Using Highet's criterion and Zachary's criterion for usefulness, postoperative therapeutic results were examined for 36 cases of median and ulnar nerve injuries (43 nerves) at the forearms. Operative procedures comprised epineural suture under microscopy (24 cases), sural nerve garfting (1 case) and epineural suture under macroscopy (11 cases). Results:
In terms of microscopy or otherwise, definitery better results were obtained in the microscopic cases. From the viewpoint of primary or secondary suture, for incised wounds secondary suture can be expected to obtain as good a result as primary suture when performed within 6 months, and from the viewpoint of age and nervous recovery of the patient, very good results were obtained in all of the cases less than 10 years, while cases more than 40 years remarkably showed poor results.
