Abstract [Obj ective]To explore the feasibility and clinical efficacy of percutaneous vertebroplasty(PVP) in the diagnosis and treatment of nonunion of osteoporotic vertebral compression fracture(OVCF).[Methods]A total of 7 patients with nonunion of osteoporotic vertebral fractures undergoing PVP from May 2009 to May 2013 were analyzed retrospectively.There were 2 males and 5 females.The mean age was 72.5 years(61~88 years).The fracture vertebrae were 3 cases in T12 ,3 cases in L1 and 1 case in L2 .The disease duration was 15~23 months.All patients received X-rays,CT and MRI examination.The surgical result was evaluated by visual analogue scale(VAS),anterior vertebral height(AH)and wedge angle(WA).[Results]All patients were operated successfully without severe complications.All patients were followed up for 5~35 months (mean 1 5 .5 months).Postoperative pain was alleviated obviously.Pain VAS before and at d1 after operation was (8.10±1.50)and (1.25±1.04)respectively,and there was significant difference between them(P <0.05).The VAS at final follow up was (1.15±0.87),but there was no significant difference between the fi-nal follow up and post-operation(P>0.05).Compared with before operation,AH and WA after operation had no obvious improvement(P>0.05).There was no significant difference in AH and WA between the final follow up and post-operation(P>0.05).[Conclusion]PVP can obviously improve back pain caused by non-union of OVCF,but has no obvious effect on the recovery of the height of the diseased vertebra.
