Short- and long-term mortality in males and females with fragility hip fracture in Norway. A population-based study

Managing Mortality: Key Factors Influencing Hemiarthroplasty Outcomes in Geriatric Patients with Proximal Femur Fractures

Background and Objectives: Proximal femur fractures represent a significant health issue in the elderly, associated with high morbidity and mortality rates. This retrospective cohort study investigated factors influencing mortality (age, gender, infection, mobilization status, hospital stay length, surgical delay) in patients undergoing hemiarthroplasty for proximal femur fractures in a tertiary university hospital in Turkey. Materials and Methods: A retrospective analysis was conducted on 481 patients who underwent hemiarthroplasty at 19 Mayıs University hospital in Turkey between 2012 and 2022, with final follow-up data collected in 2022. Data collected included demographic information, the type of surgical approach, the duration of surgery, comorbidities, postoperative complications, and mobilization status at 1 and 6 months post-surgery. Statistical analyses were performed using the Mann-Whitney U test for age and surgery delay; the Kruskal-Wallis test for comparisons of mortality subgroups; the Chi-square test for categorical variables such as gender, fracture type, anesthesia type, and postoperative complications; and the Z test for post hoc analysis of categorical data. Results: The overall mortality rate at final follow-up was 56.1% over the entire study period (2012-2022), with a 6-month mortality rate of 21.8% and a 1-year mortality rate of 33.2%. Age and male gender were significant predictors of mortality. Infection rates were significantly associated with higher mortality within the first year. The study found no significant relationship between surgical approach, duration of surgery, or anesthesia type and mortality. However, increased length of hospital stay and delayed surgery correlated with higher mortality rates. Mobilization status significantly impacted survival, with immobilized patients demonstrating the highest mortality rates. Conclusions: Mortality following hemiarthroplasty for proximal femur fractures is influenced by various factors, including age, comorbidities, infection, and mobilization status. Implementing strategies for early surgery and mobilization while maintaining strict aseptic techniques could potentially reduce mortality rates in this high-risk population.

Exploring mortality risk factors and specific causes of death within 30 days after hip fracture hospitalization

This study examined the sex-specific mortality risk and causes of death soon after hip fracture in Taiwan. The objective of this study was to evaluate the 30-day mortality risk and cause of death in patients with hip fracture and identify its associated risk factors. We conducted a retrospective cohort study using data from the National Health Insurance Research Database in Taiwan from 2000 to 2015. This study included patients aged 50 years or older who were admitted to a hospital with a hip fracture diagnosis for the first time. Of 285,891 patients hospitalized for their first hip fracture, 8,505 (2.98%) died within 30 days. The mortality risk of hip fracture declined from 3.76% in 2000 to 2.92% in 2015. Circulatory system diseases like ischemic heart disease and cerebrovascular disease were the most common cause of death and accounted for 22% of deaths within 30 days after fracture. Accidents and unintentional injuries caused 18% of deaths, followed by malignant neoplasms in 10% of deaths. Multivariate Cox regression identified older age, male sex, higher Charlson Comorbidity Index (CCI), suburban or rural residence, and lower income as risk factors for hip fracture mortality. The 30-day mortality risk of hip fractures has decreased but remains correlated with male sex, older age, and comorbidities. Circulatory diseases were the main cause of death. Early identification and treatment by experienced clinicians may optimize outcomes, minimize complications, and reduce mortality risk in the 30 days following hip fracture.

Effect of different analgesic treatments on the pulmonary function in elderly hip fracture patients: A prospective study

BACKGROUND

To investigate the effect of different analgesic methods on lungs in elderly patients with hip fractures.

METHODS

A prospective study was conducted on 78 elderly hip fracture patients undergoing spinal anesthesia for surgery, where 3 analgesic methods were used: postoperative Patient-controlled intravenous analgesia pump (PCIA) (group I), pre and postoperative PCIA (group II), and preoperative fascia iliaca compartment block (FICB) + postoperative PCIA (group III). The following indicators were monitored at admission (T1), on the day of surgery before anesthesia (T2), and 7 days after surgery (T3): heart rate (HR), respiratory rate (RR), forced expiratory volume during the first second, arterial partial pressure of oxygen (PaO2) and carbon dioxide (PaCO2), C-reactive protein (CRP), and interleukin 6 (IL-6). Pulmonary complications such as pulmonary atelectasis and respiratory insufficiency were analyzed.

RESULTS

The HR, RR, forced expiratory volume during the first second, PaO2, PaCO2, IL-6, and CRP levels at T1 after fracture did not significantly differ among the 3 groups (P > .05). After different analgesic treatments post-admission, all indicators at T2 were significantly higher in group I than in groups II and III (P < .05), while there was no significant difference between groups II and III (P > .05). At T3, there were no significant differences in RR, HR, PaO2, PaCO2, and CRP levels among the groups (P > .05), but IL-6 levels at T3 were significantly higher in group I than in groups II and III (P < .05).

CONCLUSION

The use of effective pain relief during surgery can help protect the lung function of elderly patients with hip fractures. When using PCIA with FICB before surgery, respiratory performance may be better protected compared to using unsustained analgesia. This could be due to a decrease in the levels of inflammatory markers such as CRP and interleukin-6.

Geriatric nutritional risk index as the prognostic factor in older patients with fragility hip fractures

This study investigated the long-term survival and incidence of secondary fractures after fragility hip fractures. The 5-year survival rate was 62%, and the mortality risk was seen in patients with GNRI < 92. The 5-year incidence of secondary fracture was 22%, which was significantly higher in patients with a BMI < 20.

BACKGROUND

Malnutrition negatively influences the postoperative survival of patients with fragility hip fractures (FHFs); however, little is known about their association over the long term.

OBJECTIVE

This study evaluated the ability of the geriatric nutritional risk index (GNRI) as a risk factor for long-term mortality after FHFs.

METHODS

This study included 623 Japanese patients with FHFs over the age of 60 years. We prospectively collected data on admission and during hospitalization and assessed the patients' conditions after discharge through a questionnaire. We examined the long-term mortality and the incidence of secondary FHFs and assessed the prognostic factors.

RESULTS

The mean observation period was 4.0 years (range 0-7 years). The average age at the time of admission was 82 years (range 60-101 years). The overall survival after FHFs (1 year, 91%; 5 years, 62%) and the incidence of secondary FHFs were high (1 year, 4%; 5 years, 22%). The multivariate Cox proportional hazard analysis revealed the risk factors for mortality as older age (hazard ratio [HR] 1.04), male sex (HR 1.96), lower GNRI score (HR 0.96), comorbidities (malignancy, HR 2.51; ischemic heart disease, HR 2.24; revised Hasegawa dementia scale ≤ 20, HR 1.64), no use of active vitamin D3 on admission (HR 0.46), and a lower Barthel index (BI) (on admission, HR 1.00; at discharge, HR 0.99). The GNRI scores were divided into four risk categories: major risk (GNRI, < 82), moderate risk (82-91), low risk (92-98), and no risk (> 98). Patients at major and moderate risks of GNRI had a significantly lower overall survival rate (p < 0.001). Lower body mass index (BMI) was also identified as a prognostic factor for secondary FHFs (HR 0.88 [p = 0.004]).

CONCLUSIONS

We showed that older age, male sex, a lower GNRI score, comorbidities, and a lower BI are risk factors for mortality following FHFs. GNRI is a novel and simple predictor of long-term survival after FHFs.

