Feasibility and Safety of the C1 "Zero Angle" Screw: A Novel "In-Out-In" Technique for Atlantoaxial Dislocation. [PDF]

Orthop Surg
The C1ZAS with “in–out–in” technique is presented as an alternative to C1 PS in cases of AAD with a trajectory parallel to the sagittal plane. This method involves penetrating the recess of the atlas to achieve tricortical or quadricortical purchase for rigid fixation while minimizing the risk of injury to the V3 segment of the VA.

Concomitant atlantoaxial and atlanto-occipital rotatory dislocation in children: Radiological features, diagnostic pitfalls, and long-term outcome

Journal of Orthopaedic Surgery, 2021
While the pathological manifestation of atlantoaxial rotatory dislocation has been well described in the medical literature, the combined dislocation of the atlantoaxial and atlanto-occipital joints, or OAARD – short for occipital-atlantoaxial rotatory ...

Novel MRI Signs in Atlantodental Space Predict Reduction Degree of Atlantoaxial Dislocation. [PDF]

Orthop Surg
We summarized cases of AAD, classified based on the atlantodental space using magnetic resonance imaging (MRI). and preliminarily explored its impact on the degree of reduction. We found patients with high signal intensity were more likely to achieve satisfactory reduction after direct posterior surgery.
