A preclinical animal model of chronic ligation of the sciatic nerve was used to compare the effectiveness of a slow-release hydrogel carrying methylprednisolone to methylprednisolone injection alone, which simulates the current standard of care for chronic compressive radiculopathy (CR). ⋯ N/A.

Numerous health care resources are utilized to treat low back pain (LBP) resulting from degenerative disc disease (DDD). Most patients with disc degeneration remain asymptomatic, and the degree of disc degeneration does not correlate with pain severity, making diagnosis and effective treatment challenging.

When spinal cord injury (SCI) occurs, injured cells must survive and regenerate to close gaps caused by the injury and to create functional motor units. After peripheral nerve injury, Wallerian degeneration in the distal nerve stump creates a neurotrophic and growth-supportive environment for injured neurons and axons via Schwann cells and secreted cytokines/neurotrophins. In both SCI and peripheral nerve injury, injured motor and sensory neurons must regenerate axons, eventually reaching and reinnervating target tissue (SDC Figure 1, http://links.lww.com/BRS/B116). This process is often unsuccessful after SCI, and the highly complex anatomy of branching axons and nerves in the peripheral nervous system leads to slow recovery of function, even with careful and appropriate techniques.
