Larger screw on the concave side of apex pedicle: Friend or foe? Report on a rare cause of neurological deficit in scoliosis surgery

Indian Spine Journal, 2020
Pedicle screw instrumentation is currently the “gold standard” in scoliosis surgery. However, placement of pedicle screws in thoracic spine is considered challenging. Previous studies have described morphometric changes in the pedicle when a larger screw

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 ...

Placement of Thoracic Pedicle Screws [PDF]

JBJS Essential Surgical Techniques, 2016
Thoracic pedicle screws have become the spinal anchor of choice because of the superior biomechanics of this technique. It is widely used for the treatment of scoliosis, spinal deformity (such as kyphosis), trauma, tumors, infection, and other pathologies.

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

Biomechanical comparison of cervical transfacet pedicle screws versus pedicle screws

Chinese Medical Journal, 2008
Transfacet pedicle screws provide another alternative for standard pedicle screw placement for plate fixation in the lumbar spine. However, few studies looking at transfacet pedicle screw fixation in the cervical spine are available. Therefore, cervical transfacet pedicle screw fixation and standard pedicle screw fixation techniques were ...

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
