Traumatic posterior atlantoaxial dislocation based on imaging of the anterior arch-odontoid process-transverse ligament complex: a retrospective cohort study.

Journal of Neurosurgery : Spine
OBJECTIVE Traumatic posterior atlantoaxial dislocation (TPAD) is uncommon, and related research is very limited. By analyzing the imaging characteristics of the anterior arch-odontoid process-transverse ligament complex in patients, the authors classify ...

Osteoblastoma of the Odontoid Process

Pediatric Neurosurgery, 1994
A case of an osteoblastoma located in the odontoid process in a 7 year-old boy who presented with torticollis is reported. CT scan and MRI disclosed the lesion, but diagnosis was established by a CT-guided needle biopsy. Surgery through a transoral approach allowed total excision of the tumor.

Odontoid Process Fractures

2010
Fractures of the C2 odontoid process are the most frequent injuries of the upper cervical spine (UCS). The majority of them are located at the base of the process (Type II). Less frequently, the fracture line passes through the C2 body (Type III) and exceptionally it remains above the transverse ligament (Type I).

FRACTURE OF THE ODONTOID PROCESS

Australian and New Zealand Journal of Surgery, 1976
A review of 26 cases of odontoid fractures has been carried out. Late diagnosis and consequent delay in treatment were found to be important causes of non‐union. Myelopathy in odontoid fractures is of two types. One type is that present immediately after injury, while the other is delayed.

Internal Morphology of the Odontoid Process: Anatomic and Imaging Study with Application to C2 Fractures.

World Neurosurgery, 2019
OBJECTIVE Fracture of the odontoid process is a critical injury to diagnose and often treat. The aim of this anatomic study was to present a comprehensive understanding of this part of the C2 vertebra. METHODS We used 20 C2 vertebrae. Samples underwent

Gender and Age Estimation Using the Morphometric Analysis of Odontoid Process: Is There a Relationship With Dental Maturation?

The Journal of craniofacial surgery (Print), 2019
OBJECTIVE The purposes of this study were to show that differences in odontoid process related to age and gender using cone beam volumetric tomography, develop regression formulae based on metric data for gender and age estimation in a Turkish population

Transpalatal Excision of the Odontoid Process

Otolaryngology–Head and Neck Surgery, 1978
A patient with platybasia of the skull and temporomandibular joint ankylosis is presented. Relief of brain stem compression by the impingement of the odontoid through a soft, hypoplastic clivus was done by first doing a mandibular condylectomy to open the mouth. A transoral‐transpharyngeal route was then employed to excise the odontoid process.

RARE DEVELOPMENTAL ANOMALIES OF THE ODONTOID PROCESS OF THE AXIS

Oral surgery, oral medicine, oral pathology and oral radiology, 2019
Background Development of the odontoid process (dens) involves a primary ossification center and a secondary ossification center. The primary center gives rise to the body of the dens.

Congenital Anomalies of the Odontoid Process

Orthopedic Clinics of North America, 1978
Anomalous development of the odontoid is uncommon, and its clinical significance lies in its potential for producing serious neurologic sequelae due to atlantoaxial instability. Although there are several recognized variations (aplasia, hypoplasia, and os odontoideum), clinically they share the same signs and symptoms, and the treatment is identical ...
