Clark P, Cruz-Priego GA, Rascón-Pacheco RA, Bremer A, Borja-Aburto VH. Incidence of hip fractures in Mexico 2006-2019: increasing numbers but decreasing rates. Osteoporos Int 2024; 35:1041-1048. [PMID: 38459139 DOI: 10.1007/s00198-024-07045-0] [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: 10/23/2023] [Accepted: 02/27/2024] [Indexed: 03/10/2024]
Abstract
This study, characterizing the incidence of hip fractures in Mexico, showed not only that the crude number of fractures has increased, but also there has been a decrease in fracture rates. Nonetheless, as the population ages in the coming decades, the current declines rate of could be expected to reverse. PURPOSE This study is to examine the incidence, rates, and time trends of hip fractures from 2006 to 2019 in Mexico. Additionally, an analysis of the follow-up of the birth cohorts was carried out. METHODS Hip fractures registered during the period of the study were obtained through the Mexican Social Security Institute (IMSS) national discharge records. The incidence per 100,000 individuals was calculated from the IMSS population at risk. A time trend analysis was conducted using linear regression, and the identification of breakpoints in linear trends. RESULTS There was an increase of hip fractures for both sexes ≥ 60 years (43% for women and 41%, for men). However, the rates diminished from 167.8/100,000 in 2006 to 138.5 /100,000 in the population 60 and over (1.9% and 0.9% per year in women and men respectively). When the information was analyzed by age groups, hip fracture rates were similar in both sexes but higher in women. The most significant contribution to the total number of fractures is due to the groups ≥ 70 years; people born before 1937 are accounting for the burden of fractures over the total data. In contrast, the younger generations appear to have lower rates. CONCLUSION Rates of hip fracture have steadily declined in Mexico since 2006; however, with the population aging in the coming decades, current rates declines could be expected to reverse.

[PMID: 37119329 PMCID: PMC10382328 DOI: 10.1007/s00198-023-06774-y] [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: 03/17/2023] [Accepted: 04/21/2023] [Indexed: 05/01/2023]
Abstract
This study evaluated the incidence rates and societal burden of hip fractures in The Netherlands. Although incidence in the elderly population is decreasing and hospital stay is at an all-time low, the burden of medical costs and crude numbers of proximal femoral fractures are still rising in our aging population. PURPOSE The aim of this nationwide study was to provide an overview of the incidence rate and economic burden of acute femoral neck and trochanteric fractures in The Netherlands. METHODS Data of patients who sustained acute proximal femoral fractures in the period January 1, 2000, to December 31, 2019, were extracted from the National Medical Registration of the Dutch Hospital Database. The incidence rate, hospital length of stay (HLOS), health care and lost productivity costs, and years lived with disability (YLD) were calculated for age- and sex-specific groups. RESULTS A total of 357,073 patients were included. The overall incidence rate increased by 22% over the 20-year study period from 16.4 to 27.1/100,000 person-years (py). The age-specific incidence rate in elderly > 65 years decreased by 16% (from 649.1 to 547.6/100,000 py). The incidence rate in men aged > 90 has surpassed the incidence rate in women. HLOS decreased in all age groups, hip fracture subtypes, and sexes from a mean of 18.5 to 7.2 days. The mean health care costs, over the 2015-2019 period, were lower for men (€17,723) than for women (€23,351) and increased with age to €26,639 in women aged > 80. Annual cumulative costs reached €425M, of which 73% was spent on women. CONCLUSION The total incidence of hip fractures in The Netherlands has increased by 22%. Although incidence in the elderly population is decreasing and HLOS is at an all-time low, the burden of medical costs and crude numbers of proximal femoral fractures are still rising in our aging population.

[PMID: 34969583 DOI: 10.1016/j.jos.2021.12.004] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/28/2020] [Revised: 12/05/2021] [Accepted: 12/08/2021] [Indexed: 11/27/2022]
Abstract
BACKGROUND This study aimed to determine characteristics of acetabular fractures in the elderly by evaluating clinical course and computed tomography-based radiological features between low- and high-energy acetabular fractures. METHODS We reviewed 178 consecutive patients with acetabular fractures aged ≥60 years from six centers. Low-energy fractures (group 1) were identified in 23 (12.9%) patients and high-energy fractures (group 2) in 155 (87.1%) patients. We compared demographics, radiological findings, and clinical course between the groups. RESULTS Average age (70.6 vs. 67.8 years, p = 0.046) and ratio of females (47.8% vs. 23.2%, p = 0.021) were significantly higher in group 1 than in group 2. The Charlson comorbidity index was also higher in group 1, but no other demographics showed difference. More patients in group 2 than in group 1 underwent surgery (91.6% vs. 73.9%); however, more in group 1 underwent minimally invasive surgery (17.4% vs 4.5%). Anterior column-associated fracture patterns occurred in 91.4% and 38.7% of cases in groups 1 and 2, respectively. Most fractures were displaced (>2 mm); 68% of which were comminuted. Furthermore, 24.2% of the fractures had superior dome impaction, whereas 23.0% were associated with posterior wall impaction. CONCLUSIONS Patients who sustained low-energy acetabular fractures were mostly women, were older, and had more comorbidities. Radiological findings of low-energy acetabular fractures showed anterior column involvement associated with injury to the quadrilateral surface. Additionally, it was observed to be commonly combined with comminution and impacted fragments.

Changing trends in hip fracture epidemiology in the Republic of Ireland: a follow-up study. Arch Osteoporos 2022; 17:79. [PMID: 35575820 DOI: 10.1007/s11657-022-01112-x] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/04/2021] [Accepted: 04/25/2022] [Indexed: 02/03/2023]
Abstract
A national, population-based study of hip fracture epidemiology is reported following a previously published study for the same population to ascertain the accuracy of projected incidence rates. Results suggest a decline in age-specific incidence rates in females but not males, and an over-estimation of same in the previously reported projections. PURPOSE Accurate estimates of hip fracture numbers and incidence rates are necessary for health service resource planning. A study in 2009 estimated projected figures for 2016 and 2026, for the Republic of Ireland. The purpose of the current study was to scrutinize these projections, based upon actual population and fracture statistics for the year 2016. METHODS Population data was obtained from the Central Statistics Office, and hip fracture data was obtained from the National HIPE Database for the year 2016, using similar search criteria to the previously published study. Hip fracture numbers and incidence rates were calculated. The calculated figures were compared to projected figures from the previous report. RESULTS Population projection models used in the 2009 paper accurately reflected the 2016 Irish population. For younger age groups, projected number of fractures closely estimated actual numbers, however, for those over 70 years of age, hip fracture projections overestimated the actual fracture numbers observed. There was a significant difference in the age-specific hip fracture rates in the over 70 s sub-groups compared to the published results of the 2009 study. CONCLUSIONS Hip fracture numbers continue to increase, though the age-specific incidence rates in the Republic of Ireland are reducing in the older age groups. The previously published study over-estimated hip fracture projections for the year 2016 (and potentially 2026) due to a false assumption of a stable age-specific incidence rate in the Republic of Ireland, which is in fact reducing.

Decreasing hip fracture rates among older adults in Chile, 2001-2019. Arch Osteoporos 2022; 17:26. [PMID: 35091883 DOI: 10.1007/s11657-022-01067-z] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/20/2021] [Accepted: 01/20/2022] [Indexed: 02/03/2023]
Abstract
Our aim was to analyze trends in hip fracture rates in people aged ≥ 65 years, from 2001 to 2019 in Chile. Age-standardized incidence rates decreased significantly in both genders over the study period. PURPOSE To describe and analyze the characteristics and trends of osteoporotic hip fractures in Chile from 2001 to 2019, by age and sex. METHODS We assessed hip fractures in people aged ≥ 65 years using data from the hospital discharge register of Chile's Department of Statistics and Health. The Joinpoint regression analysis software was used to perform a trend analysis. RESULTS From 2001 to 2019, a total of 107.972 patients aged ≥ 65 years were hospitalized in Chile with a diagnosis of hip fracture (S72.0, S72.1, and S72.2). 77.4% of the patients were females, and 63.7% were adults aged ≥ 80 years. The average annual incidence rate over this period was 358.3/100.000 in the whole population (95% CI: ± 12.8), 195.2/100.000 in men (95% CI: ± 9), and 482/100.000 in women (95% CI: ± 15.5). After an adjustment for age, hip fracture rates decreased annually on average by 1.0% (p < 0.001, 95% CI: - 1.4%, - 0.7%), from 358.5/100.000 in 2001 to 331.7/100.000 in 2019. Hip fracture rates decreased annually in both men (- 1.4%, p < 0.001) and women (- 0.9%, p < 0.001). CONCLUSION The incidence of osteoporotic hip fractures has been decreasing annually and significantly in Chile since 2001, both in men and women. This may be caused by increased levels of obesity and a lower risk of falling among older adults. We recommend further studies to assess all factors contributing to this change in hip fracture rates.

