Abstract
BACKGROUND Postmenopausal women are at risk of fall and fracture with the physical decline. Distal radius fracture (DRF) is considered as the primary fragility fracture, and women with this fracture showed poor results in the usual Timed Up-and-Go (TUG) test, indicating a decline in balance and physical ability. The detailed physical characteristics of female DRF patients have not been extensively examined. RESEARCH QUESTION Is the novel laser TUG system able to detect and analyze the detailed gait characteristics in patients with DRF whose physical ability has tended to decline? METHODS In this cross-sectional case control study, the gait characteristics of 32 female patients with DRF who had undergone surgery were evaluated at 2 weeks postoperatively with a laser TUG system to analyze the detailed leg motion during normal TUG test. Forty-three age- and sex-matched non-fractured women were evaluated by the laser TUG system as controls. Lifestyle and present illness were corrected at the time of TUG measurement. Detailed data during laser TUG in both groups were compared statistically, and odds ratio and thread shod of the fracture was elucidated through a logistic regression analysis. RESULTS DRF patients showed slower speed and had to do more steps to complete the TUG test. Furthermore, asymmetric trajectory and significantly further distance from the marker were observed. Thirteen steps to complete the TUG test was the thread shod of DRF. SIGNIFICANCE Detailed gait characteristics of patients with DRF were detected by the laser TUG system. The gait decline and abnormality could be one of the reasons of consecutive fragility fracture. To prevent secondary fragility fractures, this system can be useful for screening.

Abstract
UNLABELLED In this case-control study, we concluded that women with distal radial fractures who were surgically treated showed lower grip strength and dynamic body balancing than those of controls. These results suggest that measurements of grip strength and dynamic body balance may be useful screening tools to assess future fracture risk. INTRODUCTION Patients with distal radial fractures (DRFs) are at risk of future fragility fractures. However, their physical characteristics and tendencies for falls remain unclear. We aimed to compare the physical characteristics of women with and without distal radial fractures. METHODS We included 128 women with a DRF as their first fragility fracture (fracture group) who underwent surgical treatment. Concurrently, 128 age- and sex-matched participants without a history of fragility fractures were selected as controls (control group). The participants underwent assessments of grip strength and the body balancing ability test. Measurements were taken twice in the fracture group, at 2 weeks and 6 months postoperatively, and once in the control group. The body balancing ability test included the Functional Reach Test, Timed Up and Go test (TUG), 2-Step test (2ST), and Timed Uni-pedal Stance test. The participants also completed questionnaires about their health. RESULTS There were no significant differences (p > 0.05) in patient characteristics between the groups. The fracture group showed lower grip strength across all age groups. In the DRF group, prolonged TUG time was observed at 2 weeks postoperatively in all age groups and at 6 months in participants aged 55-74 years; the 2ST score was significantly lower in participants aged between 65 and 74 years. CONCLUSIONS Women with DRF demonstrated lower grip strength and dynamic body balancing ability. Lower grip strength and dynamic body balancing ability were identified as significant risk factors in women with DRF, suggesting that these may be useful screening tools to assess fracture risk.

Abstract
UNLABELLED Our aim was to analyze trends in osteoporotic hip fracture rates in a suburban health area over a long time period. We detected a steady decrease, especially in women, that could be explained by historical, administrative, lifestyle changes as well as by medical behavior. PURPOSE The purpose of this study was to analyze trends in osteoporotic hip fracture rates in a suburban health area over a long time period. METHODS This is an ecological retrospective study of all discharges occurring in the Alcorcón health area and registered in the minimum basic data set (MBDS). The incidence of osteoporotic hip fracture was calculated by age and sex strata over the last 17 years. General lineal models were used to analyze trends. RESULTS Between 1999 and 2015, 4271 osteoporotic hip fractures occurred in people over 45 (78% women; mean age 83). The annual osteoporotic hip fracture rate was 290/100,000 persons over 45 (women 428; men 134), or 767/100,000 persons over 65 (women 1087, men 364). The incidence of fractures decreased yearly by 3.6% (95% CI 2.8 to 4.5) in the 1999-2015 period (p < 0.001) and was more pronounced in women [3.9% (95% CI 3.0 to 4.8)] than in men [2.4% (95% CI 0.9 to 3.8)]. In people over 65 years, fracture incidence decreased yearly by 3.7% (95% CI 2.8 to 4.6; p < 0.001). Again, this was more pronounced in women [4% (95% CI 3.05 to 4.9)] than in men [2.4 (95% CI 0.8 to 3.9)] while the female/male ratio decreased from 4.45 in 1999 to 2.4 in 2015. These differences were similar for extracapsular and intracapsular fractures. CONCLUSIONS These findings suggest a downward trend in the incidence of hip fracture in Alcorcón, both in men and in women. Possible explanations are discussed, including the effectiveness of osteoporosis diagnosis and treatment campaigns over the last 20 years, and the so-called "cohort effect."

