  • Mortality following benign sacral insufficiency fracture and associated
           risk factors
    • Authors: Jae-Woo Park; Sang-Min Park; Hui Jong Lee; Choon-Ki Lee; Bong-Soon Chang; Hyoungmin Kim
      Abstract: Summary This study demonstrated increased mortality following sacral insufficiency fractures as with other major osteoporotic fractures. The 6-month mortality rate was 9.8%, the 1-year mortality rate was 17.5%, and the 3-year mortality rate was 25.5%. Sex- and age-adjusted standardized mortality ratio increased after fractures. Introduction There are no data about mortality after sacral insufficiency fractures. The purposes of this study were to investigate the mortality rate among sacral insufficiency fracture patients and to identify risk factors associated with mortality. Methods This is a retrospective cohort study of patients diagnosed with sacral insufficiency fracture via radiological exam in a single institute from 2001 to 2014, excluding patients with pathological sacral fracture due to metastasis or primary tumor. Mortality and its predisposing factors were analyzed based on a review of electronic medical records and mortality data provided by the Korean Statistical Information Service. Kaplan–Meier survival analysis and Cox regression analysis were used for statistical analysis. Results A total of 325 patients were included (275 women and 50 men). The mean age at the time of diagnosis was 69.4 years. One hundred and forty patients (43.1%) had a history of malignancy, and 71 patients (21.8%) had undergone pelvic radiation therapy before fracture diagnosis. Twenty-one patients (6.5%) underwent sacroplasty, and the others underwent conservative management after fracture diagnosis. The mean follow-up was 51.5 months, and a total of 101 patients died at the final follow-up. The 6-month mortality rate was 9.8%, the 1-year mortality rate was 17.5%, and the 3-year mortality rate was 25.5%. Sex- and age-adjusted standardized mortality ratio (SMR) increased after fractures. The overall SMR is 8.9 at 3 months decreasing to 4.5 at 2 years. Multivariable Cox regression analysis showed that significant factors associated with increased mortality were male gender, malignancy history, lumbosacral fusion with distal fusion level S1, stroke history, low total femur bone mineral density score, and low body mass index. Conclusions Like other types of osteoporotic fractures, sacral insufficiency fractures are associated with increased mortality.

      Abstract: Summary Fracture probabilities derived from the surrogate FRAX model for Armenia were compared to those from the model based on regional estimates of the incidence of hip fracture. Disparities between the surrogate and authentic FRAX models indicate the importance of developing country-specific FRAX models. Despite large differences between models, differences in the rank order of fracture probabilities were minimal. Objective Armenia has relied on a surrogate FRAX model based on the fracture epidemiology of Romania. This paper describes the epidemiology of fragility fractures in Armenia used to create an Armenia-specific FRAX model with an aim of comparing this new model with the surrogate model. Methods We carried out a population-based study in two regions of Armenia (Ararat and Vayots Dzor representing approximately 11% of the country’s population). We aimed to identify all low-energy fractures: retrospectively from hospital registers in 2011–2012 and prospectively in 2013 with the inclusion of primary care sources. Results The differences in incidence between the surveys with and without data from primary care suggested that 44% of patients sustaining a hip fracture did not receive specialized medical care. A similar proportion of forearm and humeral fractures did not come to hospital attention (48 and 49%, respectively). Only 57.7% of patients sustaining a hip fracture were hospitalized. In 2013, hip fracture incidence at the age of 50 years or more was 201/100,000 for women and 136/100,000 for men, and age- and sex-specific rates were incorporated into the new “authentic” FRAX model for Armenia. Compared to the surrogate model, the authentic model gave lower 10-year fracture probabilities in men and women aged less than 70 years but substantially higher above this age. Notwithstanding, there were very close correlations in fracture probabilities between the surrogate and authentic models (> 0.99) so that the revisions had little impact on the rank order of risk. Conclusion A substantial proportion of major osteoporotic fractures in Armenia do not come to hospital attention. The disparities between surrogate and authentic FRAX models indicate the importance of developing country-specific FRAX models. Despite large differences between models, differences in the rank order of fracture probabilities were minimal.

