2020-07-04 · All subjects had undergone C1-C2 reduction, fusion, and stabilization for atlanto-axial instability between 2017 and 2018 at a single institution by the authors (FCH, RR). The subjects were taken consecutively, with the exception that three patients (who did not respond to the lengthy questionnaires) were replaced with three subjects next on the list. Patients with os odontoideum, particularly with neurological symptoms and/or signs, and C1--C2 instability may be managed with posterior C1--C2 internal fixation and fusion.

C1 c2 instability

To perform this test, maximally flex the cervical spine followed by maximal rotation either left or right. Flexion is thought to lock out all vertebrae below allowing for rotation at C1-C2 only. Likewise, at the C1-C2 joint, instability in the form of AAI can cause an excessive uncovering of the joint facets. Facets are the surfaces of the vertebrae that articulate with next vertebra. An uncovering of the facets that exceeds 20% is considered pathological. 2020-05-13 · Atlantoaxial instability (AAI) is characterized by excessive movement at the junction between the atlas (C1) and axis (C2) as a result of either a bony or ligamentous abnormality. Neurologic 2017-11-25 · The implicated structures are generally centered around C1, C2, and C3 spinal levels.

Epidemiology: Anatomy. 50% rotation of the cervical spine occurs at C1-C2.(Bogduk Whiplash injuries frequently cause injury to the Alar and Transverse ligaments of C1 and C2. In turn, this causes LATERAL instability of C1 on C2, whereby, C1 can slide, on average, nearly five millimeters (a quarter of an inch), and up to 9 millimeters (a half an inch) sideways on C2. A retrospective review of 17 immature patients who underwent posterior spinal fusion of C1-C2 or C1-C3 was performed to establish the efficacy of the procedure, to determine the incidence of complications, and to identify those at high risk for complications. All had radiographic C1-C2 instability or dislocation. Eight patients with C1-C2 instability who underwent the posterior C1-C2 fusion using C1 lateral mass screw and C2 pedicle screw were identified and evaluated.
