Nerve Biology
A 32-year-old man sustains a complete laceration of his median nerve at the wrist during a glass injury. He undergoes primary nerve repair 6 hours after injury. At the 3-month follow-up, the surgeon percusses along the forearm and elicits tingling radiating to the fingers at the mid-forearm level. The patient asks about the expected timeline for motor and sensory recovery. Regarding peripheral nerve regeneration biology:
