Physical function trajectory after wrist or lower arm fracture in postmenopausal women: results from the Women's Health Initiative Study.

Long-term physical functioning trajectories following distal forearm fracture are unknown. We found that women with versus those without distal forearm fracture were more likely to experience a 5-year decline in physical functioning, independent of initial physical functioning level. This association was most evident among women 80 years and older. INTRODUCTION: Physical functioning trajectory following lower arm or wrist fracture is not well understood. PURPOSE: This study is to evaluate physical functioning trajectory before vs. after lower arm or wrist fracture, stratified by age. METHODS: We performed a nested case-control study of prospective data from the Women's Health Initiative Study (n = 2097 cases with lower arm or wrist fracture, 20,970 controls). Self-reported fractures and the physical functioning subscale of the RAND 36-item Short-Form Health Survey were assessed annually. We examined three physical functioning trajectory groups: stable, improving, and declining. RESULTS: Mean (SD) number of physical functioning measurements was 5.2 (1.5) for cases and 5.0 (1.4) for controls. Declining physical functioning was observed among 20.4% of cases and 16.0% of controls. Compared to women without lower arm or wrist fracture, women with lower arm or wrist fracture were 33% more likely to experience declining physical functioning (adjusted odds ratio [aOR] 1.33 95% confidence interval [CI] 1.19-1.49, reference group stable or improving physical functioning trajectory). Associations varied by age: age ≥ 80 years aOR 1.56 (95% CI 1.29-1.88); age 70-79 years aOR 1.29 (95% CI 1.09-1.52); age < 70 years aOR 1.15 (95% CI 0.86-1.53) (pinteraction = 0.06). Associations between lower arm or wrist fracture and odds of declining physical functioning did not vary by baseline physical functioning or physical activity level. CONCLUSIONS: Women with lower arm or wrist fracture, particularly those aged 80 and older, were more likely to experience declines in physical functioning than women without such fractures, independent of baseline physical functioning level.

Rehabilitation of Patients With Osteoporotic Fractures.

Osteoporosis is a silent, asymptomatic disease until a fragility fracture is sustained. Fractures greatly affect the physical functioning and health-related quality of life and are associated with increased mortality and morbidity rates. Furthermore, once a fragility fracture occurs, the patient is more susceptible to sustain further fractures. Repeated falls are the main causes of fractures in patients with osteoporosis. The management of osteoporosis postfracture is a combination of medical treatment, nutritional interventions, and rehabilitation in order to improve activities of daily living to prevent falls and increase safety while reducing the loss of bone mass. In this article the principles of fracture prevention and physical rehabilitation of patients with osteoporosis postvertebral and hip fragility fractures will be discussed, as well as the rehabilitation management to prevent further falls and fractures.

Unknown osteoporosis in older patients admitted to post-acute rehabilitation.

BACKGROUND: Osteoporotic fractures are associated with increased morbidity, mortality, and increased health care use. As the number of older adults increases, identifying those at increased risk for osteoporotic fractures has become of utmost importance to providing them with preventive and therapeutic interventions. AIMS: To determine the prevalence of unknown clinical and densitometric osteoporosis and to investigate the performance of different diagnostic strategies for osteoporosis in elderly patients admitted to rehabilitation. METHOD: This is an observational study. Eligible participants were older adults admitted to rehabilitation in an academic hospital in Switzerland over an 11-month period. Patients with previously unknown osteoporosis underwent dual-energy X-ray absorptiometry (DXA), vertebral fracture assessment (VFA), and history review for past fractures. RESULTS: Complete assessment was available for 252 patients. Previously undiagnosed osteoporosis was identified in 62.3% of these patients, a proportion that was higher among women (71.5%) than men (44.8%). DXA proved most sensitive, followed by VFA and history review. Results differed across gender: DXA remained the most sensitive single test among women, but VFA proved most sensitive in men. The best test to combine with history review was DXA in women (detection increasing from 47.5 to 93.2%) and VFA in men (detection increasing from 35.9 to 84.6%). CONCLUSIONS: Prevalence of previously unknown osteoporosis appears very high in elderly patients admitted to post-acute rehabilitation. The combination of history review of previous fractures with DXA in women and with VFA in men appears the best two-step strategy to improving detection of osteoporosis in this population.

Risk of institutionalization following fragility fractures in older people.

