The Outcome of Neurotization of Brachial Plexus Injury in a Tertiary Centre: A Nine-Year Review

Introduction: In neurotization or nerve transfer, a healthy but less valuable nerve is transferred to re innervate a more important motor territory that has lost its innervation through irreparable damage to its nerve. Methodology: In this study, the outcomes of surgery were analyzed in relation to the muscle strength, range of motion of the upper limb, and functional outcome. The results were analyzed in 19 patients who were operated on between 2008 and 2016 with adequate follow-up. Result: Of the 19 patients (15 complete brachial plexus injuries and four incomplete brachial plexus injuries), 13 patients (68%) recovered partial function after the neurotization surgery. Shoulder abduction and elbow flexion were achieved in 11 patients (58%). Six of the 10 patients (32%) in complete pre ganglionic brachial plexus injury had recovered partial function. Whereas five of the six patients (83%) in complete post-ganglionic had recovered partial function. In incomplete upper trunk brachial plexus injury, three of the four patients (75%) recovered some function after the neurotization surgery. Conclusion: Nerve transfer is an effective treatment option to restore the function of the affected upper limb. Neurotization without intervening nerve graft shows better recovery. Earlier surgical intervention at a younger age can yield better outcomes.
