ABSTRACT
Nerve injuries may result in sensory and motor deficits when not treated appropriately. Especially the surgical management of nerve defects still represents a challenge for the surgeon. In these cases the grafting of autologous nerves represents the only reasonable approach. Due to the side effects associated with this method (sacrifice of donor nerves, neuroma formation in the harvesting area, limited availability of donor nerves, etc.), numerous alternatives were proposed in order to avoid the transplantation of autologous tissue. This review provides a general view on the state of the art of how to supply gaping injuries in the peripheral nerve. Furthermore new approaches emphasizing tubulization techniques for the reconstruction of lost nerve tissue are described with a special focus on various materials with their advantages and disadvantages.
