RESUMO

Objective: Several small studies reported increased prevalence and incidence of asymptomatic vertebral fractures in patients with non-functioning adrenal adenomas and adenomas with mild autonomous cortisol secretion. However, the risk of symptomatic fractures at vertebrae, and at other sites remains unknown. Our objective was to determine the prevalence and incidence of symptomatic site-specific fractures in patients with adrenal adenomas. Design: Population-based cohort study, Olmsted County, Minnesota, USA, 1995-2017. Methods: Participants were the patients with adrenal adenoma and age/sex-matched referent subjects. Patients with overt hormone excess were excluded. Main outcomes measures were prevalence and incidence of bone fractures. Results: Of 1004 patients with adrenal adenomas, 582 (58%) were women, and median age at diagnosis was 63 years (20-96). At the time of diagnosis, patients had a higher prevalence of previous fractures than referent subjects (any fracture: 47.9% vs 41.3%, P = 0.003, vertebral fracture: 6.4% vs 3.6%, P = 0.004, combined osteoporotic sites: 16.6% vs 13.3%, P = 0.04). Median duration of follow-up was 6.8 years (range: 0-21.9 years). After adjusting for age, sex, BMI, tobacco use, prior history of fracture, and common causes of secondary osteoporosis, patients with adenoma had hazard ratio of 1.27 (95% CI: 1.07-1.52) for developing a new fracture during follow up when compared to referent subjects. Conclusions: Patients with adrenal adenomas have higher prevalence of fractures at the time of diagnosis and increased risk to develop new fractures when compared to referent subjects.

RESUMO

This study demonstrated that number of three specific radiological risk factors (MR T2WI confined high-intensity pattern and diffuse low-intensity pattern, thoracolumbar vertebrae involvement, middle column injury) added prognostic information for delayed union, kyphotic deformity, and prolonged pain. PURPOSE: Delayed union after osteoporotic vertebral fracture (OVF) causes prolonged pain, QOL impairment, progression of collapse, kyphotic deformity, and neurologic impairment. Some specific radiological findings can be useful for predicting delayed union. We aimed to explore the prevalence and concomitance of various types of radiological risk factors for delayed union after osteoporotic vertebral fracture (OVF) and to assess the impact of risk factor number on clinical outcomes. METHODS: A total of 508 patients with fresh OVF from 25 institutes were evaluated. All patients were treated conservatively without surgical interventions. At the 6-month follow-up, the patients were classified into bone union and delayed union groups based on plain X-ray findings. We examined the presence and absence of three specific radiological risk factors (MR T2WI confined high-intensity pattern and diffuse low-intensity pattern, thoracolumbar vertebrae involvement, middle column injury) and analyzed clinical outcomes according to numbers of radiological risk factors. RESULTS: Delayed union was observed in 101 patients (19.9%) at the 6-month follow-up. The most common radiological risk factor was thoracolumbar vertebrae involvement (73.8%), followed by middle column injury (33.9%) and specific MRI findings (T2WI confined high-intensity pattern and diffuse low-intensity pattern) (29.7%). Overall, 85 (16.7%) patients had zero radiological risk factors, 212 (42.7%) had one, 137 (27.0%) had two, and 69 (13.6%) had three. When assessing the number of radiographic risk factors which included the MRI findings (the 3-risk factor method), the odds ratio for delayed union after acute OVF was 5.8 in the 2/3-risk factor group and 13.1 in the 3/3-risk factor group. Even when assessing the number of radiographic risk factors without MRI findings (2-risk factor method), the odds ratio was 3.2 in the 1/2-risk factor group and 10.2 in the 2/2-risk factor group. CONCLUSION: Number of radiological risk factors added prognostic information for delayed union, kyphotic deformity, and prolonged pain.

