Morphometric and functional study of the canine atlantoaxial joint

Research in Veterinary Science, 2020
The atlantoaxial joint can be affected by instability, in most cases a congenital pathology in young small breed dogs. Causes of atlantoaxial instability (AAI) are variable but are usually attributed to a lack of ligamentous support. The purpose of the present study was to specify the role of the ligamentous structures in the stabilisation of the ...

Atlantoaxial Joint Pain

2019
The atlantoaxial joint (AAJ) is crucial for axial rotation of the head. It is susceptible to pathology from both inflammation and trauma, and is commonly implicated in cervicogenic headache. This chapter reviews anatomy of the AAJ as well as evaluation and treatment of AAJ pathology.

Morphology and morphometry of lateral atlantoaxial joint meniscoids

Anatomical Science International, 2015
The lateral atlantoaxial joints contain folds of synovium termed meniscoids that may potentially contribute to cervical spine pain; however, the anatomy of these structures has not been comprehensively investigated. The purpose of this study was to explore the morphology and morphometry of lateral atlantoaxial joint meniscoids.

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).

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

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.
