Age-related spinal stenosis is the most common cause of lumbar and leg pain. According to the etiological analysis, the human spinal cone gradually degenerates and ages in adulthood, which is manifested in the lumbar spine by the gradual thickening of the intervertebral discs to the lateral and posterior expansion of the ligaments between the vertebral bodies, the hypertrophy of the articular eminence, the thickening or calcification of the ligaments, and other factors that reduce the volume of the spinal canal cavity, resulting in spinal stenosis. Spinal stenosis differs from spinal stenosis in that the former is only a morphological change that can occur without pain, while the latter has morphological changes accompanied by symptoms such as low back pain, leg pain or weakness of the lower limbs due to nerve root compression. There are many traditional treatment methods for lumbar spinal stenosis. Such as acupuncture, physical therapy, massage, surgery, etc. After years of study and clinical practice, the Department of Anesthesia and Pain of our hospital has completed the theoretical summary and treatment characteristics of the treatment of spinal stenosis. They have adopted the spinal interventional treatment technique, which uses imaging localization technology as a guide to inject drugs accurately into the lesion, thereby rapidly relieving the patient of severe radicular pain caused by nerve root compression. This method is accepted by more and more patients because of its non-invasive, non-blood transfusion, short operation time, few side effects and reliable efficacy.