RESUMO

This study examines changes in bone density and strength in the spine over the year after hip fracture to see if there are differences in the changes between men and women. Results show losses in the spine that may increase the risk of subsequent vertebral fractures, particularly for women. PURPOSE: Compare changes over the first year post-hip fracture in vertebral bone mineral density (BMD) and compressive strength, measured from quantitative computed tomography (QCT) scans of the spine (T12-L1), between women and men. METHODS: QCT scans were performed on 37 participants (21 men and 16 women) at 2 and 12 months post-hip fracture as part of an ancillary observational study of hip fracture recovery in older community-dwelling men and women. Vertebral BMD and compressive strength were calculated using VirtuOst® (O.N. Diagnostics, Berkeley, CA). Unpaired t-tests were used to compare men and women with respect to baseline demographics, measurements of BMD and bone strength for the whole vertebra and the cortical and trabecular compartments, and any changes in these parameters between months 2 and 12. RESULTS: At 2 months post-fracture, there were no significant sex differences in any measurements of vertebral strength or BMD. Between months 2 and 12, vertebral strength decreased significantly in women (- 3.8%, p < 0.05) but not in men (- 2.3%, p < 0.20), vertebral trabecular BMD decreased similarly in both sexes (- 5.7% women; - 6.0% men), but cortical BMD did not change for either sex. CONCLUSION: Despite the small sample size, these findings suggest that appreciable loss of vertebral trabecular bone can occur for both sexes in the year following hip fracture, which may increase the risk of subsequent vertebral fracture, particularly for women.

RESUMO

BACKGROUND: To systematically evaluate the efficacy of teriparatide and bisphosphonates in preventing fractures in postmenopausal women with osteoporosis. MATERIALS AND METHODS: We performed a systematic search of PubMed, Embase, and the Cochrane Library for randomized controlled trials (RCTs) that compared teriparatide and bisphosphonates for osteoporosis treatment. Searches were performed without language restrictions and included studies from beginning of time to March 2019. Two authors independently screened and extracted the selected article. The quality of the included studies was evaluated using the Cochrane system evaluation method. Data were extracted and analysed using RevMan 5.2 software. RESULTS: Nine RCTs were included for a total of 2990 postmenopausal women with osteoporosis. Of these, 1515 patients were treated with teriparatide and 1475 were treated with bisphosphonates. After pooling the data of 9 studies, there were significant differences between teriparatide and bisphosphonates [relative risk (RR): 0.61, 95% confidence interval (CI) (0.51, 0.74)] in the prevention of fractures according to different follow-up durations (P < .05), whatever alendronate [RR: 0.51, 95% CI (0.27, 0.95)] and other bisphosphonates [RR: 0.63, 95% CI (0.51, 0.77)]. In addition, we found significant differences between teriparatide and bisphosphonates in the prevention of vertebral fractures [RR: 0.47, 95% CI (0.35, 0.64)] and non-vertebral fractures [RR: 0.76, 95% CI (0.58,0.99)]. There were no significant differences in adverse effects between teriparatide and bisphosphonates [RR: 0.89, 95% CI (0.76, 1.03)]. CONCLUSIONS: Based on the results of our meta-analysis, teriparatide was better than bisphosphonates in preventing fractures in postmenopausal women with osteoporosis both in the short-term and long-term follow-up periods. Teriparatide was superior to bisphosphonates in preventing vertebral and non-vertebral fractures. These drugs did not differ in terms of their adverse effects. More high-quality studies are needed to compare other factors such as costs and adverse reactions.

RESUMO

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.

RESUMO

We investigated the effect of paravertebral muscle (PVM) on poor prognosis in osteoporotic vertebral fracture (OVF) and remaining lower back pain (LBP) in the thoracolumbar and lower lumbar regions. Additional OVF occurrence in the thoracolumbar and remaining LBP in the lumbar region was significantly related to PVM fat infiltration percentage. PURPOSE: Paravertebral muscle (PVM) is an important component of the spinal column. However, its role in the healing process after osteoporotic vertebral fracture (OVF) is unclear. This study aimed to clarify the effect of PVM in thoracolumbar and lower lumbar regions on OVF clinical and radiological outcomes. METHODS: This was a multicenter prospective cohort study from 2012 to 2015. Patients ≥ 65 years old who presented within 2 weeks after fracture onset were followed up for 6 months. PVM was measured at the upper edge of the L1 and L5 vertebral body in the magnetic resonance imaging (MRI) T2-axial position at registration. The cross-sectional area (CSA), relative CSA (rCSA), and fat infiltration percentage (FI%) were measured. Severe vertebral compression, delayed union, new OVF, and remaining low back pain (LBP) were analyzed. RESULTS: Among 153 patients who were followed up for 6 months, 117 with measurable PVM were analyzed. Their average age was 79.1 ± 7.2 years, and 94 were women (80.3%). There were 48 cases of severe vertebral compression, 21 delayed unions, 11 new OVF, and 27 remaining LBP. Among all poor prognoses, only the FI% of the PVM was significantly associated with new OVF (p = 0.047) in the thoracolumbar region and remaining LBP (p = 0.042) in the lumbar region. CONCLUSION: The occurrence of additional OVF in the thoracolumbar region and remaining LBP in the lumbar region was significantly related to the FI% of the PVM. Physicians should be aware that patients with such fatty degeneration shown in acute MRI may require stronger treatment.

