Efficacy of Recombinant Human Parathyroid Hormone versus Vertebral Augmentation Procedure on Patients with Acute Osteoporotic Vertebral Compression Fracture. Orthop Surg 2022; 14:2510-2518. [PMID: 36017765 PMCID: PMC9531108 DOI: 10.1111/os.13470] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/15/2022] [Revised: 07/25/2022] [Accepted: 07/26/2022] [Indexed: 11/28/2022] Open
Abstract
OBJECTIVE Although widely used in clinical practice, vertebral augmentation procedure (VAP) for osteoporotic vertebral compression fracture (OVCF) is not supported. Recently, the effect of recombinant human parathyroid hormone (1-34) (rhPTH) has been paid great attention for its efficacy in anti-osteoporosis and bone union. This study aims to explore the outcome of rhPTH on acute OVCF and compare it with VAP to clarify its therapeutic advantages. METHODS The retrospective study comprised 71 acute OVCF patients from January 2015 to March 2020: 22 received rhPTH treatment (rhPTH group) and 49 underwent VAP (VAP group). The rhPTH group was 15 women and seven men with an average of 76.18 years, and the VAP group were 35 women and 14 men with an average of 73.63 years. The thoracic/lumbar vertebrae were 14/8 in the rhPTH group and 29/20 in the VAP group. The average follow-up period was 14.05 months in the rhPTH group and 13.82 months in the VAP group. The two groups were assessed regarding the visual analog score (VAS), Oswestry Disability Index (ODI), OVCF bone union, bone mineral density (BMD), kyphotic angle (KA), anterior and posterior border height (ABH and PBH, respectively), adverse events and the health-related quality of life assessed by short form-36 health survey scores (SF-36). Categorical variables were analyzed by chi-square test and continuous variables between groups were analyzed by independent samples t-test or Mann-Whitney U test according to the normality. RESULTS During the follow-up, the VAS was significantly lower in the rhPTH group than in the VAP group at month 3 (0.39 ± 0.6 vs 0.68 ± 0.651) (p = 0.047), month 6 (0.45 ± 0.60 vs 2.18 ± 1.22) (p < 0.001), and month 12 (0.45 ± 0.60 vs 2.43 ± 1.49) (p < 0.001). At month 12, the ODI was significantly lower in the rhPTH group (18.59 ± 3.33%) than in the VAP group (28.93 ± 16.71%) (p < 0.001). Bone bridge was detected on sagittal computed tomography images of all fractured vertebrae in the rhPTH group. The BMD was significantly higher in the rhPTH group (87.66 ± 5.91 Hounsfield units [HU]) than in the VAP group (68.15 ± 11.32HU) (p < 0.001). There were no significant differences in the changes in KA, ABH, and PBH between groups (all p > 0.05). The incidence of new OVCF was significantly lower in the rhPTH group than in the VAP group (p = 0.042). All scores of SF-36 were significantly higher in the rhPTH group than in the VAP group (all p < 0.05). CONCLUSION In acute OVCF patients, rhPTH was better than VAP in increasing spinal BMD to promote OVCF healing, reduce new OVCF, and improve back pain, physical ability, and health-related quality of life.

Abstract
ABSTRACT Introduction: Vertebral fracture is the main complication of osteoporosis and is common among the elderly. Conservative treatment is the first choice for osteoporotic vertebral compression fractures (OVCF) but for persistent painful cases, percutaneous vertebral cement augmentation techniques, such as vertebroplasty and kyphoplasty, are indicated. We performed a systematic review to compare clinical and radiological outcomes of both methods. Methods: A systematic review was performed according to the PRISMA and Cochrane Handbook for Systematic Reviews of Interventions. The PICO search strategy consisted of the following terms: Population- Patients with OVCFs; Intervention- Kyphoplasty; Control- Vertebroplasty; Outcomes- Pain, Cement Leakage, Vertebral Body Height, Adjacent level fractures, Oswestry (ODI) and SF36. Results: Seven articles were included in the qualitative analysis, selecting only randomized controlled trials. Four hundred and fifty patients were treated with vertebroplasty (VP) and 469 with kyphoplasty (KP). The leakage rate of the VP group was 63% versus 14% for the KP group. However, these results were without statistical significance. The Visual Analogue Scale (VAS), ODI and SF-36 outcomes were evaluated based on the 6-month and 1-year follow-up results, and we were unable to find any significant differences between treatments. For restoration of vertebral height, the values of the KP group were, on average, 0.71 cm higher than those of the VP group, with 95% CI. Conclusion: Based on this systematic review, kyphoplasty is superior to vertebroplasty for achieving gains in vertebral body height. As regards cement leakage and other clinical outcomes, neither method showed statistically significant superiority. Level of Evidence I; Systematic review.