Abstract
INTRODUCTION Fractures of the pelvis and acetabulum are associated with osteoporosis, and their incidence is rising in older adults. In the last decade an increasing number of these fractures are being operated in older patients in certain regions. The goal of this study was to describe the incidence of pelvic and acetabular fractures in Belgium between 1988 and 2018. MATERIALS & METHODS This retrospective, nationwide, population-based study was conducted with the help of the national health insurance database from the Belgian National Institute for Health and Disability Insurance (NIHDI-RIZIV-INAMI). Multiple codes for the reimbursement of the diagnosis and treatment of pelvic and acetabular fractures were collated and (since 2006) linked to the patients' age group, sex and region. RESULTS Between 1988 and 2018, 91.317 pelvic and acetabular fractures were diagnosed. The overall incidence increased from 15,8/100.000 persons per year in 1988 to 29,7/100.000 persons per year in 2006 and to 37,6/100.000 persons per year in 2018. These fractures showed a bimodal incidence, with a small peak in children (particularly boys), and an increasing incidence in older adults, particularly in women. Between 2006 and 2018, 5.957 (12,4%) patients underwent surgical treatment for their pelvic fracture. 2.088 patients underwent an osteosynthesis of the acetabulum and 3869 patients underwent an osteosynthesis of the pelvic ring. There were 3622 osteosynthesises (60.8%) in patients younger than 60 years old and 2335 (39,1%) in patients over 60 years old. CONCLUSION There is an increasing incidence of pelvic and acetabular fractures in Belgium with the majority of these fractures occurring in older people. Younger adults have the highest proportion of surgical treatment, but given the much higher incidence in older adults, there is a considerable amount of operations in older adults too.

Abstract
Background and purpose - Extensive research and national multidisciplinary programs have striven to introduce uniform standards of treatment and mitigate mortality and adverse events after hip fracture surgery over the past decades. A large-scale overview of temporal developments in hip fracture surgery and care is warranted.Patients and methods - We studied Danish patients aged ≥ 60 years, sustaining their first ever hip fracture between 1997 and 2017. Patients were identified from the Danish National Patient Registry (DNPR). Incidence rates of first hip fracture were calculated per 1,000 patient-years and stratified by age group and sex. Information on pre-injury living settings, comorbidities, and medications were obtained from national administrative registers. Type of fracture and treatment choice were recorded, and patients were followed for 1 year to observe mortality, readmission, and surgical complications.Results - Data from 153,058 patients was analyzed. Incidence rate decreased in both sexes, but only led to a reduction in the annual number of hip fractures in the female population. Choice of surgery shifted away from sliding hip screws and parallel implants (SHS-PI), towards intramedullary nailing and hemi-/arthroplasties for trochanteric and femoral neck fractures, respectively. Pre-injury diagnosed morbidity and 1-year readmissions increased contrary to mortality. Median age remained stable around 83 (IQR 77-88) for women and 80 (IQR 73-86) for men.Interpretation - Over the past 2 decades important aspects of hip fracture management have improved. However, sex differences were observed, and men remain more vulnerable than women in terms of morbidity, mortality, and incidence rate.

Abstract
UNLABELLED In Kyoto Prefecture, Japan, the number of hip fractures increased during 2013-2017 compared to 2008-2012. However, the estimated overall incidence rate increased only in femoral neck fractures in men aged ≥75 and women aged ≥85. PURPOSE The incidence rate of hip fractures in Japan has plateaued or decreased. We investigated the annual hip fracture occurrences in Kyoto Prefecture, Japan, from 2008 to 2017. METHODS Patients aged 65 years and above who sustained hip fractures between 2008 and 2017 and were treated at one of the participating 11 hospitals were included. The total number of beds in these institutions was 3701, accounting for 21.5% of the 17,242 acute-care beds in Kyoto Prefecture. The change in incidence rate was estimated utilizing the population according to the national census conducted in 2010 and 2015. RESULTS The total number of hip fractures was 10,060, with 47.5% femoral neck fractures and 52.5% trochanteric fractures. A decrease in number was seen only in trochanteric fractures in the group of 75- to 84-year-old women. The population-adjusted numbers of femoral neck fractures showed a significant increase in all age groups in men, whereas in women, there was an increase in femoral neck fractures in the ≥85 group and trochanteric fractures in the age group 65-74, and a decrease in trochanteric fractures in the age group 75-84. The estimated change in incidence rate showed an increase in femoral neck fractures in men aged ≥75 and women aged ≥85. CONCLUSION In Kyoto Prefecture, the number of hip fractures increased in the second half of the study period (2013-2017) compared to the first half (2008-2012). However, the incidence rate had not increased, except in femoral neck fractures in men aged ≥75 and women aged ≥85.

[PMID: 33188958 DOI: 10.1016/j.bone.2020.115752] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/29/2020] [Revised: 10/20/2020] [Accepted: 11/09/2020] [Indexed: 02/08/2023]
Abstract
Osteoporosis-related fractures are a growing public health concern worldwide due to high societal and economic burden. The study aims to assess trends in incidence rates of hip and distal femoral fractures and in the use of anti-osteoporosis drugs in Italy between 2007 and 2017. Patients with hip and distal femoral fractures (ICD-9-CM codes 820.x and 821.x) were identified in the Italian National Hospital Discharge Database while anti-osteoporosis medication data were retrieved from the National Observatory on the Use of Medicines Database. A joinpoint regression analysis was performed to identify the years where the trends in incidence rates of hip and distal femoral fractures changed significantly; the average annual percentage change for the period of observation was estimated. Hospitalizations for femoral fractures were 991,059, of which 91.4% were hip fractures and 76.5% occurred in women. Age-standardized hip fractures rate per 100,000 person-years decreased both in women (-8.7%; from 789.9 in 2007 to 721.5 in 2017) and in men (-4.3%; from 423.9 to 405.6), while the rate of distal femoral fractures increased by 23.9% in women (from 67.78 to 83.95) and 22.7% in men (from 27.76 to 34.06). These changes were associated with an increment in the use of anti-osteoporosis drugs from 2007 to 2011 (from 9.1 to 12.4 DDD/1000 inhabitants/day), followed by a plateau in the period 2012-2017. The use of bisphosphonates increased progressively from 2007 to 2010 (from 8.2 to 10.5 DDD/1000 inhabitants/day), followed by a plateau and then decreased from 2015 onwards. The decreasing trend of hip fractures could be related to a major intake of anti-osteoporosis medications while the increment of distal femoral fractures might be due to population aging and to the use of bisphosphonates and denosumab. Further research is needed to identify and implement interventions to prevent hip and distal femoral fractures.

The effect of body configuration on the strain magnitude and distribution within the acetabulum during sideways falls: A finite element approach. J Biomech 2020; 114:110156.

Abstract
While the incidence of hip fractures has declined during the last decades, the incidence of acetabular fractures resulting from low-energy sideways falls has increased, and the mechanisms responsible for this trend remain unknown. Previous studies have suggested that body configuration during the impact plays an important role in a hip fracture. Thus, the aim of this study was to investigate the effect of body configuration angles (trunk tilt angle, trunk flexion angle, femur horizontal rotation angle, and femur diaphysis angle) on low-energy acetabular fractures via a parametric analysis. A computed tomography-based (CT) finite element model of the ground-proximal femur-pelvis complex was created, and strain magnitude, time-history response, and distribution within the acetabulum were evaluated. Results showed that while the trunk tilt angle and femur diaphysis angle have the greatest effect on strain magnitude, the direction of the fall (lateral vs. posterolateral) contributes to strain distribution within the acetabulum. The results also suggest that strain level and distribution within the proximal femur and acetabulum resulting from a sideways fall are not similar and, in some cases, even opposite. Taken together, our simulations suggest that a more horizontal trunk and femoral shaft at the impact phase can increase the risk of low-energy acetabular fractures.

