Increased 1-Year Revision Rates Among Left-Sided Intertrochanteric Femur Fractures.

OBJECTIVES: To compare 1-year revision rates among left-sided and right-sided intertrochanteric femur fractures. DESIGN: Retrospective. SETTING: 120+ contributing centers to multicentered database. PATIENT SELECTION CRITERIA: Patients who sustained intertrochanteric femur fracture (ITFF) and had a cephalomedullary nail (CMN) from 2015 to 2022 were identified. Patients were then stratified based on left-sided or right-sided fracture. Patients were excluded if younger than 18 years with <1-year follow-up. The intervention investigated was CMN on left or right side. OUTCOME MEASURES AND COMPARISONS: One-year revision surgery, comparing CMN performed on left or right side for ITFFs. RESULTS: In total, 113,626 patients met inclusion criteria, with 55,295 in the right-sided cohort and 58,331 in the left-sided cohort. There was no difference between cohorts with respect to age, gender, diabetes, osteoporosis, chronic kidney disease, or congestive heart failure (P > 0.05 for all). Patients who sustained a left ITFF and treated with a CMN were more likely to have revision surgery at 1 year (Left: 1.24%, Right: 0.90%; OR: 1.24; 95% confidence interval [CI], 1.15-1.1.33) or develop a nonunion or malunion (Left: 1.30%, Right: 0.98%; OR: 1.31; 95% CI, 1.14-1.52). The most common revision surgery conducted for both cohorts was conversion total hip arthroplasty (Left: 70.4% and Right: 70.0%). CONCLUSIONS: Patients who sustained a left intertrochanteric femur fracture and were treated with a CMN were more likely to undergo revision at 1 year due to nonunion. There were no differences in demographics and comorbidities between cohorts. Though left-sided versus right-sided confounding variables may exist, the difference in nonunion rate may be explained by clockwise torque of the lag screw used in most implants. Increased awareness, implant design, and improved technique during fracture reduction and fixation may help lower this disproportionate nonunion rate and its associated morbidity and financial impact. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

Trends in hip fracture rates in spain from 2001 to 2018.

The present study includes the longest period of analysis with the highest number of hip fracture episodes (756,308) described in the literature for Spain. We found that the age-adjusted rates progressively decreased from 2005 to 2018. We believe that this is significant because it may mean that measures such as prevention and treatment of osteoporosis, or programs promoting healthy lifestyles, have had a positive impact on hip fracture rates. PURPOSE: To describe the evolution of cases and rates of hip fracture (HF) in patients 65 years or older in Spain from 2001 to 2018 and examine trends in adjusted rates. METHODS: Retrospective, observational study including patients ≥65 years with acute HF. Data from 2001 to 2018 were obtained from the Spanish National Record of the Minimum Basic Data Set of the Ministry of Health. We analysed cases of HF, crude incidence and age-adjusted rates by sex, length of hospital stay (LOS) and in-hospital mortality, and used joinpoint regression analysis to explore temporal trends. RESULTS: We identified 756,308 HF cases. Mean age increased 2.5 years, LOS decreased 4.5 days and in-hospital mortality was 5.5-6.5%. Cases of HF increased by 49%. Crude rate per 100,000 was 533.3 (95% confidence interval [CI], 532.1-534.5), increasing 14.0% (95%CI, 13.7-14.2). Age-adjusted HF incidence rate increased by 6.9% from 2001 (535.7; 95%CI, 529.9-541.5) to 2005 (572.4; 95%CI, 566.7-578.2), then decreased by 13.3% until 2017 (496.1, 95%CI, 491.7-500.6). Joinpoint regression analysis indicated a progressive increase in age-adjusted incidence rates of 1.9% per year from 2001 to 2005 and a progressive decrease of -1.1% per year from 2005 to 2018. A similar pattern was identified in both sexes. CONCLUSIONS: Crude incidence rates of HF in Spain in persons ≥65 years from 2001 to 2018 have gradually increased. Age-adjusted rates show a significant increase from 2001 to 2005 and a progressive decrease from 2005 to 2018.

Evolving Effects of the COVID-19 Pandemic on Hip Fracture Outcomes: A Retrospective Comparison of Pre, Early, and Late Pandemic Timepoints.

