Lumbar spondylolisthesis: the lumbar vertebrae (mostly lumbar 4 and 5) slip forward (or backward) due to the loss of the linkage of the vertebral arch, resulting in compression of the cauda equina or nerve roots in the spinal canal, variation of the lumbar spine bearing force, and a disease with lumbar pain or lower limb paralysis and pain as the main manifestation. Beijing 306 Hospital Orthopedics Ji Yong etiology: the cause of lumbar spine slippage can be congenital (present at birth) or acquired, occurring in childhood or later. It is mainly caused by various excessive mechanical stresses, and triggers include lifting heavy objects, weightlifting, soccer, sports training, trauma, wear and tear.