Abstract
BACKGROUND Despite optimal drug-conservative therapy, a relevant percentage of patients with vertebral compression fractures (WKF) do not experience any relevant improvement in their pain symptoms. Vertebroplasty (VP) and kyphoplasty (KP) are described in the literature as percutaneous interventional procedures for the treatment of WKF. OBJECTIVE Assessment of the effectiveness of the VP and KP in the treatment of WKF and discussion of the procedures in the context of the current literature. MATERIAL AND METHODS Presentation of the fundamentals of VP and KP and their further developments. Description of indications and contraindications. Discussion of the current literature and recommendations of the individual professional associations. RESULTS In patients with vertebral compression fractures, VP or KP of the affected vertebral body leads to a pain reduction in more than 90% of cases. Clinically relevant complications occur in less than 1% of interventions. CONCLUSION VP and KP are a safe and effective method for treating painful WKF. Optimal patient selection improves the clinical outcome.

Abstract
PURPOSE Osteoporotic vertebral compression fractures (OVCFs) are common in the elderly population and are often treated using percutaneous vertebroplasty (PVP). However, the effectiveness of PVP reported by various randomized controlled trials (RCTs) is inconclusive. This study aimed to analyze, from published literature, the efficacy and safety of PVP for OVCFs. METHODS A search was conducted in Medline, EMBASE, and Cochrane Libraries since their respective inception on January 1, 2019, for RCTs of OVCFs treated with PVP compared with non-operative treatment. The primary outcomes were pain relief at 1 to 2 weeks, 1 to 3 months, and 6 to 12 months. The secondary outcome was the rate of occurrence of new vertebral fractures. Meta-analysis was performed using a random effect model. RESULTS A total of 13 RCTs comprising 1624 patients were included. For the blinded studies, statistical differences were found between PVP and the sham injection group for the 3 primary outcomes in the subgroup of the Vertebroplasty for Acute Painful Osteoporotic fractURes (VAPOUR) trial. Although pain scores were similar between the PVP group and the sham injection group for the VAPOUR trial at each period, the effect size of PVP increased over time. For the open-label studies, PVP significantly reduced pain at all time points. The risk of new vertebral fractures was similar between the PVP groups and control groups. CONCLUSIONS Application of PVP was effective and safe only in patients with acute OVCFs having persistent and severe pain. No benefits were recorded, among patients with older fractures or those bearing non-severe symptoms.

Abstract
UNLABELLED The parameters extracted from quantitative computed tomography (QCT) images were used to predict vertebral strength through machine learning models, and the highly accurate prediction indicated that it may be a promising approach to assess fracture risk in clinics. INTRODUCTION Vertebral fracture is common in elderly populations. The main factor contributing to vertebral fracture is the reduced vertebral strength. This study aimed to predict vertebral strength based on clinical QCT images by using machine learning. METHODS Eighty subjects with QCT data of lumbar spine were randomly selected from the MrOS cohorts. L1 vertebral strengths were computed by QCT-based finite element analysis. A total of 58 features of each L1 vertebral body were extracted from QCT images, including grayscale distribution, grayscale values of 39 partitioned regions, BMDQCT, structural rigidity, axial rigidity, and BMDQCTAmin. Feature selection and dimensionality reduction were used to simplify the 58 features. General regression neural network and support vector regression models were developed to predict vertebral strength. Performance of prediction models was quantified by the mean squared error, the coefficient of determination, the mean bias, and the SD of bias. RESULTS The 58 parameters were simplified to five features (grayscale value of the 60% percentile, grayscale values of three specific partitioned regions, and BMDQCTAmin) and nine principal components (PCs). High accuracy was achieved by using the five features or the nine PCs to predict vertebral strength. CONCLUSIONS This study provided an effective approach to predict vertebral strength and showed that it may have great potential in clinical applications for noninvasive assessment of vertebral fracture risk.

