Spondylolisthesis is a condition in which one or several vertebrae (vertebrae) shift forward from the bone underneath or above. Generally, this spinal cord shift occurs in the lumbar spine region of the L4-L5 vertebra (Lumbal 4-5 lumbar) and or L3-L4 (Lumbal 3-4 vertebrae). But in another vertebra, this vertebral shift can occur. The shift of the vertebral segment can occur at two levels or even three levels simultaneously. Not possible, the shift of the vertebral segment occurs in the neck region, which is generally preceded by abnormalities in the facet joints of arthritis.

Each level of the spine consists of a series of bones (vertebrae) separated by soft pads (discus intervertebral). The spine sequence is stabilized in its position by the facet joint which also serves to resist the movement of the spine in excess. This allows the spine to bend forward (flexion) and back (extension) but it is not possible to perform multiple rotational movements (rotating / spinning).
