The Effects of Bone Cement Volume in Percutaneous Vertebroplasty for Thoracolumbar Junction Vertebral Compression Fractures: A Clinical Comparative Study

Table 3

The IDL, STVF, and SAVF in respective groups with different volumes of cement.

	≤5 mL	>5 mL	RR	value
IDL	13/146	22/170	1.45	0.250
STVF	4/146	14/170	3.01	0.036
SAVF	2/146	10/170	4.29	0.029

IDL: intervertebral disc leakage; STVF: subsequent total vertebral fracture; SAVF: subsequent adjacent vertebral fracture; RR: relative risk.