INTRODUCTION: Hospital systems were strained during the COVID-19 pandemic, and although previous studies have shown that surgical outcomes in healthy hip fracture patients were unaffected in the initial months of the pandemic, subsequent data are limited. This study examined the evolution of hip fracture care throughout the COVID-19 pandemic. METHODS: A retrospective review (level III evidence) was done of surgically treated adult hip fractures at a Level 1 academic trauma center from January 2019 to September 2022, stratified into three groups: pre, early, and late pandemic. Continuous variables were evaluated with the Student t-test and one-way analysis of variance, categorical variables were evaluated with chi-squared, P < 0.05 considered significant. RESULTS: Late pandemic patients remained in the hospital 30.1 hours longer than early pandemic patients and 35.7 hours longer than prepandemic patients (P = 0.03). High-energy fractures decreased in the early pandemic, then increased in late pandemic (P < 0.01). Early pandemic patients experienced more myocardial infarctions (P < 0.01). No significant differences in time to surgery, revision surgery, 90-day mortality, or other adverse events were noted. CONCLUSION: To our knowledge, this is the longest study evaluating hip fracture outcomes throughout the COVID-19 pandemic. These results are indicative of an overburdened regional health system less capable of facilitating patient disposition.

Hospitalizations for hip and non-hip osteoporotic fractures in Belgium: nationwide trends between 2010 and 2021.

This study aimed to describe the incidence of hospitalizations for osteoporotic fractures in patients aged 50 years and over in Belgium between 2010 and 2021. A declining trend in crude and age-adjusted hospitalization incidence was observed, however, the absolute number of hospitalisations for osteoporotic fractures increased due to demographic changes. PURPOSE: The secular trends of hospitalizations for hip and other osteoporotic fractures between 2010 and 2021 in patients aged 50 years and over in Belgium are unknown. This study aimed to describe the incidence of hospitalizations for osteoporotic fractures in patients aged 50 years and over in Belgium between 2010 and 2021. METHODS: Population-based, retrospective study based on hospitalization data extracted by the national database NIHDI and demographical data retrieved from the Belgian Federal Bureau for Statistics. Data were combined to determine the crude and age-standardized hospitalization incidence of fractures of the hip, distal femur, pelvis, humerus, wrist, and spine (2010 as the reference year). RESULTS: A total of 445,234 hospitalizations for osteoporotic fractures were reported between 2010 and 2021 (excluding 2015). Hospitalizations increased by 5.8% between 2010 and 2021 (p = 0.013) with a higher increase in men (12.1%; p = 0.001) compared to women (4.1%; p = 0.041). The crude incidence of hospitalizations for all fractures per 100,000 persons per year decreased from 990 to 910 between 2010 and 2021 (p = 0.572). The age-standardized incidence for hospitalizations of any osteoporotic fracture in men declined from 5.30/1,000 to 4.42/1,000 (p = 0.010). In women, a similar decrease was observed (13.84/1,000 to 11.62/1,000; p = 0.003). Both age-standardized hospitalizations for hip and non-hip fractures showed a decrease in both sexes. CONCLUSION: Although a declining trend in the crude incidence per 100,000 and in the age-adjusted incidence of hospitalizations for osteoporotic fractures was observed, the absolute number of hospitalizations for osteoporotic fractures increased due to the demographic change of an ageing population.

Predictors of hip fracture in 15 European countries: a longitudinal study of 48,533 geriatric adults using SHARE dataset.

We investigated the risk factors for hip fracture in 48,533 European older adults for 8 years from 2013 onward. We identified female gender, age above 80, low handgrip strength, and depression as significant risk factors for hip fracture. Our findings may help identify high-risk populations for hip fractures in pre-clinical settings. OBJECTIVES: Hip fracture is a major cause of functional disability, mortality, and health costs. However, the identification and characterization of its causative factors remain poor. METHODS: We investigated demography, handgrip strength (HGS), depression, and multiple age-associated comorbidities for predicting future hip fracture in individuals aged 50 or above from 15 European countries (n = 48,533). All participants were evaluated from 2013 to 2020 using four successive waves of the Survey of Health, Aging, and Retirement in Europe (SHARE). RESULTS: Altogether, 1130 participants developed hip fractures during the study period. We identified female gender, an advancing age from quinquagenarians onward, and a poor socioeconomic status as critical risk factors for future hip fracture. Having mobility difficulty, a low HGS (< 27 kg in men, < 16 kg in women) and higher scores on Euro-D depression scales were also significant risk factors for hip fracture. Summated scales of hypertension, diabetes mellitus, cancer, Alzheimer's disease, and stroke did not appear as risk factors. CONCLUSION: Collectively, we report advancing age, female gender, low HGS, and depression as independent risk factors for hip fracture. Our findings are useful in identifying high-risk populations for hip fractures in pre-clinical settings before rigorous evaluation and treatment in clinics.

Comparative analysis of geriatric hip fracture management outcomes in teaching and nonteaching hospitals in Jordan.

