Abstract

This study aimed to investigate whether ultrasonographic inspection of the repair site of median nerve lacerations may provide useful evidence about the functional outcome in the affected hand. Forty-three patients with complete transection of the median nerve at the distal forearm were examined at a median of 40.9 months after operation by detailed ultrasonographic imaging and clinical assessment of the affected hand by the Michigan Hand Questionnaire and Rosén-Lundborg Protocol to investigate the quality of nerve healing. The continuity of individual nerve fascicles was assessed and the cross-sectional area of the enlarged nerve at the repair site was measured and compared with the contralateral median nerve at the same level. An enlargement ratio for the repair site of each nerve was calculated and compared with the numeric results obtained from the two clinical tests. A statistically significant reverse correlation was observed between nerve enlargement and the functional results of the repaired nerve. Level of evidence: IV
