We often see such examples in the clinic, and there is a considerable part of the orthopedic surgeon habitually take the film as the main evidence of diagnosis, as long as the film suggests that there is a lumbar disc herniation imaging manifestations, i.e., to give the patient under the diagnosis of lumbar disc herniation. Clinically, most of the causes of low back pain are caused by lumbar disc herniation, but there are also a small number of other causes, such as the previously mentioned “sacroiliac arthropathy” and “lumbar triple transverse syndrome”, “gluteal epiphyseal neuritis “Lumbar spinal stenosis, hypertrophy of the ligamentum flavum, calcification of the posterior longitudinal ligament, chronic diseases of the soft tissues of the low back, and so on. Chronic disorders”, etc. There are also some internal diseases that can cause low back pain. These diseases are not difficult and can be easily diagnosed by a doctor with some clinical experience as long as he or she is careful. The key to accurate diagnosis is not the film, is to ask the patient in detail the nature of the pain and regularity, in addition, the most important thing is the doctor’s physical examination, only the symptoms in line with the need to provide a basis for the film, based solely on the lumbar vertebrae X, CT or MRI film for the lumbar disc herniation diagnosis, it is too arbitrary, often over-diagnosis, over-treatment, misdiagnosis and incorrect treatment of the phenomenon, which is daily life, we will often see. This is something we often see in our daily life. To clearly diagnose lumbar disc herniation, we must first clarify several concepts: 1, lumbar disc herniation and lumbar disc herniation are not exactly the same concept: lumbar disc herniation, as the name suggests, is originally in the intervertebral space of a part of the intervertebral disc tissue protruding from its original position, from the CT or MRI slides, you can see the protruding disc tissue protruded into the spinal canal or out of the spinal canal, but it is not necessarily produce the corresponding symptoms. produce corresponding symptoms. Lumbar disc herniation, on the other hand, occurs when the herniated disc tissue irritates or (and) compresses the nerve roots of the corresponding segment, resulting in nerve root compression and irritation, i.e., lumbar and leg pain. Therefore, there is a big difference between the absence of symptoms called lumbar disc herniation and the presence of symptoms called lumbar disc herniation. 2, the nature and pattern of lumbar disc herniation pain: (1) typical lumbar disc herniation pain in the back and legs, must be the lightest in the morning, and in the case of prolonged walking or prolonged sitting, the back and lower extremity pain will be aggravated. (2) Low back pain occurs in the early stages of lumbar disc herniation, when there can be no leg pain, but when leg pain is present, the low back pain usually decreases or disappears. (3) In the case of lumbar 3-4 disc herniation, the location of lower limb pain is in the anterior and posterior thighs without involving the calves; in the case of lumbar 4-5 disc herniation, the location of lower limb pain is in the lateral thighs and calves; in the case of lumbar 5-sacral 1 disc herniation, the location of lower limb pain is in the posterior thighs and calves. 3, lumbar disc herniation specific body examination: Verification of lumbar disc herniation specific examination there are many, here only list two commonly used, effective. (1) Positive straight leg raising test: the patient lies on the bed in supine position, the healthy side of the lower limb is straightened and lifted first, and then the affected side of the lower limb is straightened and lifted after being put down, if there is lumbar disc herniation, the height of the lower limb on the affected side is obviously lower than that of the healthy side, and numbness and string pain will appear according to the route of the nerve root. (2) Positive cervical flexion test: the patient lies supine on the bed, the doctor lifts the patient’s head upward with his hand, if there is lumbar disc herniation, there will be numbness and string pain on the affected side according to the route of the nerve root. 4, the lower limbs have numbness, indicating aggravation of the disease: as the saying goes, “pain light hemp heavy wood difficult to heal”, lumbar disc herniation just sick, generally will be the pain in the lower limbs as the main symptom, with the prolongation of the course of the disease, the pain will be alleviated, but there will be a gradual occurrence of the affected lower limbs of the numbness, which at this time shows that the nerve root compression longer, the disease aggravated. 5, most of the lumbar disc herniation conservative treatment is possible: according to relevant statistics, 88-92% of patients with lumbar disc herniation can be treated conservatively to make the symptoms disappear, and maintain a normal life and work status, in daily life we often see patients with lumbar disc herniation, only occasionally clinical symptoms, after treatment, the symptoms disappeared, most of the time there is no symptom, this state! This state can appear in most disc patients, which shows that lumbar disc herniation does not necessarily require surgery. In short: the film shows that there is a lumbar disc herniation, also have back pain and leg pain, is not necessarily suffering from lumbar disc herniation, must go to the hospital, looking for specialists, careful examination, in order to do the correct diagnosis, reasonable treatment.