Hip fractures are common orthopedic injuries that have significant impacts on patients and healthcare systems. Previous studies have shown varying outcomes for hip fracture management in different settings, with diverse postoperative outcomes and complications. While teaching hospital settings have been investigated, no studies have specifically examined hip fracture outcomes in teaching hospitals in Jordan or the broader Middle East region. Therefore, the aim of this study was to investigate this important outcome. A cohort comprising 1268 patients who underwent hip fracture fixation from 2017 to 2020 was analyzed for nine distinct outcomes. These outcomes encompassed time to surgery, ICU admissions, perioperative hemoglobin levels, length of hospital stay, readmission rates, revision procedures, and mortality rates at three time points: in-hospital, at 6-months, and at 1-year post-surgery. The analysis of 1268 patients (616 in teaching hospitals, 652 in non-teaching hospitals) showed shorter mean time to surgery in teaching hospitals (2.2 days vs. 3.6 days, p < 0.01), higher ICU admissions (17% vs. 2.6%, p < 0.01), and more postoperative blood transfusions (40.3% vs. 12.1%, p < 0.01). In-hospital mortality rates were similar between groups (2.4% vs. 2.1%, p = 0.72), as were rates at 6-months (3.1% vs. 3.5%, p = 0.65) and 1-year post-surgery (3.7% vs. 3.7%, p = 0.96). Geriatric hip fracture patients in teaching hospitals have shorter surgery times, more ICU admissions, and higher postoperative blood transfusion rates. However, there are no significant differences in readmission rates, hospital stays, or mortality rates at various intervals.

Association of serum levels of phenylalanine and tyrosine with hip fractures and frailty in older adults: The cardiovascular health study.

This study examined if the amino acids phenylalanine or tyrosine contribute to risk of hip fracture or frailty in older adults. We determined that neither phenylalanine nor tyrosine are important predictors of hip fracture or frailty. We suggest advice on protein intake for skeletal health consider specific amino acid composition. PURPOSE: Protein is essential for skeletal health, but the specific amino acid compositions of protein may have differential associations with fracture risk. The aim of this study was to determine the association of serum levels of the aromatic amino acids phenylalanine and tyrosine with risk for incident hip fractures over twelve years of follow-up and cross sectional associations with frailty. METHODS: We included 131 older men and women from the Cardiovascular Health Study (CHS) who sustained a hip fracture over twelve years of follow-up and 131 men and women without an incident hip fracture over this same period of time. 42% of this cohort were men and 95% were Caucasian. Weighted multivariable Cox hazards molecules were used to estimate the hazard ratios (HR) and 95% confidence intervals (CI) of incident hip fracture associated with a one standard deviation (SD) higher serum level of phenylalanine or tyrosine. Relative risk regression was used to determine the cross-sectional association of these amino acids with Freid's frailty index. RESULTS: Neither serum levels of phenylalanine (HR 0.85 (95% CI 0.62-1.16) or tyrosine (HR 0.82 (95% CI 0.62-1.1) were significantly associated with incident hip fractures or cross sectionally with frailty (frail compared with prefrail/not frail) (HR 0.92 (95% CI 0.48-1.76) and HR (0.86 (95% CI 0.46-1.61) respectively. CONCLUSION: Phenylalanine and tyrosine are not significant contributors to hip fractures or frailty in older men and women.

Analysis of the clinical characteristics and risk factors associated with contralateral hip fracture after initial hip fracture in elderly patients: a retrospective cohort study.

Fractures of the contralateral hip may easily occur in elderly patients after an initial hip fracture. The aim of this study was to investigate the clinical characteristics and major predisposing risk factors of contralateral hip fracture after initial hip fracture in the elderly, to provide a clinical basis for preventing contralateral hip fracture. The data of 1586 patients who had sustained first or second hip fractures and had been surgically treated in our department were retrospectively analyzed. Potential predictive factors for contralateral hip fracture and descriptive statistics associated with surgery (such as blood loss, operation time, and length of hospital stay) were recorded. Of these patients, 133 (8.4%) suffered contralateral hip fracture. The rates of contralateral fracture after femoral neck and intertrochanteric fracture were 5.4% and 10.7% respectively (P < 0.01). Fifty-four cases of contralateral hip fracture occurred within one year, an incidence of 40.6%, while 95 cases (71.4%) and 105 cases (78.9%) occurred within two and three years, respectively, with a interval duration of 21.6 months. The risk factors for contralateral hip fracture were found to be age, type of first fracture, bone mineral density, the Singh index, and concomitant internal medical diseases, which were found to be significantly associated with an increased risk of contralateral hip fracture in multivariate logistic regression analysis (P < 0.05). In conclusion, the presence of concomitant internal diseases, type of first fracture, bone mineral density, the Singh index, and age were found to be significant predictors of the risk of contralateral hip fracture in elderly patients after a first hip fracture.

