    Abstract:
    OBJECTIVE: To analyze retrospectively the outcomes of primary as well as secondary functional reconstructions in 49 patients with traumatic brachial plexus lesions from a single service. Guidelines for treatment might be extracted from this analysis. METHODS: Among 152 cases of traumatic lesion of the brachial plexus presented to our clinic, 58 underwent primary brachial plexus reconstructive surgery. On exploration, all patients showed stretching and scarring of plexus elements; root avulsions were found in 28 patients (48%). Outcome evaluation was carried out in 49 of these patients with a follow-up period of 1 year or longer (mean follow-up, 27.9 mo; range, 12-72 mo). A total of 43 secondary reconstructive procedures to improve functionality of the involved arm were performed at a later stage in 25 of 58 patients. Outcomes of the secondary functional restorative procedures were evaluated (mean follow-up, 11.5 mo; range, 3-60 mo in 43 procedures). RESULTS: Patients with neurolysis as a stand-alone procedure (11 patients) showed an outcome grade of 4 or 5. The average outcome of the 19 patients with C5, C6, and C7 grafting was Grade 3, the same as in patients with nerve transfers to the upper plexus elements (C5-C6 root avulsions, 13 patients). Patients with multiple root avulsions (five cases) showed an overall poor outcome (Grades 0-2). Secondary functional restorative surgery was performed in 43% of the patients and helped improve individual outcomes, providing a favorable effect on the general functionality of the arm. Among the restorative operations performed, the Steindler procedure, wrist extension restoration, claw hand correction, and free functional muscle flap transfer to the arm and forearm were the most rewarding. CONCLUSION: A combination of primary brachial plexus reconstruction and carefully evaluated, selected, and planned function-restorative secondary procedures might offer favorable outcomes in patients with partial or total brachial plexus lesions.
