title: Peripheral nerve injuries in children.
abstract: Recovery after peripheral nerve injuries in children is more complete than in adults and is inversely related to the age of the patient. The prognosis for the return of sensation following laceration of the median, ulnar, or digital nerve depends upon recovery of two point discrimination (in millimeters approximately equal to the child's age) at the time of nerve repair. The better results in children probably reflect the greater adaptability of the immature central nervous system to the nerve injury. Operative exploration of an open wound when there is a potential for nerve injury in an uncooperative child is the only sure way of determining the status of the nerves. Primary repair of cleanly divided nerves in tidy wounds is advocated if it can be done competently. Secondary repair is indicated for avulsion injuries, gunshot wounds, crush injuries, and human or animal bites. Delicate, atraumatic technique and accurate repair of the divided nerve are stressed. The more exacting technique of funicular repair may yield better results. Interfascicular cable grafting is a new and useful alternative to extensive mobilization in closing nerve gaps. Nonoperative treatment of nerve injuries associated with closed fractures is advocated unless there are no signs of nerve regeneration in two to three months. Obstetrical brachial plexus injuries of the upper plexus carry a better prognosis than lower plexus or total plexus injury. Early range of motion exercises to prevent contractures are stressed. Maximal recovery takes place within two years. The acute nerve compression syndrome should be considered an emergency and may require surgical decompression if it is severe and if rapid return of function does not occur following reduction of the fracture.
