Study design Systematic review and meta-analysis. Aim The purpose of this study was to
compare the safety and accuracy of the C2 pedicle versus C2 pars screws placement and …

The atlantoaxial joint C2 (axis) with the anterior arch of C1 (atlas) allows 50% of cervical
lateral rotation. It is responsible for precise and important movements that allow us to …

Objective Ponticulus posticus is an anomaly of the atlas. Odontoid fracture type 2 fracture
occurs by hyperflexion, hyperextension, lateral flexion, and a combination of these …

Background Atlantoaxial instability is mainly caused by trauma. C2 nerve is usually needed
to be sacrificed for adequate exposure of the lateral mass and screw insertion. Objectives …

Objective Both transarticular screw fixation (TAS) and segmental screw-rod fixation (SF)
have been widely performed for C1-2 fusion; however, just only small clinical studies and a …

AIM To investigate the changes in relevant anatomical parameters of posterolateral
protrusion of the vertebral artery (VA) between head–neck rotational and neutral positions …

Background: Few studies have reported on the long-term outcomes of Goel and Harms C1-
C2 fusions in the Asian population. Methods: This was a retrospective analysis of 53 patients …

Objective: The aim of this study is to present the clinical experience and results in the
application of atlantoaxial stabilization performed with Harms technique to contribute to the …

Background: The presence of the C2 root ganglion with its surrounding venous plexus at the
region of C1-2 joint makes surgical dissection technically demanding. Although it may result …

Objective The aim was to evaluate the posterior atlantoaxial fixation using C1 lateral mass
and C2 pedicle by a polyaxial screw in atlantoaxial instability correction. Background The …