Previously independent living older people suffering fractures of the hip have a high risk of new admission to a nursing home during the subsequent months. This study shows that older people admitted to hospital for fractures of the pelvis and spine have a similar risk of admission to a nursing home. INTRODUCTION: Fall-related fractures are a serious threat to the health and well-being of older persons. Long-term consequences of hip fractures such as institutionalization and mortality are well-known. The impact of other fragility fractures is less well-understood. The aim of this study was to estimate risks of institutionalization and death for different fragility fractures and compare them with the corresponding risks after hip fracture. METHODS: Data was retrieved from a German health insurance company. Between 2005 and 2008 more than 56,000 community-dwelling people with a hospital admission or discharge diagnosis of a fracture of the femur, spine, pelvis, proximal humerus, distal radius, tibia, or fibula were included. Crude and age-adjusted 6-month incidence rates for institutionalization and death were calculated. To compare the risks of institutionalization or mortality of non-hip fractures with the risk after hip fracture, multivariate regression models were applied. RESULTS: Crude institutionalization rates and mortality were highest in patients with hip fracture. However, after adjustment for age, functional status, and comorbidity, risks of institutionalization after fractures of pelvis (relative risk (RR), 0.94; 95% confidence interval (CI) 0.86; 1.02 in women and 0.89; 95% CI 0.70; 1.12 in men), and spine (RR, 0.95; 95% CI 0.87; 1.03 in women and 0.91; 95% CI 0.76; 1.08 in men) were not statistically different compared to the risk after hip fracture. CONCLUSIONS: The risk of institutionalization after fractures of the spine and pelvis was similar to the risk after hip fracture. These fracture sites seem to be associated with a significant decline in physical function.

Longitudinal assessment of health-related quality of life in osteoporosis: data from the population-based Canadian Multicentre Osteoporosis Study.

Little is known about the association between health-related quality of life (HRQOL) and osteoporosis in the absence of fracture, and how HRQOL may change over time. This study provides evidence of substantially reduced HRQOL in women and men with self-reported and/or BMD-confirmed osteoporosis, even in the absence of fragility fracture. INTRODUCTION: Fragility fractures have a detrimental effect on the health-related quality of life (HRQOL) of those with osteoporosis. Less is known about the association between HRQOL and osteoporosis in the absence of fracture. METHODS: Canadian Multicentre Osteoporosis Study participants completed the SF-36, a detailed health questionnaire and measures of bone mineral density (BMD) at baseline and follow-up. We report the results of participants ≥ 50 years with 10-year follow-up. Self-reported osteoporosis at baseline and BMD-based osteoporosis at follow-up were ascertained. Multivariable linear regression models were developed for baseline SF-36 domains, component summaries, and change over time, adjusting for relevant baseline information. RESULTS: Baseline data were available for 5266 women and 2112 men. Women in the osteoporosis group had substantially lower SF-36 baseline scores, particularly in the physically oriented domains, than those without osteoporosis. A similar but attenuated pattern was evident for the men. After 10-year follow-up (2797 women and 1023 men), most domain scores dropped for women and men regardless of osteoporosis status, with the exception of mentally-oriented ones. In general, a fragility fracture was associated with lower SF-36 scores and larger declines over time. CONCLUSIONS: This study provides evidence of substantially reduced HRQOL in women and men with self-reported and/or BMD-confirmed osteoporosis, even in the absence of fragility fracture. HRQOL should be thoroughly investigated even prior to fracture, to develop appropriate interventions for all stages of the disease.

Impact of mild and moderate/severe vertebral fractures on physical activity: a prospective study of older women in the UK.

Little is known about the long-term impact of vertebral fractures on physical activity. There is also uncertainty over the clinical significance of mild vertebral fracture. We showed that women with moderate/severe but not mild vertebral fracture do less walking duration and housework than those without fracture after 5.4 years of follow-up. INTRODUCTION: Little is known about the long-term impact of vertebral fractures on physical activities. There is also uncertainty over the clinical significance of mild fracture. Therefore, the aim of this study was to evaluate the prospective association between vertebral fracture and future physical activity. METHODS: This is a 5-year prospective study of a mixed community and secondary care cohort of women aged > 50 from the UK. Vertebral fractures were identified at baseline on radiographs or DXA-based Vertebral Fracture Assessment by a Quantitative Morphometric approach and defined as moderate/severe (≥ 25% height decrease) or mild (20-24.9% height decrease). Physical activity data were collected 5.4 years later by self-completion questionnaires. Multivariable logistic regression was used to determine the association between presence of fracture and various physical activities while adjusting for potential confounders. RESULTS: Two hundred eighty-six women without, 58 with mild, and 69 with moderate/severe fracture were recruited. Those with mild and moderate/severe fracture were older than women without fracture and had more concomitant diseases at baseline. At 5.4 years follow-up, women with moderate/severe fracture self-reported shorter walking duration compared to those without fracture, even after adjusting for potential confounders (OR 2.96, 95%CI 1.11-7.88, P = 0.030). No independent association was seen between the presence of mild fractures and reduced physical activity at follow-up. CONCLUSION: This is the first study of older women from the UK that explored the prospective association between vertebral fracture and physical activity duration. Moderate/severe fractures were associated with reduced walking duration. Mild fractures had no impact on future physical ability.

