As the name implies, “degenerative lumbar scoliosis” is an abnormal lateral curvature of the lumbar spine. Patients present with low back pain, shortened walking distance, lower extremity pain, numbness, and inability to sit or stand for long periods of time. The incidence of scoliosis in adults is 4.4% between the ages of 50 and 60 and 8.6% between the ages of 60 and 70, with a corresponding increase in the incidence in patients over the age of 70. Progression of scoliosis can occur in approximately 80% of patients with degenerative lumbar scoliosis. Based on our bulk case observations scoliosis progresses 2° to 6° per year. The disease occurs in middle-aged and older adults and is a new occurrence of lumbar scoliosis in adulthood. Degenerative lumbar scoliosis often has an insidious onset and gradually worsens, and patients are often found to have lumbar scoliosis when they present to the hospital with clinical symptoms. Patients with clinical symptoms of lumbar scoliosis often have compression of the lumbar nerves emanating from the spinal cord in the lumbar spinal canal, lateral saphenous fossa, and nerve root canal, causing lower extremity symptoms such as soreness and shortened walking distance in the lower extremities of patients, as well as pain in the lower back of patients due to degeneration of the lumbar spine and compression of the nerves in the lumbar spinal canal. Patients with degenerative lumbar scoliosis need to undergo X-ray, CT, MRI and other examinations to observe the site and degree of spinal stenosis caused by lumbar scoliosis; combined with the patient’s clinical manifestations, conservative treatment or surgical treatment is adopted. Patients with mild clinical symptoms and small scoliosis can be temporarily treated conservatively to observe the progress of scoliosis and changes in clinical symptoms. For patients with greater scoliosis and more severe clinical symptoms, surgical treatment is required. The surgical treatment can be done by selective decompression short segment fixation fusion and selective decompression long segment fixation fusion. The latest view is that the key to surgical treatment lies in the process of surgical decompression. The patient’s scoliosis stenosis is carefully evaluated before surgery, the stenosis segment is accurately decompressed, and the patient’s symptoms improve significantly after surgery by means of short-segment fixed fusion of the lumbar spine, while short-segment fixed fusion significantly reduces surgical trauma.
