Age-related lumbar spinal stenosis is the most common cause of low back pain, and was first described in detail by Dr. Erbiest, a Danish physician, in 1949. According to etiological analysis, the human spine gradually degenerates or ages in adulthood, which is manifested in the lumbar spine by posterior/lateral bulging of the intervertebral disc, thickening of the posterior ligaments between the vertebrae, hypertrophy of the synovial joints, thickening or calcification of the ligamentum flavum, 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 and can occur without painful symptoms. The latter has morphologic changes along with symptoms such as back pain, leg pain, or weakness of the lower extremities due to nerve root compression. The disorder is now being studied and treated clinically as a separate disease. There are many traditional treatments for lumbar spinal stenosis, such as acupuncture, physical therapy, massage, various painkillers, and pain spot injections, which can significantly relieve the symptoms of some patients. Orthopedic surgery is an effective treatment for the disorder. Given the physical reasons of many elderly patients and the limitations of surgery, there are still some elderly patients with severe lumbar pain who cannot relieve their symptoms through non-surgical treatment. Minimally invasive spinal interventional technology is a cutting-edge technology developed in clinical medicine in recent years. This technology uses imaging localization technology to quickly relieve patients of severe radicular neuralgia caused by nerve root compression after inserting a puncture needle or drug injection catheter through a 1-2mm wound under local anesthesia and injecting ozone and drugs into the lesion site precisely, respectively. Interventional techniques are ideal for the treatment of senile spinal stenosis pain because they do not require incision, no blood transfusion, short operation time, little side effects, reliable efficacy, and are more easily accepted by patients than open surgery.
