Background: Percutaneous vertebroplasty (PVP) and percutaneous balloon kyphoplasty (PKP) can increase bone strength as well as alleviate the pain caused by vertebral compression fractures (VCFs), and both procedures rely on polymethyl methacrylate (PMMA) cement injected into the fractured vertebra for mechanical stabilization of the VCFs. However, there is debate over which of these 2 surgical procedures can give better short-term and long-term outcomes. A lot of studies and meta-analysis were designed to assess the advantages and drawbacks of PKP and PVP in the treatment of VCFs, but most of them didn’t consider the effect of VCF levels on the treatment outcome, which can influence the results. Objective: To assess the safety and efficacy of PKP compared to PVP in the treatment of single level osteoporotic vertebral compression fractures (OVCF). Study Design: Studies with the following criteria were included: patients with VCFs due to osteoporosis; PKP comparing PVP; study design, RCT or prospective or retrospective comparative studies. Furthermore, the studies which reported at least one of the following outcomes: subjective pain perception, quality of life evaluation, incidence of new adjacent vertebral fracture, bone cement leakage, and post-operative kyphotic angle. Articles were excluded in our meta-analysis if they had a neoplastic etiology (i.e., metastasis or myeloma), infection, neural compression, traumatic fracture, neurological deficit, spinal stenosis, severe degenerative diseases of the spine, previous surgery at the involved vertebral body, and PKP or PVP with other invasive or semi-invasive intervention treatment. Setting: University hospital. Methods: A systematic search of all articles published through May 2014 was performed by Medline, EMASE, OVID, and other databases. All the articles that compared PKP with PVP on single level OVCF were identified. The evidence quality levels of the selected articles were evaluated by Grade system. Data about the clinical outcomes and complications were extracted and analyzed. Results: Eight studies, encompassing 845 patients, met the inclusion criteria. Overall, the results indicated that there were significant differences between the 2 groups in the short-term visual analog scale (VAS) scores, the long-term Oswestry Disability Index (ODI), short- and long-term kyphosis angle, the kyphosis angle improvement, the injected cement, and the cement leakage rates. However, there were no significant differences in the long-term VAS scores, the short-term ODI scores, the short- and long-term SF-36 scores, or the adjacent-level fracture rates. Limitations: Statistical efficacy can be improved by more studies, low evidence based non-RCT articles are likely to induce various types of bias, no accurate definition of short-term and long-term outcome time points. Conclusion: PKP and PVP are both safe and effective surgical procedures in treating OVCF. PKP has a similar long-term pain relief, function outcome (short-term ODI scores, short-and long-term SF-36 scores), and new adjacent VCFs in comparison to PVP. PKP is superior to PVP for the injected cement volume, the short-term pain relief, the improvement of short- and long-term kyphotic angle, and lower cement leakage rate. However, PKP has a longer operation time and higher material cost than PVP. To confirm this evaluation, a large multi-center randomized controlled trial (RCT) should be conducted.

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.

