Sensory recovery after median nerve grafting.
Fourteen patients were evaluated prospectively after median nerve grafts. Twelve male and two female patients with a mean age of 41 years were included. Mean time since surgery was 4 years. Detailed sensory evaluations were completed. Statistical evaluation analyzed relationships between object identification, sensory tests, and graft length. According to the S-0 to S-4 grading system, 11 patients were considered to be S-3+ or greater. Recovery of moving two-point discrimination of 2 to 3 mm. was achieved by 50% of the patients. Strong correlations were found between object identification and static two-point discrimination, moving two-point discrimination, and graft length. Cutaneous pressure threshold and vibration threshold correlated weakly with object identification.
