Oral Frailty as a Risk Factor for Fall Incidents among Community-Dwelling People. Geriatrics (Basel) 2024; 9:54. [PMID: 38667521 PMCID: PMC11050511 DOI: 10.3390/geriatrics9020054] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2024] [Revised: 04/04/2024] [Accepted: 04/18/2024] [Indexed: 04/28/2024] Open
Abstract
BACKGROUND Identifying older adults with a high risk of falling and providing them with appropriate intervention are vital measures for preventing fall incidents. Scholars report that oral frailty, a decline in oral function, is related to physical function; thus, it bears a potential association with fall risks. This study aimed to investigate the relationship between fall incidents and the status of physical and oral frailty among a sample of residents in Osaka Prefecture. SUBJECTS AND METHODS This study targeted community-dwelling people aged 50 years and older who responded to an annual questionnaire survey using a health app for 2 consecutive years, namely, 2020 and 2021. This study analyzed responses from 7591 (62 ± 7 years) participants and determined the status of their oral frailty and comprehensive and physical frailty using the Kihon Checklist. RESULTS In the 2020 and 2021 surveys, 17% and 19% of the participants exhibited oral frailty and experienced a fall in the previous year, respectively. Logistic regression analysis demonstrated that oral frailty (adjusted odds ratio: 1.553) and physical frailty as well as low levels of awareness of frailty were significant explanatory variables of the occurrence of fall incidents during the subsequent year. CONCLUSIONS Future studies are required to elucidate the mechanisms by which oral frailty induces fall incidents.

Hip Fractures in Elderly Individuals Did Not Decrease during the Coronavirus Disease 2019 Pandemic: Insights from the 2015 and 2020 Niigata Prefecture Fragility Hip Fracture Surveys. MEDICINA (KAUNAS, LITHUANIA) 2024; 60:573. [PMID: 38674219 PMCID: PMC11052488 DOI: 10.3390/medicina60040573] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/22/2024] [Revised: 03/27/2024] [Accepted: 03/28/2024] [Indexed: 04/28/2024]
Abstract
Background and Objectives: The incidence of osteoporotic hip fractures in Niigata Prefecture, Japan, has been studied approximately every 5 years since 1985. In 2020, as in previous surveys, a prefecture-wide survey was initiated as planned; however, the global outbreak of the coronavirus disease 2019 (COVID-19) began simultaneously. This study aimed to compare the results of the 2015 and 2020 Niigata Prefecture Fragility Hip Fracture Surveys to determine whether the COVID-19 pandemic affected the occurrence and treatment of proximal femoral fractures throughout Niigata Prefecture. Materials and Methods: In this study, data from the 2015 and 2020 Niigata Prefecture Fragility Hip Fracture Surveys were used. Data were obtained from registration forms returned by hospitals and clinics in Niigata Prefecture for patients living therein who were diagnosed with osteoporotic hip fractures over a 1-year period in 2015 and 2020. Results: In Niigata Prefecture, the total annual number of fractures increased from 3181 in 2015 to 3369 in 2020, whereas the age-adjusted fracture rate decreased. Regarding the location of the fractures, the proportion of outdoor fractures was lower than that of indoor fractures. The proportion of outdoor fractures decreased over the year as a whole, but in particular, the proportion of outdoor fractures decreased significantly under the issued emergency declarations. The most common reasons for delayed surgery related to COVID-19 were "waiting for PCR results" and "quarantine for fever," accounting for approximately 1.9% of all causes. Conclusions: In Niigata Prefecture, Japan, the effect of the COVID-19 pandemic on the number and rate of fractures was minuscule. The proportion of indoor fractures to outdoor fractures increased during the emergency declaration period. Considering that the number of fragility fractures remains the same during an infectious disease pandemic such as COVID-19, it is necessary to ensure that healthcare resources are available to deal with them.

Epidemiology of Osteoporosis in Patients with Chronic Obstructive Pulmonary Disease in Taiwan. J Epidemiol Glob Health 2024; 14:213-222. [PMID: 38353916 PMCID: PMC11043306 DOI: 10.1007/s44197-023-00183-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2023] [Accepted: 12/22/2023] [Indexed: 04/25/2024] Open
Abstract
BACKGROUND Chronic obstructive pulmonary disease (COPD) is a preventable and treatable chronic condition characterized by progressive, partially reversible airflow obstruction. Osteoporosis represents a significant comorbidity in individuals with COPD. However, the incidence and prevalence of osteoporosis among the COPD population remain unclear in Taiwan. Therefore, our objective is to investigate the incidence and prevalence of osteoporosis in patients with COPD. METHODS In this cross-sectional study, we enrolled a COPD population retrieved from the Taiwan National Health Insurance Research Database (NHIRD) spanning the years 2003 to 2016. Osteoporosis patients were identified using diagnosis codes. The study included newly diagnosed COPD patients from 2003 to 2016. The case group comprised patients who developed osteoporosis or osteoporotic fractures after their COPD diagnosis. We calculated the prevalence and incidence of osteoporosis in individuals with COPD and conducted trend tests. RESULTS A total of 1,297,579 COPD patients were identified during the period from 2003 to 2016, with 275,233 of them in the osteoporosis group. The average prevalence of osteoporosis among individuals with COPD was 21.21% from 2003 to 2016 in Taiwan. The number of osteoporosis cases increased from 6,727 in 2003 to 24,184 in 2016. The prevalence of osteoporosis among COPD patients increased from 3.62% in 2003 to 18.72% in 2016. The number of osteoporosis cases among individuals with COPD continued to rise over the years, reaching its highest point in 2016 with 24,184 new cases. The incidence of osteoporosis fluctuated during the study period but generally remained around 3,000 cases per 100,000 person-years. Notably, there was a significant upward trend in incidence from 2003 to 2006, after which the trend stabilized and remained relatively constant. CONCLUSIONS Our study highlights an increase in both the prevalence and incidence of osteoporosis in individuals with COPD. Given the significant medical, economic, and social implications associated with osteoporosis, a comprehensive and robust assessment of its healthcare burden can offer valuable insights for healthcare system planning and policymaking.

Sirtuins: exploring next-gen therapeutics in the pathogenesis osteoporosis and associated diseases. Immunopharmacol Immunotoxicol 2024:1-25. [PMID: 38318808 DOI: 10.1080/08923973.2024.2315418] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2023] [Accepted: 01/30/2024] [Indexed: 02/07/2024]
Abstract
OBJECTIVE Osteoporosis poses a substantial public health challenge due to an ageing population and the lack of adequate treatment options. The condition is marked by a reduction in bone mineral density, resulting in an elevated risk of fractures. The reduction in bone density and strength, as well as musculoskeletal issues that come with aging, present a significant challenge for individuals impacted by these conditions, as well as the healthcare system worldwide. METHODS Literature survey was conducted until May 2023 using databases such as Web of Science, PuMed, Scopus, and Google Scholar. RESULT Sirtuins 1-7 (SIRT1-SIRT7), which are a group of Nicotinamide adenine dinucleotide (NAD+)-dependent deacetylases, possess remarkable capabilities to increase lifespan and combat diseases related to aging. Research has demonstrated that these proteins play an important role in regular skeletal development and maintenance by directly impacting bone cells. Their dysfunction could be a factor in various bone conditions. Studies conducted on animals before clinical trials have shown that administering Sirtuins agonists to mice provides a safeguard against osteoporosis resulting from aging, menopause, and immobilization. These findings imply that Sirtuins may be a viable target for addressing the irregularity in bone remodeling and treating osteoporosis and other skeletal ailments. CONCLUSION The purpose of this review was to present a thorough and current evaluation of the existing knowledge on Sirtuins biology, with a particular emphasis on their involvement in maintaining bone homeostasis and contributing to osteoporosis. Additionally, the review examines potential pharmacological interventions targeting Sirtuins for the treatment of osteoporosis.

Genetic Prediction of Lifetime Risk of Fracture. J Clin Endocrinol Metab 2023; 108:e1403-e1412. [PMID: 37165700 DOI: 10.1210/clinem/dgad254] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/05/2023] [Revised: 04/15/2023] [Accepted: 05/09/2023] [Indexed: 05/12/2023]
Abstract
CONTEXT Fragility fracture is a significant public health problem because it is associated with increased mortality. We want to find out whether the risk of fracture can be predicted from the time of birth. OBJECTIVE To examine the association between a polygenic risk score (PRS) and lifetime fracture risk. METHODS This population-based prospective study involved 3515 community-dwelling individuals aged 60+ years who have been followed for up to 20 years. Femoral neck bone mineral density (BMD) was measured by dual-energy x-ray absorptiometry. A PRS was created by summing the weighted number of risk alleles for each single nucleotide polymorphism using BMD-associated coefficients. Fragility fractures were radiologically ascertained, whereas mortality was ascertained through a state registry. Residual lifetime risk of fracture (RLRF) was estimated by survival analysis. RESULTS The mortality-adjusted RLRF for women and men was 36% (95% CI, 34%-39%) and 21% (18%-24%), respectively. Individuals with PRS > 4.24 (median) had a greater risk (1.2-fold in women and 1.1-fold in men) than the population average risk. For hip fracture, the average RLRF was 10% (95% CI, 8%-12%) for women and ∼5% (3%-7%) for men; however, the risk was significantly increased by 1.5-fold and 1.3-fold for women and men with high PRS, respectively. CONCLUSION A genetic profiling of BMD-associated genetic variants is associated with the residual lifetime risk of fracture, suggesting the potential for incorporating the polygenic risk score in personalized fracture risk assessment.

Bone Cement Implantation Syndrome: A Rare Disaster Following Cemented Hip Arthroplasties-Clinical Considerations Supported by Case Studies. J Pers Med 2023; 13:1381. [PMID: 37763149 PMCID: PMC10532717 DOI: 10.3390/jpm13091381] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2023] [Revised: 09/08/2023] [Accepted: 09/13/2023] [Indexed: 09/29/2023] Open
Abstract
Severe symptoms such as hypoxemia, hypotension, and unexpected loss of consciousness may develop during surgical interventions that use polymethyl methacrylate (PMMA), or as it is commonly known, bone cement. Physicians recognize this amalgam of clinical manifestations more and more as a distinct entity that bears the name of bone cement implantation syndrome (BCIS). Trauma cases, especially hip fractures, are seen to have a higher incidence of developing this complication compared to orthopedic elective ones. This research aims to present a detailed description of six severe BCIS cases in order to raise awareness and to emphasize its importance. Five of them had fatal outcomes, which demonstrate the necessity of future research on this topic, as little is known about it presently. In the Discussion section, a narrative overview from the scientific literature is performed on potential risk factors, prevention measures, and management strategies. The experience gathered through this case series may aid medical staff in the development of diagnostic and therapeutic protocols, thus improving safety when cemented surgical techniques are used on a high-risk group of patients.