Factors predictive of functional outcomes and quality of life in patients with fragility hip fracture: A retrospective cohort study

To determine the predictors of functional outcomes and quality of life (QoL) of patients who were surgically treated for fragility hip fracture. This was a retrospective cohort study performed in the 3 tertiary rehabilitation facilities. A total of 165 patients who had undergone surgery for fragility hip fracture were followed up to 6 months postoperatively. The factors expected to be related to the functional outcomes and QoL at 6 months post-surgery were as follows: baseline demographics, fracture site, operation type, fall characteristics including fall location and fall direction, comorbidities, and initial functional status. The following were comorbidities: hypertension, diabetes mellitus, dementia, cerebrovascular accident, and osteoporosis. Functional outcome and QoL measures were represented using the Koval grade, functional ambulatory category (FAC), Berg balance scale, 4-m walking speed test, the Korean version of Mini-Mental State Examination, EuroQol 5-dimension (EQ-5D) questionnaire, the Korean version of Modified Barthel Index, and the Korean version of instrumental activities of daily living (K-IADL). For all tests, each patient was assessed immediately after transfer and at 6 months post-surgery. Multivariable regression analyses adjusting for factors mentioned above were as follows. Old age led to a significantly less favorable outcome on FAC and K-IADL at 6 months. Intertrochanteric fracture had a significantly positive impact on Koval at 6 months compared to femur neck and intertrochanteric fractures. Total hip replacement arthroplasty and bipolar hemiarthroplasty had a significantly positive impact on EQ-5D and FAC at 6 months respectively compared to other operation types. Fall characteristics didn't reveal any significant impact on functional outcomes and QoL. Patients with hypertension and diabetes mellitus had a significantly negative outcome on EQ-5D and K-IADL respectively. Among initial assessments of function and QoL, initial 4-m walking speed test, Korean version of Mini-Mental State Examination, K-IADL, and Korean version of Modified Barthel Index were independent predictors of function and QoL at 6 months. This study confirmed that age, fracture site, operation type, comorbidities, and initial physical and cognitive function significantly influenced recovery of function and QoL at 6 months in patients with fragility hip fractures.

One-year mortality after hip fracture surgery: urban-rural differences in the Colombian Andes

To determine urban-rural differences influencing mortality in patients with hip fracture in Colombian Andes Mountains over a 1-year period.

PURPOSE

To identify the urban-rural differences of sociodemographic variables, fracture-related characteristics, and preoperative and postoperative clinical factors associated with 1-year mortality in patients over 60 years old who underwent hip fracture surgery in the Andes Mountains.

METHODS

A total of 126 patients with a fragility hip fracture during 2019-2020 were admitted to a tertiary care hospital. They were evaluated preoperatively and followed up until discharge. Those who survived were contacted by telephone at 1, 3, and 12 months. Univariate, bivariate, and Kaplan-Meier analyses with survival curves were performed. Relative risk was calculated with a 95% confidence interval.

RESULTS

A total of 32.5% of the patients died within 1 year after surgery, with a significant difference between those who resided in rural areas (43.1%) and those who resided in urban areas (23.5%) (RR 1.70; 95% CI, 1.03 to 2.80, p = 0.036). In the multivariate analysis, anemia (hemoglobin level ≤ 9.0 g/dL during hospitalization) (RR 6.61; 95% CI, 1.49-29.37, p = 0.003), a blood transfusion requirement (RR 1.47; 95% CI, 1.07 to 2.01, p = 0.015), the type of fracture (subtrochanteric fracture (RR = 4.9, 95% CI = 1.418-16.943, p = 0.005)), and postoperative acute decompensation of chronic disease (RR 1.60; 95% CI, 1.01 to 2.53, p = 0.043) were found to be independent predictive factors of 1-year mortality after surgery.

CONCLUSIONS

There was a difference in 1-year mortality between patients from rural and urban areas. More studies must be conducted to determine whether rurality behaves as an independent risk factor or is related to other variables, such as the burden of comorbidities and in-hospital complications.

Patient-specific factors affecting survival following hip fractures-a 14-year follow-up study in Finland

The mortality of elderly hip fracture patients is high. Eighty-five percent of all patients were followed until death. The three most protective factors for 1-year survival were ASA class; BMI; and age, and the four most protective factors for 14-year survival were age; BMI; ASA class; and subtrochanteric fracture type.

OBJECTIVE

Hip fractures are associated with increased mortality. The purpose of this study was to evaluate the protective preoperative factors regarding the survival of short-term (1 year) and long-term (14 years) follow-up in a hip fracture cohort in Finland.

METHODS

A total of 486 patients, operated on in 2005 and 2006, were retrospectively evaluated. Survival was analyzed using Bayesian multivariate analysis and relative survival with the life table method. All patients were followed for a minimum of 14 years.

RESULTS

We analyzed 330 women and 156 men, whose mean ages were 82.4 and 72.0 years, respectively. The overall mortality rate was 7% at 1 month, 22% at 12 months, and 87% at 14 years. Protective factors against mortality at 1 year were ASA class (1-3), BMI ≥ 20 kg/m², age < 85 years, alcohol involvement, Alzheimer's disease, no comorbidities, certain operative methods, and female sex. Factors promoting survival at 14 years were age < 75 years, BMI ≥ 20 kg/m², ASA class (1-2), subtrochanteric fracture, certain operative methods, alcohol involvement, and no comorbidities.

CONCLUSIONS

Protective factors for 1-year survival in order of importance were ASA class, BMI, and age, and, correspondingly, for 14-year survival, age, certain operative methods, BMI, and ASA class. The relative survival of hip fracture patients was lower than that of the general population.

Epidemiology of risk factors and estimating 10-year probability of osteoporotic fractures in the Russian Federation

In assessing the risk of fractures, an important role is played by risk factors (RFs), the prevalence of which must be known among residents with different types of settlement in order to plan preventive measures in risk groups for fractures. Prevalence RFs varied depending on constituent entities and the settlement type.

PURPOSE

To investigate the prevalence of osteoporotic fractures (OPF) RFs and estimate absolute risk (AR) of OPF among urban vs rural residents of the Russian Federation.

METHODS

In total, 13,391 Russian women and men 40-69 years old from 12 regions participated in the study. Groups of urban (n = 12,237) and rural (n = 1154) subjects were comparable in terms of their age. Participants were interviewed using a standard modular questionnaire. AR of OPF was calculated using the Russian FRAX model. Age-dependent diagnostic and therapeutic intervention thresholds (DIT, TIT) were employed to stratify AR of OPF.

RESULTS

Among the OPF RFs, the most common were as follows: previous OPF (16.3%), causes of secondary osteoporosis (20.8%), and current smoking (17.9%). The frequencies of previous OPF and alcohol abuse in rural men were higher than in urban male residents. Urban women, compared with rural females, were characterized by such more frequent RFs as smoking and glucocorticoids' intake. AR increased with age and prevailed in women, compared with men, regardless of their age, region of residence, and settlement type. According to TIT, the frequency of high AR of major OPF in the sample was 7.0%. According to DIT, high, medium, and low AR of major OPF was detected in 3.1%, 42.2%, and 54.7% of participants, respectively. Among urban women compared with rural females, high AR of major OPF was more often detected (p < 0.05), using TIT, whereas there was no such pattern for men. We discovered the territorial variability of RFs and OPF AR.

CONCLUSION

Prevalence of OPF RFs varied in Russia depending on age, gender, constituent entities, and the settlement type. Our data have demonstrated the typical age-gender causation pattern of OPF AR. Over 40% of participants required densitometry and fracture risk reclassification.

Relatively low and moderate pre-fracture serum 25-hydroxyvitamin D levels associated with the highest survival in elderly hip fracture patients in Finland: a minimum 3-year follow-up

The association between serum 25-hydroxyvitamin D level and post-fracture mortality indicates beneficial relatively high serum 25-hydroxyvitamin D concentrations. A 1-year cohort study on 245 hip fracture patients in Finland indicated the lowest 3-year mortality and highest survival among patients with serum 25-hydroxyvitamin D level of 50-74 nmol/L.

PURPOSE

To explore pre-fracture serum 25-hydroxyvitamin D level as a factor associated with post-fracture survival among a cohort of hip fracture patients in Finland.

