Objective:The aim of this study is to investigate the relationship between sagittal balance, spinopelvic parameters, bone mineral density, balance, and falls efficacy in postmenopausal osteoporosis patients.Materials and Methods:Forty patients between the ages of 40-80 with a diagnosis of postmenopausal osteoporosis were included in the study. Spinopelvic parameters (sagittal vertical axis (SVA), thoracic kyphosis, lumbar lordosis, pelvic tilt, pelvic incidence, sacral slope) were calculated from spine radiographs. Patients were applied Tinetti Balance and Gait Assessment and Falls Efficacy Scale. Relationship between bone mineral density measurements, clinical parameters, spinopelvic parameters, balance and gait, and falls efficacy were investigated.Results:Mean age of the patients was 63.42±8.98 and the mean L1-L4 T score was 2.5±0.68. Statistically significant negative correlation was found between the L1-L4 and L2-L4 vertebrae bone mineral density and T score, and sacral slope. Negative statistical correlations were found between SVA and Tinetti Balance and Gait Assessment balance subtest and total scores. There was no statistically significant relationship with other spinopelvic parameters. There was no significant correlation between SVA and spinopelvic parameters and Falls Efficacy Scale, while a statistically significant negative correlation detected between Falls Efficacy Scale and Tinetti Balance and Gait Assessment balance and gait subtests and total scores. Among the patients with normal, mild and severe deformity sagittal balance, there was statistically significant difference in terms of Tinetti Balance and Gait Assessment balance and gait subtests scores and total scores, while there was no difference with regards to Falls Efficacy Scale.Conclusion:In postmenopausal women with osteoporosis, SVA, sagittal balance parameters, and balance and gait functions were found to be associated.

Objective: Spinopelvic parameters were identified and the association between sagittal spinopelvic alignment and lumbar disc diseases have been reported in several studies. The purpose of this study was to evaluate the spinopelvic parameters such as lumbar lordosis (LL) and sacral slope (SS) in normal healthy lumbar spine versus degenerative disc disease group Methods: We retrospectively identified 140 patients suffered from back pain with/without radiculopathy between 2016-2017 in this study. Of these 70 patients had normal disc morphology called control group, and the other 70 patients had lumbar degenerative disc disease called disease group. All patients' LL, and SS angles were measured on T2 weighted sagittal magnetic resonance imaging and degenerated disc levels were noted. We also recorded LL divided by SS value as LL-SS ratio in both group. We compared these parameters between two groups. Results: In disease group there was a positive correlation (r=0.947, p<0.0001) between the LL and SS angles. The mean LL was 45.14± 11.01 and the mean SS angle was 35.91±7.67 degrees. and there was weak negative correlation between degenerated disc level and SS angle (r=-0.243, p=0.042). LL-SS ratio was 1.25±0.1. In control group, there was a positive correlation (r=0.927, p<0.0001) between the LL and SS angles. The mean LL was 49.46±9.07 and the mean SS was 38.45±6.91 degrees. LL-SS ratio was 1.28±0.93 There were significant differences in LL, SS and LL-SS ratio between groups (p=0.013, p=0.041, p=0.025 respectively) Conclusion: LL, SS angles and LL-SS ratio which are easily measured at neurosurgery, orthopaedics and physical therapy practice, may be the predictor of disc degeneration.
