Objective To understand the characteristics of sagittal parameters of spino-pelvic in patients with Lumbar disc herniation (LDH), explore the differences of sagittal parameters in age and sex, and evaluate the correlation between sagittal parameters of spino-pelvic and healthy life quality in patients with Lumbar disc herniation.
Methods A retrospective analysis was made on the spinal surgery in the orthopaedic hospital of Tangdu hospital of the fourth military medical university. From January 2016 to September 2018, 120 patients with lumbar disc herniation were admitted to the hospital. On the full-length radiographs, we measured pelvic incidence (pelvic incidence, PI), pelvic tilt Angle (pelvic tilt, PT), sacral slope Angle (sacral slope, SS), thoracic kyphosis(TK), lumbar lordosis Angle (lumbar lordosis, LL), PI-LL matching values, sagittal plane vertical axis (sagittal vertical axis, SVA) and collates records ODI values. The differences of sagittal parameters were compared according to gender and age group, and the correlation between sagittal parameters and ODI values was analyzed.
Results There was no significant difference in age, TK, LL, SVA, PI, PT, SS, PI-LL between male and female in patients with Lumbar disc herniation. The comparison of ODI values between male and female showed that male ODI was 46.94±20.09, female ODI was 55.92±21.26, which is significant differences (
P=0.020).
Conclusion There was no statistical difference in the sagittal parameters of the spino-pelvic between different genders and ages of LDH patients. However, the PI of female patients with LDH have a significantly larger trend. Further research is needed. There was no correlation between the spino-pelvic sagittal parameters and quality of life in patients with lumbar disc herniation. The poor quality of life of female patients with LDH in this study has no significant correlation with PI, but further research is needed to confirm it according to previous reports.
