Bilateral C1-C2 claw for atlantoaxial instability.
OBJECTIVE 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. METHODS AND MATERIAL Seven patients with atlantoaxial instability were operated by using C1 and C2 hooks, rods and transverse connector at Neurosurgery Clinic of Istanbul University Cerr...
متن کاملImproving C1-C2 Complex Fusion Rates: An Alternate Approach
The surgical repair of atlantoaxial instabilities (AAI) presents complex and unique challenges, originating from abnormalities and/or trauma within the junction regions of the C1-C2 atlas-axis, to surgeons. When this region is destabilized, surgical fusion becomes of key importance in order to prevent spinal cord injury. Several techniques can be utilized to provide for the adequate fusion of t...
متن کاملχ_{c1} and χ_{c2} Resonance Parameters with the Decays χ_{c1,c2}→J/ψμ^{+}μ^{-}.
The decays χ_{c1}→J/ψμ^{+}μ^{-} and χ_{c2}→J/ψμ^{+}μ^{-} are observed and used to study the resonance parameters of the χ_{c1} and χ_{c2} mesons. The masses of these states are measured to be m(χ_{c1})=3510.71±0.04(stat)±0.09(syst) MeV and m(χ_{c2})=3556.10±0.06(stat)±0.11(syst) MeV, where the knowledge of the momentum scale for charged particles dominates the systematic uncertainty. The mome...
متن کاملPreoperative flexion-extension radiographs can't exclude c1/c2 reducibility in c1/c2 subluxation
Background: According to the findings of previous studies, treatment of C1/C2 subluxation especially in congenital anomaly depends on preoperative dynamic radiograph and site (anterior or posterior) of cord compression. Evolution of new technique for instrumentation intraoperative manipulation is more feasible. We present our experience of treating 5 cases “apparently” irreducible atlantoaxial ...
متن کاملC1-C2 fusion: postoperative C2 nerve impingement—is it a problem?
OBJECTIVE The purpose of this comparison case study is to show a potential complication associated with atlantoaxial fusion, and the preoperative evaluation that could help to avoid it. BACKGROUND DATA The use of lateral mass screw fixation in atlantoaxial fusion has provided surgeons the ability to create rigid fixation, with a high success rate of fusion. While the use of screws for fixat...
