We treat more than 600 patients with spondylolisthesis each year.

Spondylolisthesis is the actual slipping forward of the vertebral body (the term "listhesis" means "to slip forward") (Fig. 3). It occurs when the pars interarticularis separates and allows the vertebral body to move forward out of position causing pinched nerves and pain. Spondylolisthesis usually occurs between the fourth and fifth lumber vertebra or at the last lumbar vertebra and the sacrum. This is where your spine curves into its most pronounced "S" shape and where the stress is heaviest.

We believe that traumatic spondylolisthesis with laminar fracture may probably be caused by an extension and axial load combination type injury, however, without laminar fracture hyperflexion type injury is the most likely cause, asymmetric lesions includes rotational component. But its occurrence mechanism in each particular case will be challenging to be exactly defined as both type of injury patterns with their subtypes, may cause to similar radiological findings. Biomechanical studies may help to understand the physiopathologic mechanisms.

The coronal facet orientation of L5–S1 and lumbosacral joint angle explains the reason why traumatic spondylolisthesis occurs mostly on L5–S1 level. It may be speculated that the weakness of the tip of this patient’s inferior articular process is the reason of L4–L5 traumatic spondylolisthesis.

Spondylolisthesis was classified by Wiltse et al. into dysplastik, isthmic, degenerative, pathologic and traumatic types []. Acute traumatic type is very rare and should be distinguished from acute isthmic spondylolisthesis, in which acute pars interarticularis fracture occurs probably due to a predisposed spondylolysis. Magnetic resonance imaging is mandatory to evaluate the integrity of disc content, ligamentous structure injury and neural compression.

In younger patients (under twenty years old), spondylolisthesis usually involves slippage of the fifth lumbar vertebra over the top of the sacrum. There are several reasons for this. First, the connection of L5 and the sacrum forms an angle that is tilted slightly forward, mainly because the top of the sacrum slopes forward. Second, the slight inward curve of the lumbar spine creates an additional forward tilt where L5 meets the sacrum. Finally, gravity attempts to pull L5 in a forward direction.
