Abstract
Sexually dimorphic tissues are formed by cells that are regulated by sex hormones. While a number of systemic hormones and transcription factors are known to regulate proliferation and differentiation of osteoblasts and osteoclasts, the mechanisms that determine sexually dimorphic differences in bone regeneration are unclear. To explore how sex hormones regulate bone regeneration, we compared bone fracture repair between adult male and female mice. We found that skeletal stem cell (SSC) mediated regeneration in female mice is dependent on estrogen signaling but SSCs from male mice do not exhibit similar estrogen responsiveness. Mechanistically, we found that estrogen acts directly on the SSC lineage in mice and humans by up-regulating multiple skeletogenic pathways and is necessary for the stem cell's ability to self- renew and differentiate. Our results also suggest a clinically applicable strategy to accelerate bone healing using localized estrogen hormone therapy.

A System Review and Meta-Analysis on the Prognosis of Intertrochanteric Femoral Fractures Based on Randomized Controlled Trials. Geriatr Orthop Surg Rehabil 2022; 13:21514593221118212. [PMID: 35967750 PMCID: PMC9364206 DOI: 10.1177/21514593221118212] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/24/2022] [Revised: 06/29/2022] [Accepted: 07/18/2022] [Indexed: 11/20/2022] Open
Abstract
Introduction There is no consensus regarding the superiority between intramedullary nailing and
primary arthroplasty in the management of intertrochanteric femoral fractures. This
systematic review was performed to investigate and compare the clinical efficacy of
intertrochanteric femoral fractures treated with these 2 methods. Materials and methods We systematically searched PubMed, Embase, Cochrane, Web of science core collection and
ClinicalTrials.gov for randomized controlled trials which compared the clinical outcomes
of intertrochanteric fractures treated with either intramedullary nails or primary
arthroplasty. Relevant data of the postoperative complications, reoperations, mortality
and functional assessment, were pooled and presented graphically. Results A total of 6 trials with 427 participants were identified and included in the analyses.
The pooled estimates suggested these 2 techniques have comparable risks in terms of
overall complications (pooled risk ratio [RR] .80; 95% confidence interval [CI] .43 to
1.43; I2 = 79.94%), the rate of patients with orthopedic complications (RR
.71, 95% CI .40 to 1.27; I2 = .00%), reoperations (RR 1.33, 95% CI .48 to
3.71; I2 = .00%), the overall mortality (RR .52; 95%CI .26 to 1.02;
I2 = 31.35%) and 1-year mortality (RR .67; 95%CI .38 to 1.19; I2
= .00%). Primary arthroplasty associated with higher HHS at 3 months postoperatively (MD
-21.95, 95% CI -28.29 to −15.60; I2 = 70.44%). While the difference was not
significant at 6 months (MD 2.32, 95% CI -1.55 to 6.18; I2 = .00%), and even
reversed at 12 months postoperatively (MD 13.02, 95% CI 8.14 to 17.90; I2 =
73.42%). Conclusions Meta-analytic pooling of current evidences demonstrated that primary arthroplasty is
related to a better early functional recovery at the early stage postoperatively, but
the long-term result tends to favor to intramedullary nailing. The differences in
overall complications, the rate of patients with orthopedic complications, reoperations,
overall and 1-year mortality did not reach a significant level.

Abstract
Background Osteoporosis is a major global public health problem in the current aging era. Osteoporosis is often diagnosed only after patients have a fracture that causes a severe decline in ability to perform activities of daily life. Although the current criterion standard for diagnosing osteoporosis is dual-energy X-ray absorptiometry (DXA), this modality remains less prevalent among general practitioners in geriatric medicine. The aim of this study was to determine the diagnostic utility of visual inspection of lumbar radiography in detecting bone mineral density (BMD) decline. Material/Methods We retrospectively reviewed medical data of 78 patients who underwent both lateral lumbar radiography and DXA. Board-certified radiologists determined the clinical grade of each patient’s condition according to the semiquantitative (SQ) method of lumbar fracture assessment. We compared the grades and young adult means of BMD in the lumbar spine and hips as measured using DXA. Results BMD of the femoral neck was significantly lower in patients with severe osteoporosis (grades 2 and 3 as classified using the SQ method) than in those with mild osteoporosis (grades 0 and 1; P<0.05). A receiver operating characteristic curve analysis showed that the SQ method can help predict the decrease in BMD (young adult mean score of <70%) in the femoral neck with moderate accuracy (sensitivity, 0.621; specificity, 0.829; area under the curve, 0.742). Conclusions These results suggest that lateral lumbar radiography can provide useful information about bone mineral status and can serve as a tool for osteoporosis screening by general practitioners.

Abstract
Fracture is a type of musculoskeletal injury that contributes to an inability to perform daily activities. The objective of this study was to evaluate activities of daily living (ADL) of older adult patients with lower body fracture and to determine factors influencing ADL. Patient's ADL was assessed at pre-fracture, ward admission and post-discharge phases using the Katz ADL questionnaire. There were 129 subjects at pre-fracture and ward phases and 89 subjects at discharge phase. There were four independent variables; age, gender, type of fracture and ability to walk before fracture. Logistic regression models showed that 'age' and 'ability to walk before fracture' were the determinant factors of dependent for 'bathing', 'dressing' and 'toileting'. The 'ability to walk before fracture' was the determinant factor of dependent for 'transferring'. 'Age' and 'gender' were the determinant factors of dependent for 'continence', while 'age' was the determinant factor of dependent for 'feeding'. The ADL score changes were significant across the phases with a reduction in ADL score in the ward admission phase and partial increment during the post-discharge phase. There were improvements in the health outcomes of subjects aged more than 50 years old after 3 months of being discharged from the hospital. In conclusion, age, being female, having a hip fracture and using a walking aid before fracture were the determinants identified in this study.

Abstract
Sixty-one individuals hospitalized for hip fractures received activities of daily living (ADL) assessments during the 3 days prior to discharge. Information was also collected regarding anticipated role loss, depression, mental status, health status, and social support. Independence in ADL at home was measured 3 weeks following discharge by telephone interviews. The concordance between predischarge and post discharge ADL scores was low but statistically significant (Kw = .223; p < .05). Approximately 50.8% of the subjects demonstrated greater dependence post discharge. More dependent ADL performance at home was not related to role loss, depression, mental status, health status, or social support. Predischarge ADL assessments are often taken into consideration when formulating discharge plans. However, these evaluations do not always accurately predict post discharge ADL independence. It is recommended, therefore, that community follow-up be carried out with patients who have fractured hips.

