title: Reanimation of elbow extension with medial pectoral nerve transfer in partial injuries to the brachial plexus.
abstract: OBJECTIVE
  Recent 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.
  
  
  METHODS
  This 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.
  
  
  RESULTS
  The 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.
  
  
  CONCLUSIONS
  The medial pectoral nerve is a reliable donor for elbow extension recovery in patients who have sustained C5-7 nerve root injuries.