      Abstract: Summary Compared to urban residents, those in rural/regional areas often experience inequitable healthcare from specialist service providers. Independent of small between-area differences in utilisation, socially advantaged groups had the greatest uptake of joint replacement. These data suggest low correlation between ‘need’ vs. ‘uptake’ of surgery in rural/regional areas. Background and purpose Compared to urban residents, those in rural and regional areas often experience inequitable healthcare from specialist service providers, often due to geographical issues. We investigated associations between socioeconomic position (SEP), region of residence and utilisation of primary total knee replacement (TKR) and/or total hip replacement (THR) for osteoarthritis. Design and methods As part of the Ageing, Chronic Disease and Injury study, we extracted data from the Australian Orthopaedic Association National Joint Replacement Registry (2011–2013) for adults that utilised primary TKR (n = 4179; 56% female) and/or THR (n = 3120; 54% female). Residential addresses were matched with the Australian Bureau of Statistics (ABS) 2011 census data: region of residence was defined according to local government areas (LGAs), and area-level SEP (quintiles) defined using an ABS-derived composite index. The ABS-determined control population (n = 591,265; 51% female) excluded individuals identified as cases. We performed multilevel logistic regression modelling using a stratified two-stage cluster design. Results TKR was higher for those aged 70–79 years (AOR 1.4 95%CI 1.3–1.5; referent = 60–69 years) and in the most advantaged SEP quintile (AOR 2.1, 95%CI 1.8–2.3; referent = SEP quintile 3); results were similar for THR (70–79 years = AOR 1.7, 95%CI 1.5–1.8; SEP quintile 5 = AOR 2.5, 95%CI 2.2–2.8). Total variances contributed by the variance in LGAs were 2% (SD random effects ± 0.28) and 3% (SD ± 0.32), respectively. Conclusion Independent of small between-LGA differences in utilisation, and in contrast to the expected greater prevalence of osteoarthritis in disadvantaged populations, we report greater TKR and THR in more advantaged groups. Further research should investigate whether more advantaged populations may be over-serviced.

  • Implementation of a fall screening program in a high risk of fracture
    • Authors: Katherine Ritchey; Amanda Olney; Jane Shofer; Elizabeth A. Phelan; Alvin M. Matsumoto
      Abstract: Summary Fall prevention is an important way to prevent fractures in person with osteoporosis. We developed and implemented a fall screening program in the context of routine osteoporosis care. This program was found to be feasible and showed that a significant proportion of persons with osteoporosis are at risk of falling. Purpose Falls are the most common cause of fracture in persons with osteoporosis. However, osteoporosis care rarely includes assessment and prevention of falling. We thus sought to assess the feasibility of a fall screening and management program integrated into routine osteoporosis care. Methods The program was developed and offered to patients with osteoporosis or osteopenia seen at an outpatient clinic between May 2015 and May 2016. Feasibility was measured by physical therapist time required to conduct screening and ease of integrating the screening program into the usual clinic workflow. Self-report responses and mobility testing were conducted to describe the fall and fracture risk profile of osteoporosis patients screened. Effects on fall-related care processes were assessed via chart abstraction of patient participation in fall prevention exercise. Results Of the 154 clinic patients who presented for a clinic visit, 68% met screening criteria and completed in two thirds of persons. Screening was completed in a third of the time typically allotted for traditional PT evaluations and did not interfere with clinic workflow. Forty percent of those screened reported falling in the last year, and over half had two or more falls in the past year. Over half reported a balance or lower extremity impairment, and over 40% were below norms on one or more performance tests. Most patients who selected a group exercise fall prevention program completed all sessions while only a quarter completed either supervised or independent home-based programs. Conclusions Implementation of a fall risk screening program in an outpatient osteoporosis clinic appears feasible. A substantial proportion of people with osteoporosis screened positive for being at risk of falling, justifying integration of fall prevention into routine osteoporosis care.