METHODS

A prospectively collected cohort of hip fracture patients (n = 245, 70% women) from two hospitals was followed for 3.2 post-hip fracture years. Serum 25-hydroxyvitamin D was measured in admission to the hospital and classified: < 50, 50-74, 75-99, and ≥ 100 nmol/L. Survival was analyzed with a Bayesian multivariate model. Relative survival was explored with the life table method according to serum 25-hydroxyvitamin D. Mortality according to serum 25-hydroxyvitamin D level and to the hospital was calculated.

RESULTS

Mortality in the patients with serum 25-hydroxyvitamin D level of 50-74 nmol/L was significantly lower than in all other patients together at every post-fracture year. The most important factors for survival were age under 85 years; living in an actual/private home; serum 25-hydroxyvitamin D level of 50-74 nmol/L, followed by 75-99 nmol/L; ASA classes 1-2 and 3; and female sex. The mean age of patients with serum 25-hydroxyvitamin D level of 50-99 nmol/L was significantly higher than in other levels. Relative survival was highest in men, women, and patients in hospital B with serum 25-hydroxyvitamin D level of 50-74 nmol.

CONCLUSION

The highest 3-year survival and the lowest mortality in this cohort appeared in patients with pre-fracture serum 25-hydroxyvitamin D level of 50-74 nmol/L. This result differs from similar studies and is lower than the recommended level of 25-hydroxyvitamin D among hip fracture patients. The results should be examined in future research with larger data.

Simple Excel and ICD-10 based dataset calculator for the Charlson and Elixhauser comorbidity indices

Background

The Charlson and Elixhauser Comorbidity Indices are the most widely used comorbidity assessment methods in medical research. Both methods are adapted for use with the International Classification of Diseases, which 10th revision (ICD-10) is used by over a hundred countries in the world. Available Charlson and Elixhauser Comorbidity Index calculating methods are limited to a few applications with command-line user interfaces, all requiring specific programming language skills. This study aims to use Microsoft Excel to develop a non-programming and ICD-10 based dataset calculator for Charlson and Elixhauser Comorbidity Index and to validate its results with R- and SAS-based methods.

Methods

The Excel-based dataset calculator was developed using the program’s formulae, ICD-10 coding algorithms, and different weights of the Charlson and Elixhauser Comorbidity Index. Real, population-wide, nine-year spanning, index hip fracture data from the Estonian Health Insurance Fund was used for validating the calculator. The Excel-based calculator’s output values and processing speed were compared to R- and SAS-based methods.

Results

A total of 11,491 hip fracture patients’ comorbidities were used for validating the Excel-based calculator. The Excel-based calculator’s results were consistent, revealing no discrepancies, with R- and SAS-based methods while comparing 192,690 and 353,265 output values of Charlson and Elixhauser Comorbidity Index, respectively. The Excel-based calculator’s processing speed was slower but differing only from a few seconds up to four minutes with datasets including 6250–200,000 patients.

Conclusions

This study proposes a novel, validated, and non-programming-based method for calculating Charlson and Elixhauser Comorbidity Index scores. As the comorbidity calculations can be conducted in Microsoft Excel’s simple graphical point-and-click interface, the new method lowers the threshold for calculating these two widely used indices.

Effect of chronic kidney disease on outcomes following proximal humerus fragility fracture surgery in diabetic patients: A nationwide population-based cohort study

BACKGROUND

The proximal humerus fracture (PHF) is the third most common fragility fracture. Diabetes mellitus (DM) and chronic kidney disease (CKD) are both risks for fragility fractures; however, the interplay of DM and CKD makes treatment outcomes unpredictable. This study aimed to investigate and compare early and late outcomes following proximal humerus fracture fixation surgery in diabetic patients with different renal function conditions.

METHODS

DM patients receiving PHF fixation surgery during 1998-2013 were recruited from Taiwan's National Health Insurance Research Database. According to their renal function, patients were divided into three study groups: non-chronic kidney disease (CKD), non-dialysis CKD, and dialysis. Outcomes of interest were early and late perioperative outcomes. Early outcomes included in-hospital newly-onset morbidities. Late outcomes included infection, revision, readmission, and all-cause mortality.

RESULTS

This study included a total of 10,850 diabetic patients: 2152 had CKD (non-dialysis CKD group), 196 underwent permanent dialysis (dialysis group), and the remaining 8502 did not have CKD (non-CKD group). During a mean follow-up of 5.56 years, the dialysis group showed the highest risk of overall infection, all-cause revision, readmission, and mortality compared to the non-dialysis CKD group and non-CKD group. Furthermore, subgroup analysis showed that CKD patients had a higher risk of surgical infection following PHF surgery than non-CKD patients in cases with a traffic accident or fewer comorbidities (Charlson Comorbidity Index, CCI <3) (P for interaction: 0.086 and 0.096, respectively). Also, CKD patients had an even higher mortality risk after PHF surgery than non-CKD patients, in females, those living in higher urbanization areas, or with more comorbidities (CCI ≥3) (P for interaction: 0.011, 0.057, and 0.069, respectively).

CONCLUSION

CKD was associated with elevated risks for infection, revision, readmission, and mortality after PHF fixation surgery in diabetic patients. These findings should be taken into consideration when caring for diabetic patients.

Nonoperative hip fracture management practices and patient survival compared to surgical care: an analysis of Estonian population-wide data

A notable proportion of hip fracture patients receive nonoperative management, but such practice is seldom analysed. Although highly variable reasons underpin hip fracture nonoperative management, none of these practices conclusively outweigh the superiority of operative management. Nonoperative management should be only considered when surgery is not an option.

PURPOSE

Reasons underpinning hip fracture (HF) nonoperative management (NOM) are seldom analysed. This study aims to identify the reasons behind NOM and assess the accuracy of these decisions using these patients' survival compared with those treated with operative management (OM).

METHODS

This is a retrospective cohort study based on population-wide administrative health data, including patients aged ≥ 50 with an index HF diagnosis between January 2009 and September 2017. NOM patients were subgrouped according to their expected prognoses, and their survival up to 36 months was compared with those treated surgically.

RESULTS

From a total of 11,210 included patients, 6.8% (766) received NOM. Varying reasons lead to NOM, dividing them further into five distinct subgroups: (I) 46% NOM decision due to poor expected prognosis with OM; (II) 29% NOM decision due to poor expected prognosis for mixed reasons; (III) 15% NOM decision due to good expected prognosis with NOM; (IV) 8.0% NOM decision due to patient's refusal of OM; and (V) 1.3% NOM decision due to occult HF. Only poor prognosis and patients who refused OM (I, II, IV) had worse survival than OM patients. However, a relatively high proportion of the poor prognosis patients survived 1 year (29%).

CONCLUSION

Although there was high variability in reasons underpinning HF NOM, none of these practices conclusively outweigh OM's superiority. NOM should be considered with utmost care and only for patients for whom OM is out of the question - well-defined medical unfitness or carefully considered refusal by understanding the increased mortality risk.

Effect of heart failure and malnutrition, alone and in combination, on rehabilitation effectiveness in patients with hip fracture

BACKGROUND & AIMS

Heart failure and malnutrition are known to each negatively affect a patient's ability to improve their activities of daily living (ADL) through rehabilitation. Here, we investigated whether the negative effects of malnutrition and heart failure on ADL are additive in patients after hip fracture.