Abstract
The objective of the study was to explore the relationships between rehabilitation outcomes in elderly patients admitted to a rehabilitation hospital following a surgically treated hip fracture and independent variables. Prefracture function, and independent patients' variables and particulars regarding the fracture were recorded. Functional and mental status as well as motivation and co-operativeness were assessed on admission to rehabilitation, during rehabilitation and six months after discharge. Data were transferred to structured questionnaires for analysis. A total of 112 patients with a mean age of 74.8 years, made up of 75% females and 25% males, were admitted consecutively for rehabilitation after a surgically treated hip fracture sustained in a fall, during a two-year period (1989-91). Of these, 11 patients (9.8 per cent) died during rehabilitation; 86% of the 101 survivors returned to their prefracture residence, but 25% of survivors had not attained their prefracture functional status by discharge. Motivation, co-operativeness and unimpaired mental function on admission to rehabilitation were found to be the most important determinants of satisfactory outcomes. It was concluded that attention should be paid to the elderly person who has sustained the fracture and not only to the fracture itself. Motivation and co- operativeness should be constantly monitored during the rehabilitation process.

Abstract
We examined the relationship ofprehospital and in-hospital variables to location one yearfollowinghipfracture in a sample of 84 community-residing subjects aged 60 and older, whose fractures were not due to metastatic cancer or other bone disease or severe trauma and who were treated surgically and discharged alive. Prehospital and in-hospital data were gathered through retrospective chart reviews and one-year data obtained through telephone interviews. At one year, 70 (83%) of subjects were living in the community, 11 (13%) were in a nursing home, and 3 (4%) had died. Logistic regression showed that location at discharge and persistent mental impairment (present at admission and throughout the hospitalization) significantly increased the odds of not residing in the community when other variables were controlled.

Abstract
PURPOSE Osteoporotic fracture is the main complication of osteoporosis. The current management is to discharge patients as early as possible so they can get back to their daily activities. Once discharged, there are three main issues relating to morbidity, mortality, and risk of a subsequent fracture that need to be addressed and discussed. Therefore, the aim of this systematic review was to summarize and evaluate the evidence from published literature, to determine the outcome of osteoporotic fracture patients after their hospital discharge. METHODS The MEDLINE and Cumulative Index to Nursing and Allied Health Literature (CINAHL) databases were searched, using the terms "osteoporosis", "fracture", "osteoporotic fracture", "hip fracture", and "vertebral fracture". We included only human studies published in English between 2004 and 2014. The reference lists of included studies were thoroughly reviewed in search for other relevant studies. RESULTS A total of 18 studies met the selection criteria. Most were observational and cohort studies. Out of all the studies, five studies looked into the morbidity, six studies looked into the risk of subsequent fractures, and seven studies looked into mortality. Vertebral fracture caused the greatest health burden, but hip fracture patients were the main users of informal care after hospital discharge. There was an increased risk of a subsequent fracture after a primary fracture compared with the control group, a cohort comparison, or the general population. Osteoporotic fractures, especially hip fractures, are associated with higher mortality rate despite the advances in the management of osteoporotic fracture cases. CONCLUSION There is strong evidence to show that after hospital discharge, osteoporotic fracture patients are faced with higher morbidity, subsequent fractures, and mortality.

Abstract
BACKGROUNDS AND AIMS To examine the contribution of patient body mass index to functional status, physical independence and emotional distress in various age groups (third and fourth age) of female hip-fracture patients. METHODS A sample of 123 older females (>65 years) admitted in a major regional hospital with a diagnosis of hip fracture participated in this cross-sectional study. The outcome measures used in this study were body mass index (BMI), the Modified Barthel Index, the Goldberg General Health Questionnaire, the Tinetti Mobility Test and a survey collecting data from participants 24-72 h after admission. For our analysis, patients were divided into two groups according to their age: <80 years (third age) and >81 years (fourth age). In addition, three groups were made according to patients' body mass index <24 h prior to surgery: a normal weight group, an overweight group and an obese group. An ANCOVA was performed with age group as a between-subjects variable (third age, fourth age) and gender, educational level, marital status, type of fracture, type of surgery, presence of other fractures and BMI as covariates. RESULTS Patients in the third-age group obtained significantly higher values in the Barthel Index (P = 0.040) and the Tinetti Mobility Test (P = 0.001) and lower values in the Goldberg General Health Questionnaire (P = 0.035) compared to the fourth-age group. When BMI was considered, significance was maintained only in the Tinetti Mobility Test. CONCLUSIONS The BMI could be a relevant mediator of the relationship between functional decline and the aging process in the transition between third to fourth age in females.

Abstract
INTRODUCTION Studies yield conflicting results from the effect of early surgery on mortality. Some observed a positive, others a negative and some did not find any effect of early operation. In this study, mortality and quality of life in relation to time until surgery as well as reasons for delay were observed prospectively. MATERIAL AND METHODS Data of 138 patients (>65 years) with proximal femoral fractures and consecutive surgery were observed. Demographic data as well as mortality rate, survival time and Barthel Index up to 1 year in relation to different time frames were observed. Reasons for operative delay were divided into being administrative or patient-related. RESULTS Three-month mortality was 10.1% and 1-years was 23.9%. Neither time from injury until hospital admission nor from injury until surgery or from hospital admission until surgery up to 48 hours had any effect on mortality and survival time. The age of patients dying in the follow-up period was significantly higher than the age of patients surviving (86.8 vs. 84.4 years). No influence of any delay in time until surgery on the Barthel Index was observed. CONCLUSION In proximal femoral fractures, a delay of surgery up to 48 hours did not influence mortality and Barthel Index negatively, nor did other associating factors. Only the patients age at the time of injury influences mortality rate, survival time, and Barthel Index significantly. The older the patient at the time of injury; the higher the mortality rate, the shorter the survival time and the lower the Barthel Index.

Increased age is not associated with higher incidence of complications, longer stay in acute care hospital and in hospital mortality in geriatric hip fracture patients. Maturitas 2012; 74:185-9. [PMID: 23218684 DOI: 10.1016/j.maturitas.2012.11.003] [Citation(s) in RCA: 34] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2012] [Revised: 11/09/2012] [Accepted: 11/11/2012] [Indexed: 11/15/2022]
Abstract
The number of agile patients in the 10th decade with a strong need for postoperative mobility will increase in the following decades. The present prospective study sought to prove if very old patients with hip-related fractures are disadvantaged according to incidence of complications, length of ICU and in-hospital stay, and in-hospital mortality. We included 402 patients, age 60 years and older, with hip related fractures. Operative treatment consisted of osteosynthesis or endoprothesis. ASA score, body mass index, Charlson Comorbidity Index, Barthel Index and Mini-Mental-Status were documented. We noted length of in-hospital stay and ICU stay as well as readmission to ICU and complications, including their dispersal according to Clavien-Dindo Classification. After univariate analysis, a multivariate analysis was performed. The examined cohorts were 85 patients aged 60-74 years, 253 75-90 years old and 64 >90 year old patients. In-hospital periods (13-14 days) mean stay on ICU (2 days) and frequency of readmission on ICU did not significantly differ statistically. Most complications were grade II, with comparable frequency and modality, displaying no significant difference throughout age-related groups (p=0.461). In-hospital mortality showing significance (p=0.014) only between 75-89 (4.4%) and >90-year-old (12.5%) cohort. Nevertheless, according to multivariate analysis, including the common risk factors, increased age was not an independent risk factor for dying (p=0.132). Patients at an advanced age with hip-related fractures showed neither a prolonged in-hospital nor ICU stay. There was no significant relation of advanced age to number and type of complications.

