The Demography of Traumatic Brachial Plexus Avulsion Injuries.

Abstract

Background and objectiveBrachial plexus injuries more commonly affect the younger generation who constitute the productive workforce. The patients who sustain avulsion injuries of the brachial plexus are more often involved in high-velocity accidents. The avulsion injuries are surgically managed by nerve transfers. This study aimed to evaluate the demography of brachial plexus avulsion injuries.Materials and methodsThis retrospective study was conducted in January 2013 and included 21 patients treated from January 2007 to December 2011.ResultsOf the 21 patients, 20 were male and the most commonly affected patients were in the age group of 21-30 years. The mean age of the affected patients was 27.24 years. Six of the patients had pan palsy (C5-8 and T1), nine had C5-7 injury, and six had C5-6 injury. Twenty patients underwent spinal accessory to suprascapular nerve transfer, nine patients underwent ulnar nerve fascicle to nerve to biceps branch transfer, and one patient underwent intercostal nerve to musculocutaneous nerve transfer. Of note, 40% of the patients regained more than M3 power for abduction and external rotation of the shoulder, and 30% of the patients regained more than M3 power for elbow function.ConclusionsRoad traffic accidents are the most common cause of brachial plexus injuries. Nerve transfers for shoulder and elbow function play a significant role in improving the function of the upper extremity.
