Clinical Studies on Combined Lesion of the Median and Ulnar Nerve at Wrist

Abstract

Sixteen cases of combined lesion of the median and ulnar nerve were treated from 1967 to 1977. The follow-up results were classified by Higher's and Zachary's criteria. The following results were obtained:
1) Of 4 cases after neurolysis, all recovered near-normal sensory and motor function both in median and ulnar nerve.
2) In 9 cases after nerve suture, 77.7% showed a recovery of over-M₃, 55.5% over-⁺₂ and an useful recovery was obtained in 55.5% in median nerve, 33.3% were in category of over-M⁺₂, 66.0% in over-S⁺₂ and an useful recovery was regained in only 33.3% in ulnar nerve.
