How to diagnose lumbar spinal stenosis?

Lumbar spinal stenosis is a common disease in orthopedics, which is mainly caused by hyperosteogeny and ligament hypertrophy. At this time, the patient may have symptoms such as low back pain and intermittent claudication. Need to see a doctor in time, after the diagnosis of the disease, can be treated by oral drugs or surgery. Diagnostic methods mainly include imaging and nervous system examination.

In daily life, many people will suffer from lumbar spinal stenosis, which is caused by the compression of nerve roots or cauda equina by lumbar spinal stenosis or intervertebral foramen stenosis. At this time, patients may have a series of symptoms, which seriously affect their health and life. It is necessary to go to orthopedics for diagnosis in time and make clear the condition, so that symptomatic treatment can be effective. So what are the diagnostic methods of lumbar spinal stenosis?

Clinically, lumbar spinal stenosis is mainly caused by hyperosteogeny, spinal trauma and lumbar spondylolisthesis. At this time, patients may have symptoms such as low back pain, intermittent claudication and cauda equina syndrome. It is necessary to go to the hospital for diagnosis, and then use antidepressants and surgery to treat the disease. Diagnostic methods mainly include the following aspects:

1, straight leg elevation test and reinforcement test: the patient lies flat first, then straightens his legs, and the affected limb can feel pain within 60 degrees. In the positive patients, slowly reducing the height of the affected limb, after the radiation pain disappears, passively bending the affected ankle joint, inducing radiation pain again, can be called positive reinforcement test. Most patients will have negative results.

2. Femoral nerve examination: The patient can take prone position, the knee joint can be completely straightened, and the examiner lifts the straightened lower limb to make the hip joint overstretched. When overstretched to a certain extent, pain will appear in the anterior thigh area, and the result is positive.

3. Nervous system: Most patients show skin sensitivity in the early stage, and then slowly appear numbness, tingling, hypoesthesia and other symptoms.

4. Imaging examination: When the patient passes the CT examination, the structure and outline of bone tissue will be clearly displayed, especially the observation of bone stenosis, and calcified tissue can also be clearly seen, but the intervertebral disc and other parts are not fully displayed, but it is also an important means to diagnose the disease.

5.MRI: This method can clearly show the shape of disc herniation or its relationship with surrounding tissues such as nerve roots, and can also judge whether there are other tumors and other space-occupying lesions in the spinal canal.

The above five points are the introduction of the diagnosis method of lumbar spinal stenosis, and the patients have a certain understanding after reading it. Once you find any symptoms in your body, you should see a doctor in time and choose the appropriate method for diagnosis. After the diagnosis of the disease, anti-inflammatory drugs and nutrient nerves can be used for treatment. If drug treatment fails, patients can take surgical treatment.