METHODS

This retrospective observational cohort study included 155 patients with hip fracture admitted to convalescent rehabilitation wards. Nutritional status was measured with the Geriatric Nutritional Risk Index (GNRI). Heart failure was assessed using plasma B-type natriuretic peptide (BNP) levels. Based on their GNRIs and BNP levels, patients were classified into four groups: a high GNRI (≥92)-low BNP (<100 pg/ml) group (n = 54); high GNRI-high BNP (≥100 pg/ml) group (n = 7); low GNRI (<92)-low BNP group (n = 67); and low GNRI-high BNP group (n = 27). The main outcome was rehabilitation effectiveness (REs). To confirm above hypothesis, heart failure was also assessed by American College of Cardiology/American Heart Association (ACC/AHA) stage classification, whereas nutrition was assessed by Mini Nutritional Assessment Short Form (MNA-SF), either.

RESULTS

REs in the high GNRI-low BNP group, high GNRI-high BNP group, low GNRI-low BNP group, and low GNRI-high BNP group were 64.8 ± 22.6%, 36.0 ± 22.0%, 40.6 ± 23.6% and 28.5 ± 25.9%, respectively. REs was higher in the high GNRI-low BNP group than in other three groups, and REs in the low GNRI-low BNP group was higher than in the low GNRI-high BNP group. When we evaluated heart failure by ACC/AHA stage classification instead of BNP, or evaluated nutrition by MNA-SF instead of GNRI, the similar results were demonstrated. Multiple linear regression analyses revealed that age (p < 0.01), handgrip strength (p < 0.01), GNRI (p < 0.05), and BNP (p < 0.01) were significantly associated with REs.

CONCLUSIONS

These results suggest that malnutrition and heart failure are independently associated with REs and that they have an additive negative effect on improvement of ADL in elderly patients with hip fractures.

Hip Fracture Leads to Transitory Immune Imprint in Older Patients

Background: Hip fracture (HF) is common in the geriatric population and is associated with a poor vital and functional prognosis which could be impacted by immunological changes. The objective here is to decipher immune changes occurring in the 1st days following HF and determine how phenotype, function, and regulation of innate and adaptive compartments adapt during acute stress event.

Methods: We included HF patients, aged over 75 years. For each patient, blood samples were taken at five different timepoints: four in the perioperative period (day 0 to hospital discharge) and one at long term (6–12 months). Phenotypical and functional analysis were performed longitudinally on fresh blood or cryopreserved PBMCs. Clinical data were prospectively collected.

Results: One-hundred HF patients and 60 age-matched controls were included. Innate compartment exhibits pro-inflammatory phenotypes (hyperleukocytosis, increase of CD14+ CD16+ proportion and CCR2 expression), maintaining its ability to produce pro-inflammatory cytokines. Adaptive compartment extends toward a transitory immunosuppressive profile (leucopenia) associated with an active T-cell proliferation. Furthermore, increases of LAG-3 and PD-1 and a decrease of 2-B4 expression are observed on T-cells, reinforcing their transitory suppressive status. Of note, these immune changes are transitory and sequential but may participate to a regulation loop necessary for homeostatic immune control at long term.

Conclusion: HF is associated with several transitory immunological changes including pro-inflammatory phenotype in innate compartment and immunosuppressive profile in adaptive compartment. A comprehensive assessment of immune mechanisms implicated in the patient's prognosis after HF could pave the way to develop new immune therapeutics strategies.

C-Reactive Protein to Albumin Ratio May Predict Mortality for Elderly Population Who Undergo Hemiarthroplasty Due to Hip Fracture

BACKGROUND

Although the relationship of preoperative C-reactive protein (CRP) and albumin levels to mortality in elderly patients who have undergone surgery due to hip fracture has been previously investigated, the CRP to albumin ratio (CAR) has not been investigated. This study aimed to investigate the relationship between preoperative CAR and mortality.

METHODS

A total of 254 patients (mean age, 78.74 years) were retrospectively analyzed using the following data: age, gender, fracture type, American Society of Anesthesiologists (ASA) score, type of anesthesia, time between fracture and surgery, time between fracture and discharge, length of hospital stay, preexisting comorbidities, preoperative CRP and albumin levels, and mortality. The serum CRP level was divided by the serum albumin level to calculate the preoperative CAR. Multivariate logistic regression was used to evaluate the association between risk factors and 1-year mortality.

RESULTS

One-year mortality was 22.8% (58 patients). Age >85 years, male gender, ASA score ≥3, presence of ≥3 comorbidities, and CAR ≥2.49 were identified as mortality risk factors in the univariate analysis. The following factors were included in the binary logistic regression analysis to determine the major predictors of 1-year mortality: ASA score ≥3, presence of ≥3 comorbidities, and CAR ≥2.49.

CONCLUSION

Detection of CAR above 2.49 is a strong indicator for 1-year mortality in patients operated due to hip fracture in the elderly population. ASA score ≥3 and presence of ≥3 comorbid diseases were also related to mortality.

Risk factors for mortality and survival rates in elderly patients undergoing hemiarthroplasty for hip fracture

OBJECTIVE

The aim of this study was to analyze the relationship between mortality and possible risk factors in elderly patients surgically treated with hemiarthroplasty for hip fracture and to determine mortality rates and yearly survival outcome in a selected cohort.

METHODS

A total of 92 patients (51 men (55.4%) and 41 women (44.6%); mean age: 76.47 years) who underwent hemiarthroplasty for hip fracture were included into the study. The following data associated with risk factors were recorded for 92 patients: age, gender, pre-fracture activities of daily living (ADL), type of fracture, American Society of Anesthesiologists (ASA) score, therapeutic procedure, type of anesthesia, length of time after fracture until operation, postoperative mobility, and duration of hospitalization. A multivariate logistic regression test was used to evaluate the correlation between the risk factors and first- and second-year mortality rates. Third-year mortality rate after surgery was analyzed and compared with the general mortality rate in a similar population of the same age group living in the same city.

RESULTS

The mortality rate was 18.5% (17 patients) after the first-year follow-up and 25% (23 patients) after the second year. The mortality risk after hip fracture was found to be 11.7 times greater than the similar age group population in the third year. In addition, there was a significant relationship between a low (dependent) preoperative ADL score, advanced age (>80 years), male gender, high ASA score and poor ability to walk (unable to walk), and first- and second-year mortalities (p<0.05). However, no significant relationship was found between fracture type, fracture side, anesthesia type, time from fracture to surgery, or duration of hospitalization and mortality (p>0.05).

CONCLUSION

Advanced age, male gender, a high ASA score, a dependent preoperative ADL score, and a postoperative inability to walk were determined to be the most important risk factors affecting mortality in elderly patients with hip fracture. The mortality risk was 11.7 times greater than that of a population with similar characteristics.

Impact of osteoporotic fracture type and subsequent fracture on mortality: the Tromsø Study

Less is known about the impact of non-hip non-vertebral fractures (NHNV) on early death. This study demonstrated increased risk of dying following hip and NHNV fractures which was further increased by a subsequent fracture. This highlights the importance of early intervention to prevent both initial and subsequent fractures and improve survival.

INTRODUCTION

Osteoporotic fractures are a major health concern. Limited evidence exists on their impact on mortality in ageing populations. This study examined the contribution of initial fracture type and subsequent fracture on mortality in a Norwegian population that has one of the highest rates of fractures.

METHODS

The Tromsø Study is a prospective population-based cohort in Norway. Women and men aged 50+ years were followed from 1994 to 2010. All incident hip and non-hip non-vertebral (NHNV) fractures were registered. NHNV fractures were classified as either proximal or distal. Information on self-reported co-morbidities, lifestyle factors, general health and education level was collected. Multivariable Cox models were used to quantify mortality risk with incident and subsequent fractures analysed as time-dependent variables.

