Bilateral C1-C2 claw for atlantoaxial instability.

Turkish neurosurgery, 2009
Atlantoaxial stability can be achieved by laminar hook systems via posterior approach. This technique is much more safer than using screws. We presented our experience with the C1-C2 claw procedure.Seven patients with atlantoaxial instability were operated by using C1 and C2 hooks, rods and transverse connector at Neurosurgery Clinic of Istanbul ...

Role of Posterior Interfacetal Distraction and Grafting in Complex Atlantoaxial Dislocation

Egyptian Spine Journal, 2019
Background Data: Atlantoaxial fixation, unlike subaxial spine, is still challenging due to complex topographical anatomy. Nowadays, atlas lateral mass screws and transpedicular axis screws fixation is a well-accepted technique for the management of ...

Cervical Fusion as a Protective Response to Craniovertebral Junction Instability: A Novel Concept [PDF]

Neurospine, 2018
The author reviews the various types of cervical fusion that are associated with instability of the craniovertebral junction. Assimilation of the atlas, C2–3 fusion, the Klippel-Feil abnormality, and pancervical fusion are amongst the more common types ...

Surgical Therapy to Atlantoaxial Instability

, 2021
Atlantoaxial instability (AAI) is a term that is used to describe instability at the atlantoaxial joint of the cervical spine. This is often from alar ligament instability causing the dens of the axis to be prone to move posterior or sublux.
