The prevalence of vertebral fracture amongst patients presenting with non-vertebral fractures

Proportion of Hidden Vertebral Fractures Among Egyptian Males With Fragility Hip Fractures in the Emergency Room of Ain Shams University Hospitals

Background Fragility fractures are linked to significant costs for society as well as significant pain and suffering, disability, and even death. It is well-recognized that osteoporosis-related fragility fractures raise the risk of subsequent fragility fractures. One of the most frequent osteoporotic fractures brought on by low bone mineral density and other risk factors is vertebral fractures. Considering that most vertebral fractures are asymptomatic and not clinically identified, proactive screening could stop additional impairment. Objective The current study aims to determine the prevalence and risk factors of hidden vertebral fractures in Egyptian males who have fragility hip fractures. Patients and methods A cross-sectional case-control study examining the correlation of risk factors between cases (fragility hip fracture and vertebral fractures) and a control group (fragility hip fracture without vertebral fracture) was carried out from September 2020 to September 2021 on patients visiting the orthopedic emergency department of a university hospital in Cairo, Egypt. Males who presented to the emergency room (ER) with fragility hip fractures and were 40 years of age or older met our inclusion criteria. For every patient who presented with a fragility hip fracture, standard lateral and anteroposterior radiographs of the dorso-lumbar spine were taken. Results A total of 43,935 patients visited the orthopedic emergency room (ER) throughout the study period; 13,034 of those patients were men, accounting for 29.7% of all orthopedic ER visits. Our inclusion criteria for fragility hip fractures were met by 132 male participants. The screening lumbosacral plain X-rays identified 27 (20.5%) of the 132 patients as having concomitant vertebral fractures in addition to the fragility hip fractures. Concomitant hidden vertebral fractures among Egyptian males with other fragility fractures, particularly fragility hip fractures, are predicted by the number of co-morbid diseases, hypertension, and continuous use of steroids and anti-epileptics. Conclusion Most fragility fractures are avoidable. Because one fragility fracture increases the likelihood of others, early detection is crucial. To prevent complications and mortality, it is important to identify and manage individuals who have a fragility hip fracture as they frequently have concurrent hidden vertebral fractures. Predictive risk factors for fragility vertebral fractures include hypertension, the number of concomitant illnesses, and chronic drugs (anti-epileptics and steroids).

Diagnosis and Management of Osteoporosis: A Comprehensive Review of Guidelines

Importance

Osteoporosis causes increased morbidity and mortality, and thus poses a significant economic burden to the health systems worldwide.

Objective

The aim of this study was to review and compare the most recently published major guidelines on diagnosis and management of this common medical entity.

Evidence Acquisition

A thorough comparative review of the most influential guidelines from the RACGP (Royal Australian College of General Practitioners), the ESCEO-IOF (European Society for Clinical and Economic Aspects of Osteoporosis-International Osteoporosis Foundation), the NOGG (National Osteoporosis Guideline Group), the NAMS (North American Menopause Society), the ES (Endocrine Society), and the ACOG (American College of Obstetricians and Gynecologists) was conducted.

Results

The reviewed guidelines generally agree on the definition, the criteria, and investigations used to diagnose osteoporosis. They also concur regarding the risk factors for osteoporosis and the suggested lifestyle modifications (calcium and vitamin D intake, normal body weight, reduction of alcohol consumption, and smoking cessation). However, there is lack of consensus on indications for fracture risk assessment in the general population and the exact indications for bone mineral density assessment. Referral to a bone specialist is reserved for complex cases of osteoporosis (NOGG, NAMS, and ACOG) or in case of inadequate access to care (RACGP). The use of hip protectors to reduce the risk of fractures is supported by RACGP, NOGG, and NAMS, solely for high-risk elderly patients in residential care settings. All guidelines reviewed recognize the efficacy of the pharmacologic agents (ie, bisphosphonates, denosumab, hormone therapy, and parathyroid hormone analogs). Nonetheless, recommendations regarding monitoring of pharmacotherapy differ, primarily in the case of bisphosphonates. The proposed intervals of repeat bone mineral density testing after initiation of drug therapy are set at 2 years (RACGP), 1-3 years (NAMS, ES, and ACOG), or 3-5 years (ESCEO-IOF and NOGG). All guidelines agree upon the restricted use of bone turnover markers only in bone specialist centers for treatment monitoring purposes. Finally, the definition of treatment failure varies among the reviewed guidelines.

Conclusions

Osteoporosis is a distressing condition for women, mainly those of postmenopausal age. Thus, it seems of paramount importance to develop consistent international practice protocols for more cost-effective diagnostic and management techniques, in order to improve women's quality of life.

Quality improvement initiative: implementing routine vertebral fracture assessments into an Australian Fracture Liaison Service

Osteoporosis is a global health concern and a major contributor to worldwide mortality rates. Vertebral fractures due to osteoporosis are common and often undetected. Since vertebral fractures are often missed, evidence and guidelines suggest that vertebral fracture assessment (VFA) may optimise current approaches to bone density tests. We aimed to integrate VFA into an Australian Fracture Liaison Service (FLS) and measure the impact it had on osteoporosis treatment initiation.A retrospective case note review was undertaken to determine the number of clinic patients receiving VFA before the change in practice. Proctor's seven domains of implementation strategy were used to facilitate quality improvement outcomes.The percentage of eligible patients receiving a routine VFA at the FLS imaging centre increased from 0% to 90%. The remaining 10% of patients did not receive a scan due to the patient not being able to assume the correct position, skilled staff being unavailable to perform the scan, or the patient declining. Post implementation, almost half (41%) of patients who underwent a VFA displayed abnormalities and 16 (4%) of these recorded a normal bone measure density score but abnormal VFA. Despite the successful adoption of the new screening protocol, there was no statistically significant increase in treatment initiation rates for patients with normal bone mass density scores.The FLS successfully integrated routine VFA into the osteoporosis care pathway. However, the introduction of VFA did not significantly increase treatment initiation. It may be more effective to offer VFAs to a proportion of patients based on a tailored approach rather than offering them routinely to all patients who access the FLS.

Effectiveness of fracture liaison services in osteoporosis

BACKGROUND

In response to the gradual decline in the number of prescriptions for anti-osteoporosis medication (AOM) following fragility fractures, fracture liaison services (FLSs) have been set up around the world with the aim of filling this treatment gap. Several studies have already reported the benefits of such organizations, particularly in reducing fracture risk, mortality rates and healthcare costs, and literature on FLSs has increased at a steady pace over time.

METHODS

A narrative review was conducted on the latest available findings on the effectiveness of FLSs. Various approaches to implementing an effective FLS program are discussed.

RESULTS

FLS programs have enhanced the management of osteoporosis-related fractures. However, several studies have highlighted that not all FLSs are necessarily effective in reducing subsequent fracture risk and mortality. Long-term AOM persistence and monitoring are another critical issue in FLS programs. A few studies have reported that FLSs are associated with an improvement in AOM persistence, regardless of the type of AOM. Practitioners in the FLS setting need to be aware of the impact of recency of fracture and fracture recurrence rates, and the need for timely interventions. The administration of zoledronic acid in an in-patient setting may improve AOM treatment rates in patients, who often encounter obstacles to outpatient follow-up. Introducing 'vertebral fracture identification services' in FLS programs is also an option. However, doing so leads to an increase in workload and this would need to be considered by any FLS that is considering introducing such a service. Evidence suggests that digital technologies can support (i) multidisciplinary teams in providing the best possible patient care based on current evidence, and (ii) patient self-management. However, as the methodological quality of many of the studies evaluating these technologies was poor, their validity of their results is limited.

CONCLUSION

Further research should focus on the optimal implementation of post-fracture care using automated systems, and standardized reporting of patient's characteristics and outcome measures using key performance indicators.

Vertebral fracture: epidemiology, impact and use of DXA vertebral fracture assessment in fracture liaison services

Vertebral fractures are independent risk factors for vertebral and nonvertebral fractures. Since vertebral fractures are often missed, the relatively new introduction of vertebral fracture assessment (VFA) for imaging of the lateral spine during DXA-measurement of the spine and hips may contribute to detect vertebral fractures. We advocate performing a VFA in all patients with a recent fracture visiting a fracture liaison service (FLS). Fracture liaison services (FLS) are important service models for delivering secondary fracture prevention for older adults presenting with a fragility fracture. While commonly age, clinical risk factors (including fracture site and number of prior fracture) and BMD play a crucial role in determining fracture risk and indications for treatment with antiosteoporosis medications, prevalent vertebral fractures usually remain undetected. However, vertebral fractures are important independent risk factors for future vertebral and nonvertebral fractures. A development of the DXA technology, vertebral fracture assessment (VFA), allows for assessment of the lateral spine during the regular DXA bone mineral density measurement of the lumbar spine and hips. Recent approaches to the stratification of antiosteoporosis medication type according to baseline fracture risk, and differences by age in the indication for treatment by prior fracture mean that additional information from VFA may influence initiation and type of treatment. Furthermore, knowledge of baseline vertebral fractures allows reliable definition of incident vertebral fracture events during treatment, which may modify the approach to therapy. In this manuscript, we will discuss the epidemiology and clinical significance of vertebral fractures, the different methods of detecting vertebral fractures, and the rationale for, and implications of, use of VFA routinely in FLS. • Vertebral fracture assessment is a tool available on modern DXA instruments and has proven ability to detect vertebral fractures, the majority of which occur without a fall and without the signs and symptoms of an acute fracture. • Most osteoporosis guidelines internationally suggest that treatment with antiosteoporosis medications should be considered for older individuals (e.g., 65 years +) with a recent low trauma fracture without the need for DXA. • Younger individuals postfracture may be risk-assessed on the basis of FRAX® probability including DXA and associated treatment thresholds. • Future fracture risk is markedly influenced by both site, number, severity, and recency of prior fracture; awareness of baseline vertebral fractures facilitates definition of true incident vertebral fracture events occurring during antiosteoporosis treatment. • Detection of previously clinically silent vertebral fractures, defining site of prior fracture, might alter treatment decisions in younger or older FLS patients, consistent with recent IOF-ESCEO guidance on baseline-risk-stratified therapy, and provides a reliable baseline from which to define new, potentially therapy-altering, vertebral fracture events.