  • Metabolically healthy/unhealthy components may modify bone mineral density
           in obese people
    • Authors: Atieh Mirzababaei; Khadijeh Mirzaei; Leila Khorrami-nezhad; Zhila Maghbooli; Seyed Ali Keshavarz
      Abstract: Summary Link between obesity and bone health is controversial. It seems that maybe the difference in metabolic status leads to this difference. We studied relation between metabolically healthy/unhealthy components with bone mineral density. Results showed metabolically unhealthy obesity (MUHO) phenotypes have better bone status at hip site than metabolically healthy obesity (MHO). Also, component metabolic can effect on BMD in different sites. Purpose/Introduction This cross-sectional study aimed to compare total BMD and L-L4 BMD in MHO and MUHO base on Karelis criteria. Methods We enrolled 272 Iranian obese women and men (BMI ≥ 30). According to Karelis criteria, the participants were grouped base to MHO and MUHO. The body composition and BMD were assessed for all cases. Serum HDL-C, LDL-C, total cholesterol, triglyceride (TG), fasting blood glucose, homeostatic model assessment-insulin resistance (HOMA-IR), and hypersensitive C-reactive protein (hs-CRP) levels were quantified by ELISA method. Results Our results demonstrate MUHO phenotype have high total BMD more than MHO (P = 0.01, CI = 0.12 to 0.21). Also, the results of logistic regression analysis showed MUHO have strongly associated with total BMD (β = −0.42, CI = − 0.31 to − 0.04, P = 0.009), but did not affected L2-L4 BMD (β = − 0.09, CI = − 0.14 to 0.08, P = 0.578); this represents that there was discordance in MUHO subjects. Our evidence implicated that HOMA-IR, high level serum TG, hs-CRP, and low level serum HDL had mediatory effect on relationship between obesity and high BMD at the hip region in MUHO subjects (P < 0.05). Conclusion Present evidence indicates that, could be a novel link between difference in MUH phenotype and MH phenotype with bone status. Also, component metabolic can effect on BMD in different sites.

  • Long-term use of angiotensin-converting enzyme inhibitors protects against
           bone loss in African-American elderly men
    • Authors: Nahid Rianon; Catherine G. Ambrose; Hannah Pervin; Melissa Garcia; Scherezade K. Mama; Ann V. Schwartz; Brendan Lee; Tamara Harris
      Abstract: Summary Greater bone mineral density was observed after treating hypertension using angiotensin-converting enzyme inhibitor (ACEi). We report decreased rate of bone loss in hypertensive black men using ACEi for 9 years. There may be a gender- and race-specific effect of ACEi in the prevention of age-associated bone loss. Purpose There is evidence of bone mass preservation in patients receiving ACEis, commonly used to treat hypertension. However, limitations of previous studies include being cross-sectional or only including a short-term follow-up of patients using ACEi and including patients with diabetes, which affects bone metabolism. None of the previous studies described effects of ACEi stratified by race. The objective of this study was to investigate differences in changes in bone mineral density (BMD) in older adults who suffer from hypertension and had reported ACEi use during each study visit for at least 9 years during the study, stratified by gender and race. Methods We used data from the Dynamics of Health, Aging and Body Composition (HABC) study, which enrolled 3075 community-dwelling older white and black individuals. We compared changes in femoral neck, total hip, and whole-body BMD after either no use of ACEi (n = 580) or long-term use (at least 9 years) of ACEi (n = 239) in HABC participants with hypertension and no known diagnosis of diabetes mellitus. Results Overall, BMD values significantly decreased for all subgroups over time. In the stratified multivariate analysis, long-term use of ACEi was associated with a reduced rate of decline for all three BMD measures among black men, but no significant effect was observed in the other subgroups. Conclusion Our findings show a gender- and race-specific effect of ACEi in the prevention of age-associated bone loss that warrants further evaluation.