Abstract
Background and purpose - Information on the epidemiological trends of pelvic fractures and fracture surgery in the general population is limited. We therefore determined the incidence of pelvic fractures in the Finnish adult population between 1997 and 2014 and assessed the incidence and trends of fracture surgery.Patients and methods - We used data from the Finnish National Discharge Register (NHDR) to calculate the incidence of pelvic fractures and fracture surgery. All patients 18 years of age or older were included in the study. The NHDR covers the whole Finnish population and gives information on health care services and the surgical procedures performed.Results and interpretation - We found that in Finnish adults the overall incidence of hospitalization for a pelvic fracture increased from 34 to 56/100,000 person-years between 1997 and 2014. This increase was most apparent for the low-energy fragility fractures of the elderly female population. The ageing of the population is likely therefore to partly explain this increase. The annual number and incidence of pelvic fracture surgery also rose between 1997 and 2014, from 118 (number) and 3.0 (incidence) in 1997 to 187 and 4.3 in 2014, respectively. The increasing number and incidence of pelvic fractures in the elderly population will increase the need for social and healthcare services. The main focus should be on fracture prevention.

Abstract
BACKGROUND Hip fracture is a public health concern because of its considerable morbidity, excess mortality, great risk of disability, and high societal healthcare costs. China has the largest population of older people in the world and is experiencing rapid population aging and facing great challenges from an increasing number of hip fractures. However, few studies reported the epidemiology, especially at a national level. We aimed to evaluate trends in hip fracture incidence and associated costs for hospitalization in China. METHODS AND FINDINGS We conducted a population-based study using data between 2012 and 2016 from the national databases of Urban Employee Basic Medical Insurance and Urban Resident Basic Medical Insurance in China, covering about 480 million residents. Data from around 102.56 million participants aged 55 years and older during the study period were analyzed. A total of 190,560 incident hip fracture patients (mean age 77.05 years, standard deviation 8.94; 63.99% female) were identified. Primary outcomes included the age- and sex-specific incidences of hip fracture. Associated annual costs for hospitalization were also calculated. Incidence was described as per 100,000 person-years at risk, and 95% confidence intervals were computed assuming a Poisson distribution. Hip fracture incidence overall in China did not increase during the study period despite rapid population aging. Incidence per 100,000 was 180.72 (95% CI 137.16, 224.28; P < 0.001) in 2012 and 177.13 (95% CI 139.93, 214.33; P < 0.001) in 2016 for females, and 121.86 (95% CI 97.30, 146.42; P < 0.001) in 2012 and 99.15 (95% CI 81.31, 116.99; P < 0.001) in 2016 for males. For both sexes, declines in hip fracture incidence were observed in patients aged 65 years and older, although incidence was relatively stable in younger patients. However, the total absolute number of hip fractures in those 55 years and older increased about 4-fold. The total costs for hospitalization showed a steep rise from US$60 million to US$380 million over the study period. Costs for hospitalization per patient increased about 1.59-fold, from US$4,300 in 2012 to US$6,840 in 2016. The main limitation of the study was the unavailability of data on imaging information to adjudicate cases of hip fracture. CONCLUSIONS Our results show that hip fracture incidence among patients aged 55 and over in China reached a plateau between 2012 and 2016. However, the absolute number of hip fractures and associated medical costs for hospitalization increased rapidly because of population aging.

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.

Tibial shaft fractures in Finland between 1997 and 2014. Injury 2019; 50:973-977. [PMID: 30935744 DOI: 10.1016/j.injury.2019.03.034] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/12/2018] [Revised: 03/17/2019] [Accepted: 03/20/2019] [Indexed: 02/02/2023]
Abstract
INTRODUCTION Tibial shaft fracture is common, accounting for 2% of all adult fractures. Large epidemiological follow ups are lacking and previous studies have shown great variation in incidence rates and trends. The aim of this population-based nationwide study was to analyze all tibial shaft fractures in Finland in 1997-2014 and to provide an update on current epidemiological data. PATIENTS AND METHODS Patient data was collected from the Finnish National Hospital Discharge Register (NHDR) from 1997 to 2014. The study covered the entire adult (18 years and older) population. The primary outcome was the annual number of hospitalization due to a fresh tibial shaft fracture. RESULTS A total of 14,150 patients with a fresh tibial shaft fracture were identified during the 18-year study period. The total fracture incidence decreased from 27.3 per 100,000 person-years in 1997 to 13.5 per 100,000 person-years in 2014. In men, the incidence was 34.9 in 1997 vs. 15.6 in 2014, while in women the corresponding numbers were 20.2 in 1997 vs. 11.5 in 2014. CONCLUSIONS The incidence of tibial shaft fractures has markedly decreased in Finland between 1997 and 2014, mainly because of a declining trend in the incidence of fall-induced low-energy fractures. Reasons for this development are uncertain and therefore more comprehensive population-based epidemiological studies are needed to reveal the factual reasons behind the decrease.

Abstract
UNLABELLED This study compared hip fracture rates and health outcomes of older people living in residential aged care facilities (RACFs) to the community. The RACF resident age-standardised hospitalisation rate was five times higher than the community rate and declining. RACF residents experience overall worse health outcomes and survival post-hip fracture. INTRODUCTION To compare hospitalisation trends, characteristics and health outcomes following a fall-related hip fracture of older people living in residential aged care facilities (RACFs) to older people living in the community. METHODS A retrospective analysis of fall-related hip fracture hospitalisations of people aged ≥ 65 years during 1 July 2008 and 30 June 2013 in New South Wales (NSW), Australia's largest populated state. Linked hospitalisation, RACF and Aged Care Assessment Appraisal data collections were examined. Negative binomial regression examined the significance of hospitalisation temporal trends. RESULTS There were 28,897 hip fracture hospitalisations. One-third were of older people living in RACFs. The hospitalisation rate was 2180 per 100,000 (95%CI: 2097.0-2263.7) for RACF residents and 390 per 100,000 (95%CI 384.8-395.8) for older people living in the community. The hospitalisation rate for RACF residents was estimated to decline by 2.9% annually (95%CI: - 4.3 to - 1.5). Hospital treatment cost for hip fractures was AUD$958.5 million. Compared to older people living in the community, a higher proportion of RACF residents were aged ≥ 90 years (36.1% vs 17.2%), were female (75.3% vs 71.8%), had > 1 Charlson comorbidity (37.6% vs 35.6%) and 58.2% had dementia (vs 14.4%). RACF residents had fewer in-hospital rehabilitation episodes (18.7% vs 60.9%) and a higher proportion of unplanned readmissions (10.6% vs 9.1%) and in-hospital mortality (5.9% vs 3.3%) compared to older people living in the community. CONCLUSIONS RACF residents are a vulnerable cohort of older people who experience worse health outcomes and survival post-hip fracture than older people living in the community. Whether access to individualised hip fracture rehabilitation for RACF residents could improve their health outcomes should be examined.

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
PURPOSE The aim of this study was to determine whether there has been a change in the mean age and age-standardized incidence of minimal trauma hip fractures in the Newcastle and Lake Macquarie population of Australia between 1998 and 2015. METHOD Patients with neck of femur fractures over 50 who presented to the regional referral centre were retrospectively identified using the ICD-9 and ICD-10 coding system. RESULTS There were 233 and 308 eligible patients in 1998 and 2015, respectively. For females, the mean age for hip fracture of 83.2 years in 1998 was not significantly different from the mean age of 84.5 years in 2015 (P = .16). For males, the mean age for hip fracture was significantly older at 84.6 years in 2015 compared to 80.4 years in 1998 (P = .005). For females, the decrease in the rate of hip fracture from 1998 to 2015 was 13% and was weakly statistically significant (IRR = 0.86, P = .05). For males, there was a statistically significant decrease in the rate of hip fractures from 1998 to 2015 by 33% (IRR = 0.67, P = .001). CONCLUSION Our study shows a decrease in age-standardized rates of hip fractures for men and women and suggests that men are demonstrating a greater improvement in bone health compared to women.

