Abstract

It is well known that variations of the innervation in intrinsic hand muscles are common, A detailed anatomic study revealed that Riche -Cannieu anastomosis, a neutral anastomosis between the recurrent branch of the median nerve and the deep branch of the ulnar nerve, was in 77% of cadaveric dissections. Few electrophysiologic study of such anastomosis, however, has been done in a large population.

The second group, 37 MGA -detected limbs of 27 subjects, was also studied in order to evaluate the contribution of MGA to the innervation in intrinsic hand muscles. There was no significant difference in the incidence of anomalous innervation of each muscle in both groups.
