Biopolymers in the Treatment of Peripheral Nerve Injuries

Today, one of the most common hospital and clinical visits of nervous system problems is related to the injuries after accidents that disrupt the lives of injured.According to statistics, half a million surgeries are registered annually in the United States due to the peripheral nerve tissue damage, and the cost of these surgeries is estimated at about 1.5 billiondollars.Also,more than300,000 peripheral nerve injuriesare reported annuallyin Europe and over 5 million worldwide.Trauma is the most common cause of peripheral nervous damage, and neurological injuries often cause muscle-traumatic neuronal damage.In this article, new methods of treatment of peripheral nerve tissue are reviewed.In this paper, new methods and biopolymers used in the treatment of peripheral nerve tissue injuries are reviewed.Generally,peripheral nerve tissue treatment classified into grafts (autograft, allograft, and xenograft) and nerve conduits (decellularized nerve conduits and manufactured nerve conduits). Synthetic neurotransmitters are also divided into three general categories of biodegradation (polyesters, proteins and polysaccharides), synthetic (polyesters, polyurethanes and polyols) and hybrid neurotransmitters, whicheach of these methods is discussed in detail.
