Lateral Atlantoaxial Joint Arthrography in Atlantoaxial Rotatory Fixation

Journal of Spinal Disorders & Techniques, 2003
There has been much debate about the pathogenesis of atlantoaxial rotatory fixation. Intraarticular abnormality has not been well documented thus far. This is the first case of chronic atlantoaxial rotatory fixation in which atlantoaxial joints were examined by consecutive arthrography.

Rotary Fixation of the Atlantoaxial Joint: Rotational Atlantoaxial Subluxation

Radiology, 1968
Although the anatomy and movements of the atlantoaxial joint are now well documented, much remains unknown regarding pathological conditions of this area. Infections of varying etiologies, as well as trauma, are well-known factors in the production of a forward atlantoaxial subluxation (26, 29, 37, 38).

Classification of the facets of lateral atlantoaxial joints in patients with congenital atlantoaxial dislocation

European Spine Journal, 2020
To investigate the morphological characteristics and para-positions of the facets of lateral atlantoaxial joints (FLAJs) in patients with congenital atlantoaxial dislocation (CAAD) and to propose a classification system for the FLAJs.A total of 93 cases of CAAD were included in this retrospective study.

Spontaneous pneumarthrosis of the atlantoaxial joint

Journal of Neurosurgery: Spine, 2012
The authors describe the case of a 29-year-old man presenting with left retrooccipital and cervical pain associated with left ear fullness and rhythmic tinnitus. Head rotation movements on the right side and the Valsalva maneuver increased symptoms. A CT scan identified hyperpneumatization of the left temporal bone extending to the occipital bone as ...

Septic Arthritis of the Atlantoaxial Joint

Journal of Spinal Disorders & Techniques, 2006
Bacterial epidural abscess formation of cervical spine was rarely seen and all these cases were associated with osteomyelitis of the odontoid process. To the author's knowledge, only 1 case of septic arthritis of the C1-C2 lateral facet joint has been reported in the English literature.

A review of canine atlantoaxial joint subluxation

Veterinary and Comparative Orthopaedics and Traumatology, 2015
SummaryAtlantoaxial subluxation was first reported in dogs nearly fifty years ago. Since that time a better understanding of the aetiologies pre-disposing to joint laxity and instability has been achieved. Surgeons however are still trying to address the problems associated with stabilizing this joint which by nature is often required in small juvenile

Atlantoaxial Joint: Atlantoaxial Joint Injection and Radiofrequency Ablation

2014
Cervicogenic headache is referred pain from cervical structures innervated by the upper three cervical spinal nerves. The lateral atlantoaxial joint is innervated by the C2 ventral ramus. It is a fairly common cause of cervicogenic headache as it may account for up to 16 % of patients with occipital headache.

Rotational obstruction of the vertebral artery at the atlantoaxial joint

Neuroradiology, 1975
Two patients with vertebrobasilar ischemia are described in whom angiography demonstrated obstruction of one vertebral artery at the C1-2 level on rotation of the head. The possible anatomical explanation and physiological significance of this finding are discussed.

[Dislocation of the atlantoaxial joint].

Der Unfallchirurg, 2015
Injuries of the cervical spine in adolescents only occur in 0.2 % of cases. Due to the mismatch of size of the head in comparison to the relatively weakly developed neck muscles at this age, the cranial section is more vulnerable to injuries of any kind compared to the lower sections of the cervical spine.

Calcifying pseudoneoplasm of the atlantoaxial joint in a child.

Journal of neurosurgery. Spine, 2013
Calcifying pseudoneoplasm of the spine is a rare nonneoplastic lesion of unknown origin described in adolescents and adults. Its clinical manifestations include axial pain, myelopathy, or radiculopathy. Surgery is the preferred method of treatment. The authors report the occurrence of calcifying pseudoneoplasm at the C1-2 cervical segment in a 22-month-
