovery in patients who have sustained C5-7 nerve root injuries.
