Which statement accurately describes the prognosis of neurotmesis?

• A. Excellent prognosis with therapy
• B. Poor prognosis due to complete nerve division
• C. Good prognosis with early surgical repair
• D. Prognosis depends on patient age

Answer: (B)

Neurotmesis is the most severe peripheral nerve injury, involving a complete transection of the nerve and disruption of its surrounding connective tissue. Because the axons are fully severed and the guiding endoneurial pathways are lost, spontaneous reinnervation across the gap does not occur. Without surgical repair to realign and reconnect the nerve ends, recovery is unlikely. Even when surgical repair is performed, outcomes are variable and often limited, since regenerating axons must grow long distances and reinnervate muscles that may have atrophied or reorganized, and misdirection of fibers can limit functional return. Early repair can improve the chance of recovery compared with delayed intervention, but it does not guarantee a good outcome. Age and other factors can influence regeneration, yet the defining issue remains the complete division of the nerve.
