What are the histological features of nerve root compression?
Under the microscope, nerve root compression can be identified by several key features. These include axonal degeneration, loss of myelin sheath, and fibrosis around the nerve root. Additionally, there may be evidence of Wallerian degeneration, where the distal part of the injured nerve undergoes degeneration. The presence of Schwann cells attempting to remyelinate the damaged axons can also be observed.
