In children, only 13% of those with spondylolysis have symptoms.
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:
Spondylolysis and Spondylolisthesis | Clinical Gate
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.
