REPAIR OF LARGE PERIPHERAL NERVE GAPS

Experimental Approaches on Tissue Engineering Repair of Peripheral Nerve Gaps

Peripheral nerve research is highly dynamic and a current major focus is the development of cell based supportive therapies as well as bioengineered nerve conduits to overcome the challenges in reconstructing long peripheral nerve defects. Whenever primary nerve repair cannot be performed without regeneration impairing tension at the suture sites, autologous nerve grafting or nerve tubulization...

Overcoming short gaps in peripheral nerve repair: conduits and human acellular nerve allograft.

Nerve conduits and acellular nerve allograft offer efficient and convenient tools for overcoming unexpected gaps during nerve repair. Both techniques offer guidance for migrating Schwann cells and axonal regeneration though utilizing very different scaffolds. The substantially greater amount of animal and clinical data published on nerve conduits is marked by wide discrepancies in results that ...

XWH - 12 - 1 - 0513 TITLE : Large Extremity Peripheral Nerve Repair

Peripheral nerve injury and repair.

Peripheral nerve injuries are common, and there is no easily available formula for successful treatment. Incomplete injuries are most frequent. Seddon classified nerve injuries into three categories: neurapraxia, axonotmesis, and neurotmesis. After complete axonal transection, the neuron undergoes a number of degenerative processes, followed by attempts at regeneration. A distal growth cone see...

Timing and technique of peripheral nerve repair.

Surgery of the peripheral nerves is briefly reviewed with special emphasis on the timing and the techniques of nerve repair. The sooner a severed nerve can be repaired, the better the quality of the recovery. While delays of a few months after injury appear to have no serious effect on the out come of nerve sutures, the chances of successful recovery decline after six months. It is not common f...
