ATLANTO-AXIAL FRACTURE-DISLOCATIONS

, 1973
1. Ten consecutive cases of acute atlanto-axial fracture dislocation were treated by posterior C.1-C.2 fusion. 2. In eight cases there was significant redislocation warranting further therapy. 3.

DataSheet1_Biomechanical comparison of anterior axis-atlanto-occipital transarticular fixation and anterior atlantoaxial transarticular fixation after odontoidectomy: A finite element analysis.pdf

, 2023
Background: Anterior axis-atlanto-occipital transarticular fixation (AAOF) and anterior atlanto-axial transarticular fixation (AAF) are two common anterior screw fixation techniques after odontoidectomy, but the biomechanical discrepancies between them ...

Full Clinical Pathological and Bacteriological Investigation of a Giant Nasal Polyp Associated With the Developing Apex of the Permanent Fourth Premolar (Triadan 108) in a 3‐year‐old Connemara Filly: A Case Report

Veterinary Medicine and Science, Volume 12, Issue 1, January 2026.
A 3‐year‐old Connemara X filly presented with unilateral nasal discharge and facial swelling. Diagnostic imaging revealed a soft tissue mass with mineralisation and dental pathology (108). Histopathology confirmed a fibro‐inflammatory polyp. This case highlights a rare equine sino‐nasal polyp associated with endodontic disease, demonstrating a ...

Atlanto-axial rotatory subluxations in postmortem CT: radiologists be aware of a common pitfall

, 2013
The aim of the present study was to determine the frequency of atlanto-axial rotatory subluxations (AARS) in multi detector computed tomography (MDCT) performed on human corpses for forensic purposes and to investigate whether these are a physiological ...

Anterior Transoral Odontoid Reduction With Clivocervical Fusion in Revision Surgery for Craniovertebral Junction Anomalies: A Case Report and Technical Note

Orthopaedic Surgery, Volume 18, Issue 1, Page 194-201, January 2026.
For revision CVJAs with persistent ventral compression after failed posterior fixation, anterior transoral odontoid reduction combined with clivocervical fusion achieved direct decompression, restored clivo‐axial angle, resolved spinal cord compression, and provided stable fusion with significant neurological recovery, offering an effective salvage ...

Atlanto-axial rotatory fixation and fracture of the clavicle. An association and a classification

, 1990
Five children with atlanto-axial rotatory fixation (AARF) in association with fractures of the clavicle are described. It is postulated that the rotary fixation is a direct result of the trauma which produces the fracture.

Comparison of Two Posterior Minimally Invasive Approaches for Odontoid Fractures: Midline Nuchal Ligament Approach vs. Paramedian Muscle‐Splitting Approach

Orthopaedic Surgery, Volume 18, Issue 1, Page 74-83, January 2026.
The midline nuchal ligament approach yields clinical outcomes similar to those of the paramedian muscle‐splitting technique for odontoid fractures, while offering a more stable surgical procedure and reducing iatrogenic injury to the cervical posterior muscles and the greater occipital nerve.

Stamina of a non-gasketed flange joint under combined internal pressure and axial loading

, 2008
The performance of a bolted flange joint is characterized mainly by its 'strength' and 'sealing capability'. A number of numerical and experimental studies have been conducted to study these characteristics under internal pressure loading conditions ...

Morphometric Evaluation of the Craniovertebral Junction Using Computed Tomography: A Sex‐Based Analysis of 500 Adults

BioMed Research International, Volume 2026, Issue 1, 2026.
Background and Objective The anatomy of the craniovertebral junction (CVJ) varies considerably across populations, yet comprehensive Turkish‐specific morphometric data remain limited. We aim to establish normative CVJ measurements in Turkish males and females using computed tomography (CT). Study Design Retrospective morphological study.