Background: Kyphoplasty has been proven to be an efficient method to relieve patient suffering from osteoporotic vertebral compression fractures (OVCFs). Because of its technological superiority, unilateral kyphoplasty consumes less operative time and bone cement than traditional bilateral kyphoplasty. However, there is controversy about which method is most efficient in the treatment of OVCFs. Thus, an overall analysis should be performed to shed light on the facts corroborating both procedures. Objective: To evaluate the safety and efficacy of unipedicular kyphoplasty versus bipedicular kyphoplasty in treating OVCFs. Study Design: Inclusion criteria were randomized controlled trials focusing on comparing unilateral versus bilateral balloon kyphoplasty in treatment of OVCFs. The exclusion criteria contained infection, neoplastic etiology, traumatic fracture, neural compression, neurological deficit, spinal stenosis, previous surgery at the involved vertebral body, long-term use of steroids, and kyphoplasty with other invasive or semi-invasive intervention treatment. Retrospective studies, reviews, technology introductions, and biochemical trials were also excluded. Settings: The PubMed MEDLINE, Cochrane Library, Web of Science, and EMBASE were systematic searched. Only randomized controlled trials published up to June 2015 comparing unilateral kyphoplasty with bilateral kyphoplasty in treatment of OVCFs were identified. Methods: Two researchers independently screeded the works for inclusion and data extraction. The Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system was used to assess the methodological quality and evidence synthesis. Results: Six articles with 563 patients were enrolled in this study. Results showed that the unilateral approach required less surgical time (MD, -23.19; 95% CI, [-27.08, -19.31]; P < 0.00001) and cement consumption (MD, -2.07; 95% CI, [-2.23, -1.91]; P < 0.00001), as well as a reduced cement leakage ratio (RR, 0.59; 95% CI, [0.35, 0.99]; P < 0.05) and improved short-term general health (MD, 1.48; 95% CI, [0.02, 2.93], P < 0.05). No significant difference was found in the visual analog scale score (short-term and long-term), Oswestry Disability Index score (mid-term and long-term) kyphotic angle reduction, restoration rate of anterior vertebral height, vertebral height loss rate, postoperative adjacent-level fractures, or in other assessments of 36-Item Short Form Health Survey parameters (short-term and long-term). Limitations: Only 6 studies were included, so that the sample size was still relatively small and publication bias could not be revealed in this study. Observation time of some data was inconsistent. All of these problems could influence the reliability of the results. Conclusion: Both unilateral kyphoplasty and bilateral kyphoplasty are safe and effective treatments for OVCFs. However, when operative time, cement volume, cement leakage, short-term general health, radiation dose, and hospitalization costs are taken into consideration, unilateral kyphoplasty may be the better choice. Yet, more high-quality RCTs with long-term follow-up are still required to make the final conclusion.

Abstract Background & Aim: Osteoporotic vertebral compression fractures (OVCFs) are acknowledged as common occurred fractures among humans, especially for the elderly population. The minimally invasive percutaneous methods such as kyphoplasty as well as vertebroplasty have been valid and effective tools in terms of reducing clinical problems, which are associated with more beneficial effects as compared to traditional methods such as open surgery or conservative treatment. Hence, we conducted the current meta-analysis in order to gather updated evidence available for the systematical assessment of the clinical and radiographic outcomes of VP in comparison of KP.Methods: Publications on comparison kyphoplasty versus vertebroplasty in treatment of OVCFs were collected. After rigorous and thorough review of quality, we extracted the data on the basis of eligible trials, which analyzed the summary hazard ratios (HRs) of the endpoints of interested.Results: Totally, our inclusion criteria involved five studies. 561subjects involving 334 patients received VP and 227 patients received KP were included, of which patients receiving KP or VP failed to show any significant differences in the visual analog scale (VAS) scores (MD =-0.02, 95% CI -0.40 – 0.35; P = 0.91),and the risk of cement leakage (OR =1.60, 95% CI 0.82 – 3.12; P = 0.17). Nevertheless, the Oswestry Disability Index (ODI) scores (MD =-1.56, 95% CI -2.39 – -0.73; P = 0.0002), the injected cement volume (MD =-0.40, 95% CI -0.77 – -0.04; P = 0.03) and the operation time (MD =-9.67, 95% CI -11.55 – -7.80; P ＜0.00001) in VP group were linked to markedly lower trend in comparison of KP group with significant statistical difference.Conclusion: The present meta-analysis controls the acceptable level of the efficacy across the involved trials. The VP had ODI scores, the injected cement volume and the operation time exerted several advantages in this meta-analysis. Yet, VP failed to show benefits in terms of the VAS scores and cement leakage in comparison of KP therapy. Given the combined results of our study, the optimal treatment for patient harboring OVCFs should be determined by further high-quality and multi-center RCTs along with longer follow-ups as well as larger sample size.

