Cephalocaudal Variations in the Horizontal and Vertical Diameters of the Pedicles of the Lumbar Spine in the Turkish Population. Journal of Musculoskeletal Research, 5(1), 61-64.

In this study, we tried to figure out the differences, if any, in the size of the pedicles in a sample of the Turkish population. Methods: The horizontal and vertical diameters of the pedicles of the lumbar vertebrae were measured from the standardized anteroposterior radiographs of the lumbar spine in 100 subjects, aged from 20 to 40 years. Results: The mean horizontal width of the pedicles in our sample of the Turkish population was smaller than the subjects in other studies. The vertical diameter did not differ widely. There was a cephalocaudal increase in the horizontal diameters in both sexes. The vertical diameters did not increase. Significant differences between the pedicle diameters of the males and the females were noted at L2, L3 and L4 levels. No significant age-related variations were observed. Conclusion: Awareness of the racial variations in the size of the pedicles is very important when using international transpedicular screw systems. Preoperative determination of especially the horizontal diameter of the pedicles to be used for screw implantation from standardized anteroposterior X-rays is the easiest way.en10.1016/S0218-9577(01)00041-6info:eu-repo/semantics/closedAccessLumbar spinePediclesSpinal instrumentationTranspedicular screwArticle516164Q4