Abstract
Fatal falls are frequent and seem to be an increasing problem in the elderly. Especially ground level falls (GLFs) and falls on or from stairs and steps (stairs falls) are worth examining for forensic classification and in order to improve the development of preventive measures. We retrospectively analyzed 261 fatal falls of elderly age 65 + years, which were autopsied at the Institute of Legal Medicine in Munich between 2008 and 2014. After careful screening, the sub-set of all 77 GLFs and 39 stairs falls were analyzed towards socio-demographic characteristics, fall circumstances, injuries, and circumstances of death. A subsequent analysis of GLF cases regarding the presence of proximal femur fractures (PFF) was performed. The injury pattern of the GLFs and the stairs falls clearly differ with a higher share of injuries to the lower extremities in the GLFs. However, the most severely injured body region was the head in both groups (62% of the stairs cases, 49% of the GLF cases). Alcohol as contributing to the fall was seen more frequently in the stairs falls. PFF were not seen in the stairs falls, but then in 18 GLF cases. Yet, for 17 among them (22% of 77), their hip fracture was the only serious injury leading to hospitalization and death. Only one GLF case was already found dead. This finding indicates a potential of avoiding up to 22% of the GLF fatalities by preventing hip fractures by optimized hip protectors or other measures, especially for the elderly aged 75 + years.

Abstract
Purpose Osteoporosis is asymptomatic morbidity of the elderly which develops slowly over several years. Osteoporosis diagnosis has typically involved Fracture Risk Assessment (FRAX) followed by dual energy X-ray absorptiometry (DXA) in specialist care. Point-of-care pulse-echo ultrasound (PEUS) was developed to overcome DXA-related access issues and to enable faster fracture prevention treatment (FPT) initiation. The objective of this study was to evaluate the cost-effectiveness of two proposed osteoporosis management (POMs: FRAX→PEUS-if-needed→DXA-if-needed→FPT-if-needed) pathways including PEUS compared with the current osteoporosis management (FRAX→DXA-if-needed→FPT-if-needed). Materials and methods Event-based probabilistic cost–utility model with 10-year duration for osteoporosis management was developed. The model consists of a decision tree for the screening, testing, and diagnosis phase and is followed by a Markov model for the estimation of incidence of four fracture types and mortality. Five clinically relevant patient cohorts (potential primary FPT in women aged 75 or 85 years, secondary FPT in women aged 65, 75, or 85 years) were modeled in the Finnish setting. Generic alendronate FPT was used for those diagnosed with osteoporosis, including persistence overtime. Discounted (3%/year) incremental cost-effectiveness ratio was the primary outcome. Discounted quality-adjusted life-years (QALYs), payer costs (year 2016 value) at per patient and population level, and cost-effectiveness acceptability frontiers were modeled as secondary outcomes. Results POMs were cost-effective in all patient subgroups with noteworthy mean per patient cost savings of €121/76 (ranges €107–132/52–96) depending on the scope of PEUS result interpretation (test and diagnose/test only, respectively) and negligible differences in QALYs gained in comparison with current osteoporosis management. In the cost-effectiveness acceptability frontiers, POMs had 95%–100% probability of cost-effectiveness with willingness to pay €24,406/QALY gained. The results were robust in sensitivity analyses. Even when assuming a high cost of PEUS (up to €110/test), POMs were cost-effective in all cohorts. Conclusion The inclusion of PEUS to osteoporosis management pathway was cost-effective.

Abstract
BACKGROUND Hip fractures of older adults are a major public health issue. METHODS We determined the current trend in the number and incidence (per 100,000 persons) of hip fracture among older adults in Finland by taking into account all persons 50 years of age or older who were admitted to hospitals for primary treatment of such fracture between 1970 and 2016. RESULTS The number of hip fractures rose sharply till the end of 1990s (from 1857 in 1970 to 7122 in 1997), but since then, the rise has slowed down (7716 fractures in 2016). Similarly, the age-adjusted incidence of hip fracture increased until 1997 but declined thereafter. The decline was especially clear in women whose age-adjusted incidence was 537.9 (per 100,000 persons) in 1997 but only 344.1 in 2016. In men, the corresponding incidence was 256.5 in 1997 and 194.7 in 2016. With the current 2016 incidence rates, the number of hip fractures in Finland will increase by 44% by the year 2030 due to the sharp growth of the population at risk. The only way to limit the rise is to have a further decline in fracture incidence in 2016-2030. CONCLUSIONS The decline in the incidence of hip fracture in Finland has continued through the entire new millennium. Despite this we have to effectively continue implementation of the fracture prevention efforts, because our elderly population will grow rapidly in the near future.

Abstract
Background and purpose - While development in hip fracture incidence and mortality is well examined, none has yet looked at the temporal trends regarding prevalence of co-morbidities. Therefore we investigated changes in incidence of first hip fracture, co-morbidity prevalence, 30 day- and 1-year mortality in hip fracture patients in the Danish population during the period 1999 to 2012. Patients and methods - Patients >18 years admitted with a fractured hip in Denmark between 1996 and 2012 were identified with data for the period 1999-2012 being analyzed regarding prevalence of co-morbidities, incidence, and mortality. Results - 122,923 patients were identified. Incidence in the whole population declined but sex-specific analysis showed no changes for men. For the whole study population, 30-day and 1-year mortality remained unchanged. Age at time of first hip fracture also remained unchanged. Of the included co-morbidities a decrease in prevalence of malignancy and dementia in women was found while there was an increase in the prevalence of all remaining co-morbidities, except hemi- or paraplegia for both sexes, rheumatic diseases for women, and for men diabetes with complications, myocardial infarction, AIDS/HIV, and malignancy. Interpretation - While hip fracture incidence declined for women it was unchanged for men; likewise, 30-day and 1-year mortality rates together with age at first fracture remained unchanged. When these results are compared with the relatively large increase in the prevalence of co-morbidities, it does not seem likely that the increased disease burden is affecting either the incidence or the mortality.

Abstract
Hypovitaminosis D is a problem among hip fracture patients. In a 1-year cohort study comprising 245 hip fracture patients (mean age of females 81 years and males 78 years) from south-eastern Finland, the mean 25-hydroxyvitamin D [S-25(OH)D] concentration was 73(SD 31) nmol/L. Vitamin D supplementation has been integrated into our current practice. INTRODUCTION The objectives of this study are to verify vitamin D levels among hip fracture patients and to compare the results with a similar study conducted in the same two hospitals covering the same geographic area 12 years ago. METHODS A prospective cohort comprising 245 Caucasian hip fracture patients was enrolled in the study in two acute hospitals in south-eastern Finland (61° N) over a 12-month period in 2015-2016. The S-25(OH)D was measured using 25-hydroxyvitamin D electrochemiluminescence binding assay. The S-25(OH)D concentrations were compared with the corresponding concentrations of a similar cohort analyzed in the same two hospitals 12 years ago. RESULTS Of the 245 patients, 70% were women with a mean age of 81 (SD 10) years, while the men had a mean age of 78 (SD 12) years (p < 0.01). The total mean S-25(OH)D concentration was 73 (SD 31.3) nmol/L. Regional differences were found: 15% in hospital A and 36% in hospital B had a S-25(OH(D level < 50 nmol/L, and the mean S-25(OH)D level was 79.2 (SD 31.7) nmol/L in hospital A and 62.4 (SD 27.5) nmol/L in hospital B (p < 0.001). No differences were found in S-25(OH)D concentrations by either the place of residence or the time of year. Overall, the percentage of patients with a sufficient vitamin D level (> 50 nmol/L) was remarkably higher in 2015-2016 (77%) than in 2003-2004 (22%). CONCLUSION Our results indicate that vitamin D supplementation has been widely integrated into our current practice. However, regional differences were found in the S-25(OH)D concentrations for which the reasons are unknown.

