Abstract: Atlantoaxial dislocation is one of the most common diseases of upper cervical vertebrae, and screw rod internal fixation has become the most widely used technique for posterior approach of atlantoaxial vertebrae. In recent years, a large number of studies have optimized the posterior atlantoaxial screw rod system, which has increased the safety of screw placement, the stability of internal fixation system and the ability of reduction. Through a comprehensive review of the pertinent literature on the optimization of posterior atlantoaxial screw-rod internal fixation technique both domestically and internationally over recent years, this paper reviews the evolution, characteristics, and optimization strategies of various commonly employed atlantoaxial screw placement technique, with the aim of assisting clinical decision-making in the management of atlantoaxial dislocation.