Health-related quality of life in children with osteogenesis imperfecta: a large-sample study.

In this large-sample study, we demonstrated that osteogenesis imperfecta (OI) significantly impaired the quality of life (QoL) in children. Moderate/severe OI patients had worse QoL scores than patients with mild OI. Furthermore, the QoL for OI patients was correlated with the presence of pathogenic gene mutations. INTRODUCTION: Osteogenesis imperfecta (OI) is a hereditary disease characterized by multiple fragility fractures and progressive skeletal deformities. No detailed investigations about the quality of life (QoL) have been carried out in a large sample of patients with OI. We evaluated the QoL and its influencing factors in a large and well-characterized OI cohort. METHODS: We used a validated questionnaire of PedsQL 4.0 to evaluate the health-related quality of life (HRQoL) of children and adolescents with OI. We compared HRQoL among patients with OI types I, III, and IV. The relationship between HRQoL and pathogenic mutations in candidate OI genes was investigated. We also evaluated the influencing factors of HRQoL in OI patients. RESULTS: A total of 138 children with OI and 138 healthy controls were enrolled in this study. The HRQoL scores of OI patients were 64.4 ± 30.0, 71.9 ± 22.2, 75.7 ± 24.8, 63.7 ± 24.5, and 68.9 ± 22.0 in physical, emotional, social, school functioning, and total score, respectively, which were significantly lower than those of healthy children (86.5 ± 12.7, 83.3 ± 16.0, 92.1 ± 11.8, 87.5 ± 11.8, and 87.3 ± 10.7, all p < 0.01). Moderate and severe OI (type III/IV) patients had poorer HRQoL scores than patients with mild OI (type I). Gene mutations inducing qualitative defects in type I collagen led to worse HRQoL scores than those with quantitative defects in type I collagen, except in emotional functioning. The total HRQoL score was positively correlated with family income, lumbar, and femoral bone mineral density (BMD) Z-scores and negatively correlated with disease severity and fracture frequency. CONCLUSION: HRQoL was significantly impaired in OI patients, and patients with more severe OI had poorer HRQoL scores. For the first time, we found that children with qualitative defects in type I collagen had poorer HRQoL scores than those with quantitative defects in type I collagen.

Decreased physical health-related quality of life-a persisting state for older women with clinical vertebral fracture.

In a population-based study of older Swedish women, we investigated if clinical vertebral fracture was associated with lower health-related quality of life (HRQoL) and determined whether the association remained over time. Clinical vertebral fracture was associated with lower HRQoL and the effect persisted for up to 18.9 years. INTRODUCTION: Vertebral fractures are often associated with back pain and reduced physical function, which might result in isolation and depression. As a result, women with vertebral fractures often have lower health-related quality of life (HRQoL), but during what time frame the decrease lingers is unclear. Therefore, the aim of this study was to investigate if clinical vertebral fracture and hip fracture were associated with lower HRQoL and to determine whether the associations remained over time. METHODS: Vertebral fracture assessments (VFA) were performed using dual-energy X-ray absorptiometry. Data regarding prior fractures, medications, medical history, and physical activity was collected using a questionnaire. Self-rated physical HRQoL was assessed using the 12-Item Short-Form Health Survey (SF-12). Women with clinical vertebral fractures were divided into tertiles according to time since fracture onset and their HRQoL was compared with non-fractured women. RESULTS: In a population-based cross-sectional study of 3028 women aged 77.8 ± 1.63 (mean ± SD), a total of 130 (4.3%) women reported at least one clinical vertebral fracture. Women with a clinical vertebral fracture, divided into tertiles (T1-T3) depending on time since the fracture occurred, had lower HRQoL (T1: 36.3 ± 10.8; T2: 41.0 ± 9.94; and T3:41.6 ± 11.4) than women without fracture (46.2 ± 10.6; p < 0.001). Using linear regression analysis, clinical vertebral fracture was associated with reduced physical HRQoL for up to 18.9 years, independently of covariates (age, height, weight, smoking, prior stroke, mental HRQoL, grip strength, and lumbar spine BMD). CONCLUSIONS: Clinical vertebral fracture was associated with lower self-rated physical HRQoL, for up to 18.9 years after time of fracture.

