Surgical reconstructions for adult brachial plexus injuries. Part I: Treatments for combined C5 and C6 injuries, with or without C7 injuries.

Brachial plexus injuries will cause a significantly decreased quality of life. Patients with upper arm type brachial plexus injuries, which means C5 and C6 roots injury, will lose their shoulder elevation/abduction/external rotation, and elbow flexion function. Additional elbow, wrist, and hand extension function deficit will occur in patients with C7 root injury. With the advances of reconstructive procedures, the upper arm brachial plexus injuries can be successfully restored through nerve repair, nerve grafting, nerve transfer, muscle / tendon transfer and free functioning muscle transfer. In this review article, we summarized the various reconstructive procedures to restore the function of shoulder and elbow. Nowadays, the upper arm type BPI can be treat with satisfied outcomes (80-90% successful rate).