RESULTS

Of 5214 women and 4620 men, 1549 (30%) and 504 (11%) sustained a fracture, followed by 589 (38%) and 254 (51%) deaths over 10,523 and 2821 person-years, respectively. There were 403 (26%) subsequent fractures in women and 68 (13%) in men. Hip fracture was associated with a two-fold increase in mortality risk (HR 2.05, 95% CI 1.73-2.42 in women and 2.49, 95% CI 2.00-3.11 in men). Proximal NHNV fractures were associated with 49% and 81% increased mortality risk in women and men (HR 1.49, 95% CI 1.21-1.84 and 1.81, 95% CI 1.37-2.41), respectively. Distal NHNV fractures were not associated with mortality. Subsequent fracture was associated with 89% and 77% increased mortality risk in women and men (HR 1.89, 95% CI 1.52-2.35 and 1.77, 95% CI 1.16-2.71), respectively.

CONCLUSION

Hip, proximal NHNV and subsequent fractures were significantly associated with increased mortality risk in the elderly, highlighting the importance of early intervention.

Urban-Rural Differences in Hip Fracture Mortality: A Nationwide NOREPOS Study

Higher hip fracture incidence in urban than in rural areas has been demonstrated, but urban–rural differences in posthip fracture mortality have been less investigated, and the results are disparate. Hence, the aims of the present register‐based cohort study were to examine possible urban–rural differences in short‐ and long‐term mortality in Norwegian hip fracture patients and their potential associations with sociodemographic variables, and to investigate possible urban–rural differences in excess mortality in hip fracture patients compared with the general population. Data were provided from the NOREPOS hip fracture database, the 2001 Population and Housing Census, and the National Registry. The urbanization degree in each municipality was determined by the proportion of inhabitants living in densely populated areas (rural: <1/3, semirural: 1/3 to 2/3, and urban: >2/3). Age‐adjusted mortality rates and standardized mortality ratios were calculated for hip fracture patients living in rural, semirural, and urban municipalities. A flexible parametric model was used to estimate age‐adjusted average and time‐varying HRs by category of urbanization with the rural category as reference. Among 96,693 hip fracture patients, urban residents had higher mortality than their rural‐dwelling counterparts. The HR of mortality in urban compared with rural areas peaked during the first 1 to 2 years postfracture with a maximum HR of 1.20 (95% CI, 1.10 to 1.30) in men and 1.15 (95% CI, 1.08 to 1.21) in women. The differences were significant during approximately 5 years after fracture. Adjusting for sociodemographic variables did not substantially change the results. However, absolute 30‐day mortality was not significantly different between urban and rural residents, suggesting that health‐care quality immediately postfracture does not vary by urbanization. The novel findings of a higher long‐term mortality in urban hip fracture patients might reflect disparities in health status or lifestyle, differences in posthip fracture health care or rehabilitation, or a combination of several factors. © 2019 The Authors.

A novel quantitative method for estimating bone mineral density using B-mode ultrasound and radiofrequency signals-a pilot study on patients with rheumatoid arthritis

The objective of the present study was to evaluate whether an innovative quantitative ultrasound (QUS) technique, Radiofrequency Echographic Multi Spectromety, which combines B-mode ultrasound and radiofrequency signals, is reliable in typical Romanian patients compared to previous results obtained using dual-energy X-ray absorptiometry (DXA). The study prospectively included previously unscreened post-menopausal females with rheumatoid arthritis (RA) and age-matched healthy controls. Bone mineral density (BMD) measurements were performed with an EchoS machine (Echolight®), which combines B-mode ultrasound and radiofrequency signals. The study included 106 RA patients, with a median disease duration of 3.2 (0.5-22) years and 119 controls. RA patients had a significantly lower body weight, body mass index (BMI) and basal metabolic rate (BMR) than the controls, while the prevalence of obesity and body fat differed insignificantly. RA patients had a significantly lower spine and hip BMD, higher fracture risk and higher prevalence of osteoporosis. Compared to RA patients without osteoporosis, those with osteoporosis were significantly older and had a longer menopause duration, but they had a significantly lower BMI, body fat, BMR and prevalence of obesity. Among the controls and RA patients, the median spine and hip BMD became significantly higher as the BMI increased from underweight to obesity. In conclusion, osteoporosis is prevalent among RA patients, as a part of a complex transformation of body mass composition, involving BMI and fat mass. The novel QUS scanning technique was able to replicate the results of the established DXA measurement of BMD and is potentially suitable for screening wide populations for osteoporosis.

Estonian hip fracture data from 2009 to 2017: high rates of non-operative management and high 1-year mortality

Background and purpose - There are no national guidelines for treatment of hip fractures in Estonia and no studies on management. We assessed treatment methods and mortality rates for hip fracture patients in Estonia. Patients and methods - We studied a population-based retrospective cohort using validated data from the Estonian Health Insurance Fund's database. The cohort included patients aged 50 and over with an index hip fracture diagnosis between January 1, 2009 and September 30, 2017. The study generated descriptive statistics of hip fracture management methods and calculated in-hospital, 1-, 3, 6-, and 12-month unadjusted all-cause mortality rates. [CrossRef] Results - 91% (number of hips: 11,628/12,731) of the original data were included after data validation. Median patient age was 81 years, 83 years for women and 74 years for men. 28% were men. Treatment methods were: total hip arthroplasty 7%; hemiarthroplasty 25%; screws 6%; sliding hip screw 25%; intramedullary nail 27%; and nonoperative management 10%. Unadjusted all-cause mortality rates for in-hospital, 1, 3, 6, and 12 months were: 3%, 9%, 18%, 24%, and 31% respectively. The 12-month mortality rate for nonoperative management was 58%. [CrossRef] Interpretation - High rates of nonoperative management and overall high 1-year mortality rates after an index hip fracture indicate the need to review exclusion criteria for surgery and subacute care in Estonia.

C-reactive protein for early detection of postoperative systemic infections in intertrochanteric femoral fractures

BACKGROUND

This retrospective cohort study investigated perioperative C-reactive protein (CRP) value for early detection of postoperative systemic infective complications in elderly patients with intertrochanteric femoral fracture.

METHODS

A total of 250 patients aged ≥65 years, with intertrochanteric femoral fractures that were surgically treated between January 2011 and December 2015 were included. CRP value was measured preoperatively and on postoperative day (POD) 3, 5, and 10, and analyzed with regard to postoperative systemic infections, delirium, and death within 1 year. The patients were divided into two groups according to postoperative systemic infection, and perioperative CRP responses between the two groups were comparedusing t-test (or Man-Whitney test where appropriate). The receiver operator characteristic (ROC) curves of CRP value were used to determine the best-supported cut-off values for identifying postoperative systemic infections. Systemic infections were reclassified as pulmonary and extra-pulmonary infections.

RESULTS

The mean CRP values preoperatively and on POD 3, 5, and 10 were 2.82, 10.10, 3.74, and 1.89 mg/dL, respectively. Postoperative systemic infections, delirium, and death within 1 year were noted in 35 (14.0%), 30 (12.0%), and 45 (18.0%) patients, respectively. The CRP value in patients with postoperative systemic infections significantly elevated on POD 5 and 10 (p < 0.001, p < 0.001), and cut-off values were 4.71 and 1.59 mg/dL on POD 5 and 10, respectively. Postoperative delirium and death within 1 year were observed more often in the group with postoperative systemic infections (p = 0.003, p = 0.014). Although preoperatively elevated CRP values did not influence the postoperative CRP responses, they were significantly associated with delirium (p = 0.015).

CONCLUSIONS

The CRP value on POD 5 is the earliest predictor of postoperative systemic infections in elderly patients with intertrochanteric femoral fractures that are managed surgically. Moreover, when the CRP value on POD 5 is >4.71 mg/dL, the possibility of postoperative systemic infections should be considered.

Epidemiology of distal radius fracture in Akershus, Norway, in 2010-2011

BACKGROUND

Several studies published over the last decade indicate an increased incidence of distal radius fractures (DRF). With Norway having one of the highest reported incidence of DRFs, we conducted a study to assess the epidemiology of DRFs and its treatment in the catchment area of Akershus University Hospital (AHUS).