Performance of HR-pQCT, DXA, and FRAX in the discrimination of asymptomatic vertebral fracture in postmenopausal Chinese women

Volumetric bone density (vBMD) and trabecular microarchitecture measured by high-resolution peripheral quantitative computed tomography (HR-pQCT) can discriminate the patients with high risk of asymptomatic vertebral fracture (VF) in postmenopausal Chinese women. These findings suggested that HR-pQCT could provide additional information on bone quality of the patients with asymptomatic VF.

INTRODUCTION

Although there were several studies using HR-pQCT to investigate asymptomatic VF, it remains uncertain if HR-pQCT parameters can discriminate asymptomatic VF patients, especially in Chinese population. The purpose of this study was to investigate whether bone quality measured by HR-pQCT could discriminate asymptomatic VF independent of hip areal bone mineral density (aBMD) measured by dual-energy x-ray absorptiometry (DXA) and fracture risks evaluated using built-in Fracture Risk Assessment Tool (FRAX_BMD).

METHODS

This is a nested case-control study. One hundred seventy-five ambulatory Chinese postmenopausal women aged 60-79 years were retrieved from Normative Reference Standards (NRS) cohort in Hong Kong. DXA was used to identify VF from lateral spine images (VFA) using Genant's semi-quantitative method. Major osteoporotic fracture risk was calculated using FRAX tool. HR-pQCT was used to assess vBMD, microarchitecture, and estimated strength at both distal radius and tibia. Comparison of HR-pQCT parameters between asymptomatic VF and control was performed using covariance analysis. Logistic regression analysis was performed for calculating the adjusted odds ratio (OR) with 95% confidence intervals (CI) of fracture status as per SD decrease in HR-pQCT parameters.

RESULTS

Women with asymptomatic VF were older than those of the control in our NRS cohort. Nevertheless, after adjusted for covariance, asymptomatic VF showed significantly lower trabecular vBMD (Tb.vBMD) at radius but higher SMI at tibia as compared with those of the control. Tb.vBMD at radius yielded the highest value of area under the curve (AUC) as compared with total hip aBMD and FRAX_BMD. However, no significant difference was found among each other.

CONCLUSION

Tb.vBMD at the radius and SMI at the tibia provided by HR-pQCT can discriminate asymptomatic VF independent of hip aBMD and FRAX_BMD by DXA in postmenopausal women.

Development of prediction model for osteoporotic vertebral compression fracture screening without using clinical risk factors, compared with FRAX and other previous models

This study developed a prediction model to assess the need for asymptomatic osteoporotic vertebral compression fracture (OVCF) screening in women without using clinical risk factors. Our results demonstrated that the combination of age, height loss, and femoral neck T-score can predict OVCF comparable to previous models, including FRAX.

PURPOSE

Osteoporotic vertebral compression fracture (OVCF) is a major fracture in osteoporosis patients. Early detection of OVCF can reduce the risk of subsequent fractures and death. Many existing diagnostic tools can screen for the risk of osteoporotic fracture but none aim to identify OVCF. The objective of this research is to study a predictive model for capturing OVCF and compare it with previous models.

METHODS

A retrospective review was conducted that included women aged ≥ 50 years who underwent dual-energy X-ray absorptiometry and vertebral fracture screening between 2012 and 2019. The data included age, height, weight, history of height loss (HHL), and bone mass density (BMD). Receiver operating characteristic analysis and univariate and multivariate logistic regression were performed. The predictive OVCF model was formulated, and the result was compared to other models.

RESULTS

A total of 617 women, a 179 of which had OVCFs, were eligible for analysis. Multivariate regression analysis showed age > 65, height loss > 1.5 cm, and femoral neck T-score < -1.7 as independent risk factors for OVCF. This model revealed comparable performance with FRAX. The model without BMD revealed superior performance to FRAX and other standard osteoporosis assessment models.

CONCLUSIONS

BMD and vertebral fracture screening should be eligible for individual women age > 65 years with an HHL more than 1.5 cm, regardless of BMD. Vertebral fracture assessment should be additionally conducted on these women with a femoral neck T-score less than -1.7.

Secondary hyperparathyroidism and thoracic vertebral fractures in heart failure middle-aged patients: a 3-year prospective study

PURPOSE

Vertebral fractures (VFs) were described in elderly patients with heart failure (HF) whereas their prevalence and determinants in younger HF patients are still unknown. This study aimed at assessing whether secondary hyperparathyroidism (SHPT) may influence the risk of VFs in middle-aged patients with HF.

METHODS

84 patients (44 males, median age 48.5 years, range 43-65) with HF were prospectively evaluated at the baseline and after 36-month follow-up for bone mineral density (BMD) and VFs by quantitative morphometry on chest X-rays. Serum PTH, calcium, 25-hydroxyvitamin D and 24-h-urinary calcium were evaluated at the baseline and every 6-12 months during the study period.

RESULTS

At baseline, SHPT, hypovitaminosis D and VFs were found in 43 patients (51.2%), 73 patients (86.9%) and 29 patients (34.5%), respectively. SHPT was associated with VFs at baseline [inverse probability-weighted (ipw) odds ratio (OR) 12.2, p < 0.001]. Patients were treated with vitamin D3 alone (56%), vitamin D3 plus calcium carbonate (21.4%), calcitriol alone (4.8%), bisphosphonates plus vitamin D3 (8.3%) or a combination of bisphosphonates, vitamin D3 and calcium carbonate (9.5%). At the end of follow-up, hypovitaminosis D was corrected in all patients, whereas 19/84 patients (22.6%) had persistent SHPT. During the follow-up, 16 patients developed incident VFs which resulted to be associated with baseline SHPT (ipw OR 55.7, p < 0.001), even after adjusting from BMD change from baseline to follow-up (ipw OR 46.4, p < 0.001).

CONCLUSIONS

This study provides a first evidence that SHPT may be a risk factor for VFs in middle-aged patients with HF.

Vertebral fracture assessment (VFA) in patients over 50 years of age with a non-severe peripheral fracture

The prevalence of unknown vertebral fractures evaluated by systematic vertebral fracture assessment (VFA) was 21% in patients over 50 years of age who suffered from a recent low-trauma non-severe peripheral fracture. The outcome of VFA resulted in changes in the management of osteoporosis.

INTRODUCTION

The aim of this study was to evaluate the utility of VFA in detecting vertebral fractures (VFs) in patients over 50 years of age, who suffered from a recent low-trauma non-severe peripheral fracture.

METHODS

This was an observational, single-center, cross-sectional study conducted in patients over 50 years of age, who presented a recent low-trauma non-severe peripheral fracture and were identified by the Fracture Liaison Service (FLS) of Amiens University Hospital between December 2017 and March 2019. VFA was interpreted by two trained rheumatologists providing a consensual reading using Genant semi-quantitative assessment.

RESULTS

Of the 359 eligible patients, 114 patients (31.8%) were included (mean age 65.6 ± 8.4 years; 89.5% female). Twenty-four patients (21%) had one or more VF diagnosed by VFA. The total number of VF diagnosed by VFA was 30: 20 VF (66.7%) grade 1, 7 VF (23.3%) grade 2, and 3 VF (10%) grade 3. Among the 24 patients with at least one prevalent VF diagnosed by VFA, 18 patients had an osteoporosis medication adaptation after the VFA results (16 osteoporosis medication initiation and 2 treatment intensification), and 6 patients would have had an osteoporosis medication even without the VFA results (66.7% versus 33.3% respectively, p < 0.001). Of the 51 patients receiving an osteoporosis medication after DXA and VFA, 18 patients (35.3%) had a change in the management of osteoporosis after knowing the outcome of VFA. All the VFs diagnosed by VFA were unknown before. We did not evidence any threshold (age, T-score, height loss) below which no VF was detected.

CONCLUSIONS

Our study demonstrates the usefulness of systematic VFA to detect prevalent VF in patients over 50 years of age who suffer from a recent non-severe peripheral fracture.

A patient-level key performance indicator set to measure the effectiveness of fracture liaison services and guide quality improvement: a position paper of the IOF Capture the Fracture Working Group, National Osteoporosis Foundation and Fragility Fracture Network

The International Osteoporosis Foundation (IOF) Capture the Fracture® Campaign with the Fragility Fracture Network (FFN) and National Osteoporosis Foundation (NOF) has developed eleven patient-level key performance indicators (KPIs) for fracture liaison services (FLSs) to guide quality improvement.

INTRODUCTION

Fracture Liaison Services (FLSs) are recommended worldwide to reduce fracture risk after a sentinel fracture. Given not every FLS is automatically effective, the IOF Capture the Fracture working group has developed and implemented the Best Practice Framework to assess the organisational components of an FLS. We have now developed a complimentary KPI set that extends this assessment of performance to the patient level.

METHODS

The Capture the Fracture working group in collaboration with the Fragility Fracture Network Secondary Fragility Fracture Special Interest Group and National Osteoporosis Foundation adapted existing metrics from the UK-based Fracture Liaison Service Database Audit to develop a patient-level KPI set for FLSs.

RESULTS

Eleven KPIs were selected. The proportion of patients: with non-spinal fractures; with spine fractures (detected clinically and radiologically); assessed for fracture risk within 12 weeks of sentinel fracture; having DXA assessment within 12 weeks of sentinel fracture; having falls risk assessment; recommended anti-osteoporosis medication; commenced of strength and balance exercise intervention within 16 weeks of sentinel fracture; monitored within 16 weeks of sentinel fracture; started anti-osteoporosis medication within 16 weeks of sentinel fracture; prescribed anti-osteoporosis medication 52 weeks after sentinel fracture. The final KPI measures data completeness for each of the other KPIs. For these indicators, levels of achievement were set at the < 50%, 50-80% and > 80% levels except for treatment recommendation where a level of 50% was used.

