STUDY DESIGN Retrospective study. OBJECTIVE The aim of the study was to introduce the surgical techniques and evaluate the clinical outcomes of transoral atlantoaxial reduction plate (TARP) for the treatment of atlantoaxial dislocation. SUMMARY OF BACKGROUND DATA Researchers have reported on transoral plate internal fixation for the treatment of irreducible atlantoaxial dislocation (IAAD) w...

Grisel's syndrome is a non-traumatic subluxation of the atlantoaxial joints, which is caused by an inflammatory process in the upper neck. It is rare to find literary reports of Grisel's syndrome with an evident pathogen in a lesion. For the first time in Korea, we report a 36-year-old female with Grisel's syndrome having an atlantoaxial subluxation, which was caused by a retropharyngeal absces...

We report a case of 64-year-old Tunisian woman with a 12-year history of rheumatoid arthritis, who presented with a 3-month history of increasing inflammatory neck pain. Neurological examination noted a quadripyramidal syndrome without any neurological deficit. Radiographs of her neck showed ananterior atlantoaxial subluxation (A). MRI revealed a pannus around the atlanto axial joint. It also s...

We evaluated the use of surgical stabilisation for atlantoaxial subluxation after a follow-up of 24 years in 50 rheumatoid patients who had some degree of pain but no major neurological deficit. The mortality of patients treated by atlantoaxial fusion was significantly lower than for those who received conservative treatment. The deaths resulted from infection or comorbid conditions. The signif...

Objectives: The role of intra-articular meniscoids in spinal pathology is unclear, and their anatomy not well understood. Spinal meniscoids have been identified in research using dissection and imaging. No previous studies have identified these structures using E12 sheet plastination; such methods of visualising meniscoids are likely of value in research and education. Our aim was to examine th...

Atlantoaxial disorders are often correlated with hypertension in practice. In order to study the relationship between atlantoaxial disorder and hypertension, we attempted to construct an animal model. In this work, we presented an animal model where their atlantoaxial joints were misaligned. We investigated the changes of blood pressure before and after treatments of the modeled rats. We had th...

Atlantoaxial facet joints have been proposed as the center of mobility and also center for instability of the atlantoaxial region. Because of the high mobility of the atlantoaxial (C1-C2) motion segment, fusion rates at this level have been substantially lower than those at the subaxial spine. The success of craniovertebral junction surgery depends on adequate reduction, decompression of cranio...

Revision surgery for os odontoideum with irreducible atlantoaxial dislocation with a transoral approach is not commonly seen. Typically, management of this type of atlantoaxial dislocation is through posterior fixation and fusion or transoral decompression and posterior fusion. This report describes revision surgery in a patient with os odontoideum who was treated with a transoral approach. A 5...

INTRODUCTION Atlantoaxial rotatory subluxation is rarely caused by trauma in adults. Usually, the treatment of choice is traction using Halo/Gardner-Wells fixation devices for up to six weeks. CASE PRESENTATION We present the case of a 19-year-old Caucasian woman with traumatic atlantoaxial subluxation. Early reduction three hours after trauma and immobilization using only a soft collar were ...
