Objective A design of guide wire localization apparatus for the internal fixation of dens fractures. Methods From October 1999 to February 2000, 5 cases of dens fractures were treated by anterior internal fixation using cannulated compression screws; 4 cases were of Anderson typeⅡ and 1 case was typeⅢ . The guide wire localization apparatus was used for all of the patients during operations. Results The operating time was 2 to 2.5 hours, averaging 2 hours 15 minutes. The amount of bleeding was 20 to 100 ml, averaging 60 ml. The time of follow-up was 5 to 9 months, averaging 6.7 months. The locations of all the 5 cannulated compression screws were excellent, positioning in the center of the odontoid process without deviation. 4 cases healed normally and 1 had delayed bone healing. Conclusion The use of a guide wire location apparatus increased the accuracy of internal fixation of screws in dens fracture, decreased X-ray to radiation to the bodies, and reduced the possibility of pollution in operation.

Objective To evaluate the clinical effect and application value of internal fixation of Magerl combined with Brooks technique for atlantoaxial instability. Methods A total of 18 patients with atlantoaxial instability, reducible atlantoaxial dislocation with reduction after traction and irreducible atlantoaxial dislocation with traction reduction after anterior laxation were treated with internal fixation of Magerl combined with Brooks technique using autologous bone grafts. Results The patients were followed up for an average 18 months (6-36 months). Screw was probably cut into the vertebral artery in one case. The guide needle was cut into the pharynx due to incorrectly penetrating the C 1 anterior arch of atlas for 3.5 cm in one case but no early complications such as spinal cord injury and local infection occurred. The spinal cord function improvement was marked in 3 cases, good in 9, mild in 4 but unchanged in 2. No case got worse. There were no loosening or break of the screw and cable. Conclusions Combined fixation of Magerl and Brooks techniques reaches three-point fixation and improves the reduction effect. It is necessary to use the combined fixation with best biomechanical stability for atlantoaxial dislocation patient with reduction or near reduction if the structure of the posterior arch of C 1,2 is intact.

Objective To investigate the relationship between metabolic syndrome (MS) and female subclinical carotid atherosclerosis. Methods A total of 835 female subjects were enrolled in this study. MS was defined based on the ATP Ⅲ criteria. Age groups were <45,45 to 65,and ≥65 years. The participants were evaluated by the number of components of MS and clusters of MS components. Measurement of carotid arteries with B-mode ultrasound imaging was performed. Intima-media thickness and plague of the carotid arteries were regarded as the indicators of subclinical carotid atherosclerosis. Results The prevalence of carotid atherosclerosis, MS components and MS was significantly increased with the increased age. After age was adjusted, multiple logistic regression analysis showed that every component of MS was independently associated with carotid atherosclerosis; the increased waist circumstance and blood pressure and reduced HLD showed stronger effect. The prevalence of carotid atherosclerosis was increased with increasing number of components of MS. When compared to the 0 MS component group,the odds ratio (OR)of carotid atherosclerosis of the groups with 1, 2,3,4, or 5 components were 1.4,2. 0,3.4,5. 7 and 7. 1,respectively. The altered cluster components of MS impacted differently on carotid atherosclerosis. The clusters of components of MS with increased waist circumstance were more frequent than without ones. Conclusion Every component of MS may be an independent risk factor of carotid atherosclerosis;increased components of MS could contribute higher odd risk to carotid atherosclerosis; clusters of MS components might show different impacts on carotid atherosclerosis.
