Background: Percutaneous vertebroplasty is a widely used vertebral augmentation procedure for treating osteoporotic vertebral compression fractures (OVCFs). But high cement leakage rate caused by a low-viscosity cement and high injection pressure has limited its general use. Balloon kyphoplasty (BKP) and high-viscosity cement vertebroplasty (HVCV) are 2 modifications of vertebroplasty designed to decrease cement leakage. Objective: To assess the safety and efficacy of HVCV compared with BKP. Study Design: A prospective cohort study. Setting: Department of Spine Surgery, an affiliated hospital of a medical university. Method: One hundred seven patients suffering from painful OVCFs were randomly assigned into HVCV or BKP groups. Visual Analog Scale (VAS), Oswestry Disability Index (ODI), cement leakage, and vertebral height restoration were evaluated. All occurring complications and injected cement volumes were recorded. The follow-up time was one year. Results: VAS and ODI scores improved in both groups, and did not differ significantly between the 2 groups. More cement was used in the BKP group than in HVCV group (4.22 vs. 3.31 mL, P < 0.0001). The incidence of cement leakage in the HVCV group was lower than that of the BKP group (13.24% vs 30.56%, P < 0.05). No symptomatic cement leakages occurred in the HVCV group. In the BKP group, one patient experienced discogenic back pain related to a disc leak, and another patient had asymptomatic cement emboli in the lung related to venous leakage. The mean compression rate before the procedure was 29.98% in the HVCV group and 28.67% in the BKP group (P = 0.94). The vertebral height was improved significantly and maintained at one-year follow-up in both groups. BKP was more effective in vertebral height restoration than HVCV (44.87% vs. 23.93%, P < 0.0001). There was one case of a new adjacent vertebral fracture in the HVCV group (2%), and 4 cases of new nonadjacent vertebral fractures in the BKP group (7.84%) (P = 0.18). Limitations: A single-center and relatively small-sample size study. Conclusion: HVCV and BKP are safe and effective in improving quality of life and relieving pain. HVCV has a lower cement leakage rate, whereas BKP is more effective in vertebral height restoration. Subsequent fractures are not different between the 2 groups.

AbstractSevere osteoporotic vertebral compression fractures (OVCFs) were considered as relative or even absolute contraindication for vertebroplasty and kyphoplasty and these relevant reports are very limited. This study aimed to evaluate and compare the efficacy of vertebroplasty with high-viscosity cement and conventional kyphoplasty in managing severe OVCFs. 37 patients of severe OVCFs experiencing vertebroplasty or kyphoplasty were reviewed and divided into two groups, according to the procedural technique, 18 in high-viscosity cement percutaneous vertebroplasty (hPVP) group and 19 in conventional percutaneous kyphoplasty (cPKP) group. The operative time, and injected bone cement volume were recorded. Anterior vertebral height (AVH), Cobb angle and cement leakage were also evaluated in the radiograph. The rate of cement leakage was lower in hPVP group, compared with cPKP group (16.7% vs 47.4%, P = 0.046). The patients in cPKP group achieved more improvement in AVH and Cobb angle than those in hPVP group postoperatively (37.2 ± 7.9% vs 43.0 ± 8.9% for AVH, P = 0.044; 15.5 ± 4.7 vs 12.7 ± 3.3, for Cobb angle, P = 0.042). At one year postoperatively, there was difference observed in AVH between two groups (34.1 ± 7.4 vs 40.5 ± 8.7 for hPVP and cPKP groups, P = 0.021), but no difference was found in Cobb angle (16.6 ± 5.0 vs 13.8 ± 3.8, P = 0.068). Similar cement volume was injected in two groups (2.9 ± 0.5 ml vs 2.8 ± 0.6 ml, P = 0.511). However, the operative time was 37.8 ± 6.8 min in the hPVP group, which was shorter than that in the cPKP group (43.8 ± 8.2 min, P = 0.021). In conclusion, conventional PKP achieved better in restoring anterior vertebral height and improving kyphotic angle, but PVP with high-viscosity cement had lower rate of cement leakage and shorter operative time with similar volume of injected cement.

