Morphometric analysis by computed tomography of the entry point and trajectory for safe screw fixation surgery of the C2 pedicle in the Turkish population according to age and sex.
Article in Surgical and radiologic anatomy : SRA, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeThis study was conducted to evaluate the morphometric of the C2 vertebra in relation to screw fixation surgery and to establish standards for safe entry points and trajectories for pedicle screws.
methodsComputed tomography images of 323 individuals, comprising 163 females and 160 males aged 20-59 years, were used in the study. In the retrospective study, pedicle length (PL), pedicle thickness (PT), pedicle height (PH), pedicle angle (PA), pedicle-lamina angle (PLA), sagittal angle (SA), and ideal entry length (EL) parameters were evaluated on the right (R) and left (L) sides. The measured parameters were analysed in a total of 4 groups divided into age deciles.
resultsAs a result of our study, it was found that PL, PH, and EL parameters were higher in males compared to females on both sides (p < 0.05). It was found that RPL and RPA parameters were smaller than LPL and LPA, respectively, while the RPLA parameter was larger than the LPLA parameter (p < 0.05). In males, RPA, RSA, and LSA parameters were higher in group 1 than in group 4 (p < 0.05). In females, RPH and LPH parameters were found to be the largest in group 1 (p < 0.05).
conclusionIt has been observed that C2 morphometry is greater in male and decreases with age. These findings highlight the need for individual assessment in surgical planning and the importance of taking age and sex into account for clinical safety in interventional procedures such as screw placement.
