ABSTRACT
Peripheral nerve injury is a relatively common sequela of trauma. Nerve regeneration and target re-innervation are complex processes, and remain clinical challenges. For a long period of time, the placement of an autologous nerve graft is the gold standard. However, autologous nerve grafts are limited in supply due to its potentially associated with donor site morbidities. Therefore, researchers keep seeking the ideal alternatives for neural repair. The clinical application of artificial nerve regeneration conduit has made incremental advancement. Specifically, compound conduits are gaining more and more attention, which are reported to have comparable effect to autologous nerve graft. The purpose of this paper is to review the progress of construction and application of compound nerve conduits in peripheral nerve repair.
