Brief Summary:
The aim of study to analyze morphometry of sub axial cervical spine pedicle in an Egyptian population based on computed tomography CT and thus asses the safety and feasibility of cervical pedicle screw in the sub axial cervical spine
Detailed Description:
Cervical pedicle screw CPS fixation is found to be superior compared with lateral mass screws because it provides more axial bending and torsional stability and has a low risk of loosening with cyclical loading Despite biomechanical superiority CPS fixation is not universally accepted among surgeon s because their accuracy and safety remain technically challenging because of the close proximity of vital structures as spinal cord and vertebral artery and inherent variability in pedicle at each level In addition limited space is available for screw placement because of complex of cervical spine vertebrae Therefore the risk of complication due to screw violation of the adjacent vascular and neural structures is expected to be high when performing the operation without a clear understanding of morphometric characteristics of the pedicle Morphometry of the cervical pedicles was studied before using cadavers but comparative computed tomography CT data from the age matched population shown significant differences Recent advances in CT have made anatomic measurements more accurate The present study was undertaken to determine the 3-dimensional pedicle geometry by calculating variables like pedicle length PL Pedicle height PH Pedicle width PW Pedicle axis length PAL Pedicle transverse angulation PTA Pedicle sagittal angulation PSA Superior pedicle distance SPD and lateral pedicle distance LPD Fortunately computed tomography CT scanning become a routine preoperative examination in spinal surgery patients
