Abstract：Objective To compare the difference of polymethylmethacrylate ( PMMA) leakage after percutaneous vertebroplasty ( PVP) for osteoporotic vertebral compression fractures ( OVCFs) with and without intravertebral vacuum cleft (IVC).Methods In total, 284 patients treated for single-OVCF, among whom 104 patients were enrolled in IVC group and 180 patients in non -IVC group, were retrospectively reviewed .The follow -up period was at least 2 years. Plain X-rays and CT were postoperatively performed to investigate PMMA distribution pattern within the affected verte-brae, the presence of PMMA leakage and leakage types .Furthermore, the difference between two groups was compared . Results The local solid lump distribution pattern accounted for 65.4% in IVC group and 24.4% in non-IVC group. The PMMA leakage occurred in 18 (18/104, 17.3%) patients in IVC group and 30 (30/180, 16.7%) patients in non-IVC group, without significant difference (P>0.05).The leakage types that frequently occurred were intradiscal (12/18, 66.7%) in IVC group and perivertebral venous (22/30, 73.3%) in non-IVC group.A significant difference was found in leakage type between the 2 groups.Conclusion The incidences of PMMA leakage in osteoporotic compression fractures with and without IVCs were similar .However, leakage type differs.