Association of Back Pain with All-Cause and Cause-Specific Mortality Among Older Women: a Cohort Study.

BACKGROUND: The impact of back pain on disability in older women is well-understood, but the influence of back pain on mortality is unclear. OBJECTIVE: To examine whether back pain was associated with all-cause and cause-specific mortality in older women and mediation of this association by disability. DESIGN: Prospective cohort study. SETTING: The Study of Osteoporotic Fractures. PARTICIPANTS: Women aged 65 or older. MEASUREMENT: Our primary outcome, time to death, was assessed using all-cause and cause-specific adjusted Cox models. We used a four-category back pain exposure (no back pain, non-persistent, infrequent persistent, or frequent persistent back pain) that combined back pain frequency and persistence across baseline (1986-1988) and first follow-up (1989-1990) interviews. Disability measures (limitations of instrumental activities of daily living [IADL], slow chair stand time, and slow walking speed) from 1991 were considered a priori potential mediators. RESULTS: Of 8321 women (mean age 71.5, SD = 5.1), 4975 (56%) died over a median follow-up of 14.1 years. A higher proportion of women with frequent persistent back pain died (65.8%) than those with no back pain (53.5%). In the fully adjusted model, women with frequent persistent back pain had higher hazard of all-cause (hazard ratio [HR] = 1.24 [95% CI, 1.11-1.39]), cardiovascular (HR = 1.34 [CI, 1.12-1.62]), and cancer (HR = 1.33, [CI 1.03-1.71]) mortality. No association with mortality was observed for other back pain categories. In mediation analyses, IADL limitations explained 47% of the effect of persistent frequent back pain on all-cause mortality, slow chair stand time, and walking speed, explained 27% and 24% (all significant, p < 0.001), respectively. LIMITATIONS: Only white women were included. CONCLUSION: Frequent persistent back pain was associated with increased mortality in older women. Much of this association was mediated by disability.

Outcome of femoral fractures in poliomyelitis patients.

BACKGROUND AND PURPOSE: As patients who were afflicted with poliomyelitis during the outbreaks in the past are aging, lower extremity osteoporotic fractures are becoming more frequent. Fixation in deformed, porotic bone, coupled with muscle weakness and imbalance creates a unique challenge when treating these fractures as does their reduced rehabilitation potential. The aim of this study was to investigate the outcome of femoral fractures in surviving poliomyelitis patients. PATIENTS AND METHODS: Sixty-five patients with 74 femoral fractures were treated between 1990 and 2014. Clinical outcome was assessed using the Parkland and Palmer mobility score, and quality-of-life was assessed using the SF-12® score. RESULTS: Some 84% of the fractures were a result of low-energy mechanisms and occurred in the polio-affected limbs, but nonaffected limbs were also injured owing to low-energy mechanisms in all cases. Fifty-seven fractures were treated operatively. There were nine re-operations (16%), including implant removals, nonunion, peri-implant fractures, and malunion. Some 60% of the patients did not regain their previous ambulatory capacity. Post-operative weight-bearing status did not correlate with the final functional outcome. CONCLUSIONS: Polio patients with femoral fractures have a guarded prognosis for regaining their pre-injury ambulatory capacity. A higher re-operation rate than that with "normal" osteoporotic fractures is expected.

Quality of life for up to 18 months after low-energy hip, vertebral, and distal forearm fractures-results from the ICUROS.