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 Percutaneous kyphoplasty (PKP) is a common treatment modality for painful osteoporotic vertebral compression fractures (OVCFs). Pre- and postoperative identification of risk factors for cement leakage and follow-up complications would therefore be helpful but has not been systematically investigated. Purpose To evaluate pre- and postoperative risk factors for the occurrence of short-term cement leakages and long-term complications after PKP for OVCFs. Material and Methods A total of 283 vertebrae with PKP in 239 patients were investigated. Possible risk factors causing cement leakage and complications during follow-up periods were retrospectively assessed using multivariate analysis. Cement leakage in general, three fundamental leakage types, and complications during follow-up period were directly identified through postoperative computed tomography (CT). Results Generally, the presence of cortical disruption ( P = 0.001), large volume of cement ( P = 0.012), and low bone mineral density (BMD) ( P = 0.002) were three strong predictors for cement leakage. While the presence of intravertebral cleft and Schmorl nodes ( P = 0.045 and 0.025, respectively) were respectively identified as additional risk factors for paravertebral and intradiscal subtype of cortical (C-type) leakages. In terms of follow-up complications, occurrence of cortical leakage was a strong risk factor both for new VCFs ( P = 0.043) and for recompression ( P = 0.004). Conclusion The presence of cortical disruption, large volume of cement, and low BMD of treated level are general but strong predictors for cement leakage. The presence of intravertebral cleft and Schmorl nodes are additional risk factors for cortical leakage. During follow-up, the occurrence of C-type leakage is a strong risk factor, for both new VCFs and recompression.

Abstract Background A systematic review and meta-analysis was performed to evaluate the short- and long-term effect of exercise therapy on physical function, independence and wellbeing in older patients following hip fracture, and secondly, whether the effect was modified by trial level characteristics such as intervention modality, duration and initiation timepoint. Methods Medline, CENTRAL, Embase, CINAHL and PEDro was searched up-to November 2020. Eligibility criteria was randomized controlled trials investigating the effect of exercise therapy on physical function, independence and wellbeing in older patients following hip fracture, initiated from time of surgery up-to 1-year. Results Forty-nine studies involving 3905 participants showed a small to moderate effect of exercise therapy at short term (end of intervention) on mobility (Standardized mean difference, SMD 0.49, 95%CI 0.22-0.76); Activities of Daily Living (ADL) (SMD 0.31, 95%CI 0.16-0.46); lower limb muscle strength (SMD 0.36, 95%CI 0.13-0.60); balance (SMD 0.34, 95%CI 0.14-0.54). At long term (closest to 1-year), small to moderate effects were found for mobility (SMD 0.74, 95%CI 0.15-1.34); ADL (SMD 0.42, 95%CI 0.23-0.61); balance (SMD 0.50, 95%CI 0.07-0.94) and Health related Quality of Life (HRQoL) (SMD 0.31, 95%CI 0.03-0.59). Certainty of evidence was evaluated using GRADE ranging from moderate to very low, due to study limitation and inconsistency. Conclusion We found low certainty of evidence for a moderate effect of exercise therapy on mobility in older patients following hip fracture at end-of-treatment and follow-up. Further, low evidence was found for small to moderate short-term effect on ADL, lower limb muscle strength and balance.

