Aim: Treatment options for traumatic brachial plexus injuries include nerve grafting, or neurotization. The type of lesion and the reconstructive procedures affect functional results and postoperative pain relief.
Material and methods: A total number of twenty five patients suffering from post-traumatic brachial plexus injury were included in the study. The patients underwent exploration and primary repair of the affected plexus, based on case by case policy.
Results: Spinal accessory nerve transfer to suprascapular nerve procedure regained 78.95% of functional muscle power, 10.50% of non functional muscle power and only 10.5 % of non innervated muscle. The Oberlin procedure regained 83.33% with elbow flexion muscle power, 16.67% with non functional muscle power. Intercostal nerve transfer to musculocutaneous nerve regained 62.5% with functional muscle power, 25% with non functional muscle power and only 12.5 % with non innervated muscle. The shoulder, elbow and wrist extension functions were significantly improved early post-operatively. In addition, the post-operative improvement of shoulder, elbow and wrist extension functions had significant negative correlations with the pre-operative elapsed time, and accompanied by a significant positive correlation with post-operative follow up period.
Conclusion: Early intervention for traumatic brachial plexus palsy is recommended to get good results with pain relief.