Abstract
BACKGROUND Fall-induced injuries in elderly people are a growing public health issue. AIM We aimed to determine the current trends in the fall-induced severe wounds and lacerations among older adults in Finland-an EU country with a well-defined Caucasian population of 5.5 million. METHODS The injury trends were assessed by taking into account all persons 80 years of age or older who were admitted to Finnish hospitals for primary treatment of these injuries during 1970-2014. RESULTS The number of fall-induced severe wounds and lacerations among 80-year-old or older Finnish adults showed a sharp increase during the 44-year follow-up, from 52 in 1970 to 1393 in 2014. The age-adjusted incidence of injury (per 100,000 persons) also showed a clear rise from 1970 to 2014: from 98.3 to 511.5 in women, and from 92.0 to 395.3 in men. In both sexes, the increase was greatest in the oldest age group (persons 90 years of age or older). CONCLUSIONS The number of fall-induced severe wounds and lacerations among older Finnish persons rose in 1970-2014 with a rate that could not be explained merely by demographic changes. Further studies should focus on detailed understanding of the reasons for the rise and assessing possibilities for fall and injury prevention.

Abstract
The purpose of this study was to estimate the current economic burden of osteoporosis in South Korea using national claim data of the Korean National Health Insurance Service (KNHIS) from 2008 to 2011. Patients aged 50 years or older were identified from KNHIS nationwide database for all records of outpatient visits or hospital admissions. Healthcare costs for osteoporotic patients included direct medical costs for hospitalization, outpatient care, and prescription drugs for the year after discharge. Healthcare costs were estimated based on the perspective of KNHIS, and calculated using a bottom-up approach. Between 2008 and 2011, total healthcare costs for osteoporotic patients increased from 3976 million USD to 5126 million USD, with an annual increase of 9.2% which accounted for one-sixth (16.7%) of national healthcare expenditure. Healthcare cost for hospitalization was the highest ($1903 million, 40.0% of total healthcare cost), followed by cost for outpatient care ($1474 million, 31.0%) and cost for prescription drugs ($1379 million, 29.0%). Although total healthcare cost for osteoporotic men was 6 times lower than that for osteoporotic women, the cost per person was 1.5 times higher than that for women. Total healthcare cost for osteoporotic patients without fractures was higher than that for osteoporotic patients with fractures. However, cost per person was the opposite. Osteoporosis entails substantial epidemiologic and economic burden in South Korea. This study provides information about the total healthcare burden, which could be important when determining what attention and awareness osteoporosis should be given in the public health system.

Abstract
Background Low-trauma fractures of elderly women are a major public health concern. Methods We determined the current trend in the absolute number and incidence (per 100,000 persons) of fresh low-trauma fractures of the proximal humerus among 80-year-old or older Finnish women by taking into account all women who were admitted to Finnish hospitals for primary treatment of such a fracture between 1970 and 2015. Results The number of low-trauma fractures of the proximal humerus among 80-year-old or older Finnish women rose continuously between 1970 (32 fractures) and 2015 (568 fractures), whereas the age-adjusted fracture rate (showing a clear rise from 87 fractures per 100,000 persons in 1970 to 304 fractures in 1995) became stabilized between 1995 and 2015 (297 fractures per 100,000 persons in 2015). Conclusions The clear rise in the incidence of low-trauma proximal humeral fractures in Finnish elderly women from early 1970s until mid 1990s has been followed by stabilized fracture rates. Reasons for this are largely unknown, but a cohort effect toward a healthier aging population with improved functional ability, as well as measures to prevent falls and alleviate fall severity, could partly explain the phenomenon.

Abstract
PURPOSE Information on the incidence of acetabular fractures of the pelvis is limited. Epidemiological data is often based on specific trauma registers, individual trauma centres or on trends of all pelvic fractures grouped together. The primary aim of this study was to determine the incidence and trends of hospital-treated acetabular fractures in the Finnish population from 1997 to 2014. The secondary aim was to assess the trauma mechanisms involved. METHODS The Finnish National Hospital Discharge Register collects inpatient data from all public and private medical institutions in Finland and covers the entire Finnish population of 5.5 million. For this study, we selected all persons 18 years of age or older who were admitted to hospital for the treatment of an acetabular fracture between 1997 and 2014. The main outcome variable was the annual number of patients hospitalised with a main or secondary diagnosis of acetabular fracture of the pelvis. RESULTS The overall crude incidence of acetabular fractures increased slightly (from 6.4/100 000 persons/year to 8.1/100 000 persons/year) from 1997 to 2014 while the age-standardised incidence rate remained at a similar level (7.1/100 000/persons/year in 1997 and 7.2/100 000/persons/year in 2014). An incidence increase was observed in the elderly population, whereas the incidence of acetabular fractures in the younger population (mostly high energy traumas) remained stable. The most frequent trauma mechanism for acetabular fractures was fall on the same level (47%). CONCLUSIONS The incidence of acetabular fractures increased slightly in Finland between 1997 and 2014. This increase was observed especially in the elderly population and the ageing of the population largely explains the rise. The incidence of acetabular fractures in the younger population decreased. The most common trauma mechanism was falling on the same level.

Abstract
INTRODUCTION Pedestrian falls (PFs) - falls in public spaces without collisions with other road users - are a significant cause of serious transport-related injuries, amounting to three-quarters of all pedestrians admitted to hospital. METHODS This scoping review examined peer-reviewed research on PFs published between 1995 and 2015. Electronic databases (Scopus, SafetyLit, and PubMed) were used to find studies identifying PFs or outdoor falls (the latter also including falls in gardens). RESULTS We identified only 28 studies reporting relevant information on PFs (i.e., 15 prospective, 10 retrospective, and 3 intervention studies). The results show that more walking is related to a lower risk of PFs. Older people, especially older women, have a higher risk of (injurious) PFs. Outdoor fall victims have equally good or better health characteristics and scores on balance tests compared to those who have not experienced such falls. Road factors such as uneven surfaces, busy junctions, stairs, and slippery surfaces seem to play an important role in PFs, but much of the research on these factors is of a qualitative nature. CONCLUSIONS PF victims are generally in good health (apart from normal age-related problems) but at risk due to road factors. PRACTICAL APPLICATIONS We recommend to adopt a human factors approach. The road system should be adapted to human capabilities and limitations including those of pedestrians. Measures such as preventing uneven surfaces and good winter maintenance seem to be effective. However, we advise more quantitative research on road factors to inform design guidelines and standards for public space authorities given the qualitative nature of current research on road factors.

Abstract
OBJECTIVE Dietary quality in relation to bone health has been analysed in relatively few studies. The current study aimed to assess the association of the Baltic Sea diet (BSD) and the Mediterranean diet (MD) with bone mineral density (BMD) among elderly women. DESIGN Lumbar, femoral and total body BMD were measured by dual-energy X-ray absorptiometry at baseline and year 3. Dietary intake was measured by 3 d food record at baseline. BSD and MD scores were calculated from food and alcohol consumption and nutrient intake. Information on lifestyle, diseases and medications was collected by questionnaires. Longitudinal associations of BSD and MD scores with BMD were analysed using linear mixed models. SETTING Interventional prospective Kuopio Osteoporosis Risk Factor and Fracture Prevention study including women aged 65-71 years and residing in Kuopio province, Finland. SUBJECTS Women (n 554) with mean age of 67·9 (sd 1·9) years and mean BMI of 28·8 (sd 4·7) kg/m2. RESULTS Higher BSD scores were associated with higher intakes of fruit and berries, vegetables, fish and low-fat dairy products, and lower intake of sausage. Higher MD scores were associated with higher consumption of fruit and berries and vegetables. BSD and MD scores were associated with higher PUFA:SFA and higher fibre intake. Femoral, lumbar or total body BMD was not significantly different among the quartiles of BSD or MD score. CONCLUSION The lack of associations suggest that Baltic Sea and Mediterranean dietary patterns may not adequately reflect dietary factors relevant to bone health.