Surgical and Functional Outcomes of the Results of Conventional Two-Screw Proximal Femoral Nail (PFN) Versus Helical-Blade Anti-rotation Proximal Femoral Nail (PFNA2). Cureus 2023; 15:e43698. [PMID: 37724213 PMCID: PMC10505489 DOI: 10.7759/cureus.43698] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 08/18/2023] [Indexed: 09/20/2023] Open
Abstract
Introduction An intertrochanteric (IT) femur fracture is an extra-capsular fracture between greater and lesser trochanters. Unstable IT fractures are those where there is poor contact between fracture fragments (especially medial and posterior cortices), comminution, and fracture pattern, such that the weight-bearing forces tend to displace the fracture further or a reverse oblique type. Proximal femoral nailing (PFN) is one of the modalities for proximal femoral fractures. A newer modality for proximal femoral fracture is PFNA2, i.e., PFN anti-rotation, which makes use of a helical blade for a better compaction of bone. Both nail designs (PFN and PFNA2) are available in short and long sizes (so a total of four variants). Only a few studies have compared the treatment of IT femur fracture concerning fracture geometry, design, and length using either of the two nail types. In our study, we assessed the surgical and functional outcomes of PFN and PFNA2. Materials and methods This prospective observational study was carried out on 30 patients who had sustained IT fractures of the femur. All cases of IT femur fractures more than 18 years of age, closed injuries, and the patients who consented to participate in this program were included in the study. All open injuries, the patients who refused to participate in this program, patients who have associated injuries, patients with a subtrochanteric femur fracture, and patients with less than six months of follow-up were excluded. The patients were randomized into two types of implant groups. All patients were operated with a standard protocol. The study was conducted for 18 months from February 2021 to August 2022. The results were analyzed (of all four variants) by comparing patient demographics, implant size, implant type, locking methods, union time, and other parameters. Results Most of the patients were operated on with a 10 mm nail diameter (17/30 patients), 380 mm length (long-nail group) (five/11 patients), and 250 mm length (short-nail group). With the use of PFNA2, the overall duration of hospital stay was less. The overall operative time (incision to wound closure) with the use of the short PFNA2 was lesser than that with the use of other designs due to the use of the zig for distal screws. The use of a distal dynamic locking screw in a majority of the patients can get better compression at the fracture site once the patient starts weight bearing and decrease the chances of the Z-effect, reverse Z-effect, screw back-out, and screw cut-out. The union time was nearly the same in the majority of the patients, with an early union seen with the use of PFNA2 nails. The overall modified Harris hip score (HHS) at the final follow-up was nearly the same with slightly better results with the use of PFNA2. Conclusions PFNA2 is the implant of choice in elderly patients with osteoporotic bone. It has less operative time, which is required in such patients with medical comorbidities; hence, it has marginal superiority over PFN. Short-nail design results in less operative time and less blood loss.

The Role of BIA Analysis in Osteoporosis Risk Development: Hierarchical Clustering Approach. Diagnostics (Basel) 2023; 13:2292. [PMID: 37443685 DOI: 10.3390/diagnostics13132292] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2023] [Revised: 06/21/2023] [Accepted: 07/03/2023] [Indexed: 07/15/2023] Open
Abstract
Osteoporosis is a common musculoskeletal disorder among the elderly and a chronic condition which, like many other chronic conditions, requires long-term clinical management. It is caused by many factors, including lifestyle and obesity. Bioelectrical impedance analysis (BIA) is a method to estimate body composition based on a weak electric current flow through the body. The measured voltage is used to calculate body bioelectrical impedance, divided into resistance and reactance, which can be used to estimate body parameters such as total body water (TBW), fat-free mass (FFM), fat mass (FM), and muscle mass (MM). This study aims to find the tendency of osteoporosis in obese subjects, presenting a method based on hierarchical clustering, which, using BIA parameters, can group patients who show homogeneous characteristics. Grouping similar patients into clusters can be helpful in the field of medicine to identify disorders, pathologies, or more generally, characteristics of significant importance. Another added value of the clustering process is the possibility to define cluster prototypes, i.e., imaginary patients who represent models of "states", which can be used together with clustering results to identify subjects with similar characteristics in a classification context. The results show that hierarchical clustering is a method that can be used to provide the detection of states and, consequently, supply a more personalized medicine approach. In addition, this method allowed us to elect BIA as a potential prognostic and diagnostic instrument in osteoporosis risk development.

Increased incidence among the very elderly in the 2020 Niigata Prefecture Osteoporotic Hip Fracture Study. J Bone Miner Metab 2023:10.1007/s00774-023-01421-2. [PMID: 36947240 PMCID: PMC10031707 DOI: 10.1007/s00774-023-01421-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/04/2022] [Accepted: 03/13/2023] [Indexed: 03/23/2023]
Abstract
INTRODUCTION A 2015 study showed a decreasing trend in the incidence of osteoporotic hip fractures in Niigata Prefecture, Japan, which had been increasing. This study aimed to investigate the incidence of osteoporotic hip fractures in 2020, determine the long-term change in the incidence of hip fractures from 1985 to 2020, and assess whether the decline in fracture incidence since 2010 has continued. MATERIALS AND METHODS We obtained data from the registration forms submitted by hospitals and clinics of patients who lived in Niigata Prefecture and were diagnosed with osteoporotic hip fracture through a survey conducted from January 1, 2020 to December 31, 2020. RESULTS In 2020, 3,369 hip fractures were recorded in Niigata Prefecture. Although the overall incidence of age-specific hip fractures decreased, it increased in patients aged ≥ 90 years, regardless of sex. The proportion of patients receiving anti-osteoporosis drugs prior to hip fracture increased from 7.6% in 2004 to 17.3% in 2020. Notably, surgical treatment should be performed as early as possible, and the preoperative waiting time was 2.9 days, which was mainly due to holidays. CONCLUSION The incidence of hip fractures in Niigata Prefecture has gradually increased over the past 35 years, with an increasing change observed in the very elderly recently in 2020. Although the treatment of osteoporotic hip fractures in Niigata Prefecture is adequate, improvements may include increasing the rate of adoption of osteoporosis treatment further and decreasing the number of days of preoperative waiting.

Abstract
This study aims to determine the annual incidence of proximal femoral fractures in Italy in the period between 2001 and 2016 among older adults, and to describe the trends in the clinical management of these cases. Data were retrieved from the National Hospital Discharge records issued by the Italian Ministry of Health and from the Italian Institute for Statistics. The number of hospitalizations increased between 2001 and 2016, while the age-adjusted yearly incidence decreased from 832.2 per 100,000 individuals to 706.2. The median age was 83 years (IQR 78-88) with a large majority of females (76.6%). The type of fracture varied with age in female subjects, with older women more frequently reporting pertrochanteric fractures. Therapeutic strategies for the different types of fracture depended on patients' age. During the study years, improvements in fracture classification and management strategies were observed, with a clear decreasing trend for non-operative solutions. In conclusion, the number of proximal femur fractures in older adults is growing, even if at a lower rate compared to population aging. The Italian surgical practice changed during the study period towards the implementation of the most recent guidelines.

Fracture risk in Asian-Canadian women is significantly over-estimated by the Canadian Association of Radiologists-Osteoporosis Canada risk prediction tool: retrospective cohort study. Arch Osteoporos 2022; 17:133. [PMID: 36201065 DOI: 10.1007/s11657-022-01173-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/02/2022] [Accepted: 09/28/2022] [Indexed: 02/03/2023]
Abstract
Fracture risk calculators may not be accurate for all ethnicity groups. The Manitoba bone density registry was used to test the Canadian CAROC tool for predicting fracture risk in Asian-Canadian women. The tool significantly over-estimated fracture risk, suggesting that it may not be ideal for Asian-Canadian patients. PURPOSE Health risk prediction tools based on largely White populations may lead to treatment inequity when applied to non-White populations where outcome rates differ. We examined the calibration of the Canadian Association of Radiologists-Osteoporosis Canada (CAROC) fracture risk prediction tool in self-identified Asian-Canadian women. METHODS Retrospective cohort study of women over age 50 using the Manitoba BMD Registry. At first BMD, the intake questionnaire collected self-identification of ethnicity and fracture risk factors. 10-year fracture risk was estimated using CAROC and categorized into low, medium, or high fracture risk. Linked administrative databases identified incident osteoporotic fractures. Observed fracture rates were compared between White and Asian-Canadians and compared to the original CAROC risk stratification. RESULTS There were 63,632 and 1703 women who self-identified as White-Canadian or Asian-Canadian, respectively, covering approximately 600,000 patient-years follow-up. There were 6588 incident fractures; a similar percentage of patients were assigned to each risk stratum at baseline by CAROC. A progressive rise in 10-year observed fracture rates occurred for each CAROC stratum in the White-Canadian population but much lower fracture rates than predicted in Asian-Canadian patients (p < 0.001). Fracture incidence rate ratios were 1.9-2.6 fold higher in White- vs Asian-Canadian patients for all strata (p < 0.001). In the CAROC moderate and high-risk categories, observed fracture rates in Asian-Canadian patients were typically lower than predicted, indicating poor model calibration. CONCLUSION In Asian-Canadian women, observed osteoporosis fracture rates are lower than predicted when using the CAROC tool. Over-estimation of fracture risk may influence shared decision-making discussions.

