Patient: description of disease: male, now 35 years old, suffering from low back pain for 5-6 years, previous CT suggests lumbar spine sacralization, the rest of no abnormality, received small needle treatment, the effect is not good, now the symptoms have worsened compared with the previous, mainly lumbar pain, walking distance more feeling of lower limb weakness, used to often do physical work, now rarely participate in physical labor. A few days ago, the examination: lumbar spine sequence is neat, curvature exists, vertebral body edge bone becomes sharp, lumbar 45 vertebrae relative edge can be seen as a band of short T1 and long T2 abnormal signal shadow; each intervertebral disc in the T2WI hypoattenuation and hypoplasia, lumbar 3-4, 4-5, lumbar 5-Sacral 1 discs of varying degrees of compression of the dural sac and the nerve root was arcuate traces of the compression of the lumbar 3-4, 4-5 level of the spinal canal canal narrowing; shown spinal cord cone and the cauda equina morphology, thickness, alignment as usual. The spinal cord cones and cauda equina were shown to be of normal shape, thickness and alignment, with smooth edges, and no abnormal signal shadow was seen in the medulla; no abnormal signal shadow was seen in the paravertebral soft tissues. The effect of small-needle knife treatment is not good How to treat? Sermon: There are three main treatments for lumbar disc herniation: conservative treatment, minimally invasive treatment and open surgery. If the herniation is not serious, generally conservative treatment is the main, you can rest in bed, wear a waist cuff, lumbar paste some blood circulation, pain cream, do not sit for a long time and long time standing, at the same time, lumbar and back muscle exercise, but also oral anti-inflammatory and analgesic drugs such as ibuprofen or fenpropidol. If the effect of conservative treatment is not good, consider minimally invasive surgery or open surgery. There are many kinds of minimally invasive treatments for lumbar disc herniation, including chemical nucleus pulposus fusion, ozone therapy, laser therapy, radiofrequency therapy, percutaneous lumbar disc removal, posterior discectomy, lateral and posterior intervertebral foramina, and so on. At present, minimally invasive intervertebral foraminoscopic surgery is the surgery with wider indications and more accurate effect. Our hospital carried out minimally invasive percutaneous lumbar disc removal and intervertebral foraminoscopic lumbar disc removal to treat lumbar disc herniation at an early stage in China, and the result is better.