Abstract
Vertebral augmentation is among the current standards of care to reduce pain in patients with vertebral fractures (VF), yet a lack of consensus regarding efficacy and safety of percutaneous vertebroplasty and kyphoplasty raises questions on what basis clinicians should choose one therapy over another. Given the lack of consensus in the field, the American Society for Bone and Mineral Research (ASBMR) leadership charged this Task Force to address key questions on the efficacy and safety of vertebral augmentation and other nonpharmacological approaches for the treatment of pain after VF. This report details the findings and recommendations of this Task Force. For patients with acutely painful VF, percutaneous vertebroplasty provides no demonstrable clinically significant benefit over placebo. Results did not differ according to duration of pain. There is also insufficient evidence to support kyphoplasty over nonsurgical management, percutaneous vertebroplasty, vertebral body stenting, or KIVA®. There is limited evidence to determine the risk of incident VF or serious adverse effects (AE) related to either percutaneous vertebroplasty or kyphoplasty. No recommendation can be made about harms, but they cannot be excluded. For patients with painful VF, it is unclear whether spinal bracing improves physical function, disability, or quality of life. Exercise may improve mobility and may reduce pain and fear of falling but does not reduce falls or fractures in individuals with VF. General and intervention-specific research recommendations stress the need to reduce study bias and address methodological flaws in study design and data collection. This includes the need for larger sample sizes, inclusion of a placebo control, more data on serious AE, and more research on nonpharmacologic interventions. Routine use of vertebral augmentation is not supported by current evidence. When it is offered, patients should be fully informed about the evidence. Anti-osteoporotic medications reduce the risk of subsequent vertebral fractures by 40-70%. © 2018 American Society for Bone and Mineral Research.

Abstract
Background To update vertebral augmentation literature by comparing outcomes between vertebroplasty (VP), balloon kyphoplasty (BKP), vertebral augmentation with implant (VAI), and nonsurgical management (NSM) for treating vertebral compression fractures (VCFs). Methods A PubMed literature search was conducted with keywords kyphoplasty, vertebroplasty, vertebral body stent, and vertebral augmentation AND implant for English-language articles from February 1, 2011, to November 22, 2016. Among the results, 25 met the inclusion criteria for the meta-analysis. Inclusion criteria were prospective comparative studies for mid-/lower-thoracic and lumbar VCFs enrolling at least 20 patients. Exclusion criteria included studies that were single arm, systematic reviews and meta-analyses, traumatic nonosteoporotic or cancer-related fractures, lack of clinical outcomes, or non-Level I and non-Level II studies. Standardized mean difference between baseline and end point for each outcome was calculated, and treatment groups were pooled using random effects meta-analysis. Results Visual analog scale pain reduction for BKP and VP was -4.05 and -3.88, respectively. VP was better than but not significantly different from NSM (-2.66), yet BKP showed significant improvement from both NSM and VAI (-2.77). The Oswestry Disability Index reduction for BKP showed a significant improvement over VAI (P < .001). There was no significant difference in changes between BKP and VP for anterior (P = .226) and posterior (P = .293) vertebral height restoration. There was no significant difference in subsequent fractures following BKP (32.7%; 95% confidence interval [CI]: 8.8%-56.6%) or VP (28.3%; 95% CI: 7.0%-49.7%) compared with NSM (15.9%; 95% CI: 5.2%-26.6%). Conclusions/Level of Evidence Based on Level I and II studies, BKP had significantly better and VP tended to have better pain reduction compared with NSM. BKP tended to have better height restoration than VP. Additionally, BKP had significant improvements in pain reduction and disability score as compared with VAI. Clinical Relevance This meta-analysis serves to further define and support the safety and efficacy of vertebral augmentation.

Abstract
The purpose of this study was to review and summarise the literature on appropriateness criteria for treatment of osteoporotic vertebral compression fractures (OVCF), with appropriateness defined as a treatment where the expected benefits outweigh the expected harms, confirmed by available evidence and expert opinion. A comprehensive search of peer-reviewed publications (PubMed, EMBASE) and grey literature was performed. To be included for analysis, documents had to be a review article (e.g. clinical guideline or meta-analysis), focus on OVCF and make a statement on treatment appropriateness. Eleven publications fulfilled the eligibility criteria. Among the five publications that made recommendations about non-surgical management (NSM), there is agreement that conservative methods are appropriate in OVCF patients who have low level of pain, and that the majority of patients should be treated with conservative methods before other treatments are initiated. All publications made recommendations about vertebral augmentation procedures (VAP), i.e. vertebroplasty (VP) and/or balloon kyphoplasty (BKP). VAP are mostly considered appropriate in patients with high level of pain who do not respond to NSM. However, results cannot be generalised due to heterogeneity of treatment recommendations and patient selection. Although there is a consensus that NSM should be considered as the first-line treatment, there is more heterogeneity in treatment recommendations for VAP. This could most likely be explained by an insufficient clinical evidence base for VAP and heterogeneity of OVCF patients, leading to greater reliance on expert opinion affecting the quality of evidence in the primary sources.