METHODS

Patients 16 years or older who presented to AHUS with an acute DRF during the years 2010 and 2011 were prospectively recorded and classified according to the AO fracture classification system. The mechanism of injury and treatment modality were noted.

RESULTS

Overall, 1565 patients with an acute DRF presented to the institution in 2010-2011, of which 1134 (72%) were women. The overall annual incidence was 19.7 per 10,000 inhabitants 16 years or older. Women had an exponential increase in incidence after the age of 50, though the incidence for both genders peaked after the age of 80 years. There was an even distribution between extra- and intra-articular fractures. Falling while walking outside was the most common mechanism of injury. Of the 1565 registered, 418 (26.7%) patients underwent surgery, with a volar locking plate being the preferred surgical option in 77% of the cases.

CONCLUSION

The overall incidence of distal radius fractures was lower in our study than earlier reports from Norway. Postmenopausal women had a higher risk of fracture than the other groups, and low-energy injuries were most dominant. 26.7% were treated operatively, which is higher than earlier reports, and might reflect an increasing preference for surgical treatment.

Diagnostic strategy for elderly patients with isolated greater trochanter fractures on plain radiographs

Background

Isolated greater trochanter (GT) fractures are relatively rare and few studies have assessed the appropriate diagnostic and therapeutic strategies for these fractures. When initial plain radiographs show an isolated GT fracture, underestimation of occult intertrochanteric extension may result in displacement of a previously non-displaced fracture. This study examined the clinical results and value of different diagnostic strategies in elderly patients with isolated GT fractures on plain radiographs.

Methods

Between January 2010 and January 2015, 30 patients with initial plain radiographs showing isolated GT fractures were examined using MRI, bone scanning and/or CT for suspected occult intertrochanteric extension. We assessed the sensitivity, specificity, and positive and negative predictive value of each test. In addition, we noted the location of the fracture or soft-tissue injury on MRI in addition to treatment results.

Results

All 30 patients had osteoporosis and fractures caused by minor trauma. MRI revealed isolated GT fractures in nine patients and occult intertrochanteric fractures in 21 patients. Using the MRI-based diagnosis as a reference, the results showed that plain radiographs, bone scans, and CT scans can be used for supplementary examination but they are not appropriate as confirmatory tests for these fractures. However, in patients with both isolated GT fractures seen on plain radiographs and increased uptake in only the GT area on bone scans, MRI revealed isolated GT fractures. The fractures were treated surgically in 20 patients and conservatively in 10 patients with satisfactory clinical results.

Conclusions

We confirmed that MRI-based examination is useful in all symptomatic elderly patients whose plain radiographic findings reveal isolated GT fractures. However, we suggest that there is a need to establish a diagnostic strategy through increased understanding of the available diagnostic methods. We believe that surgical treatment should be considered in patients with occult intertrochanteric fractures that are detected on MRI.

Cortical Thickness Index of the Proximal Femur: A Radiographic Parameter for Preliminary Assessment of Bone Mineral Density and Osteoporosis Status in the Age 50 Years and Over Population

BACKGROUND

Bone mineral density (BMD) is the indicator of bone quality in at-risk individuals. Along with the fracture risk assessment tool (FRAX), a quick assessment of BMD from routine radiographs may be useful in the case of lacking X-ray absorptiometry data. This study aimed to investigate the correlation of cortical thickness index (CTI) and canal flare index (CFI) with BMD and FRAX and to evaluate their ability to predict femoral neck BMD (nBMD) and FRAX in the general elderly population.

METHODS

A total of 560 volunteers (age ≥ 50 years) who underwent hip-spine X-ray, BMD scanning and FRAX calculation were retrospectively reviewed. CTI and CFI were measured on anteroposterior radiographs and analyzed for their correlation with BMD and FRAX and for their ability to predict nBMD. The ability of CTI to predict osteoporosis status (OPS) and fracture risk status (FRS) was also investigated and the threshold values were calculated. All the analyses were performed separately on male and female subjects.

RESULTS

Significant differences in CTI, CFI, nBMD and FRAX between males and females were observed. CTI and CFI demonstrated significant positive correlation with nBMD and FRAX (all p < 0.001) in both males and females. CTI, height, and weight significantly predicted nBMD. CTI statistically predicted OPS and FRS, and the values of 0.56 and 0.62 were computed as CTI thresholds for males and females, respectively.

CONCLUSIONS

CTI was significantly correlated with nBMD and it predicted nBMD at good prediction levels. Therefore, CTI may be used as a supportive tool in the assessment of OPS and FRS besides BMD and FRAX in clinical practice.

Morbidity and mortality after fragility hip fracture in a Saudi Arabian population: Report from a single center

Objective

To determine the functional morbidity and mortality after fragility hip fracture and compare the mortality with three other common diseases.

Methods

Data were collected from patients admitted to King Fahd Hospital of the University, AlKhobar from January 2010 to December 2014. Demographic data included the preoperative American Society of Anesthesiologists (ASA) score as assessed by the anesthetist and the type of surgery. Personal and telephone interviews were performed, and data were entered into a database and analyzed.

Results

We identified 203 patients with fragility proximal femoral fractures, and the data of 189 patients (109 male, 80 female; average age, 66.90 ± 13.43 years) were available for analysis. The overall mortality rate was 26.98% (51 patients). The mortality rate was significantly higher among patients with an ASA score of 4 (36.36%) than 1 (20.45%). With respect to morbidity, only 48.23% of patients were able to return to their pre-fracture status; 32.35% of those who required assisted walking and 83.4% of those who required a wheelchair became bedridden.

Conclusions

Our data demonstrate that patients with fragility hip fractures have high morbidity and a mortality rate approaching 30%. Age and the ASA score significantly influence this high mortality rate.

A multidisciplinary approach to improve the quality of care for patients with fragility fractures

BACKGROUND

Fragility fractures have become a worldwide epidemic associated with significant morbidity and mortality. As the world population ages, the number of patients that experience these fractures is also expected to rise. A multidisciplinary team was assembled that was coordinated by the Acute Inpatient Medical Service and included orthopedic surgeons, geriatricians, anesthesiologists, cardiologists, nurses, trauma surgeons, emergency medicine physicians, physiatrists, and physical therapists. This team was formed with the expectation that geriatric fragility fracture complications, specifically hip fractures, could be reduced by identifying and implementing best practices using guidelines from the American Academy of Orthopedic Surgery and those from the International Geriatric Fracture Society.

METHODS

We implemented a clinical pathway with a standardized approach with reduction in care variation and followed that by instituting performance improvement measures. The difference in outcome measurements as reported by TQIP for the year prior to implementation and the year following creation of the fragility fracture program was evaluated.

RESULTS

Benchmarking data demonstrated improved outcomes for patients with fragility fractures. Length of stay was significantly below national average, mortality remained below national average, and complication rates for UTIs and pressure ulcers were both reduced from 2014 to 2015 and below the national average.

CONCLUSION

The clinical pathway we adopted for the care of patients with fragility fractures has resulted in reduced lengths of stay, below average mortality, and improved discharge disposition.

Isolated cardiac troponin rise does not modify the prognosis in elderly patients with hip fracture

Perioperative myocardial infarction remains a life-threatening complication in noncardiac surgery and even an isolated troponin rise (ITR) is associated with significant mortality. Our aim was to assess the prognostic value of ITR in elderly patients with hip fracture.In this cohort study, all patients admitted between 2009 and 2013 in our dedicated geriatric postoperative unit after hip fracture surgery with a cardiac troponin I determination were included and divided into Control, ITR, and acute coronary syndrome (ACS) groups. The primary end point was a composite criteria defined as 6-month mortality and/or re-hospitalization. Secondary end points included 30-day mortality, 6-month mortality, and 6-month functional outcome.Three hundred twelve patients were (age 85 ± 7 years) divided into Control (n = 217), ITR (n = 50), and ACS (n = 45) groups. There was no significant difference for any postoperative complications between ITR and Control groups. In contrast, atrial fibrillation, acute heart failure, hemorrhage, and ICU admission were significantly more frequent in the ACS group. Compared to the Control group, 6-month mortality and/or rehospitalization was not significantly modified in the ITR group (26% vs. 28%, P = 0.84, 95% confidence interval [CI] of the difference -13%-14%), whereas it was increased in the ACS group (44% vs. 28%, P = 0.02, 95% CI of the difference 2%-32%). ITR was not associated with a higher risk of new institutionalization or impaired walking ability at 6 months, in contrast to ACS group.In elderly patients with hip fracture, ITR was not associated with a significant increase in death and/or rehospitalization within 6 months.

