In cases of bilateral pars interarticularis defects, there is the potential for anterior or posterior spondylolisthesis (the slipping of one vertebral body relative to the adjacent segment). Spondylolisthesis can be graded based upon the percent degree of displacement of one vertebral body compared to the other.
Pars defects (spondylolysis) subdivide into five categories according to the Wiltse-Newman Classification[22]: Dysplastic: congenital abnormalities/attenuated pars (approximately 20%) Isthmic:lesions in the pars resulting from a stress fracture or acute fractures (approximately 50%) Type II-A:pars fatigue fracture

A pars defect or spondylolysis is a stress fracture of the bones of the lower spine. These fractures typically occur due to overuse. They can be on one or both sides of the vertebrae. It is a common cause of low back pain in children and adolescents.
Fatigue fracture of vertebra, lumbar region, initial encounter for fracture. M48. 46XA is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2022 edition of ICD-10-CM M48.
What is the difference between spondylolysis and spondylolisthesis? These are separate but sometimes related conditions. Spondylolysis is a type of spine fracture, while spondylolisthesis is an incorrect movement and positioning of spine vertebrae.
Pars defect. Stress fracture. These three terms are used interchangeably, all referring to the same condition. Spondylolysis is a stress fracture through the pars interarticularis of the lumbar vertebrae.
Causes of a pars defect: The break in the bone occurs due to undue pressure on the pars interarticularis which can be linked to activities which cause repeated stress and strain. These may include (but not limited to): Gymnastics, athletics, diving due to hyperextension and/or extreme twisting.

Fracture of lumbar vertebra ICD-10-CM S32. 009A is grouped within Diagnostic Related Group(s) (MS-DRG v39.0):
Spondylolysis is a breakdown or fracture of the narrow bridge between the upper and lower facets, called the pars interarticularis. It can occur on one side (unilateral) or both sides (bilateral) and at any level of the spine, but most often at the fourth or fifth lumbar vertebra (Fig. 2).
Spondylosis involves the separation of the pars interarticularis. In contrast, spondylolisthesis is defined by a slipped vertebra. When one bone of the spine slips forward over another, it causes damage to the spinal structure. In some cases, a stress fracture may be to blame.
About Pars Defect A pars defect is also called a pars fracture or spondylolysis. Some pars defects are congenital, existing at birth, but others are caused by repetitive stress and strain to the lumbar spine that can take place during adolescence. It can cause back pain, sometimes severe enough to require surgery.
