[Improved outcome of nerve injuries in the upper extremity].
Nerve injuries in the upper extremity can result in severe disability. In the past three decades, progress in microsurgical techniques and instruments have resulted in improved outcomes for nerve injuries. If the prognosis is reasonably good, nerve repair is usually preferred over tendon or flap transfer procedures. However, lesions of peripheral stem nerves such as high radial nerve palsy may still yield unsatisfactory results, despite technically well-executed nerve repair. Prognosis further depends on the age of the patient; the regenerative process is delayed in older patients. Further criteria for the indication for tendon transfers are the personal and professional profiles of individual patients. Tendon or flap transfers to restore sensation can be performed at any time post trauma when it becomes clear that long-term rehabilitation is required. These procedures abbreviate the interval during which hand function is severely impaired, so that patients have alternatives to persistent nerve palsy with the need of permanent external splints, and long and costly rehabilitation can be shortened. Sophisticated techniques allow minimal donor site morbidity and leave options open in case function of the reconstructed nerve returns. The present article gives an overview of the most common procedures to restore hand function and sensation in the most important digits and provides help for decision making.