ORIF or Arthroplasty for Displaced Femoral Neck Fractures in Patients Younger Than 65 Years Old: An Economic Decision Analysis

BACKGROUND

The decision between open reduction and internal fixation (ORIF) and arthroplasty for a displaced femoral neck fracture in a patient ≤65 years old can be challenging. Both options have potential drawbacks; if a fracture treated with ORIF fails to heal it may require a revision operation, whereas a relatively young patient who undergoes arthroplasty may need revision within his/her lifetime. The purpose of this study was to employ decision analysis modeling techniques to generate evidence-based treatment recommendations in this clinical scenario.

METHODS

A Markov decision analytic model was created to simulate outcomes after ORIF, total hip arthroplasty (THA), or hemiarthroplasty in patients who had sustained a displaced femoral neck fracture between the ages of 40 and 65 years. The variables in the model were populated with values from studies with high-level evidence and from national registry data reported in the literature. The model was used to estimate the threshold age above which THA would be the superior strategy. Results were tested using sensitivity analysis and probabilistic statistical analysis.

RESULTS

THA was found to be a cost-effective option for a displaced femoral neck fracture in an otherwise healthy patient who is >54 years old, a patient with mild comorbidity who is >47 years old, and a patient with multiple comorbidities who is >44 years old. The average clinical outcomes of THA and ORIF were similar for patients 40 to 65 years old, although ORIF had a wider variability in outcomes based on the success or failure of the initial fixation. For all ages and cases, hemiarthroplasty was associated with worse outcomes and higher costs.

CONCLUSIONS

Compared with ORIF, primary THA can be a cost-effective treatment for displaced femoral neck fractures in patients 45 to 65 years of age, with the age cutoff favoring THA decreasing as the medical comorbidity and risk of ORIF fixation failure increase. Hemiarthroplasty has worse outcomes at higher costs and is not recommended in this age group.

Does cognitive/physical screening in an outpatient setting predict institutionalization after hip fracture?

Background

Institutionalization after hip fracture is a socio-economical burden. We examined the predictive value of Instrumental Activities of Daily Living (IADL) and Mini Mental State Examination (MMSE) for institutionalization after hip fracture to identify patients at risk for institutionalization.

Methods

Fragility hip fracture patients ≥65 years of age (n = 584) were comprehensively examined at a geriatric outpatient clinic 4 to 6 months after surgery and followed 1 year postoperatively. A telephone interview with a structured inquiry was performed at 1, 4, and 12 months after hip fracture.

Results

Age-adjusted univariate logistic regression analysis revealed that IADL and MMSE scores measured at the outpatient clinic were significantly associated with living arrangements 1 year after hip fracture. Multivariate logistic regression analysis established that institutionalization 1 year after hip fracture was significantly predicted by institutionalization at 4 months (odds ratio [OR] 16.26, 95 % confidence interval [CI] 7.37–35.86), IADL <5 (OR 12.96, 95 % CI 1.62–103.9), and MMSE <20 (OR 4.19, 95 % CI 1.82–9.66). A cut-off value of 5 was established for IADL with 100 % (95 % CI 96 %–100 %) sensitivity and 38 % (95 % CI 33 %–43 %) specificity and for MMSE, a cut-off value of 20 had 83 % (95 % CI 74 %–91 %) sensitivity and 65 % (95 % CI 60 %–70 %) specificity for institutionalization. During the time period from 4 to 12 months, 66 (11 %) patients changed living arrangements, and 36 (55 %) of these patients required more supportive accommodations.

Conclusion

IADL and MMSE scores obtained 4 to 6 months after hospital discharge may be applicable for predicting institutionalization among fragility hip fracture patients ≥65 years of age at 1 year after hip fracture. An IADL score of ≥5 predicted the ability to remain in the community. Changes in living arrangements also often occur after 4 months.

[Femoral fractures in elderly Brazilians: a spatial and temporal analysis from 2008 to 2012]

Fractures in the elderly (≥ 60 years) have a major public health impact and take a heavy social and economic toll. This article aimed to describe spatial and time trends in femoral fractures among elderly men and women in all regions of Brazil. Bayesian descriptive analyses of spatial and time series were performed on data obtained from the Hospital Information System of the Brazilian Unified National Health System, using Poisson regression for femoral fractures in individuals 60 years of age or older from 2008 to 2012. There were more than 181,000 femoral fractures during this period, predominantly in women, without important spatial correlations or temporal differences. Despite the lack of temporal and spatial correlations, the number of femoral fractures in elderly Brazilians was high, with heavy financial and social costs. Public health policies are urgently needed to control predisposing factors for femoral fractures in elderly Brazilians.

A Guide to Improving the Care of Patients with Fragility Fractures, Edition 2

Over the past 4 decades, much has been learned about the pathophysiology and treatment of osteoporosis, the prevention of fragility fractures, and the perioperative management of patients who have these debilitating injuries. However, the volume of published literature on this topic is staggering and far too voluminous for any clinician to review and synthesize by him or herself. This manuscript thoroughly summarizes the latest research on fragility fractures and provides the reader with valuable strategies to optimize the prevention and management of these devastating injuries. The information contained in this article will prove invaluable to any health care provider or health system administrator who is involved in the prevention and management of fragility hip fractures. As providers begin to gain a better understanding of the principles espoused in this article, it is our hope that they will be able to use this information to optimize the care they provide for elderly patients who are at risk of or who have osteoporotic fractures.

Mortality after distal radius fracture in men and women aged 50 years and older in southern Norway

Increased mortality rates in patients sustaining hip and vertebral fractures are well documented; however in distal radius fracture patients the results are conflicting. The aim of this study was to examine short- and long-term mortality in distal radius fracture patient in comparison with the background population. Patients aged ≥50 years with distal radius fracture living in Southern Norway who suffered a fracture in the two year period 2004 and 2005 were included in the study. The mortality risk of the standard Norwegian population was used to calculate the standardized mortality ratio (SMR). The number of distal radius fractures was 883 (166 men and 717 women). Mean age was 69 years (men 65 years and women 70 years). After one year the overall mortality rate was 3.4% (men 5.4% and women 2.9%) and after five years 4.6% (men 4.0% and women 4.8%). The SMR for men and women compared to the Norwegian population for the first year was 1.6 (95% confidence interval (CI): 0.6, 2.7) and 0.9 (95% CI: 0.4, 1.2), respectively, and after five years 1.7 (95% CI: 0.3, 3.0) and 2.0 (95% CI: 1.2, 2.7). Stratified on age groups (50–70 and >70 years) an increased SMR was only seen in female patients aged >70 years five years after the fracture (SMR: 1.9, 95% CI: 1.1, 2.6). In conclusion, increased SMR was found in female patients aged >70 years five years after the distal radius fracture, but not in men or in women younger than 70 years.

Osteoporosis and fractures in HIV/hepatitis C virus coinfection: a systematic review and meta-analysis

OBJECTIVE

There is growing evidence that fracture risk is increased in individuals with HIV and/or hepatitis C virus (HCV) infection. We systematically reviewed the literature to determine whether prevalence of osteoporosis and incidence of fracture is increased in HIV/HCV-coinfected individuals.

