Congenital hypoplasia of the arch of the atlas with abnormal segmentation of the cervical spine

Archives of Orthopaedic and Trauma Surgery, 1994
We describe a 53-year-old Japanese woman with absence of the posterior arch of the atlas. Computed tomography revealed that the residual posterior fragment which was displaced to the right side does not correspond to a rare ossification center in the midline and that there was no clear mass of the posterior arch except for a small fragment.

Cervical Myelopathy Accompanied With Hypoplasia of the Posterior Arch of the Atlas

Journal of Spinal Disorders & Techniques, 2009
Case reports of 2 patients having cervical myelopathy accompanied with idiopathic hypoplasia of the posterior arch of the atlas.A standard for the sagittal inside diameter (SID) of the vertebral foramen of the atlas was determined for use in the diagnosis of hypoplasia.

Spontaneous Fracture of Atlas of Cervical Spine Affected by Rheumatoid Arthritis

Scandinavian Journal of Rheumatology, 1985
A case of spontaneous fracture of the atlas in a 67-year-old woman who had suffered from rheumatoid arthritis for more than 20 years is described. This fracture is unique and can present diagnostic problems. Lying in the coronar plane makes the atlas difficult to visualize radiographically.

Why Atlas, why not Heracles: Reflections on the rheumatoid cervical spine

Seminars in Arthritis and Rheumatism, 2005
Rheumatoid involvement of the 24 joints of the cervical spine leads to prominent changes in the occipito-atlanto-axial area. Eight different subtypes of such changes are recognized, depicted, and defined. The frequencies of these 8 subtypes in rheumatoid arthritis and other arthritides are tabulated.

ATLAS-AXIS DISLOCATION FOLLOWING CERVICAL INFECTION

JAMA: The Journal of the American Medical Association, 1942
Dislocation of the axis on the atlas is often traumatic (frequently with fracture of the odontoid process and resultant damage to the cord), but it may also occur as a sequel to cervical infections. This second cause brings the patient into the field of the otorhinolaryngologist, who deals with infections in this region and who must recognize the ...

Cervical Myelopathy Due to Exostosis of the Posterior Arch of the Atlas

2016
Hereditary multiple exostosis (HME) is also called diaphyseal aclasis, multiple echondromatosis, Ehrenfried disease, hereditary deforming chondrodysplasia, and osteogenic disease. First described by Boyer in 1814, this condition has higher tendency to invade the spine and lead to myelopathy more than solitary osteochondromas, which occur mostly in the ...