Osteoporosis and Fracture Risk Associated with Novel Antidepressants: A Systematic Review and Meta-Analysis.

BACKGROUND: The use of antidepressants, especially selective serotonin reuptake inhibitors (SSRIs), has been linked to adverse effects on bone health, but findings are conflicting. This study aimed to quantify the associations between newer antidepressants and bone mineral density (BMD) and fracture risk through a comprehensive meta-analysis. METHODS: Observational studies on the association between the use of novel antidepressants and BMD and hip fracture were systematically searched in PubMed, Embase, CINAHL, Cochrane Library, and Scopus. Random effects meta-analyses were conducted to pool results across the eligible studies. The heterogeneity, publication bias, and influence were assessed extensively. RESULTS: 14 eligible studies with 1,417,134 participants were identified. Antidepressant use was associated with significantly lower BMD compared to non-use at all skeletal sites examined, with pooled standardized mean differences (SMD) ranging from -0.02 (total hip) to -0.04 (femoral neck). Importantly, antidepressant use was associated with a 2.5-fold increased risk of hip fracture (pooled odds ratio (OR) 2.50, 95% CI 2.26-2.76). While heterogeneity was detected, the overall findings were robust in sensitivity analyses. CONCLUSIONS: This meta-analysis provided strong evidence that novel antidepressants, especially widely used SSRIs, have detrimental impacts on bone health. The observed associations with decreased BMD and doubled hip fracture risk have important clinical implications.

Calculated Fracture Risk among Hypertensive and Non-hypertensive Osteoporotic Women.

Vertebral and Hip fractures are the commonly encountered in low bone mass condition termed as osteoporosis. Bone mass and structure also affected by hypertension leading to increased susceptibility to fractures. This comparative cross-sectional study was conducted at two tertiary care centers in Dhaka metropolis from 1st January 2017 to 31st December 2017 under the department of Community Medicine, National Institute of Preventive and Social Medicine (NIPSOM) to assess whether HTN is linked with higher OP fracture risk. In this study 54 hypertensive and 34 non-hypertensive osteoporotic female patients were involved. After face to face interview data were collected by using semi-structured questionnaire and checklist. Online assessment of fracture risk probability was done among the two groups by Fracture Risk Assessment Tool (FRAX) and statistical analysis was performed by Statistical Packages for Social Sciences (SPSS-23.0). In this study it is found that the mean ages were 61.94±9.362 years and 59.18±11.269 years for hypertensive and non-hypertensive patients respectively. Most of the patients with hypertensive (96.3%) and non-hypertensive (82.4%) were housewives. Mean duration of hypertension in osteoporotic women was 6.41±4.049 years while mean duration of osteoporosis was 8.80±5.022 years and 7.53±5.920 years in hypertensive and non-hypertensive patients respectively. The difference in risk of major osteoporotic fractures (MOF) by age was significantly (Χ², p<0.05) higher among patients aged 60-79 years and remarkably higher in hypertensive patients. In hypertensive patients though the risk of MOF by hypertension was relatively higher but it was not significant statistically (Χ², p>0.05). However the risk of hip fracture (HF) by hypertension was relatively higher among hypertensive patients and it was significant statistically (Χ², p<0.05). This reflects that the risk of hip fracture is higher significantly in hypertensive patients.

Does hip protector prevent falls and hip fractures? An umbrella review of meta-analyses.

BACKGROUND: Wearing hip protectors is a measure used to prevent hip fractures caused by falls. However, its protective effect has remained controversial in previous studies. This study provides a rationale for the use of hip protectors by pooling all the current meta-analysis evidence. METHODS: We conducted an umbrella review of all the current meta-analysis articles about the efficacy of hip protectors to reduce hip fractures and falls in communities and/or institutions. Major databases including EMBASE, Cochrane Library, PubMed and Web of Science, were searched up to June 2022. Two reviewers screened the studies, extracted the data, and conducted the methodological quality assessment independently. The primary outcome was the association statistic (odds ratio (OR), relative risk (RR), etc.) reported in the meta-analysis that quantified the influence of the intervention on hip fractures and falls compared to that of the control group. Narrative synthesis was also conducted. Forest plots and the AMSTAR score were used to describe the results and quality of the pooled literature, respectively. RESULTS: A total of six meta-analysis articles were included in the study. Hip protectors were effective at reducing hip fractures in older individuals who were in institutions (nursing or residential care settings) but not in communities (RR = 0.70, 95% CI 0.58 to 0.85, I2 = 42%, P < 0.001) (RR = 1.12, 95% CI 0.94 to 1.34, I2 = 0%, P = 0.20), and they did not reduce falls (RR = 1.01, 95% CI 0.90 to 1.13, I2 = 0%, P = 0.89). CONCLUSIONS: Hip protectors are effective at preventing hip fractures in institutionalized older adults but not in community-dwelling older adults. TRIAL REGISTRATION: This study has been registered in PROSPERO (PROSPERO ID: CRD42022351773).

