Purposeful Misalignment of Severed Nerve Stumps in a Standardized Transection Model Reveals Persistent Functional Deficit With Aberrant Neurofilament Distribution

Abstract

Functional recovery following primary nerve repair of a transected nerve is often poor even with advanced microsurgical techniques. Recently, we developed a novel sciatic nerve transection method where end-to-end apposition of the nerve endings with minimal gap was performed with fibrin glue. We demonstrated that transected nerve repair with gluing results in optimal functional recovery with improved axonal neurofilament distribution profile compared to the end-to-end micro-suture repair. However, the impact of axonal misdirection and misalignment of nerve fascicles remains largely unknown in nerve-injury recovery. We addressed this issue using a novel nerve repair model with gluing.