Abstract Objective To evaluate the efficacy of percutaneous kyphoplasty (PKP) for thoracolumbar osteoporotic vertebral compression fractures (OVCFs) via unilateral versus bilateral approach. Methods All patients who underwent PKP surgery for OVCFs in our hospital between June 2016 and December 2018 were included in this study. The pedicles were divided into two groups according to the manner of vertebral body puncture, which were as follows: unilateral pedicle puncture group (unilateral group, n=47) and bilateral pedicle puncture group (bilateral group, n=39).The operative time, amount of cement perfusion, correction angle of kyphosis, pain score before and after surgery, and leakage rate of bone cement were evaluated in all patients. The average follow-up was 19 months (range 13-34 months). Results The average age of patients who met the inclusion criteria, but not the exclusion criteria, was 76 years, and a total of 121 vertebral bodies were studied. There were 7 cases of postoperative bone cement leakage (unilateral group, 14.9%) and 6 cases of postoperative bone cement leakage (bilateral groups, 15.4%). There were differences in operative time and amount of cement perfusion between the two groups were statistically significant (P<0.05). There was no significant increase in age, body mass index, pain index during follow-up, treatment outcome, correction angle of kyphosis, and cement leakage rate between the two groups (P>0.05). Moreover, there was no significant difference in sex and bone cement leakage rate between the two groups by Pearson x 2 test (P>0.05). Conclusion Patients with OVCFs could obtain similar satisfactory clinical results via both unilateral and bilateral PKP approaches. However, the unilateral PKP approach is more advantageous as it has a shorter operative time, requires lesser cement volume, causes minimal trauma, is less costly, and results in lesser complications than the bilateral approach.

Institutional Review

Background: Both vertebroplasty and balloon kyphoplasty have been described for treatment of vertebral compression fractures. Vertebroplasty is known for its high leakage rate compared with balloon kyphoplasty. In vitro studies have shown that high-viscosity cements significantly decrease the incidence of cement leakage and increase the predictability of cement fill in cancellous bonelike substrates compared with low-viscosity cements. Objective: This study compares the incidence and pattern of cement leakage in cases treated with standard balloon kyphoplasty (BKP) and a novel vertebral augmentation procedure, radiofrequency targeted vertebral augmentation (RF-TVA). Study Design: Retrospective evaluation of postoperative radiographs. Setting: Single center inpatient and outpatient population. Methods: Two methods of vertebral augmentation were utilized. Conventional bipedicular BKP and RF-TVA, a novel unipedicular technique which uses a navigational osteotome to create targeted, bone sparing cavities and RF energy to deliver an ultra-high viscosity cement at a consistent rate via a remote controlled, automated hydraulic delivery system. Postoperative radiographs of patients treated with the 2 techniques were critically analyzed for the incidence and location of cement leakage. Eighty consecutive patients with 106 treated levels were included. Thirty-five patients with 49 levels in the BKP and 45 patients with 57 levels in RF-TVA group were evaluated. Results: Leakages less than 1-2 mm were not reported since they may not represent any clinical significance. In the BKP group, 6 leakages (12%) were reported (3 discal, 2 venous, one paravaertebral, and no epidural). In the RF-TVA group, a total of 3 leakages (5%) were reported, (one discal, 2 venous, no paravaertebral or epidural). Using contingency analysis for leakage per level, there was a statistical difference for leakage between RF-TVA and standard BKP, P < 0.01. Limitations: Retrospective study, single center. Conclusions: The RF-TVA technique may provide an approximately 50% reduction in leakage rate when compared to standard BKP. This may be related to the combination of controlled delivery of radiofrequency activated (high viscosity) cement at a fixed, low rate of delivery into sitespecific channels created using a navigational osteotome. Additionally, based on the unipedicular access and remotely controlled cement delivery RF-TVA may decrease procedural invasiveness and physician radiation exposure, respectively. Institutional Review: This study was approved by the Institutional Review Board. Key words: Balloon kyphoplasty, radiofrequency targeted vertebral augmentation, compression fractures, cement leakage

