In addition to physiotherapy, he would require postural training to maintain correct posture and anti-inflammatory medication to decrease inflammation around the area of disc extrusion.

He should avoid bending at waist, lifting any weights especially while bending forward and avoid pulling or pushing things. MRI can detect a retrolisthesis even in lying down position though a standing lateral x ray gives a better idea regarding the extent of listhesis compared to MRI done in supine position.

In many cases, injury to the pars may initially occur in the teenage years and then go unnoticed for many years with chronic symptoms appearing later in life.

In addition to accidents, high-impact sports may also result in pars injuries.

The joints between the individual vertebrae allow for a range of movement which varies depending on location in the spinal column.

The joints are separated by the intervertebral discs which provide a cushioning effect and are held firmly in place by both the interlocking nature of the geometric shapes of the vertebrae and by strong ligaments.

A more comprehensive name for this condition is anterospondylolisthesis with the term spondylo indicating that the condition refers to the vertebrae.

Anterolisthesis is also commonly referred to as spondyolisthesis or simply listhesis but care should be taken to distinguish it from retrolisthesis which is a related condition in which the vertebral slippage occurs in a rearward direction.

Spinal injuries from accidental causes may result in anterolisthesis at any point of the spine, with the possible exception of the C1 and C2 vertebrae, but even with this cause, the L5-S1 junction is particularly vulnerable due to the very heavy mechanical loading at this point.

The spinal column is made up of many vertebrae which fit together in the manner of a three dimensional jigsaw puzzle.
