Spondylolisthesis - PhysioWorks
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.
Type I. Dysplastic: This type results from congenital abnormalities of the upper sacral facets or inferior facets of the fifth lumbar vertebra that allow slipping of L5 on S1. There is no pars interarticularis defect in this type. The sacrum is not strong enough to withstand the weight and stress. Thus, the pars and inferior facets of L5 are deformed. If the pars elongates, it is impossible to differentiate it by x-ray from the isthmic (type II b) Spondylolisthesis. If the pars separates, it becomes impossible to differentiate it by x-ray from the isthmic lytic (type II a) Spondylolisthesis. This type is also associated with sacral and neural arch deficiencies. It has a familial tendency.
Isthmic vs Degenerative Spondylolisthesis
Type II. Isthmic: This type results from a defect in the pars interarticularis that allows forward slipping of L5 on S1. Three types of isthmic spondylolistheses are recognized:
Nonsurgical treatment for spondylolisthesis commonly involves physical therapy. Your doctor may recommend that you work with a physical therapist a few times each week for four to six weeks. In some cases, patients may need a few additional weeks of care.
Spondylolisthesis: Symptoms, Causes, and Treatment
For patients with certain conditions, abnormal and excessive motion at a vertebral segment may result in pain. When this abnormal motion from an unstable or degenerated vertebral segment causes unnecessary pain, Dr. Pablo Pazmino may recommend an all Anterior approach to decrease pain at this area. The latest stand-alone anterior lumbar fusion cage implant used in spinal surgery from Surgicraft is manufactured from biocompatible polyetheretherketone (PEEK-OPTIMA, Invibio Ltd, Thornton, UK). The benefits this implant offers include reduced operating times, better bone fusion, restoration of height, and improved spinal alignment. In mechanics, Young's modulus (E) is a measure of the stiffness of a given material. The Young's Modulus of PEEK is similar to that of cortical bone, therefore, it offers more elasticity than metal. It can absorb energy, handle the normal weight of the body and minimize stress on adjacent levels. The material is also radiolucent (unseen on X-rays) and thereby allows an improved view of the fusion mass that is taking place. However, to be able to offer X-ray (computer tomography or magnetic resonance) imaging for optimal positioning and postoperative assessments, titanium trace wires are press fitted into the implant. Recovery for the patient is faster in many cases. Some patients need to be operated on from the back. However, the implant can be inserted through the patient's stomach where reconstructing the spine is much less invasive. Some patients only need a small incision from the front or side, and in these cases recovery can be rapid, requiring only a two- or four-day hospital stay followed by a period of recuperation to allow for fusion to occur. Immobilizing painful movement in a specific area of the lumbar spine should decrease pain generated from the degenerated discs and arthritic joints. All lumbar spinal fusion surgery involves adding bone graft, or bone graft substitutes which stimulate a biological response that causes the nearby bone to weld or fuse. Upon successful fusion, the two vertebral segments stop all painful motion, and patients can return to their activities of daily living.
Most spondylolytic defects and cases of Spondylolisthesis are congenital. The prevalence of Spondylolisthesis in the general population is about 5% and is about equal in men and women. Spondylolysis and Spondylolisthesis most frequently involve L5, although L4 can also be affected and, rarely, more proximal levels.

Degenerative changes in the spine (those from wear and tear) can also lead to spondylolisthesis. The spine ages and wears over time, much like hair turns gray. These changes affect the structures that normally support healthy spine alignment. Degeneration in the disc and facet joints of a spinal segment causes the vertebrae to move more than they should. The segment becomes loose, and the added movement takes a additional toll on the structures of the spine. The disc weakens, pressing the facet joints together. Eventually, the support from the facet joints becomes ineffective, and the top vertebra slides forward. Spondylolisthesis from degeneration usually affects people over 40 years old. It mainly involves slippage of L4 over L5.

In younger patients (under twenty years old), spondylolisthesis usually involves slippage of the fifth lumbar vertebra over the top of the sacrum. There are several reasons for this. First, the connection of L5 and the sacrum forms an angle that is tilted slightly forward, mainly because the top of the sacrum slopes forward. Second, the slight inward curve of the lumbar spine creates an additional forward tilt where L5 meets the sacrum. Finally, gravity attempts to pull L5 in a forward direction.
