BACKGROUND: The treatment of upper cervical spine disorders through a posterior pedicle fixation approach have been carried out in some domestic large hospitals, but this surgery is still considered as a difficulty of cervical spine surgery. In order to minimize the risk of surgery, the authors designed a program of individual operations, and combined with self-developed pedicle locating and directing speculum to determine precise intraoperative position of pedicle screws, and no report is found by searching related database in China.OBJECTIVE: To improve the one-time success rate of internal fixation screws, to investigate the biomechanical effect of the implant, to formulate a simple, practical, individual protocol for atiantoaxial pedicle screw-plate system based on related data. METHODS: A total of 31 patients were recruited from Department of Orthopaedics in the 251 Hospital of Chinese PLA, between January 2002 and September 2006. Under the guidance of self-made atlantoaxial locating and directing speculum, the entrance point and angle for screw insertion, as well as screw diameter and length were determined according to the results of X-ray and CT measurement. Atlas pedicle screw was inserted at left (19.93±1.32) mm, and right (19.16±1.3) mm; Atlas pedicle screw insertion angle to inside was left (23.72±2.09)°, and right (23.35±1.91)°; Atlas pedicle screw insertion angle to side of head was (9.00±1.20)°. Axis pedicle screw was inserted at left (13.14±0.82) mm, and right (13.85±0.79) mm; Axis pedicle screw insertion angle to inside was left (24.52±1.26)°, and right (20.42±1.42)°; Axis pedicle screw insertion angle to side of head was (25.00±3.00)°.RESULTS AND CONCLUSION: ①Totally 124 pedicle screws were implanted into 31 patients, and 122 screws were of one-time success. The precision rate was 98.39%. Two screws were secondly inserted because of cutting lateral cortical bone of pedicle for deviation of inward angle. ②Occipital neuralgia was found in 2 cases postoperatively and cured after one month of treatment;screws penetrated atlas left vertebral lateral wall in 2 cases, no spinal or vertebral artery injury was found. ③Radiographs showed that atlas was completely reduced in all patients, and apposition of dentoid process of axis fracture was good. CT films showed the screws a good location to the vertebrarterial spinal cord. ④The follow-up visit was averaged of 10.5 months. Bony fusion was found in all patients. No screw-plate breakage was found. No inflammatory or rejection reactions occurred.⑤By JOA scale, there were 16 cases of excellent, 12 cases of good, 2 cases of fine, and 1 case of poor. The excellent and good rate was 90%. It is suggested that the success rate of atlantoaxial pedicle screw-plate mplantation can be improved through a biomechanical angle.

Objective: To analyze the characteristics, treatment and prognosis in patients with essential thrombocythemia (ET) combining myocardial infarction (MI).
Methods: A total of 10 patients with ET combining MI treated in our hospital from 2003-01 to 2015-07 were retrospectively studied. The basic clinical information with major admission complaints, previous history and peripheral platelet counts were recorded;echocardiograph, coronary angiography (CAG), application of anti-platelet drugs and platelet reductive therapy with the prognosis were recorded in all patients.
Results: There were 6 male and 4 female with a mean age of (55.3 ± 9.7) years, 7 patients with AMI and 3 with old MI. The platelet counts at admission were (500-599) × 109/L in 3 patients, (600-699) × 109/L in 1 patient, (700-799) × 109/L in 3 patients, (800-899) × 109/L in 1 patients, (900-999) × 109/L in 1 patient and more than 1000 × 109/L in 1 patient. Echocardiograph indicated that 5 patient had LVEF≤50%and 5 had LVEF>50%. CAG revealed that there were 9 cases with left anterior descending involved, 2 with circumlfex involved and 5 with right coronary involved. All patients received dual anti-platelet drugs before operation, 4 had hydroxyurea for (20-30) days before operation and no post-operative cardiovascular events occurred;6 patients without hydroxyurea medication and 1 of them was re-hospitalized for angina pectoris and 2 had progressed coronary lesions.
Conclusion: Application of platelet reductive therapy at before and after interventional treatment may improve the prognosis in patients with ET combining MI.