Determinants of Lack of Recovery from Dependency and Walking Ability Six Months after Hip Fracture in a Population of People Aged 65 Years and Over. J Clin Med 2022; 11:jcm11154467. [PMID: 35956084 PMCID: PMC9369508 DOI: 10.3390/jcm11154467] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2022] [Revised: 07/22/2022] [Accepted: 07/27/2022] [Indexed: 01/27/2023] Open
Abstract
Background: Hip fracture in the elderly means that between a quarter and a half of patients do not regain the levels of independence and walking ability that they previously had, according to the literature, after the fracture. Material and methods: Retrospective study of 537 patients aged ≥65 years who survived at the sixth month after fracturing their hip, of which the age, sex, type of fracture, surgical risk, independence (BI), walking ability, cognitive level (PS), comorbidities, indicated drugs, complications, surgical delay, hospital stay, and surgical technique are known. Using Pearson’s χ2 test, all the variables were contrasted with respect to the limitation or not, at the sixth month of the recovery of both independence and pre-admission walking ability. Multivariate analysis provides the necessary adjustment to the previous contrast. Results: We have found that age and PS ≥ 5 at admission limit recovery from both dependency and walking ability. Surgical risk, independence (BI) upon admission, anemia, and constipation during the hospital stay limit the recovery of the BI. Worsening of walking ability during the hospital stay and the type of extra-articular fracture, which was surgically treated by osteosynthesis, limit the recovery of walking ability. Conclusions: The factors previously exposed, and perhaps the fact that patients with hip fractures are not routinely referred to rehabilitation, explain the high proportion of patients who do not recover their previous independency (36%) or walking ability (45%) to the fact of fracturing.

Effect of coordinator-based osteoporosis intervention on quality of life in patients with fragility fractures: a prospective randomized trial. Osteoporos Int 2022; 33:1445-1455. [PMID: 35195752 DOI: 10.1007/s00198-021-06279-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/16/2021] [Accepted: 12/17/2021] [Indexed: 10/19/2022]
Abstract
UNLABELLED We examined the effects of the coordinator-based intervention on quality of life (QOL) in the aftermath of a fragility fracture, as well as factors predictive of post-fracture QOL. The coordinator-based interventions mitigated the decrease in QOL. Secondary fracture after primary fracture, however, was a significant predictor of lower QOL. PURPOSE This study aimed to determine the effects of the coordinator-based intervention on QOL in the aftermath of a fragility fracture, as well as factors predictive of post-fracture QOL, in an Asian population. METHODS Patients with new fractures in the intervention group received the coordinator-based intervention by a designated nurse certified as a coordinator, within 3 months of injury. QOL was evaluated using the Japanese version of the EuroQol 5 Dimension 5 Level (EQ-5D-5L) scale before the fracture (through patient recollections) and at 0.5, 1, and 2 years after the primary fracture. RESULTS Data for 141 patients were analyzed: 70 in the liaison intervention (LI) group and 71 in the non-LI group. Significant intervention effects on QOL were observed at 6 months after the fracture; the QOL score was 0.079 points higher in the LI group than in the non-LI group (p=0.019). Further, the LI group reported significantly less pain/discomfort at 2 years after the fracture, compared to the non-LI group (p=0.037). In addition, secondary fractures were found to significantly prevent improvement and maintenance of QOL during the recovery period (p=0.015). CONCLUSION Short-term intervention effects were observable 6 months after the primary fracture, with the LI group mitigated the decrease in QOL. Few patients in the LI group reported pain/discomfort 2 years after the fracture, but there is uncertainty regarding its clinical significance. Secondary fracture after initial injury was a significant predictor of lower QOL after a fracture.

Abstract
With improved life expectancy and ever-increasing geriatric population with concomitant osteoporosis, there is increase in osteoporotic intertrochanteric hip fractures. Even the best surgical advances fail to provide satisfactory and early results. As a result, researchers' focus has lately shifted to developing a more integrated approach that combines the pharmacotherapeutic capabilities of teriparatide, a recombinant version of human parathyroid hormone (1-34), a new anabolic drug that enhances bone mass and strength by promoting osteoblastic activity and hastens fracture union in both human and animals. We attempted to evaluate the therapeutic efficiency of teriparatide therapy on outcomes of surgically managed Intertrochanteric hip fractures in osteoporotic patients. A total of 31 patients with established osteoporosis and Intertrochanteric fractures were selected and divided into two groups, managed surgically with proximal femur nailing, and then prospectively compared with one group receiving teriparatide therapy in addition to standard treatment after taking necessary consent and allocation into two groups based on the preference of patients to take additional teriparatide or not after understanding the benefits and risks involved. We aimed to assess the functional and radiological effects of teriparatide on bone mineral density, the time taken for fracture union, and other fracture-related postoperative complications such as weight bearing and residual bone pain. All patients were followed up at 6, 12, and 24 weeks. Time to fracture union was significantly shortened, with considerable improvement in bone density and functional outcome in the teriparatide group. Varus collapse, the rate of migration of the helical blade, and shortening of the femoral neck were also significantly less in the study group. From the assembled data, we can safely assume that with early union rates with better functional improvement with additional advantage of increased bone mass, we favor supplemental teriparatide therapy in the management of osteoporotic patients with femoral intertrochanteric fractures to augment healing. Further studies with a larger sample size are required to support our observation.

Bone regeneration: A message from clinical medicine and basic science. Clin Anat 2022; 35:808-819. [PMID: 35654609 DOI: 10.1002/ca.23917] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2022] [Accepted: 05/27/2022] [Indexed: 11/08/2022]
Abstract
Population aging is a global phenomenon and with it, the number of bone fractures increases due to higher incidences of osteoporosis. Bone fractures in the elderly increase the risk of bedridden status and mortality. Therefore, the control of osteoporosis and bone fracture is important for healthy life expectancy, and the fundamental understanding of its pathogenesis and its application in treatment is of great social significance. To solve these clinical problems, it is necessary to integrate clinical medicine and basic research. Bone regeneration after a fracture is an essential function of the living body. The prevailing view is that a small number of resident skeletal stem cells are solely responsible for regenerative capacity. Although these cells have long been considered to be in the bone marrow, it has been shown that they are also present in the growth plate and periosteum. More recently, distinct types of cells in the bone marrow, including bone marrow stromal cells, osteoblast progenitor cells, and osteoblasts, have been shown to participate in bone regeneration. Interestingly, the cellular plasticity of differentiated cells, rather than active recruitment of resident stem cell populations, may largely account for regeneration of bone tissues; terminally differentiated cells de-differentiate into a stem cell-like state, and then re-differentiate into regenerating bone. In this review, we discuss the clinical risk and preventive therapy of bone fractures and the current concept of bone regeneration in basic mechanical insights, which may prove useful to both clinicians and researchers.

30-year trends of hip and vertebral fracture incidence in Japan: a systematic review and meta-analysis. J Bone Miner Metab 2022; 40:327-336. [PMID: 35059889 DOI: 10.1007/s00774-021-01288-1] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/01/2021] [Accepted: 11/03/2021] [Indexed: 02/06/2023]
Abstract
INTRODUCTION A previous review study showed the trends of declining age- and sex-adjusted incidence of hip fractures in almost all the countries, except Austria and Japan, in the most recent of the periods studied. However, the expansion of devices for diagnosis and drugs for fracture prevention in Japan was roughly the same as in the other countries. This study aimed to conduct a comprehensive systematic review and meta-analyses of incidence rates (IRs) of osteoporotic fractures reported over 30-years in multiple communities in Japan and to evaluate secular trends. MATERIALS AND METHODS We searched MEDLINE for observational studies reporting IRs of osteoporotic fractures in the general population. Additional studies were identified by hand searches of reference lists of published studies. Two reviewers and 1 expert independently assessed study eligibility. Pooled analyses of IRs were conducted by a random-effect model. Data from 3 periods (1985-1999, 2000-2009, and from 2010) were compared. RESULTS Of 47 eligible studies, 21 with IRs or information enabling recalculation of IRs in the population aged 50 years and older were included. IRs of hip fractures per 100,000 person-years significantly increased over time in men: 1985-1999, 0.79 (95% CI 0.71-0.87); 2000-2009, 1.18 (95% CI 1.09-1.28); and 2010 onwards, 1.31 (95% CI 1.17-1.45). They also significantly increased in women: 2.23 (95% CI 1.89-2.58); 3.99 (95% CI 3.70-4.28); and 4.39 (95% CI 4.00-4.78), respectively. CONCLUSION IRs of hip fractures continuously increased in the past 30-years in men and women despite improved the diagnosis, treatment, and care. Such data from Japan, a leading aging society, provide important information for other countries.

Decennial trends in hip fractures over 20 years in Yamagata Prefecture, Japan. J Orthop Sci 2022; 28:621-626. [PMID: 35101339 DOI: 10.1016/j.jos.2022.01.001] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/10/2021] [Revised: 12/10/2021] [Accepted: 01/03/2022] [Indexed: 11/28/2022]
Abstract
BACKGROUND Hip fracture is among the most common injuries in elderly people. We aimed to investigate the decennial trends in hip fractures in patients ≥65 years of age. METHODS A questionnaire was distributed to all hospitals with a Department of Orthopaedic Surgery in Yamagata Prefecture to collect data on hip fractures occurring in 1996, 2006 and 2016. RESULTS The response rate was 100%. The total numbers of hip fractures in 1996, 2006 and 2016 were 665, 1169 and 1,728, respectively (crude incidence: 258, 373 and 494 per 100,000 person-year, respectively). Injuries frequently occurred in the early morning and daytime morning in 1996. In contrast, they frequently occurred in activity times (e.g., morning and afternoon) in 2006 and 2016. Among the patients, 80-90% were injured by simple falls, and 70-80% were injured indoors. The incidence of trochanteric fractures was approximately 1.8-1.9 times greater than incidence of neck fractures in all years. Especially, trochanteric fractures in females of ≥90 years of age markedly increased. The rate of surgical treatment was the same in 1996 and 2006, but was lower in 2016. In 1996, the percentage of independent walkers at discharge and 1 year later was almost the same. In 2006 and 2016, the rate of independent walkers was low at discharge, but increased 1 year later. The rate of discharge to home decreased gradually. The combined percentage of patients discharged to home and to rehabilitation institutions in 2006 and the percentage of patients who entered the regional referral clinical pathway in 2016 were both approximately 70%, with no marked changes observed. CONCLUSIONS Hip fractures, especially trochanteric fractures in super-aged females, increased. Discharge to home decreased, and the use of the regional referral clinical pathway was widespread. Ambulation ability was reduced at discharge, but improved after 1 year.

