Complications of the Pedicular Screw System Used for Spinal Disorders.

Accuracy Assessment of Freehand Pedicular Screw Placement

Background: The purpose of this prospective study was to determine the accuracy of pedicular screw insertion withoutthe use of fluoroscopy.Methods: This study was conducted on patients with spinal diseases in need of pedicular screw fixation and fusion.The included patients suffered from such conditions as vertebral fracture, spinal stenosis, kyphosis, tumor, and pelvicf...

Anatomical considerations for insertion of pedicular screw in cervicothoracic junction

Background: This study aimed to investigate the pedicle dimension and angulation in cervicothoracic junction (CTJ) using the findings of computed tomographic (CT) to help accurate insertion of pedicular screw. Methods: Forty three patients with high quality CT images of CTJ were evaluated. Pedicle width (PW), pedicle height (PH), pedicle axis length (PAL), transverse angle (TA) and sagittal ang...

Surgical Management of Spondylolisthesis by Pedicular Screw Rod System and Postero-Lateral Fusion

Introduction: Incidence of spondylolisthesis in general population is 5% 7%. No matter what the etiology is, patients usually have significant functional disability. Few studies have investigated the long term effect of posterolateral fusion on functional outcome. Objectives: To study the efficacy of posterolateral fusion in spondylolisthesis especially in terms of functional outcome. Methodolo...