Risk factors for subsequent fractures in hip fracture patients: a nested case-control study.

BACKGROUND: The risk factors for subsequent fractures following an initial hip fracture are not entirely understood. This study examined the clinical characteristics of hip fracture patients to identify potential risk factors associated with a higher risk of experiencing subsequent fractures. METHODS: We conducted a nested case-control study using data from the Chinese PLA General Hospital Hip Fracture Cohort between January 2008 and March 2022. The cases were individuals who experienced subsequent fractures following an initial hip fracture. Each case was matched with up to 2 controls who did not develop subsequent fractures. Important clinical factors were compared across groups, including traditional fracture risk factors and potential risk factors (e.g., comorbidities, falls risk, physical impairment, calcium or vitamin D use, and anti-osteoporosis medications). Conditional logistic regression analyses were used to evaluate the impact of these clinical features as potential risk factors for subsequent fractures. RESULTS: A total of 96 individuals who suffered from subsequent fractures were matched with 176 controls. The median time between the initial hip fracture and the subsequent fracture was 2.1 years. The overall proportion of patients receiving anti-osteoporosis treatment after initial hip fracture was 25.7%. In the multivariable regression analysis, living in a care facility (OR = 3.78, 95%CI: 1.53-9.34), longer hospital stays (OR = 1.05, 95%CI: 1.00-1.11), and falls after discharge (OR = 7.58, 95%CI: 3.37-17.04) were associated with higher odds of subsequent fractures. CONCLUSIONS: This study showed that living in a care facility, longer hospital stays, and falls after discharge may be independent risk factors for repeat fractures following an initial hip fracture. These findings could be used to identify and manage patients at high risk of subsequent fractures.

Management of periprosthetic hip fractures: current status and prospects; experience of the traumatology and orthopedics department of Mohammed VI University Hospital, Marrakech.

INTRODUCTION: The increase in hip arthroplasties predicts a rise in periprosthetic fractures in Morocco, posing challenges for orthopedic surgeons. Therapeutic strategies vary considerably, highlighting the absence of a universally accepted treatment protocol. AIM: To analyze the management of per-prosthetic hip fractures, while addressing the challenges associated with them. METHODS: This was a retrospective study, conducted in the trauma-orthopedics department between December 2015 and November 2022. Nineteen patients who presented to the hospital with fractures around a hip prosthesis were included. RESULT: Nineteen periprosthetic fractures were observed. The majority of patients (68%) were women, with an average age of 68. The Vancouver classification showed that 52.6% of the fractures were type B1, and 21.1% type C, while the other fracture types were distributed differently. These fractures were mainly associated with diagnoses such as femoral neck fracture (63.2%) and coxarthrosis (31.6%). We observed variations in treatment recommendations and results between the different series analyzed. We noted discrepancies with certain series concerning fracture types and therapeutic choices. However, in our series, we achieved satisfactory results, with successful consolidation and the absence of complications in all patients. CONCLUSION: These results underline the importance of an individualized approach to fracture management, taking into account the specificities of each case.

Hip Fracture Risk Assessment Tools for Adults Aged 80 Years and Older.