This study used data from the International Costs and Utilities Related to Osteoporotic fractures Study (ICUROS) to estimate the quality of life (QoL) impact of fracture. Hip, vertebral, and distal forearm fractures incur substantial QoL losses. Hip and vertebral fracture results in markedly impaired QoL for at least 18 months. INTRODUCTION: The International Costs and Utilities Related to Osteoporotic fractures Study (ICUROS) is a multinational observational study that aims to describe costs and quality of life (QoL) consequences of osteoporotic fractures. To date, 11 countries have participated in the study: Australia, Austria, Estonia, France, Italy, Lithuania, Mexico, Russia, Spain, the UK, and the USA. The objective of this paper is to describe the QoL impact of hip, vertebral, and distal forearm fracture. METHODS: Data were collected at four time-points for five QoL point estimates: within 2 weeks after fracture (including pre-fracture recall) and at 4, 12, and 18 months after fracture. Quality of life was measured as health state utility values (HSUVs) derived from the EQ-5D-3L. Complete case analysis was conducted as the base case with available case and multiple imputation performed as sensitivity analyses. Multivariate analysis was performed to explore predictors of QoL impact of fracture. RESULTS: Among 5456 patients enrolled using convenience sampling, 3021 patients were eligible for the base case analysis (1415 hip, 1047 distal forearm, and 559 vertebral fractures). The mean (SD) difference between HSUV before and after fracture for hip, vertebral, and distal forearm fracture was estimated at 0.89 (0.40), 0.67 (0.45), and 0.48 (0.34), respectively (p < 0.001 for all fracture types). Eighteen months after fracture, mean HSUVs were lower than before the fracture in patients with hip fracture (0.66 vs. 0.77 p < 0.001) and vertebral fracture (0.70 vs. 0.83 p < 0.001). Hospitalization and higher recalled pre-fracture QoL were associated with increased QoL impact for all fracture types. CONCLUSIONS: Hip, vertebral, and distal forearm fractures incur substantial loss in QoL and for patients with hip or vertebral fracture, QoL is markedly impaired for at least 18 months.

Health-related quality of life during the first year after a hip fracture: results of the Mexican arm of the International Cost and Utility Related to Osteoporotic Fractures Study (MexICUROS).

We investigated changes in health-related quality of life (HRQoL) due to hip fracture in Mexican adults aged ≥ 50 years during the first year post-fracture. Mean accumulated loss was 0.27 quality-adjusted life years (QALYs). HRQoL before fracture was the main contributor to explain the loss of QALYs. INTRODUCTION: We aimed to estimate the health-related quality of life (HRQoL) loss over 1 year in patients sustaining a hip fracture in Mexico. METHODS: Individuals aged ≥ 50 years old with diagnosis of a low-energy-induced hip fracture enrolled in the International Costs and Utilities Related to Osteoporotic Fractures Study (ICUROS) composed the study population. After a recall of their own pre-fracture status, HRQoL was prospectively collected in three phases over 12 months of follow-up using EQ-5D-3L. The UK preference weight set was applied to calculate the utility values. The accumulated quality-adjusted life years (QALYs) loss in the first year post-fracture was estimated using the trapezoid method. Multivariate regression analysis allowed identifying determinants of QALYs loss. RESULTS: One hundred ninety-three patients (mean ± SD age 77.2 ± 9.9 years; 80% women; 15.5% with prior fracture in the last 5 years; 78% in low-income category) were evaluated. Mean (95% CI) utility value before fracture was 0.64 (0.59-0.68). It dropped to 0.01 (0.01-0.02) immediately after fracture and then improved to 0.46 (0.42-0.51) and 0.60 (0.55-0.64) at 4 and 12 months post-fracture, respectively. Disregarding fracture-related mortality, accumulated QALYs loss over the first year was 0.27 (0.24-0.30) QALYs. Mobility, self-care, and usual activities were the most affected domains throughout the whole year. HRQoL before fracture was the main contributor to explain the loss of QALYs. CONCLUSIONS: Hip fractures reduce dramatically the HRQoL, with the loss sustained at least over the first year post-fracture in Mexico. The utility values derived from this study can be used in future economic evaluations.

Systematic review and meta-analysis of prevalence of sarcopenia in post acute inpatient rehabilitation.