Association between Neutrophil Levels on Admission and All-Cause Mortality in Geriatric Patients with Hip Fractures: A Prospective Cohort Study of 2,589 Patients. Int J Clin Pract 2022; 2022:1174521. [PMID: 36628151 PMCID: PMC9797311 DOI: 10.1155/2022/1174521] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/21/2022] [Revised: 12/06/2022] [Accepted: 12/10/2022] [Indexed: 12/24/2022] Open
Abstract
OBJECTIVE To evaluate the association between neutrophil levels and all-cause mortality in geriatric hip fractures. METHODS Elderly patients with hip fractures were screened between January 2015 and September 2019. Demographic and clinical characteristics of the patients were collected. Linear and nonlinear multivariate Cox regression models were used to identify the association between neutrophil levels and mortality. Analyses were performed using Empower Stats and R software. RESULTS A total of 2,589 patients were included in this study. The mean follow-up period was 38.95 months. During the study period, 875 (33.80%) patients died due to various causes. Linear multivariate Cox regression models showed that neutrophil levels were associated with mortality after adjusting for confounding factors, when neutrophil concentration increased by 1∗109/L, the mortality risk increased by 3% (HR = 1.03, 95% CI: 1.00-1.06, and P=0210). Neutrophil concentration was used as a categorical variable; we only found statistically significant differences when neutrophil levels were high (HR = 1.27, 95% CI:1.05-1.52, and P=0.0122). In addition, the results are stable in P for trend and propensity score matching sensitivity analysis. CONCLUSIONS Neutrophil levels are associated with mortality in geriatric hip fractures and could be considered a predictor of death risk in the long-term. This study is registered with the Chinese Clinical Trial Registry (ChiCTR) as number ChiCTR2200057323.

Abstract
BACKGROUND Intertrochanteric fractures can be treated, both by conservative and operative methods depending upon the status of the patient. The purpose of this study was to assess the functional outcome of intertrochanteric fracture of femur treated with dynamic hip screw (DHS) with de-rotation screw comparing and proximal femoral nail (PFN). METHODOLOGY We compared 30 (male: 23, female: seven) cases of intertrochanteric fractures with a mean age of the population was 65 years and male to female ratio in was 2.75:1. Patients were recruited in this study having inclusion criteria of adults above 50 years of age, isolated intertrochanteric fractures of the AO Foundation/Orthopaedic Trauma Association (AO/OTA) type A1 and A2, fracture less than two weeks, and intertrochanteric fracture with or without distal extension. RESULTS Post-operatively, patients treated by either of these two methods were statistically analyzed in terms of comparing advantages and disadvantages in terms of the time of fracture union and outcome of both above-mentioned procedures using Harris hip score. CONCLUSION PFN gives better results than DHS with De-Rotation Screw-in intertrochanteric fractures in terms of the amount of blood loss during surgery, duration of surgery, early toe-touch weight-bearing, and Harris hip scores. There is no difference between the two modalities in terms of duration of hospitalization, fracture union, mortality and morbidity, and postoperative complications.

Effect of nutritional status before femoral neck fracture surgery on postoperative outcomes: a retrospective study. BMC Musculoskelet Disord 2021; 22:1027. [PMID: 34879851 PMCID: PMC8656010 DOI: 10.1186/s12891-021-04913-2] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/13/2021] [Accepted: 11/24/2021] [Indexed: 12/14/2022] Open
Abstract
Background Although nutritional status is crucial in gait recovery after femoral neck fracture surgery, the relationship between preoperative nutritional status and postoperative outcomes remains unknown. This study examined the effects of preoperative nutritional status on postoperative outcomes in patients undergoing femoral neck fracture surgery. Methods Data regarding the joints of 137 patients (29 men, 108 women) who underwent bipolar hemiarthroplasty for femoral neck fractures at our hospital from January 2015 to December 2019 were retrospectively examined. The Geriatric Nutritional Risk Index (GNRI), an index of nutritional status, was used to classify patients into two groups: a normal group (GNRI ≥92; n = 62) and an undernourished group (GNRI < 92; n = 75). The study endpoints included age at surgery, sex, Mini Mental State Examination (MMSE), American Society of Anesthesiologists Physical Status (ASA) classification, preoperative waiting period, intraoperative blood loss, surgery time, perioperative hemoglobin levels, blood transfusion rate, complication rate, 6-month mortality rate, transfer rate, percentage of patients unable to walk at discharge or transfer, and inability to walk 6 months postoperatively. Results The patients in the undernourished group was significantly older at surgery (p < 0.01) and had a lower perioperative hemoglobin levels (p < 0.01), a higher blood transfusion rate (p < 0.01), a lower MMSE (p < 0.01), a longer preoperative waiting period (p < 0.05), a higher transfer rate (p < 0.05), were more likely to be unable to walk 6 months postoperatively (p < 0.01), a higher complication rate (p < 0.05), and a higher 6-month mortality rate (p < 0.01) than the normal group. Patients in the undernourished group had worse rates of postoperative complications, transfer, mortality, and inability to walk 6-month after surgery than those in the normal group. Conclusions A poor nutritional status affects the gait function and systemic condition of patients undergoing femoral neck fracture surgery; therefore, early nutritional interventions may reduce mortality rates and shorten rehabilitation. These results suggest that the GNRI effectively predicts postoperative complications, mortality, and gait function.

Estimating the future clinical and economic benefits of improving osteoporosis diagnosis and treatment among women in Japan: a simulation projection model from 2020 to 2040. Arch Osteoporos 2021; 16:156.

Abstract
UNLABELLED Impact of increased osteoporosis diagnosis and treatment among postmenopausal women (PMW) on reduction in fractures and associated costs in Japan from 2020 to 2040 was modeled. INTRODUCTION Japan is currently home to the world's oldest population and the 65 + years demographic is expected to grow to 35% by 2040. Thus, identifying strategies to reduce clinical and economic burden associated with osteoporosis among this at-risk population is critical. METHODS A microsimulation model was developed to project osteoporotic annual fracture incidence and costs among PMW 2020-2040. Fracture risk was estimated using a simplified Fracture Risk Assessment Tool (FRAX). Fracture estimates were based on annualized FRAX risk and treatment impact. Published literature informed inputs for direct and indirect fracture costs, DXA screening costs, and treatment costs and efficacy. Japan's current screening and treatment rates were compared against 50% increases to (1) case finding (screening rate and subsequent treatment rate) and (2) treatment rate among those at highest fracture risk. RESULTS From 2020 to 2040, 21.6 million fractures are projected costing US $410.2 billion. Increased case finding scenario resulted in the prevention of 456.9 thousand primary and 340.9 thousand second + fractures saving US $4.25 billion. Increased treatment scenario led to 500.5 thousand and 435.5 thousand fewer primary and second + fractures, respectively, and reduced economic burden by $3.1 billion. CONCLUSION Improvements to rates of osteoporosis screening and preventive treatment in Japan's aging population through disease awareness campaigns and post-fracture care programs, among others, will likely reduce osteoporosis-associated clinical and economic burden.

Abstract
UNLABELLED This study assessed the cost effectiveness of romosozumab versus teriparatide, both sequenced to alendronate, for the treatment of severe postmenopausal osteoporosis in Japan, using bone mineral density (BMD) efficacy data. Results show that romosozumab/alendronate produces greater health benefits at a lower cost than teriparatide/alendronate. INTRODUCTION This study aims to assess the cost effectiveness of romosozumab versus teriparatide, both sequenced to alendronate, for the treatment of severe postmenopausal osteoporosis in Japanese women previously treated with bisphosphonates. METHODS A Markov model was used to assess the relative cost effectiveness of 1 year of romosozumab versus 2 years of teriparatide, both sequenced to alendronate for a total treatment duration of 5 years. Outcomes for a cohort of women with a mean age of 78 years, a T-score ≤-2.5 and a previous fragility fracture were simulated over a lifetime horizon. The analysis was conducted from the perspective of the Japanese healthcare system and used a discount rate of 2% per annum. To inform relative fracture incidence, the bone mineral density (BMD) advantage of romosozumab over teriparatide was translated into relative risks of fracture, using relationships provided by a meta-regression of osteoporosis therapy trials. Outcomes were assessed in terms of lifetime costs (2020 US dollars) and quality-adjusted life years (QALYs). RESULTS Base case results showed that, compared with teriparatide/alendronate, romosozumab/alendronate reduced costs by $5134 per patient and yielded 0.045 additional QALYs. Scenario analyses and probabilistic sensitivity analysis confirmed that results are robust to uncertainty in model assumptions and inputs. CONCLUSION Results show that romosozumab/alendronate produces greater health benefits at a lower total cost than teriparatide/alendronate.

Abstract
AIMS Accurate epidemiological hip fracture data is essential for healthcare planning and targeted prevention strategies. Limited reports of hip fracture incidence rates in the Republic of Ireland (ROI) exist. The aim is to calculate the current age- and gender-specific incidence of hip fractures in a level 1 Trauma Centre in the ROI, and the difference in these rates over a 10 year period. MATERIALS AND METHODS This was a retrospective, population-based, observational study. The local Hospital In-Patient Enquiry (HIPE) database was used to generate data for analysis; capturing all patients admitted for hip fracture in three time periods over 10 years. Patients < 55 years old, pathological fractures, and periprosthetic fractures were excluded. Age- and gender-specific incidence rate was calculated using HIPE and national census data. RESULTS Absolute number of hip fractures rose by 8.5% between 2008/09 (n = 800) and 2018/19 (n = 868) time periods. Cervical hip fractures dominated in all 3 time periods. The average age of patients remained at 80 years but length of stay for patients was reduced by 16% 5 years later and by 21% 10 years later from the initial study point. Both the entire and susceptible (> 55 years) population numbers increased by 13% and 30%, respectively, yet overall hip fracture incidence rate declined 10 years on. Hip fracture incidence rate in the entire population fell by 3.23 per 100,000 population, and by 65.11 per 100,000 population in the susceptible population. The majority of both male and female age groups exhibited declining annual incidence rates over the 10 year study period. CONCLUSION Results are consistent with the global experience of declining overall incidence rate of hip fractures, despite rising susceptible population numbers. This report adds to the sparse hip fracture incidence data available in the ROI which can be applied in future healthcare planning strategies.

