This report is being filed after the review of the following journal article: hoppe s., et al (2016),lavage prior to vertebral augmentation reduces the risk for cement leakage, european spine journal volume 25 (11), pages 3463¿3469 (switzerland).This study aims to assess radiologically the filling patterns of the cement and the cement leakage rates in patients treated with vp, kp or stenoplasty (sp) with and without lavage.From january 2012 to august 2014, a total of 142 consecutive patients with osteoporotic vcf who were treated were included in the study.The newly developed lavage technique was applied prior to cement application in 64 patients with 116 vertebrae.These were assigned to the interventional ¿¿lavage¿¿ group.A conventional cement injection technique was used to treat 78 patients with 99 vertebrae, who were assigned to ¿¿controls¿¿ group.Three types of vertebral augmentation were used: vp, kp and sp.In the kyphoplasty group a standard kyphoplasty device (synflate¿vertebral balloon system, synthes (b)(4)), for the stenoplasty a standard stenoplasty device (vbs¿vertebral body stenting system, synthes, bettlach, switzerland) and cement preparation was performed according to the manufacturer¿s manual (vertecem v+,synthes, (b)(4)).The following complications were reported as follows: vertebrae with a leakage: overall 44 in lavage group, 83 in control group.Vertebrae with a leakage: venous 15 in lavage group, 31 in the control group.Vertebrae with a leakage: cortical defect 20 in lavage group 63 in the control group.Vertebrae with a leakage: intradiscal 14 in lavage group 15 0.51 in the control group.The extent of leakage, overall: 27 in lavage group 36 0.1 in the control group.Extent of leakage, overall: 2¿10 mm 14 in lavage group, 40 in control group.Extent of leakage, overall: 10 mm 2 in lavage group 7 in control group.This report is for an unknown synthes synflate¿vertebral balloon system, standard stenoplasty, vbs¿vertebral body stenting system and vertecem v+.This report is for one (1) unk - biomaterial - cement: vertecem v+.This report is 1 of 1 for (b)(4).