Sarcopenia is associated with poor function and increased risk of falls and disability. This work reports a systematic review and meta-analysis of prevalence of sarcopenia in post acute inpatient rehabilitation. Sarcopenia is found to be present in approximately 50% of rehabilitation patients and its prevalence may vary with admission diagnosis. PURPOSE: To conduct a systematic review and meta-analysis of reported prevalence of sarcopenia in post acute inpatient rehabilitation. METHODS: Systematic review conducted according to PRISMA guidelines (PROSPERO registration number CRD42016054135). Databases searched MEDLINE, EMBASE, Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials (CENTRAL), Cochrane Methodology Register, and CINAHL. Studies considered the following: published January 1988-February 2017. Key terms are as follows: "sarcopenia" AND "inpatient rehabilitation" OR "rehabilitation" AND/OR "prevalence". Abstracts and subsequently full studies reporting sarcopenia prevalence in adults admitted to rehabilitation reviewed irrespective of design, provided sarcopenia diagnosis included at least assessment of muscle mass. Random effect meta-analysis was conducted. Methodological quality assessment: Agency for Healthcare Research and Quality, US Department of Health and Human Services tool (MORE tool); Joanna Briggs Institute Prevalence Critical Appraisal Tool. RESULTS: Four hundred twenty-six studies identified during initial search, 399 excluded after reviewing titles and abstracts, 21 full text articles reviewed, and six studies met inclusion criteria. Patient populations: after hip fracture (five studies), general deconditioning (one study). Identified sarcopenia prevalence ranged from 0.28 to 0.69. Pooled sarcopenia prevalence obtained with random effect meta-analysis: 0.56 (95% CI 0.46-0.65), heterogeneity I2 = 92.9%. Main quality shortcomings: lack of reporting of inter- and intra-rater reliability, lack of generalizability to other rehabilitation populations. CONCLUSIONS: Original research examining sarcopenia prevalence in inpatient rehabilitation is scarce. Patient populations studied to date are not representative of general rehabilitation population with regard to both age and admission diagnoses. Sarcopenia may be present in approximately half of rehabilitation patients and its prevalence may vary with admission diagnosis.

Long-term experiences of pain after a fragility fracture.

Little is known about long-term pain after a fragility fracture. In this secondary analysis, we determined that pain continues to influence many patients' lives more than 1 year after a fracture and that health care providers do not seem to adequately recognize or manage these long-term consequences. INTRODUCTION: We characterized perspectives on long-term pain among men and women who had sustained a fragility fracture. METHODS: We conducted a secondary analysis of qualitative data from 67 individuals recruited in three primary studies (47-89 years old; 55 women, 12 men). Eligible individuals from the primary studies were those who had reported pain related to their fracture beyond 6 months. Data about reported pain were re-analyzed using qualitative description as articulated by Sandelowski. RESULTS: Thirty-four individuals (47-89 years old; 4 men; 8 had sustained a vertebral fracture) reported pain related to their fracture in the primary studies. Thirty-one (91%) participants had sustained a fragility fracture at least 1 year previously (range 1-13 years). Patients described long-term pain beyond typical fracture healing times, generally unrelieved by analgesics, which affected their mobility, functional activity, independence, sleep, and energy. Health care providers were perceived to under-estimate timelines regarding the decrease of post-fracture pain and to not manage that pain. Participants reported that pain management was inadequate and that they developed their own strategies to respond to it. CONCLUSIONS: Pain continues to influence many patients' lives more than 1 year after a fragility fracture. Patient narratives could be useful to help health care providers to better recognize and manage this long-term consequence of fractures.

Vertebral fractures and their association with health-related quality of life, back pain and physical function in older women.

Studies investigating prevalent vertebral fracture (VF) diagnosed using densitometry-based VF assessment (VFA) and associations with physical function, assessed by performance-based measures, are lacking. In this population-based study of 1027 older women, we found that prevalent VF, identified by VFA, was associated with inferior physical health, back pain and inferior physical function. PURPOSE: Several studies have investigated the associations between health-related quality of life (HRQL) and back pain with prevalent VF, detected by spine radiographs, but just a few have been population-based and have used vertebral fracture assessment (VFA) for diagnosing VF. The aims of this study were to investigate associations between prevalent VF, detected by VFA, with HRQL, back pain and physical function, and investigate if also mild VFs were associated with these clinical parameters. METHODS: One thousand twenty-seven women aged 75-80 years participated in this population-based cross-sectional study. VF was identified by VFA using dual-energy X-ray absorptiometry. HRQL was assessed by SF-12, back pain during the past 12 months using a questionnaire, and physical function was tested with one leg standing (OLS), Timed Up and Go (TUG), walking speed, 30-s chair stand test and maximum grip strength. RESULTS: Physical health (Physical Component Summary, PCS), derived from SF-12, was worse (43.5 ± 11.3 vs. 46.2 ± 10.5, p < 0.001) and back pain more frequent in women with any VF than in women without (69.0 vs. 59.9%, p = 0.008). PCS and physical function (OLS, 30-s chair stand test), were significantly worse for mild VF compared to no VF (43.8 ± 10.9 vs. 46.2 ± 10.5, p < 0.001, 12.7 ± 9.9 vs. 15.3 ± 10.4 s, p = 0.038, 10.7 ± 3.2 vs. 11.4 ± 3.4 times, p = 0.021, respectively). In multivariable adjusted linear regression models, VF prevalence was associated with PCS (ß = - 0.079, p = 0.007), TUG (ß = 0.067, p = 0.021), walking speed (ß = - 0.071, p = 0.009) and 30-s chair stand test (ß = - 0.075, p = 0.012). CONCLUSIONS: In conclusion, prevalent VF, diagnosed by VFA, was associated with inferior physical health, back pain and inferior physical function, indicating VFA is useful for diagnosing clinically relevant vertebral fractures. Also, mild VF was associated with inferior physical health and inferior physical function.

