Background: In injuries of the lower brachial plexus, finger flexion can be restored by nerve or tendon transfer. However, there is no technique that can guarantee good recovery of finger and thumb extension.
Objective: To determine the spinal nerve origins of the muscular branches of the radial nerve and identify potential intraplexus donor nerves for neurotization of the posterior interosseous nerve in patients with lower brachial plexus injuries.
Methods: An intraoperative electrophysiological study was carried out during 16 contralateral C7 nerve transfers. The CMAP (compound muscle action potential) of each muscle innervated by the radial nerve was recorded while the C5-T1 nerves were individually stimulated.
This is a video of a twenty-five-year-old man who suffered complete brachial plexus avulsion, three years after reinnervation of the suprascapular nerve, axillary nerve, musculocutaneous nerve and the branches to the long head of the triceps brachii, demonstrating shoulder and elbow function.
This is a video of a 25-year-old man who suffered complete brachial plexus avulsion, three years after reinnervation of the medial portion of the antebrachial part of the radial nerve at the level of the latissimus dorsi insertion with a full-length phrenic nerve, demonstrating wrist and digit extension function.
