Concerned by his inability to rotate his neck, the clinician suggested CT of the upper cervical spine, which demonstrated rotary subluxation of the atlantoaxial junction. The patient was taken to the ...

Atlantoaxial instability (AAI) is a condition primarily affecting small breed dogs, particularly those with congenital predispositions. It involves instability at the atlantoaxial joint ...

Objectives: To examine whether functional radiography and functional magnetic resonance imaging (MRI) are equally efficient in detecting the extent of unstable anterior atlantoaxial subluxation (aAAS) ...

Spinal CT in the neutral position confirmed a C1/C2 rotary subluxation which reduced ... The occipital pain remains absent and he has achieved a solid fusion. Rotary atlantoaxial subluxation can be ...

Meningitis was considered. Lumbar puncture was negative for infection. A CT scan of the brain was performed, which showed no evidence of intracranial sepsis but images through the skull base suggested ...

Objectives: This study aimed to evaluate the necessity for further radiological investigation in patients with suspected traumatic rotatory subluxation of ... assessment of patients with atlanto-axial ...
