Comparative Biomechanical Evaluation of Cement Augmentation Techniques for Pedicle Screw Fixation in Osteoporotic Vertebrae: A Cadaveric Study
Pedicle screw fixation is widely used in spinal surgery to achieve mechanical stability. However, in osteoporotic bone, reduced bone mineral density compromises screw anchorage, increasing the risk of loosening and failure. The main objective of the study was to compare the biomechanical performance, including pu...
