Material and Method: We retrospectively searched our data to find out patients who had one sided, one level and only one spinal surgical intervention for herniated lumbar disc. Results: Among 796 cases, 336 (4256) were men and 460 (5831:) were women. The level of the pathology is determined as LI - 2 for 4 cases (0.56b), L2 - 3 for 15 cases (1.9%), L3 - 4 for 5 I cases (6.4%), L4 - 5 for 412 cases (51.8%) and as L5 - 51 on 314 cases (39.4%). While a total of 70 cases (8.9%) were identified on upper -levels ( LI - 2. L2 - 3, L3 - 4); 726 cases (91.1%) were found to be on lower -levels ( L4 - 5, L5 - Si). A mild positive correlation between the pathology level and physical activity intensity (P e 0.05, P = 0.103) has been demonstrated: as well as a strong negative correlation between pathology level and mean age (P < 0.05. P = -0.404). Discussion: The demographic characteristics are consistent with the literature. Physical activity intensity influence on lower -level herniations might have significance due to the large sample size. The strong negative correlation between pathology level and mean age suggests that the degeneration raises the frequency of upper -level herniations.en10.4328/JCAM.3068info:eu-repo/semantics/openAccessIntervertebral Disc DiseaseDiscectomyDemographic AnalysisLow-Back-PainRisk FactorArticle75585588N/AWOS:0004106182000012-s2.0-84983316567N/A222471
