Spondylolisthesis

Definition

Forward displacement of a vertebra

Articular processes at the back part of the vertebral bones connect and stabilize the upper and lower bones of themselves. Many factors, congenital, degenerative or isthmic, traumatic damage of the articular processes, can cause a forward displacement of the vertebral bone and compress the spinal nerves.

Symptoms

Pain in buttocks and legs when walking and changing posture

  • 1.Standing and walking cause compression of the nerves and subsequent pain, while standing would relieve the symptoms
  • 2.Numbness of legs
  • 3.Back pain when bending the back forward and lying on the back
  • 4.Pricking pain and numbness when walking
  • 5.Back pain presenting earlier than other people after extended posturing

Cause

Congenital

  • Congenital deformity of articular processes
  • Isthmic

  • Stress fracture of the pars interarticularis
  • Degenerative

  • The muscles and ligaments around the spinal bones have more tension when degenerative changes caused by aging make the interval between the vertebrae narrow. Subsequent instability of the facet may displace the joint even when the joint surfaces are still intact.