Importance: While adults aged 80 years and older account for 70% of hip fractures in the US, performance of fracture risk assessment tools in this population is uncertain. Objective: To compare performance of the Fracture Risk Assessment Tool (FRAX), Garvan Fracture Risk Calculator, and femoral neck bone mineral density (FNBMD) alone in 5-year hip fracture prediction. Design, Setting and Participants: Prognostic analysis of 3 prospective cohort studies including participants attending an index examination (1997 to 2016) at age 80 years or older. Data were analyzed from March 2023 to April 2024. Main Outcomes and Measures: Participants contacted every 4 or 6 months after index examination to ascertain incident hip fractures and vital status. Predicted 5-year hip fracture probabilities calculated using FRAX and Garvan models incorporating FNBMD and FNBMD alone. Model discrimination assessed by area under receiver operating characteristic curve (AUC). Model calibration assessed by comparing observed vs predicted hip fracture probabilities within predicted risk quintiles. Results: A total of 8890 participants were included, with a mean (SD) age at index examination of 82.6 (2.7) years; 4906 participants (55.2%) were women, 866 (9.7%) were Black, 7836 (88.1%) were White, and 188 (2.1%) were other races and ethnicities. During 5-year follow-up, 321 women (6.5%) and 123 men (3.1%) experienced a hip fracture; 818 women (16.7%) and 921 men (23.1%) died before hip fracture. Among women, AUC was 0.69 (95% CI, 0.67-0.72) for FRAX, 0.69 (95% CI, 0.66-0.72) for Garvan, and 0.72 (95% CI, 0.69-0.75) for FNBMD alone (FNBMD superior to FRAX, P = .01; and Garvan, P = .01). Among men, AUC was 0.71 (95% CI, 0.66-0.75) for FRAX, 0.76 (95% CI, 0.72-0.81) for Garvan, and 0.77 (95% CI, 0.72-0.81) for FNBMD alone (P < .001 Garvan and FNBMD alone superior to FRAX). Among both sexes, Garvan greatly overestimated hip fracture risk among individuals in upper quintiles of predicted risk, while FRAX modestly underestimated risk among those in intermediate quintiles of predicted risk. Conclusions and Relevance: In this prognostic study of adults aged 80 years and older, FRAX and Garvan tools incorporating FNBMD compared with FNBMD alone did not improve 5-year hip fracture discrimination. FRAX modestly underpredicted observed hip fracture probability in intermediate-risk individuals. Garvan markedly overpredicted observed hip fracture probability in high-risk individuals. Until better prediction tools are available, clinicians should prioritize consideration of hip BMD, life expectancy, and patient preferences in decision-making regarding drug treatment initiation for hip fracture prevention in late-life adults.

Hip fracture rate and osteoporosis treatment in Ontario: A population-based retrospective cohort study.

This population-based study analyzes hip fracture and osteoporosis treatment rates among older adults, stratified by place of residence prior to fracture. Hip fracture rates were higher among older adults living in the community and discharged to long-term care (LTC) after fracture, compared to LTC residents and older adults living in the community. Only 23% of LTC residents at high fracture risk received osteoporosis treatment. PURPOSE: This population-based study examines hip fracture rate and osteoporosis management among long-term care (LTC) residents > 65 years of age compared to community-dwelling older adults at the time of fracture and admitted to LTC after fracture, in Ontario, Canada. METHODS: Healthcare utilization and administrative databases were linked using unique, encoded identifiers from the ICES Data Repository to estimate hip fractures (identified using the Public Health Agency of Canada algorithm and International Classification of Diseases (ICD)-10 codes) and osteoporosis management (pharmacotherapy) among adults > 66 years from April 1, 2014 to March 31, 2018. Sex-specific and age-standardized rates were compared by pre-fracture residency and discharge location (i.e., LTC to LTC, community to LTC, or community to community). Fracture risk was determined using the Fracture Risk Scale (FRS). RESULTS: At baseline (2014/15), the overall age-standardized hip fracture rate among LTC residents was 223 per 10,000 person-years (173 per 10,000 females and 157 per 10,000 males), 509 per 10,000 person-years (468 per 10,000 females and 320 per 10,000 males) among the community to LTC cohort, and 31.5 per 10,000 person-years (43.1 per 10,000 females and 25.6 per 10,000 males). During the 5-year observation period, the overall annual average percent change (APC) for hip fracture increased significantly in LTC (AAPC = + 8.6 (95% CI 5.0 to 12.3; p = 0.004) compared to the community to LTC group (AAPC = + 2.5 (95% CI - 3.0 to 8.2; p = 0.248)) and the community-to-community cohort (AAPC - 3.8 (95% CI - 6.7 to - 0.7; p = 030)). However, hip fracture rate remained higher in the community to LTC group over the study period. There were 33,594 LTC residents identified as high risk of fracture (FRS score 4 +), of which 7777 were on treatment (23.3%). CONCLUSION: Overall, hip fracture rates have increased in LTC and among community-dwelling adults admitted to LTC after fracture. However, hip fracture rates among community-dwelling adults have decreased over time. A non-significant increase in osteoporosis treatment rates was observed among LTC residents at high risk of fracture (FRS4 +). Residents in LTC are at very high risk for fracture and require individualized based on goals of care and life expectancy.

Relationship between donepezil and fracture risk in patients with dementia with Lewy bodies.

