[Clinical, neurophysiologic and therapeutic remarks from anatomic data on the pudendal nerve in some cases of perineal pain]

Abstract

Clinical observations in patients suffering from positional perineal pain have led us to performing an anatomical study of the pudendal nerve in order to demonstrate compression of this nerve trunk by elements likely to compress it in the sitting position. Thus we observed that the falciform process of the sacrotuberous ligament may act in this way. Besides helping us to understand the clinical symptoms, this anatomical study allowed choosing the technique we found most appropriate for the anatomical conditions observed out of the various neurophysiological examinations described in the literature. Lastly, we describe the surgical technique that allows releasing the trunk of the pudendal nerve under an operating microscope.
