Pullout Strength after Expandable Polymethylmethacrylate Transpedicular Screw Augmentation for Pedicle Screw Loosening

Journal of Korean Neurosurgical Society, 2015
Pedicle screw fixation for spine arthrodesis is a useful procedure for the treatment of spinal disorders. However, instrument failure often occurs, and pedicle screw loosening is the initial step of a range of complications. The authors recently used a modified transpedicular polymethylmethacrylate (PMMA) screw augmentation technique to overcome ...

Investigation on pullout strength between different design of cannulated pedicle screw and osteoporosis bones to obtain an optimum design [PDF]

, 2019
Pedicle screws are widely used for the treatment of spinal instability by spine fusion. This treatment can be performed at any level in the spine (cervical, thoracic or lumbar) and prevents any movement between the fused vertebrae.

Effect of Insertional Direction of Pedicle Screw on Screw Loosening: A Biomechanical Study on Synthetic Bone Vertebra under a Physiology‐like Load

Orthopaedic Surgery
Objectives It is now understood that pedicle screw loosening at the implant‐bone interface can lead to poor screw–bone interface purchase and decreased fixation stability. Previous biomechanical tests used cadaveric vertebrae and pull‐out or torque loads

Iliosacral Screw Fixation for Treating Sacral Fractures: A Modified Pedicle‐Guided Fixation Technique in Prone Position

Orthopaedic Surgery, Volume 18, Issue 11, Page 2480-2490, November 2026.
Modified pedicle‐guided fixation technique for iliosacral screw placement in prone position reduces operation time and radiation exposure as conventional two‐dimensional fluoroscopy was enough to identify safe insertion corridors. Prone position is also advantageous when dealing with obese patients and concomitant spinal injuries.