CONCLUSION

This KPI set compliments the existing Best Practice Framework to support FLSs to examine their own performance using patient-level data. By using this KPI set for local quality improvement cycles, FLSs will be able to efficiently realise the full potential of secondary fracture prevention and improved clinical outcomes for their local populations.

Osteoporosis in Polish Older Women: Risk Factors and Osteoporotic Fractures: A Cross-Sectional Study

Background: Osteoporosis is a skeletal disease. It is still not known which of the risk factors have the greatest impact on osteoporosis development. The study aimed to determine how the selected osteoporosis risk factors contribute to the development of the disease and to assess the risk of osteoporotic fractures in older women. Methods: A cohort of 99 older females was divided into two groups (with and without osteoporosis). The risk of osteoporosis was determined using assessment forms and bone densitometry data subjected to logistic regression. The risk of osteoporotic fractures was assessed by the FRAX tool (FRAX, Center for Metabolic Bone Diseases, University of Sheffield, UK). Results: The logistic regression analysis showed that the highest risk of developing osteoporosis associated with lifestyle, mainly cigarette smoking (odds ratio: OR = 2.12), past gynecological operations (OR = 1.46), corticosteroid therapies (OR = 1.38). More than half of participants were at a medium risk of femoral neck fractures (over 90% in the osteoporotic group). Conclusion: Most of the Polish women living in care facilities are at medium risk of low-energy fractures. Smoking appeared to have the strongest effect on osteoporosis among analyzed risk factors. The results may contribute to the creation of more appropriate prevention strategies.

Prevalence of asymptomatic radiographic vertebral fracture in postmenopausal Thai women

We aim to investigate the nationwide prevalence of asymptomatic radiographic vertebral fracture in Thailand. We found 29% of postmenopausal women had at least one radiographic vertebral fracture. The prevalence was significantly higher among women with osteoporosis at the total hip (TH) region which implies that TH bone mineral density is a determinant of vertebral fracture risk.

INTRODUCTION

Radiographic vertebral fracture is associated with an increased risk of osteoporotic fracture and mortality in postmenopausal women. We designed a study to determine the prevalence of asymptomatic vertebral fractures in postmenopausal Thai women.

METHODS

The study was designed as a cross-sectional investigation at five university hospitals so as to achieve representation of the four main regions of Thailand. Radiographs were taken from 1062 postmenopausal women averaging 60 years of age. The presence of vertebral fracture was assessed by the Genant's semiquantitative method with three independent radiologists. Respective bone mineral density was measured by dual-energy X-ray absorptiometry (DEXA) at the lumbar spine (LS), femoral neck (FN), and total hip (TH).

RESULTS

Among the 1062 women, 311 were found to have at least one radiographic vertebral fracture-yielding a prevalence of 29% (95% CI 23.6-32.0%)-and 90 (8.5%, 95% CI 6.8-10.2%) had at least two fractures. The prevalence of vertebral fracture increased with advancing age. Most fractures occurred at one vertebra (71%) and only 29% at multiple vertebrae. The prevalence of vertebral fracture was significantly higher among women with osteoporosis compared with non-osteoporosis at the TH region. There was no significant difference in the prevalence among women with or without osteoporosis at the LS or FN.

CONCLUSIONS

Radiographic vertebral fractures were common among Thai postmenopausal women (~ 29%). These findings suggest that approximately one in three postmenopausal women has undiagnosed vertebral fracture. Radiographic diagnosis should therefore be an essential investigation for identifying and confirming the presence of vertebral fractures.

The Effects of Home Exercise in Older Women With Vertebral Fractures: A Pilot Randomized Controlled Trial

BACKGROUND

Regular exercise is advocated in osteoporosis guidelines to prevent fractures. Few studies have evaluated the effect of exercise on functional performance, posture, and other outcomes that are important to patients after vertebral fractures.

OBJECTIVE

This pilot study will explore the effect of home exercise versus control on functional performance, posture, and patient-reported outcome measures.

DESIGN

This study was a parallel 2-arm pilot feasibility trial with 1:1 randomization to exercise or attentional control groups.

SETTING

This study took place in 5 Canadian and 2 Australian academic or community hospitals/centers.

PARTICIPANTS

This study included 141 women ≥65 years of age with radiographically confirmed vertebral fractures.

INTERVENTION

A physical therapist delivered exercise and behavioral counseling in 6 home visits over 8 months and monthly calls. Participants were to exercise ≥3 times weekly. Controls received equal attention.

MEASUREMENTS

Functional performance, posture, quality of life, pain, and behavior-change outcomes were assessed at baseline and after 6 (questionnaires only) and 12 months. Adherence to exercise was assessed by calendar diary. All t tests examined between-group mean differences (MD) in change from baseline in intention-to-treat and per-protocol analyses.

RESULTS

There was a small effect of exercise on 5 times sit-to-stand test versus control (MD = -1.58 [95% CI = -3.09 to -0.07], intention-to-treat; MD = -1.49 [95% CI = -3.12 to 0.16], per-protocol). There were no other major or statistically significant MDs for any other measured outcomes after follow-up. Adherence declined over time.

LIMITATIONS

Treatment effects on variables may have been underestimated due to multiple comparisons and underpowered analyses.

CONCLUSIONS

Our exploratory estimate of the effect of exercise on functional leg muscle strength was consistent in direction and magnitude with other trials in individuals with vertebral fractures. Declining adherence to home exercise suggests that strategies to enhance long-term adherence might be important in future confirmatory trials.

Frequency of Vertebral Fractures in Patients presenting with Hip Fractures

OBJECTIVE

To determine the frequency of vertebral fractures in patients presenting with hip fractures.

METHODS

This prospective study was conducted at The Indus Hospital, Karachi, from May 2018 to November 2018. All patients above 40 years presenting with hip fractures were enrolled and a dorsal lumbar lateral view radiograph was obtained to investigate for vertebral fractures. Data was entered and analyzed using SPSS. Post-stratification, Chi-square/Fisher exact test was applied as appropriate to assess the significant association. P value of ≤0.05 was considered significant.

RESULTS

Three hundred thirty five patients were enrolled. Of these, 189 (56.4%) were females and 165 (49.3%) presented with neck of femur fractures. Out of 335 hip fractures patients, 77 (23%) were found to have concomitant vertebral fractures, with 73 (96.1%) having a compression fracture. T12 was the most common vertebra involved and 68.8% of patients were asymptomatic. Co-morbid conditions were statistically significantly associated with vertebral fractures.

CONCLUSION

There is a high prevalence of asymptomatic vertebral fractures in our population, but low compared to studies from western countries. There is a need to evaluate these fractures separately for the prevention of morbidity and mortality.

The association between prevalent vertebral fractures and bone quality of the distal radius and distal tibia as measured with HR-pQCT in postmenopausal women with a recent non-vertebral fracture at the Fracture Liaison Service

We evaluated the association between prevalent vertebral fractures and bone micro-architecture and strength measured using HR-pQCT in postmenopausal women with a recent non-vertebral fracture visiting the Fracture Liaison Service. The presence and severity of prevalent vertebral fracture reflect generalized bone deterioration.

INTRODUCTION

We evaluated the association between prevalent vertebral fractures (VFs) and bone micro-architecture and strength measured using HR-pQCT in postmenopausal women visiting the Fracture Liaison Service.

METHODS

In this cross-sectional study in women aged 50-90 with a recent non-vertebral fracture (NVF), VFs were identified on lateral spine images by dual-energy X-ray absorptiometry. Bone micro-architecture and strength were measured at the non-dominant distal radius and distal tibia using HR-pQCT. Linear regression analyses were used to estimate the association between prevalent VFs and HR-pQCT parameters.

RESULTS

We included 338 women of whom 74 (21.9%) women had at least one prevalent VF. After adjustment for femoral neck aBMD (FN aBMD) and other parameters, women with at least one prevalent vertebral fracture had significantly lower total and trabecular vBMD and trabecular number (β - 16.7, - 11.8, and - 7.8 in the radius and - 21.4, - 16.6, and - 7.2 in the tibia, respectively), higher trabecular separation at the radius and tibia (β 9.0 and 9.3, respectively), and lower cortical thickness and calculated ultimate failure load and compressive bone strength at the tibia (β - 5.9, - 0.6, and - 10.9, respectively) as compared with those without prevalent VFs. Furthermore, more severe prevalent VFs were associated with even lower total and trabecular vBMD and lower ultimate failure load and compressive stiffness at the radius and tibia, and lower trabecular number and higher trabecular separation at the radius.

CONCLUSION

This study indicates that the presence and severity of prevalent VFs reflect generalized bone deterioration in women with a recent NVF, independently of FN aBMD.

Exercise for improving outcomes after osteoporotic vertebral fracture

BACKGROUND

Vertebral fractures are associated with increased morbidity (e.g. pain, reduced quality of life) and mortality. Therapeutic exercise is a non-pharmacological conservative treatment that is often recommended for patients with vertebral fractures to reduce pain and restore functional movement. This is an update of a Cochrane Review first published in 2013.

OBJECTIVES

To assess the effects (benefits and harms) of exercise intervention of four weeks or greater (alone or as part of a physical therapy intervention) versus non-exercise/non-active physical therapy intervention, no intervention or placebo among adults with a history of vertebral fractures on incident fragility fractures of the hip, vertebra or other sites. Our secondary objectives were to evaluate the effects of exercise on the following outcomes: falls, pain, physical performance, health-related quality of life (disease-specific and generic), and adverse events.