Abstract
Background. The UK population is ageing with the largest increase expected to occur in people aged more than 85 years (85+). We have examined the hypothesis that neck of femur (NOF) fractures in the 85+ group exhibit demonstrable key outcome measurement differences after surgery when compared to a standard NOF population. Patients and Methods. A prospective observational cohort study of the demographics, clinical features, and key clinical outcome measurements for 2 groups of patients (65-84 and 85+ years of age at presentation) was performed in a single trauma unit over a 3-year period. Results. A total of 699 patients with a median age of 78 in the 65 to 84 cohort were compared with 523 patients with a median age of 88 in the 85+ cohort. Despite a dedicated orthogeriatric service and no difference in time to surgery between the 2 groups, the 30-day and 1-year mortality rates were significantly higher in the 85+ cohort at 10% and 30%, respectively, compared with 5% and 19% in the younger patient group. In our 85+ group, 34% had evidence of significant measured cognitive impairment compared to only 19% in the 65 to 84 group (P < .001). The length of hospital inpatient stay was also longer in the 85+ cohort with a median of 20 days compared to 16 days in the younger cohort (P = .001). In the 85+ cohort, 60% of patients were discharged back to their usual (preinjury) place of residence compared to 72% in the 65 to 84 cohort (P = .001). Conclusions. Patients in 85+ group presenting with an NOF fracture represent a unique high-risk patient group. Despite adherence to published key principles of care, this group is at higher risk and as such merits focused clinical attention, with adequate patient and family member counseling with regard to prognosis and overall expectation.

Abstract
We compared case-mix and outcome variables in 1310 patients who sustained an acute fracture at the age of 80 years or over. A group of 318 very elderly patients (≥ 90 years) was compared with a group of 992 elderly patients (80 to 89 years), all of whom presented to a single trauma unit between July 2007 and June 2008. The very elderly group represented only 0.6% of the overall population, but accounted for 4.1% of all fractures and 9.3% of all orthopaedic trauma admissions. Patients in this group were more likely to require hospital admission (odds ratio 1.4), less likely to return to independent living (odds ratio 3.1), and to have a significantly longer hospital stay (ten days, p = 0.01). The 30- and 120-day unadjusted mortality was greater in the very elderly group. The 120-day mortality associated with non-hip fractures of the lower limb was equal to that of proximal femoral fractures, and was significantly increased with a delay to surgery > 48 hours for both age groups (p = 0.04). This suggests that the principle of early surgery and mobilisation of elderly patients with hip fractures should be extended to include all those in this vulnerable age group.

Abstract
Introduction Associated with the increase in the aging population, there is an increase in the incidence of hip fractures worldwide. Outcome following such fractures is affected by age of the patient. This study aims to assess the incidence and early outcome of hip fractures, comparing between different age groups. Methods Data of hip fractures collected over a period of five years was analysed. Patients were divided into three groups, group A (patients under the age of 64), group B (patients between 65 and 84 years of age), and group C (patients over the age of 85). Results Of the 1177 patients included in the study, there were 90 patients in group A, 702 patients in group B and 385 patients in group C. There was a female preponderance across all age groups, and this increased as age advanced (p < 0.0001). A significantly larger number of older patients lived alone and needed aids to walk before the injury (p < 0.0001). There was no significant difference in the type of fracture across the three groups (p = 0.13). A higher proportion of the elderly with intracapsular fractures were treated by replacement arthroplasty. Older patients who had internal fixation of intracapsular fractures had a better walking ability at 4 months. The overall deterioration in mobility was greater in older patients (p < 0.0001). Mortality was higher in older patients. Conclusions Hip fractures are more common among females irrespective of age group. Older patients have a higher mortality and a greater deterioration of walking ability after such injuries. Internal fixation of intracapsular fractures have demonstrated satisfactory early outcome in the immediate period. This could be attributed to retention of native bone, better propioception and shorter operation time.

Abstract
OBJECTIVE To examine heterogeneity in 1-year functional recovery following postacute rehabilitation among older adults with hip fracture. METHODS Two hundred twenty-five community-dwelling older adults with hip fracture who received postacute rehabilitation in 5 rehabilitation facilities in Baltimore, Maryland, were recruited during postacute rehabilitation (baseline) and follow-up at 2, 6, and 12 months following postacute rehabilitation discharge. Functional recovery was measured by the activities of daily living (ADL) and instrumental activities of daily living (IADL) scores. A mixed-effect model was used to examine factors associated with postacute rehabilitation functional recovery; fixed and random effects estimates from the models were used to demonstrate heterogeneity in functional recovery. RESULTS Results indicated that there was an overall trend in both ADL and IADL functional improvement at 2 months following postacute rehabilitation, with continued improvement to 6 months, after which functional recovery slowed down and remained constant through the year. Individuals whose functional recovery did not conform to these patterns were identified and their functional recovery that deviated substantially from the group mean was demonstrated. CONCLUSIONS Functional recovery patterns in elderly hip fracture patients are heterogeneous. To foster functional independence, health care professionals should consider individual recovery trajectories using a modeling approach appropriate for longitudinal or repeated measurement data such as a linear mixed-effects model when designing individualized rehabilitation and postacute rehabilitation care plans.

Abstract
The purpose of this study was to determine the mortality rate and factors related to mortality in elderly patients with acute and monotraumatic femoral neck fractures. This study included 241 patients with femoral neck fractures after bipolar hemiarthroplasty. We analyzed the mortality rate and the relationship between postoperative mortality and risk factors, such as age, sex, body mass index, the time to surgery, and the Society of Anesthesiologists' score. The postoperative mortality rate 1 and 3 years after surgery was 11.2% and 19.5%, respectively. There proved to be a relationship between postoperative mortality and age, the time to surgery, and the Society of Anesthesiologists score. We recommend that surgery should not be delayed, and caution should be exercised for the high-risk group patients.

