[Endoscopically assisted nerve decompression of nerve nerve compression syndromes at the upper extremity].

Besides carpal tunnel and cubital tunnel syndrome, other nerve compression or constriction syndromes exist at the upper extremity. Using the technique of endoscopically assisted decompression such rare nerve compression syndromes of the upper extremity can be treated. The technique of endoscopical decompression is presented in six patients with rare compression or hour-glass-like constriction syndromes at the upper extremity. According to the classification of Roles and Maudsley in 5 of 6 cases excellent results were recorded. All but one patient considered the results excellent. The poorest responder developed a CRPS II and refused postoperative physiotherapy. Endoscopically assisted decompression in rare compression syndrome of the upper extremity is highly appreciated by patients and provides excellent functional results.
