Background: Atlantoaxial Dislocation (AAD) is a complex disorder of craniovertebral junction (CVJ). Many techniques are available to treat AAD but there are some specific conditions where some techniques have advantage over the other. Technical Advantage:

Different Techniques of Atlantoaxial Posterior Screw Fixation with a Special Attention to High Riding Vertebral Artery [PDF]
Background: Posterior atlantoaxial fixation (AAF) is a standard surgical procedure for atlantoaxial joint instability (AAI). C1 lateral mass-C2 pedicle screw fixation is the most common adopted technique with high fusion rate, High riding vertebral ...

Design and Characterization of Mg Alloy Pedicle Screws for Atlantoaxial Fixation
To investigate the feasibility of using absorbable Mg alloy pedicle screws for atlantoaxial dislocation fixation, four types of Mg alloy pedicle screws of different thread forms were designed, and simulation analysis of the pull-out force was performed ...

ABSTRACT The equine cervical intervertebral foramina (IVF) represent vital anatomical regions facilitating the passage of spinal nerves and associated vasculature. An in‐depth understanding of their anatomy is imperative for the safe implementation of diagnostic and surgical interventions. Despite their clinical significance, anatomical descriptions of

Atlantoaxial anterior transarticular screw fixation. a case series and reappraisal of the technique
BACKGROUND CONTEXT: Atlantoaxial instability is commonly treated with C1-C2 fixation performed via posterior approaches. Although anterior transarticular screw (ATS) fixation, performed with a classic retropharyngeal approach, was described more than 10

Prediction Model for Etiologic Differentiation of Isolated Vestibular Syndrome in Emergency Settings
ABSTRACT Objective This study aimed to develop and validate a predictive model for differentiating central from peripheral etiologies in patients with isolated vestibular syndrome (VS). Methods In this multicenter retrospective cohort study, 506 patients with isolated VS from five hospitals were divided into derivation (n = 301) and validation (n = 205)

Atlantoaxial Rotatory Fixation in Adults Patient
Atlantoaxial rotatory fixation (AARF) in adult is a rare disorder that occurs followed by a trauma. The patients were presented with painful torticollis and a typical 'cock robin' position of the head. The clinical diagnosis is generally difficult and often made in the late stage. In some cases, an irreducible or chronic fixation develops.

Atlantoaxial instability treated with transarticular screw fixation [PDF]
We treated 11 patients with atlantoaxial instability using transarticular posterior screw fixation and lateral bone grafting. A posterior bone graft was added in eight patients. The results showed good reduction and a stable fixation. After 6 months ten patients had regained almost 70% of rotation and did not notice any significant limitation.
