Abstract:
Objective:To evaluate the clinical value of posterior articular screwfixation in patients with atlantoaxial instability.Methods:From January 2005 to June 2009,43 patients in our hospital with atlantoaxial instability were treated by posterior screw fixation.The clinical values were accessed by radiographic imaging,JOA and VAS score in 5 years follow-up.Results:No intraoperative complication occurred in 43 patients.Postoperative X-ray film showed anatomical reduction in 39 patients,correction of most of dislocation in 4 patients,all the internal fixation were in good position.Spinal MRI showed spinal cord compression were back to normal.After 2 to 3 months,atlanto-axial were vertebraed.After 6 months,the patient's cervical spine function(t=14.099,P=0.000)and pain conditions(t =19.335,P=0.000)were significantly improved compared with before surgery,the average improvement rate was 86.1%?5.2%.Conclusion:The posterior screw fixation in the treatment of atlantoaxial instability is effective and reliable,have less complications and can be used as an effective surgical procedure.