      Abstract: Summary We evaluated the state of osteopenia and the physical function in 121 schizophrenic patients. These factors were worse in the inpatient group than in the outpatient group. The age, sex, body mass index (BMI), and physical function were correlated to the state of osteopenia. Physicians should consider the risk of osteopenia in elderly female psychiatric patients with low BMI. Purpose Information about the actual state of osteopenia in patients with schizophrenia is limited. In the present study, we evaluated the factors related to osteopenia and patient’s physical function and compared these factors between inpatients and outpatients. Methods A total of 121 schizophrenic patients were included in the present study. We divided the patients into two groups according to the therapeutic form. We collected data on their age, sex, body mass index (BMI), bone mineral density (BMD) in the lumbar spine and proximal femur, serum bone metabolic markers, risk of fracture, and physical function. Results The number of fractured vertebrae, risk of fracture, serum concentration of tartrate-resistant acid phosphatase 5b (TRACP-5b), and score of locomo25 were significantly higher and the BMI and BMD in the lumbar spine and proximal femur significantly lower in the inpatient group than in the outpatient group. A multiple regression analysis showed that the age, sex, BMI, the number of fractured vertebrae, and score of locomo 25 were correlated with the BMD in the lumbar spine and proximal femur. Neither the therapeutic form nor any bone metabolic markers were correlated with the BMD. The inpatient group had a lower average BMI, BMD, and physical function than the outpatient group. However, a multiple regression analysis showed that the therapeutic form was not correlated with the BMD. Conclusion These findings suggest that physicians should consider elderly female schizophrenic patients with a low BMI to be at risk of developing osteopenia.

      Abstract: Summary This nationwide study investigated the epidemiology, treatment patterns, and economic burden of osteoporosis and associated fracture in Taiwan. The treatment of osteoporosis is alarmingly suboptimal, considering the significantly increased economic burden of major osteoporotic fracture. Osteoporosis men received lesser anti-osteoporosis drugs but had higher incremental costs attributable to osteoporotic fractures. Purpose This nationwide study investigated the epidemiology, treatment patterns, and economic burden of osteoporosis and associated fracture between 2009 and 2013 in Taiwan. Methods We used the National Health Insurance Research Database as our data source. The prevalence of diagnosed osteoporosis and major osteoporotic fractures was calculated annually from 2009 to 2013, stratified by age and gender. Osteoporosis patients who received any prescription of anti-osteoporosis drugs during each fiscal year were defined as osteoporosis patients under treatment. Healthcare utilization and associated direct medical costs were used to quantify the economic burden of osteoporosis. For patients who encountered major osteoporotic fracture, the incremental changes of direct medical costs attributable to fracture using a pre- and post-quasi-experimental design were estimated. Furthermore, we compared the annual direct medical costs of patients who encountered major osteoporotic fracture with those diagnosed osteoporosis only and with the general population. Results The prevalence of diagnosed osteoporosis increased with age, with the highest rate among those aged 80 and older. Overall, less than one-third of women and only 10% of men received anti-osteoporosis drugs among osteoporosis patients. The annual direct medical costs for osteoporosis patients increased steadily from 2009 to 2013. The total medical costs and incremental change of direct medical costs were higher in men than those in women. Conclusion We found the treatment of osteoporosis to be alarmingly suboptimal, considering the significantly increased economic burden of major osteoporotic fracture also identified in this study. Osteoporosis men received lesser anti-osteoporosis drugs but had higher incremental costs attributable to major osteoporotic fractures.