Abstract
BACKGROUND Osteoporosis is a serious but treatable condition. However, appropriate therapy utilization of the disease remains suboptimal. Thus, the objective of the study was to change physicians' therapy administration behavior in accordance with the Osteoporosis Canada 2002 guidelines. METHODS The Project was a two year cohort study that consisted of five Quality Circle (QC) phases that included: 1) Training & Baseline Data Collection, 2) First Educational Intervention & First Follow-Up Data Collection 3) First Strategy Implementation Session, 4) Final Educational Intervention & Final Follow-up Data Collection, and 5) Final Strategy Implementation Session. A total of 340 family physicians formed 34 QCs and participated in the study. Physicians evaluated a total of 8376, 7354 and 3673 randomly selected patient charts at baseline, follow-up #1 and the final follow-up, respectively. Patients were divided into three groups; the high-risk, low-risk, and low-risk without fracture groups. The generalized estimating equations technique was utilized to model the change over time of whether physicians RESULTS The odds of appropriate therapy was 1.29 (95% CI: 1.13, 1.46), and 1.41 (95% CI: 1.20, 1.66) in the high risk group, 1.15 (95% CI: 0.97, 1.36), and 1.16 (95% CI: 0.93, 1.44) in the low risk group, and 1.20 (95% CI: 1.01, 1.43), and 1.23 (95% CI: 0.97, 1.55) in the low risk group without fractures at follow-up #1 and the final follow-up, respectively. CONCLUSION QCs methodology was successful in increasing physicians' appropriate use of osteoporosis medications in accordance with Osteoporosis Canada guidelines.

Abstract
The centenarian population in England and Wales is the most rapidly increasing age group, yet we have little information as regards their acute hospital stay and delay in surgery after hip fracture. We reviewed the records of 26 centenarians with hip fracture between 2000 and 2007 and compared them to a randomly selected control group of 50 hip fracture patients between the ages of 75 and 85 years. The mean stay in acute orthopaedic wards for centenarians was 20.7 days and for the control group was 14.9 days (p=0.015). Centenarians had a mean delay in surgery of 3.6 days while non-centenarians were operated within a mean of 1.9 days, which was not statistically significant (p=0.241). The longer acute hospital stay in our centenarian cohort would amount to a mean extra cost of pound 2511 per patient.

Abstract
AIM To report the epidemiology and outcomes after hip fractures in the patients under 65 years of age. PATIENTS AND METHODS We performed a prospective, multi-centre observational study using the Scottish Hip Fracture Audit Database. Case-mix, process and outcome data was collected by dedicated coordinators on site at the time of admission, at 120 days after the injury and on any re-operations within 12 months. The study cohort consisted of 1896 individuals aged 50-64 years. Patient variables and outcomes were compared to a control group of 15,461 individuals aged 75-89 years of age. The control group consisted of three modal 5-year age groups centred about a median age of 83 years, equal to the database value, excluding the effects of the extreme elderly who may act as confounders. Outcomes measures included 30- and 120-day mortality, length of hospital stay, place of residence and ambulatory status. A multivariate logistic regression model was used to compare outcome between groups while controlling for significant case-mix variables. RESULTS Patients in the study cohort presented with lower ASA scores and were more likely to be independently mobile and live in their own home at the time of fracture (p<0.001). Pathological fractures were more common in younger patients and accounted for more than 1 in 20 fractures. Mortality at 30 and 120 days was significantly lower (p<0.0001) in the study cohort, however it was increased compared to age and gender adjusted mortality rates for the general population (p<0.001) Younger patients were more likely to recover independent mobility and living. CONCLUSION Patients aged 50-64 years have significantly better outcome measures after surgery for hip fracture in terms of survival and function. Such differences exist even after controlling for differences in patient case-mix variables.

Abstract
We investigated the relationship between a number of patient and management variables and mortality after surgery for fracture of the hip. Data relating to 18 817 patients were obtained from the Scottish Hip Fracture Audit database. We divided variables into two categories, depending on whether they were case-mix (age; gender; fracture type; pre-fracture residence; pre-fracture mobility and ASA scores) or management variables (time from fracture to surgery; time from admission to surgery; grade of surgical and anaesthetic staff undertaking the procedure and anaesthetic technique). Multivariate logistic regression analysis showed that all case-mix variables were strongly associated with post-operative mortality, even when controlling for the effects of the remaining variables. Inclusion of the management variables into the case-mix base regression model provided no significant improvement to the model. Patient case-mix variables have the most significant effect on post-operative mortality and unfortunately such variables cannot be modified by pre-operative medical interventions.

Abstract
BACKGROUND As a consequence of changes in population demographics, the extremely elderly represent one of the fastest growing groups in Western society. Previous studies have associated advanced age with increased mortality after hip fracture; however, this finding has not been consistent. METHODS The Scottish Hip Fracture Audit is a prospective, national, multicenter study that collects data on patients over the age of fifty years who are admitted to the hospital with a hip fracture. For the present study, we used data collected from twenty-two acute-care orthopaedic units between January 1998 and December 2005. The extremely elderly cohort consisted of 919 individuals with an age of ninety-five years or more. Case-mix variables and outcomes were compared with those for a modal control group of 15,461 individuals who were seventy-five to eighty-nine years of age. Outcome measures included thirty and 120-day mortality rates, the length of the hospital stay, the place of residence, and mobility. A multivariable logistic regression model was used to compare outcomes between groups while controlling for significant case-mix variables. RESULTS The extremely elderly presented with poorer indicators of health status as demonstrated by higher American Society of Anesthesiologists scores. In addition, this group was less likely to be independently mobile and more likely to be in institutional care at the time of the fracture (p < 0.001). Mortality at thirty and 120 days was higher in the extremely elderly even after adjusting for case-mix variables. The extremely elderly also were less likely to return home or to return to previous levels of mobility. CONCLUSIONS Although the extremely elderly exhibited a higher prevalence of prefracture indicators of poor outcome, statistical control for these case-mix variables showed further age-related deterioration in survival and outcomes after surgery for the treatment of a hip fracture.

Abstract
We report gender differences in the epidemiology and outcome after hip fracture from the Scottish Hip Fracture Audit, with data on admission and at 120 days follow-up from 22 orthopaedic units across the country between 1998 and 2005. Outcome measures included early mortality, length of hospital stay, 120-day residence and mobility. A multivariate logistic regression model compared outcomes between genders. The study comprised 25 649 patients of whom 5674 (22%) were men and 19 975 (78%) were women. The men were in poorer pre-operative health, despite being younger at presentation (mean 77 years (60 to 101) vs 81 years (50 to 106)). Pre-fracture residence and mobility were similar between genders. Multivariate analysis indicated that the men were less likely to return to their home or mobilise independently at the 120-day follow-up. Mortality at 30 and 120 days was higher for men, even after differences in case-mix variables between genders were considered.

