Spondylolysis and Spondylolisthesis - London Pain Clinic
Radiological evaluation is the definitive method of confirming the presence of spondylolysis and spondylolisthesis.
What is Spondylolisthesis / Spondylolysis
Spondylolisthesis is most often caused by spondylolysis. The cause of spondylolysis is not as clearly defined. Most believe it is due to a genetic weakness of the pars interarticularis. Both spondylolysis and spondylolisthesis can be present at birth or occur through injury. Repeated stress fractures caused by hyperextension of the back (as in gymnastics and football) and traumatic fractures are also causes. The most common cause in adults is degenerative arthritis.
Multiple logistic regression model was used to examine the association between LBP and spondylolysis, isthmic and degenerative spondylolisthesis, while adjusting for gender, age and BMI. The prevalence of those studied conditions in subjects with and without LBP was also compared. All statistical analyses were performed using SAS software, (SAS Institute Inc, Cary, North Carolina, release 9.1).
Spondylolisthesis, Spondylolysis, and Spondylosis
All readers were trained by an experienced research musculoskeletal radiologist (AG). An initial set of CTs were analyzed to develop a reading protocol for evaluation of spondylolysis and spondylolisthesis derived from the Meyerding classification. Using this protocol, the intra- and inter-rater reliability was calculated for two readers. All CT scans were then analyzed in blinded fashion. To evaluate for reader-drift, intra-rater reliability was periodically reassessed by inserting one repeated “reliability” scan for every 10 new scans. Before analyzing each new set of CT scans, 5 previously analyzed CTs were reevaluated to “recalibrate” the readings to a standard. The intra-observer reliability for identification of spondylolysis was 1.00. The inter-observer reliability was 0.98. For spondylolisthesis the intra-observer reliability varied at different levels between 0.95 and 1.00, and the inter-observer reliability ranged from 0.75 to 0.98. This range of kappa statistics represents good to excellent reproducibility.
Grading (I to IV) of spondylolisthesis (Meyerding classification) was estimated using sagittal reformations. Spondylolisthesis identified at a spinal segment with bilateral spondylolysis was considered isthmic spondylolisthesis. Spondylolisthesis observed in the absence of spondylolysis was considered degenerative spondylolisthesis. There were no individuals with spondylolisthesis associated with unilateral spondylolysis in the studied sample.

The aims of the present study were: 1) to evaluate the prevalence of spondylolysis, isthmic and degenerative spondylolisthesis in different age groups and at different lumbar spinal levels and according to sex in an adult community-based population; 2) to evaluate the association of spondylolysis, isthmic and degenerative spondylolisthesis with LBP in the same community-based cohort.
Spondylolisthesis was identified in 39 subjects, that is 20.7% of the studied population. 15 of 19 (79.0%) individuals with bilateral spondylolysis had associated spondylolisthesis. The prevalence of isthmic spondylolisthesis in our community-based sample was 8.2%. Spondylolysis in the absence of spondylolisthesis was found to be relatively uncommon. 4 of 19 subjects with bilateral spondylolysis (21.1%) demonstrated no measurable spondylolisthesis. One man demonstrated spondylolysis at two spinal levels, L4-L5 and L5-S1; but associated spondylolisthesis was observed only at the lower spinal level (L5-S1).

Given ongoing uncertainty regarding the true relationship between spondylolysis, spondylolisthesis, and development of LBP, evaluation and treatment patterns for these conditions remains highly varied. Initial attempts at conservative management are recommended and typically include a combination of activity modification, nonsteroidal anti-inflammatory medication, and physical therapy. Although there is some evidence that these patients respond similarly to patients without spondylolysis or spondylolisthesis, data regarding long-term clinical outcomes is lacking . Both diagnostic and therapeutic injections of the pars defect or local lumbar nerve root are frequently performed, but no clinical data regarding the utility of these measures has been reported. Indications for surgical treatment of these patients remain highly controversial.

The two major etiologies of spondylolisthesis are “isthmic” associated with spondylolysis and “degenerative” associated with degeneration of the posterior facet joints and/or intervertebral disc. Degenerative spondylolisthesis occurs mostly at the L4-5 level , as opposed to isthmic spondylolisthesis, which occurs most often at the lumbosacral level (L5-S1) . Isthmic spondylolisthesis appears in a majority of individuals with spondylolysis. 68% of first-graders with spondylolysis have been shown to have associated isthmic spondylolisthesis (Fredrickson et al. 1984). In another study, 80% of children with LBP and spondylolysis were found to have associated isthmic spondylolisthesis , .

A major deficit in current knowledge regarding the relationship between spondylolysis, spondylolisthesis, and LBP is the absence of reliable epidemiologic data investigating all three factors in an unselected community-based population. Previous studies have consisted almost entirely of radiographic reviews. In all cases, these studies either made no attempt to correlate radiographic findings with clinical symptoms or were derived from highly selected patient populations, i.e. patients presenting to a clinic for treatment of back pain. Moreover, the use of plain radiographs in these studies is highly problematic.

Lumbar spondylolysis and spondylolisthesis are often identified in the course of clinical evaluation of patients with low back pain (LBP). Spondylolysis is an anatomic defect in the vertebral pars interarticularis and is most commonly observed in the lowest lumbar vertebrae. Spondylolisthesis refers to displacement of a vertebral body on the one below it and has several etiologies, the most common being spondylolysis and spondylotic degeneration. Both spondylolysis and spondylolisthesis are prevalent in the general population, including a relatively high percentage of asymptomatic individuals; therefore, the relationship between these conditions and clinically significant LBP has been a subject of ongoing controversy.