Changes in inflammatory factors in patients with osteoporotic vertebral compression fracture and influences of rehabilitation training on postoperative functional recovery and inflammation.

OBJECTIVE: To observe the changes in inflammatory factors in patients with osteoporotic vertebral compression fracture (OVCF). METHODS: 40 OVCF patients meeting inclusion criteria were collected, and randomly divided into rehabilitation therapy group (n=20) and traditional therapy group (n=20). 20 normal subjects were collected as control group. Venous blood was collected after admission, and the expression levels of IL-1 and IL-18 were detected via ELISA. Patients in rehabilitation therapy group received rehabilitation training post-operatively, while those in traditional therapy group received conventional therapy. The pain was evaluated using visual analogue scale (VAS) score, and the spinal function was evaluated using Oswestry disability index (ODI) score. The curative effect was evaluated at final follow-up. RESULTS: The expression levels of IL-1 and IL-18 of OVCF patients were significantly higher than those in normal subjects (p<0.01). The VAS and ODI scores in the rehabilitation therapy group were significantly lower than those in traditional therapy group from the 3rd month after operation (p<0.05). The expression levels of IL-1 and IL-18 in the rehabilitation therapy group were obviously lower than those in traditional therapy group from the 3rd month after operation (p<0.05). The effective rate in rehabilitation therapy group was higher than that in traditional therapy group. The expression levels of IL-1 and IL-18 in OVCF patients are increased. CONCLUSION: Rehabilitation training is beneficial to functional recovery and reduction of inflammation after OVCF operation.

The impact of fragility fractures on work and characteristics associated with time to return to work.

We examined the impact of fragility fractures on the work outcomes of employed patients. The majority successfully returned to their previous jobs in a short amount of time, and productivity loss at work was low. Our findings underscore the fast recovery rates of working fragility fracture patients. INTRODUCTION: The purpose of this study is to describe the impact of fragility fractures on the work outcomes of patients who were employed at the time of their fracture. METHODS: A self-report anonymous survey was mailed to fragility fracture patients over 50 who were screened as part of the quality assurance programs of fracture clinics across 35 hospitals in Ontario, Canada. Measures of return to work (RTW), at-work productivity loss (Work Limitations Questionnaire), and sociodemographic, fracture-related, and job characteristics were included in the survey. Kaplan-Meier estimates of the cumulative proportion of patients still off work were computed. Factors associated with RTW time following a fragility fracture were examined using Cox proportional hazards modeling. RESULTS: Of 275 participants, 242 (88 %) returned to work. Of these, the median RTW time was 20.5 days. About 86 % returned to the same job, duties, and hours as before their injury. Among full-time workers, the median number of lost hours due to presenteeism was 2.9 h (Q1-Q3 0.4-8.1 h). The median cost of presenteeism was $75.30 based on the month prior to survey completion. In multivariable analyses, female gender, needing surgery, and medium/heavy work requirements were associated with longer RTW time. Earlier RTW time was associated with elbow fracture and feeling completely better at time of survey completion. CONCLUSIONS: The majority of fragility fracture patients successfully returned to their previous jobs in a short amount of time, and productivity loss at work was low. Our findings underscore their fast recovery rates and give reason for optimism regarding the resilience of this population.

Estimating the long-term functional burden of osteoporosis-related fractures.