Abstract
Aim. To precisely estimate the effect of age on the risk of fracture hospitalisation among the Western Australia population over the life course. Methods. This population-based cohort study used hospital data on fractures for the period January 1991 to January 2013 among Western Australians born between 1915 and 1990. Results. The average incidence rates (per 10,000 person-years) of fracture hospitalisation (95% confidence interval) were 50.12 (49.90, 50.35), 55.14 (54.82, 55.48), and 45.02 (44.71, 45.32) for both males and females, males only, and females only, respectively. The age-specific rate of fracture hospitalisation (in natural logarithm form) in adults (>18 years) was well predicted by age at its 1st, 2nd, and 3rd power in males with an adjusted R-squared of 0.98 and p < 0.001. For females, the trend was also well predicted by its 1st and 2nd powers (the 3rd power term of age was removed due to its p value > 0.8) with an adjusted R-squared of 0.99 and p < 0.001. Conclusions. Overall trends in age and gender specific risk of fracture among the Western Australian population were similar to estimates reported from previous studies. The trend in fracture hospitalisation risk over the life course can be almost fully explained by age.

Abstract
UNLABELLED We investigated the incidence of fragility fractures from 2010 to 2012 in Sakaiminato, Japan. The incidence rates of limb fractures in Sakaiminato were lower than in Caucasian populations but had increased relative to data obtained in Japan in the 1990s. Clinical vertebral fractures occurred at higher rates in Sakaiminato than in Caucasian populations. INTRODUCTION To elucidate the incidence and prognosis of fragility fractures in Sakaiminato, Japan. METHODS A survey of all hip, distal radius, proximal humerus, and clinical vertebral fractures was performed from 2010 to 2012 in patients aged 50 or older in Sakaiminato city, Tottori prefecture, Japan. The age- and gender-specific incidence rates (per 100,000 person-years) were calculated based on the population of Sakaiminato city each year. The incidence rates of hip, distal radius, and proximal humerus fractures were compared with previous reports. We conducted a follow-up study assessing patients within 1 year following their initial treatment at two Sakaiminato hospitals. RESULTS The age-adjusted incidence rates in population aged 50 years or older (per 100,000 person-years) of hip, distal radius, proximal humerus, and clinical vertebral fractures were, respectively, 217, 82, 26, and 412 in males and 567, 432, 96, and 1229 in females. Age-specific incidence rates of hip, distal radius, and proximal humerus fractures all increased since the 1990s. Our study also revealed that anti-osteoporotic pharmacotherapy was prescribed 1 year post-fracture at rates of 29, 20, 30, and 50 % for patients with hip, distal radius, proximal humerus, and clinical vertebral fractures, respectively. CONCLUSIONS The incidence rates of limb fractures in Sakaiminato were substantially lower than Caucasian populations in northern Europe but had increased relative to data obtained in Japan in the 1990s. Unlike upper and lower limb fractures, clinical vertebral fractures occurred at higher rates in our study population than in other Asian and North European countries.

Abstract
UNLABELLED In this survey, the proportion of patients with distal forearm fractures admitted to the Parma University Hospital during 2012 (13 %) was relatively low and generally lower than that reported in other studies. In our region, the main orthopedic approach remains conservative. PURPOSE The purpose of this study was to define the ratio between hospitalized and non-hospitalized fragility fractures of the distal forearm in our province (Parma, Northern Italy). METHODS All forearm fractures referred during 2012 to the emergency department of the Parma University Hospital (the main hospital in the province with a catchment area of approximately 345,000) were retrieved from the hospital database using both ICD-9-CM codes and text strings. The diagnosis of distal forearm fracture due to low-energy trauma and the need for hospitalization were individually confirmed by medical records and X-ray reports. The analysis was limited to subjects aged 40 years and over. RESULTS In both sexes combined, 66 subjects out of 505 were hospitalized (13.1 %; confidence interval (CI) 95 % 10.4-16.3 %), 47 immediately (8.1 %) and 25 (5 %) after a few days. The percentage of cases hospitalized was 12 % in women (CI 95 % 9.2-15.6 %) and 17 % in men (CI 95 % 11.1-25 %; p = 0.16). CONCLUSIONS The percentage of fragility distal forearm fractures hospitalized in our area is relatively low and generally lower than that reported in other studies.

