Comparison of clinical effects between unipedicular and bipedicular approach to percutaneous vertebroplasty for osteoporosis vertebral compressive fractures / 实用医学杂志

ABSTRACT

Objective To compare the clinical effect and safety of percutaneous vertebroplasty between unipedicular and bipedicular approach for patients with osteoporosis vertebral compressive fractures. Methods A retrospective study was carried out on 147 patients with single osteoporotic vertebral compressive fractures from 2008 to 2014. Ninety-five cases were treated by PVP via a unipedicular approach (unipedicular group) and 52 cases were treated by the bipedicular approach (bipedicular group). The operation time, Cobb, frequency of X-ray exposure,complications like bone cement and postoperative VAS score were compared. Results No significant differences on the VAS score, cobb and complications were found (P > 0.05). However, there were significant differences on the operation time and X-ray exposure frequency (P<0.05). Conclusions No significant differences on clinical effects were found between the unipedicular and the bipedicular approach to percutaneous vertebroplasty for osteoporosis vertebral compressive fractures. However, the unipedicular approach can shorten the operation time and reduce X-ray exposure.
