After the treatment of patients with lumbar disc herniation, doctors always ask patients to wear lumbar girth. First of all, we should know that the main purpose of wearing lumbar girth for patients with lumbar disc herniation is braking, which is to limit the movement of the lumbar spine such as flexion, especially to assist the back muscles to limit some unnecessary forward flexion movements to ensure that the injured lumbar disc can be fully rested locally. Especially in patients with acute lumbar disc herniation, there can be varying degrees of muscle spasm due to the acute local inflammatory response and stimulation, and wearing a lumbar girth reduces the activity of the waist and can play a role in strengthening protection. The reasonable use of lumbar girth can also reduce the strain on the muscles of the lumbar back, reduce the burden on the ligaments around the lumbar vertebrae in a relaxed posture, and relieve and improve the pressure in the intervertebral space to a certain extent. What should I pay attention to when wearing a lumbar girth? When wearing a lumbar disc herniation, the following points should be noted: 1. The specifications of the lumbar girth should be compatible with the length and circumference of one’s waist, and its upper edge should reach the lower edge of the rib and the lower edge to the hip crack. The back side of the waist circumference should not be too convex, to flat or slightly convex forward is good. Do not use too narrow waist circumference, so as not to overly convex lumbar vertebrae, and do not use too short waist circumference, so as not to abdomen too tight. Generally, you can try it on for half an hour first, so as not to produce discomfort. 2, wear the waist circumference can grasp the time according to the condition, in the waist symptoms are heavy, should often wear with, do not take off at any time, light patients, can wear the waist circumference when going out, especially to stand for a long time or a posture when sitting, and then take off during sleep and rest. After the symptoms gradually subside and the signs gradually become negative, the waist circumference should be removed and the normal activities of the waist should be gradually resumed. 3, after wearing the waist circumference should pay attention to the waist activities, because the waist circumference only restricts the activities of flexion and other aspects, but can not reduce the gravity, so wear the waist circumference should still pay attention to avoid excessive activities of the waist, generally to complete daily life, work as degree. For patients after surgery, serious lumbar fractures, dislocations, etc., lumbar activities should be carried out according to medical advice, and the lifting of the lumbar girth should also be agreed by the doctor. 4, during the use of lumbar girth, should also gradually increase the lumbar back muscle exercise under the guidance of a doctor, in order to prevent and reduce the atrophy of the lumbar muscle. Can lumbar girth be worn for a long time? The normal human body supports the strength of the lumbar spine mainly from its own waist and abdominal muscles, rather than the brace given by the outside world. Patients with lumbar disc herniation or other lumbar diseases in the early stage of the disease, the pain is heavy, need to be bedridden for a long time, emotional, walking difficulties, when wearing a lumbar brace can not only support the patient’s waist, but also “support” the patient’s emotions, to reduce their mental stress. However, if this leads to the idea of dependence, it will be very problematic, because long-term use of the waist brace can reduce muscle and joint activity, secondary to muscle wasting atrophy, lumbar spine joints of different degrees of ankylosis, resulting in reduced mobility. The result is that the patient cannot leave the lumbar girth or the pain will increase, or the atrophied muscles will be weaker after lifting the girth and cannot adapt to activities without the protection of the girth, and may cause new injuries and strains. Therefore, wearing a waist girth is generally for 4-6 weeks and should not exceed 3 months at the longest.
