ObjectiveTo verify whether Scheuermann's disease (SD) is a risk factor for patients with recurrent lumbar disc herniation (rLDH) than in patients without recurrence.Study DesignCase-control study.Place And Duration Of StudyDepartment of Orthopaedics, Yantaishan Hospital, China, from December 2016 to September 2019.MethodologyThe demographics (age, gender, body mass index [BMI], alcohol abuse, and current smoking), diabetes mellitus, and radiological data (affected levels, herniated side, herniation type, Pfirrmann grade, and the presence of SD) of 602 patients were retrospectively analysed, who underwent surgery for symptomatic LDH from December 2016 to August 2018. They were underwent one-year follow-up and were divided into LDH and rLDH groups. Both typical and atypical SD criteria were used to diagnose SD. Independent-sample t-test was used to analyse the role of age and BMI in both groups, and the Chi-square test was conducted to analyse other parameters. Logistic regression analysis was performed to evaluate various factors.ResultsThere was a significant difference in age (p=0.026), BMI (p=0.007), current smoking (p=0.001), and SD (p<0.001) between the groups. When these parameters were included in the logistic regression analysis, age, current smoking status, and SD were found to be risk factors for rLDH.ConclusionAge, current smoking, and SD are risk factors for rLDH. Older patients with radiological characteristics of SD should quit smoking to prevent rLDH. Key Words: Scheuermann's disease, Kyphosis, Disc herniation, Recurrence, Age, Smoking, Risk factor.
