Abstract: (25 Views)
Background and Aim: The stability of the cervical spine is essential for treating spinal pathologies, including trauma, malformations, and tumors. Surgical stabilization, especially in the subaxial cervical vertebrae, often needs the use of lateral mass screws, laminar screws, and transpedicular screw fixation (TPSF). Due to the complex anatomy of the cervical spine and its variations among different ethnicities, as well as the high risks of surgical complications, it is crucial to understand its morphometric characteristics for more effective and safer surgical interventions. This study evaluates the feasibility of placing transpedicular, translaminar, and lateral mass screws (LMS) in the subaxial cervical vertebrae in the Iranian population by analyzing morphometric data obtained from cervical computed tomography (CT) scans.
Methods and Materials/Patients: A cross-sectional study was conducted using cervical CT scan imaging of 100 patients from Rajayee Hospital in Qazvin City, Iran. Specific measurements of the pedicle, lamina, and lateral mass were recorded. Statistical analysis was performed using SPSS software, version 19, with a focus on descriptive statistics and tests for differences between genders.
Results: The study presents detailed morphometric measurements of the subaxial cervical vertebrae in the Iranian population, including data from various cervical levels. Particularly, parameters, such as pedicle transverse angle, translaminar thickness, height, sagittal diagonal, and various lateral mass measurements, were analyzed, showing notable differences at each cervical level.
Conclusion: Comparing the data from the present study to similar studies of different ethnicities provides valuable insights into the morphometry of the subaxial cervical vertebrae in the Iranian population. The findings emphasize the importance of considering ethnic-specific anatomical variations in surgical planning, eventually leading to safer and less complicated surgical outcomes in spine surgeries.
