Repair of ventral root avulsions of the brachial plexus: a review

Traumatic root avulsions of the brachial plexus constitute a devastating lesion resulting in loss of function of the upper limb and carry a large emotional and socioeconomic impact. In this literature survey, the different factors involved in root avulsion are discussed in combination with various surgical techniques for repair of experimental ventral root avulsion. Until now repair of root avulsions did not generate unequivocal proof of recovery of limb function, particularly of the hand. More experimental studies are needed to assess the efficacy of several repair techniques, the optimal timing for surgery, and the complications associated with spinal cord manipulation.