Abstract
The increase in the incidence of hip fractures over time disappeared in Northern European and North American Caucasians after 2000, while an increase was observed in Asian countries including Japan until 2010. However, a decrease in the incidence was observed after 2010. The prevalence of vertebral fractures in Asians, Europeans, and American Caucasians is similar, and the incidences of clinical and morphometric vertebral fractures are higher in Asians compared with European Caucasians. The decrease in the incidence of vertebral fractures over time has been observed in Japan. Although the stabilization or decrease over time in the incidence of hip and vertebral fractures have been observed, the number of patients with these fractures is expected to increase rapidly with increases in the elderly population. Multidisciplinary measures to prevent fragility fractures are an urgent issue in Asia at this time. This narrative review outlines the recent trends in incidence and future burdens of hip fracture and vertebral fracture in Asia.

Abstract
UNLABELLED We investigated the relationship between serum 25(OH)D levels, grip strength, and fall score in elderly osteoporotic women for fall risk assessment. Both low serum 25(OH)D and low grip strength were independently associated with increased fall risk. The serum 25(OH)D cutoff specific to increased fall risk was 14 mg/dL (35 nmol/L). PURPOSE This study aimed to establish a cutoff value of serum 25-hydroxyvitamin D (25(OH)D) for fall assessment and investigate the relationship between serum 25(OH)D, grip strength, and fall score adjusted for age in osteoporotic elderly Japanese women. METHODS This is a cross-sectional study utilizing collected data of osteoporotic elderly (age ≥65 years) female patients. A questionnaire for fall risk assessment was used, in which a score ≥ 6 was determined as increased fall risk. Serum 25(OH)D levels and grip strength were measured, and the cutoff points were calculated by receiver operating curve (ROC) analysis. Logistic regression analysis with age adjustment was conducted for potential risk factors for fall. RESULTS After applying eligibility criteria, finally, 349 patients were enrolled. The median patient age was 77.0 years, and the mean serum 25(OH)D level was 15.6 ng/mL (36 nmol/L). Based on the ROC analysis, we defined the cutoff values of serum 25(OH)D level and grip strength as 14 ng/mL (35 nmol/L) and 15 kg, respectively. A multivariate analysis adjusted for age was conducted. Low serum 25(OH)D level and grip strength were independent risk factors for ≥6 fall risk scores. CONCLUSION Both low serum 25(OH)D level and low grip strength were independently associated with increased fall risk score in osteoporotic elderly women. The appropriate serum 25(OH)D cutoff specific to the increased fall risk group in this population was 14 mg/dL (35 nmol/L). These findings might be used for the identification of patients with high fall risks. These results should be confirmed in other patient groups.

Abstract
OBJECTIVES This study aimed to investigate the prevalence of patients with rheumatoid arthritis (RA) at a high risk of major osteoporosis (OP)-related fractures and the status of OP-related medical treatment for these patients. METHODS We enrolled 120 patients aged ≥40 years (average, 69.1 years) with RA. The Fracture Risk Assessment Tool (FRAX®) was used to evaluate the fracture risk. Of the 120 patients, the femoral neck bone mineral density (BMD) was evaluated in 102 patients, and their FRAX® scores were calculated alongside the BMD values. Patients observed to be at a high risk of a major OP-related fracture (10-year probability >20% or hip fracture risk >3%), according to FRAX®, were identified as those requiring OP treatment; medication ratio for OP (percentage of patients actually receiving medication among patients requiring OP treatment) was assessed. RESULTS OP treatment was indicated in 75 (63%) patients; the medication ratio for OP was 49%. The use of biological disease-modifying anti-rheumatic drugs and corticosteroids showed a positive effect; however, the use of methotrexate showed a negative effect on the medication ratio. CONCLUSION The number of potential patients requiring OP treatment is underestimated. All patients with RA should be assessed to determine their eligibility for OP treatment.

Abstract
The aging of the Korean population is expected to result in an increase in the prevalence of hip fractures. The aim of this review is to evaluate potential hip-fracture trends in Korea during the last few decades. Data from a hip fracture-related epidemiology study informed by: (1) a cohort study; (2) hospital-based cohort study; and (3) claims database, were reviewed and summarized. The incidence of hip fractures rose from 159.1/100,000 in 2008 to 181.5/100,000 in 2012, and the total number of hip fractures is estimated to increase by 1.4 times over the next 10 years (35,729 in 2016 to 51,259 in 2025). The use of intramedullary nails has greatly surpassed the use of plates for the treatment of intertrochanteric fractures. The 1-year cumulative mortality rates in patients aged ≥50 years after hip fractures based on National Health Insurance Service data were 17.2% (3,575/20,849) in 2008 and 16.0% (4,547/28,426) in 2012; the decrease was mainly observed among women. In addition, the mean 1-year mortality rates were 21% for men and 15% for women, indicating that mortality was 1.4 times higher in men than in women. The number of hip fractures is rapidly increasing, and the incidence of hip fractures demonstrated a slightly increasing trend until 2012. Trends in the use of varying surgical options for treatments for femoral neck and intertrochanteric fractures follow global trends. Although the high mortality rate after hip fractures in Korea remains concerning, a decrease in these rates over the study period was observed.

Elevated Lateral Position Improves the Success of Paramedian Approach Subarachnoid Puncture in Spinal Anesthesia before Hip Fracture Surgery in Elderly Patients: A Randomized Controlled Study. Med Sci Monit 2020; 26:e923813. [PMID: 32759888 PMCID: PMC7431383 DOI: 10.12659/msm.923813] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 01/13/2023] Open
Abstract
Background The aim of this study was to determine whether an elevated lateral recumbent position, compared to regular lateral recumbent position, may reduce the number of needle passes and attempts required for success subarachnoid puncture in spinal aesthesia before surgery in elderly patients with hip fractures. Material/Methods This was a randomized controlled interventional study in Beijing Jishuitan Hospital. Patients older than 65 years of age with hip fracture orthopedics who were planned to receive subarachnoid block in the lateral recumbent position before surgery were enrolled. The eligible patients were randomly allocated into the experimental group, in which a lateral recumbent position with head and chest elevated 30° was taken during subarachnoid puncture. In the control group, subarachnoid puncture was performed in the lateral recumbent position. The main outcome was the numbers of needle passes required for a success puncture. Other outcomes included success rate in different numbers of attempts, patients reported discomfort score, and complications. Results A total of 90 patients were enrolled, with 45 patients in each group. The number of needle passes (2.00 versus 3.00, P=0.001) and the number of attempts (1.00 versus 2.00, P<0.001) required for a successful subarachnoid puncture were significantly less in the experimental group than in the control group. Patients in the experimental group also had lower discomfort scores. The procedure process, including overall times needed for puncture, anesthesia, and surgery did not show differences between the 2 groups. Complications were few and similar between the 2 groups. Conclusions An elevated lateral recumbent position during the subarachnoid puncture in spinal anesthesia significantly reduced the needle pass numbers needed for success dural puncture, and reduced discomfort in elderly patients with hip fractures.

Abstract
Osteoporotic hip fracture is a major public health issue. Estimation of the outcome and maximization of functional recovery after fracture is very important in the treatment of older patients. The purposes of this study were to clarify the functional outcomes after the treatment of hip fracture and to identify the factors that influence functional recovery. In the present study, 228 patients admitted to an acute-care hospital from January 2016 to June 2018 were evaluated. The patients were categorized into a trochanteric fracture group (n = 128) and a neck fracture group (n = 100). We retrospectively reviewed their ambulation ability 6 months after fracture using the Functional Ambulation Category (FAC) score. The other survey items were the presurgical duration, length of hospital stay, time until beginning to walk using parallel bars, complications affecting treatment, and mortality rate. The 6-month follow-up rate was 54.4% (n = 124). The results showed that the patients with trochanteric fracture were significantly older than those with neck fracture (86 vs. 82 years, respectively; p = 0.03). In total, 85.0% of patients with trochanteric fracture and 92.2% of patients with neck fracture were independent ambulators before injury (FAC score of 4 or 5). The FAC score 6 months after fracture was positively correlated with the FAC score before fracture and at discharge (all p<0.001) and negatively correlated with patient age (p<0.001) and presurgical duration for patients with neck fracture (p = 0.04). There was no statistically significant correlation with the length of hospital stay or the time until beginning to walk using parallel bars. In conclusion, patients with trochanteric fractures were older than those with neck fractures. In both fracture types, walking recovery 6 months after hip fracture was related to the FAC score before injury and at discharge from an acute-care hospital but not to the time until beginning to walk using parallel bars.

Hip fractures in the elderly Chilean population: a projection for 2030. Arch Osteoporos 2020; 15:116. [PMID: 32720199 DOI: 10.1007/s11657-020-00794-5] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/26/2020] [Accepted: 07/21/2020] [Indexed: 02/03/2023]
Abstract
UNLABELLED Using national databases, we projected the magnitude of hip fractures among the elderly Chilean population by 2030. Hip fractures will increase by 27.5% from 2018 to 9862 cases (95% CI = 8760 to 10,965). The most substantial growth is expected to occur in patients older than 80 years of age. INTRODUCTION There is scarce information regarding the magnitude of hip fractures that will be observed in Latin American countries in the near future. The aim of this study is to project the volume of hip fractures in the elderly Chilean population by the year 2030. METHODS The database of the Chilean Department of Statistics and Health Information, which includes all hospital discharges within Chile, was employed to evaluate the volume of hip fractures observed from 2012 to 2018 in the elderly population (≥ 65 years old). The annual incidence was determined by combining the volume of fractures with census data. Linear regression analysis was performed to determine the projected volume of hip fractures for 2030. RESULTS For 2030, hip fractures among the elderly population are projected to grow 27.5% (R2 = 0.92) to 9862 cases (95% CI = 8760 to 10,965). In the group from 65 to 79 years old, hip fractures are expected to grow 21.6% (R2 = 0.87) to 3046 cases (95% CI = 2686 to 3405). In patients ≥ 80 years of age, hip fractures are expected to grow 30.1% (R2 = 0.9) to 6817 cases (95% CI = 5889 to 7744). CONCLUSIONS A substantial growth in the volume of hip fractures is expected for the next decade among the elderly Chilean population, especially in patients ≥ 80 years of age. A national healthcare strategy should consider efforts to mitigate the impact of the future burden related to patients' care.