RESUMO

The aim was to compare the National Osteoporosis Foundation (NOF) and the UK National Osteoporosis Guideline Group (NOGG) guidelines for the detection of vertebral fractures in postmenopausal Chinese women. The NOF guidelines had higher accuracy than the UK guidelines for spinal radiography examination. PURPOSE: To compare the National Osteoporosis Foundation (NOF) and the UK National Osteoporosis Guideline Group (NOGG) guidelines for the detection of vertebral fractures in postmenopausal Chinese women. METHODS: A cross-sectional study on 255 community-dwelling postmenopausal women was conducted in Hunan province in 2017. Demographic and clinical characteristics and risk factors were recorded through questionnaires. Height and weight were measured using standard methods, and bone mineral density (BMD) was measured with dual-energy X-ray absorptiometry. Vertebral fractures were diagnosed by radiography using semi-quantitative morphometry. RESULTS: The prevalence of vertebral fractures was 9.4%. Women with vertebral fractures were significantly older and shorter, had higher years-since menopause and height loss values and lower BMD and T-scores at the femoral neck and total hip, and were more likely to have a history of previous fractures. The sensitivity and specificity of the NOF guidelines were 91.7% and 39.8%, respectively, while the NOGG guidelines had lower sensitivity (87.5%) and specificity (32.5%). However, a higher percentage had indications for radiography in the 50-64 years age group according to the NOGG guidelines, while a higher percentage had indications for radiography in the ≥ 65 year group according to the NOF guidelines. CONCLUSIONS: The NOF guidelines were better than the NOGG guidelines for spinal radiography examination in the Chinese postmenopausal women.

RESUMO

STUDY DESIGN: Retrospective cohort study. OBJECTIVE: Assess trends in sports-related cervical spine trauma using a pediatric inpatient database. SUMMARY OF BACKGROUND DATA: Injuries sustained from sports participation may include cervical spine trauma such as fractures and spinal cord injury (SCI). Large database studies analyzing sports-related cervical trauma in the pediatric population are currently lacking. METHODS: The Kid Inpatient Database was queried for patients with external causes of injury secondary to sports-related activities from 2003 to 2012. Patients were further grouped for cervical spine injury (CSI) type, including C1-4 and C5-7 fracture with/without spinal cord injury (SCI), dislocation, and SCI without radiographic abnormality (SCIWORA). Patients were grouped by age into children (4-9), pre-adolescents (Pre, 10-13), and adolescents (14-17). Kruskall-Wallis tests with post-hoc Mann-Whitney U's identified differences in CSI type across age groups and sport type. Logistic regression found predictors of TBI and specific cervical injuries. RESULTS: A total of 38,539 patients were identified (12.76 years, 24.5% F). Adolescents had the highest rate of sports injuries per year (P < 0.001). Adolescents had the highest rate of any type of CSI, including C1-4 and C5-7 fracture with and without SCI, dislocation, and SCIWORA (all P < 0.001). Adolescence increased odds for C1-4 fracture w/o SCI 3.18×, C1-4 fx w/ SCI by 7.57×, C5-7 fx w/o SCI 4.11×, C5-7 w/SCI 3.63×, cervical dislocation 1.7×, and cervical SCIWORA 2.75×, all P < 0.05. Football injuries rose from 5.83% in 2009 to 9.14% in 2012 (P < 0.001), and were associated with more SCIWORA (1.6% vs. 1.0%, P = 0.012), and football injuries increased odds of SCI by 1.56×. Concurrent TBI was highest in adolescents at 58.4% (pre: 26.6%, child: 4.9%, P < 0.001), and SCIWORA was a significant predictor for concurrent TBI across all sports (odds ratio: 2.35 [1.77-3.11], P < 0.001). CONCLUSION: Adolescent athletes had the highest rates of upper/lower cervical fracture, dislocation, and SCIWORA. Adolescence and SCIWORA were significant predictors of concurrent TBI across sports. The increased prevalence of CSI with age sheds light on the growing concern for youth sports played at a competitive level, and supports recently updated regulations aimed at decreasing youth athletic injuries. LEVEL OF EVIDENCE: 3.