Abstract
UNLABELLED Only few studies have been published hitherto on country-specific incidence of distal forearm fracture. In the prevailing study, incidences were estimated, and trend analyses were performed for the entire Austrian population aged ≥50á. Incidence decreased significantly in women, but not in men, over the past 12 years of observation. INTRODUCTION To estimate incidence of distal forearm fracture and assess incidence trends in the entire Austrian population aged ≥50á from 1989-2010 for inpatient fractures and from 1999 to 2010 for all fractures. METHODS The number of inpatient forearm fractures was obtained from the Austrian Hospital Discharge Register (AHDR) for the entire population aged ≥50á from 1989 to 2010. Total number of distal forearm fractures was modeled using patient-level data on 36,327 patients with distal forearm fractures. Crude and age-standardized incidence rates (cases per 100,000) were estimated in 5-year age intervals. To analyze the change in incidence over time, average annual changes expressed as incidence rate ratios (IRR) were calculated. RESULTS For all distal forearm fractures, age-standardized incidence in women in 1999 and 2009 were estimated at 709 (95 % CI 675-743) and 607 (578-637), respectively. The age-standardized incidences in men the same years were estimated at 171 (156-185) and 162 (151-174), respectively. IRR analyses showed a significant decrease in women (-1.1 %, p < 0.01) but not in men (-0.8 %, p > 0.05) over the last 12 years (1999-2010). CONCLUSION Incidence of distal forearm fracture in the entire Austrian population is comparable to hip fracture incidence which is known to be among the highest worldwide. However, trend analyses reveal a significant decrease for all distal forearm fractures in women, but not in men, over the last 12 years.

Abstract
AIMS To evaluate health-related quality of life (HRQoL) and functionality among older men and women who suffered a wrist fracture because of a fall and to identify postfracture consequences. METHODS Observational, prospective cohort study of patients recruited in the emergency departments (ED) of six public hospitals of the Basque Health Service and one of the Catalan Health Service. Two groups of adults aged 65 or older were recruited: 960 with wrist fractures because of falls (fracture cohort) and 119 without fall-related wrist fractures in the previous year (non-fracture cohort). We collected sociodemographical and clinical data; general and specific HRQoL data measured by the 12-Item Short Form Health Survey (SF-12) and a short version of the Disabilities of the Arm, Shoulder, and Hand instrument (QuickDASH); and data about basic (BADL) and instrumental (IADL) activities of daily living, measured by the Barthel Index and the Lawton and Brody Index (LBI). RESULTS Women with wrist fractures exhibited greater declines than men 6 months after the fall in all questionnaires except the LBI, and greater declines than those in the non-fracture cohort independent of gender. Patients aged 80 years and older presented with worse baseline scores in all the outcome measures and lost more HRQoL and functionality after wrist fractures. DISCUSSION Women and older individuals experienced the greatest reductions in HRQoL and functionality after a fall-related wrist facture, suggesting that they might merit special attention in clinical care and public health policy. CONCLUSIONS Specific prevention strategies may be needed to avoid or reduce the consequences of fall-related wrist fractures.

Abstract
Osteoporotic fractures are a major worldwide epidemic. Here, we review global variability, ethnic differences and secular changes in osteoporotic fractures. Worldwide, age-standardized incidence rates of hip fracture vary >200-fold in women and >140-fold in men when comparing the country in which incidence rates are the highest with that in which they are the lowest. Median age-standardized rates are highest in North America and Europe, followed by Asia, Middle East, Oceania, Latin America and Africa. Globally, rates of hip fracture are greater in women than in men, with an average ratio of ∼2:1. The incidence of radiographic vertebral fractures is much higher than that of hip fractures, whereas the incidence rates of clinical vertebral fractures mirror hip fracture rates in most countries. Methodological challenges of defining and ascertaining vertebral fractures limit the interpretation of these data. Secular declines in hip fracture rates have been reported in populations from North America, Europe and Oceania. These declines are especially notable in women, suggesting that reproductive factors might contribute to this reduction. By contrast, hip fracture rates are increasing in parts of Asia and Latin America. Global indicators of health, education and socioeconomic status are positively correlated with fracture rates suggesting that lifestyles in developed countries might contribute to hip fracture. Improvements in fracture assessment, in particular for nonhip fractures, and identification of factors that contribute to this variability might substantially influence our understanding of osteoporotic fracture aetiology and provide new avenues for prevention.

