Impact of Cement Placement and Leakage in Osteoporotic Vertebral Compression Fractures Followed by Percutaneous Vertebroplasty.
Retrospective study. ⋯ Neither extension of cement to the endplate nor cement leakage into the disk space had a significant impact on postprocedural pain. Furthermore, intradisk cement leakage was not a risk factor for new fracture after PVP in patients with OVCF. However, lower fill volumes should be used to lessen the risk of leakage.

A Comparative Biomechanical Analysis of Stand Alone Versus Facet Screw and Pedicle Screw Augmented Lateral Interbody Arthrodesis: An In Vitro Human Cadaveric Model.
Cadaveric biomechanical study. ⋯ Stand-alone interbody cage placement results in a significant reduction in acute ROM at the operative segment in the absence of posterior supplemental fixation. If added fixation is desired, facet screw placement, including the Viper F2 facet screw system using an integrated compression washer and transfacet-pedicular trajectory, provides similar acute stability to the spinal segment compared with traditional bilateral pedicle screw fixation in the setting of lateral interbody cage deployment.
