    Abstract:
    BACKGROUND: Restoration of upper arm function presents the main priority in nerve repair of brachial plexus traction injuries. The results are predominantly influenced by the level and extent of injury, and the type of surgical procedure. The purpose of this study is to evaluate influence of these factors on final outcome. METHODS: Study included 91 surgically treated patients, including 71 patients with avulsions of one or more spinal nerve roots and 20 with peripheral traction injuries. We performed 120 nerve transfers, 25 nerve graftings and 29 neurolyses on different nerve elements depending on the type of nerve damage. Analysis of motor recovery for elbow flexion and arm abduction, isolated or in combination, was done. FINDINGS: Recovery of elbow flexion was obtained in 75% nerve transfers, and in 68,7% nerve graftings in peripheral traction injuries. Recovery of arm abduction was obtained in 78,5% nerve transfers, and in 44,4% nerve graftings in peripheral traction injuries. Neurolysis was successful in all cases. Generally, the quality of recovery was better for the musculocutaneous nerve. Useful global upper arm function was obtained in 49,3% of patients with avulsion of spinal nerve roots, and in 55% of patients with peripheral traction injuries. INTERPRETATION: Regarding upper arm function the prognosis of surgically treated patients with traction injuries to the brachial plexus is generally similar in cases with central or peripheral level of injury. However, nerve transfers of collateral branches seem to be superior to nerve grafting and may be another possibility for repair in cases with extensive nerve gaps.
