The level of the Spondylolysis/Spondylolisthesis must be identified.

Spondylolysis and Spondylolisthesis usually cause no symptoms in children; however, many seek medical evaluation because of a postural deformity or gait abnormality. Pain most often occurs during the adolescent growth spurt and is predominantly backache, with only occasional leg pain. Symptoms are exacerbated by high activity levels or competitive sports and are diminished by activity restriction and rest. The back pain probably results from instability of the affected segment, and the leg pain is usually related to irritation of the L5 nerve root.

Congenital for Spondylolysis or Spondylolisthesis

In spondylolysis, there is usually no need to consider surgical intervention.

Spondylolysis, in most cases, is congenital.

Degeneration of the lumbar spine is described as lumbar spondylosis or degenerative disc disease.
Spondylolisthesis, spondylolysis, and spondylosis.

Spondylolisthesis, lumbar region.

Isthmic spondylolisthesis (type Up to 5.8% of men and 9.1% of women are believed to have this type of listhesis.
Spondylolysis and Spondylolisthesis.

2: Normal L5 on S1 presentation (left) and Grade 1 spondylolisthesis of L5 on S1 (right).

Anterolisthesis vs spondylolisthesis - Doctor answers

Subtype A :A fatigue fracture of the pars interarticularis. Subtype B :There is elongation of the pars interarticularis without a defect. Subtype C :Rare, due to severe hyperextention leading to acute pars fractures.

Anterolisthesis vs spondylolisthesis - What causes spondylolisthesis

Acute traumatic fractures only involving the pars are rare, and certain disease processes which weaken the bone such as Osteopetrosis can cause spondylolysis.

Spondylolisthesis is the slippage of one vertebrae over another

Also known as degenerative spondylolisthesis with an intact neural arch ie non spondylolytic spondylolisthesis. This is 10 times more common at L4, and no greater than 25% anterior displacement occurs.

The following is a classification of Spondylolisthesis and Spondylolysis according to cause:

Spondylolysis spondylolisthesis Overview.

MR imaging using parasagittal T2-weighted and axial T1 and T2- weighted images through the area of the pedicle / pars junction may demonstrate bone marrow oedema present in active spondylolysis. For the demonstration of an interruption in the pars interarticularis sagittal T1 and proton density studies which show better differentiation between cortical and medullary bone are more useful.

Repetitive trauma in clinical onset or aggravation of Spondylolisthesis and/or Spondylolysis

Anterolisthesis in the cervical spine--spondylolysis.

It is interesting to note that, in cricket, the bowling action seen in fast bowlers involves rotation and extension, often resulting in a stress fracture/spondylolysis on the opposite side to the bowling arm.

Spondylolysis is classified as dysplasic.Spondylolysis spondylolisthesis Overview.

Spondylolisthesis, Spondylolysis, and Spondylosis

Data from the Spine Outcomes Research Trial (SPORT) study were analyzed to determine if duration of symptoms affects outcomes after treatment of spinal stenosis or degenerative spondylolisthesis.[14] In spinal stenosis patients with symptoms for more than 12 months, outcomes were worse compared with spinal stenosis patients with symptoms for fewer than 12 months, who experienced significantly better surgical and nonsurgical treatment outcomes. On the same basis of symptom duration before treatment, no differences were noted in outcomes for degenerative spondylolisthesis patients.
