Abstract
A series of 44 patients with complete section of the ulnar nerve was reviewed on average 2 years after secondary repair. The procedures applied were fascicular grafting in 33 cases, epineural suture in 7, and fascicular suture in 4. Useful ulnar motor function was restored in 22 cases of fascicular grafting, in all 4 of fascicular suture and in 3 of epineural suture. Sensibility recovered in 23 patients operated on by fascicular grafts and in 10 of 11 treated by epineural or fascicular suture. Cases with unsatisfactory results had other associated severe lesions, i.e., median nerve section, vascular damage or tendon injuries. Early repair of clean-cut nerve sections by fascicular or epineural suture gives a good chance for recovery. Grafting should be performed within 3 months and no later than 1 year after the injury.