Abstract
Osteoporotic fractures are associated with excess mortality and decreased functional capacity and quality of life. Age-standardized incidence rates of fragility fractures, particularly of the hip and forearm, have been noted to be decreasing in the last decade across many countries with the notable exception of Asia. The causes for the observed changes in fracture risk have not been fully identified but are likely the result of multiple factors, including birth cohort and period effects, increasing obesity, and greater use of anti-osteoporosis medications. Changing rates of fragility fractures would be expected to have an important impact on the burden of osteoporosis.

Abstract
INTRODUCTION Wrist fractures are common in older adults and are expected to increase because of ageing populations worldwide. The introduction of plate and screw fixation has changed the management of this trauma in many patients. For policymaking it is essential to gain insight into trends in epidemiology and healthcare utilisation. The purpose of this study was to determine trends in incidence, hospitalisation and operative treatment of wrist fractures. METHODS A population-based study of patients aged 50 years and older using the Dutch National Injury Surveillance System and the National Hospital Discharge Registry. Data on emergency department visits, hospitalisations and operative treatment for wrist fractures within the period 1997-2009 were analysed. RESULTS In women, the age-standardised incidence rate of wrist fractures decreased from 497.2 per 100,000 persons (95% confidence interval, 472.3-522.1) in 1997 to 445.1 (422.8-467.4) in 2009 (P for trend < 0.001). In men, no significant trends were observed in the same time period. Hospitalisation rates increased from 30.1 (28.3-31.9) in 1997 to 78.9 (75.1-82.8) in 2009 in women (P < 0.001), and from 6.4 (6.0-6.8) to 18.4 (17.3-19.5) in men (P < 0.001). There was a strong increase in operative treatment of distal radius fractures, especially due to plate fixation techniques in all age groups. CONCLUSION Incidence rates of wrist fractures decreased in women and remained stable in men, but hospitalisation rates strongly increased due to a steep rise in operative treatments. The use of plate and screw fixation techniques for distal radius fractures increased in all age groups.

Abstract
UNLABELLED Despite advances in prevention, fall-related hospitalisation rates among older people are still increasing. Rates between 1998/1999 and 2008/2009 for non-facture-related injuries increased by 6.1% while fracture injuries declined by -0.4%. Varying trends in rates of different injury types makes it difficult to provide a definitive explanation for these changes. INTRODUCTION Despite advances in fall prevention research and practice, the rate of fall-related hospitalisations continues to increase. However, hip fracture rates appear to be declining. An examination of trends in types of injuries that contribute to the overall fall injury rate is required to establish which injuries are driving the falls admission rate. The aim of this paper is to examine trends in fall-related injury hospital admissions by injury type in New South Wales (NSW), Australia. METHODS A retrospective review of fall-related injury hospitalisations in NSW among individuals aged 65+ years, by injury type, was conducted from 1 July 1998 to 30 June 2009. Direct age-standardised admission rates were calculated. Negative binomial regression was used to examine the statistical significance of changes in trend over time of different hospitalised fall-related injuries. RESULTS The fall-related hospitalisation rate increased by 1.7% each year (p < 0.0001; 95% confidence interval (CI), 1.3-2.1%). However, the rate of fracture declined by -0.4% (p < 0.03; 95% CI, -0.8-0.0%); whereas, the non-fracture rate increased by 6.1% (p < 0.0001; 95% CI, 5.5-6.7%) annually. Rates for severe head injuries, rib and pelvic fracture increased while those for hip and forearm fracture declined. CONCLUSIONS It appears that while fall prevention efforts in NSW are not yet affecting the overall rate of injury hospitalisation, there has been a significant decline in the rates of some fractures. Opposing trends in the rates of other fracture admissions and a significant increase in the rate of non-fracture injuries associated with falls makes a definitive explanation for these changes difficult.

