“…Previous reports on the use of cervical pedicle screws have focused on anatomical specialties of the cervical spine [6,9,14,17,18], biomechanical issues [6,10,15] and surgical techniques [8,11,12]. Few publications dealt with the complications attributed to this surgical technique [1,8].…”

“…The recent literature describes the use of transpedicular screws in all cervical segments [1][2][3]8]. Pedicle screws in the cervical spine have been shown to have significantly higher pullout strength and higher primary stability than lateral mass screws [10,15].…”

“…However, as Kamimura et al [13] quite rightly pointed out, the surgeon still needs to know the pedicle morphology to ensure that the computer guides the screws correctly. The overall consensus throughout these articles is that no matter what the technique, the surgeon needs to have a high level of three-dimensional anatomical knowledge, to ensure safe placement of cervical pedicle screws [15,37].…”

The ipsilateral lamina–pedicle angle: can it be used to guide pedicle screw placement in the sub-axial cervical spine?

et al. 2009

Pedicle screws in the sub-axial spine are infrequently used because of concerns over their safety and difficulty in placement, despite their superior pullout strength. In the sub-axial cervical vertebrae, we have observed that the lamina appears to project at right angles to the ipsilateral pedicle axis. The aim of this investigation was to confirm the lamina orientation as a reliable landmark for pedicle screw placement. 80 digital cervical spine CT were analysed. The angle formed by the ipsilateral outer lamina cortex to the pedicle axis was recorded. A total of 398 vertebrae were analysed from patients with a mean age of 39.5 years (range 18-78). Average axial lamina-pedicle angle ranged from 96.6°at C3 to 87.2°at C7 in males, and from 95.6°to 87.5°in females. The angle formed by the posterior cortex of the lamina and the ipsilateral pedicle shows a high level of consistency for subaxial cervical vertebrae ranging from 96°at C3 to 87°at C7. Although the angle is not exactly 90°at all levels as hypothesised, the orientation of the lamina, nevertheless, forms a useful reference plane for insertion of pedicle screws in the sub-axial cervical spine.
