Atlantoaxial anterior transarticular screw fixation: a case series and reappraisal of the technique

摘要

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 years ago, the published literature still lacks a comprehensive analysis of the procedure and a real case series.
