To evaluate the functional outcome after complete median nerve transaction and repair, and sensory reeducation.

We studied 40 patients, aged 20 to 32 years, with median nerve neurotmesis at the wrist. Primary epineural microsurgical repair using 8-0 single strand sutures was done in all patients, and a hand and wrist cast was applied for 4 weeks. After cast removal all patients went through physical therapy for 1 month to restore motion and reduce stiffness of the injured hand. After reinnervation was completed, the patients were randomly allocated into 2 equal groups: Group A patients were instructed to a sensory re-education program; Group B patients had no further treatment. Clinical evaluation was done at 18 months postoperatively including the localization test (locognosia), the static and the moving 2 point discrimination tests, the Moberg’s pick-up test (stereognosia), and the hand grip and the opposition strength tests.

All patients were included in the postoperative evaluation. Hand grip and opposition strength, static and moving two point discrimination were not statistically significant between the two groups (p= 0.622, p= 0.112 and p= 0.340, respectively). The localization test was statistically significant in group A (p= 0.007), and a trend to statistical significance was observed regarding the Moberg’s pick up test in group A (90% statistical significance, p= 0.063).

Sensory reeducation is essential for patients with median nerve neurotmesis and repair, as it significantly re-educates localization and stereognosia in the shortest time following peripheral nerve injury and repair
