1. Retro-odontoid pseudotumor: a poorly recognized alteration of the craniocervical junction
RESUMO INTRODUÇÃO O pseudotumor retro-odontoide (PRO) é uma patologia rara que acomete a articulação atlantoaxial e, em geral, está associada a alterações biomecânicas locais que podem ou não causar instabilidade. METODOLOGIA Estudo descritivo da literatura disponível nas bases de dados Medline/PubMed, Lilacs e Scopus. A pesquisa foi realizada

2. Fractures of the cervical spine
OBJECTIVES: The aim of this study was to review the literature on cervical spine fractures. METHODS: The literature on the diagnosis, classification, and treatment of lower and upper cervical fractures and dislocations was reviewed. RESULTS: Fractures of the cervical spine may be present in polytraumatized patients and should be suspected in patients co

3. Atlantoaxial instability secondary to agenesis of the odontoid process of the axis without rupture of the dorsal atlantoaxial ligament in a dog / Instabilidade atlantoaxial secundária à agenesia do processo odontóide do áxis sem ruptura do ligamento atlantoaxial dorsal em cão
A instabilidade atlantoaxial é uma condição congênita ou traumática que causa dor cervical e vários graus de disfunção neurológica. Um caso de instabilidade atlantoaxial secundário a agenesia do processo odontóide do áxis sem evidência de ruptura do ligamento atlantoaxial dorsal em um cão tratado cirurgicamente com sucesso é relatado. Um cão

4. Morfometria do processo odontÃide em espÃcimens obtidos na cidade do Recife
The odontoid fractures increase its frequency from adult age; being the most frequent fracture of the backbone beyond 80 years of age. Its modern treatment requires detailed knowledge of the spine anatomy for getting an adequate fixation, and the necessary lesser post-operative immobilization; reducing morbidity and mortality. The purpose of the study was to

6. Somatosensory and brainstem auditory evoked potential in congenital craniovertebral anomaly; effect of surgical management.
Clinical features and evoked potential recordings were analysed in 32 patients with congenital atlantoaxial dislocation before and after surgery. Seven patients (group 1) had atlantoaxial dislocation, while 22 patients had associated basilar invagination (group 2). In both groups, pyramidal tract signs, posterior column signs, wasting of the upper limbs, and

7. Spectacular morphological novelty in a miniature cyprinid fish, Danionella dracula n. sp.
Danionella dracula is a new species of sexually dimorphic, miniature and highly developmentally truncated cyprinid fish. Compared with its close relative, the zebrafish Danio rerio, it lacks 44 bones or parts thereof and represents one of the most developmentally truncated vertebrates. Absence of the majority of bones appears to be due to developmental trunc

8. Spontaneous atlantoaxial subluxation: an unusual presenting manifestation of Reiter's syndrome.
A male Sikh presented with spontaneous neck pain. Plain cervical radiography showed gross atlantoaxial subluxation (AAS). Computed tomography showed soft tissue anterior to a subluxed odontoid peg. A diagnosis of atlantoaxial tuberculosis was considered. Confirmation of this would have required a trans-oral anterior cervical biopsy. Despite the paucity of ot

9. Rheumatoid C1—C2 dislocation: pathogenesis and treatment reconsidered
The commonly accepted mechanism of rheumatoid C1—C2 dislocation is the incompetence of the transverse ligament of C1 vertebra. The presence of rheumatoid granulation tissue between the anterior arch of C1 vertebra and the odontoid process is an important factor. This might explain why the dislocation becomes irreducible when the disease progresses. In a 55

10. Surgical treatment of cervical cord compression in rheumatoid arthritis.
Cervical myelopathy is a rare but potentially dangerous complication of rheumatoid arthritis and presents considerable therapeutic problems. A conservative approach carries high mortality and surgical intervention is not without serious risks. Reduction of subluxation and posterior fusion is widely practised but may require prolonged bed rest and continuous

11. Are computed tomography scans adequate in assessing cervical spine pain following blunt trauma?
Good quality three‐view radiographs (anteroposterior, lateral, and open‐mouth/odontoid) of the cervical spine exclude most unstable injuries, with sensitivity as high as 92% in adults and 94% in children. The diagnostic performance of helical computed tomography (CT) scanners may be even greater, with reported sensitivity as high as 99% and specificity 9

12. Calcification of the transverse ligament of the atlas in chondrocalcinosis: computed tomography study.
OBJECTIVE: To seek an association between articular chondrocalcinosis (AC) and calcification of the transverse ligament of the atlas (TLA), and to evaluate the frequency and the main computed tomography appearances of such calcification. METHODS: Axial computed tomography slices of the cervico-occipital hinge were performed routinely in 21 patients with AC (