RESUMO

BACKGROUND: Glucocorticoids are widely used in a variety of diseases, especially autoimmune diseases and inflammatory diseases, so the incidence of glucocorticoid-induced osteoporosis is high all over the world. OBJECTIVES: The purpose of this paper is to use the method of network meta-analysis (NMA) to compare the efficacy of anti-osteoporosis drugs directly and indirectly, and to explore the advantages of various anti-osteoporosis drugs based on the current evidence. METHODS: We searched PubMed, Embase and Cochrane Library for randomized controlled trials (RCTs), of glucocorticoid-induced osteoporosis (GIOP) and compared the efficacy and safety of these drugs by NMA. The risk ratio (RR) and its 95% confidence interval (CI) are used as the influence index of discontinuous data, and the standardized mean difference (SMD) and its 95% CI are used as the influence index of continuous data. The statistical heterogeneity was evaluated by the calculated estimated variance (τ2), and the efficacy and safety of drugs were ranked by the surface under the cumulative ranking curve (SUCRA). The main outcome of this study was the incidence of vertebral fracture after taking several different types of drugs, and the secondary results were the incidence of non-vertebral fracture and adverse events, mean percentage change of lumbar spine (LS) and total hip (TH)bone mineral density (BMD) from baseline to at least 12 months. RESULTS: Among the different types of anti-GIOP, teriparatide (SUCRA 95.9%) has the lowest incidence of vertebral fracture; ibandronate (SUCRA 75.2%) has the lowest incidence of non-vertebral fracture; raloxifene (SUCRA 98.5%) has the best effect in increasing LS BMD; denosumab (SUCRA 99.7%) is the best in increasing TH BMD; calcitonin (SUCRA 92.4%) has the lowest incidence of serious adverse events. CONCLUSIONS: Teriparatide and ibandronate are effective drugs to reduce the risk of vertebral and non-vertebral fractures in patients with GIOP. In addition, long-term use of raloxifene and denosumab can increase the BMD of LS and TH.

RESUMO

BACKGROUND: The goal of this study was to review relevant randomized controlled trials or case-control studies to determine the clinical efficacy of minodronate in the treatment of osteoporosis. METHOD: The relevant studies were identified on PubMed, Cochrane, and Embase databases using appropriate keywords. Pertinent sources in the literature were also reviewed, and all articles published through October 2019 were considered for inclusion. For each study, we assessed odds ratios, mean difference, and 95% confidence interval (95% CI) to evaluate and synthesize outcomes. RESULT: Thirteen studies comprising 3740 patients were included in this study. Compared with other drugs, minodronate significantly decreased N-telopeptide of type I collagen/creatinine (weighted mean difference [WMD]: -13.669, 95% confidence interval [CI]: -23.108 to -4.229), bone alkaline phosphatase (BAP) (WMD: -1.26, 95% CI: -2.04 to -0.47) and tartrate-resistant acid phosphatase 5b (WMD: -154.11, 95% CI: -277.85 to -30.37). Minodronate combined with other drugs would significantly decrease BAP (WMD: -3.10, 95% CI: -5.20 to -1.00) than minodronate. Minodronate-naïve would significantly decrease BAP (WMD: -3.00, 95% CI: -5.47 to 0.53) and tartrate-resistant acid phosphatase 5b (WMD: -128.20, 95% CI: -198.11 to -58.29) than minodronate-switch. The incidence of vertebral fracture was significantly decreased in the minodronate group than the other drugs (relative risk: 0.520, 95% CI: 0.363-0.744). CONCLUSION: Minodronate has better clinical efficacy in the treatment of osteoporosis than other drugs (alendronate, risedronate, raloxifene, or eldecalcitol).

