So, a spondylolisthesis is a forward slip of one vertebra (ie, one of the 33 bones of the spinal column) relative to another. Spondylolisthesis usually occurs towards the base of your spine in the lumbar area.This x-ray shows spondylolisthesis in the lumbar spine. Look at where the arrow is pointing: you can see that the vertebra above the arrow has slid out over the vertebra below it. Spondylolisthesis GradesSpondylolisthesis can be described according to its degree of severity.
One commonly used description grades spondylolisthesis, with grade 1 being least advanced, and grade 5 being most advanced. Spondylolisthesis VideoThis is basically another term for spondylolisthesis. Anterolisthesis is a spine condition in which the upper vertebral body, the drum-shaped area in front of each vertebrae, slips forward onto the vertebra below. The amount of slippage is graded on a scale from 1 to 4. Views, where care has been taken to expose for a true lateral view without any rotation, offer the best diagnostic quality.Retrolistheses are found most prominently in the cervical spine and lumbar region but can also be seen in the thoracic area.
Anterolisthesis is a spinal disorder characterized by a dislocation of at least one vertebra relative to another. The disc wall becomes slack and the vertebrae become freer to slide around. The direction of slide is controlled by the Retrolisthesisis the term used to define a degenerative and an acute spine condition in which a single vertebra gets displaced and moves backwards onto the vertebra lying immediately below it. Vertebrae are the bones that make up the spinal column and are separated from each other by cushioning intervertebral discs.In most of the cases, this condition is a result of the rupture or deterioration of these discs.
When the disc is damaged, the vertebra lying above loses support and slips out of its position putting pressure on the vertebra below the disc. It usually occurs in the lumbar region of the spinal column, more prominent at the L3-L4 or L4-L5 levels. Symptoms of Retrolisthesisinclude stiffness in the affected area, chronic back pain that may extend to buttocks and thighs or no pain and numbness.
