Preoperative 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 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 کاملManagement of anteriorly located C1-C2 neurofibromata.
The authors discuss their recent experience with anteriorly located C1-C2 neurofibromata in five patients with cervical myelopathy and magnetic resonance scans consistent with intradural extramedullary masses in this region. Surgery was performed using a posterolateral approach with microscopic intradural exploration. Gross total intradural tumor removal was achieved in all cases. Improvement i...
متن کاملON SINGULARITIES OF MIP 3(c1, c2)
Let MIP 3(c1, c2) be the moduli space of stable rank-2 vector bundles on IP 3 with Chern classes c1, c2. We prove the following results. 1) Let 0 ≤ β < γ be two integers, (γ ≥ 2), such that 2γ− 3β > 0; then MIP 3(0, 2γ 2 − 3β) is singular (the case β = 0 was previously proved by M. Maggesi). 2) Let 0 ≤ β < γ be two odd integers (γ ≥ 5), such that 2γ − 3β + 1 > 0; then MIP 3(−1, 2(γ/2) 2 − 3(β/2...
متن کاملAccidental spinal cord injection of contrast material during cervical myelography with lateral C1-C2 puncture.
A 64-year-old woman was admitted to our hospital with slowly increasing paresis of the extremities. Because an intramedullar tumor was suspected, cervical myelography with lateral puncture of C1-C2 was performed. A 22-gauge needle was used, and normal return of clear, colorless spinal fluid was seen. During the uneventful injection of Omnipaque (iohexol, 240 mg I/ml), a longitudinal stripe of c...
