Meta-Analysis
To identify the risk factors of the secondary fractures for osteoporotic vertebral compression fractures (OVCFs) after percutaneous vertebroplasty (PVP).We conducted a search of relevant articles using Cochrane Library, PubMed, Medline, Science Direct, Embase, the Web of Science and other databases. The time range we retrieved from establishment of the electronic database to November 2017. Gray studies were found in the references of included literature reports. STATA version 11.0 (Stata Corporation, College Station, Texas) was used to analyze the pooled data.Fourteen studies involving 1910 patients, 395 of whom had fracture secondary to the surgery were included in this meta-analysis. The result of meta-analyses showed the risk factors of the secondary fractures for OVCFs after PVP was related to bone mineral density (BMD) [95%CI (-0.650, -0.164), SMD=-0.407, P=.001], cement leakage ((RR=0.596, 95%CI (0.444,0.798), P = .001)), and kyphosis after primary operation ((SMD=0.741, 95%CI (0.449,1.032), P = .000)), but not to gender, age, body mass index, cement volume, thoracolumbar spine, and cement injection approaches.Bone mineral density, cement leakage, and kyphosis after primary operation are the risk factors closely correlative to the secondary fracture after PVP. There have not been enough evidences to support the association between the secondary fracture and gender, age, body mass index, cement volume, thoracolumbar spine, and cement injection approaches.

Meta-Analysis
Clinical efficacy of zoledronic acid combined with percutaneous kyphoplasty in the prevention and treatment of osteoporotic vertebral compression fracture: A systematic review and meta-analysis.
OBJECTIVE:
The aim of this study is to investigate the clinical efficacy of zoledronic acid (ZOL) in the treatment and prevention of osteoporotic vertebral compression fractures (OVCF) after percutaneous kyphoplasty (PKP) for elderly patients.
METHODS:
The PubMed, Cochrane Library, China National Knowledge Infrastructure (CNKI), Wanfang, VIP, and Embase were investigated through June 2020. All randomized controlled trials (RCT) involving ZOL injections for OVCF were enrolled. Outcome indicators included the bone mineral density (BMD), Visual Analog Scale (VAS), recompression vertebral fracture (RVF), Oswestry Disability Index (ODI), and bone metabolism (Procollagen type I N-terminal propeptide [PINP] and βcross-linked C-telopeptide of type I collagen [β-CTX]), bone cement leakage. Review Manager 5.3 was used to analyze these indicators.
RESULTS:
In this study, (1).. Eight studies had met the eligibility criteria, a total of 578 participants were involved (285 and 293 in the experimental (ZOL) group and control [no ZOL] group, respectively). (2).. The BMD scores of patients with OVCF in the experimental group were significantly higher than that in the control group ( < .05). The VAS scores were significantly different between the 2 groups at the 6, 12 months follow-up ( < .05). After PKP operation, ZOL injections reduced the rate of RVF ( < .05). In the comparison of ODI scores, the experimental group improved compared with the control group ( < .05). Respectively, the bone metabolism of patients with OVCF after ZOL was better than that of patients in control group ( < .05).
CONCLUSION:
Zoledronic acid had a significant effect on the treatment and prevention of OVCF in elderly osteoporotic patients after PKP. Due to the limited quality and data, more high-quality studies are needed to confirm the results of this meta-analysis.

Global Spine Journal Mar 2022Systematic review and meta-analysis.
STUDY DESIGN
Systematic review and meta-analysis.
OBJECTIVE
Percutaneous vertebroplasty (PVP) and percutaneous kyphoplasty (PKP) are minimally invasive techniques widely used for the treatment of neurologically intact osteoporotic Kümmell's disease (KD), but which treatment is preferable remains controversial. Therefore, this study aimed to shed light on this issue.
METHODS
Six databases were searched for all relevant studies based on the PRISMA guidelines. Two investigators independently conducted a quality assessment, extracted the data and performed all statistical analyses.
RESULTS
Eight studies encompassing 438 neurologically intact osteoporotic KD patients met the inclusion criteria. Compared to PVP, PKP was associated with greater improvement in the short- and long-term Cobb angle [SMD = -0.37, P = 0.007; SMD = -0.34, P = 0.012], short-term anterior vertebral height [SMD = 0.43, P = 0.003] and long-term middle vertebral height [SMD = 0.57, P = 0.012] and a lower cement leakage rate [SMD = 0.50, P = 0.003] but produced more consumption (cement injection volume, operative time, fluoroscopy times, intraoperative blood loss and operation cost). However, there were no differences between the 2 procedures in the short- and long-term VAS and ODI scores, long-term anterior vertebral height, overall complications or new vertebral fractures.
CONCLUSIONS
Both procedures are equally effective for neurologically intact KD in terms of the clinical outcomes, with the exception of a lower cement leakage risk and better radiographic improvement for PKP but greater resource consumption. Based on the evidence available, good clinical judgment should be exercised in the selection of patients for these procedures.

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.

Meta-Analysis
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.

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.

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.
