BackgroundTraumatic brachial plexus injuries are severe lesions, and the incidence of these injuries has been increasing in recent years.MethodsThe clinical data of 510 operated patients with brachial plexus injury recruited from 74 hospitals in Guangxi from 2004 to 2016 were retrospectively studied.ResultsOur study included 447 males and 63 females, with an average age of 29.04 years. Traffic accidents were the most common cause of injury (64.71%), especially motorcycle accidents. Closed injuries accounted for 88.24% of cases, and 83.53% of patients had associated injuries, the most common of which were fractures (76.27%). The preoperative predictive value of root injury of MRI and CT was 74.71% and 71.28%, respectively. 44.71% of patients underwent an initial operation within 6 months after the trauma. Regarding the surgery, neurolysis alone, brachial plexus reconstruction, and free functioning gracilis graft accounted for 16.67%, 75.50%, and 4.51%, respectively. A total of 415 patients were followed up with an average time of 47.95 (25–68) months, and anxiety or depression were found among 81.20% of them. Two hundred seventy-six patients suffered from nerve pain, with mild pain present in 67.03% of patients. Additionally, 347 patients were followed up for more than 3 years, 76.81% of patients with C5-C6 injury recovery to useful function, and the procedure of neurolysis alone demonstrated the best efficacy (79.45%).ConclusionsBrachial plexus injury is still a challenging trauma for surgeons, and traffic accidents are the dominant cause. Timely and effective surgery is important for functional limb recovery.
