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...

OBJECTIVE To investigate the feasibility of C1 lateral mass screw and C2 pedicle screw with polyaxial screw and rod system supplemented with miniplate for interlaminar fusion to treat various atlantoaxial instabilities. METHODS After posterior atlantoaxial fixation with lateral mass screw in the atlas and pedicle screw in the axis, we used 2 miniplates to fixate interlaminar iliac bone graft ...

BACKGROUND Atlantoaxial rotatory fixation is a condition in which the first and second vertebrae of the cervical spine become interlocked in a rotated position. This condition can result in serious consequences and thus have a significant impact on patients, especially when diagnosis and treatment are delayed. Some cases of atlantoaxial rotatory fixation have been described in association with ...

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...

Atlanto-axial rotatory subluxation is a rare condition in childhood. A sudden onset of pain and limitation in neck movements are the most common presenting features. Usually, a previous trauma history exists. This study presents a case of an 18-month-old male with neck stiffness and pain in neck through palpation without trauma in his history but with rotatory subluxation of 30° in atlanto-axia...

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...

Abstract Background To introduce a novel transoral instrumentation in the treatment of unstable fractures atlas. Methods From January 2008 to May 2018, 22 patients with C1 who received Jefferson-fracture reduction plate (JeRP) via approach were retrospectively analyzed. The case history and radiographs before after surgery noted. type fracture, position internal fixation assessed through preope...

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...