Abstract Background A systematic review and meta-analysis to assess the pros and cons of percutaneous vertebroplasty (PVP) versus kyphoplasty (PKP) for osteoporotic vertebral compression fractures (OVCFs) with intravertebral cleft (IVC) including all available evidence from controlled trials. Methods Databases including Pubmed, Embase, Cochrane Library, China National Knowledge Infrastructure (CNKI), and Wanfang Data were searched to identify relevant studies comparing PVP and PKP for OVCFs with IVC. The outcomes mainly included visual analog scale (VAS), Oswestry Disability Index (ODI), local kyphotic angle (LKA), rate of vertebral height (VH%), and adverse events. Results Nine studies enrolling 688 patients were eligible for meta-analysis. The results indicated no significant differences between the two groups in the short-and long-term VAS, ODI, LKA, or VH% (P > 0.05). Compared with PVP, PKP was associated with significantly longer operation time (P < 0.05), higher cost (P > 0.05), and more injected cement volume (P < 0.05). In terms of adverse events, PKP has a lower risk of cement leakage (P < 0.05), while with no significant difference in adjacent-level fracture rates (P > 0.05). Conclusion The two procedures have similar short- and long-term pain relief, functional recovery, local kyphosis correction, and vertebral height maintenance in OVCFs with IVC. PKP is superior to PVP for the injected cement volume, and lower cement leakage rate, however, with longer operation time, more fluoroscopy times, and higher cost. Further randomized controlled trials (RCTs) should be conducted to confirm these results.

Abstract Background Vertebral compression fracture is one of the most common complications of osteoporosis. In this study an unilateral curved vertebroplasty device was developed, and the safety, effectiveness, and surgical parameters of curved vertebroplasty (CVP) in the treatment of painful osteoporotic vertebral compression fractures was investigated and compared with traditional bipedicular vertebroplasty (BVP). Methods We investigated 104 vertebral augmentation procedures performed over 36 months. CVP and BVP procedures were compared for baseline clinical variables, pain relief (Visual Analog Scale, VAS), disability improvement (Oswestry Disability Index, ODI), operation time, number of fluoroscopic images, volume of cement per level, and cement leakage rate for each level treated. Complications and refracture incidence were also recorded in the two groups. Results The VAS and ODI in both group had no significant difference preoperative (P > 0.05), and a significant postoperative improvement in the VAS scores and ODI was found in both group (P < 0.001). However, the CVP group had significantly lower operation time, number of fluoroscopic images, and cement leakage rate per level than the BVP group (P < 0.05); however, the volumes of cement per level were similar in the two groups (P > 0.05). Neither group had any serious complications. Five and two patients in the BVP group developed refractures at non-adjacent and adjacent levels, respectively, with one patient developing refractures twice; however, none of the patients in the CVP group developed refractures at any level. Conclusions Our findings revealed that both CVP and BVP were safe and effective treatments for osteoporotic vertebral compression fractures, and CVP entails a shorter operation time, less exposure to fluoroscopy, and lower rate of cement leakage.

