Abstract

We compared the biomechanics between improved percutaneous vertebroplasty (improved PVP) and traditional percutaneous kyphoplasty (PKP) in the treatment of vertebral peripheral wall damage-type osteoporotic vertebral compression fracture (OVCF). A total of 15 vertebral peripheral wall damage-type OVCF models of new calves (12-14 weeks) were treated with a decalcifying agent (Shandon TBD-1) with the vertebral compression fracture. The vertebral volume and anterior height before modeling, and the vertebral BMD before and after modeling were measured. The models were randomly divided into three groups: the improved PVP group (Group A), the traditional PKP group (Group B) and the control group (Group C). BMD of Groups A, B and C after decalcification was significantly lower than that before decalcification (P<0.05). There were no significant differences in BMD before and after decalcification among Groups A, B and C (P>0.05). There was no significant difference in the initial strength and stiffness among the three groups (P>0.05). The postoperative strength of Groups A and B was 1.036±300 and 1.045±200 N, respectively, which was significantly higher than the initial strength (P<0.05). The postoperative stiffness of Groups A and B was 395±250 and 470±270 N/mm, respectively, which was slightly lower than the initial stiffness, however, the differences were not statistically significant (P>0.05). In the comparison of postoperative strength and stiffness between Groups A and B, the postoperative strength in Group A was lower than that in Group B; differences were not statistically significant (P>0.05); there was no significant difference in the postoperative stiffness between Groups A and B (P>0.05). There were no significant differences of injection of bone cement between the two groups (P>0.05). Therefore, an improved PVP can basically realize the curative effects of traditional PKP in the treatment of vertebral peripheral wall damage-type OVCF, which can be used as clinical reference.
