Comparative Study Meta-Analysis Review
BACKGROUND
High-viscosity cement (HVC) has been gradually applied in percutaneous vertebroplasty (PVP) and percutaneous kyphoplasty (PKP). Although HVC has been reported to reduce cement leakage, different opinions exist. To assess the complications of HVC in cement leakage in the treatment of vertebral compression fractures and to evaluate the clinical effect of HVC compared with low-viscosity cement (LVC).
METHODS
EMBASE, PubMed, Science Direct, Google Scholar and Cochrane Library databases were comprehensively searched from their inception to August 2017. Two researchers independently searched for articles and reviewed all retrieved studies. Forest plots were used to illustrate the results. The Q-test and I statistic were employed to evaluate between-study heterogeneity. Potential publication bias was assessed by funnel plot.
RESULTS
HVC reduced the occurrence of cement leakage (risk ratio (RR) = 0.38, 95% confidence interval (CI) = 0.29 to 0.51, P < 0.00001), especially in the disc space (RR = 0.45, 95% CI = 0.45 to 0.80, P = 0.007) and the vein (RR = 0.54, 95% CI = 0.35 to 0.85, P = 0.008) but not in the intraspinal space (RR = 0.48, 95% CI = 0.19 to 1.23, P = 0.13) or the paravertebral area (RR = 0.63, 95% CI = 0.32 to 1.22, P = 0.17). No significant differences in the visual analogue scale (VAS), Oswestry Disability Index (ODI), injected cement volume or adjacent vertebral fracture were noted between HVC and LVC (P > 0.05).
CONCLUSION
Compared with LVC, HVC results in a reduced incidence of cement leakage for the treatment of vertebral compression fractures, especially in the disc space and vein but not in the intraspinal space or the paravertebral area. In addition, HVC yields the same satisfactory clinical effect as LVC.

Meta-Analysis Review
BACKGROUND
Unilateral and bilateral percutaneous balloon kyphoplasty (PKP) are 2 main approaches for the treatment of patients with osteoporotic vertebral compression fractures (OVCFs). Numerous published systematic reviews and meta-analyses evaluating the effectiveness of 2 approaches remain inconclusive. In order to propose a significant principle to make decisions for comparing clinical safety and efficacy of unilateral versus bilateral PKP for treating OVCFs patients based on the currently best available evidence, a systematic review of overlapping meta-analysis was conducted.
METHODS
Three electronic databases, Pubmed/Medline, Embase2 and the Cochrance Library, were searched systematically to retrieve and identify all eligible systematic reviews and meta-analyses comparing unilateral and bilateral PKP for the treatment of patients with OVCFs. Only systematic reviews or meta-analyses with an exclusively pooled analysis of randomized controlled trials (RCTs) met the minimum eligibility criteria in this investigation. The Oxford Levels of Evidence, Jadad algorithm and Assessment of Multiple Systematic Reviews (AMSTAR) instrument were adopted for evaluation of the methodological quality for each included literature to select currently best available evidence.
RESULTS
Screening determined that out of 2159, 9 meta-analyses with level II or III of evidence met the inclusion criteria in the systematic review of overlapping meta-analyses. The multiple systematic reviews scores ranged from 8 to 9 with a mean of 8.55 (median 8.5). According to the search process and selection strategies of the Jadad algorithm, a meta-analysis by Feng et al with the best available evidence (12 RCTs and an AMSTAR score of 9) demonstrated that unilateral and bilateral PKP are both nice choices for the treatment of patients with OVCFs, and no significant differences were revealed in clinical scores, radiological outcomes, and quality of life with long-term follow-up. However, compared with bilateral PKP, unilateral PKP produced a shorter surgery time, smaller dosage of cement, lower risk of cement leakage, and relieved a higher degree of intractable pain at short-term follow-up after surgery.
CONCLUSION
Unilateral percutaneous balloon kyphoplasty is more advantageous and superior to bilateral percutaneous kyphoplasty, and should be considered an effective option for the treatment of patients with osteoporotic vertebral compression fractures.

