Objective In the classic percutaneous kyphoplasty

the "eggshell" technique was used to optimize balloon formation

and various clinical and imaging indicators were observed to explore the efficacy of the new method. Methods From August 2018 to January 2019

48 cases of osteoporotic thoracolumbar vertebral fractures treated in our department were observed.According to the different surgical methods

they were divided into the observation group and the control group.In the observation group (24 cases)

"eggshell" technique was used to optimize balloon formation during percutaneous kyphoplasty.In the control group(24 patients) were treated with the classic percutaneous kyphoplasty.Visual analogue scale score of pain(VAS)

Oswestry disability index(ODI) and imaging Genant′s semiquantitative method were used to determine the degree of vertebral deformity and bone cement permeability.Results There was no significant difference in VAS and ODI scores between the two groups(P>0.05).The bone cement leakage rate in the observation group was 12.5%

while it was 25% in the observation group

and the difference was statistically significant(P<0.05).In the observation group

the percentage of degree Ⅰ after Genant′s semiquantitative spell was 82%

and it was 75% in the control group

with statistically significant difference (P<0.05).Conclusion In percutaneous kyphoplasty

"eggshell" optimized balloon shaping technique is used to treat osteoporotic thoracolumbar vertebral fracture

and the clinical effect is satisfactory

which is an ideal treatment method.
