Study DesignRetrospective chart review.ObjectiveTo determine the effect of conservative measures on radiographic outcomes in those with isolated spondylolysis.Summary Of Background DataSpondylolysis is a common cause of low back pain in pediatric patients, affecting between 4.4% and 4.7% of all pediatric patients. This rate is even higher in high-level athletes, with recent studies suggesting a rate of 47% in this population. Conservative measures are recommended for treating symptomatic spondylolysis and are effective in controlling symptoms, but there is little evidence regarding their effect on radiographic outcomes.MethodsA retrospective review was conducted of patients diagnosed with spondylolysis who were treated at a single academic institution between January 1, 2012, and January 1, 2022. Data collected included demographics, presentation characteristics, pretreatment and post-treatment radiologic findings, types of treatments employed, and final symptomatic status at follow-up. The Student t test and the Wilcoxon rank sum test were used to compare continuous variables. The χ 2 test was used to compare categorical variables.ResultsA total of 119 patients were included in the study. There was an 81.5% rate of healing on advanced imaging for those treated with conservative measures. When comparing those with healing on advanced imaging to those without, those with healing were more likely to have an acute fracture ( P= 0.04), have symptomatic improvement ( P <0.01), and return-to-play ( P= 0.02) compared with those without. Those with healing also had an odds ratio of 6.9 ( P <0.01) and 4.5 ( P =0.02) to achieve symptomatic improvement and return to their sport, respectively, compared with those who did not.ConclusionOur study found those with isolated spondylolysis who were treated with conservative measures had a high healing rate on advanced imaging and those with healing had significantly higher odds of having symptomatic improvement and returning to play compared with those without.Level Of Evidence4.Copyright © 2024 Wolters Kluwer Health, Inc.
