Objective To explore the application effect of modified "eggshell" technique in osteoporotic vertebral compression fracture patients with percutaneous kyphoplasty (PKP).
Methods A total of 86 patients with osteoporotic vertebral compression fracture were randomly divided into control group (n=43) and observation group (n=43). The control group was treated with PKP, and the observation group was treated with PKP based on modified "eggshell" technology. At 7 days after operation, the surgical indexes, Visual Analogue Scale (VAS) score, Oswestry Dysfunction Index (ODI) questionnaire, Cobb angle, percentage of anterior edge of vertebral body and incidence of complications were compared between the two groups.
Results There were no significant differences in the amount of bleeding, operation time and time to bed-off activity between the two groups (P>0.05), but the perfusion amount of bone cement in the observation group was significantly higher than that in the control group (P < 0.05). The VAS, ODI and Cobb angle of the observation group at 7 days after operation were significantly lower than those of the control group, and the percentage of anterior edge of vertebral body was significantly higher than that of the control group (P < 0.05). The total incidence rate of postoperative complications such as leakage, infection, lower limb radiation pain, lower limb numbness and muscle strength decline in the observation group was significantly lower than that in the control group (P < 0.05).
Conclusion Modified "eggshell" technology has the advantages of less trauma, less pain and complications, which can improve the vertebral function of osteoporotic vertebral compression fracture patients with PKP.
