C1: Imax = 900 A. C2: Imax = 700 A. C3: Imax Such resonance and instability effects occur on frequencies higher than the line frequency.

C2 ─ retropharyngeal space should be < 7 mm ; C3 and C4 ─ retropharyngeal space should be < 5 mm, or Less than half the AP diameter of C3 or C4 ; C6 ─ retrotracheal space should be < 22 mm in adults and < 14 mm in children (under15 years) Treatment. These injuries are usually treated with some form of surgical fusion of C1 and C2

NECK PAIN. EDNF 2012 Conference August 2012 All rights reserved. 3. 2017-04-26 · Atlantoaxial Instability. We can consider that there is atlantoaxial instability or atlantoaxial subluxation (AA subluxation) in cases where there is principally incompetence of the ligamentous elements of the atlantoaxial (C1-C2) joint, which allow a significant increase in the mobility of this area thus considered pathological mobility.

Atlantoaxial Instability Treatment. Our surgeons provide a full range of treatments including non-surgical options as well as surgical repair. Often times if surgery is required, the bones between C1 and C2 are fused together, requiring less than 48 hours of an in-hospital stay.

It’s a hinge that helps your C1 pivot and allows you to turn your head left and right. Eighty-eight percent of RA patients have involvement of the C1-C2 junction. 15 As many as half of patients with RA develop symptomatic atlantoaxial subluxation, 56% of whom have myelopathy. 16 Postmortem examinations have indicated C1-C2 instability as the cause of death in as many as 10% of patients. 17 Classic radiographic findings include the staircase phenomenon, which is due to multiple The C1–C2 complex is stabilized by three major stabilizers, the odontoid process, the cruciate ligament, and the post-primary ligamentous apparatus (alar and joint capsular ligaments)7.

d an adult female patient with symptomatic atlantoaxial instability due to rheumatoid arthritis that was successfully treated with a bilateral C1–C2 transarticular screw fixation using a customized guiding block. We preoperatively determined the trajectories for bilateral C1–C2 transarticular screws on a 3-dimensional reconstruction model from the computed tomography (CT) and self
