Peripheral Nerve Injuries in the Hand:Secondary Repairment of Divided Peripheral Nerves

概要

Although the repairments of the peripheral nerve have been developed in cases recently, there are some controversies over the timing of the secondary repairment. We have experienced 14 cases (18 nerves) of secondary repairment of divided peripheral nerve injuries. There are 5 nerves of the ulnar nerve, 3 of the median nerve, 2 of the radial nerve and 8 of the digital nerve. All cases were sutured with epineural suture microscopically, and these postoperative results were evaluated by using Heighet's criterion and the static two-point discrimination method. No significant differences were observed between the timing before and after 3 month from the initial injuries. However, neuromas and relative big scars at the nerve stumps were observed in the cases which repair was performed after 3 months. We suggest that the large gap should be avoided, so the timing of secondary repairment is better within 3 months after injuries.
