Abstract：Objective To compare the efficacy of unipedicular percutaneous kyphoplasty (PKP) with the bipedicular one in the treatment of osteoporotic vertebral compression fractures(OVCF).Methods Totally 96 patients with OVCF in our hospital were selected and divided into two groups according to their joining numbers.Odd numbers were the control group,and even numbers were the observation group,with 48 patients in each group.Patients in the control group were treated with bipedicular PKP,whereas the control group was treated with unipedicular PKP,and all the patients were given anti-osteoporosis medication treatment.Gender,age,weight,fracture sites and other general data were compared.VAS score,ODI index,SF-36 scale,Cobb's angle,as well as the operation time,intraoperative fluoroscopy times and bone cement injection and other data were compared,and the curative effect was analyzed.Results There was no difference in the general data such as gender,age,weight and fracture sites between the two groups(P>0.05);no difference was found in the VAS,ODI,SF-36,anterior/medium height of the vertebrae body,and Cobb's angle.Compared with the data before operation,the above indexes of two groups were all significantly improved(P<0.05),but the differences between the two groups were not significant(P>0.05).The operation time,intraoperative fluoroscopy times and bone cement injection in the control group were (42.2±10.3) min, (18.6±5.4),(4.5±0.5) mL,respectively,significantly different from those in the observation group[(68.8±12.5) min,(48.9±6.2),(6.1±0.6) mL,P<0.05].Postoperative adjacent vertebral fracture occurred again in 6 cases in the control group,while only in one case in the observation group,and there was statistical significance (P<0.05).No adverse reaction happened in either group.Conclusion Compared with bipedicular PKP,the unipedicular one is more simple and efficient to get the same result,and it is safe and worthy to be promoted.