SEARCH METHODS

We searched the following databases until November 2017: the Cochrane Library (Issue 11 of 12), MEDLINE (from 2005), Embase (from 1988), CINAHL (Cumulative Index to Nursing and Allied Health Literature, from 1982), AMED (from 1985), and PEDro (Physiotherapy Evidence Database, from 1929). Ongoing/recently completed trials were identified by searching the World Health Organization International Clinical Trials Registry Platform and ClinicalTrials.gov. Conference proceedings were searched via ISI and SCOPUS, and targeted searches of proceedings of the American Congress of Rehabilitation Medicine and American Society for Bone and Mineral Research. Search terms or MeSH headings included terms such as vertebral fracture AND exercise OR physical therapy. For this update, the search results were limited from 2011 onward.

SELECTION CRITERIA

We included all randomized controlled trials and quasi-randomized trials comparing exercise or active physical therapy interventions with placebo/non-exercise/non-active physical therapy interventions or no intervention implemented in individuals with a history of vertebral fracture.

DATA COLLECTION AND ANALYSIS

Two review authors independently selected trials and extracted data using a pre-tested data extraction form. Disagreements were resolved by consensus, or third-party adjudication. We used Cochrane's tool for assessing risk of bias to evaluate each study. Studies were grouped according to duration of follow-up (i.e. a) 4-12 weeks; b) 16-24 weeks; c) 52 weeks); a study could be represented in more than one group depending on the number of follow-up assessments. For dichotomous data, we reported risk ratios (RR) and corresponding 95% confidence intervals (95% CI). For continuous data, we reported mean differences (MD) of the change from baseline and 95% CI. Data were pooled for Timed Up and Go test, self-reported physical function measured by the QUALEFFO-41 physical function subscale score (scale of zero to 100; lower scores indicate better self-reported physical function), and disease-specific quality of life measured by the QUALEFFO-41 total score (scale of zero to 100; lower scores indicate better quality of life) at 12 weeks using a fixed-effect model.

MAIN RESULTS

Nine trials (n = 749, 68 male participants; two new trials in this review update) were included. Substantial variability across the trials prevented any meaningful pooling of data for most outcomes. Risk of bias across all studies was variable; low risk across most domains in four studies, and unclear/high risk in most domains for five studies. Performance bias and blinding of subjective outcome assessment were almost all high risk of bias.One trial reported no between-group difference in favor of the effect of exercise on incident fragility fractures after 52 weeks (RR 0.54, 95% CI 0.17 to 1.71; very low-quality evidence with control: 184 per 1000 and exercise: 100 per 1000, 95% CI 31 to 315; absolute difference: 8%, 95% CI 2 to 30). One trial reported no between-group difference in favor of the effect of exercise on incident falls after 52 weeks (RR 1.06, 95% CI 0.53 to 2.10; very low-quality evidence with control: 262 per 1000 and exercise: 277 per 1000; 95% CI 139 to 550; absolute difference: 2%, 95% CI -12 to 29). These findings should be interpreted with caution because of the very serious risk of bias in these studies and the small sample sizes resulting in imprecise estimates.We are uncertain that exercise could improve pain, self-reported physical function, and disease-specific quality of life, because certain studies showed no evidence of clinically important differences for these outcomes. Pooled analyses revealed a small between-group difference in favor of exercise for Timed Up and Go (MD -1.13 seconds, 95% CI -1.85 to -0.42; studies = 2), which did not change following a sensitivity analysis (MD -1.09 seconds, 95% CI -1.78 to -0.40; studies = 3; moderate-quality evidence). Exercise improved QUALEFFO-41 physical function score (MD -2.84 points, 95% CI -5.57 to -0.11; studies = 2; very low-quality evidence) and QUALEFFO-41 total score (MD -3.24 points, 95% CI -6.05 to -0.43; studies = 2; very low-quality evidence), yet it is unlikely that we observed any clinically important differences. Three trials reported four adverse events related to the exercise intervention (costal cartilage fracture, rib fracture, knee pain, irritation to tape, very low-quality evidence).

AUTHORS' CONCLUSIONS

In conclusion, we do not have sufficient evidence to determine the effects of exercise on incident fractures, falls or adverse events. Our updated review found moderate-quality evidence that exercise probably improves physical performance, specifically Timed Up and Go test, in individuals with vertebral fracture (downgraded due to study limitations). However, a one-second improvement in Timed Up and Go is not a clinically important improvement. Although individual trials did report benefits for some pain and disease-specific quality of life outcomes, the findings do not represent clinically meaningful improvements and should be interpreted with caution given the very low-quality evidence due to inconsistent findings, study limitations and imprecise estimates. The small number of trials and variability across trials limited our ability to pool outcomes or make conclusions. Evidence regarding the effects of exercise after vertebral fracture in men is scarce. A high-quality randomized trial is needed to inform safety and effectiveness of exercise to lower incidence of fracture and falls and to improve patient-centered outcomes (pain, function) for individuals with vertebral fractures (minimal sample size required is approximately 2500 untreated participants or 4400 participants if taking anti-osteoporosis therapy).

Fracture liaison programs

In view of the high imminent risk of having subsequent fractures after a fracture, early evaluation and treatment decisions to prevent subsequent fractures are advocated. After a hip fracture, the fracture liaison service (FLS) and orthogeriatric care are considered the most appropriate organisational approaches for secondary fracture prevention following a recent fracture. Their introduction and implementation have been shown to increase evaluation and treatment of patients at high risk for subsequent fracture. Of real-world cohort studies, most, but not all studies, indicate a lower incidence of fracture and longer survival after treatment with nitrogen-containing bisphosphonates.

Vertebral Fractures among Patients Referred for Bone Densitometry Screening in Dubai Primary Health Care Facilities

Vertebral fractures are one of the most common fractures associated with low bone mineral density. However two-thirds to three-fourths of patients with vertebral fractures are not clinically recognized. The objective of this study was to determine the prevalence of vertebral fractures in patients referred for bone densitometry and the most common site of fracture. The study was carried out in the osteoporosis clinic in Dubai primary health care center. A total of 120 patients were examined using the dual energy X-ray absorptiometry. Of all the patients, 48.3% were osteoporotic and 40.9% were osteopenic. The overall prevalence of vertebral fracture was 14.2%. The result showed that the prevalence of vertebral fracture was higher in female compared to male (15.7% and 9.7%, respectively). It was found that patients aged 80 and above had the highest prevalence of vertebral fracture (54.5%). Undiagnosed vertebral fractures were common. Therefore, it is crucial to prevent vertebral fracture through early diagnosis and appropriate treatment of osteoporosis.

Exploring the association between number, severity, location of fracture, and occiput-to-wall distance

This study of women with a suspected vertebral fracture determined the association between vertebral fracture characteristics and posture. The number of fractures was associated with posture. Severity of fracture was associated with posture when adjusting for pain. Fracture characteristics explain some variability in posture in women with a suspected vertebral fracture.

PURPOSE

Osteoporotic vertebral fractures are associated with increased morbidity and mortality. An accumulation of vertebral fractures may lead to forward head posture, which has been independently associated with mortality. It is unclear how fracture characteristics, including the number, severity, and location of fracture, contribute to occiput-to-wall distance (OWD).

METHODS

This was a cross-sectional secondary data analysis using baseline data from a randomized controlled trial, in community-dwelling women aged 65 years and older with a suspected vertebral fragility fracture. Lateral thoracic and lumbar spine radiographs were used to determine the number, location, and severity of fracture. Occiput-to-wall distance (OWD) was used to assess forward head posture. Pain during movement (0-10 scale) and age were considered as confounding variables. Multivariable regression models were used to evaluate relationships between fracture variables and OWD.

RESULTS

Participants (n = 158) were of mean age 75.9 (SD 6.5) years with a mean (SD) BMI = 26.7 (5.3) kg/m², OWD = 5.7 (4.6) cm, and number of fractures = 2.4 (2.4). In unadjusted analyses, the number of fractures (B = 0.82, 95% CI = 0.04, 1.59) was associated with OWD. When adjusting for pain, severity of fractures (B = 1.08, 95% CI = 0.001, 2.15) was independently associated with OWD. Location was not associated with OWD in any of the models.

CONCLUSIONS

The number of fractures was significantly associated with OWD in the unadjusted model, explaining more of the variability in OWD than other fracture characteristics. Severity of fracture was associated with OWD in the adjusted model. However, pain may confound the relationship between OWD and fracture characteristics.

High Prevalence of Radiological Vertebral Fractures in Patients With TSH-Secreting Pituitary Adenoma

Background

Bone loss and high risk of fractures have been reported in patients with primary hyperthyroidism, whereas data on skeletal health in TSH-secreting adenoma (TSH-oma) are scant, and the risk of fractures in this specific clinical context has not been investigated so far. In this cross-sectional study, we aimed at evaluating for the first time, to our knowledge, the prevalence and determinants of radiological vertebral fractures (VFs) in patients with TSH-oma.

Methods

Twenty-two patients (10 males, 12 females; median age 47 years) with TSH-oma and 44 patients (20 males, 24 females; median age 49 years) with nonfunctioning pituitary adenoma (NFPA) were retrospectively evaluated for thoracic VFs using a morphometric approach on lateral chest X-ray routinely performed in the presurgical diagnostic workup.

Results

The prevalence of VFs was significantly higher in TSH-oma vs NFPA (59.1% vs 22.7%; P = 0.003), the difference being still significant (odds ratio, 10.5; P = 0.005) after correction for the size of pituitary adenomas and biochemical parameters. In TSH-oma, the prevalence of VFs was significantly associated with older age (P = 0.007) and higher serum free T4 values (P = 0.02). In 20 patients, data on presurgical medical therapies of TSH-oma were available. All patients not treated with somatostatin receptor ligands were fractured compared with 25% of those who were treated with these drugs (P = 0.001). No significant (P = 0.25) association between VFs and treatment with methimazole was found.

Conclusions

This study provides the first evidence, to our knowledge, that patients with TSH-oma may develop VFs in close relationship with severity of hyperthyroidism.