Abstract
The relative efficacy and harms of balloon kyphoplasty (BK) for treating vertebral compression fractures (VCF) are uncertain. We searched multiple electronic databases to March 2016 for randomized and quasi-randomized controlled trials comparing BK with control treatment (nonsurgical management [NSM], percutaneous vertebroplasty [PV], KIVA VCF treatment system [Benvenue Medical, Inc., Santa Clara, CA, USA], vertebral body stenting, or other) in adults with VCF. Outcomes included back pain, back disability, quality of life, new VCF, and adverse events (AEs). One reviewer extracted data, a second checked accuracy, and two rated risk of bias (ROB). Mean differences and 95% confidence intervals (CIs) were calculated using inverse-variance models. Risk ratios of new VCF and AE were calculated using Mantel-Haenszel models. Ten unique trials enrolled 1837 participants (age range, 61 to 76 years; 74% female), all rated as having high or uncertain ROB. Versus NSM, BK was associated with greater reductions in pain, back-related disability, and better quality of life (k = 1 trial) that appeared to lessen over time, but were less than minimally clinically important differences. Risk of new VCF at 3 and 12 months was not significantly different (k = 2 trials). Risk of any AE was increased at 1 month (RR = 1.73; 95% CI, 1.36 to 2.21). There were no significant differences between BK and PV in back pain, back disability, quality of life, risk of new VCF, or any AE (k = 1 to 3 trials). Limitations included lack of a BK versus sham comparison, availability of only one RCT of BK versus NSM, and lack of study blinding. Individuals with painful VCF experienced symptomatic improvement compared with baseline with all interventions. The clinical importance of the greater improvements with BK versus NSM is unclear, may be due to placebo effect, and may not counterbalance short-term AE risks. Outcomes appeared similar between BK and other surgical interventions. Well-conducted randomized trials comparing BK with sham would help resolve remaining uncertainty about the relative benefits and harms of BK. © 2017 American Society for Bone and Mineral Research.

Jelsma J, Maart S. Should additional domains be added to the EQ-5D health-related quality of life instrument for community-based studies? An analytical descriptive study. Popul Health Metr 2015; 13:13. [PMID: 26045697 PMCID: PMC4455977 DOI: 10.1186/s12963-015-0046-0] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2013] [Accepted: 05/22/2015] [Indexed: 11/30/2022] Open
Abstract
Background There is increasing interest in monitoring the health-related quality of life (HRQoL) of populations as opposed to clinical populations. The EQ-5D identifies five domains as being most able to capture the HRQoL construct. The question arises as to whether these domains are adequate within a community-based population or whether additional domains would add to the explanatory power of the instrument. Methods As part of a community-based survey, the responses of 310 informants who reported at least one problem in one domain filled in the EQ-5D three-level version and the WHOQOL-BREF (World Health Organization Quality of Life Scale – Abbreviated version). Using the EQ-5D visual analogue scale (VAS) of rating of health as a dependent variable, the five EQ-5D and four selected WHOQOL-BREF items were entered as dummy variables in multiple regression analysis. Results The additional domains increased the explanatory power of the model from 52 % (EQ-5D only) to 57 % (all domains). The coefficients of Self-Care and Usual Activities were not significant in any model. The most parsimonious model included the EQ-5D domains of Mobility, Pain/Discomfort, Anxiety/Depression, Concentration, and Sleep (adjusted r2 = .57). Conclusions The EQ-5D-3L performed well, but the addition of domains such as Concentration and Sleep increased the explanatory power. The user needs to weigh the advantage of using the EQ-5D, which allows for the calculation of a single summary index, against the use of a set of domains that are likely to be more responsive to differences in HRQoL within community living respondents. The poor predictive power of the Self-Care and Usual Activities domains within this context needs to be further examined.
