Clinical data compared between two groups
| Prevention group | Non-prevention group | P-values | |
|---|---|---|---|
| Patient, n | 18 | 37 | |
| Mean age, y | 74.89 ± 6.18 | 75.51 ± 8.71 | 0.787 |
| Sex, No. F:M | 15:3 | 30:7 | 0.774 |
| Mean height, m | 1.60 ± 0.79 | 1.61 ± 0.83 | 0.703 |
| Mean weight, kg | 59.16 ± 7.92 | 58.19 ± 8.98 | 0.695 |
| Mean BMI, kg/m2 | 23.03 ± 2.10 | 22.46 ± 3.08 | 0.471 |
| L1–4 mean BMD | 0.678 ± 0.118 | 0.691 ± 0.127 | 0.769 |
| Hip total BMD | 0.601 ± 0.120 | 0.641 ± 0.269 | 0.604 |
| Cement disk leakage, n | 3 | 8 | 0.666 |
| Sandwich vertebra, n | 24 | 47 | |
| Thoracic–lumbar, n | 17 | 32 | 0.813 |
| Cobb angle of SV | 5.28 ± 3.62 | 3.92 ± 3.17 | 0.195 |
| Compression rate of SV | 0.90 ± 0.10 | 0.93 ± 0.07 | 0.107 |
No significance between two groups. BMI, body mass index; BMD, bone mineral density; SV, sandwich vertebra. Cobb angle and compression rate of sandwich vertebra were measured by lateral spinal radiographs within 1 day after procedure.
