Abstract Objective To investigate the effect of bone cement diffusion in osteoporotic vertebral fractures line on percutaneous vertebroplasty (PVP). Methods Fifty-two patients with osteoporotic vertebral compression fractures (OVCF) from September 2014 to March 2016 in our hospital were recruited in the research. All patients underwent PVP treatment. According to multiplanar reconstruction CT or MRI evaluation, 39 cases were considered good dispersion of bone cement (good dispersion group)and 13 cases were considered poor dispersion of bone cement ( poor dispersion group).Visual analogue scale (VAS) score, Oswestry disability index (ODI) and local kyphosis Cobb angle were measured in the two groups. Results Bone mineral density of the good dispersion group was (-3.20±1.13) T, which was significantly lower than that of the poor dispersion group (P<0.05). The VAS and ODI scores on d₄ post-operation in the good dispersion group were (2.60±0.55) points and (12.82±1.41) points, respectively, which were significantly lower than those in the poor dispersion group (P<0.05).There were no significant differences between the two groups in terms of VAS score and ODI score preoperatively and at the final follow-up after surgery (P>0.05).In the good dispersion group, local kyphosis Cobb angle on d₄ post-operative and the final follow-up were (6.30±2.11)° and(6.51±1.84)° , respectively, which were significantly lower than those in the poor dispersion group (P<0.05). Refracture incidence rates in the good dispersion and poor dispersion group were 5.13% and 7.69%,respectively; the difference was not statistically significant (P>0.05); Vertebral collapse incidence rates in the good dispersion group was 10.26%, which was significantly lower than that in the poor dispersion group (38.46%); the difference was statistically significant (P<0.05). Conclusion PVP can improve the function of patients with osteoporotic vertebral compression fractures. Poor dispersion of bone cement in the fracture line will affect the short-term efficacy, which may lead to postoperative kyphosis deformity.
