The overall purpose of conducting this study is to evaluate the safety and efficacy of V-Flex and V-Steady for augmentation of osteoporotic vertebral compression fractures and to verify that adding a cement softener into a PMMA bone cement is comparable to a PMMA bone cement alone (V-Steady).

* Maximum of 1 level of vertebral compression fractures eligible for treatment localized at level Th5 to L5 and verified by MRI or bone scan;
* Height reduction of the affected vertebra(e) with an anterior wall compression of not exceeding 60% compared to the nearest normal vertebral body determined by X-ray;
* Have pain correlating to the fractured levels requiring regular analgesic intake and/or causing substantial disability of daily life;
* Pain score ≥ 40 mm measured by VAS correlating to at least one of the fracture levels (scale 0 - 100 mm) at the screening visit;
