title: Peripheral nerve surgery--today and looking ahead.
abstract: The trend in peripheral nerve surgery is toward earlier definitive treatment of the lesion, based on the optimal use of preoperative and intraoperative electrodiagnostic techniques. Newer diagnostic tools include computed tomography (CT) and thermography. Knowledge is still being gained about the technology and limitations of the autogenous nerve grafts that are being used to overcome nerve gaps. The technique of nerve anastomosis is undergoing rapid improvement, and better methods have been developed for identifying motor and sensory fascicles at the time of operation. Research activity into the problem of nerve damage produced at the time of trimming nerve stumps promises to change to the technology of nerve repair in the near future. For benign nerve sheath tumors (schwannoma, neurofibroma), the trend is away from nerve excision and in the direction of tumor enucleation. Histologic methods for diagnosing malignant nerve tumors have been improved, making it possible to embark on radical excision with less hesitation. The pain syndromes (causalgia, phantom limb pain, and stump pain) that may follow nerve injury continue to present a problem in management, but steady progress is being made toward a rational program of management. A more distant prospect is for pharmacologic and electrophysiologic methods to accelerate axonal regeneration.
