Spondylolisthesis

Definition

Spondylolisthesis is a condition in which a bone (vertebra) in the lower part of the spine slips forward and onto a bone below it.

Symptoms

Spondylolisthesis may vary from mild to severe. A person with spondylolisthesis may have no symptoms.

The condition can produce increased lordosis (swayback), but in later stages may result in kyphosis (roundback) as the upper spine falls off the lower spine.

Symptoms may include:

• Lower back pain
• Muscle tightness (tight hamstring muscle)
• Pain in the thighs and buttocks
• Stiffness
• Tenderness in the area of the slipped disc

Nerve damage (leg weakness or changes in sensation) may result from pressure on nerve roots and may cause pain radiating down the legs.