Vertebral fracture assessment in patients presenting with a non-hip non-vertebral fragility fracture: experience of a UK Fracture Liaison Service

Twenty-five percent of patients with a non-hip non-vertebral fragility fracture have an undiagnosed vertebral fracture detected by vertebral fracture assessment during bone densitometric assessment. The prevalence of an undiagnosed vertebral fracture is higher in older people, and they are more likely to have multiple vertebral fractures.

PURPOSE

Most vertebral fragility fractures (VFF) have no history of trauma. Vertebral fracture assessment (VFA) during dual energy x-ray absorptiometry (DXA) can be used to detect these VFFs. This study aims to identify the prevalence of undiagnosed VFF in patients presenting with a non-hip non-vertebral fragility fracture.

METHODS

Patients identified by the fracture liaison service (FLS) of a large UK university hospital presenting with a non-hip non-vertebral fragility fracture were evaluated from 1 January 2012 to 30 September 2015. Local protocol identified those that would proceed for VFA. Data was collected on patient characteristics, fracture details, bone mineral density (BMD) measurements and VFA results.

RESULTS

Five hundred sixty-seven patients (mean (SD) age, 72 (9.4) years) of mostly women (88.3%) had a VFA performed as part of their DXA assessment. One hundred forty-three patients (25.2%) were identified to have a vertebral fracture, of whom 57.3% of them had one fracture. 49.5% of those with vertebral fractures had BMD measurements diagnostic of osteoporosis. Mean (SD) age was higher in those with vertebral fractures compared to those without; 74.9 (8.3) years vs 70.4 (9.5) years, p < 0.00. Those aged 75 years and over were more likely to have multiple fractures than those younger than 75 years (16.3 vs 4%, p = 0.01).

CONCLUSION

A quarter of patients presenting with a non-hip non-vertebral fragility fracture have an undiagnosed vertebral fracture. Older people are more likely to have vertebral fractures and more likely to have multiple fractures. VFA during bone densitometric assessment can further aid stratifying future fracture risk.

UK clinical guideline for the prevention and treatment of osteoporosis

INTRODUCTION

In 2008, the UK National Osteoporosis Guideline Group (NOGG) produced a guideline on the prevention and treatment of osteoporosis, with an update in 2013. This paper presents a major update of the guideline, the scope of which is to review the assessment and management of osteoporosis and the prevention of fragility fractures in postmenopausal women and men age 50 years or over.

METHODS

Where available, systematic reviews, meta-analyses and randomised controlled trials were used to provide the evidence base. Conclusions and recommendations were systematically graded according to the strength of the available evidence.

RESULTS

Review of the evidence and recommendations are provided for the diagnosis of osteoporosis, fracture-risk assessment, lifestyle measures and pharmacological interventions, duration and monitoring of bisphosphonate therapy, glucocorticoid-induced osteoporosis, osteoporosis in men, postfracture care and intervention thresholds.

CONCLUSION

The guideline, which has received accreditation from the National Institute of Health and Care Excellence (NICE), provides a comprehensive overview of the assessment and management of osteoporosis for all healthcare professionals who are involved in its management.

Effect of implementation of guidelines on assessment and diagnosis of vertebral fractures in patients older than 50 years with a recent non-vertebral fracture

We evaluated the impact of a new Dutch guideline on systematic implementation of densitometric Vertebral Fracture Assessment (VFA) in patients with a recent non-vertebral fracture. Systematic implementation resulted in a significant increase of VFA, diagnosis of vertebral fractures (VFs), and percentage of patients eligible for treatment.

INTRODUCTION

VFs are underdiagnosed although they are important predictors of fracture risk, independent of age and bone mineral density (BMD). The Dutch guideline on osteoporosis and fracture prevention recommends VFA in all patients aged >50 years with a recent non-VF. Our aim was to evaluate the effect of systematic implementation of densitometric VFA in patients with a recent non-VF at the fracture liaison service (FLS).

METHODS

VFA was performed on lateral images of the spine using dual-energy X-ray absorptiometry (DXA) and graded according to Genant using Spine Analyzer software.

RESULTS

We evaluated 582 patients before and 484 after implementation (mean age 67 and 66 years; 71 and 74% women, respectively). Performing VFA increased from 4.6 to 97.1% (p < 0.001) and the diagnosis of VFs from 2.2 to 26.2% for grade ≥ 1 (p < 0.001) and from 0.9 to 14.7% for grade ≥ 2 (p < 0.001). Prevalence of VFs increased with age (5.2% in 50-59-year olds to 27.8% in 80+-year olds, p < 0.001), but was similar for both genders, non-VF locations, and BMD. Including patients with osteopenia and a VF increased the percentage of patients eligible for treatment by a quarter, from 31.0% in the pre-guideline to 38.4% in the post-guideline cohort.

CONCLUSIONS

Systematic guideline implementation resulted in a significant increase of VFA, diagnosis of VFs, and percentage of patients eligible for treatment. VFA contributes to documenting the high prevalence of VFs in patients visiting the FLS with a non-VF in both genders, at any age, non-VF location, and BMD.

The Phenotype of Patients with a Recent Fracture: A Literature Survey of the Fracture Liaison Service

The aetiology of fractures in patients aged 50 years and older is multifactorial, and includes bone- and fall-related risks. The Fracture Liaison Service (FLS) is recommended to identify patients with a recent fracture and to evaluate their subsequent fracture risk, in order to take measures to decrease the risk of subsequent fractures in patients with a high risk phenotype. A literature survey was conducted to describe components of the bone- and fall-related phenotype of patients attending the FLS. Components of the patient phenotype at the FLS have been reported in 33 studies. Patient selection varied widely in terms of patient identification, selection, and FLS attendance. Consequently, there was a high variability in FLS patient characteristics, such as mean age (64-80 years), proportion of men (13-30%), and fracture locations (2-51% hip, <1-41% vertebral, and 49-95% non-hip, non-vertebral fractures). The studies also varied in the risk evaluation performed. When reported, there was a highly variability in the percentage of patients with osteoporosis (12-54%), prevalent vertebral fractures (20-57%), newly diagnosed contributors to secondary osteoporosis and metabolic bone disorders (3-70%), and fall-related risk factors (60-84%). In FLS literature, we found a high variability in patient selection and risk evaluation, resulting in a highly variable phenotype. In order to specify the bone- and fall related phenotypes at the FLS, systematic studies on the presence and combinations of these risks are needed.

Adjusting FRAX® on TBS for identification of subjects at high risk of fractures

The objective of this study was to compare the proportion of patients at high fracture risk according to FRAX® and FRAX® adjusted on TBS in patients hospitalized for a non vertebral fractures. Patients were selected from a Fracture Liaison Service FLS): clinical risk factors, bone mineral density (BMD) and TBS were assessed at the time of the fracture. Without considering the current fracture, we calculated FRAX® and FRAX® adjusted on TBS (TBS-FRAX®), and compared the proportion of patients with a high risk for major osteoporotic fracture (MOF)>20% according to FRAX® and TBS-FRAX®, and the proportion of subjects who should be treated according to current guidelines. Four hundred and thirteen patients were included for a non vertebral fracture (84.5% women, mean age of 73.9±11.7years), Two hundred and eight patients (50.4%) had osteoporosis (T≤-2.5 at least one site) and the mean value of TBS was 1.206 (±0.111). The proportion of patients with a risk of MOF≥20% before the fracture was similar with FRAX® and TBS-FRAX® (24.7% vs 25.4%). The proportion of patients identified with a risk of MOF above the threshold value of therapeutic intervention was higher using TBS-FRAX® than FRAX® for the age categories of 60-70years (38.3% vs 30.9%, p=0.01) and 70-80years (31.2% vs. 26.6%, p=0.04). This study showed that the proportion of patients at high risk of fracture is similar using FRAX® and FRAX® adjusted on TBS in patients hospitalized for a non vertebral fracture in a FLS.

Spine fracture prevalence in a nationally representative sample of US women and men aged ≥40 years: results from the National Health and Nutrition Examination Survey (NHANES) 2013-2014

Spine fracture prevalence is similar in men and women, increasing from <5 % in those <60 to 11 % in those 70-79 and 18 % in those ≥80 years. Prevalence was higher with age, lower bone mineral density (BMD), and in those meeting criteria for spine imaging. Most subjects with spine fractures were unaware of them.

INTRODUCTION

Spine fractures have substantial medical significance but are seldom recognized. This study collected contemporary nationally representative spine fracture prevalence data.

METHODS

Cross-sectional analysis of 3330 US adults aged ≥40 years participating in NHANES 2013-2014 with evaluable Vertebral Fracture Assessment (VFA). VFA was graded by semiquantitative measurement. BMD and an osteoporosis questionnaire were collected.

RESULTS

Overall spine fracture prevalence was 5.4 % and similar in men and women. Prevalence increased with age from <5 % in those <60 to 11 % in those 70-79 and 18 % in those ≥80 years. Fractures were more common in non-Hispanic whites and in people with lower body mass index and BMD. Among subjects with spine fracture, 26 % met BMD criteria for osteoporosis. Prevalence was higher in subjects who met National Osteoporosis Foundation (NOF) criteria for spine imaging (14 vs 4.7 %, P < 0.001). Only 8 % of people with a spine fracture diagnosed by VFA had a self-reported fracture, and among those who self-reported a spine fracture, only 21 % were diagnosed with fracture by VFA.

CONCLUSION

Spine fracture prevalence is similar in women and men and increases with age and lower BMD, although most subjects with spine fracture do not meet BMD criteria for osteoporosis. Since most (>90 %) individuals were unaware of their spine fractures, lateral spine imaging is needed to identify these women and men. Spine fracture prevalence was threefold higher in individuals meeting NOF criteria for spine imaging (∼1 in 7 undergoing VFA). Identifying spine fractures as part of comprehensive risk assessment may improve clinical decision making.

