obturator muscle sign

The examination of the intramyocardial muscle sign is an auxiliary diagnosis method for examining the obturator muscles by CT, X-ray and other techniques to diagnose the corresponding symptoms. Obturator nerve compression syndrome refers to a group of symptoms and signs mainly caused by the pain of the obturator nerve passing through the obturator membrane. , nerve release, satisfactory results. Obturator nerve compression syndrome is characterized by muscle pain and weakness in the area dominated by obturator nerves. There may be muscle atrophy in the late stage, skin sensation in the corresponding area is reduced, muscle strength of the adductor muscle is decreased, abduction is limited, and the obturator is closed. There is deep tenderness and radiation to the inside of the lower extremities, and the symptoms are aggravated when the abdominal pressure is increased. As the disease progresses, the above symptoms gradually increase, and there may be intermittent claudication. Basic Information Specialist classification: growth and development check classification: CT Applicable gender: whether men and women apply fasting: not fasting Tips: Inappropriate crowds: Adolescents, women should try not to have radiation tests during pregnancy. Normal value The obturator is a large hole between the ischial bone and the pubic bone, and the edge is sharp, and the obturator film is attached thereto. The obturator tube is a fiber-bone tube with a length of about 2 to 3 cm. The obturator tube has two internal and external ports from the outside to the lower, and the obturator artery, vein, and nerve pass through. The inner mouth of the obturator tube is filled with fat. Organization, can only accommodate fingertips when normal. Clinical significance Abnormal results The obturator nerve is a mixed nerve with sensation and movement. It consists of the anterior branch of the first lumbar vertebrae to the fourth lumbar vertebrae. After crossing the obturator, it is divided into two branches, the anterior and posterior branches. The muscles of the adductor, the longissimus and the superficial skin; the posterior branch dominates the adductor muscle. The obturator nerve still has a hip branch at the obturator. Whether it is a bone lesion or a soft tissue lesion around the obturator, it can constitute a compression of the obturator nerve. Lesions around the obturator, such as local tissue congestion, edema, calcification, hyperplasia, fracture displacement, and callus formation, may cause the obturator nerve to be compressed. Because obturator nerves have joints that support the ipsilateral hip joint, some patients may present with symptoms such as hip pain, acidosis, and weakness. Electromyography examination suggests obturator nerve injury, and obturator closure facilitates diagnostic treatment. Obturator nerve compression syndrome should be differentiated from high-level lumbar disc herniation, femoral nerve compression and obturator stenosis caused by gynecological and surgical diseases. Older women who need to be examined, who are thin, may have a similar history of seizures, multiple pregnancy and childbirth, and patients with habitual constipation and other medical history should be examined. Precautions Taboo before the examination: the patient should be nervous, and the family should avoid entering the examination room to reduce unnecessary radiation. Requirements for inspection: Actively cooperate with the doctor to allow the doctor to accurately check the location of the disease. X-ray irradiation by ordinary physical examination, when the CT scan is performed, the adult does not exceed one time each year. The anti-cancer examination for middle-aged and elderly people should also be controlled within one time each year. Adolescents, women are special people during pregnancy, try not to do X-ray examination. If X-ray examination is required for treatment diagnosis, lead protection products should be worn. Inspection process 1. X-ray inspection: (1) Abdominal and pelvic X-ray plain film: It has the following image features: 1 general intestinal obstruction image; 2 small intestine and gas-liquid plane with proximal obstruction are fixed above the pelvic pubic bone, and the sign remains unchanged after changing the position; 3 closed There is gas in the hole or an inflated bowel, and the blind end points to the closed hole, which is a typical X-ray appearance of the closed hole. (2) sac sac angiography: adapted to the intermittent appearance of intestinal obstruction symptoms, the sac of the obturator sac can be observed during the interstitial sac. (3) CT scan: CT scan is helpful for the diagnosis of this disease. There is a low-density dense shadow between the obturator muscle and the pubis muscle when the pelvic scan is not incarcerated. The mass of the tumor shows a distinct gas density and intestinal tube. Expansion; after incarceration, the intestinal shadow can be seen from the inside of the closed hole into the closed hole, and the intestinal tube above the intestinal shadow in the closed hole has signs of intestinal obstruction, and the closed hole can be diagnosed. 2. B-ultrasound: abnormal intestinal tube reflected waves can be seen in the tender part. Not suitable for the crowd no.
