| Objective:To assess the clinical and radiographical outcomes in treating patients with osteoporotic vertebral compression fractures (OVCF)by C- pod Kyphoplasty.Method:15 patients (12 women and 3 men) suffered from OVCFs were treated by C- pod Kyphoplasty from December 2007 to April 2010. Mean patient age was 72.2years (range, 56–82 years). A total of 15 painful OVCFs (1 in T9; 2 in T11; 5 in T12; 5 in L1; 2 in L2) were enrolled in our study. All OVCFs except two had an intact posterior wall, and MRI demonstrated marrow edema on fat-saturated T2-weighted sequences. Preoperative and postoperative of visual analogue scores (VAS), Oswestry Disability Index, and radiographic results were compared.Result:All patients got significant pain relief .VAS score improved from 8.9±1.4 points to 2.1±1.3 points before and after operation, and was 2.2±1.5 points at final follow- up. There was a significant improvement between the preoperative and postoperative values(P<0.05), but no difference between the postoperative and final follow-up values(P>0.05).Comparison of preoperative and postoperative ODI scores showed significant improvement (86.1±9.7 vs. 30.5±7.6). The final follow-up ODI was 32.7±8.4。The height of anterior column of the vertebrae increased from pre-operative 14.50±1.34 mm to post-operative 23.20±1.12 mm and was 22.82±0.85 mm at final follow- up. There was a significant improvement between the preoperative and postoperative values(P<0.05), but no difference between the postoperative and final follow-up values(P>0.05).The kyphotic angle was improved from pre-operative 28.50±1.85°to post-operative 11.30±1.40°and 12.48±0.70°at final follow- up. There was a significant improvement between the preoperative and postoperative values(P<0.05), but no difference between the postoperative and final follow-up values(P>0.05).Conclusion:C-pod Kyphoplasty was a safe and efficacious procedure for painful OVCFs to prevent bone cement leakage with satisfied short-term results。... |
