Degenerative lumbar scoliosis belongs to adult scoliosis, which is a scoliosis deformity caused by degenerative changes in the spine in skeletally mature patients with a Cobb angle greater than 10 and usually less than 40. The clinical manifestations of degenerative lumbar scoliosis are recurrent episodes of low back pain that progresses more rapidly, is not easily relieved by medication, and is aggravated by back pain with activity. The symptoms are long-lasting, recurrent, and worsen from year to year. Patients may have intermittent claudication, and their nerve compression symptoms occur mainly on the concave side (narrowing of the nerve pathway) or on the convex side (stretching and displacement of the nerve). Patients often have low back pain that is mild in the morning, but gradually feel worse in the afternoon or evening as they move around during the day, making it difficult to support their bodies to the point of changing position to relieve the pain. Mild scoliosis and milder symptoms can be relieved by conservative treatment, including bed rest, pain medication, physical therapy and functional exercise. For significant low back pain caused by severe degenerative lumbar scoliosis, conservative treatment is often ineffective and surgery is recommended. The surgical approach is focused on eliminating pain and is divided into long- and short-segment scoliosis orthopedic internal fixation to restore the balance of the affected spine and to rebuild stability.
