The purpose of this paper is to review our experience with the treatment of nerve injuries in the upper extremity. Since 1950 We have had an opportunity to treat 325 cases of this type. Tables 1, 2, and 3 summarize the nerves which were injured and the level of the injury. In those cases in which more than one nerve was injured, as in multiple lacerations of the digits or combined median and ulnar nerve lesions in the Wrist, the injury is counted as a single case. This group of patients was treated between January, 1950, and January, 1957. The follow-up period varies from one to seven years. Age and Sex One hundred ninety-five of these patients Were men and eighty-one women. There is no difference in the results of nerve repair attributed to the patient's sex. Forty-nine of the patients were 14 years of age or younger (Table 4).
