Accuracy of ‘O arm’ guided pedicle screw placement in osteoporotic spine with the ‘precious pedicle’
Interdisciplinary Neurosurgery, 2022 Introduction: Osteoporosis is a global burden with the prevelance ranging from 15 to 20% in women and 4–7% in men across the globe. This is the age group which most commonly presents in spine clinic with pathologies requiring pedicle screw fixation ...

Evaluation of the accuracy of mobile cone-beam computed tomography after spinal instrumentation surgery [PDF]
Journal of Trauma and Injury, 2022 Purpose Pedicle screw fixation provides 3-column stabilization, multidimensional control, and a higher rate of interbody fusion. Although computed tomography (CT) is recommended for the postoperative assessment of pedicle screw fixation, its use is ...

The Effect of Thoracolumbar Pedicle Isthmus on Pedicle Screw Accuracy [PDF]
Global Spine Journal, 2019 Study Design: Retrospective analysis. Objectives: Aberrant pedicle screws can cause serious neurovascular complications. We propose that a predominant factor of pedicle screw breach is the vertebral anatomy at a given spinal level.

Immediate stabilization of pedicle screws
Current Directions in Biomedical Engineering, 2023 Abstract This study was designed as proof of principle and safety test of the novel technique, the Immediate Stabilization System (ISS). The technique is designed to immediately stabilize polymer-augmented pedicle screws (PAS) in deficient bone and avoid complications of loosening pedicle screws at the bone-screw interface, especially in

Bone density optimized pedicle screw insertion
Frontiers in Bioengineering and Biotechnology, 2023 Background: Spinal fusion is the most common surgical treatment for the management of degenerative spinal disease. However, complications such as screw loosening lead to painful pseudoarthrosis, and are a common reason for revision. Optimization of screw
