Efforts Towards Enhancing the Peripheral Nerve Regeneration: Current Update

Peripheral nerve injuries remain a significant clinical challenge due to suboptimal functional recovery, even with surgical intervention. This article critically reviews current adjunctive strategies aimed at enhancing outcomes after peripheral nerve repair. The modalities discussed include electrical stimulation, erythropoietin, tacrolimus, methylcobalamin, gene therapy and stem cell-based interventions. For each modality, we examine proposed mechanisms of action, quality of evidence and translational relevance. Special attention is given to differentiating findings from animal models and their applicability to clinical practice. Rather than highlighting speculative biological mechanisms, this review focusses on evaluating the clinical utility and limitations of each approach to guide evidence-based therapeutic decisions. Level of Evidence: Level V (Therapeutic)