RESUMO

We introduced a standardised reporting system in the radiology department to highlight vertebral fractures and to signpost fracture prevention services. Our quality improvement project achieved improved fracture reporting, access to the FLS service, bone density assessment and anti-fracture treatment. PURPOSE: Identification of vertebral fragility fractures (VF) provides an opportunity to identify individuals at high risk who might benefit from secondary fracture prevention. We sought to standardise VF reporting and to signpost fracture prevention services. Our aim was to improve rates of VF detection and access to our fracture liaison service (FLS). METHODS: We introduced a standardised reporting tool within the radiology department to flag VFs with signposting for referral for bone densitometry (DXA) and osteoporosis assessment in line with Royal Osteoporosis Society guidelines. We monitored uptake of VF reporting during a quality improvement phase and case identification within the FLS service. RESULTS: Recruitment of individuals with VF to the FLS service increased from a baseline of 63 cases in 2017 (6%) to 95 (8%) in 2018 and 157 (8%) in 2019 and to 102 (12%) in the first 6 months of 2020 (p = 0.001). One hundred fifty-three patients with VFs were identified during the QI period (56 males; 97 females). Use of the terminology 'fracture' increased to 100% (mean age 70 years; SD 13) in computed tomography (n = 110), plain X-ray (n = 37) or magnetic resonance imaging (n = 6) reports within the cohort. Signposting to DXA and osteoporosis assessment was included in all reports (100%). DXA was arranged for 103/153; 12 failed to attend. Diagnostic categories were osteoporosis (31%), osteopenia (36%) or normal bone density (33%). A new prescription for bone protection therapy was issued in 63/153. Twelve of the series died during follow-up. CONCLUSIONS: Standardisation of radiology reporting systems facilitates reporting of prevalent vertebral fractures and supports secondary fracture prevention strategies.

RESUMO

Using the claim database, we investigated the incidence rate of clinical vertebral fractures per 1,000 in the elderly residents, over 65 years of age, in Kure city. The incidence rate, of clinical vertebral fractures, was 15.58 (7.29 male, 21.17 female, 2.90 female/male ratio). PURPOSE: To elucidate the incidence of clinical vertebral and hip fractures using the claim database, in those over 65 years of age in Kure city, and to compare with the previous reports. METHODS: We used, for residents in 2015, the medical care information of the National Health Insurance or Senior Elderly Care System in Kure City (Hiroshima Prefecture, Japan). Those with vertebral fractures as disease name, and either treatment/operation/hospitalization were defined as clinical vertebral fractures. Among the claim database, we extracted the clinical vertebral fracture and investigated the number of occurrences and the incidence rate per 1,000. We also investigated the incidence rate of hip fractures and compared those to the clinical vertebral fractures. RESULT: The incidence rate of clinical vertebral fractures of the elderly population (65 years or over) per 1,000 was 15.58 (7.29 male, 21.17 female, 2.90 female/male ratio). In both men and women, the incidence rate increased with aging. The incidence rate of hip fractures per 1,000 was 9.17 (3.55 male, 12.96 female, 3.65 male/female ratio). Clinical vertebral fractures were more frequent than hip fractures, and the ratio of incidence rate of vertebral fractures to hip fractures was 1.70 (male, 2.05, female, 1.63). For both fractures, the incidence rate increases with age, apart from the women where the incidence of vertebral fracture reduces slightly in the older age group CONCLUSION: This is the first report that investigated the incidence rate of the clinical vertebral fractures using the claim database, which covered almost the whole number of 230,000 population area.

RESUMO

Traumatic end plate fractures (EPFs) refers to the EPF caused by trauma, rather than the pathological status of the end plate (EP). However, some old traumatic EPFs may be mistaken as osteoporotic in the elderly. The objective of this study is to describe the radiological features of traumatic EPF in different traumatic fracture type patients presenting in the Emergency department setting. And to compare the result with osteoporotic vertebral fracture (VF).This study retrospectively analyzed the anatomical location of acute thoracolumbar vertebral traumatic EPFs in males (age≤55 years) and females (age≤50 years). The anatomic distribution of EPFs, the anterior and posterior wall fracture were analyzed in patients, who were scanned with 1 or more of the following methods: radiography, CT, and magnetic resonance imaging.There were 194 cases of acute spine trauma involving at least 1 EPF, including 118 males and 76 females. The involved vertebra was mostly at L1 (29.7%), followed by T12 (18.3%), and then by L2 (12.9%). Excluding those with both upper and lower EP involvements, the ratio of superior EPF to inferior EPF was 33.5 for males and 45.5 for females. With the EP divided into 5 segments of equal length in the anteroposterior direction in different fracture types, fractures occurred mostly at a2 segment (71.48% for superior EPs and 7.60% for inferior EPs), followed by a1 segment (66.16% for superior EPs). The upper third of the anterior and posterior walls were most prone to fracture in traumatic vertebral fracture.Traumatic EPFs more likely involve the anterior EP more than the posterior EP and is correlated with fracture type. These characteristics may help radiologist differential diagnosis between traumatic and osteoporotic EPF.