Big Data-Driven Determinants of Length of Stay for Patients with Hip Fracture. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17144949. [PMID: 32659953 PMCID: PMC7400185 DOI: 10.3390/ijerph17144949] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/16/2020] [Revised: 07/03/2020] [Accepted: 07/07/2020] [Indexed: 12/13/2022]
Abstract
It is important that length of stay (LOS) management for alleviating health care financial burdens and improving patient outcomes. The aim of this study was to report the differences of LOS and the factors affecting LOS of hip fracture patients using big data. A total of 463,194 data were collected from 2016 to 2017 KNHDS. Of those, 2238 patients with the hip fracture primary diagnosis were included in the study population. As independent variables were used gender, age, type of insurance, admission route, result of treatment, number of hospital beds, the presence of surgery, and comorbidities. Statistical analysis performed using the IBM SPSS Statistics for Windows, version 25.0. A statistically significant difference was observed in the length of stay of hip fracture patients according to the healthcare insurance type. The difference in LOS associated with comorbidities was statistically significant for hypertension, peptic ulcer disease, coagulopathy, and alcohol abuse (p < 0.05). Independent variables that affected LOS of hip fracture patients with national health insurance were the treatment result, operation presence, comorbidity count, and hospital beds (p < 0.001). The factors associated with the length of stay for hip fracture patients were the difference according to the healthcare insurance type. The results of this study can be used as a basic data for the national health policy for the proper distribution and utilization of medical resources.

Abstract
Hip fractures are of great interest worldwide as the geriatric population continues to increase rapidly. Currently, surgeons prefer to use cephalomedullary nail for internal fixation of pertrochanteric/intertrochanteric fractures. This article summarizes 10 concepts in hip fracture treatment over the past 20 years, including fracture line mapping, proximal lateral wall and anterior cortex, posteromedial lesser trochanter-calcar fragment, anteromedial cortex support reduction, changes of fracture reduction after sliding and secondary stability, nail entry point and wedge-open deformity, tip-apex distance and calcar-referenced tip-apex distance, femoral anterior bowing and nail modification, long nails for wide medullary canal and large posterior coronal fragment, and postoperative stability score.

Recent trends in the incidence of hip fracture in Tottori Prefecture, Japan: changes over 32 years. Arch Osteoporos 2020; 15:152. [PMID: 33006016 PMCID: PMC7529614 DOI: 10.1007/s11657-020-00823-3] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/26/2020] [Accepted: 09/15/2020] [Indexed: 02/03/2023]
Abstract
UNLABELLED The incidence rate of hip fracture in Tottori Prefecture tended to increase until 2018 in men, but it did not increase after 2010 in women. By type of fracture, the incidence rate of femoral neck fractures also increased over time in men, but no other changes were observed from 2010. PURPOSE The aims of this study were to determine the sex-, age-, and fracture-type-specific incidence rates of hip fractures in Tottori Prefecture between 2007 and 2018 and to compare the results with our past results to identify changes over time. METHODS All hip fractures in people aged 35 years or older living in Tottori Prefecture were surveyed from 2007 to 2018 throughout the entire prefecture, and the age- and sex-specific incidence rates were calculated. The incidence rates from 1986 to 1988, 1992 to 1994, 1998 to 2000, and 2004 to 2006 previously reported were used for the analysis. RESULTS In men, the age-adjusted number of patients adjusted by demographic structure based on the mean incidence rate for each 3-year period from 1986 to 2018 showed an increase in incidence over time compared with the incidence for 1986-1988 (p < 0.001). In women, the incidence rose over time compared with the incidence for 1986-1988 until 2004-2006 (p < 0.001), and no further increase was observed from 2010. The age-specific incidence rates of neck fracture in men were higher in 2010-2012 and 2016-2018 compared with 2004-2006 (p < 0.001), but those in women showed no increase with time. Those of trochanteric fracture did not change over time in either men or women. CONCLUSION The hip fracture incidence rate in Tottori Prefecture, Japan, tended to increase until 2018 in men, but it did not increase after 2010 in women.

Secular trends in major osteoporotic fractures among 50+ adults in Denmark between 1995 and 2010. Osteoporos Int 2019; 30:2217-2223. [PMID: 31418061 PMCID: PMC6811370 DOI: 10.1007/s00198-019-05109-0] [Citation(s) in RCA: 23] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/27/2018] [Accepted: 08/09/2018] [Indexed: 12/16/2022]
Abstract
UNLABELLED We investigated the incidence trend in all major osteoporotic fractures for the whole country of Denmark between 1995 and 2010. Hip and other osteoporotic fractures declined for the general population and especially among women. But, we observed some increasing trend among men which needs more attention. PURPOSE The trend in osteoporotic fractures is varied across the globe, and there is no updated information in the case of Denmark for all major osteoporotic fractures (MOF). Thus, we investigated the incidence rates (IRs) of MOF among 50+ adults in Denmark over the period 1995-2010. METHODS A series of cross-sectional analyses was done using the Danish National Health Service Register. Participants were 50+ adults in the full country Denmark with a MOF between 1995 and 2010. Gender- specific IRs of MOF per 10,000 person years (PYs) were estimated, in addition to IRs of individual fracture sites (hip, vertebrae, humerus, and radius/ulna), and women-to-men IR ratios for MOF. RESULTS A general decline was observed in IRs of MOF for the whole population (from 169.8 per 10,000 PYs in 1995, to 148.0 in 2010), which was more pronounced among women. Thirty-one and nineteen percent of decline was observed in hip fracture rates among women and men, respectively. The trend in clinical vertebral fracture was slightly decreasing for women and increasing for men. The women-to-men rate ratio of MOF decreased noticeably from 2.93 to 2.72 during study period. CONCLUSIONS We observed declining trends in MOF and hip fracture for both sexes. However, a lower rate of decrease of hip fracture and an increasing trend in vertebral fracture was noticed among men. Considering our observations and the major economic burden that accompanies this devastating disease, more attention should be paid to MOF, especially in men.

Relationship Between Gliding and Lateral Femoral Pain in Patients With Trochanteric Fracture. Arch Phys Med Rehabil 2019; 101:457-463. [PMID: 31647900 DOI: 10.1016/j.apmr.2019.09.011] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2019] [Revised: 09/20/2019] [Accepted: 09/20/2019] [Indexed: 11/23/2022]
Abstract
OBJECTIVE To investigate the association between gliding and lateral femoral pain with trochanteric fracture (TF). DESIGN Prospective cohort study. SETTING The survey was conducted at approximately 3 weeks and 11 weeks post operation. PARTICIPANTS Patients (N=23) with TF after surgery. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURE Pain was assessed using a numeric rating scale for the following 5 conditions: rest pain, tenderness pain, stretch pain (SP), contraction pain, and weight-loading pain. Based on weight-loading pain, the subjects were divided into 2 groups: severe and moderate. Gliding of both the vastus lateralis (VL) muscle and subcutaneous (SC) tissue were recorded during knee motion using B-mode ultrasonography with a 12-MHz linear transducer fixed on the lateral thigh using an original fixation device. Particle image velocimetry analysis software was adapted to create the flow velocity of both VL muscle and SC tissue from echo imaging, and 2 regions of interest were selected on the VL muscle and SC tissue. Gliding was calculated using a coefficient of correlation from each time series data set. RESULTS Gliding and pain (stretch/contraction) were significantly different between the 2 groups at 3 weeks post operation. Changes in both weight-loading pain (r=0.49) and SP (r=0.42) correlated significantly with improvements in gliding. CONCLUSION Patients with weight-loading pain after surgery for TF showed decreased gliding during recovery, and an improvement in gliding was associated with improvements in both weight-loading pain and SP.

Incidence of four major types of osteoporotic fragility fractures among elderly individuals in Sado, Japan, in 2015. J Bone Miner Metab 2019; 37:484-490.

Abstract
The aim of this study was to survey the incidence of osteoporotic fragility fractures, which include vertebral, hip, distal radius, and proximal humerus fractures, in patients ≥ 50 years of age, from 2004 to 2015, in Sado City, Japan. We examined temporal changes in the incidence of these fractures from 2010 through 2015. The incidence of vertebral (p < 0.001) and radius fractures (p = 0.001) was lower in 2015 than in 2010, with only the incidence of hip fracture (p = 0.013) being lower in 2015 than in 2004. With regard to age-specific incidences, there was a sharp increase in vertebral and hip fractures among the segment of the population 70-89 years old, with no remarkable change in the incidence of radial and humeral fractures. Pre-existing vertebral fractures were identified in 69.6% of patients with a hip fracture, 35.6% of patients with a distal radius fracture, and 55% of patients with a humeral fracture. Among patients with pre-existing vertebral fractures, 42.5% had a single fracture, whereas 57.5% had 2 or more fractures. The proportion of patients on anti-osteoporotic agents before the occurrence of fractures increased to 14.5% in 2015, compared to 4% in 2004 and 7.6% in 2010. We speculate that the increase in the use of anti-osteoporotic agents is the main reason for the declining incidence of fractures. Therefore, considering the sharp increase in hip and vertebral fractures among individuals in their mid-1970s and older, judicious use of anti-osteoporotic agents among these individuals could be useful for lowering the occurrence of these fractures.

