Fig. 2

The developed nomogram of new vertebral compression fractures after vertebral augmentation. Mark the values at each factor axis, acquire the corresponding points at the points axis, and sum up the points of all factors. Mark the total points on the total point axis and draw a perpendicular line towards the risk of leakage axis. The value on the bottom line gives the probability of the cement leakage. Note: The nomogram of postoperative VCFs was developed in training cohort, including age, bone cement dosage, bone cement leakage, bone cement dispersion, contact between bone cement and endplate, and available anti-osteoporosis treatment
