What causes spondylolisthesis?

Bad back: Spondylolisthesis is a forward sliding of a vertebra, typically in the low back. It is caused by a number of things including chronic poor posture and obesity. Congenital defects, osteopenia and osteoporosis can also make you more susceptible.

Several things: One common causes are stress fracture of the pars, the part of bone between the facet joints. Another is arthritis of the facet joints leading to the slip. An acute fracture can cause a slip. Abnormal bones in the posterior back (dysplasia). Abnormal bone is an uncommon cause (pathologic). Aggressive surgery can weaken the spine enough to lead to slip (spondylolisthesis).

Spondylolisthesis: Spondylolisthesis is the slippage of one vertebrae over another. Causes can be degenerative arthritis, trauma/fracture, congenital, or stress fracture of the pars intraarticularis which is often caused by sports involving hyperextension of the back.