BACKGROUND
Whether kyphoplasty or vertebroplasty is better for painful osteoporotic vertebral compression fracture is a widely debated issue. Studies on the comparison of the 2 approaches are relative limited and a wide variation exists in the patient population, study design, and results. These factors make it difficult for workers in this field to know the exact value of the 2 approaches.
OBJECTIVE
To perform a systematic review and meta-analysis to compare the clinical outcomes and complications of kyphoplasty versus vertebroplasty for painful osteoporotic vertebral compression fractures (OVCF).
STUDY DESIGN
A systematic review and meta-analysis.
METHODS
MEDLINE, EMBASE, and other databases were searched for all the relevant original articles published from January 1987 to September 2012 comparing kyphoplasty with vertebroplasty for painful OVCF. The following outcomes were mainly evaluated: visual analog scale (VAS), vertebral height, kyphosis angle, new vertebral fractures, and cement leakage.
RESULTS
A total of 15 articles fulfilled all the inclusion criteria. The baseline characteristics such as sex, age, and number of prevalent fractures were comparable for both groups (P > .05). VAS score for the kyphoplasty group was significantly more than that for the vertebroplasty group at 1-3 days, 3 months, 6 months, 1 year, and 2 years after surgery (P < .05). Vertebral height in the kyphoplasty group was significantly higher than the vertebroplasty group at 3 months, 6 months, and 2 years (P < 0.05). Kyphosis angle in the kyphoplasty group was significantly lower at 3 months, 6 months, and 2 years (P < 0.05). The occurrence of new vertebral fractures in the kyphoplasty group had no significant difference with the vertebroplasty group at 3 months, 6 months, and 2 years (P > 0.05). The occurrence of cement leakage was significantly lower in the vertebroplasty group (P < 0.05).
LIMITATIONS
The main limitations of this review are that the demographics and comorbidities of study participants were not reported. These possible sources of heterogeneity could not be examined.
CONCLUSIONS
Percutaneous kyphoplasty is better than vertebroplasty in the treatment of painful OVCF. Kyphoplasty had better improvement at VAS score, vertebral height, and kyphosis angle with lower occurrence of cement leakage.

Meta-Analysis
Efficacy of zoledronic acid with percutaneous kyphoplasty/vertebroplasty in the treatment of osteoporotic vertebral compression fractures: a systematic review and meta-analysis.
OBJECTIVE
The purpose of this study was to conduct a systematic review and meta-analysis analyzing the efficacy of zoledronic acid in improving outcomes with percutaneous vertebroplasty (PVP) and percutaneous kyphoplasty (PKP) surgeries for osteoporotic vertebral compression fracture (OVCF).
MATERIALS AND METHODS
We electronically searched the databases of PubMed, Embase, ScienceDirect, CENTRAL, and Google Scholar up to 15th September 2020. All types of studies assessing the use of zoledronic acid with PKP/PVP surgeries were included.
RESULTS
Seven studies were included. On meta-analysis of data from five studies reporting bone mineral density (BMD) as g/cm2, we found a statistically significant increase in BMD in the zoledronic group (MD: 0.14; 95% CI: 0.07, 0.21, I2=97%; p<0.001). On pooled analysis of two studies reporting T scores, a similar result in favour of the zoledronic acid group was noted (MD: 0.60; 95% CI: 0.23, 0.98, I2=76%; p=0.002). We also found a statistically significant reduction in pain scores (MD: -1.23; 95% CI: -1.59, -0.86, I2=97%; p<0.00001), ODI scores (MD: -9.54; 95% CI: -12.76, -6.31, I2=95%; p<0.00001) and serum type I procollagen peptide (CTX) levels (MD: -0.19; 95% CI: -0.25, -0.12, I2=98%; p<0.00001) with zoledronic acid as compared to control. Our analysis also found a significantly reduced risk of further vertebral fractures in patients receiving zoledronic acid as compared to control (RR: 0.17; 95% CI: 0.07, 0.39, I2=0%; p<0.00001).
CONCLUSIONS
Our review indicates that the use of once-yearly zoledronic acid in the peri-operative period of PVP/PKP procedures for patients with OVCF leads to significant improvement of BMD, reduced pain scores, better ODI scores, and reduced incidence of further vertebral fractures. Our results have clinical significance as it encourages the use of zoledronic acid for such patients for better clinical outcomes.

Therapeutic effect of kyphoplasty and balloon vertebroplasty on osteoporotic vertebral compression fracture: A systematic review and meta-analysis of randomized controlled trials.
INTRODUCTION
This study aimed to assess the treatment effects of kyphoplasty (KP) compared with percutaneous vertebroplasty (VP) in patients with osteoporotic vertebral compression fracture, based on evidence from randomized controlled trials (RCTs).
METHODS
The electronic databases PubMed (from 1966), EmBase (from 1974), and Cochrane Library (including Cochrane Central Register of Controlled Trials and Cochrane Reviews) were searched systematically to identify relevant studies published up to August 31, 2019. Meta-analyses were conducted for subjective pain as measured using visual analogue scale (VAS), disability function as measured by Oswestry disability index (ODI), and cement leakage. For VAS and ODI, mean change from the baseline and standard deviation were used; for cement leakage, numbers of events and patients in each group were used. The random-effects model was applied to summarize the effects across trials.
RESULTS
Previous reviews and meta-analysis included non-RCTs, which brought (for those studies) a higher risk of bias. Therefore, 6 RCTs involving 1077 patients were included in the meta-analysis. No between-group difference was found. The weighted mean difference was -0.19 (95% confidence interval [CI], -0.39-0.01; P = .057) for VAS and -3.51 (95% CI, -8.70-1.67; P = .184) for ODI. However, KP had numerically lower rates of cement leakage across trials in a consistent fashion (relative risk, 0.83; 95% CI, 0.74-0.94; P = .004).
CONCLUSIONS
Both KP and VP had clinically meaningful beneficial effects on pain and disability, and the effects were stable and similar. KP had significantly fewer cement leakages.