      Abstract: Summary Femoral neck bone mineral density (BMD), age plus femoral neck BMD T score, and three externally generated fracture risk tools had similar accuracy to identify older men who developed osteoporotic fractures. Risk tools with femoral neck BMD performed better than those without BMD. The externally developed risk tools were poorly calibrated. Introduction We compared the performance of fracture risk assessment tools in older men, accounting for competing risks including mortality. Methods A comparative ROC curve analysis assessed the ability of the QFracture, FRAX® and Garvan fracture risk tools, and femoral neck bone mineral density (BMD) T score with or without age to identify incident fracture in community-dwelling men aged 65 years or older (N = 4994) without hip or clinical vertebral fracture or antifracture treatment at baseline. Results Among risk tools calculated with BMD, the discriminative ability to identify men with incident hip fracture was similar for FRAX (AUC 0.77, 95% CI 0.73, 0.81), the Garvan tool (AUC 0.78, 95% CI 0.74, 0.82), age plus femoral neck BMD T score (AUC 0.79, 95% CI 0.75, 0.83), and femoral neck BMD T score alone (AUC 0.76, 95% CI 0.72, 0.81). Among risk tools calculated without BMD, the discriminative ability to identify hip fracture was similar for QFracture (AUC 0.69, 95% CI 0.66, 0.73), FRAX (AUC 0.70, 95% CI 0.66, 0.73), and the Garvan tool (AUC 0.71, 95% CI 0.67, 0.74). Correlated ROC curve analyses revealed better diagnostic accuracy for risk scores calculated with BMD compared with QFracture (P < 0.0001). Calibration was good for the internally generated BMD T score predictor with or without age and poor for the externally developed risk tools. Conclusion In untreated older men without fragility fractures at baseline, an age plus femoral neck BMD T score classifier identified men with incident hip fracture as accurately as more complicated fracture risk scores.

  • A focused evaluation of lumbar spine trabecular bone score in the first
           year post-menarche
    • Authors: Jodi N. Dowthwaite; R. Winzenrieth; N. Binkley; D. Krueger; T. A. Scerpella
      Abstract: Summary Trabecular bone score, an index of lumbar spine trabecular texture, has not been explored fully in adolescent girls. Our cross-sectional analysis supported the hypothesis that “adult normal” trabecular bone score has been achieved by the end of the first year post-menarche, providing a potential screening tool, independent from bone density. Introduction Trabecular bone score (TBS) evaluates lumbar spine (LS) trabecular texture from DXA images. Limited evidence suggests low TBS in pre-pubertal girls. TBS has not been assessed in the context of the key peri-menarcheal bone accrual phase. Thus, we evaluated (1) whether “normal” adult TBS (≥ 1.35) is reached in the first year post-menarche and (2) the role of maturational timing (menarcheal age) and status (gynecological age) in TBS variation. Methods For 44 healthy girls aged 11 to 13 years, whole body and LS DXA scans were obtained within 1 year post-menarche. As TBS is optimized for adults and can be affected by body thickness, custom software provided unadjusted “rawTBS” and adjusted for tissue thickness “corrTBS” (TBS iNsight, Medimaps, France). Correlations evaluated menarcheal age and gynecological age as factors in LS bone mineral content (BMC), areal bone mineral density (BMD), and TBS. Results Lowest observed TBS exceeded 1.35 (rawTBS = 1.362; corrTBS = 1.352). Menarcheal age correlated negatively with rawTBS (r = − 0.34, p = 0.02), with a similar trend for corrTBS (r = − 0.29, p < 0.06). Gynecological age did not correlate with TBS but was positively correlated with LSBMD (r = + 0.37, p = 0.01). Correlations with body composition variables differed between rawTBS and corrTBS. Conclusions In this healthy cohort, “normal” adult TBS is present by 1 year post-menarche, 2 years before projected LS peak bone mass. Thus, TBS may be a useful bone architectural screen during the first post-menarcheal year, enabling intervention to improve structure prior to “peak bone mass”. Longitudinal studies are needed to elucidate TBS development and intervention response.

