Atlantoaxial Subluxation due to an Os Odontoideum in an Achondroplastic Adult: Report of a Case and Review of the Literature

Case Reports in Orthopedics, Volume 2015, Issue 1, 2015., 2015
The authors report the first example of an adult achondroplastic dwarf with progressive quadriparesis secondary to atlantoaxial subluxation as a consequence of an os odontoideum. Actually, craniocervical region is a frequent site of compression and myelopathy in achondroplasia particularly in children as a result of small foramen magnum and ...

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