Abstract
Qualitative similarities between hip fracture trends in different countries suggests variations of the same epidemic. We tested a single statistical shape to describe time trends in Europe, while allowing for country-level variability. Using data from 14 countries, we modelled incidence rates over time using linear mixed-effects models, including the fixed effects of calendar year and age. Random effects were tested to quantify country-level variability in background rates, timing of trend reversal and tempo of reversal. Mixture models were applied to identify clusters of countries defined by common behavioural features. A quadratic function of time, with random effects for background rates and timing of trend reversal, adjusted well to the observed data. Predicted trend reversal occurred on average in 1999 in women (peak incidence about 600 per 100 000) and 2000 in men (about 300 per 100 000). Mixture modelling of country-level effects suggested three clusters for women and two for men. In both sexes, Scandinavia showed higher rates but earlier trend reversals, whereas later trend reversals but lower peak incidences were found in Southern Europe and most of Central Europe. Our finding of a similar overall reversal pattern suggests that different countries show variations of a shared hip fracture epidemic.

Kannus P, Niemi S, Sievänen H, Parkkari J. Continuous decline in incidence of distal humeral fracture of older women in Finland. Aging Clin Exp Res 2017; 29:467-471.

Abstract
BACKGROUND Low-trauma fractures (also called osteoporotic fragility fractures or fall-induced fractures) of older adults are a serious public health problem. However, very little population-based information is available on the nationwide numbers, incidences, and especially secular trends of elderly people's low-trauma fractures of the distal humerus. METHODS We assessed the current trends in the number and incidence of these fractures in 60-year-old or older women in Finland by taking into account all women who were admitted to Finnish hospitals for primary treatment of such fracture in 1970-2014. RESULTS The annual number of low-trauma distal humeral fractures among Finnish women 60 years of age or older rose over fivefold between 1970 and 1998 (from 42 to 224 fractures), but thereafter, the number decreased down to 198 fractures in 2014. The age-adjusted incidence (per 100,000 persons) of these fractures also increased in 1970-1998 (from 12 to 35) but decreased thereafter to 23 in 2014. The finding was similar in the age-specific patient groups (60-69, 70-79, and 80+): The incidence rose from 1970 till 1998 and decreased thereafter. CONCLUSIONS The steep rise in the rate of low-trauma distal humeral fractures in 60-year-old or older Finnish women from 1970 till late 1990s has been followed by a clearly declining fracture rate. The exact reasons for this secular change are unknown, but a cohort effect toward improved functional ability among elderly women, as well as measures to prevent falls and alleviate fall severity, could partly explain the phenomenon.

Abstract
Objectives to describe the secular trend and seasonal variation in the incidence of hip fracture (HF) over 12 years (2003-2014) in Catalonia, the community with the highest incidence of HF in Spain. Methods data about age, gender, type of fracture and month of hospitalisation among patients aged 65 years and older discharged with a diagnosis of HF were collected. Crude and age-standardised annual incidence rate were reckoned. To analyse HF trend, the age/sex-adjusted average annual change in incidence (incidence rate ratio, IRR) was calculated. Results we identified 100,110 HF in the period, with an increase of 16.9% (women 13.4%; men 28.4%). Trochanteric fractures were the most frequent (55.8%). The crude incidence rate (per 100,000 population) decreased from 677.2 (95% confidence interval (95% CI) 662.0-692.7) to 657.6 (95% CI 644.0-671.5). The standardised incidence rate decreased from 754.0 (95% CI 738.6-769.3) to 641.5 (95% CI 627.7-655.3), with a sharp decrease in women (-16.8%) while it was stable in men. The incidence by type of fracture was stable. The trend throughout the period showed a slight decrease with IRR 0.99 (95% CI 0.98-0.99; P = 0.025). The incidence was stable in the oldest group (+85 years), while there was a downward trend in the younger groups. A significant seasonal pattern was observed, with more cases in winter and less in summer (spring as reference). Conclusions the secular trend reveals a decreasing incidence of HF although the absolute number has increased in the last 12 years in Catalonia. Trochanteric fractures were the most prevalent and a seasonal pattern was observed, with more cases in winter.

Abstract
BACKGROUND Traumatic brain injury constitutes a persistent health problem among pediatric populations worldwide and is often referred to as a silent epidemic. There remains a paucity of scientific exploration with regard to understanding the ecological risk profiles of well-defined populations. In Finland, the healthcare system covers all hospitals, provides uniform access to care and has a universal surveillance system that allows for epidemiological examination of a wide variety of health issues. The present study aims to clarify the incidence, type and geographical presentation of pediatric TBI in Finland. METHODS We utilized the National Hospital Discharge Register (NHDR) to prospectively identify all new cases of TBI among persons aged 18 years or younger between 1998 and 2012. Incidence rates were computed as average annual rates per 100,000 person years (py). RESULTS During the study period 1998-2012, 21,457 children and adolescents were hospitalized for TBI. The cumulative incidence rate for the entire period was 99/100,000. Males were approximatively 1.5 times more likely to have sustained a TBI and had consistently higher rates during each year under study. Concussions were the most common form of TBI (92.9/100,000 person years), with diffuse brain injuries being the second most common (8.7/100,000 py). Diagnostic trends differed markedly with southern Finland experiencing the lowest rates of TBI when adjusted for population size. CONCLUSIONS TBI are serious and potentially disabling conditions. The elevated levels of pediatric TBI in Finland warrant increased attention.

Abstract
UNLABELLED Proximal humeral fracture is the third most common osteoporotic fracture. To our knowledge, this is the first nationwide population-based registry study in adults that includes both inpatient and outpatient visits. Thus, we were able to report the true incidence rates and trends in the treatment of proximal humeral fractures. INTRODUCTION Proximal humeral fractures are among the most common osteoporotic fractures. Valid epidemiologic population-based data, including both inpatient and outpatient visits, however, are lacking. METHODS To investigate the Swedish national incidence rates and treatment trends of proximal humeral fractures, we obtained data from the Swedish Hospital Discharge Register between 2001 and 2012. All adult patients (≥18 years of age) in the Swedish Hospital Discharge Register were included. Outpatient visits have been included in the register since 2001. RESULTS We identified 98,770 patients (women n = 72,063; 73 %) with proximal humeral fractures between 2001 and 2012. In 2001, the sex-specific incidence of proximal humeral fractures was 134.5 per 100,000 person-years for women and 49.2 for men. In 2012, the corresponding values were 174.6 for women and 68.1 for men, increasing 30 % in women and 39 % in men. A total of 17,013 surgical procedures were conducted between 2001 and 2012. Open reduction and internal fixation with a plate was the most common procedure (n = 5050, 30 %), followed by endoprosthetic implantation (n = 3962, 23 %) and intramedullary nailing (n = 3376, 20 %). The proportion of surgically treated patients increased from 12.1 % in 2001 to 16.8 % in 2012 for women and from 15.1 % in 2001 to 17.1 % in 2012 for men. CONCLUSION The Swedish national incidence of proximal humeral fractures has been increasing, although it seems to have peaked in the elderly population during 2008-2010. The rate of surgical treatment has increased substantially, particularly open reduction and internal fixation with a plate. To our knowledge, this is the first nationwide epidemiologic study for Sweden reporting the incidence of proximal humeral fractures and including all inpatient and outpatient visits.

Abstract
BACKGROUND Various fall-induced injuries in older adults are a major public health problem. AIM We aimed to assess the current trends in the fall-induced severe maxillofacial injuries among older adults in Finland, an EU country with a well-defined white population of 5.5 million. METHODS The injury trends were determined by taking into account all persons 60 years of age or older who were admitted to Finnish hospitals for primary treatment of these injuries between 1999 and 2014. RESULTS The number of fall-induced maxillofacial injuries among older Finnish adults doubled during the 16-year follow-up, from 434 in 1999 to 981 in 2014. The age-adjusted incidence of injury (per 100 000 persons) also showed a clear increase from 1999 to 2014: from 47.4 to 71.3 in women, and from 39.2 to 59.6 in men. In both sexes, the increase was most prominent in the oldest age group, persons aged 80 years or older. CONCLUSIONS The number of fall-induced severe maxillofacial injuries among older Finns rose considerably between 1999 and 2014-with a rate that could not be explained merely by demographic changes. Further studies are urgently needed to better assess the reasons for the rise and possibilities for injury prevention.

