The concept of spondylolisthesis was first introduced by Killan in 1854, and in 1930, Jumghamns referred to a slip without a defect in the arch as a pseudospondylolisthesis, and in 1955 Newman called this “spondylolisthesis with an intact arch” in conjunction with its pathological changes. “Degenarative Spondylolisthesis (DS)” and defined it as a type IV lumbar spondylolisthesis. Degenerative lumbar spondylolisthesis is one of the common clinical conditions, which occurs in people over 50 years of age, male: female = 1:4, slipped segments in L4-5 and L5-S1 are common, and most patients have a mild degree of slippage, with Ⅰ° being the most common. The clinical manifestations are mainly lumbar pain and symptoms of lumbar spinal stenosis such as intermittent claudication of neurogenic origin and radicular pain. The pathological mechanism of degenerative lumbar spondylolisthesis is complex and is related to degeneration of the intervertebral discs and small joints, and changes in the structure and flexion of the lumbar spine. Inos believes that the disc plays a relatively important role in the pathogenesis of degenerative lumbar spondylolisthesis, and Hammerberg et al. suggest that when the disc degenerates, the stress is shifted from the nucleus pulposus to the subtalar joint during rotation of the lower lumbar spine, resulting in joint surface reshaping and cartilage surface destruction and bone resorption. that increased torsional and shear forces in slippage both lead to accelerated disc degeneration. In this way, the progression of slippage and accelerated disc degeneration can form a vicious cycle. The majority of degenerative lumbar spondylolisthesis symptoms are caused by lumbar instability or lumbar spinal stenosis. Degenerative lumbar slippage is a loss of mutual restraint between lumbar vertebral segments, causing displacement between vertebral bodies. Translational or rotational position of the vertebrae 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 eventually leads to intractable lower back pain and compression of the cauda equina and lumbosacral nerve roots. However, the concepts of lumbar degenerative slippage and lumbar instability are not exactly equivalent. Instability indicates a loss of vertebral segmental mechanical correspondence under dynamic conditions, whereas slippage indicates an abnormal correspondence between two corresponding vertebral segments. Slippage shows a relatively static condition under many conditions due to joint, capsular ligament, and muscle dynamic constraints, as well as the formation of degenerative bone fragments or bridges. 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. and increased slippage, along with the development of low back pain symptoms. Only 24% of patients without neurologic symptoms had worsening disease and neurologic symptoms, so conservative treatment was effective in most patients without neurologic symptoms. Eighty-three percent of patients with neurologic or cauda equina symptoms had worsening disease and unsatisfactory clinical outcomes, so surgery was recommended for these patients. The symptoms of patients with degenerative lumbar spondylolisthesis are mainly caused by lumbar instability and/or lumbar spinal stenosis, and surgery is mainly for stenosis and instability, and the indications for surgery are: 1. intermittent neurological claudication caused by lumbar spinal stenosis, ineffective conservative treatment for at least 3 months, affecting life, rest and sleep, etc.; 2. progressive aggravation of neurological symptoms; 3. large and urinary dysfunction; 4. lumbar instability After the 1970s, with the widespread application of pedicle screw technology in the field of spinal surgery, a breakthrough in the treatment of degenerative lumbar spondylolisthesis has been achieved, and the basic process of treatment includes internal fixation with the pedicle screw system, decompression of the spinal canal and bone graft fusion.
