Effect of pedicle screw augmentation with a self-curing elastomeric material under cranio-caudal cyclic loading—a cadaveric biomechanical study

Journal of Orthopaedic Surgery and Research, 2018
Background Pedicle screws can be augmented with polymethylmethacrylate (PMMA) cement through cannulated and fenestrated pedicle screws to improve screw anchorage. To overcome the drawbacks of PMMA, a modified augmentation technique applying a self-curing

Evaluation of the Intrinsic Properties of Pedicle Screws: Do Diameter, Manufacturing and Screw Design Affect Resistance and/or Resistivity

Biomolecules & Biomedicine, 2009
The pedicle screw diameter, composite and design are variables that can affect the threshold of intraoperative electromyographic monitoring. Even though we know that larger diameter objects tend to have less resistance, no study documented the effect ...
