OBJECTIVES To determine the characteristics of neuropathic pain and the somatic nerve lesions most frequently encountered in the context of chronic pelvic and perineal pain. MATERIAL AND METHODS Review of the literature devoted to pelvic and perineal neuralgia. RESULTS The diagnosis of pelvic and perineal pain related to a somatic nerve lesion is(More)
Ischemia of the motoneurons in the anterior horn is a well known pathological entity. Their clinical signs and symptoms are similar to those of amyotrophic lateral sclerosis. Evidence by selective angiography of angiomas of the spinal cord or compression or deviation of Adamkiewicz artery may be suggestive of an initial vascular lesion. Various data(More)
Perineal pain is the basis of presentation to different specialities. This pain is still rather unknown and leads the different teams to inappropriate treatments which may fail. For more than twenty years, we have seen these patients in a multidisciplinary consultation. Our anatomical works have provided a detailed knowledge of the nervous supply of the(More)
Neuropathic perineal pains are generally linked to suffering of the pudendal nerve. But some patients present pains described as a type of burning sensation located more laterally on the anal margin and on areas including the scrotum or the labiae majorae, the caudal and medial parts of the buttock and the upper part of the thigh. These pains extend beyond(More)
OBJECTIVE To determine the mechanisms involved in the regulation of pelvic and perineal pain. MATERIAL AND METHODS Description of the anatomical pathways mediating nociceptive transmission and the physiological mechanisms of pain control. RESULTS The pelvis and perineum do not have the same innervation. The pelvis is innervated by the sympathetic(More)
The pudendal is the king of the perineum. Most often originating in the S3 root, it is responsible for the teguments of the perineum (glans penis, clitoris, scrotum, and the labia majora, the skin of the central fibrous perineal body, anus), but also the erector muscles and the striated sphincters. The social nerve, it controls erection and the voluntary(More)
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(More)
PURPOSE Rectal examination is difficult to carry out by students because of their lack of knowledge and fear. It is therefore necessary to search for methods in order to facilitate its practice. This work mainly focuses on the palpation of the posterior lateral area of the rectum. METHODS This work bases itself on the study of the average length of(More)
In addition to the well-established syndrome of pudendal compression, and given the rich nerve trunk innervation of the perineum, pain originating in other nerve trunks can occur and must be remembered. Nerves originating high in the thoracolumbar area (ilioinguinal nerve, iliohypogastric nerve, genitor femoral nerve) can be the seat of traumatic lesions(More)
Confusion between radicular and nerve trunk syndrome is not rare. With sciatic pain, any nerve trunk pain or an atypical nerve course should suggest nerve trunk pain of the sciatic nerve in the buttocks. The usual reflex with sciatic pain is vertebral-radicular conflict. The absence of spinal symptoms and the beginning of pain in the buttocks and not in the(More)
