Digital neurorrhaphy after the age of 60 years.

Fifteen patients over the age of 60 years (average age: 65 years), with 19 digital nerve lacerations, were evaluated more than 1 year after injury. Two-point discrimination, Semmes-Weinstein evaluation, and subjective return of sensibility were examined by a certified hand therapist before and after local anesthetic block of the uninjured digital nerve. Sixty-three percent of the patients regained moving two-point discrimination less than 15 mm; 100 percent regained Semmes-Weinstein values of less than 4.56; and 84 percent of the patients subjectively noted greater than half of their normal sensation. Crossover innervation was a factor in four of 14 repairs. Based on the data, useful sensation can be regained by repairing a digital nerve in the majority of patients older than 60 years of age.
