Zusammenfassung: | In the Istanbul Hand Surgery and Microsurgery Centre, between 1991–1996, 28 out of 54 patients who had clean‐cut median nerve laceration at the wrist level were evaluated in a detailed manner regarding the improvement of sensibility following primary repair. Semmes‐Weinstein monofilament and vibration tests form the group of threshold tests, and static and dynamic two‐point discrimination tests and the Moberg pick‐up test form the group of functional tests which were applied to the patients. Follow‐up was from 1 to 5 years. Moreover, subjective findings such as cold intolerance, pain, and paraesthesia were also evaluated. All the results obtained were evaluated in relation to the SO–S4 sensibility improvement criterion which Waylett‐Rendall recommended.1 The following results were obtained: S4 in 35.7% of the patients, S3+ in 28.5%, S3 in 14.2%, S2+ in 7.14%, S2 in 10.7%, and S1 in 3.5%. In our opinion the most important reason for the high rate of success was the fact that we worked with a highly selective group of patients and the fact that there was a high rate of young patients in this group (21.4% of them were under the age of 15). It was observed that there was a significant correlation between age and functional sensibility improvement (P = 0.04). Moreover, when we observed the relation between age and Semmes‐Weinstein monofilament, static two‐point discrimination, and dynamic two‐point discrimination tests, it was seen that age had a significant correlation with each of the parameters (r = 0.61, P = 0.001; r = 0.58, P = 0.002; r = 0.57, P = 0.002). There was a clear decline in the intensity of the paraesthesia in S3+ and S4 group (χ2 = 4.7, P = 0.02) and in these groups the period of Moberg pick‐up test was meaningfully short (P < 0.05). © 1998 Wiley‐Liss, Inc.
