Abstract:

【Abstract】 Objective To analyzed the application of MSCT volume measurement in comparing the effects of percutaneous vertebroplasty and kyphoplasty in the treatment of osteoporotic vertebral compression fractures. Methods Retrospective data of 34 patients with osteoporotic vertebral compression fractures were analyzed in our hospital during December 2007 to December 2012. The patients were treated by percutaneous vertebroplasty and kyphoplasty,and received MSCT examination within 72 hour after operation..By the CT volume measurement, the dispersion coefficient was calculated by the volume of bone cement introduced and dispersion volume..The differences of the dispersion coefficient and VAS scores.(preoperative minus the postoperative).between two groups that treated by PVP or PKP were performed Independent-Samples T Test, and the difference of the bone cement dispersion coefficient and VAS scores between two groups was compared..The relationship between the bone cement dispersion coefficient and VAS score changes were analyzed by Spearman Correlation Analysis. Results The bone cement dispersion coefficient between two groups of different operation method was statistically significant.(P=0.005). The differences of VAS scores between two groups was statistically significant (P=0.026). The relationship between the bone cement dispersion coefficient and VAS scores were certain relationship.(r=0.465)..Conclusion The bone cement dispersion coefficient of PVP is less than PKP. Bone cement dispersion coefficient can be used as a reference indicator of evaluating the effect of vertebral plasty.