RESUMO

BACKGROUND: The BenchMarket Medical (BMM) Vertebral Compression Fracture (VCF) Registry, now known as Talosix, is a collaborative effort between Talosix (the authorized registry vendor), Noridian Healthcare Solutions, and clinicians to gather outcomes evidence for cement augmentation treatments in patients with acute painful osteoporotic VCFs. The VCF Registry was designed to provide outcomes evidence to inform the Medicare payer's "coverage with evidence development" decision to authorize reimbursement for cement augmentation treatments. OBJECTIVES: The purpose of this article was to present a pathway for appropriate use of vertebral augmentation based on the findings of the VCF Registry. STUDY DESIGN: Prospective observational data, including patient characteristics, diagnosis, process of care, and patient-reported outcomes (PROs) for pain and function, were collected from patients undergoing cement augmentation treatment. The PROs were collected at baseline, 1, 3, and 6 months following the procedure. SETTING: The VCF Registry is a national ongoing registry with no specified end time or designated sample size. METHODS: Primary outcomes were pain improvement measured using the Numeric Rating Scale and function improvement, measured using the Roland Morris Disability Questionnaire (RMDQ). Secondary outcomes included cement leakage, new neurologic deficits, adverse events, readmissions, and death. RESULTS: The VCF Registry delivered outcomes data to support Noridian's "coverage with evidence development" decision. A total of 732 patients were included in this study. Registry outcomes confirmed postmarket evidence of highly significant pain relief with mean pain score improvement of 6.5/10 points at 6 months. Function also improved significantly with mean RMDQ score change of 11.4/24 points 6 months after surgery. Results also showed the safety and reliability of cement augmentation. LIMITATIONS: The nature of the registry data is that it contains nonrandomized, nonplacebo controlled data and should not be perceived as such. The real-world setting and the large number of patients within the dataset should increase the external validity of the findings. CONCLUSIONS: Cement augmentation treatments of patients with acute painful VCFs reliably results in highly significant benefits of pain decrease and functional improvement for this Medicare population. KEY WORDS: Vertebral compression fractures, osteoporosis, kyphoplasty, back pain, registry.

RESUMO

Objective: Growth hormone (GH) and insulin-like growth factor 1 (IGF-1) excess results in both reversible and irreversible musculoskeletal damage, including increased vertebral fracture (VF) risk. The prevalence of VFs is approximately 60% in controlled acromegaly patients, and these VFs can progress in time. We aimed to identify the course of VFs in a cohort of acromegaly patients in long-term remission and their associated risk factors during prolonged follow-up. Methods: Thirty-one patients with acromegaly (49% female, median age 60 years (IQR 53-66)), who were in remission for ≥2 years, were included in this longitudinal, prospective, follow-up study. Spine radiographs of vertebrae Th4 to L4 were assessed for VFs using the Genant score, at baseline, after 2.6 years and 9.1 years. Progression was defined as either a new fracture or a ≥1-point increase in Genant score. Results: The prevalence of VF at baseline was 87% (27/31 patients). Progression of VFs was observed in eleven patients (35.5%) during the 9.1-year follow-up period, with a total incidence rate of 65.5 per 1000 person years (males 59.8 per 1000 person years vs females 71.6 per 1000 person years). Patients treated with surgery or radiotherapy had a higher risk of VF progression in this cohort (P = 0.030). Conclusions: In this cohort of long-term, well-controlled acromegalic patients, the prevalence and progression of VFs was high, showing that the deleterious effects of GH and IGF-1 excess on bone persist despite achievement of longstanding remission.