Abstract
When using hospital discharge data to shape sports injury prevention policy, it is important to correctly identify cases. The objectives of this study were to examine the ease with which snow-skiing and snowboarding injury cases could be identified from national hospital discharge data and to assess the suitability of the information obtained for shaping policy. Hospital discharges for 2000-2004 were linked to compensated claims and searched sequentially using coded and narrative information. One thousand three hundred seventy-six eligible cases were identified, with 717 classified as snowboarding and 659 as snow-skiing. For the most part, cases could not be identified and distinguished using simple searches of coded data; keyword searches of narratives played a key role in case identification but not in describing the mechanism of injury. Identification and characterisation of snow sport injury from in-patient discharge records is problematic due to inadequacies in the coding systems and/or their implementation. Narrative reporting could be improved.

Abstract
Osteoporosis constitutes a major public health problem through its association with age-related fractures, most notably those of the proximal femur. Substantial geographic variation has been noted in the incidence of hip fracture throughout the world, and estimates of recent incidence trends have varied widely. Studies in the published literature have reported an increase, plateau, and decrease in age-adjusted incidence rates for hip fracture among both men and women. Accurate characterisation of these temporal trends is important in predicting the health care burden attributable to hip fracture in future decades. We therefore conducted a review of studies worldwide, addressing secular trends in the incidence of hip and other fractures. Studies in western populations, whether in North America, Europe or Oceania, have generally reported increases in hip fracture incidence through the second half of the last century, but those continuing to follow trends over the last two decades have found that rates stabilise with age-adjusted decreases being observed in certain centres. In contrast, some studies suggest that the rate is rising in Asia. This synthesis of temporal trends in the published literature will provide an important resource for preventing fractures. Understanding the reasons for the recent declines in rates of hip fracture may help understand ways to reduce rates of hip fracture worldwide.

Abstract
SUMMARY Policy decisions about the allocation of current and future resources should be based on the most accurate predictions possible. A functional data analysis (FDA) approach improves the understanding of current trends and future incidence of injuries. FDA provides more valid and reliable long-term predictions than commonly used methods. INTRODUCTION Accurate information about predicted future injury rates is needed to inform public health investment decisions. It is critical that such predictions derived from the best available statistical models to minimise possible error in future injury incidence rates. METHODS FDA approach was developed to improve long-term predictions but is yet to be widely applied to injury epidemiology or other epidemiological research. Using the specific example of modelling age-specific annual incidence of fall-related severe head injuries of older people during 1970-2004 and predicting rates up to 2024 in Finland, this paper explains the principles behind FDA and demonstrates their superiority in terms of prediction accuracy over the more commonly reported ordinary least squares (OLS) approach. RESULTS Application of the FDA approach shows that the incidence of fall-related severe head injuries would increase by 2.3-2.6-fold by 2024 compared to 2004. The FDA predictions had 55% less prediction error than traditional OLS predictions when compared to actual data. CONCLUSIONS In summary, FDA provides more accurate predictions of long-term incidence trends than commonly used methods. The production of FDA prediction intervals for future injury incidence rates gives likely guidance as to the likely accuracy of these predictions.

Abstract
UNLABELLED Unipedal standing time was shorter and bone mineral density was lower in Japanese women aged 50 years and over with low-energy distal radius fractures resulting from falls than those in age-matched community-dwelling Japanese women without distal radius fractures. INTRODUCTION The aim of this study was to compare unipedal standing time and bone mineral density (BMD) of women >or=50 years of age with distal radius fractures with those of age-matched women without fractures. METHODS Fracture group was 54 Japanese women with low-energy distal radius fractures resulting from fall. Non-fracture group was 52 community-dwelling Japanese women without fractures. Unipedal standing time and BMD were measured. RESULTS There were no significant differences in age and body mass index between the two groups. The percentage of women with unipedal standing time <15 s was 44.4% in the fracture group and 13.5% in the non-fracture group, while the respective frequencies for >120 s were 20.4% and 50.0%. The T-score of BMD was significantly lower in the fracture than non-fracture group. Logistic regression analysis identified unipedal standing time <15 s and T-score <70% as significant factors associated with distal radius fractures. Notably, T-score <70% was significant in subjects <65 years, and unipedal standing time <15 s was significant in those >or=65 years. CONCLUSION Unipedal standing time was shorter and BMD was lower in women >or=50 years of age with distal radius fractures than those in age-matched women without fractures.

