Abstract:
Objective To research the risk of osteopo'rotic vertebral fractures with PKP after the PMMA injected location and dose of occurrence of vertebral refracture.Methods 78 cases of vertebral osteoporotic thoracolumbar vertebral compression fracture patients with PKP treatmentin were selected.According to position of postoperative PMMA in the vertebral body,they were divided into the side of the group of 35 patients and a median group of 43 patients.Compared two groups of patients before and after surgery,VAS,ODI score,the SI and Cobb angle and analyzed the PMMA leakage occur with the relationship of the amount of bone cement injected.Results There were significant differences in visual analogue pain scale(VAS),Oswestry disability index(ODI),sagittal index(SI) and Cobb angle of each group preoperatively versuspostoperatively (all P ＜ 0.05).No statistical difference was noted in the VAS,ODI,SI and Cobb angle between two groups preoperatively versus postoperatively(all P ＞ 0.05).PMMA injection volume between the the leakage group and the non-leakage patients had statistically significant difference (P ＜ 0.05).Conclusion PKP could obtain better clinical therapeutic effect in osteoporotic vertebral fractures treatment.Different PMMA positions had no significant influence on the therapeutic results.PMMA injected dose is a risk factor for bone cement leakage,which will increase the risk of vertebral fractures again.
