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. She underwent C1-C2 screw fixation where a screw was placed through the C1-C2 joint to fuse it and to reduce her instability. Regrettably, on one side that screw was placed too deep and she woke up from surgery with new pain right at the base of the skull on that side. This video is an animated demonstration of C1-C2 instability and is not meant to be an exact anatomical model.

Postoperative Apr 29, 1999 Levy ML, McComb JG: C1-C2 fusion in children with atlantoaxial instability and spinal cord compression: Technical note. Neurosurgery 1996 Atlantoaxial instability (AAI) is characterized by hypermobility of. C1-C2 joint due to laxity of alar ligament, being common in Down syndrome patients. The aim of However, C1 lateral mass – C2 pedicle screw fixation is gaining popularity in handling the atlantoaxial instability.

Figure 3: Axial CT scan through C1-C2 showing loss of facet overlap on full neck rotation, consistent with AAI. Figure 4: AP open-mouth radiograph of the C1-C2 levels showing pathological loss of overlap. Treatment For milder form of instability, the patient should be considered for Se hela listan på mskneurology.com 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 symptoms can occur when the spinal cord or adjacent nerve roots are involved. AAI can occur as a result of abnormalities or trauma associated with c1-c2… The other method to assess C1-C2, which I learned in PT school at St. Louis University, is the flexion- rotation test. To perform this test, maximally flex the cervical spine followed by maximal rotation either left or right.

Dr Sonam Vadera and Rishi Agrawal et al. Atlanto-axial subluxation is a disorder of C1-C2 causing impairment in rotation of the neck. The anterior facet of C1 is fixed on the facet of C2. It may be associated with dislocation of the lateral mass of C1 on C2. On this page: Why Inherent C1-C2 Instability Can Wreck Havoc with Patients. Given that the C1-C2 joint is inherently unstable, if it doesn’t have ligaments to muscles to hold in in place, it tends to move out of place.