EULAR/EFORT recommendations for management of patients older than 50 years with a fragility fracture and prevention of subsequent fractures

The European League Against Rheumatism (EULAR) and the European Federation of National Associations of Orthopaedics and Traumatology (EFORT) have recognised the importance of optimal acute care for the patients aged 50 years and over with a recent fragility fracture and the prevention of subsequent fractures in high-risk patients, which can be facilitated by close collaboration between orthopaedic surgeons and rheumatologists or other metabolic bone experts. Therefore, the aim was to establish for the first time collaborative recommendations for these patients. According to the EULAR standard operating procedures for the elaboration and implementation of evidence-based recommendations, 7 rheumatologists, a geriatrician and 10 orthopaedic surgeons met twice under the leadership of 2 convenors, a senior advisor, a clinical epidemiologist and 3 research fellows. After defining the content and procedures of the task force, 10 research questions were formulated, a comprehensive and systematic literature search was performed and the results were presented to the entire committee. 10 recommendations were formulated based on evidence from the literature and after discussion and consensus building in the group. The recommendations included appropriate medical and surgical perioperative care, which requires, especially in the elderly, a multidisciplinary approach including orthogeriatric care. A coordinator should setup a process for the systematic investigations for future fracture risk in all elderly patients with a recent fracture. High-risk patients should have appropriate non-pharmacological and pharmacological treatment to decrease the risk of subsequent fracture.

Mind the (treatment) gap: a global perspective on current and future strategies for prevention of fragility fractures

This narrative review considers the key challenges facing healthcare professionals and policymakers responsible for providing care to populations in relation to bone health. These challenges broadly fall into four distinct themes: (1) case finding and management of individuals at high risk of fracture, (2) public awareness of osteoporosis and fragility fractures, (3) reimbursement and health system policy and (4) epidemiology of fracture in the developing world. Findings from cohort studies, randomised controlled trials, systematic reviews and meta-analyses, in addition to current clinical guidelines, position papers and national and international audits, are summarised, with the intention of providing a prioritised approach to delivery of optimal bone health for all. Systematic approaches to case-finding individuals who are at high risk of sustaining fragility fractures are described. These include strategies and models of care intended to improve case finding for individuals who have sustained fragility fractures, those undergoing treatment with medicines which have an adverse effect on bone health and people who have diseases, whereby bone loss and, consequently, fragility fractures are a common comorbidity. Approaches to deliver primary fracture prevention in a clinically effective and cost-effective manner are also explored. Public awareness of osteoporosis is low worldwide. If older people are to be more pro-active in the management of their bone health, that needs to change. Effective disease awareness campaigns have been implemented in some countries but need to be undertaken in many more. A major need exists to improve awareness of the risk that osteoporosis poses to individuals who have initiated treatment, with the intention of improving adherence in the long term. A multisector effort is also required to support patients and their clinicians to have meaningful discussions concerning the risk-benefit ratio of osteoporosis treatment. With regard to prioritisation of fragility fracture prevention in national policy, there is much to be done. In the developing world, robust epidemiological estimates of fracture incidence are required to inform policy development. As the aging of the baby boomer generation is upon us, this review provides a comprehensive analysis of how bone health can be improved worldwide for all.

Results of a fracture liaison service on hip fracture patients in an open healthcare system

We assessed osteoporosis management in patients admitted for rehabilitation of acute hip fracture to an open system community hospital before and after institution of a fracture liaison service (FLS). Pre-FLS, we surveyed 60 patients 4-6 months after hip fracture. Subsequently, the FLS program performed routine consultations, and recommended lab, bone density testing (BMD) and osteoporosis medication. FLS program outcomes were assessed by survey in 75 patients after hip fracture. In the pre-FLS population, after hip fracture, 55 % changed calcium intake, 48 % changed vitamin D intake, and 35 % obtained a BMD. Osteoporosis medication was taken by 38 % before and 33 % after hip fracture. Post-FLS, 56 % changed calcium intake, 68 % changed vitamin D intake and 65 % obtained a BMD. Post-FLS, osteoporosis medication was taken by 21 % of patients before and 19 % after hip fracture. Our FLS program in hip fracture patients improved non-pharmacologic measures, but not the use of osteoporosis medication.

Baseline Characteristics and Changes in Bone Mineral Density T-Scores of Bulgarian Women with Postmenopausal Osteoporosis Receiving Denosumab in Routine Clinical Practice

BACKGROUND

Postmenopausal osteoporosis (PMO) is common among women over 50 years of age and is associated with an increased risk of fracture. Bone-targeted agents, such as denosumab, can reduce fracture risk in patients with PMO.

OBJECTIVE

The aim was to describe baseline characteristics and changes in bone mineral density (BMD) T-scores among women with PMO receiving denosumab in Bulgaria.

METHODS

This multicenter chart review included women with PMO receiving denosumab for ≥1 year in Bulgaria (October 2011-August 2013). Participants were required to have a baseline BMD T-score of ≤-2.5 standard deviations (SDs) at one or more skeletal sites.

RESULTS

Overall, 222 women were included. The mean (SD) age at denosumab initiation was 64.2 (8.5) years; 26.6% reported a previous osteoporotic fracture and 6.8% a previous hip fracture. Only half of those reporting a previous fracture (49.2%) had received prior osteoporosis therapy. At baseline, mean (SD) BMD T-scores were lumbar spine -3.2 SD (0.6 SD), total hip -2.3 SD (0.8 SD), and femoral neck -2.7 SD (0.7 SD). After 1 year of denosumab treatment, scores increased significantly at all three sites, reaching -2.7 SD (0.6 SD), -2.1 SD (0.9 SD), and -2.4 SD (0.7 SD), respectively (all p < 0.0001 vs. baseline). No serious adverse drug reactions were identified.

CONCLUSION

Denosumab is usually prescribed in women with PMO at high fracture risk. In the patients who were persistent with treatment at 1 year, denosumab was well tolerated and effective at increasing BMD T-scores at several skeletal sites.

Effects of Age and Body Mass Index on Thoracolumbar Spine X-Ray for Diagnosing Osteoporosis in Elderly Women: Tianliao Old People (TOP) Study 07

PURPOSE

The aim of this study was to determine the effects of diagnostic discordance with or without a thoracolumbar spine lateral view X-ray in patients with osteoporosis.

METHODS

We randomly enrolled 368 women over 65 years old (74.3 ± 6.0 years) from Tianliao Township in 2009 (response rate: 75.7%). A diagnosis of osteoporosis was confirmed using one of these criteria: (1) a history of non-traumatic fracture, (2) vertebral fractures based on a thoracolumbar spine lateral view X-ray, or (3) a bone mineral density T-score ≤ -2.5 for the total hip, the femoral neck, the lumbar spine, or all 3 sites. The prevalence of osteoporosis in three groups was compared based on Model I (criteria 1+2) vs. Model II (criteria 1+3) vs. Model III (criteria 1+2+3). The role of thoracolumbar X-ray reflected by the diagnostic discordance of osteoporosis between Models II and III was evaluated.

RESULTS

The overall prevalence of osteoporosis was 78.3% (Model III, age-standardized 78.1%). The diagnostic discordance was 17.4% in the 368 participants. A logistic regression model showed that age was negatively associated with diagnostic discordance (odds ratio [OR] = 0.93, 95% confidence interval [CI]: 0.88-0.98, p < 0.05), but body mass index was positively associated (OR = 1.07, 95% CI: 1.00-1.15, p < 0.05).

CONCLUSIONS

A thoracolumbar spine lateral view X-ray should be added for women ≥ 65 years old or with a body mass index ≥ 25 kg/m2 to minimize the diagnostic discordance in osteoporosis, especially in highly endemic regions.

[Co-management in geriatric traumatology]

BACKGROUND

Fragility fractures are becoming more common and are leading to significantly increased morbidity and mortality rates.

METHOD

In order to improve the outcome of these patients, they are increasingly being treated from the beginning interdisciplinarily and interprofessionally as part of co-management models. The main contents of these systems are rapid surgical stabilization for rapid remobilization, treatment with standardized paths and regular communication within the team and a well-functioning discharge management. Furthermore, the organization is a key ingredient in secondary prevention of geriatric traumatology.

CONCLUSION

If this system can be implemented as a whole, this will lead to an improvement of the functional outcomes for the patient as well as to cost savings.

High prevalence of radiological vertebral fractures in adult patients with Ehlers-Danlos syndrome

Previous studies have reported an increased prevalence of osteoporosis in Ehlers–Danlos syndrome (EDS), but these were limited by a small number of patients and lack of information on fragility fractures. In this crosssectional study, we evaluated the prevalence of radiological vertebral fractures (by quantitative morphometry) and bone mineral density (BMD, at lumbar spine, total hip and femoral neck by dual-energy X-ray absorptiometry) in 52 consecutive patientswith EDS (10 males, 42 females; median age 41 years, range: 21–71; 12with EDS classic type, 37 with EDS hypermobility type, 1 with classic vascular-like EDS, and 2 without specific classification) and 197 control subjects (163 females and 34 males; median age 49 years, range: 26–83) attending an outpatient bone clinic. EDS patients were also evaluated for back pain by numeric pain rating scale (NRS- 11).Vertebral fractures were significantly more prevalent in EDS as compared to the control subjects (38.5% vs. 5.1%; p b 0.001) without significant differences in BMD at either skeletal sites. In EDS patients, the prevalence of vertebral fractures was not significantly (p = 0.72) different between classic and hypermobility types. BMD was not significantly different between fractured and non-fractured EDS patients either at lumbar spine (p = 0.14), total hip (p=0.08), or femoral neck (p=0.21). Severe back pain(≥7 NRS)was more frequent in EDS patients with vertebral fractures as compared to thosewithout fractures (60% vs. 28%; p=0.04). Inconclusion, this is the first study showing high prevalence of vertebral fractures in a relatively large population of EDS patients. Vertebral fractures were associated with more severe back pain suggesting a potential involvement of skeletal fragility in determining poor quality of life. The lack of correlation between vertebral fractures and BMD is consistent with the hypothesis that bone quality may be impaired in EDS.