Abstract
INTRODUCTION Hip fractures are responsible for excessive mortality, decreasing the 5-year survival rate by about 20%. From an economic perspective, they represent a major source of expense, with direct costs in hospitalization, rehabilitation, and institutionalization. The incidence rate sharply increases after the age of 70, but it can be reduced in women aged 70-80 years by therapeutic interventions. Recent analyses suggest that the most efficient strategy is to implement such interventions in women at the age of 70 years. As several guidelines recommend bone mineral density (BMD) screening of postmenopausal women with clinical risk factors, our objective was to assess the cost-effectiveness of two screening strategies applied to elderly women aged 70 years and older. METHODS A cost-effectiveness analysis was performed using decision-tree analysis and a Markov model. Two alternative strategies, one measuring BMD of all women, and one measuring BMD only of those having at least one risk factor, were compared with the reference strategy "no screening". Cost-effectiveness ratios were measured as cost per year gained without hip fracture. Most probabilities were based on data observed in EPIDOS, SEMOF and OFELY cohorts. RESULTS In this model, which is mostly based on observed data, the strategy "screen all" was more cost effective than "screen women at risk." For one woman screened at the age of 70 and followed for 10 years, the incremental (additional) cost-effectiveness ratio of these two strategies compared with the reference was 4,235 euros and 8,290 euros, respectively. CONCLUSION The results of this model, under the assumptions described in the paper, suggest that in women aged 70-80 years, screening all women with dual-energy X-ray absorptiometry (DXA) would be more effective than no screening or screening only women with at least one risk factor. Cost-effectiveness studies based on decision-analysis trees maybe useful tools for helping decision makers, and further models based on different assumptions should be performed to improve the level of evidence on cost-effectiveness ratios of the usual screening strategies for osteoporosis.

Abstract
Osteoporotic hip fractures increase dramatically with age and are responsible for considerable morbidity and mortality. Several treatments to prevent the occurrence of hip fracture have been validated in large randomized trials and the current challenge is to improve the identification of individuals at high risk of fracture who would benefit from therapeutic or preventive intervention. We have performed an exhaustive literature review on hip fracture predictors, focusing primarily on clinical risk factors, dual X-ray absorptiometry (DXA), quantitative ultrasound, and bone markers. This review is based on original articles and meta-analyses. We have selected studies that aim both to predict the risk of hip fracture and to discriminate individuals with or without fracture. We have included only postmenopausal women in our review. For studies involving both men and women, only results concerning women have been considered. Regarding clinical factors, only prospective studies have been taken into account. Predictive factors have been used as stand-alone tools to predict hip fracture or sequentially through successive selection processes or by combination into risk scores. There is still much debate as to whether or not the combination of these various parameters, as risk scores or as sequential or concurrent combinations, could help to better predict hip fracture. There are conflicting results on whether or not such combinations provide improvement over each method alone. Sequential combination of bone mineral density and ultrasound parameters might be cost-effective compared with DXA alone, because of fewer bone mineral density measurements. However, use of multiple techniques may increase costs. One problem that precludes comparison of most published studies is that they use either relative risk, or absolute risk, or sensitivity and specificity. The absolute risk of individuals given their risk factors and bone assessment results would be a more appropriate model for decision-making than relative risk. Currently, a group appointed by the World Health Organization and lead by Professor John Kanis is working on such a model. It will therefore be possible to further assess the best choice of threshold to optimize the number of women needed to screen for each country and each treatment.

Abstract
Despite the increase in numbers of the extreme elderly, little data is available regarding their outcome after surgery for fracture of the hip. We performed a prospective study of 50 patients aged 95 years and over who underwent this procedure. Outcome measures included morbidity, mortality, hospital stay, residential and walking status. Comparison was made with a control group of 200 consecutive patients aged less than 95 years who had a similar operation. The mortality at 28 and 120 days was higher (p = 0.005, p = 0.001) in the patients over 95 years. However, the one-year cumulative post-operative mortality was neither significantly different between the two groups (p = 0.229) nor from the standardised mortality rate for the age-matched population (p = 0.445). Predictors of mortality included the ASA grade, the number of comorbid medical conditions and active medical problems on admission. Patients over 95 were unlikely to recover their independence and at a mean follow-up of 29.3 months (12.1 to 48) 96% required permanent institutional care.

Abstract
UNLABELLED The number of the people with osteoporosis increases as the population ages. Increasing numbers of patients with osteoporotic fractures may have a serious economic impact on society and on the quality of life of the patient. We review some literature and provide expert opinion on the burden of osteoporosis. Awareness among clinicians and health care professionals on osteoporosis should be increased to overcome the burden of the disease. Although most of the osteoporotic fractures are treated by orthopaedic surgeons, many patients with these problems are not diagnosed appropriately and treated for probable osteoporosis. Appropriate diagnosis of the disease is essential to prevent osteoporotic fractures and related mortality and morbidity. Indirect costs and sociologic and psychological impact of fractures should be evaluated together with the direct costs of the disease. LEVEL OF EVIDENCE Economic and decision analysis, level V (expert opinion). See the Guidelines for Authors for a complete description of the levels of evidence.

Abstract
BACKGROUND Inadequate serum vitamin D is associated with secondary hyperparathyroidism, increased bone turnover, and bone loss, which increased fracture risk. Osteomalacia has also been observed in severe cases. Indeed, vitamin D and calcium are essential components of management strategies for the prevention and treatment of osteoporosis. Despite this, many people currently do not have adequate vitamin D levels. This problem has been documented in many studies around the world, regardless of age, health status, or latitude, and is especially common among older adults, who are also likely to have osteoporosis. Factors that contribute to low vitamin D include low exposure to sunlight, decreased synthesis in skin and reduced intestinal absorption related to aging, and limited dietary sources. Supplementation is the most effective means of correcting poor vitamin D nutrition. However, few patients with osteoporosis currently take sufficient vitamin D supplements. SCOPE This review article discusses the role of vitamin D in osteoporosis and skeletal health, and summarizes what is known about the high prevalence of inadequate serum vitamin D and recommendations for supplementation. CONCLUSION Greater awareness of the importance of vitamin D for skeletal health and more aggressive supplementation efforts are urgently needed to address this important public health problem.

