OBJECTIVES: To determine the prevalence rate of spondylolysis in an unselected adult community‐based populations in Korea and to evaluate the association of spondylolysis with low back pain (LBP).
SUMMARY OF BACKGROUND DATA: Spondylolysis is prevalent in general population; however, the prevalence of spondylolysis and its relationship with LBP is controversial in Korean population.
METHODS AND MATERIALS: A sample of eight hundred fifty five participants (age: 20 to 86 years) from our medical center and who underwent multidetector CT imaging to assess abdominal and urological lesions were included in this study. The occurrence of LBP needed medication in the preceding 12 months was evaluated using a self‐report questionnaire (a modified Nordic Low Back Pain Questionnaire). The presence of spondylolysis was characterized by the CT imaging. We used multiple logistic regression models to examine the association between spondylolysis and LBP, while adjusting for gender and age.
RESULTS: Seventy‐eight study subjects (9.12%) demonstrated spondylolysis on the CT imaging. There is statistically significant difference among gender(p=0.033) but no statistically significant difference among age group(p=0.177). Three hundred eleven study subjects (36.37%) had back pain. There is statistically significant difference among gender(p=0.001). No significant association was identified between spondylolysis and the occurrence of LBP.
CONCLUSIONS: The prevalence of LBP is 36.37% and the prevalence of lumbar spondylolysis based on the CT imaging is 9.12% among an unselected communitybased Korean population. Male demonstrated a significantly greater presence of LBP compared to female(p=0.001) and a significantly greater of presence of spondylolysis(p=0.033).
The prevalence rate of spondylolysis demonstrated no significant association with the presence of LBP and age group in adulthood.