Diagnosis of vertebral fractures using a low-dose biplanar imaging system

Vertebral fractures (VFs) are independent risk factors for new fractures. However, spine radiographs cannot be used as a screening method. EOS® has a good diagnostic value for the diagnosis of VF with a better legibility of upper thoracic spine and a higher concordance between readers compared to vertebral fracture assessment (VFA).

INTRODUCTION

Vertebral fractures (VFs) are risk factors for new fractures. However, spine radiographs cannot be used as a screening method for both cost and radiation concerns. EOS® X-ray imaging system which allows the acquisition of biplane images in an upright weight-bearing position with low radiation dose was used. The objective of this study was to compare EOS® to VFA for the diagnosis of VF.

METHODS

We conducted a cross-sectional study in subjects aged above 50 years with indication for spine imaging. EOS® and VFA of the spine were performed the same day. Sensitivity (Se), specificity (Sp), negative predictive value (NPV), and the interobserver precision of EOS® were compared to VFA for the diagnosis of VF.

RESULTS

Two hundred patients (mean age 66.2 years) were included. At the vertebral level, 2.4 and 3.6 % of vertebrae were not legible using EOS® and VFA, respectively (p = 0.0007). The legibility of spine was significantly affected by scoliosis (odds ratio (OR) = 2.8, p < 0.0001, for EOS®, and OR = 1.8, p = 0.0041, for VFA). Sixty-six patients (33.0 %) and 69 (34.5 %) had at least one VF using VFA and EOS®, respectively. At patient level, Se, Sp, and NPV for the diagnosis of VF of EOS® were 79.7, 91.6, and 99 %, respectively. Concordance between both observers was very good for EOS® (kappa-score = 0.89), higher than for VFA (κ = 0.67).

CONCLUSIONS

This study shows that EOS® has a good diagnostic value for the diagnosis of VF with a better legibility of upper thoracic spine and a higher concordance between readers compared to VFA.

Choosing the tool for osteoporosis risk prediction

PURPOSE OF REVIEW

Predicting fracture risk is a major challenge because it allows the prevention of major osteoporotic fracture in high-risk populations. With the aging of the population, this matter will become of even greater importance. In recent years, novel clinical, biochemical, and imaging tools have been developed to improve the assessment of fracture risk.

RECENT FINDINGS

The present review summarizes novel clinical strategies, Dual energy X-ray absorptiometry (DXA)-derived tools, imaging techniques, and biochemical markers that have been developed recently to improve fracture risk prediction.

SUMMARY

DXA and clinical fracture risk prediction tools are preferential markers of fracture risk. Clinical fracture risk alone might be used if DXA facilities are unavailable. The fracture risk assessment tool may be used in osteoporosis consultation in many countries. Other tools may be used soon after more studies are performed, particularly trabecular bone score, quantitative ultrasound, bone turnover markers. Specific factors for example falls, hip axis length, vertebral fracture assessment could be used in individual patients. This may significantly improve the clinical decision-making.

Hyperkyphosis and back pain are not associated with prevalent vertebral fractures in women with osteoporosis

Vertebral fractures (VFs) are the clinical consequence of spinal osteoporosis and may be associated with back pain and aggravated kyphosis. However, the relative importance of VFs as an underlying cause of kyphosis and chronic back pain is not known. The aim of this study was to investigate the relationship between prevalent VFs and the size of kyphosis, and back pain in osteoporotic women. Thirty-six women, aged 74.6 ± 8.3 years, were consecutively recruited from the osteoporosis unit at Uppsala University Hospital. The patients had 1-9 radiographic verified VFs. Tragus wall distance (TWD) and numeric rating scale were used to measure kyphosis and pain. All patients had a hyperkyphosis (TWD ≥ 10 cm). Notably, there were no associations between numbers or location of VFs versus size of kyphosis (ρ = 0.15, p = 0.4; ρ = -0.27, p = 0.12) or severity of back pain (ρ = -0.08, p = 0.66; ρ = 0.16, p = 0.35). Furthermore, no association was evident between kyphosis and back pain (ρ = -0.02, p = 0.89). There was, however, an association between size of kyphosis and age (R = 0.44, p = 0.008). In conclusion, these data suggest that prevalent VFs are not significantly associated with kyphosis or chronic back pain, in patients with manifest spinal osteoporosis.

Prediction models of prevalent radiographic vertebral fractures among older men

No studies have compared how well different prediction models discriminate older men who have a radiographic prevalent vertebral fracture (PVFx) from those who do not. We used area under receiver operating characteristic curves and a net reclassification index to compare how well regression-derived prediction models and nonregression prediction tools identify PVFx among men age ≥65 yr with femoral neck T-score of -1.0 or less enrolled in the Osteoporotic Fractures in Men Study. The area under receiver operating characteristic for a model with age, bone mineral density, and historical height loss (HHL) was 0.682 compared with 0.692 for a complex model with age, bone mineral density, HHL, prior non-spine fracture, body mass index, back pain, grip strength, smoking, and glucocorticoid use (p values for difference in 5 bootstrapped samples 0.14-0.92). This complex model, using a cutpoint prevalence of 5%, correctly reclassified only a net 5.7% (p = 0.13) of men as having or not having a PVFx compared with a simple criteria list (age ≥ 80 yr, HHL >4 cm, or glucocorticoid use). In conclusion, simple criteria identify older men with PVFx and regression-based models. Future research to identify additional risk factors that more accurately identify older men with PVFx is needed.

Secondary prevention of osteoporotic fractures: evaluation of the Amiens University Hospital's fracture liaison service between January 2010 and December 2011

SUMMARY

The main goal was to assess the performance of the fracture liaison service (FLS) at Amiens University Hospital for 2 years. Osteoporosis medication was prescribed in 182 patients and 67.4 % were still taking treatment 18 months later. Secondary prevention of osteoporotic fractures has improved since the creation of the FLS.

INTRODUCTION

The main goal of the present study was to assess the performance and results of the FLS at Amiens University Hospital, France.

METHODS

This was an observational, single-center, ambispective study. All patients admitted to Amiens University Hospital between January 2010 and December 2011 for a low-trauma fracture (vertebral and non-vertebral fractures) were identified by a FLS nurse. Patients willing to enter the study were assessed for their osteoporosis risk factors, daily calcium intake, bone mineral density (BMD) by DXA, and clinical chemistry parameters. When indicated, the patients received a prescription for osteoporosis medication. The participation rate, type of osteoporosis medications, initiation rate, and osteoporosis treatment persistence 12 and 18 months later were assessed.

RESULTS

Of the 1,439 patients contacted, 872 were eligible for inclusion. A total of 335 patients (participation rate 38.4 %) were included in the study (mean age 63.3 years; 71.9 % female). All patients underwent BMD measurement, and more than 90 % of them were assessed for osteoporosis risk factors and daily calcium intake. Osteoporosis medication was prescribed in 182 (75.5 %) of the patients in whom it was indicated (n = 241). The main class of osteoporosis medications prescribed was bisphosphonates (83.5 %), and 74.1 and 67.4 % of treated patients were still taking treatment 12 and 18 months later, respectively. The main cause of treatment discontinuation was non-renewal of the prescription by the patient's general practitioner.

CONCLUSION

Secondary prevention of osteoporotic fractures in Amiens University Hospital has improved since the creation of the FLS, with encouragingly high treatment initiation and persistence rates.

Lifetime, untreated isolated GH deficiency due to a GH-releasing hormone receptor mutation has beneficial consequences on bone status in older individuals, and does not influence their abdominal aorta calcification

The GH/IGF-I axis has essential roles in regulating bone and vascular status. The age-related decrease in GH secretion ("somatopause") may contribute to osteoporosis and atherosclerosis, commonly observed in the elderly. Adult-onset GH deficiency (GHD) has been reported to be associated with reduced bone mineral density (BMD), increased risk of fractures, and premature atherosclerosis. We have shown the young adult individuals with isolated GHD (IGHD) due to a homozygous for the c.57+1G>A GHRH receptor gene mutation have normal volumetric BMD (vBMD), and not develop premature atherosclerosis, despite adverse risk factor profile. However, the bone and vascular impact of lifetime GHD on the aging process remains unknown. We studied a group of ten older IGHD subjects (≥60 years) homozygous for the mutation, comparing them with 20 age- and gender-matched controls (CO). Areal BMD was measured, and vBMD was calculated at the lumbar spine and total hip. Vertebral fractures and abdominal aortic calcifications (expressed as calcium score) were also assessed. Areal BMD was lower in IGHD, but vBMD was similar in the two groups. The percent of fractured individuals was similar, but the mean number of fractures per individual was lower in IGHD than CO. Calcium score was similar in the two groups. A positive correlation was found between calcium score and number of fractures. Untreated lifetime IGHD has beneficial consequences on bone status and does not have a deleterious effect on abdominal aorta calcification.

Prediction models of prevalent radiographic vertebral fractures among older women

It is unknown how well prediction models incorporating multiple risk factors identify women with radiographic prevalent vertebral fracture (PVFx) compared with simpler models and what their value might be in clinical practice to select older women for lateral spine imaging. We compared 4 regression models for predicting PVFx in women aged 68 y and older enrolled in the Study of Osteoporotic Fractures with a femoral neck T-score ≤ -1.0, using area under receiving operator characteristic curves (AUROC) and a net reclassification index. The AUROC for a model with age, femoral neck bone mineral density, historical height loss (HHL), prior nonspine fracture, body mass index, back pain, and grip strength was only minimally better than that of a more parsimonious model with age, femoral neck bone mineral density, and historical height loss (AUROC 0.689 vs 0.679, p values for difference in 5 bootstrapped samples <0.001-0.35). The prevalence of PVFx among this older population of Caucasian women remained more than 20% even when women with low probability of PVFx, as estimated by the prediction models, were included in the screened population. These results suggest that lateral spine imaging is appropriate to consider for all Caucasian women aged 70 y and older with low bone mass to identify those with PVFx.

