Retropharyngeal Reduction Plate for Atlantoaxial Dislocation: A Cadaveric Test and Morphometric Trajectory Analysis

Orthopaedic Surgery, Volume 14, Issue 3, Page 522-529, March 2022., 2022
In this study, the cadaveric test showed that the retropharyngeal reduction plate was able to be placed on the atlantoaxial joint firmly, which is a safe treatment choice for some patients with irreducible atlantoaxial dislocation. Objective To evaluate the placement feasibility and safety of the newly designed retropharyngeal reduction plate by ...

Natural History, Neuroradiological Workup, and Management Options of Chronic Atlantoaxial Rotatory Fixation Caused by Drug‐Induced Cervical Dystonia

Case Reports in Orthopedics, Volume 2021, Issue 1, 2021., 2021
Atlantoaxial rotatory fixation (AARF) resulting from drug‐induced cervical dystonia (DICD) represents an extremely rare complication of antipsychotic treatment, requiring a comprehensive assessment of pharmacologic therapy and timely radiologic workup. We report a chronic case of Fielding type I, Pang type I AARF secondary to schizophrenia treatment in

Kinematic MRI Analysis of Reducible Atlantoaxial Dislocation for Decompression

BioMed Research International, Volume 2020, Issue 1, 2020., 2020
Background. Many doctors ignored the possibility that there is still a spinal cord compression (SCC) need for decompression after atlantoaxial reduction. Reduction can be achieved on kinematic magnetic resonance imaging (MRI); thus, we want to analyze the role of kinematic MRI in reducible atlantoaxial dislocation and make a preoperative decision ...

Nasoseptal flap revision in endoscopic endonasal odontoidectomy for acute atlantoaxial osteomyelitis with atlantoaxial subluxation

Formosan Journal of Surgery, 2021
Vertebral osteomyelitis compromises approximately 1%–7% of all cases of osteomyelitis, whereas the cervical region is affected in 3%–10% of all cases. Not surprisingly, osteomyelitis at the craniocervical junction is a rare occurrence that poses certain ...

Fusion Surgery Required for Recurrent Pediatric Atlantoaxial Rotatory Fixation after Failure of Temporary Fixation with Instrumentation

Case Reports in Orthopedics, Volume 2017, Issue 1, 2017., 2017
In cases of chronic irreducible and recurrent unstable atlantoaxial rotatory fixation (AARF), closed reduction and its maintenance are often unsuccessful, requiring surgical treatment. The purpose of the present report is to describe a rare case of pediatric AARF that required multiple treatments.
