A PubMed search of spondylolysis or spondylolis-thesis yielded over 800 citations. Sixty-eight articles were selected based on an opinion of perceived relevance to the subjects of spondylolysis and spondylolisthesis.

In children, only 13% of those with spondylolysis have symptoms.

The level of the Spondylolysis/Spondylolisthesis must be identified.

Congenital for Spondylolysis or Spondylolisthesis

Posterior spinal fusion means a surgical procedure involving immobilization of the posterior elements of two or more vertebrae by the use of bone grafting, in the absence of immobilization of the lateral elements, of the same vertebrae. This type of surgery produces an abnormality in the functional loading of the adjacent vertebrae, and can result in either Spondylolysis or Spondylolisthesis.

Spondylolysis, in most cases, is congenital.

Severe trauma to the lumbar spine means a major, high impact, direct injury to the lumbar spine which produces immediate lumbar pain and precludes unaided ambulation for a period of at least 2 weeks, and is associated with other fractures and/or significant soft tissue injuries. Examples are as follows:

Although this subtype has a strong hereditary tendency, it makes up only half of the dysplastic group. The elongated pars (subtype b) is believed to result from micro fractures that heal with an elongated pars rather than from a lytic lesion. Acute pars fractures (subtype c) always result from significant trauma; these are rare and most frequently occur with Spondylolysis rather than with Spondylolisthesis.

CHAPTER 27 Spondylolysis and Spondylolisthesis

As with spondylolysis, sporting activities that involve repetitive loading of the spine into flexion and/or extension, combined with rotation, places the lumbar spine at risk of developing a spondylolisthesis.

Spondylolysis and Spondylolisthesis of the Lumbar …

Spondylolysis is a defect in the spine that involves weakness within the vertebrae and the facet joints, which connect all of the vertebrae together. This weakness often results in stress fractures within the vertebrae, or the bones slipping out of place, a condition known as spondylolisthesis. The cause of spondylolysis has been linked to genetic factors as well as repetitive trauma, although the specific cause is still unknown.

Spondylolytic spondylolisthesis exercises

For severe trauma to the vertebral spine to cause or aggravate Spondylolysis or Spondylolisthesis, the following criteria should be met:

Spondylolisthesis, Spondylolysis - Radsource

For posterior spinal decompression surgery to aggravate Spondylolysis or Spondylolisthesis, signs/symptoms of Spondylolysis or Spondylolisthesis should occur within 10 years of the surgery.

The lytic (subtype a) results from the separation or dissolution of the pars. The incidence of this type of Spondylolisthesis increases from less than 1 percent in children 5 years of age to 4.5 percent in children 7 years of age. The remaining 0.8 to 1 percent increase occurs between the ages of 11 to 16 years, presumably because of stress fractures caused by athletic activity. Extension movements of the spine, with lateral flexion, can increase the shearing stress at the pars interarticularis and result in Spondylolysis.