Review
BACKGROUND CONTEXT
Osteoporotic vertebral fractures (OVF) dramatically increase with age and are serious life altering adverse events for seniors resulting in increased rates of institutionalization, morbidity and mortality. Given the expanding population of the elderly and increasing prevalence of OVFs, cost-effective treatment strategies need to be considered. Percutaneous vertebral augmentation (VA) procedures such as vertebroplasty (VP) or balloon kyphoplasty (BK) are increasingly employed to treat painful vertebral fractures not responding to conservative management (CM) of bedrest and analgesia. Both VA procedures have been shown to be effective treatments for OVFs in multiple systematic reviews of randomized controlled trials. In this systematic review, analytical strategies, designs and results were compared for health economic studies evaluating cost-effectiveness of VA procedures, VP or BK for OVFs. Furthermore, assessments of quality (risk of bias) were conducted for the systematic review and the individual studies with peer-reviewed checklists recommended for cost-effectiveness studies.
PURPOSE
To provide an up-to-date systematic review of peer-reviewed studies evaluating cost-effectiveness of VA procedures, VP or KP for OVFs to support treatment and health care funding decisions.
STUDY DESIGN
This study is a systematic literature review and structured narrative synthesis.
STUDY SAMPLE
Peer reviewed health economic studies reporting cost-effectiveness for VA procedures, VP or BK for OVFs OUTCOME MEASURES: The following information extracted from the studies included: report country and year, study design, comparators, population, perspective, health valuations, costing sources and cost-effectiveness measures. For economic studies involving modeling, information was also extracted for model type, time horizon, key model drivers, and handling of uncertainty. Incremental cost-effectiveness ratio (ICER), the ratio of differences between comparator treatment groups in costs and health benefits, was considered the main cost-effectiveness measure.
METHODS
A systematic review was conducted of MEDLINE, EMBASE, CINAHL, ECONLIT, Cochrane Library and DARE databases up to the review date May 2021. Studies were reviewed for those reporting cost-effectiveness analyses on VA procedures including VP or BK for OVFs. Studies including only costs, abstracts, editorials, methodologies and reviews were not included. The selection of articles was reported in line with PRISMA guidance. A descriptive framework was developed to classify types of cost-effectiveness studies based on methodological differences and a structured narrative synthesis was used to summarize studies. Quality assessments were made with British Medical Journal checklist for individual cost-effectiveness studies and the CiCERO checklist for systematic reviews of cost-effectiveness studies.
RESULTS
In this systematic review, 520 references were identified through database searching and 501 were excluded as ineligible by titles and abstract based on prior eligibility criteria. From full-text reviews of 19 reports, ten were identified as eligible for the systematic review evaluating cost-effectiveness of VA procedures for OVFs. All references were published between 2008 and 2020. The ten cost-effectiveness studies, three for VP, three for BK and four for both VP and BK, all involved CM for OVFs as a treatment comparator. The studies involved different methods of economic analysis, modeling assumptions, cost and health valuations conducted in different health care setting over different time periods. A framework for the review outlines key features of cost-effectiveness study designs consisting of unmatched, matched, or randomized controls involving cost-effectiveness or cost-utility) analyses. Both VP and BK were cost-effective alternatives to CM for OVFs with earlier health gains and significantly shorter hospital stays. Cost-effectiveness estimates, ICERs, remained relatively stable and within willingness-to-pay thresholds under a range of sensitivity analyses. Comparisons between VP and BK were variable depending on modeling assumptions, but generally the procedures had similar health benefit gains with VP having lower acute procedural costs.
CONCLUSIONS
Both VP and BK, have been shown to be cost-effective alternatives to CM for osteoporotic vertebral fractures in diverse cost-effectiveness studies conducted in multiple health care settings. Trial-based cost-utility contributed the strongest evidence supporting cost-effectiveness determination for VP and BK for OVFs.