AIM: Patients with dementia with Lewy bodies (DLB) are at a high risk for falls and fractures. Although cholinesterase inhibitors reportedly are effective in suppressing the progression of cognitive symptoms in DLB patients, their effects on fracture risk remain unclarified. This study aimed to evaluate the association between donepezil use and hip fracture risk in older patients with DLB. METHODS: Using the Japanese insurance claim database, we collected the data of patients aged ≥65 years with DLB from April 2012 to March 2019. After propensity score matching, we compared the fracture rate over 3 years between DLB patients receiving donepezil and those not receiving antidementia drugs. RESULTS: Altogether, 24 022 239 individuals aged ≥65 years were newly registered from April 2012 to March 2016 and had verifiable information from 6 months before to 3 years after the registration. We identified 6634 pure-DLB patients and analyzed the data of 1182 propensity score-matched pairs. The characteristics, including age, sex, fracture history, osteoporosis, and bone mineral density test rate, of the two groups were well balanced by propensity score matching. The incidence rate of hip fracture was significantly lower in DLB patients receiving donepezil than in those not receiving antidementia drugs (0.60 vs. 1.44/100 person-years, P < 0.001), whereas that of vertebral fractures was the same. CONCLUSIONS: Donepezil administration in Japanese people aged ≥65 years with DLB was significantly associated with a decreased risk of hip fracture. Donepezil may provide new benefits to DLB patients. Geriatr Gerontol Int 2024; 24: 782-788.

Associations of accelerometer-estimated free-living daily activity impact intensities with 10-year probability of osteoporotic fractures in adults.

PURPOSE: Accelerometers are used to objectively measure physical activity; however, the relationship between accelerometer-based activity parameters and bone health is not well understood. This study examines the association between accelerometer-estimated daily activity impact intensities and future risk estimates of major osteoporotic fractures in a large population-based cohort. METHODS: Participants were 3165 adults 46 years of age from the Northern Finland Birth Cohort 1966 who agreed to wear a hip-worn accelerometer during all waking hours for 14 consecutive days. Raw accelerometer data were converted to resultant acceleration. Impact magnitude peaks were extracted and divided into 32 intensity bands, and the osteogenic index (OI) was calculated to assess the osteogenic effectiveness of various activities. Additionally, the impact peaks were categorized into three separate impact intensity categories (low, medium, and high). The 10-year probabilities of hip and all major osteoporotic fractures were estimated with FRAX-tool using clinical and questionnaire data in combination with body mass index collected at the age of 46 years. The associations of daily activity impact intensities with 10-year fracture probabilities were examined using three statistical approaches: multiple linear regression, partial correlation, and partial least squares (PLS) regression. RESULTS: On average, participants' various levels of impact were 8331 (SD = 3478) low; 2032 (1248) medium; and 1295 (1468) high impacts per day. All three statistical approaches found a significant positive association between the daily number of low-intensity impacts and 10-year probability of hip and all major osteoporotic fractures. In contrast, increased number of moderate to very high daily activity impacts was associated with a lower probability of future osteoporotic fractures. A higher OI was also associated with a lower probability of future major osteoporotic fractures. CONCLUSION: Low-intensity impacts might not be sufficient for reducing fracture risk in middle-aged adults, while high-intensity impacts could be beneficial for preventing major osteoporotic fractures.

The burden of periprosthetic femoral fractures in England and Wales: Insights from the first two years of data collection in the National Hip Fracture Database and regional variation in care.

INTRODUCTION: Periprosthetic femoral fractures (PPFFs) represent an important healthcare problem, with a rising incidence noted due to an increase in the number of arthroplasty surgeries being performed. There is a current lack of national consensus as to how these complex, often frail patients are managed. AIMS: Our primary aim was to present the epidemiology of PPFFs in England and Wales over the first two years of data collection by the National Hip Fracture Database (NHFD). Secondary aims included how well the NHFD Key Performance Indicators (KPIs) are met for PPFF patients, whether centres reporting a higher burden of PPFF patients are more likely to meet KPIs compared to lower volume centres, and to also identify if regional variation in care for these patients exist. METHODS: Patients aged 60 years or over, admitted to any acute hospital in England or Wales with a PPFF within the period 1st January 2020 to 31st December 2021 were included. Fractures were classified using the Vancouver system. The primary outcome of interest was the incidence of PPFF in England and Wales. Secondary outcomes included i) geographical distribution, ii) pattern of injury, iii) treatment received, iv) KPI performance nationally, v) KPI performance by top 5 highest volume hospitals vs the rest, vi) KPI performance by region and vii) KPI performance compared with native hip fracture patients. RESULTS: A total of 5,566 PPFFs were reported during our study period. A 31 % increase in cases was seen between 2020 and 2021 (2,405 to 3,161). The South-West of England reported the highest burden of PPFFs (14 % of all cases reported in 2021). Vancouver B subtypes were most common around hip replacements (62 %) and C subtype around knee replacements (55 %). A total of 4,598 patients (82.6 %) underwent operative management. There was regional variation in KPI attainment. When compared to KPI attainment for native hip fractures PPFF care under performed in most regions and domains. High volume PPFF centres were not associated with improved attainment of KPIs. CONCLUSION: We have described the incidence, nature, and management of PPFF at national and regional levels using routinely collected NHFD data. Both numerically and due to case complexity, PPFF are a considerable challenge to patients and health services alike. This epidemiology is not captured by other existing datasets and increased case contribution to the NHFD is encouraged to improve understanding and enable prioritisation and delivery of further care and research.

