Computed tomography-based navigation-assisted pedicle screw insertion for thoracic and lumbar spine fractures.
BACKGROUND Incorrect placement of pedicle screws may lead to neurovascular injury, so the position is important for the reduction of spinal fractures. CT-based image-guided surgery has been promoted as a means to theoretically improve the accuracy of pedicle screw placement. Patients who underwent CT-based navigation-assisted pedicle screw fixation for thoracic or lumbar fractures were reviewed...
متن کاملNovel Landmark for Cervical Pedicle Screw Insertion Point from Computed Tomography-Based Study
STUDY DESIGN Cross-sectional study. PURPOSE The purpose of this study was to evaluate a novel landmark for the cervical pedicle screw insertion point. OVERVIEW OF LITERATURE To improve the accuracy of pedicle screw placement, several studies have employed the lateral mass, lateral vertical notch, and/or inferior articular process as landmarks; however, we often encounter patients in whom we...
متن کاملPercutaneous ilio-sacral screw insertion. fluoroscopic techniques.
Unstable pelvic ring fractures raise treatment challenges in severely injured patients. Ilio-sacral screw fixation is an elegant option for stabilising the posterior lesion, which is a common source of residual pain. This technique provides secure fixation. The first description can be found in a 1913 treatise by Lambotte [1]. In 1978, Letournel reported the treatment of sacro-iliac joint dislo...
متن کاملAccuracy of Percutaneous Lumbosacral Pedicle Screw Placement Using the Oblique Fluoroscopic View Based on Computed Tomography Evaluations
STUDY DESIGN Retrospective. PURPOSE This study aims to investigate the accuracy of the oblique fluoroscopic view, based on preoperative computed tomography (CT) images for accurate placement of lumbosacral percutaneous pedicle screws (PPS). OVERVIEW OF LITERATURE Although PPS misplacement has been reported as one of the main complications in minimally invasive spine surgery, there is no com...
متن کاملGuided pedicle screw insertion: techniques and training.
BACKGROUND CONTEXT In spinal fusion surgery, the accuracy with which screws are inserted in the pedicle has a direct effect on the surgical outcome. Accurate placement generally involves considerable judgmental skills that have been developed through a lengthy training process. Because the impact of misaligning one or more pedicle screws can directly affect patient safety, a number of navigatio...