Objective: In year 2016, quick Sepsis-Related Organ Failure Assessment (qSOFA) was introduced as a better sepsis screening tool compared to systemic inflammatory response syndrome (SIRS). The purpose of this systematic review and meta-analysis is to evaluate the ability of the qSOFA in predicting short- and long-term mortality among patients outside the intensive care unit setting. Method: Studies reporting on the qSOFA and mortality from MEDLINE (published between 1946 and 15th December 2017) and SCOPUS (published before 15th December 2017). Hand-checking of the references of relevant articles was carried out. Studies were included if they involved inclusion of patients presenting to the ED; usage of Sepsis-3 definition with suspected infection; usage of qSOFA score for mortality prognostication; and written in English. Study details, patient demographics, qSOFA scores, short-term (<30 days) and long-term (≥30 days) mortality were extracted. Two reviewers conducted all reviews and data extraction independently. Results and Discussion: A total of 39 studies met the selection criteria for full text review and only 36 studies were inclided. Data on qSOFA scores and mortality rate were extracted from 36 studies from 15 countries. The pooled odds ratio was 5.5 and 4.7 for short-term and long-term mortality respectively. The overall pooled sensitivity and specificity for the qSOFA was 48% and 85% for short-term mortality and 32% and 92% for long-term mortality, respectively. Studies reporting on short-term mortality were heterogeneous (Tau=24%, I2=94%, P<0.001), while long-term mortality studies were homogenous (Tau=0%, I2<0.001, P=0.52). The factors contributing to heterogeneity may be wide age group, various clinical settings, variation in the timing of qSOFA scoring, and broad range of clinical diagnosis and criteria. There was no publication bias for short-term mortality analysis. Conclusion: qSOFA score showed a poor sensitivity but moderate specificity for both short and long-term mortality prediction in patients with suspected infection. qSOFA score may be a cost-effective tool for sepsis prognostication outside of the ICU setting.

Background: Many clinical trials have investigated the use of platelet-rich plasma (PRP) to treat rotator cuff–related abnormalities. Several meta-analyses have been published, but none have focused exclusively on level 1 randomized controlled trials. Purpose: To assess the efficacy of PRP for rotator cuff–related abnormalities and evaluate how specific tendon involvement, the inclusion of leukocytes, and the use of gel/nongel formulations affect pain and functional outcomes. Study Design: Systematic review and meta-analysis. Methods: The literature was screened following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Baseline, short-term, and long-term data were extracted for the Constant score, University of California, Los Angeles (UCLA) score, visual analog scale (VAS) for pain, retear rate, Simple Shoulder Test (SST), and American Shoulder and Elbow Surgeons (ASES) score. The 100-point modified Coleman Methodology Score (CMS) was used to assess methodological quality. Funnel plots and the Egger test were used to screen for publication bias, and sensitivity analysis was performed to evaluate the effect of potential outliers. Results: A total of 18 level 1 studies were included in this review, 17 (1116 patients) of which could be included in quantitative analysis. The mean modified CMS was 79.4 ± 10.39. The Constant scores of patients who received PRP were significantly better short term (weighted mean difference [WMD], 2.89 [95% CI, 0.89-4.90]; P < .01) and long term (WMD, 2.66 [95% CI, 1.13-4.19]; P < .01). The VAS scores were significantly improved short term (WMD, –0.45 [95% CI, –0.75 to −0.15]; P < .01). Sugaya grade IV and V retears in PRP-treated patients were significantly reduced long term (odds ratio [OR], 0.34 [95% CI, 0.20-0.57]; P < .01). In PRP-treated patients with multiple tendons torn, there were reduced odds of retears (OR, 0.28 [95% CI, 0.13-0.60]; P < .01). Patients who received leukocyte-rich PRP had significantly better Constant scores compared with the leukocyte-poor PRP group, but there was no difference in VAS scores. Patients receiving PRP gel reported higher Constant scores compared with the controls, whereas those receiving nongel PRP treatments did not, although there was no difference in VAS scores. Long-term odds of retears were decreased, regardless of leukocyte content (leukocyte-poor PRP: OR, 0.36 [95% CI, 0.16-0.82]; leukocyte-rich PRP: OR, 0.32 [95% CI, 0.16-0.65]; all P < .05) or usage of gel (nongel: OR, 0.42 [95% CI, 0.23-0.76]; gel: OR, 0.17 [95% CI, 0.05-0.51]; all P < .01). Conclusion: Long-term retear rates were significantly decreased in patients with rotator cuff–related abnormalities who received PRP. Significant improvements in PRP-treated patients were noted for multiple functional outcomes, but none reached their respective minimal clinically important differences. Overall, our results suggest that PRP may positively affect clinical outcomes, but limited data, study heterogeneity, and poor methodological quality hinder firm conclusions.