Abstract
UNLABELLED Hip fractures place a large burden on healthcare and determining the variation in incidence is important to plan resources. We found, in Northern Ireland, that the age-related incidence for women is declining but the incidence for men and the total number of fractures remains static as the elderly population increases. INTRODUCTION Hip fractures place a significant burden on healthcare systems throughout the world. Recent studies have shown that the incidence is starting to decline or plateau. We aimed to study the incidence of hip fractures in 2001 and 2011 within Northern Ireland and hope to guide further service provision. METHODS The years 2001 and 2011 were selected as accurate census population data was available. The Hospital Inpatient System (HIS) database was used to collect the data and the search was carried out by a statistician using ICD codes S72.0 and S72.1. RESULTS The total incidence of hip fractures in the population aged 50 and over fell from 358 per 100,000 to 274 per 100,000. In females, the incidence fell from 513 to 412 per 100,000. In males, the incidence increased from 172 to 178 per 100,000. The total number of hip fractures remained static (1737 in 2001 and 1739 in 2011) as a result of an increase in the elderly population. Incidence and total number of femoral neck fractures (S72.0) declined while the incidence and total number of pertrochanteric fractures (S72.1) increased. CONCLUSIONS Our results are in keeping with the declining trend in hip fracture incidence in many Western countries, though we found that this is only true for women. The exact reasons for this remain unclear but are likely to be multifactorial. In the future, the number of fractures may increase further given the increasingly elderly population and further provision particularly for patients with pertrochanteric fractures will be required. Increased awareness, diagnosis and treatment of males with osteoporosis should be prioritised.

Abstract
In January 2005, the National Institute for Health and Care Excellence (NICE) in England and Wales provided new guidance on the use of antiosteoporosis therapies for the secondary prevention of osteoporotic fractures. This was shortly followed in the same year by market authorization of a generic form of alendronic acid within the UK. We here set out to estimate the actual practice impact of these events among hip fracture patients in terms of antiosteoporosis medication prescribing and subsequent fracture incidence using primary care data (Clinical Practice Research Datalink) from 1999 to 2013. Changes in level and trend of prescribing and subsequent fracture following publication of NICE guidance and availability of generic alendronic acid were estimated using an interrupted time series analysis. Both events were considered in combination within a 1-year "intervention period." We identified 10,873 primary hip fracture patients between April 1999 and Sept 2012. Taking into account prior trend, the intervention period was associated with an immediate absolute increase of 14.9% (95% CI, 10.9 to 18.9) for incident antiosteoporosis prescriptions and a significant and clinically important reduction in subsequent major and subsequent hip fracture: -0.19% (95% CI, -0.28 to -0.09) and -0.17% (95% CI, -0.26 to -0.09) per 6 months, respectively. This equated to an approximate 14% (major) and 22% (hip) reduction at 3 years postintervention relative to expected values based solely on preintervention level and trend. We conclude that among hip fracture patients, publication of NICE guidance and availability of generic alendronic acid was temporally associated with increased prescribing and a significant decline in subsequent fractures. © 2016 American Society for Bone and Mineral Research.

Abstract
Background Institutionalization after hip fracture is a socio-economical burden. We examined the predictive value of Instrumental Activities of Daily Living (IADL) and Mini Mental State Examination (MMSE) for institutionalization after hip fracture to identify patients at risk for institutionalization. Methods Fragility hip fracture patients ≥65 years of age (n = 584) were comprehensively examined at a geriatric outpatient clinic 4 to 6 months after surgery and followed 1 year postoperatively. A telephone interview with a structured inquiry was performed at 1, 4, and 12 months after hip fracture. Results Age-adjusted univariate logistic regression analysis revealed that IADL and MMSE scores measured at the outpatient clinic were significantly associated with living arrangements 1 year after hip fracture. Multivariate logistic regression analysis established that institutionalization 1 year after hip fracture was significantly predicted by institutionalization at 4 months (odds ratio [OR] 16.26, 95 % confidence interval [CI] 7.37–35.86), IADL <5 (OR 12.96, 95 % CI 1.62–103.9), and MMSE <20 (OR 4.19, 95 % CI 1.82–9.66). A cut-off value of 5 was established for IADL with 100 % (95 % CI 96 %–100 %) sensitivity and 38 % (95 % CI 33 %–43 %) specificity and for MMSE, a cut-off value of 20 had 83 % (95 % CI 74 %–91 %) sensitivity and 65 % (95 % CI 60 %–70 %) specificity for institutionalization. During the time period from 4 to 12 months, 66 (11 %) patients changed living arrangements, and 36 (55 %) of these patients required more supportive accommodations. Conclusion IADL and MMSE scores obtained 4 to 6 months after hospital discharge may be applicable for predicting institutionalization among fragility hip fracture patients ≥65 years of age at 1 year after hip fracture. An IADL score of ≥5 predicted the ability to remain in the community. Changes in living arrangements also often occur after 4 months.

Declining incidence of fall-induced ankle fractures in elderly adults: Finnish statistics between 1970 and 2014. Arch Orthop Trauma Surg 2016; 136:1243-1246. [PMID: 27443166 DOI: 10.1007/s00402-016-2524-7] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/03/2016] [Indexed: 02/09/2023]
Abstract
BACKGROUND Fall-induced fractures of older adults are a major public health concern. However, nationwide information on recent fracture trends is sparse. METHODS We determined the trend in the number and incidence (per 100,000 persons) of fall-induced ankle fractures among older adults in Finland by taking into account all persons 60 years of age or older who were admitted to Finnish hospitals for primary treatment of such fracture in 1970-2014. RESULTS The number of fall-induced ankle fractures among 60-year-old or older Finnish persons increased steadily and sharply between 1970 (369 fractures) and 1997 (1668 fractures), but since then, the increase has slowed down (1835 fractures in 2014). The raw incidence of ankle fracture, showing a clear rise from 57 fractures per 100,000 persons in 1970 to 169 fractures in 1997, declined steadily between 1997 and 2014 (to 126 fractures in 2014). Observations on the age-adjusted fracture incidence were similar. During 1970-1997, the age-adjusted incidence of fall-induced ankle fracture clearly rose in both women and men, but thereafter, the incidence declined; in women, from 199 in 1997 to 158 in 2014, and in men, from 123 in 1997 to 80 in 2014. CONCLUSIONS The sharp rise in the incidence of fall-induced ankle fracture in Finnish older adults from early 1970s until late 1990s has been followed by a declining fracture rate. Despite this welcome development, the rapid aging of our population is likely to increase the absolute number of these fractures in the near future, and therefore, large-scale fracture-preventing intervention studies are urgently needed.

Low-trauma knee fractures in older Finnish women between 1970 and 2013. Aging Clin Exp Res 2016; 28:665-8. [PMID: 26403684 DOI: 10.1007/s40520-015-0457-6] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2015] [Accepted: 09/15/2015] [Indexed: 10/23/2022]
Abstract
BACKGROUND Fresh information on various low-trauma fractures of elderly adults is sparse. AIM We aimed to assess the current trends in the low-trauma knee fractures among older adults in Finland, an EU country with a well-defined white population of 5.4 million. METHODS The rates of elderly Finns' low-trauma fractures of the knee (distal femur, patella, and proximal tibia) were assessed by taking into account 60-year-old or older persons who were admitted to Finnish hospitals for primary treatment of such injury in 1970-2013. RESULTS The incidence of low-trauma knee fractures among 60-year-old or older Finnish women sharply rose between 1970 and 1997, from 55 fractures (per 100,000 persons) in 1970 to 124 fractures in 1997. Thereafter, the incidence continuously declined so that the fracture incidence was 91 in 2013. The corresponding age-adjusted fracture incidences were 60 (1970), 119 (1997), and 83 (2013). In older men, the fracture incidence was rather steady over time: the age-adjusted incidence was 30 in 1970 vs. 28 in 2013. CONCLUSIONS The rise in the incidence of low-trauma knee fractures in Finnish older women from early 1970s until late 1990s has been followed by a continuous decline in the fracture rate. Reasons for the decline are unknown, but a cohort effect toward a healthier aging female population with improved functionality and decreased risk of injurious slips, trips, and falls could partly explain the observation.

