Objective To analyze the risk factors of lumbar spondylolysis, and provide reference for prevention and treatment of lumbar spondylolysis. Methods The body mass index, exercise intensity, spinal dysplasia and related spinal-pelvic structure parameters of 88 patients with slipping prophase L5 spondylolysis were analyzed. A control group with 88 normal volunteers were recruited in this study, and the corresponding indicators between two groups were statistically processed. Results There were statistical differences in relative metabolic rate, pedicle-facet angle, pelvic incidence angle, lumbar lordosis angle, lumbar isthmic width, lumbar sacralization, spina bifida occulta and family history between the slipping prophase lumbar spondylolisthesis group and the control group (P<0.05). Logistic regression analysis showed that relative metabolic rate, pedicle-facet angle, pelvic incidence angle and lumbar isthmic width were the risk factors for lumbar spondylolysis. Conclusion The occurrence of lumbar spondylolysis is related to many factors. A comprehensive understanding of its associated risk factors is helpful in reduction of its incidence and prevention its further development into slip.