  • Vertebral heights and ratios are not only race-specific, but also gender-
           and region-specific: establishment of reference values for mainland
    • Authors: Lei Ning; Li-Jiang Song; Shun-Wu Fan; Xing Zhao; Yi-lei Chen; Zhao-Zhi Li; Zi-Ang Hu
      Abstract: Summary This study established gender-specific reference values in mainland Chinese (MC) and is important for quantitative morphometry for diagnosis and epidemiological study of osteoporotic vertebral compressive fracture. Comparisons of reference values among different racial populations are then performed to demonstrate the MC-specific characteristic. Purpose Osteoporotic vertebral compressive fracture (OVCF) is a common complication of osteoporosis in the elder population. Clinical diagnosis and epidemiological study of OVCF often employ quantitative morphometry, which relies heavily on the comparison of patients’ vertebral parameters to existing reference values derived from the normal population. Thus, reference values are crucial in clinical diagnosis. To our knowledge, this is the first study to establish reference values of the mainland Chinese (MC) for quantitative morphometry. Methods Vertebral heights including anterior (Ha), middle (Hm), posterior (Hp) heights, and predicted posterior height (pp) from T4 to L5 were obtained; and ratios of Ha/Hp, Hm/Hp and Hp/pp. were calculated from 585 MC (both female and male) for establishing reference values and subsequent comparisons with other studies. Results Vertebral heights increased progressively from T4 to L3 but then decreased in L4 and L5. Both genders showed similar ratios of vertebral dimensions, but male vertebrae were statistically larger than those of female (P < 0.01). Vertebral size of MC population was smaller than that of US and UK population, but was surprisingly larger than that of Hong Kong Chinese, although these two are commonly considered as one race. Data from different racial populations showed similar dimensional ratios in all vertebrae. Conclusions We established gender-specific reference values for MC. Our results also indicated the necessity of establishing reference values that are not only race- and gender-specific, but also population- or region-specific for accurate quantitative morphometric assessment of OVCF.

    • Authors: Riad A. Sulimani; Ashry G. Mohammed; Suliman N. Alshehri; Assim A. Alfadda; Abdulaziz Al-Othman; Aliya A. Khan
      Abstract: Summary This study examined the effects of weekly 35,000 IU vitamin D supplementation for 4 weeks on bone turnover markers (BTMs). There was improvement in the levels of parathyroid hormone (PTH), osteocalcin, and carboxy-terminal telopeptides of crosslinks of type 1 collagen (βCTX) which paralleled the increase in vitamin D levels. Purpose The effects of vitamin D supplementation on bone turnover markers (BTMs) have been inconsistent. This study examined the effects of weekly 35,000 IU vitamin D supplementation for 1 month on BTMs. Methods Sixty-eight vitamin D deficient adolescent females were given 35,000 IU of vitamin D3 for 4 weeks. Pre and post intervention blood samples were taken for 25(OH) D, PTH, osteocalcin and βCTX. Results There was a significant increase in serum 25 (OH) D in the post intervention period which was accompanied by a significant decrease in PTH, osteocalcin and βCTX (P < 0.001). Conclusions We concluded that weekly 35,000 IU vitamin D supplementation for 4 weeks results in significant improvement of BTMs.

  • Minimal-trauma ankle fractures predominate during pregnancy: a 17-year
           retrospective study
    • Authors: Madhuni Herath; Phillip Wong; Anne Trinh; Carolyn A. Allan; Euan M. Wallace; Peter R. Ebeling; Peter J. Fuller; Frances Milat
      Abstract: Summary This study assessed all fractures occurring in pregnancy at a tertiary referral centre over a 17-year period. Most fractures were due to minimal trauma, and those involving the ankle were the most common. Women tended to fracture during their second and third trimesters and most required surgical intervention during pregnancy. Purpose To characterise fractures in pregnancy over a 17-year period at a tertiary referral health service. Methods Medical records at the Monash Health in Australia were examined from 2000–2016 for fractures in pregnancy using the birthing outcome system database and the tenth revision of the International Statistical Classification of Diseases and Related Health Problems coding. Site, mechanism, investigations, management and outcomes were documented. Results Of the 114,673 live births during this period, 33 women (mean age 30.3 ± 1.9 years) were identified with fracture in pregnancy (~ 2.9 maternal fractures/10,000 live births). Minimal-trauma fractures (MTFs) occurred in 28 women whilst 5 were due to motor vehicle accidents. Of the MTF, 2/28 (7.1%), 13/28 (46.4%) and 13/28 (46.4%) occurred in the first, second and third trimesters, respectively. MTF involved the lower limb (60.7%), upper limb (25.0%), ribs (10.7%) and clavicle (3.6%). The ankle was involved in 39.3% of MTFs. Diabetes (14.3%), asthma (10.7%) and thyroid dysfunction (7.1%) affected these women with MTF; vitamin D levels were not routinely measured. Surgical interventions requiring anaesthesia were required in 57.1% with MTF: 50.0% during their second, 31.3% in their third and 12.5% in their first trimesters; 6.3% had surgery post partum. Pre-term birth and emergency caesarean section complicated 6/28 (21.4%) of MTF pregnancies. One patient received post-partum bisphosphonate therapy; only two 2/32 (6.25%) received medical follow-up. Conclusions Fractures in pregnancy are uncommon. Lower limb fractures are frequently due to minimal trauma, and surgical intervention is often required. The low rate of medical follow-up in MTF is of concern and reinforces the need for greater recognition of potential osteoporosis in this population.