Abstract
INTRODUCTION Hip fractures are a societal burden because of their high morbidity and mortality and the cost they generate. With the aging of the population, worries grow about an increase of the incidence and incidence rate of hip fracture in the future. Controversial data have been provided in relation to the referencepopulation used. The aim of this study was to assess the impact of the choice of the reference population in the incidence rate of hip fracture. METHODS Data were extracted from the French National Hospital Database related to the hospitalizations for hip fracture in France between 2002 and 2013 in patients over 59 years and were classified by gender and age (59-74, 75-84, over 84 years, over 59 years). The crude incidence rates of hip fracture were calculated by dividing the number of hospitalizations for hip fracture by the corresponding populations. To assess the impact of the choice of the reference population, we then calculated the adjusted incidence rates using direct standardization on age for the 2013 reference population. RESULTS From 2002 to 2013, the incidence of hip fracture rose by 4.8% in women (from 49,287 to 51,661) and 21.8% in men (from 12,716 to 15,482) aged over 59 years. Meanwhile, French population over 59 years increased more with a rise of 21.3% in women and 28.7% in men, resulting in a decrease in the crude incidence rates of 13.6% in women and 5.4% in men. However, this decrease was larger after direct standardization on the 2013 population of reference as 25.6% in women and 19.2% in men as a result of a difference in age-structure of the population. CONCLUSIONS The incidence of hip fractures continues to grow despite a reduced incidence rate throughout a 12-year-period.

Abstract
UNLABELLED A model-based cost-effectiveness analysis was performed to evaluate the cost-effectiveness of implementing the clinical guideline for the treatment for glucocorticoid-induced osteoporosis (GIO). The treatment indication for GIO in the current Japanese clinical guidelines is likely to be cost-effective except for the limited patients who are at low risk for fracture. INTRODUCTION The purpose of this study was to evaluate the cost-effectiveness of implementing the clinical guideline for the treatment for glucocorticoid-induced osteoporosis (GIO) from the perspective of the Japanese healthcare system. METHODS A patient-level state transition model was developed to predict lifetime costs and quality-adjusted life years (QALYs) in postmenopausal Japanese women with osteopenia or osteoporosis using glucocorticoid (GC). An annual discount rate of 2% for both costs and QALYs was applied. The incremental cost-effectiveness ratio (ICER) of 5-year alendronate therapy compared with no therapy was estimated with different combinations of the risk factors such as starting age (45, 55, or 65), femoral neck BMD (% young adult mean (YAM) of 70%, 75%, or 80%), dose of GC (2.5, 5, or 10 mg per day), and the presence of previous fracture (yes or no). RESULTS For 55-year-old women using GC with a BMD of 75% of YAM, the ICER ranged from $10,958 to $ 29,727 per QALY. Scenario analyses indicated that the lower age, the lower BMD, the higher dose of GC, and the presence of previous fracture associated with lower ICER. The best-case scenario was 45-year-old women with a BMD of 70% of YAM, GC dose of 10 mg per day, and previous fracture, and resulted in healthcare cost-savings. The worst-case scenario was 65-year-old women with a BMD of 80% of YAM, GC dose of 2.5 mg per day, and no previous fracture, and resulted in the ICER of $66,791 per QALY. Sensitivity analyses in the worst-case scenario showed that the annual discount rate for costs and health benefit had the strong influence on the estimated ICER. Although the ICER was influenced by other parameters such as disutility due to vertebral fracture, efficacy of alendronate, and so on, the ICERs remained more than $50,000 per QALY. CONCLUSIONS The cost-effectiveness of preventive alendronate therapy for postmenopausal women with osteopenia or osteoporosis using GC is sensitive to age, BMD, GC dose, and the presence of previous fracture. Our analysis suggested that the treatment indication for postmenopausal women with osteopenia or osteoporosis using GC in the current Japanese clinical guidelines is likely to be cost-effective except for the limited patients who are at low risk for fracture.

Abstract
Background The present study aimed to assess the changes in trend of osteoporosis among the Taiwanese population from 2001 to 2011. Methods The National Health Insurance Research Database (NHIRD) of Taiwan, containing records from approximately 23 million insures from 2001 to 2011, was analyzed. Insurees aged≧50 years with osteoporosis were identified either from previously documented osteoporotic diagnosis or osteoporosis-related fractures according to Clinical Modification (ICD-9-CM) diagnostic code. Results The prevalence of osteoporosis increased from 17.4% in 2001 to 25.0% in 2011. The prevalence trend increased from 2001 to 2005 and plateaued thereafter. During 2001–2005, the incidence rate of hip fracture held steady from 277 to 281 per 100,000 person-years, and decreased thereafter from 262 to 247 per 100,000 person-years. The overall incidence of osteoporosis declined among patients younger than 84 years from 2001 to 2011, especially after 2005. As compared with 2005 and before, the incidence rate of osteoporosis was significantly decreased since 2006. Conclusions The secular changes of osteoporosis in Taiwan are quite similar to the trend in western countries. It reveals how osteoporosis awareness and policy interventions can affect the prevalence trend of osteoporosis.

Abstract
Osteoporosis has become a worldwide public health problem, in part due to the fact that it increases the risk of fragility hip fractures (FHFs). The epidemiological assessment of FHFs is critical for their prevention; however, datasets for FHFs in Japan remain scarce. This was a multicenter, prospective, observational study in the northern district of Kyushu Island. Inclusion criteria were age > 60 years with a diagnosis of FHF and acquisition of clinical data by an electronic data capture system. Of 1294 registered patients, 1146 enrolled in the study. Nearly one third of patients (31.8%) had a history of previous fragility fractures. The percentage of patients receiving osteoporosis treatment on admission was 21.5%. Almost all patients underwent surgical treatment (99.1%), though fewer than 30% had surgery within 48 h after hospitalization. Bone mineral density (BMD) was evaluated during hospitalization in only 50.4% of patients. The rate of osteoporosis treatment increased from 21.5% on admission to 39.3% during hospitalization. The main reasons that prescribers did not administer osteoporosis treatment during hospitalization were forgetfulness (28.4%) and clinical judgment (13.6%). Age and female ratio were significantly higher in patients with previous FHFs than in those without. There was a significant difference in the rate of osteoporosis treatment or L-spine BMD values in patients with or without previous FHFs on admission. In conclusion, this study confirmed that the evaluation and treatment of osteoporosis and FHFs is still suboptimal in Japan, even in urban districts.

A decrease in the number and incidence of osteoporotic hip fractures among elderly individuals in Niigata, Japan, from 2010 to 2015. J Bone Miner Metab 2018; 36:573-579. [PMID: 28884394 DOI: 10.1007/s00774-017-0863-2] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/10/2016] [Accepted: 08/03/2017] [Indexed: 10/18/2022]
Abstract
We investigated the incidence of hip fracture in patients aged ≥50 years in 2015 in Niigata Prefecture, Japan. We also determined the long-term trend in hip fracture incidence from 1985 to 2015. In 2015, 3214 hip fractures occurred in Niigata Prefecture. The crude incidence rate of hip fracture was 282.7 per 100,000 persons per year (122.9 in men and 416.4 in women). The incidence of hip fracture decreased from 2010 to 2015 in all age groups except in men aged 65-69 years and women aged 60-64 years. The percentage of patients who took anti-osteoporotic medication before their hip fractures increased from 10.2% in 2010 to 14.9% in 2015. The age-specific incidence in women tended to increase until 2010, but significantly decreased from 2010 to 2015 (p < 0.001). Similarly, the incidence in men decreased from 2010 to 2015 but was not significantly different from that in 1994 (p = 0.633); this incidence had been increasing since 1999. In conclusion, a generally increasing trend was observed in the incidence of hip fractures for 30 years in both men and women in Niigata Prefecture; however, it turned into a descending trend beginning in 2010.

Abstract
Intertrochanteric femur fractures are common injuries associated with significant patient morbidity and mortality and high societal costs. Although intramedullary devices have shown promises for treating a wide range of intertrochanteric femur fractures, improper technique can lead to malalignment, fracture displacement, and/or iatrogenic fractures. In particular, a "wedge effect" has been described, in which the passage of conical reamers and the intramedullary nail itself results in the distraction of intertrochanteric fragments with lateralization of the shaft from the femoral neck and varus malalignment. Here, we describe the mechanism by which this deformity is generated and describe techniques for preventing it, including the use of a modified starting point and an alternative to the conical opening reamers.

Ratio of Endogenous Secretory Receptor for Advanced Glycation End Products to Pentosidine Predicts Fractures in Men. J Clin Endocrinol Metab 2018; 103:85-94. [PMID: 29040721 DOI: 10.1210/jc.2017-00929] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/19/2017] [Accepted: 10/04/2017] [Indexed: 12/31/2022]
Abstract
CONTEXT Although the endogenous secretory receptor for advanced glycation end products (esRAGE) has been associated with reduced activity of pentosidine (PEN), the association between PEN, esRAGE, and fracture is poorly understood. OBJECTIVES To evaluate the ability of serum PEN and esRAGE levels to predict fragility fractures. METHODS A cohort of 1285 Japanese men aged ≥65 years old participated in a 2007 to 2008 Fujiwara-kyo Osteoporosis Risk in Men study baseline survey, as part of the Fujiwara-kyo prospective cohort study. Those participants provided information regarding any fractures they experienced during 5 years. The baseline bone mineral density (BMD) was measured. Hazard ratios (HRs) per one standard deviation increase of log-transformed serum levels of PEN, esRAGE, and esRAGE-to-PEN ratio were estimated at baseline. RESULTS Twenty-five participating men suffered incident clinical fragility fractures. The crude HRs (95% confidence interval) for PEN, esRAGE, and esRAGE-to-PEN ratio were 1.56 (1.05 to 2.31), 0.79 (0.54 to 1.15), and 0.65 (0.44 to 0.95), respectively. HRs for PEN adjusted for age, esRAGE, and T score of BMD at femoral neck (FN) and lumbar spine (LS) were 1.48 (1.00 to 2.18) and 1.51 (1.03 to 2.21), respectively. The marginal significance adjusted for BMD at FN and the statistical significance adjusted for BMD at LS were attenuated after additional adjustment for glycated hemoglobin A1c level (P = 0.111 and 0.072, respectively). The HRs for esRAGE-to-PEN ratio adjusted for age, glycated hemoglobin A1c, and T-score of BMD at FN and LS were 0.67 (0.45 to 0.98) and 0.64 (0.43 to 0.95). CONCLUSIONS Higher esRAGE-to-PEN ratios were associated with decreased risk of fragility fractures independent of BMD among elderly Japanese men.