Although fractures are associated with short-term reductions in functional status, there is limited information on longer-term burden of fracture. This study documents evidence of an association between fractures and significant declines and functional health and activities that persist but attenuate beyond two years. INTRODUCTION: Although fractures are associated with short-term reductions in functional status and may have other short-term effects on healthcare utilization (hospitalization and follow-up care), there is limited information on long-term burden of fracture beyond 12 to 24 months post-fracture. Analysis of the long-term health burden can inform policymakers, health care practitioners, and payers. METHODS: We acquired a data set containing the 1992-2012 Health and Retirement Survey data linked to the same individuals' Medicare claims. Fracture cases (n = 745) were matched to non-fracture controls using propensity scores matching. A regression-adjusted difference-in-difference (DD) approach was used to compare the change in functional status measures from baseline to two post-fracture periods for fracture cases relative to the change over the same time periods for matched controls. Self-reported measures of functional status were examined: limitations to activities of daily living (ADLs), limitations to instrumental activities of daily living (IADLs), a mobility index, a gross motor skills index, a fine motor skills index, and self-reported general health status. RESULTS: Fracture cases reported increases in limitations to ADLs, difficulties with mobility, difficulties with gross motor skills, and difficulties with fine motor skills in each HRS collection period (the survey is administered every 2 years) following the fracture or index date (thus up to two years later) than matched controls (all p values < 0.05). The magnitude of these effects diminished in the second post-fracture wave (two to four years after fracture/index date), but they were still statistically significant. CONCLUSIONS: Results suggest that fractures are associated with significant declines in some measures of functional activities up to two years following the fracture. The effects persist beyond two years but are smaller in magnitude.

The importance of physical function to people with osteoporosis.

There is increasing need to understand patient outcomes in osteoporosis. This article discusses that fracture in osteoporosis can lead to a cycle of impairment, driven by complex psychosocial factors, having a profound impact on physical function/activity which accumulates over time. More information is required on how treatments impact physical function. INTRODUCTION: There is increasing need to understand patient-centred outcomes in osteoporosis (OP) clinical research and management. This multi-method paper provides insight on the effect of OP on patients' physical function and everyday activity. METHODS: Data were collected from three sources: (1) targeted literature review on OP and physical function, conducted in MEDLINE, Embase and PsycINFO; (2) secondary thematic analysis of transcripts from patient interviews, conducted to develop a patient-reported outcome instrument. Transcripts were re-coded to focus on OP impact on daily activities and physical function for those with and without fracture history; and (3) discussions of the literature review and secondary qualitative analysis results with three clinical experts to review and interpret the importance and implications of the findings. RESULTS: Results suggest that OP, particularly with fracture, can have profound impacts on physical function/activity. These impacts accumulate over time through a cycle of impairment, as fracture leads to longer term detriments in physical function, including loss of muscle, activity avoidance and reduced physical capacity, which in turn leads to greater risk of fracture and potential for further physical restrictions. The cycle of impairment is complex, as other physical, psychosocial and treatment-related factors, such as comorbidities, fears and beliefs about physical activity and fracture risk influence physical function and everyday activity. CONCLUSION: More information on how treatments impact physical function would benefit healthcare professionals and persons with OP in making treatment decisions and improving treatment compliance/persistence, as these impacts may be more salient to patients than fracture incidence.

Health state utility values and patient-reported outcomes before and after vertebral and non-vertebral fractures in an osteoporosis clinical trial.

We assessed the health state utility value (HSUV) reductions associated with vertebral fractures using data collected in the Japanese Osteoporosis Intervention Trial-03 (JOINT-03). Our analysis revealed that assessment of HSUVs after morphometric vertebral fracture is important to capture the burden of vertebral fractures. INTRODUCTION: Evaluation of the HSUV after fracture is important to calculate the quality-adjusted life years (QALYs) of osteoporosis patients, which is essential information in the context of health economic evaluation. METHODS: JOINT-03 study patients were aged ≥65 years and treated with risedronate and vitamin K2 or risedronate alone. Radiographic information and patient-reported outcomes measured by EQ-5D and a visual analogue scale (VAS) were assessed at registration and followed up after 6, 12, and 24 months. According to differences among the dates of these assessments and the radiographic information, we classified the follow-up HSUVs calculated based on EQ-5D results into before or after fracture categories regardless of clinical symptoms. RESULTS: Among 2922 follow-up HSUVs, 201 HSUVs were categorized as HSUVs that were observed after incident vertebral fractures on X-ray films. The median time from the detection of an incident vertebral fracture until the EQ-5D assessment was 53 days (25th percentile, 0 day; 75th percentile, 357 days). The impact of incident vertebral fractures on HSUVs was quantified as -0.03. Among the five health profile domains on the EQ-5D, an incident vertebral fracture had significant effects on anxiety/depression, self-care, and usual activities. CONCLUSIONS: The results suggest that incident morphometric vertebral fracture was associated with impairment of the HSUV for patients with osteoporosis not only immediately but also several months after the fracture.