Abstract
UNLABELLED Incidence of hip fracture increased in Korean populations over age 50 between 2008 and 2012, and the number of fractures was predicted to increase by 1.4 times by 2025. This is important information for public health planning. INTRODUCTION The purposes of this study were to evaluate the trends in the incidence and mortality of hip fracture between 2008 and 2012 and predict the number of hip fractures in Korea through 2025 using nationwide claims data. METHODS The data managed by the National Health Insurance Service were used to identify the hip fractures in patients aged >50 years between 2008 and 2012. Projections of hip fractures were conducted using the Poisson distribution from 2016 to 2025 in Korea. RESULTS The incidence of hip fractures (per 100,000) increased by 14.1 % over the 5 years of the study, by 15.8 % in women and 10.9 % in men; the older age group showed a steep rise and shift in the incidence from 2008 to 2012. The cumulative mortality rates at 1 year after hip fractures were 17.2 % (3575/20,849) in 2008 and 16.0 % (4547/28,426) in 2012. Overall standardized mortality ratios (SMRs) for hip fracture were higher in men (11.93) than in women (11.22) and were higher than those in the general population in all age groups. In 2016, the total number of hip fractures was estimated to increase an overall of 1.4 times by 2025. CONCLUSIONS The incidence of hip fracture continues to increase, and the related mortality is still high, although it has decreased over time. The socioeconomic burden of hip fracture is expected to increase in Korea along with the increased estimated number of fractures. Nationwide strategies should include attempts to reduce the future socioeconomic burdens of hip fractures.

Abstract
BACKGROUND There is evidence that fat mass is correlated with bone mineral density (BMD) in inflammatory bowel disease (IBD), but data on the role of adipokines on this association are limited. The aim of this study was to investigate the serum levels of chemerin, visfatin, and vaspin, hormones that act as adipokines, in relation to BMD in patients with ulcerative colitis (UC) and Crohn's disease (CD). PATIENTS AND METHODS Serum from 120 IBD patients (68 CD, 52 UC) and 98 matched healthy controls (HC) was collected. Chemerin, visfatin, and vaspin levels were assessed using an enzyme-linked immunosorbent assay. BMD was determined for the lumbar spine and the proximal femur using dual-energy X-ray absorptiometry. Full-body composition scans were analyzed using enCORE software based on the absorptiometry system. RESULTS Serum chemerin was higher in IBD patients than HC [CD 13.67.1±5.8, UC 13.9±4.3 vs. HC 7.8±2.6 ng/ml, odds ratio (OR): 0.95, 95% confidence interval (CI) 0.93-0.98, P<0.0001]. Serum visfatin levels in CD patients were significantly higher than those in UC patients (9.3±14.01 vs. 6.5±7.2 ng/ml, OR: 0.86, 95% CI 0.80-0.92, P=0.039). In multivariate logistic regression analysis, a significant independent association of osteoporosis (T-score ≤2.5 SD) with age (OR: 1.04, 95% CI 1.01-1.08, P=0.02), visfatin (OR: 0.78, 95% CI 0.63-0.97, P=0.02), and chemerin levels (OR: 0.83, 95% CI 0.70-0.98, P=0.03), but not with BMI or body composition, was found. CONCLUSION Serum visfatin and chemerin levels are associated with the development of osteoporosis in IBD. These results suggest a role of visfatin and chemerin in the pathophysiology of osteoporosis in IBD.

Abstract
UNLABELLED We estimated the number of hip fracture patients in 2012 in Japan and investigated the trends in incidence during a 25-year period from 1987 to 2012. Despite the increasing number of patients, the incidence of hip fracture in both men and women aged 70-79 years showed the possibility of decline. INTRODUCTION The objectives of this study were to estimate the number of hip fracture patients in 2012, to investigate the trends in incidence during a 25-year period from 1987 to 2012, and to determine the regional differences in Japan. METHODS Data were collected through a nationwide survey based on hospitals by a mail-in survey. Hip fracture incidences by sex and age and standardized incidence ratios by region were calculated. RESULTS The estimated numbers of new hip fracture patients in 2012 were 175,700 in total (95 % CI 170,300-181,100), 37,600 (36,600-38,600) for men and 138,100 (134,300-141,900) for women. The incidence rates in both men and women aged 70-79 years were the lowest in the 20-year period from 1992 to 2012. The incidence was higher in western areas of Japan than that in eastern areas in both men and women; however, the difference in the incidence of hip fracture between western and eastern areas is becoming smaller. CONCLUSIONS Despite the increasing number of new patients, the incidence of hip fracture in both men and women aged 70-79 years showed the possibility of decline. The exact reasons for this are unknown, but various drugs for improving bone mineral density or preventing hip fracture might have influenced the results. A decrease in the differences in nutrient intake levels might explain some of the change in regional differences in Japan.

Abstract
UNLABELLED This study assessed the cost-effectiveness of vitamin D supplementation and exercise, separately and combined, in preventing medically attended injurious falls among older home-dwelling Finnish women. Given a willingness to pay of €3,000 per injurious fall prevented, the exercise intervention had an 86 % probability of being cost-effective in this population. INTRODUCTION The costs of falling in older persons are high, both to the individual and to society. Both vitamin D and exercise have been suggested to reduce the risk of falls. This study assessed the cost-effectiveness of vitamin D supplementation and exercise, separately and combined, in preventing medically attended injurious falls among older Finnish women. METHODS Economic evaluation was based on the results of a previously published 2-year randomized controlled trial (RCT) where 409 community-dwelling women aged 70 to 80 years were recruited into four groups: (1) no exercise + placebo (D-Ex-), (2) no exercise + vitamin D 800 IU/day (D+Ex-), (3) exercise + placebo (D-Ex+), and (4) exercise + vitamin D 800 IU/day (D+Ex+). The outcomes were medically attended injurious falls and fall-related health care utilization costs over the intervention period, the latter evaluated from a societal perspective based on 2011 unit costs. Incremental cost-effectiveness ratios (ICER) were calculated for the number of injurious falls per person-year prevented and uncertainty estimated using bootstrapping. RESULTS Incidence rate ratios (95 % CI) for medically attended injurious falls were lower in both Ex+ groups compared with D-Ex-: 0.46 (0.22 to 0.95) for D-Ex+, 0.38 (0.17 to 0.81) for D+Ex+. Step-wise calculation of ICERs resulted in exclusion of D+Ex- as more expensive and less effective. Recalculated ICERs were €221 for D-Ex-, €708 for D-Ex+, and €3,820 for D+Ex+; bootstrapping indicated 93 % probability that each injurious fall avoided by D-Ex+ per person year costs €708. At a willingness to pay €3,000 per injurious fall prevented, there was an 85.6 % chance of the exercise intervention being cost-effective in this population. CONCLUSIONS Exercise was effective in reducing fall-related injuries among community-dwelling older women at a moderate cost. Vitamin D supplementation had marginal additional benefit. The results provide a firm basis for initiating feasible and cost-effective exercise interventions in this population.

Abstract
BACKGROUND Hip fractures require operation within 36-48 h, and they are most common in the elderly. A high International Normalized Ratio should be corrected before surgery. In the current study, we analyzed the budget impact of various warfarin reversal approaches. METHODS Four reversal strategies were chosen for the budget impact analysis: the temporary withholding of warfarin, administration of vitamin K, fresh frozen plasma (FFP), and a four-factor prothrombin complex concentrate (PCC). RESULTS We estimated that, annually, 410 hip fracture patients potentially require warfarin reversal in Finland. The least costly treatment was vitamin K, which accounted for €289,000 in direct healthcare costs, and the most costly treatment option was warfarin cessation, which accounted for €1,157,000. In the budget impact analysis, vitamin K, PCC and FFP would be cost-saving to healthcare compared with the current treatment mix. CONCLUSION The various warfarin reversal strategies have different onset times, which may substantially impact the subsequent healthcare costs.
