Degenerative lumbar spondylolisthesis is one of the common clinical diseases, which occurs in people over 50 years old, male: female = 1:4, and slipped segments are common in L4/5 and L5/S1. The clinical manifestations are mainly lumbar pain and symptoms of lumbar spinal stenosis such as intermittent claudication of neurogenic origin and radicular pain. The majority of degenerative lumbar slippage symptoms are caused by lumbar instability or lumbar spinal stenosis. Degenerative lumbar spine slippage is a loss of mutual restraint between lumbar vertebrae, causing displacement between vertebrae. Both translation and rotation of the vertebral body and attachments can lead to changes in the morphology and volume of the spinal canal. This slow-onset change in vertebral body, synovial joint, and spinal canal morphology and volume causes spinal stenosis, which ultimately leads to intractable lower back pain and compression of the cauda equina and lumbosacral nerve roots. Most scholars believe that most degenerative lumbar spondylolisthesis is self-stabilizing and that patients with degenerative lumbar spondylolisthesis should be treated first with systematic non-surgical treatment, with conservative treatment being effective in 70% of patients and only about 30% of patients requiring surgical treatment. Surgery for patients with degenerative lumbar spondylolisthesis is mainly for stenosis and instability, and the indications for surgery are: 1. intermittent neurological claudication caused by lumbar stenosis, ineffective conservative treatment for at least 3 months, affecting life, rest and sleep, etc. 2. 2. Progressive worsening of neurological symptoms. 3.People with large and small bowel dysfunction. 4.Continuous or recurrent lumbosacral pain caused by lumbar instability, ineffective by systematic regular conservative treatment, affecting life and work, etc.
