This systematic review and meta-analysis examined cervical pedicle dimensions and insertion angles across diverse populations, analyzing data from 4014 patients across 18 countries. Significant differences in pedicle width (PW) were found, with East Asian populations showing the largest dimensions and South Asian populations the smallest. Notably, PW was greater in men than women at all levels.
Key findings
- Significant differences in pedicle width (PW) were observed at C3, C5, C6, and C7 vertebral levels across geographic groups.
- East Asian populations had the largest mean pedicle dimensions, while South Asian populations had the smallest.
- PW was consistently greater in men than women at all cervical levels.
- The sharpest pedicle transverse angle (PTA) was recorded in the East Asia subgroup at C7.
Why it matters
Understanding anatomical variations in cervical pedicle dimensions is crucial for optimizing surgical planning and improving outcomes in procedures involving cervical pedicle screws. This knowledge can help tailor approaches to individual patient anatomy based on geographic and demographic factors.