Review
BACKGROUND
Percutaneous vertebroplasty (PVP), percutaneous kyphoplasty (PKP), and bone-filling mesh containers(BFC) are three viable minimally invasive techniques that have been used to treat Kümmell's disease(KD). However, there is still debate as to which is safer and more effective. This study summarized the pros and cons of the three techniques in the treatment of KD through network meta-analysis(NMA).
METHODS
All eligible published clinical control studies comparing PVP, PKP, and BFC for KD up to December 2021 were collected by online search of Cochrane Library, PubMed, Embase, CNKI, Wanfang Database, and Chinese biomedical literature database. Data were extracted after screening, and Stata 16.0 software was used to perform the network meta-analysis.
RESULTS
Four randomized controlled trials (RCTs) and 16 retrospective case-control studies (CCTs) with a total of 1114 patients were included. The NMA results showed no statistical difference between the 3 procedures in terms of improving patients' clinical symptoms. PKP was most likely to be the most effective in correcting kyphosis, while BFC was likely to be the most effective in managing the occurrence of cement leakage. No statistical differences were found in the incidence of new vertebral fractures in adjacent segments.
CONCLUSIONS
Ranking analysis showed that BFC has the highest likelihood of being the optimal procedure for the treatment of KD, based on a combined assessment of effectiveness in improving patients' symptoms and safety in the occurrence of adverse events.

Journal of Neurointerventional Surgery Sep 2020Osteolytic lesions of the atlas (C1) are challenging to treat by vertebroplasty due to the vicinity of the vertebral artery and the spinal cord.
BACKGROUND
Osteolytic lesions of the atlas (C1) are challenging to treat by vertebroplasty due to the vicinity of the vertebral artery and the spinal cord.
OBJECTIVE
To present our experience with transoral vertebroplasty (TOV) for osteolytic lesions of the lateral mass of the atlas.
METHODS
Retrospective case series involving 15 consecutive patients (nine male, six female, mean age 63 years) who underwent TOV for the treatment of an osteolytic lesion of the lateral mass of the atlas. Among the osteolytic lesions, 10/15 (67%) were bone metastases from various cancers; 4/15 (27%) were lesions related to multiple myeloma; and one lesion (7%) was an aggressive hemangioma. All the TOVs were performed under general anesthesia and in most cases (10/15; 67%) in a hybrid angiosuite combining a C-arm flat panel and a CT scan. The remaining five patients were treated under biplane fluoroscopic guidance.
RESULTS
Vertebroplasty of the lateral mass of C1 through a transoral route was feasible in all cases. Significant pain relief was obtained in most cases (1 month average decrease in Numeric Rating Scale: 4.9±4.1). No major complication was recorded. In 7/15 cases (47%), cement leakage surrounding the C1 lateral mass was seen; none of these leakages had a significant clinical consequence. No additional spine surgery was required in any of the patients.
CONCLUSION
TOV of osteolytic lesions of the lateral mass of the atlas is feasible and seems safe and effective, providing pain relief and bone stabilization.

Review
Therapeutic vertebral cement augmentation for the treatment of painful skeletal diseases, although widely applied for more than several decades, still has not thoroughly resolve the problem of cement extravasation. Based on a review of literature published, the present study was to provide a systematic review of the current understanding of pulmonary cement embolism (PCE) associated with percutaneous vertebroplasty (PVP) or percutaneous kyphoplasty (PKP), and to summarize the incidence, clinical features, prophylaxis and therapeutic management of PCE after vertebral cement reinforcement. The reported incidence of PCE ranges widely, from 2.1% to 26%. Asymptomatic PCE is a common condition without permanent clinical sequelae. Nevertheless, it is emergent once a symptomatic PCE is presented. Close attention and effective pre-measures should be taken to avoid this catastrophic complication.

Review
STUDY DESIGN
Systematic review.
OBJECTIVES
To assess the efficacy of kyphoplasty in controlling pain and improving quality of life in oncologic patients with metastatic spinal disease and pathologic compression fractures of the spine.
METHODS
A literature search through medical database was conducted (using PubMed, EMBASE, Cochrane, and LILACS) for randomized controlled trials comparing balloon kyphoplasty versus the traditional treatment for compression fractures of the spine due to metastatic disease. Two investigators independently assessed all titles and abstracts to select potential articles to be included. Inclusion criteria consisted of randomized controlled trials involving patients with pathologic compression fractures due to spinal metastasis or multiple myeloma treated with balloon kyphoplasty procedure as one of the study interventions, while the control group was any other treatment modality. The risk of bias in individual studies was assessed.
RESULTS
Two studies, with a combined total of 181 patients, met inclusion criteria. Because of data heterogeneity, the meta-analysis was not possible, and individual analysis of studies was performed. There is moderate evidence that patients treated with balloon kyphoplasty displayed better scores for pain (Numeric Rating Scale), disability (Roland-Morris Disability Questionnaire), quality of life (Short Form-36 Health Survey), and functional status (Karnofsky Performance Status) compared with those undergoing the conventional treatment. Patients treated with kyphoplasty also have better recovery of vertebral height.
CONCLUSIONS
This study concluded that balloon kyphoplasty could be considered as an early treatment option for patients with symptomatic neoplastic spinal disease, although further randomized clinical trials should be performed for improvement of the quality of evidence.