Association of depressive symptoms with incident fractures: the Japan Public Health Center-based Prospective Study for the Next Generation (JPHC-NEXT).

This 5-year longitudinal study investigated the relationship between depressive symptoms and fracture risk in a large Japanese cohort. Depressive symptoms were a significant risk factor for hip fractures in women. PURPOSE: A relationship between depressive symptoms and fractures has not been clearly demonstrated. We aimed to investigate the relationship between depressive symptoms and 5-year fracture risk in the Japan Public Health Center-based Prospective Study for the Next Generation. METHODS: From 2011 to 2016, 114,092 participants were enrolled, and a follow-up survey was conducted 5 years later. We analyzed 30,552 men and 38,063 women aged 40-74 years who had no past fractures at baseline. Presence of depressive symptoms was defined as a modified 11-item Center for Epidemiological Studies Depression Scale score of 8 or higher, a history of depression, or use of antidepressants. Subjects were asked to report vertebral, upper limb, and/or hip fractures, except for traffic or work accidents, that occurred during the follow-up period. The adjusted odds ratios (AORs) and 95% confidence intervals (CIs) for fracture were analyzed via logistic regression analysis to evaluate the relationship between depressive symptoms and fracture. RESULTS: Women with depressive symptoms demonstrated a high AOR for hip fractures (AOR: 2.78, 95% CI: 1.30 - 5.92); this result was consistent in post menopause women. In men, this association was not found for any age group or any type of fracture. CONCLUSIONS: Depressive symptoms in women may increase the risk of hip fractures. Further studies are required to explore this relationship in more detail.

Osteoporosis management in adults with schizophrenia following index hip fracture event: a 10-year population-based retrospective cohort study, Ontario, Canada.

Little is known about the incidence of osteoporosis testing and treatment in individuals with schizophrenia, who may be more likely to fracture. Using competing risk models, we found that schizophrenia was associated with lower incidence of testing or treatment. Implications are for understanding barriers and solutions for this disadvantaged group. PURPOSE: Evidence suggests that individuals with schizophrenia may be more likely to experience hip fractures than the general population; however, little is known about osteoporosis management in this disadvantaged subpopulation. Our study objective was to compare bone mineral density (BMD) testing and pharmacologic treatment in hip fracture patients with versus without schizophrenia. METHODS: This was a retrospective population-based cohort study leveraging health administrative databases, and individuals aged 66-105 years with hip fracture between fiscal years 2009 and 2018 in Ontario, Canada. Schizophrenia was ascertained using a validated algorithm. The outcome was a composite measure of (1) pharmacologic prescription for osteoporosis; or (2) a BMD test. Inferential analyses were conducted using Fine-Gray subdistribution hazard regression, with mortality as the competing event. RESULTS: A total of 52,722 individuals aged 66 to 105 years who sustained an index hip fracture in Ontario during the study period were identified, of whom 1890 (3.6%) had schizophrenia. Hip fracture patients with vs without schizophrenia were more likely to be long-term care residents (44.3% vs. 18.1%; standardized difference, 0.59), frail (62.5% vs. 36.5%; standardized difference, 0.54) and without a primary care provider (9.2% vs. 4.8%; standardized difference, 0.18). In Fine-Gray models, schizophrenia was associated with a lower incidence of testing or treatment (0.795 (0.721, 0.877)). CONCLUSIONS: In this population-based retrospective cohort study, a schizophrenia diagnosis among hip fracture patients was associated with a lower incidence of testing or treatment, after accounting for mortality, and several enabling and predisposing factors. Further research is required to investigate barriers to osteoporosis management in this disadvantaged population.
