In Brief Study Design. Evaluation of a novel, leakage-free vertebroplastic instrumentation by fresh cadaveric studies. Objectives. To compare Vessel-X, novel percutaneous bone void filling container system, with conventional kyphoplasty in restoring strength, stiffness, and height experimentally induced vertebral compressive fractures morphologically determine the cement distribution. Summary Background Data. Clinically, both vertebroplasty perform well reinforcement pain relief. One shortcomings, however, is risk leakage. Vessel-X expander filler combined for augmentation requiring evaluation. Methods. A total 28 fresh-frozen specimens were randomly assigned to 4 groups testing: unipedicular kyphoplsty, bipedicular Vessel-X. Compressive created on each vertebra after determining mineral density. Kyphoplasty performed using bioactive (SrHAC) under C-arm fluoroscopy compared compression testing measure effects augmentation. Morphologic observations also distribution restoration. Results. There was no significant difference density, initial stiffness any groups. Furthermore, observed volume intragroup comparison within or could expand contain most cement. The restoration ranged from 88.5% 96.4% all augmented strength injections reached 3651.57 N 4833.73 N, respectively. Stiffness injection significantly higher than that injection. Conclusion. comparable mechanical properties fractured vertebrae. Interestingly, showed considerably less leakage better placement body. Therefore, it be controllable technique system vertebrae expanded effective control. This study indicated