Abstract
OBJECTIVE To determine gender-specific differences in prefracture status and postoperative outcome in elderly hip fracture patients who were ambulatory, community-dwelling, and cognitively intact prior to fracture. DESIGN Retrospective analysis of prospectively collected data. SETTING Urban orthopedic referral hospital. PATIENTS A total of 983 consecutive patients (206 males and 777 females) who sustained a nonpathologic hip fracture were followed for a minimum of 12 months. INTERVENTION Operative treatment of a proximal femur fracture. MAIN OUTCOME MEASUREMENTS Postoperative medical complications, place of discharge, 1-year mortality, and postoperative recovery of ambulation, basic activities of daily living, and instrumental activities of daily living. RESULTS Men were more likely to be married or living with someone else, and they were more dependent in instrumental activities of daily living than women prior to hip fracture. Furthermore, men were sicker as evidenced by a higher American Society of Anesthesiologists rating of preoperative risk. Postoperatively, men were more likely to sustain a medical complication and had a higher mortality at 1 year compared to women. There were no statistically significant gender differences in patient age, fracture type, prefracture level of help, ambulation, or dependence in basic activities of daily living, place of discharge, and postoperative recovery of ambulation as well as basic and instrumental activities of daily living. CONCLUSIONS Male gender was a risk factor for sustaining a postoperative complication as well as a higher mortality at 1 year post hip fracture.

Abstract
Postmenopausal osteoporosis (PMO) is a common disease that will become more prevalent in the future, with costly implications for public health. Prevention of the disease and its consequences, namely fractures, is therefore, important for both the individual and society. This review discusses: the goals of PMO prevention; the identification of women at risk, including the use of bone mineral density and bone turnover markers; the relevance in the prevention setting of various current guidelines for PMO management; recent data on therapeutic options for the treatment and prevention of PMO, in particular bisphosphonates, hormone replacement therapy and several other new pharmacological agents. It concludes that it is crucial for PMO prevention to start before disease onset and that, in the light of recent evidence, the existing guidelines need updating if they are to continue to be relevant.

Abstract
OBJECTIVE To assess the cost implications for a preventive treatment strategy for institutionalised elderly women with a combined 1200 mg/day calcium and 800 IU/day vitamin D(3) supplementation in seven European countries. DESIGN Retrospective cost effectiveness analysis based on a prospective placebo-controlled randomised clinical trial. DATA SOURCES Recently published cost studies in seven European countries. Clinical results from Decalyos, a 3-year placebo-controlled study in elderly institutionalised women. TRIALS Decalyos study, with 36 months follow-up of 3270 mobile elderly women living in 180 nursing homes, allocated to two groups. One group received 1200 mg/day elemental calcium in the form of tricalcium phosphate together with 800 IU/day (20 microg) of cholecalciferol (vitamin D(3)), the other placebo. RESULTS In the 36 months analysis of the Decalyos study, 138 hip fractures occurred in the group of 1176 women, receiving supplementation and 184 hip fractures in the placebo group of 1127 women. The mean duration of treatment was 625.4 days. Adjusted to 1000 women, 46 hip fractures were avoided by the calcium and vitamin D(3) supplementation. For all countries, the total costs in the placebo group were higher than in the group receiving supplementation, resulting in a net benefit of 79000-711000 per 1000 women. CONCLUSION This analysis suggests that the supplementation strategy is cost saving. The results may underestimate the net benefits, as this treatment has also shown to be effective in decreasing the incidence of other non-vertebral fractures in elderly institutionalised women.

Abstract
STUDY OBJECTIVE To determine whether men and women admitted to a university teaching hospital for a low-trauma hip fracture were diagnosed, evaluated, or treated for osteoporosis during admission or for up to 1 year after admission. DESIGN Retrospective chart review. SETTING University of Colorado Hospital, Denver, Colorado. PATIENTS One hundred eighteen patients admitted with a low-trauma hip fracture from January 1993-December 1998. MEASUREMENTS AND MAIN RESULTS Demographics, medical and social history, prescribed drugs, clinical outcomes, and information regarding the diagnosis, evaluation, and treatment of osteoporosis were abstracted from inpatient medical records for the index hip fracture. Similar data for the first year after the index hip fracture were abstracted from outpatient medical records of patients who had follow-up visits within the hospital system. Mean +/- SD age at the time of fracture was 70 +/- 15 years; 43 patients were men and 75 were women. Eighteen percent of patients had experienced a previous hip fracture, 4% had a history of vertebral fracture, and 6% reported a previous wrist fracture. The diagnosis of osteoporosis was noted in the charts of 14% of the patients at discharge and 26% of patients at follow-up. Only 4% of patients during hospitalization and 9% during follow-up received any evaluative tests for osteoporosis, including bone densitometry. Subsequent fractures occurred in 12.5% of patients. Documented treatment of osteoporosis was uncommon, with approximately 75% of patients receiving no therapy for osteoporosis on discharge or during follow-up. Women were more likely than men to receive a diagnosis of osteoporosis, bone mineral density testing, and osteoporosis drug therapy. CONCLUSION In patients with hip fractures, osteoporosis is commonly not diagnosed or treated appropriately

Abstract
OBJECTIVE To determine the mortality risk following hip fracture and identify factors predictive of increased mortality. DESIGN Retrospective review of prospectively collected data. SETTING Tertiary care orthopaedic hospital. BACKGROUND Approximately 250,000 hip fractures occur annually in the United States. The greatest mortality risk following hip fracture has been demonstrated to be within the first 6 months of fracture, and some studies report that the risk approaches expected mortality after 6 months. However, more recent studies have demonstrated that an increased risk of mortality may persist for several years postfracture. The purpose of this study was to assess the excess mortality associated with hip fracture at up to 2 years postinjury. METHODS All patients with a hip fracture who were admitted to our institution over a 10-year period were evaluated. Criteria for inclusion included: Caucasian, age 65 or older, previously ambulatory, and home dwelling. Patients were followed prospectively to determine the mortality risk associated with hip fracture over a 2-year follow-up period. Mortality was compared to a standardized population and standardized mortality ratios were calculated. RESULTS Eight hundred thirty-six patients met the inclusion criteria and were included. The mortality risk was highest within the first 3 months following fracture, with standardized mortality ratios approaching that of the control population by two years. Patients age 65-84 had higher mortality risk when compared with patients age > or =85. American Society of Anesthesiologists classification was predictive of increased mortality risk in younger patients, with these patients having triple the mortality risk when compared to the reference population at 2-year follow-up. More elderly patients had minimal excess mortality associated with hip fracture at 1- and 2-year follow-up, regardless of ASA classification. CONCLUSION The data demonstrate that hip fracture is not associated with significant excess mortality amongst patients older than age 85. Amongst younger patients, however, those with ASA classifications of 3 or 4 have significant excess mortality following hip fracture that persists up to 2 years after injury.

