Abstract:

Objective To compare the ability of geometry deformity correction of percutaneous vertebroplasty (PVP) and percutaneous kyphoplasty (PKP) for middle-aged and old women with osteoporotic vertebral compression fractures (OVCF) and explore the correlation between the complete correction of geometry deformity and the relief of clinical symptoms. Methods A total of 99 middle-aged and old women with OVCF who underwent PVP or PKP were selected and divided into the PVP group (n=56) and PKP group (n=43) according to the surgical procedure. McCloskey-Black quantitative judgment of percutaneous morphometric shape was adopted to measure the height of compressed vertebra before and after surgery. The geometric types of vertebrae were classified into the morphometric normal shape and morphometric compressed shape. The variations of morphometric shapes of compressed vertebrae and the ability of geometry deformity correction of two surgical procedures were compared. The correlation between the complete correction of geometry deformity and the relief of clinical symptoms was compared by the visual analogue scale (VAS). Results A total of 22 patients acquired complete morphometric correction after surgery and the overall correction rate was 22.22%. The correction rate of the PKP group (34.15%) was higher than that of the PVP group (14.81%) and the difference was statistically significant (P<0.05). The VAS scores of patients after surgery were significantly lower than those before surgery (P<0.05). The VAS scores of patients with complete and incomplete morphometric correction after surgery were 2.31±0.93 and 2.60±0.92, respectively. The difference was statistically insignificant (P>0.05). Conclusion Both minimally invasive PKP and PVP can significantly correct the morphometric deformity of compressed vertebrae. The ability of geometry deformity correction of PKP is better than PVP. There is no clear correlation between the complete correction of geometry deformity and the relief of clinical symptoms.
