Lumbar spondylolisthesis is a disorder in which the lumbar vertebrae are partially or completely misaligned, and is generally referred to clinically as a slipped vertebra, generally a forward slippage of the superior vertebra. The incidence of lumbar spondylolisthesis is 3-7% in Europe, and there is a lack of accurate statistics in China. It is generally believed that routine X-ray examination of patients with low back pain reveals a tendency for about 5% of adults to suffer from lumbar spondylolisthesis. In fact, there are many types of lumbar spondylolisthesis, including traumatic lumbar spondylolisthesis, degenerative lumbar spondylolisthesis, isthmic spondylolisthesis, and medically induced spondylolisthesis. The most common are degenerative and isthmic spondylolisthesis. Degenerative slippage is mainly due to the degenerative disease of the lumbar spine as the lumbar spine ages, and the stability of the lumbar spine decreases, resulting in a slow forward slip of the vertebral body and lumbar slippage. The isthmic cleft slippage is actually a congenital disease that may exist at birth, but due to the relatively young age and good physical condition, there are no symptoms, which will slowly appear as we grow older and as the degenerative disease of the lumbar spine progresses.