Abstract
BACKGROUND AND AIMS Many studies have identified specific demographic, social, health or life-style pre-operative indicators of long-term outcome among older hip fracture patients who underwent surgical treatment. The purpose of this study was to determine the predictive value of peri- and intra-operative factors, and more specifically of the pre-operative American Society of Anesthesiologists (ASA) score on functional outcome in these patients. METHODS A questionnaire designed to assess pre-fracture functional and health status was administered to surgically treated hip fracture patients. Post-fracture functional and health status was further ascertained by in-home interview one year after the operation. Among 140 consecutive eligible patients older than 65 years, 10 either refused subsequent interviews or could not be contacted; an additional 16 patients died during the year of follow-up, leaving 114 patients available for this study. RESULTS The average age of the patients was 82.4 years. Almost two-thirds of them suffered from severe systemic disease, whether or not incapacitating (ASA grades III-IV). Subjects classified in these categories presented more frequently with cardiovascular disorders, were more frequently disoriented, and already had some pre-fracture difficulty with ambulation. The mortality at one year was almost nine times higher in severely impaired patients (grades III-IV) than in healthy or mildly affected patients (grades I-II). Functional outcome and/or ambulatory ability assessed at one year did not reveal any statistically significant difference between the ASA I-II and III-IV groups. The most pronounced difference was noticed for the functional independence measured by the ADL score (p = 0.236). Better prognoses were consistently recorded for patients with an intracapsular fracture, for those who were operated within 24 hours, for those treated with a prosthesis as opposed to internal fixation, and for those whose operating time was less than 1 1/2 hours. CONCLUSIONS Although the ASA classification is a good predictor of long-term mortality, the findings of the present investigation do not conclusively associate ASA score with post-operative restoration of mobility and functional independence.

Abstract
Bone mass declines and the risk of fractures increases as people age, especially as women pass through the menopause. Hip fractures, the most serious outcome of osteoporosis, are becoming more frequent than before because the world's population is ageing and because the frequency of hip fractures is increasing by 1-3% per year in most areas of the world. Rates of hip fracture vary more widely from region to region than does the prevalence of vertebral fractures. Low bone density and previous fractures are risk factors for almost all types of fracture, but each type of fracture also has its own unique risk factors. Prevention of fractures with drugs could potentially be as expensive as medical treatment of fractures. Therefore, epidemiological research should be done and used to identify individuals at high-risk of disabling fractures, thereby allowing careful allocation of expensive treatments to individuals most in need.

Abstract
BACKGROUND Little empirical research has examined the multiple consequences of osteoporosis on quality of life. METHODS Health related quality of life (HRQL) was examined in relationship to incident fractures in 2009 postmenopausal women 50 years and older who were seen in consultation at our tertiary care, university teaching hospital-affiliated office and who were registered in the Canadian Database of Osteoporosis and Osteopenia (CANDOO) patients. Patients were divided into three study groups according to incident fracture status: vertebral fractures, non-vertebral fractures and no fractures. Baseline assessments of anthropometric data, medical history, therapeutic drug use, and prevalent fracture status were obtained from all participants. The disease-targeted mini-Osteoporosis Quality of Life Questionnaire (mini-OQLQ) was used to measure HRQL. RESULTS Multiple regression analyses revealed that subjects who had experienced an incident vertebral fracture had lower HRQL difference scores as compared with non-fractured participants in total score (-0.86; 95% confidence intervals (CI): -1.30, -0.43) and the symptoms (-0.76; 95% CI: -1.23, -0.30), physical functioning (-1.12; 95% CI: -1.57, -0.67), emotional functioning (-1.06; 95% CI: -1.44, -0.68), activities of daily living (-1.47; 95% CI: -1.97, -0.96), and leisure (-0.92; 95% CI: -1.37, -0.47) domains of the mini-OQLQ. Patients who experienced an incident non-vertebral fracture had lower HRQL difference scores as compared with non-fractured participants in total score (-0.47; 95% CI: -0.70, -0.25), and the symptoms (-0.25; 95% CI: -0.49, -0.01), physical functioning (-0.39; 95% CI: -0.65, -0.14), emotional functioning (-0.97; 95% CI: -1.20, -0.75) and the activities of daily living (-0.47; 95% CI: -0.73, -0.21) domains. CONCLUSION Quality of life decreased in patients who sustained incident vertebral and non-vertebral fractures.

Abstract
The purpose of this study was to clarify the survival rates and prognostic factors in elderly Japanese patients with hip fractures. This study investigated the outcome of 256 patients aged 60 years and older with surgically treated hip fractures. Information including age, gender, duration of hospitalization, place of residence before fracture and at discharge, and level of mobility before fracture and at discharge was obtained from patient records. The survival of the patients after discharge was determined by mail surveys supplemented with telephone inquiries.The observed survival rates were significantly lower than the expected survival rates p<0.001, by Mantel Haenszel test). The short-term mortality rates were 6% for six months and 12.7% for one year, which were lower than previously reported rates in Western countries. Significantly higher hazard ratios (HR) for mortality adjusted for age and gender were observed in patients who had lived in places other than their own home before fracture (HR=2.67 (1.63-4.3)). were discharged to places other than their own home (Nursing home HR=2.25 (1.24-4.1) or to a non-orthopedic unit (HR=5.95 (3.12-11.34), those requiring full-time assistance for mobility at discharge (HR=5.71 (3.59-9.01)), and those who had stayed in a hospital for fewer than 40 days (HR=2.20 (1.38-3.51)). After adjusting for the effects of all the potential prognostic factors, discharge to places other than their own home and the lowest level of mobility at discharge remained significant factors causing adverse effects on survival. Therefore, to improve the prognosis, patients should be allowed to recover to a level at which they can ambulate with some assistance, enabling them return to their own homes.

Abstract
The aim of non-pharmacological intervention for osteoporosis is to prevent, treat or alleviate the consequences of osteoporosis, the main one of which is fracture. Non-pharmacological interventions consist of a wide spectrum of treatment modalities to decrease pain, correct postural change, improve mobility, enable the patient to follow a normal social life and prevent (further) fracture. An exercise programme can increase bone mass in adolescents and adults, but in the elderly its main emphasis should be on improving muscle strength and balance in order to decrease the risk of falls. Physiotherapy is commonly prescribed to mobilize the patient after a fracture, to decrease muscle spasm and pain, and to improve balance and co-ordination. An orthesis or back support may be used to correct kyphosis and decrease pain. Medication for pain is often needed and should cover both acute severe pain following fracture and chronic pain caused by postural change. A hip fracture is the most severe consequence of osteoporosis. The risk of hip fracture can be decreased by pharmacological treatment to increase bone mass and bone strength. However, in the very elderly the occurrence of falling may be more important than the failure of bone strength. Hip protectors have recently become available and have been shown to decrease the risk of hip fracture after a fall. These shunt the energy from the trochanter away to the sides. Non-pharmacological approaches to treatment are often neglected in daily practice, the emphasis being instead on treatment with drugs that decrease bone resorption and thereby increase bone strength.

