Lower cervical spine stabilization necessitates precise knowledge of different osseous morphometric measures of the cervical vertebrae for accurate and safe application of fixa­tion devices. Human cadaveric stud­ies revealed significant variability worldwide raising the issue of possi­ble differences among races. This study was conducted on 28 osseous cadaveric models to obtain morpho­metric measurements among Egyp­tians. For posterior measures, 1.6 mm Kirschner wires were inserted in the cervical pedicles and lateral masses bilaterally to assess different linear and angular measurements. Linear measurements of the vertebral body were also assessed and pre­sented. All results were correlated with their surgical importance for both posterior and anterior lower cervical spine surgery. The results of this study revealed morphometric differ­ences between Egyptians and other races. Although most of these differ­ences are not statistically significant, yet it raises the necessity of extreme accuracy that should be considered in insertion of posterior cervical pedicle and lateral mass screws concerning, the point of insertion, length, diame­ter, sagittal and transverse angles and offsets. For anterior surgery, the transverse, sagittal and vertical meas­urements of the vertebral body should be precisely assessed for safe
