Objective: To study effects of a combined regime of auricular-plaster and body acupuncture in treatment of cervical spondylosis of vertebral artery type and make a preliminary revelation of the mechanism.
Methods: Ninety-two patients were randomly divided into 2 groups, the treatment group (n = 56) received the combined regime of auricular-plaster and body acupuncture, and the control group (n = 36) received treatment with body acupuncture. Clinical symptoms and signs, therapeutic effect and some indexes about vertebrobasilar hema-kinetics and hema-rheology were investigated before and after treatment.
Results: The treatment group was better than the control group in the clinical overall effective rate (89.29%) and the clinically control rate (17. 85%), and in improving the following indexes, including dizziness and headache, the vertebrobasilar volume and rate of blood flow etab and IR (P < 0.05).
Conclusions: A combined regime of auricular-plaster and body acupuncture ameliorates not only main signs but also some indexes about vertebrobasilar hema-kinetics and hema-rheology. This treatment is an effective therapy for cervical spondylosis of vertebral artery type both in Malaysia and in China.

The evolution of instrumentation methods for C1-C2 fusion from the use of posterior wiring methods to transarticular screws and C1 lateral mass with C2 pedicle screw construct have improved fusion rates to almost 100%. However, the C1 lateral mass and C2 pedicle screw technique is technically demanding. This is a prospective review of a series of ten patients who was planned for C1-C2 fusion using C1 lateral mass and C2 pedicle screw technique between January 2007 and June 2009. The procedure was converted to occipital cervical fusion due to a fracture of a hypoplastic lateral mass-posterior arch complex in one patient and Gallie fusion due to a vertebral artery injury in another. Eight patients underwent the C1-C2 fusion using C1 lateral mass and C2 pedicle screw successfully without any complications. The union rate was 100% with an average union time of 5.3 months (range from 3 to 8 months). Postoperatively, the patients achieved an average of one Frankel grade neurological improvement. In conclusion, this technique provides an excellent union rate and good neurological recovery.

BACKGROUND: Various lateral mass screw fixation methods have been described in the literature with various levels of safety in relation to the anterior neurovascular structures. This study was designed to radiologically determine the minimum lateral angulations of the screw to avoid penetration of the vertebral artery canalusing three of the most common techniques: Roy-Camille, An, and Magerl.
MATERIALS AND METHODS: Sixty normal cervical CT scans were reviewed. A minimum lateral angulation of a 3.5 mm lateral mass screw which was required to avoid penetration of the vertebral artery canal at each level of vertebra were measured.
RESULTS: The mean lateral angulations of the lateral mass screws (with 95% confidence interval) to avoid vertebral artery canal penetration, in relation to the starting point at the midpoint (Roy-Camille), 1 mm medial (An), and 2 mm medial (Magerl) to the midpoint of lateral mass were 6.8° (range, 6.3-7.4°), 10.3° (range, 9.8-10.8°), and 14.1° (range, 13.6-14.6°) at C3 vertebrae; 6.8° (range, 6.2-7.5°), 10.7° (range, 10.0-11.5°), and 14.1° (range, 13.4-14.8°) at C4 vertebrae; 6.6° (range, 6.0-7.2°), 10.1° (range, 9.3-10.8°), and 13.5° (range, 12.8-14.3°) at C5 vertebrae and 7.6° (range, 6.9-8.3°), 10.9° (range, 10.3-11.6°), and 14.3° (range, 13.7-15.0°) at C6 vertebrae. The recommended lateral angulations for Roy-Camille, Magerl, and An are 10°, 25°,and 30°, respectively. Statistically, there is a higher risk of vertebral foramen violation with the Roy-Camille technique at C3, C4 and C6 levels, P < 0.05.
CONCLUSIONS: Magerl and An techniques have a wide margin of safety. Caution should be practised with Roy-Camille's technique at C3, C4, and C6 levels to avoid vertebral vessels injury in Asian population.

Right vertebral artery injury as a result of misplaced internal jugular vein catheter withdrawal

Central venous cannulation is a common procedure done for various medical indications. The use of the central venous cannula is associated with various immediate complications such as pneumothorax, vascular injury, and arrhythmia. The following is an unusual case of delayed presentation of a right vertebral artery injury due to central venous cannulation which resulted in a posterior circulation stroke. This is a condition that can be difficult to diagnose and has a significant impact on patient's quality of life. Clinicians and radiologists should be alert to this possibility to prevent further morbidity resulting from the iatrogenic injury.
