Origin of Isthmic Spondylolisthesis Isthmic spondylolisthesis has a multifactorial origin; mechanical, hereditary, and hormonal factors.
What is spondylolisthesis?Spondylolisthesis is a condition in which one bone in your back (vertebra).
Spondylolysis and spondylolisthesis are the most common causes of structural back pain in children.
Spondylolisthesis most commonly affects the lower lumbar spine, typically at the L4/5 or L5/S1 levels.
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.
Grade.2014 ICD-9-CM Diagnosis Code 756.12 Spondylolisthesis.
(9a) T1- and (9b) T2-weighted sagittal images in a patient with spondylolisthesis reveal clear pars defects (arrows). A horizontal configuration of the L5 neural foramina is readily apparent (red outline), with resultant foraminal stenosis. Compare this configuration with the normal keyhole appearance of the L4-5 foramina (blue outline). This horizontal configuration is typical in patients with spondylolisthesis due to spondylolysis.
revealed grade 1 spondylolisthesis of L4-L5 and L5-S1.
For posterior spinal decompression surgery to cause Spondylolysis or Spondylolisthesis, the surgery may occur any time before clinical onset of either condition.

Posterior spinal decompression surgery, at the level of the involved vertebra, prior to clinical onset or aggravation of Spondylolysis or Spondylolisthesis
My Lumbar Spinal Fusion for Spondylolisthesis L5 S1 - …
The T1-weighted off-midline sagittal image demonstrates a defect in the L5 pars interarticularis with interruption of the cortex and intermediate signal intensity material in the defect (arrow). Slight anterior subluxation of the L5 vertebral body is seen with respect to the S1 vertebral body. Marrow within the L5 posterior elements is of increased signal intensity on the T1 weighted images (arrowheads).
