Outcomes of Augmentation in Osteoporotic Vertebral Compression Fractures Showing a Cleft Sign on MRI.

Vertebral augmentation is effective for treating OVCFs with gas- or liquid-filled IVCs. However, in patients with gas-filled IVCs, PKP may be associated with higher incidence of cement leakage and recollapse of treated vertebrae than PVP. Liquid-filled IVCs may not promote bone cement distribution.
