| 【Abstract】 Objective：To evaluate the clinical and radiographical outcomes of fabric pod kyhoplasty for osteoporotic vertebral fractures（OVFs）.Method：13 patients（11 females and 2 males） who sustained OVFs underwent fabric pod kyphoplasty between December 2007 and April 2010.The mean age was 72.2 years old（range，56-81 years）.A total of 15 painful OVFs（1 T9，2 T11，5 T12，5 L1，2 L2） were enrolled in our study.Except ford 2 patients，all patients had an intact posterior vertebral wall，and MRI showed marrow edema on fat-saturated T2-weighted sequences.Preoperative and postoperative of visual analogue scores（VAS），Oswestry disability index（ODI），and radiographic results were compared.Result：All patients got significant pain relief. The VAS score improved from 8.9±1.4 to 2.1±1.3 after operation，and was 2.2±1.5 at the finall follow-up. There was significant improvement between the preoperative and postoperative values（P<0．05），but no difference between postoperative and final follow-up values were noted（P>0．05）．Compared with preoperative ODI scores，the postoperative ones 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±1.34mm to post-operative 23.20±1.12mm and 22.82±0.85mm at final follow-up.There was significant improvement between the preoperative and postoperative ODI values（P<0．05），but no difference between the postoperative and final follow-up values were noted（P>0．05）．The kyphotic angle 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 significant improvement between preoperative and postoperative values（P<0．05），but no difference between the postoperative and final follow-up values were noted（P>0．05）．Conclusion：Fabric pod kyphoplasty is safe and reliable for painful OVFs，which can prevent bone cement leakage and ensure satisfying short-term results. |