Orthogeriatrics moving forward

The role of the orthogeriatrician has grown over the last few years. Orthogeriatrics was primarily involved in the care and management of fragility hip fractures, but has recently been expanded to provide specialist care to patients admitted with other various fractures, the spine, pelvis, appendicular, and those suffered from major trauma. There is also an increasing role for the orthogeriatrician to optimise the pre-operative care of patients undergoing elective joint and spine surgery. Much of what we do incorporates comprehensive geriatric assessment of the frail older person, and research into new and innovative ways of managing various types of fragility fractures such as the use of enhanced recovery after surgery (ERAS) pathways, regional anaesthesia, vertebral augmentation in spinal fractures, sacral augmentation and anabolic treatment in pelvic fractures. Ultimately, this reduces post-operative complication rates, improves outcomes and leads to better patient care and recovery.

Vertebral fracture assessment (VFA) by lateral DXA scanning may be cost-effective when used as part of fracture liaison services or primary care screening

SUMMARY

We identified that use of VFA may be cost-effective in either selected women from primary care or women attending after a low trauma fracture.

INTRODUCTION

Lateral DXA scanning of the spine for vertebral fracture assessment (VFA) is used for research, but its wider role is unclear. We aimed to establish whether VFA is cost-effective in women based on two different scenarios: following a low-trauma fracture, and after screening of high-risk women identified in primary care.

METHODS

The fracture cohort (FC) consisted of 377 women and the primary care cohort (PCC) of 251. Vertebral fractures were identified on VFA images by quantitative morphometry (QM). Outcome was cost-effectiveness of VFA, based on predicted change in clinical management defined as the identification of a vertebral fracture in a patient who otherwise falls below the threshold for treatment. FRAX treatment thresholds assessed were (1) 20/3 % thresholds and (2) National Osteoporosis Guidelines Group (NOGG) thresholds.

RESULTS

As a result, 9.8 % from FC and 13.9 % from PCC were identified with vertebral fractures. Management was changed in 21 to 22/377 (5.6-5.8 %) in FC and 12 to 26/251 (4.8-10.4 %) from PCC depending on which thresholds were used. Sensitivity analyses identified medication adherence as the assumption which most influenced the model. The best-estimate cost-per-QALY for use of VFA in FC was £3,243 for 20/3 threshold and £2,130 for NOGG; for PCC, this was £7,831 for 20/3 and was cost-saving for NOGG. Further analyses to adjust for potential false-positive vertebral fracture identification with QM showed VFA was no longer cost-effective.

CONCLUSION

VFA appears to be cost-effective in routine clinical practise, particularly when relatively inaccurate methods of identification of vertebral fractures are used such as QM.

Decreased bone mineral density and periodontal management

The definition of osteoporosis has evolved beyond low bone mineral density to include impaired bone morphology and matrix properties. As such, the subsequent bone density insufficiencies extend beyond the skeletal risks of fracture and have implications for oral health management patients. As our population ages there is a worldwide increase in the risk of decreased bone mineral density and its subsequent morbidity. This makes age an independent risk factor for fracture and decreased bone mineral density. Multiple examinations and diagnostic tests are currently used in combination to develop an algorithm to assess osteoporotic risk. Oral health care professionals should follow these principles and caution should be used in applying a single independent assessment to determine a patient's osteoporotic or bone metabolism risk. Therapeutic approaches for osteoporosis are often divided into nonpharmacological interventions and pharmacological therapies. The periodontist and other oral health care professionals should have a full understanding of the therapeutic options, benefits and implementation of preventive therapies. Bone turnover is a coupled event of bone formation and bone resorption and it is the imbalance of this homeostasis that results in osteoporosis. Based on this uncoupling of bone resorption and formation, osteoporosis or decreased bone mineral density and osteopenia, may be a risk factor for alveolar bone loss in periodontitis. The role of prevention and maintenance with a history of periodontitis and oesteopenia extends beyond biofilm control and should include management of bone mineral density. The chronic periodontal infection in a patient with osteopenia may place the patient at greatly increased risk for alveolar bone loss, gingival recession and root caries. A key component in the management is the oral health professional's knowledge of the interrelationship between skeletal health and periodontal health.

Secondary prevention and estimation of fracture risk

The key questions addressed in this chapter are: • How can individual risk of fracture be best estimated? • What is the best system to prevent a further fracture? • How to implement systems for preventing further fractures? Absolute fracture risk calculators (FRCs) provide a means to estimate an individual's future fracture risk. FRCs are widely available and provide clinicians and patients a platform to discuss the need for intervention to prevent fragility fractures. Despite availability of effective osteoporosis medicines for almost two decades, most patients presenting with new fragility fractures do not receive secondary preventive care. The Fracture Liaison Service (FLS) model has been shown in a number of countries to eliminate the care gap in a clinically and cost-effective manner. Leading international and national organisations have developed comprehensive resources and/or national strategy documents to provide guidance on implementation of FLS in local, regional and national health-care systems.

Fracture Liaison Services in the United Kingdom

Fracture Liaison Services (FLS) have been demonstrated to be a clinically and cost-effective means of providing secondary preventive care for patients presenting with new fragility fractures. This review summarizes the emergence and widespread adoption of the FLS model in the United Kingdom. Large scale national audits have clearly illustrated the need for FLS by revealing the care gap experienced by the majority of patients who suffer fragility fractures. Since 2003, FLS has featured increasingly more prominently in relevant national professional guidance. During the last 5 years that professional consensus has led to FLS being embedded in government policy on fracture prevention. Quality incentives have been created to encourage hospitals and primary care providers to pro-actively deliver best practice. The strategic approaches taken and lessons learned in the UK may have relevance to quality improvement efforts in other jurisdictions.

A new antiresorptive approach to the treatment of fragility fractures: long-term efficacy and safety of denosumab

An imbalance of the remodeling process for bone resorption leads to a loss of tissue with consequent microarchitectural damage, evident in conditions such as osteoporosis and related fragility fractures. Currently, pharmacological therapies are able to prevent or slow down bone resorption by inhibiting osteoclast activity. An innovative and targeted anti-resorptive approach is represented by the inhibition of RANK ligand (RANK-L), essential for the proliferation and activity of osteoclastic cells. The human monoclonal antibody against RANK-L (denosumab) has been approved for the treatment of osteoporosis. In clinical trials of patients with osteoporosis, inhibition of RANK-L has reduced bone loss and damage to the microarchitecture and was associated with an increase in mass and resistance at different skeletal sites, with most significant effects than those demonstrated by any other antiresorptive drugs. In addition, after 3 years of treatment, it showed a reduction in vertebral and non-vertebral fracture risk. Denosumab treatment also has not revealed any alteration in the physiological processes of fracture repair, showing no increase in the onset of complications 3 years after the fracture. The data show that denosumab offers an effective alternative therapeutic approach for the treatment of severe osteoporosis, with positive effects on BMD and reduction of fragility fractures risk. So, promising results in terms of therapeutic efficacy and reliability make desirable the wide clinical use of denosumab for the treatment of osteoporotic fractures in the near future.

Vertebral fractures and self-perceived health in elderly women and men in a population-based cross-sectional study: the Tromsø Study 2007-08

Background

Health-related quality of life (HRQL) may be associated with increased mortality in the elderly. The effect of prevalent vertebral fractures on HRQL in elderly women and men is not well described. The purpose of this study was to examine the association between prevalent vertebral fractures and back pain, neck pain, and HRQL in elderly women and men, and to study possible gender differences in the reported pain and HRQL.

Methods

Information on prevalent vertebral fractures was ascertained by a vertebral fracture assessment (VFA) method (dual-energy X-ray absorptiometry (DXA), GE Lunar Prodigy) in 2887 women and men, mean age 65.4 (SD 9.4) who participated in the population-based Tromsø Study which was conducted in 2007–08. Bone mineral density (BMD; g/cm²) was measured by DXA at the femoral sites. Self-reported HRQL was assessed using the standardized measures EQ-5D-3 L and EQ VAS from the EuroQol Group. Lifestyle information was collected by questionnaires. The association between vertebral fractures and pain was analyzed using logistic regression, between vertebral fractures and EQ-5D-3 L and EQ VAS scores by multiple regression analyses.

Results

In women, presence of vertebral fractures was associated with an increased risk of back pain with an OR of 1.76 (95% CI: 1.24 – 2.50) after adjustments for age, height, weight, and BMD. Women with vertebral fractures had lower EQ-5D-3 L scores (p < 0.001) than women without vertebral fractures, also after adjustments. These associations were not present in men. Type of fracture was not associated with EQ-5D-3 L scores, but increasing numbers (p < 0.001) and severity of fractures (p < 0.002) were associated with decreasing EQ-5D-3 L score in women.

Conclusion

Prevalent vertebral fractures are associated with increased risk of back pain and reduced HRQL in postmenopausal women, but not in men.

Best practices in secondary fracture prevention: fracture liaison services

Fracture Liaison Services (FLS) have been demonstrated in many countries to provide an effective means to deliver secondary preventive care for patients presenting with fragility fractures. This review provides an update on journal articles, reports, guidelines and government policies, with relevance to FLS, which have been published during the period 2009-2012. International evidence of the extent and persistence of the secondary fracture prevention care gap has expanded during this period. Major professional and patient societies throughout the world, including the International Osteoporosis Foundation and the American Society for Bone and Mineral Research, have supported international initiatives to disseminate best practice. Health economic analysis of FLS has developed considerably, with a consistent theme from investigator-led and government analyses that FLS provide highly cost-effective care. Opportunities to close the care gap, in a systematic way, for unrecognised vertebral fracture sufferers are also considered.