Radiographic Outcomes

Background: Osteoporotic vertebral compression fractures (VCFs) commonly occur in aged people. Balloon kyphoplasty (KP) has been proven to be efficacious for pain relief and reduction of vertebral height for patients with osteoporotic VCFs. However, very little is known about the comparison of clinical and radiographic outcomes between unilateral and bilateral balloon KP in treating this kind of patients. Objective: To compare the safety and long-term radiographic and clinical outcomes of unilateral or bilateral balloon KP to treat patients with osteoporotic VCFs. Study Design: A systemic review and meta-analysis of all randomized controlled trials (RCTs) comparing the analgesic efficacy, radiographic outcomes, and complications between unilateral and bilateral balloon KP in patients with osteoporotic VCFs. Setting: The MEDLINE, EMBASE, Pubmed, CINAHL databases, Bandolier, and the Cochrane Controlled Trials Register were systematically searched for evidence from their inception to July 2012 by 2 of the authors (J.L. and L.Z.). Methods: Relevant reports were reviewed by 2 assessors independently and the reference lists of retrieved papers were scrutinized to identify further studies for inclusion, using guidelines set by PRISMA statement criteria. Results: Three RCTs were enrolled in this study. The VAS scores showed no statistical difference between the groups before surgery and either at short-term or long-term follow-up. There was no statistical significance in polymethylmethacrylate (PMMA) leakage between the groups. Analysis of 2 studies showed statistical significance in surgery time (WMD -23.77 [-27.83, -19.71]; P < 0.00001) and PMMA (WMD -1.65 [-2.28, -1.02]; P < 0.00001) consumption between the groups. Limitations: There were few data sources from which to extract abstracted data or published studies. There were only 3 RCTs that met criteria enrollment in this meta-analysis. The quality of these trials was quite low (Jadad score: 1-2). Variable reporting of end points and inconsistent definitions meant that we were not able to include every study for each outcome. There was also clinical heterogeneity among the studies. Conclusion: The efficacy of both unilateral and bilateral balloon KP to provide rapid, significant, and sustained pain relief for patients with osteoporotic VCFs is validated. Unilateral balloon KP is a reasonable treatment for patients with osteoporotic VCFs considering that it could achieve equivalent pain relief with less surgery time and PMMA consumption compared to bilateral balloon KP. There was no evidence to prove that unilateral balloon KP results in higher incidence of PMMA leakage than bilateral balloon KP. Although unilateral balloon KP was less efficacious in the reduction of fractured vertebral body, it is still unclear if the clinical results of balloon KP were positively correlated with the restoration of vertebral height and amount.

Background: Previous studies have reported a high incidence of re-collapse of the augmented vertebrae after percutaneous vertebral augmentation (PVA) for osteoporotic vertebral compression fractures (OVCFs) with intravertebral vacuum cleft (IVC) during long-term followup. Previous IVC might be considered an important predisposing factor for re-collapse, but the prior studies could not find a significant correlation. Objective: To determine the incidence and distribution characteristics of IVCs and to further assess IVCs in their varied locations. To assess the long-term therapeutic efficacy of PVA for OVCFs with IVC. Study Design: A retrospective cohort study. Setting: Department of spinal surgery, an affiliated hospital of a medical university. Methods: A retrospective review was performed on 594 patients who underwent PVA to treat OVCFs from January 2010 to December 2013. Eighty-two patients with the IVC sign were enrolled in the study. The follow-up period was a minimum of 2 years. The difference between IVC and non-IVC patients was compared. Comparisons of the radiological and clinical findings at varied IVC locations were made pre-operatively and post-operatively (immediate, at one year, and at 2 years). Results: IVC incidence correlated with older patient age and severe demineralization. Other baseline parameters showed no significant differences. The rate of cement leakage and vertebral fracture was significantly lower in the IVC groups than in the non-IVC groups intraoperatively. There was no significant difference in the incidence of cement leakage or adjacent vertebral fractures between the 3 IVC groups. In the immediate postoperative period, all patients benefited from significant improvement in vertebral body height and kyphotic angle correction. However, significant re-collapse was observed at the 2-year post-operative followup for the IVC patients when compared to the non-IVC patients. Among the 3 IVC groups, the most severe re-collapse was observed with inferior endplate IVCs. Superior endplate IVCs and IVCs extending to both endplates demonstrated only mild re-collapse at the 2-year follow-up. Limitation: Due to the infrequency of this process, the number of patients with IVCs was small. Conclusion: PVA treatment was initially effective in all patients with OVCFs. However, significant re-collapse of the augmented vertebrae with IVCs, especially those with inferior endplate IVCs, was found with long-term follow-up.
