ScienceDaily (Apr. 22, 2012) — Engineers at the University of Sheffield have developed a method of assisting nerves damaged by traumatic accidents to repair naturally, which could improve the chances of restoring sensation and movement in injured limbs.

In a collaborative study with Laser Zentrum Hannover (Germany) published April 23, 2012 in the journal Biofabrication, the team describes a new method for making medical devices called nerve guidance conduits or NGCs.

The method is based on laser direct writing, which enables the fabrication of complex structures from computer files via the use of CAD/CAM (computer aided design/manufacturing), and has allowed the research team to manufacture NGCs with designs that are far more advanced than previously possible.

Currently patients with severe traumatic nerve damage suffer a devastating loss of sensation and/or movement in the affected limb. The traditional course of action, where possible, is to surgically suture or graft the nerve endings together. However, reconstructive surgery often does not result in complete recovery.