RESUMO

Among 39,475 women, age 65 years and older, use of fracture history, major osteoporotic fracture (MOF) probability from FRAX®, vertebral fracture assessment (VFA), and bone mineral density (BMD) T-score stratified women into different levels of risk. The majority of women identified as being at high risk from fracture history, FRAX MOF-BMD > 20%, or vertebral fracture on VFA had a BMD T-score in the osteoporotic range. PURPOSE: To inform criteria for pharmacologic treatment in women age 65 years and older, we examined subgroups defined from fracture history, MOF calculated with BMD (MOF-BMD), VFA, and BMD T-score using the population-based Manitoba BMD Program registry. METHODS: The study population consisted of women age > 65 years was divided into mutually exclusive subgroups based upon fracture history, MOF-BMD ≥ 20%, vertebral fracture on VFA, and osteoporotic BMD T-score. Healthcare records were assessed for the presence of fracture diagnosis codes occurring after DXA assessment. For each subgroup, we estimated the proportion of individuals with BMD T-score in the osteoporotic range, predicted versus observed 10-year MOF probability, hazard ratio (HR) for MOF, and number needed to treat (NNT) for 3 years to prevent a fracture event. RESULTS: The study population consisted of 39,475 women (median age 72 years). The majority of women (76.8%) selected as being at high risk based on fracture history, MOF-BMD > 20%, or vertebral fracture on VFA had a BMD T-score in the osteoporotic range. During a median follow-up of 8 years, 5169 (13.1%) sustained one or more incident MOF. Fracture rates and HRs generally paralleled the FRAX prediction, except in women with a positive VFA where predicted risk based upon clinical risk factors prior to VFA underestimated the observed risk. NNT differed by the risk subgroup, and showed a gradient of decreasing NNT (consistent with greater benefit) in individuals with the highest fracture risk. CONCLUSIONS: Fracture history, fracture probability from FRAX, targeted vertebral fracture assessment (VFA), and BMD T-score can stratify older women into different levels of risk and treatment benefit. These results are expected to inform clinical practice guidelines in Canada.

RESUMO

Vertebral compression fractures (VCFs) are common in elderly and are treated with immobilization. Moreover, immobilization and old age may increase venous thromboembolism (VTE) risk. However, the incidence of VCFs-related VTE is unknown in elderly. The purposes of this study were to determine the incidence of VTE among VCF patients, to explore whether percutaneous vertebroplasty (PV) intervention may reduce VTE risk in VCFs patients.We conducted a population-based case-control study by using the National Health Insurance Research Database. We identified 1407 patients aged ≥65 with VCF who received PV and 1407 VCFs patients who did not receive PV after developing a 1:1 propensity score-matched study cohort and were followed up for 5 years. Using PV intervention as the exposure factor, a cause-specific Cox's proportional hazards model was used to examine the association between PV and VTE.After propensity score matching, the mean age of the study participants was 78 years and ∼23% of the analyzed participants were men, incidence of VTE in the PV and control cohorts was 5.77 and 4.19 per 1000 person-years, respectively. Both groups were nonsignificant difference after examination with different adjustment models. Patients with VCF and a history of heart failure, coronary artery disease, receiving antihypertension medication were at a significantly increased VTE risk.Elderly patients with VCF who received PV had a neutral impact on risk of VTE. VCF patients with heart failure, coronary artery disease, and receiving antihypertension medication were prone to developing VTE should be monitored cautiously.

RESUMO

OBJECTIVE: The risk of complications of nonsurgical hypoparathyroidism in Asia is unclear. We estimated the prevalence and risk of complications in patients with nonsurgical hypoparathyroidism. METHODS: We performed a retrospective cohort study using a nationwide claims database from 2005 to 2016. Among the entire Korean population, we identified 897 patients diagnosed with nonsurgical hypoparathyroidism during 2005-2015. We selected 210 patients with nonsurgical hypoparathyroidism during 2005-2008 who had no complications at baseline and followed them to 2016. Control subjects (n = 2075) were matched using propensity scores based on age, sex, and comorbid disease with a 1:10 ratio and monitored until 2016. RESULTS: The age-standardized prevalence of nonsurgical hypoparathyroidism was 0.2 cases per 100,000 persons in 2005. During a mean follow-up period of 9.5 years, patients with nonsurgical hypoparathyroidism had a higher risk of cardiovascular disease, especially arrhythmia (hazard ratio [HR], 2.03; 95% confidence interval [CI], 1.11-3.70) and heart failure (HR, 2.43; 95% CI, 1.22-4.83). The risk of vertebral fracture was higher in patients than in controls (HR, 2.27; 95% CI, 1.09-4.72). Patients had a significantly increased risk of renal disease (HR, 2.57; 95% CI, 1.56-4.21), seizure (HR, 5.74; 95% CI, 3.34-9.86), depression and bipolar disease (HR, 1.82; 95% CI, 1.30-2.56), and cataract (HR, 1.90; 95% CI, 1.30-2.79) compared with controls. CONCLUSIONS: The prevalence of nonsurgical hypoparathyroidism was very low in Korea but was associated with a higher risk of incident cardiovascular disease and vertebral fracture as well as known complications including renal disease, seizure, and cataract.