Abstract
Falls and their injury outcomes have count distributions that are highly skewed toward the right with clumping at zero, posing analytical challenges. Different modelling approaches have been used in the published literature to describe falls count distributions, often without consideration of the underlying statistical and modelling assumptions. This paper compares the use of modified Poisson and negative binomial (NB) models as alternatives to Poisson (P) regression, for the analysis of fall outcome counts. Four different count-based regression models (P, NB, zero-inflated Poisson (ZIP), zero-inflated negative binomial (ZINB)) were each individually fitted to four separate fall count datasets from Australia, New Zealand and United States. The finite mixtures of P and NB regression models were also compared to the standard NB model. Both analytical (F, Vuong and bootstrap tests) and graphical approaches were used to select and compare models. Simulation studies assessed the size and power of each model fit. This study confirms that falls count distributions are over-dispersed, but not dispersed due to excess zero counts or heterogeneous population. Accordingly, the P model generally provided the poorest fit to all datasets. The fit improved significantly with NB and both zero-inflated models. The fit was also improved with the NB model, compared to finite mixtures of both P and NB regression models. Although there was little difference in fit between NB and ZINB models, in the interests of parsimony it is recommended that future studies involving modelling of falls count data routinely use the NB models in preference to the P or ZINB or finite mixture distribution. The fact that these conclusions apply across four separate datasets from four different samples of older people participating in studies of different methodology, adds strength to this general guiding principle.

Abstract
In Australia, benefits for antifracture therapies have been available for patients with osteoporosis and a prior fracture. No benefits were available to those with no prior fracture. We aimed to define, in women with no prior fracture, age-related thresholds of bone mineral density (BMD) associated with fracture risk equivalent to that of women with prior fracture and osteoporosis. A case-control study of women (> or =50 yr) was conducted, including 291 fracture cases and 823 controls. BMD was measured at the proximal femur and posterior anterior (PA) spine. A fracture risk score (FRS) for the group with no prior fracture was calculated with discriminant analysis. The thresholds for equivalent fracture risk between those with no prior fracture and those with prior fracture were assessed using logistic regression. Increasing the FRS to +0.98 in women with no prior fracture resulted in equivalent odds of sustaining a fracture to those with prior fracture and osteoporosis. The corresponding T-score thresholds at the spine were -4.6 at 50 yr, -3.9 at 60 yr, -3.1 at 70 yr, and -2.4 at 80 yr. The femoral neck T-score thresholds were lower by 0.5 standard deviation. The high-risk individuals defined by this study should be considered for primary fracture prevention therapy.

Abstract
Background A fracture of the distal radius is a commonly occurring fracture and accounts for a third of all fractures in the elderly. Thus far, one year estimates of pain and disability following a fracture of the distal radius have been reported on Canadian populations. The primary aim of this study is to investigate the prevalence of pain and disability in a UK population one year post fracture of the distal radius. Methods A cross-sectional survey was undertaken, of all subjects suffering a fracture of the distal radius between October 2005 and February 2006 in Nottingham, UK. Primary outcomes used were the VAS for pain and the DASH for disability. Prevalence of pain and disability were calculated and odds ratios presented for associations between demographics, pain and disability. Results 93/264 (35%) subjects responded to the questionnaire. 6 subjects did not fulfill the inclusion criteria and were excluded from further analysis. 11% of subjects reported moderate to very severe pain. 16% of subjects reported moderate to very severe disability. Statistically significant associations were found between pain medication usage for the wrist fracture and moderate to very severe pain (OR 11.20, 95% CI 2.05 – 61.23). Moderate to very severe disability was associated with older age (OR 6.53, 95%CI 1.65 – 25.90) and pain medication usage for the wrist fracture (OR 4.75, 95% CI 1.38 – 16.37). Working was associated with a reduction in risk of moderate to very severe disability (OR 0.14, 95% CI 0.03 – 0.67). Conclusion This study demonstrates that there are a small proportion of patients who are still suffering moderate to very severe pain and disability one year post fracture of the distal radius. The study also demonstrates that there are significant associations between characteristics of the patients and the level of pain and disability. This highlights the need for further research into the most appropriate management of these patients in order to reduce this burden of pain and disability, particularly as this is a predominantly elderly patient group.

Abstract
The aim of this paper is to estimate the proportion of older people who are hospitalised following a presentation to an emergency department for hip, pelvic and wrist fractures. The findings indicate that hospitalisation data do not accurately reflect the incidence of low-trauma fractures, particularly wrist and pelvic fractures, in older people.