    • Authors: Kristen B. Pitzul; Walter P. Wodchis; Hans J. Kreder; Michael W. Carter; Susan B. Jaglal
      Abstract: Summary This study determines outcomes and costs of similar hip fracture patients that were discharged from hospital to a rehabilitation facility or to the community within 1 year. Community patients had worse outcomes and lower costs compared to rehabilitation facility patients. This study contributes to understanding hip fracture quality of care. Purpose The purpose of this study is to determine the impact on mortality and rehospitalization, as well as health system cost, of similar hip fracture patients being discharged to an inpatient rehabilitation facility or directly to the community within 1 year in Ontario, Canada. Methods This was a retrospective study of a propensity-matched cohort completed from the health system perspective. Administrative databases were used to identify and match two groups of older adults (total n = 18,773) discharged alive from acute care for hip fracture repair: patients discharged to inpatient rehabilitation were matched to patients discharged to the community. Results A higher proportion of patients discharged to the community (27–42%) died or were rehospitalized (SDhighipr = 0.21, SDlowipr = 0.33) and had substantially lower health system costs (SDhighipr = 0.65, SDlowipr = 0.42) up to 1 year post-acute discharge compared to similar patients discharged to inpatient rehabilitation facilities (IPR) (10–11%). Conclusions This study demonstrates that similar hip fracture patients are discharged to different post-acute settings (i.e., home-based rehabilitation and inpatient rehabilitation) and have different outcomes, thereby calling into question the appropriateness of post-acute rehabilitation delivery in Ontario, Canada. Future research should focus on determining how trade-offs in resource allocation between settings would impact patient outcomes.

      Abstract: Summary 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: Summary The association between vitamin D and muscle function associated with balance recovery and falls in people with knee osteoarthritis is unclear. Those with vitamin D insufficiency demonstrated poorer knee function during balance recovery, greater pain and locomotor dysfunction. Vitamin D insufficiency may have an adverse effect on muscle power function. Purpose Low vitamin D status in people with knee osteoarthritis (OA) is often reported to be associated with increased pain and locomotor dysfunction. However, despite the growing evidence of the effect of vitamin D on the pathogenesis of knee OA, its role remains conflicting. Importantly, muscle function is important for knee joint health; however, the association between vitamin D levels and muscle function associated with balance recovery and falls is unclear. This study investigated the effect of circulating 25-hydroxyvitamin D (25 (OH) D) on pain, quadriceps strength, lower limb muscle mass and knee power function during balance recovery in people with knee OA. Methods Twenty-four participants with clinical symptoms of knee OA (68.6 ± 6.2 years) participated in the study. Serum levels of 25 (OH) D were assessed and participants were classified as follows: vitamin D insufficiency ≤ 50 nmol/L and vitamin D sufficiency > 50 nmol/L. The groups were compared on knee function during balance recovery tasks, lower limb strength and muscle mass as well as perceived pain and function. Results Seven patients (29.1%) were classified as vitamin D-insufficient. Vitamin D insufficiency was associated with reduced knee muscle function during the balance recovery task, increased pain (Western Ontario and McMasters University Osteoarthritis Index (WOMAC) subscore), dysfunction (WOMAC subscore) and total WOMAC score (p < 0.05). Conclusion People with knee OA with vitamin D insufficiency demonstrated poorer knee function during balance recovery, greater pain and locomotor dysfunction. Vitamin D insufficiency may have an adverse effect on muscle power function.
