Design of a Novel Artificial Atlanto‐Odontoid Joint and Its Anatomical and Radiological Studies Following Transoral Pharyngeal Approach Arthroplasty

Orthopaedic Surgery, Volume 17, Issue 9, Page 2670-2679, September 2025.
The implantation of the novel artificial atlanto‐odontoid joint (AAOJ) is both safe and convenient, and it preserves the normal range of rotational, flexion‐extension, and lateral bending motion between the atlas and axis. ABSTRACT Objective For atlantoaxial joint disorders, traditional surgical approaches often presented challenges such as significant
