Objective: We sought to combine Medical Research Council (MRC) grading with the Disability of the Arm, Shoulder and Hand (DASH) questionnaires and Numerical Rating Scale (NRS) for pain to evaluate the functional outcome of patients who suffered complete brachial plexus avulsion before and after nerve transfers. Methods: The author carried out a retrospective review of 37 patients with global avulsion of the brachial plexus from 2010 to 2012. All of them underwent nerve transfers in Hua Shan Hospital in Shanghai. They were followed up for over 3 years for physical examination and responding to the questionnaires of DASH, NRS, as well as the satisfaction with the surgery. Results: The mean time to surgery was less than 6 months and the mean follow-up period was 4.59 years. The effective motor recovery rate was 54%, 86%, 46%, and 43%, respectively, in supraspinatus, biceps, triceps, and finger flexor. Patients who underwent nerve transfers scored consistently better on the DASH score and NRS score than those before surgery. There was also a significant correlation between the change in NRS scores and patient satisfaction. Conclusion: This study validated the effect of nerve transfers for global brachial plexus avulsions from objective MRC grading combining with patients’ self-assessments. Neurolysis after neurotizations correlated positively with functional outcomes.
