Summary One, if not the only effective way of treating pain due to preganglionic avulsion of the brachial plexus is the Dorsal Root Entry Zone (DREZ) lesion procedure. In 1985 the author began to use ultrasound as a lesion-maker for operations in the DREZ. Since then, 127 (3 patients were operated on twice) DREZ-Operations have been carried out on 124 patients suffering from chronic pain due to brachial plexus avulsion. Different technical lesioning modalities were employed: ultrasonic discontinuous DREZ lesions in 20 cases and a new modality: ultrasonic DREZ-sulcomyelotomy in 107 cases. |