RESUMO

Vertebral fracture assessment (VFA) provides incremental information in identifying women and men aged 70 years and older qualifying for anti-osteoporosis treatment compared with FRAX® major osteoporotic fracture (MOF) probability computed with bone mineral density (BMD). PURPOSE: This analysis was performed to inform appropriate use of VFA testing as part of Osteoporosis Canada's Guidelines Update, assuming vertebral fracture is an indication for pharmacotherapy in women and men. METHODS: Women and men aged 70 years and older without previous high-risk fracture (i.e., hip, spine, or multiple fractures) were identified in a BMD registry for the province of Manitoba, Canada. MOF probability with BMD was computed using the Canadian FRAX® tool. VFA was performed in those with a minimum BMD T-score of -1.5 or lower. RESULTS: The study population consisted of 7289 women (mean age 76.7 ± 5.6 years) and 1323 men (77.9 ± 5.8 years). More women than men qualified for VFA testing (48.7% vs 25.4%, respectively, p < 0.001). Among those undergoing VFA, a vertebral fracture was more commonly detected among men than women (22.9% vs 13.3%, p < 0.001), and vertebral fracture prevalence increased with lower BMD T-score (both p trend <0.001). The number needed to screen with VFA to detect a vertebral fracture was 8 for women and 4 for men. MOF probability was substantially lower in men than in women, and fewer men than women (3.3% vs 20.2%, p < 0.001) met a treatment threshold of MOF 20% or greater. In those with MOF probability <20%, VFA identified an incremental 5.4% of men and 3.4% of women for treatment based upon vertebral fracture. CONCLUSIONS: The number needed to screen to identify a previously unappreciated vertebral fracture is low and further improves with lower BMD T-score. VFA identified more men as qualifying for treatment than MOF probability. In women, treatment qualification was predominantly from MOF probability.

RESUMO

BACKGROUND: It is unclear whether anticoagulant type is associated with the risk for osteoporotic fracture, a deleterious complication of anticoagulants among patients with atrial fibrillation (AF). OBJECTIVE: To compare the risk for osteoporotic fracture between anticoagulants. DESIGN: Population-based cohort study. SETTING: Territory-wide electronic health record database of the Hong Kong Hospital Authority. PARTICIPANTS: Patients newly diagnosed with AF between 2010 and 2017 who received a new prescription for warfarin or a direct oral anticoagulant (DOAC) (apixaban, dabigatran, or rivaroxaban). Follow-up ended on 31 December 2018. MEASUREMENTS: Osteoporotic hip and vertebral fractures in anticoagulant users were compared using propensity score-weighted cumulative incidence differences (CIDs). RESULTS: There were 23 515 patients identified (3241 apixaban users, 6867 dabigatran users, 3866 rivaroxaban users, and 9541 warfarin users). Overall mean age was 74.4 years (SD, 10.8), ranging from 73.1 years (warfarin) to 77.9 years (apixaban). Over a median follow-up of 423 days, 401 fractures were identified (crude event number [weighted rate per 100 patient-years]: apixaban, 53 [0.82]; dabigatran, 95 [0.76]; rivaroxaban, 57 [0.67]; and warfarin, 196 [1.11]). After 24-month follow-up, DOAC use was associated with a lower risk for fracture than warfarin use (apixaban CID, -0.88% [95% CI, -1.66% to -0.21%]; dabigatran CID, -0.81% [CI, -1.34% to -0.23%]; and rivaroxaban CID, -1.13% [CI, -1.67% to -0.53%]). No differences were seen in all head-to-head comparisons between DOACs at 24 months (apixaban vs. dabigatran CID, -0.06% [CI, -0.69% to 0.49%]; rivaroxaban vs. dabigatran CID, -0.32% [CI, -0.84% to 0.18%]; and rivaroxaban vs. apixaban CID, -0.25% [CI, -0.86% to 0.40%]). LIMITATION: Residual confounding is possible. CONCLUSION: Among patients with AF, DOAC use may result in a lower risk for osteoporotic fracture compared with warfarin use. Fracture risk does not seem to be altered by the choice of DOAC. These findings may help inform the benefit-risk assessment when choosing between anticoagulants.