Secular trends in major osteoporotic fractures among 50+ adults in Denmark between 1995 and 2010. Arch Osteoporos 2018; 13:91. [PMID: 30151659 PMCID: PMC6132403 DOI: 10.1007/s11657-018-0503-z] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/27/2018] [Accepted: 08/09/2018] [Indexed: 02/03/2023]
Abstract
UNLABELLED We investigated the incidence trend in all major osteoporotic fractures for the whole country of Denmark between 1995 and 2010. Hip and other osteoporotic fractures declined for the general population and especially among women. But, we observed some increasing trend among men which needs more attention. PURPOSE The trend in osteoporotic fractures is varied across the globe, and there is no updated information in the case of Denmark for all major osteoporotic fractures (MOF). Thus, we investigated the incidence rates (IRs) of MOF among 50+ adults in Denmark over the period 1995-2010. METHODS A series of cross-sectional analyses was done using the Danish National Health Service Register. Participants were 50+ adults in the full country Denmark with a MOF between 1995 and 2010. Gender- specific IRs of MOF per 10,000 person years (PYs) were estimated, in addition to IRs of individual fracture sites (hip, vertebrae, humerus, and radius/ulna), and women-to-men IR ratios for MOF. RESULTS A general decline was observed in IRs of MOF for the whole population (from 169.8 per 10,000 PYs in 1995, to 148.0 in 2010), which was more pronounced among women. Thirty-one and nineteen percent of decline was observed in hip fracture rates among women and men, respectively. The trend in clinical vertebral fracture was slightly decreasing for women and increasing for men. The women-to-men rate ratio of MOF decreased noticeably from 2.93 to 2.72 during study period. CONCLUSIONS We observed declining trends in MOF and hip fracture for both sexes. However, a lower rate of decrease of hip fracture and an increasing trend in vertebral fracture was noticed among men. Considering our observations and the major economic burden which accompanies this devastating disease, more attention should be paid to MOF, especially in men.

Trend in the Age-Adjusted Incidence of Hip Fractures in South Korea: Systematic Review. Clin Orthop Surg 2017; 9:420-423. [PMID: 29201294 PMCID: PMC5705300 DOI: 10.4055/cios.2017.9.4.420] [Citation(s) in RCA: 32] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/28/2017] [Accepted: 09/26/2017] [Indexed: 11/06/2022] Open
Abstract
Background The incidence of hip fractures has been reported to vary geographically, and its trend has also varied widely. However, the trend in the age-adjusted incidence of hip fractures has not been well studied in Korea. After we identified eligible studies presenting multiple age-adjusted incidences of hip fractures in the Korean population in PubMed, we evaluated changes in the absolute number of occurrence and calculated the annual percentage change (APC) of age-adjusted incidences of hip fractures. Methods We have searched PubMed for the original and English-language literature on the incidence of hip fractures in the Korean population published since 2000. The studies presenting multiple age-adjusted incidences of hip fractures were selected. We evaluated the change in the absolute number of hip fractures and calculated the APC of age-adjusted incidences of hip fractures for each study. Results Three eligible articles were identified. The absolute number of hip fractures for both genders increased over time in all three studies although the operational definition of hip fracture differed from one another. The APC of the age-adjusted incidence of hip fractures was positive for women and negative for men. However, the change was not statistically significant in both genders during each study period (2001–2004, 2005–2008, and 2006–2010, respectively). Conclusions The age-adjusted incidence of hip fractures was stable among men and women, while the absolute number of hip fractures increased for both genders in Korea. Further studies with longer study periods on age-adjusted incidences are required to better determine the trend in the incidence of hip fractures in Korea.

Abstract
Purpose To investigate whether assessment of bone strength with quantitative computed tomography (CT) in combination with dual-energy x-ray absorptiometry (DXA) is cost-effective as a screening tool for osteoporosis in postmenopausal women. Materials and Methods A state-transition microsimulation model of osteoporosis for postmenopausal women aged 55 years or older was developed with a lifetime horizon and U.S. societal perspective. All model inputs were derived from published literature. Three strategies were compared: no screening, DXA with T score-dependent rescreening intervals, and a combination of DXA and quantitative CT with different intervals (3, 5, and 10 years) at different screening initiation ages (55-65 years). Oral bisphosphonate therapy was started if DXA hip T scores were less than or equal to -2.5, 10-year risk for hip fracture was greater than 3% (World Health Organization Fracture Risk Assessment Tool score, or FRAX), 10-year risk for major osteoporotic fracture was greater than 20% (FRAX), quantitative CT femur bone strength was less than 3000 N, or occurrence of first fracture (eg, hip, vertebral body, wrist). Outcome measures were incremental cost-effectiveness ratios (ICERs) in 2015 U.S. dollars per quality-adjusted life year (QALY) gained and number of fragility fractures. Probabilistic sensitivity analysis was also performed. Results The most cost-effective strategy was combined DXA and quantitative CT screening starting at age 55 with quantitative CT screening every 5 years (ICER, $2000 per QALY). With this strategy, 12.8% of postmenopausal women sustained hip fractures in their remaining life (no screening, 18.7%; DXA screening, 15.8%). The corresponding percentages of vertebral fractures for DXA and quantitative CT with a 5-year interval, was 7.5%; no screening, 11.1%; DXA screening, 9%; for wrist fractures, 14%, 17.8%, and 16.4%, respectively; for other fractures, 22.6%, 30.8%, and 27.3%, respectively. In probabilistic sensitivity analysis, DXA and quantitative CT at age 55 years with quantitative CT screening every 5 years was the best strategy in more than 90% of all 1000 simulations (for thresholds of $50 000 per QALY and $100 000 per QALY). Conclusion Combined assessment of bone strength and bone mineral density is a cost-effective strategy for osteoporosis screening in postmenopausal women and has the potential to prevent a substantial number of fragility fractures. © RSNA, 2017 Online supplemental material is available for this article.

Decision Making in the Management of Extracapsular Fractures of the Proximal Femur - is the Dynamic Hip Screw the Prevailing Gold Standard? Open Orthop J 2017; 11:1213-1217. [PMID: 29290858 PMCID: PMC5721321 DOI: 10.2174/1874325001711011213] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/03/2017] [Revised: 05/18/2017] [Accepted: 06/22/2017] [Indexed: 11/22/2022] Open
Abstract
Currently, approximately half of all hip fractures are extracapsular, with an incidence as high as 50 in 100,000 in some countries. The common classification systems fail to explain the logistics of fracture classification and whether they all behave in the same manner. The Muller AO classification system is a useful platform to delineate stable and unstable fractures. The Dynamic hip screw (DHS) however, has remained the 'gold standard' implant of choice for application in all extracapsular fractures. The DHS relies on the integrity and strength of the lateral femoral wall as well as the postero-medial fragment. An analysis of several studies indicates significant improvements in design and techniques to ensure a better outcome with intramedullary nails. This article reviews the historical trends that helped to evolve the DHS implant as well as discussing if the surgeon should remain content with this implant. We suggest that the gold standard surgical management of extracapsular fractures can, and should, evolve.

Abstract
Bone mineral density (BMD) measurement by dual-energy X-ray absorptiometry (DXA) is the most commonly used method to assess fracture risk. DXA utilizes two different energy X-rays to calculate BMD and, by comparison to a young normative database, the T-score. In 1994, the World Health Organization defined osteoporosis based on T-score, changing the paradigm of the field and forever placing DXA measurements in the center of osteoporosis diagnosis. Since then, many large studies have demonstrated the predictive value of BMD by DXA-for every standard deviation decline in BMD, there is a relative risk of 1.5-2.5 for fracture. This predictive ability is similar to how blood pressure can predict myocardial infarction. Limitations of DXA are also important to consider. While BMD by DXA can identify those at risk, there is a significant overlap in the BMD of patients who will and will not fracture. Special considerations are also needed in men and ethnic minority groups. These groups may have different bone size, thus affecting the normative range of BMD, and/or distinct bone structure that affect the association between BMD and fractures. Finally, BMD can be affected by positioning errors or artifacts, including osteoarthritis, fracture, and jewelry. Of course, DXA has tremendous strengths as well-namely its wide availability, its low radiation exposure, and a large body of evidence that relate DXA measurements to fracture risk. For these reasons, DXA remains the cornerstone of fracture assessment now and for the foreseeable future.

Cost-effectiveness analysis of once-yearly injection of zoledronic acid for the treatment of osteoporosis in Japan. Osteoporos Int 2017; 28:1939-1950. [PMID: 28265718 PMCID: PMC5486933 DOI: 10.1007/s00198-017-3973-8] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/05/2016] [Accepted: 02/15/2017] [Indexed: 11/24/2022]
Abstract
UNLABELLED Model-based economic evaluation was performed to assess the cost-effectiveness of zoledronic acid. Although zoledronic acid was dominated by alendronate, the incremental quality-adjusted life year (QALY) was quite small in extent. Considering the advantage of once-yearly injection of zoledronic acid in persistence, zoledronic acid might be a cost-effective treatment option compared to once-weekly oral alendronate. INTRODUCTION The purpose of this study was to estimate the cost-effectiveness of once-yearly injection of zoledronic acid for the treatment of osteoporosis in Japan. METHODS A patient-level state-transition model was developed to predict the outcome of patients with osteoporosis who have experienced a previous vertebral fracture. The efficacy of zoledronic acid was derived from a published network meta-analysis. Lifetime cost and QALYs were estimated for patients who had received zoledronic acid, alendronate, or basic treatment alone. The incremental cost-effectiveness ratio (ICER) of zoledronic acid was estimated. RESULTS For patients 70 years of age, zoledronic acid was dominated by alendronate with incremental QALY of -0.004 to -0.000 and incremental cost of 430 USD to 493 USD. Deterministic sensitivity analysis indicated that the relative risk of hip fracture and drug cost strongly affected the cost-effectiveness of zoledronic acid compared to alendronate. Scenario analysis considering treatment persistence showed that the ICER of zoledronic acid compared to alendronate was estimated to be 47,435 USD, 27,018 USD, and 10,749 USD per QALY gained for patients with a T-score of -2.0, -2.5, or -3.0, respectively. CONCLUSION Although zoledronic acid is dominated by alendronate, the incremental QALY is quite small in extent. Considering the advantage of annual zoledronic acid treatment in compliance and persistence, zoledronic acid may be a cost-effective treatment option compared to alendronate.