Abstract
This article reviews the impact of osteoporosis on quality of life. It defines specific impairments and suggests how best to minimize the impact of osteoporosis on patients' daily lives. Specific issues such as a spinal deformity, limitations on activities of daily living, pain, functionality, social impairment, self esteem, and depression also are addressed. Finally, a multidisciplinary team approach to osteoporosis is advocated.

Abstract
OBJECTIVE To compare posthospital rehabilitation resource utilization and self-care outcome of women with hip fracture discharged to three types of setting (home, inpatient rehabilitation, skilled nursing). DESIGN Prospective cohort study. Patient interviews in the hospital, 2 and 6 months after fracture, hospital record reviews. SETTING Two general community and two teaching hospitals. PATIENTS Consecutive sample of community-living women with hip fracture, aged 65 and over. Of 179 eligible, 130 patients enrolled and 123 completed study. INTERVENTIONS Prospective observational study. MAIN OUTCOME MEASURES Posthospital institutional days, cumulative sessions of physical and occupational therapy within 6 months after fracture, and 2- and 6-month Barthel Index. RESULTS For patients discharged to home, inpatient rehabilitation, and skilled nursing, respectively, mean posthospital institutional days were 1, 16, and 50; mean sessions of physical therapy were 15, 35, and 50; mean sessions of occupational therapy were 0, 11, and 16; mean 2-month Barthel Index was 93, 89, and 80; mean 6-month Barthel Index was 89, 88, and 86. Differences in posthospital institutional days and physical and occupational therapy sessions, but not 2- and 6-month Barthel Index, were statistically significant after controlling for patient characteristics. CONCLUSIONS Type of posthospital setting is associated with resource utilization, but not self-care outcome after hip fracture.

Abstract
The worldwide prevalence of hip fracture is increasing as the mean age of the population increases. Despite advances in anesthesia, nursing care, and surgical techniques, however, the outcome of treatment is often poor, and hip fractures remain a significant source of morbidity and mortality for the elderly population. For these patients, operative treatment is considered to be optimal and most cost-effective for displaced intracapsular fractures and all extracapsular fractures. Undisplaced intracapsular fractures can be treated with bed rest and 6-8 weeks' delay of weight bearing in the "younger" elderly (< or = 70 years). The timing of surgery remains controversial, and evidence that a delay in operating leads to increased morbidity is inconclusive. In general, early surgery is indicated in premorbidly fit patients, whereas surgery should be delayed if correctable comorbidities are present. Methods of intracapsular fracture repair very geographically and according to surgeon preference. Prospective, randomized, case-controlled studies are needed to compare repair methods, including internal fixation versus hemiarthroplasty for intracapsular fractures and use of uncemented versus cemented hemiarthroplasty protheses. Extracapsular fractures are usually repaired using a dynamic hip screw or other variant of sliding nail fixation. The mortality rate after hip fracture appears to vary in association with poorly controlled systemic disease (particularly if multiple comorbidities are present); cognitive disorders; operative intervention before stabilization if > or = 3 comorbidities are present; and, in the absence of prophylaxis, deep vein thrombosis; the associations between mortality and male sex, advanced age, and anesthetic type are less clear. The factors associated with the recovery of walking ability include young age, male sex, absence of dementia, absence of postoperative confusional state, and use of a walking aid before the fracture. Many determinants of outcome are independent of the level of care given and are dependent on prefracture status. To maximize rehabilitation potential, a multidisciplinary approach using skilled medical, nursing, and paramedical care appears to be optimal. Prospective case-controlled studies are required to demonstrate the long-term effectiveness of specialist rehabilitation units. In today's cost-cutting environment, caution must be taken to prevent short-term cost-saving measures from compromising long-term outcome for elderly hip fracture patients.

Abstract
OBJECTIVE To determine the one year mortality following hip fracture in an ambulatory, community dwelling, cognitively intact elderly population and to examine the role of specific type, number, and severity of associated medical comorbidities. DESIGN Prospective, consecutive. METHODS Six hundred twelve elderly who sustained a non-pathologic hip fracture were followed. RESULTS Twenty-four patients (4%) died during hospitalization; seventy-eight (12.7%) died within one year of fracture. The factors that were predictive of mortality, based on multivariate analysis, were patient age > 85 years, preinjury dependency in basic activities of daily living, a history of malignancy other than skin cancer, American Society of Anesthesiologists rating of operative risk 3 or 4, and the development of one or more in-hospital postoperative complications; all factors other than the development of an in-hospital complication were independent of treatment. CONCLUSION These results indicate that efforts at reducing one year mortality after hip fracture should be directed at the prevention of postoperative complications.

Abstract
OBJECTIVE Few studies have examined the time-dependent change in functional recovery along with the factors that affect the change among older hip fracture patients. The focus of this study is to examine the predictors of functional recovery in community-dwelling older people with subcapital fractures using longitudinal data analysis methods. DESIGN A 1-year prospective study. Information was obtained through structured interviews following surgery and at 2, 6, and 12 months after hospital discharge and from medical chart review. SETTING AND PATIENTS The sample consisted of 312 community-dwelling older adults, admitted to one of the seven Baltimore area hospitals with a subcapital fracture, who received either internal fixation or hemiarthroplasty. RESULTS The longitudinal data analysis using mixed-effects regression indicates that time and prefracture physical activities of daily living (PADL) had a significant association with PADL functional recovery over the course of 1 year. Among those 85 years and older, those who were disoriented after surgery had poorer PADL functional recovery over time than those who were not disoriented. Also, recovery in instrumental activities of daily living (IADL) was associated significantly with time, prefracture IADL function, unsteady gait prefracture, hospital length of stay, and discharge to an institution. The type of surgical procedure performed was not associated significantly with either PADL or IADL functional recovery. CONCLUSIONS The factors that are related to functional recovery in this study shed light on the complexity of the recovery process in hip fracture patients. The rate of recovery in postsurgical PADL and IADL function is not constant over time; postsurgical IADL function among disoriented patients (without dementia) continues to deteriorate over time compared with the nondisoriented group; this difference in trends of deterioration on IADL function is most profound in the oldest-old aged group, those 85 and older. The types of surgical procedure performed was not significantly associated with postsurgical functional recovery.

Abstract
Five hundred and sixteen community-dwelling, ambulatory, geriatric hip fracture patients who were independent prior to fracture were followed prospectively to determine which patients regained their prefracture independent living status at 3-, 6-, and 12-month follow-up. At 3-, 6-, and 12-month follow-up, 78, 77, and 76% of the patients, respectively, had regained their prefracture independent living status. Analysis was performed to determine which pre- and postinjury factors were predictive of a patient regaining prefracture independent living status at 3, 6, and 12 months after fracture. Patients who were younger than age 85, independent in activities of daily living prior to fracture, independent in ambulation at hospital discharge, and who had three or more medical comorbidities were more likely to regain their prefracture independent living status.