DESIGN

A systematic review and meta-analysis.

METHODS

A search was performed of Medline, Scopus and the Cochrane Library databases, as well as of abstracts from annual retroviral, liver and bone meetings (up to 2013) for studies with bone mineral density (BMD) or bone fracture data for HIV/ HCV-coinfected individuals. Osteoporosis odds ratios (ORs) and fracture incidence rate ratios (IRRs) were estimated from studies with data on HIV-monoinfected or HIV/HCV uninfected comparison groups.

RESULTS

Of 15 included studies, nine reported BMD data and six reported fracture data. For HIV/HCV-coinfected, the estimated osteoporosis prevalence was 22% [95% confidence interval (95% CI) 12–31] and the crude OR for osteoporosis compared with HIV-monoinfected was 1.63 (95% CI 1.27-2.11). The pooled IRR of overall fracture risk for HIV/HCV-coinfected individuals was 1.77 (95% CI 1.44-2.18) compared with HIV-monoinfected and 2.95 (95% CI 2.17-4.01) compared with uninfected individuals. In addition to HIV/HCV-coinfection, older age, lower BMI, smoking, alcohol and substance use were significant predictors of osteoporosis and fractures across studies.

CONCLUSION

HIV/HCV coinfection is associated with a greater risk of osteoporosis and fracture than HIV monoinfection; fracture risk is even greater than uninfected controls. These data suggest that HIV/HCV-coinfected individuals should be targeted for fracture prevention through risk factor modification at all ages and DXA screening at age 50.

Fatal injury caused by low-energy trauma - a 10-year rural cohort

Background

Death after injury with low energy has gained increasing focus lately, and seems to constitute a significant amount of trauma-related death. The aim of this study was to describe the epidemiology of deaths from low-energy trauma in a rural Norwegian cohort.

Methods

All deaths from external causes in Finnmark County, Norway, from 1995 to 2004 were identified retrospectively through the Norwegian Cause of Death Registry. Deaths caused by hanging, drowning, suffocation, poisoning, and electrocution were excluded. Trauma was categorised as high energy or low energy based on mechanism of injury. All low-energy trauma deaths were then reviewed.

Results

There were 262 cases of trauma death during the period. Low-energy trauma counted for 43% of the trauma deaths, with an annual crude death rate of 13 per 100,000 inhabitants. Low falls accounted for 99% of the injuries. Fractures were sustained in 89% of cases and head injuries in 11%. Ninety per cent of patients had pre-existing medical conditions, and the median age was 82 years. Death was caused by a medical condition in 85% of cases. Fifty-two per cent of the patients died after discharge from the hospital.

Conclusion

In this cohort, low-energy trauma was a significant contributor to trauma related death, especially among elderly and patients with pre-existing medical conditions.

Mortality following the first hip fracture in Norwegian women and men (1999-2008). A NOREPOS study

Hip fractures are associated with increased mortality and their incidence in Norway is one of the highest worldwide. The aim of this nationwide study was to examine short- and long-term mortality after hip fractures, burden of disease (attributable fraction and potential years of life lost), and time trends in mortality compared to the total Norwegian population. Information on incident hip fractures between 1999 and 2008 in all persons aged 50 years and older was collected from Norwegian hospitals. Death and emigration dates of the hip fracture patients were obtained through 31 December 2010. Standardized mortality ratios (SMRs) were calculated and Poisson regression analyses were used for the estimation of time trends in SMRs. Among the 81,867 patients with a first hip fracture, the 1-year excess mortality was 4.6-fold higher in men, and 2.8-fold higher in women compared to the general population. Although the highest excess mortality was observed during the first two weeks post fracture, the excess risk persisted for twelve years. Mortality rates post hip fracture were higher in men compared to women in all age groups studied. In both genders aged 50 years and older, approximately 5% of the total mortality in the population was related to hip fractures. The largest proportion of the potential life-years lost was in the relatively young-old, i.e. less than 80 years. In men, the 1-year absolute mortality rates post hip fracture declined significantly between 1999 and 2008, by contrast, the mortality in women increased significantly relatively to the population mortality.

Surgical procedures in femoral neck fractures in Finland: a nationwide study between 1998 and 2011

PURPOSE

For femoral neck fractures, recent scientific evidence supports cemented hemiarthroplasty (HA) over uncemented HA and suggests that total hip arthroplasty (THA) should be performed more frequently. We report the current surgical trends in treating femoral neck fractures in Finland.

METHODS

The study was conducted using the Finnish National Hospital Discharge Register and included all Finns at least 50 years of age who underwent surgery for femoral neck fractures from 1998 through 2011. Age- and sex-specific incidence rates and annual proportion of each treatment method were calculated.

RESULTS

During 1998-2011, a total of 49,514 operations for femoral neck fracture were performed in Finland. The proportion of uncemented HA increased from 8.1% in 2005 to 22.2% in 2011. During the same time, the proportion of cemented HA decreased from 63.9 to 52.5%, internal fixation decreased from 23.2 to 16.1% and THA increased from 4.9 to 9.2%.

CONCLUSIONS

Between 2005 and 2011, the proportion of uncemented HA for femoral neck fractures increased markedly in Finland, while cemented HA and internal fixation declined. During this time, the use of THA nearly doubled. The current evidence-based guidelines for treatment of femoral neck fractures were mainly followed, but the increase in uncemented HA procedures contradicts recent scientific evidence.

Orthopedic surgery and its complication in systemic lupus erythematosus

Systemic lupus erythematosus (SLE) is a multi-systemic immune-complex mediated autoimmune condition which chiefly affects women during their prime year. While the management of the condition falls into the specialty of internal medicine, patients with SLE often present with signs and symptoms pertaining to the territory of orthopedic surgery such as tendon rupture, carpal tunnel syndrome, osteonecrosis, osteoporotic fracture and infection including septic arthritis, osteomyelitis and spondylodiscitis. While these orthopedic-related conditions are often debilitating in patients with SLE which necessitate management by orthopedic specialists, a high index of suspicion is necessary in diagnosing these conditions early because lupus patients with potentially severe orthopedic conditions such as osteomyelitis frequently present with mild symptoms and subtle signs such as low grade fever, mild hip pain and back tenderness. Additionally, even if these orthopedic conditions can be recognized, complications as a result of surgical procedures are indeed not uncommon. SLE per se and its various associated pharmacological treatments may pose lupus patients to certain surgical risks if they are not properly attended to and managed prior to, during and after surgery. Concerted effort of management and effective communication among orthopedic specialists and rheumatologists play an integral part in enhancing favorable outcome and reduction in postoperative complications for patients with SLE through thorough pre-operative evaluation, careful peri-operative monitoring and treatment, as well as judicious postoperative care.

Outcome after osteosynthesis of hip fractures in nonagenarians

Background

Hip fractures in the elderly population are associated with high morbidity and mortality. However, there is still a lack of information on mortality and loss of independence in extremely elderly people with a hip fracture.

Objective

To study functional outcomes and mortality after osteosynthesis of hip fractures in very old patients in our clinic.

Patients and methods

Hospital charts of all patients over 90 years old who were operated for a hip fracture between January 2007 and December 2011 were reviewed. Outcome measures were mortality, preoperative and postoperative mobility, and loss of independence.

Results

A total of 149 patients were included; 132 (89%) women, median age 93.5±2.45 years. Thirty-six (24%) patients were classified as American Society of Anesthesiologists (ASA) grade 2, 104 (70%) as ASA grade 3, and nine (6%) as ASA grade 4. The Charlson comorbidity index (CCI) score was 2 or less in 115 (77%) patients and 34 (23%) patients scored 3 or more points. Short-term survival was 91% and 77% at 30 days and 3 months, respectively. Long-term survival was 64%, 42%, and 18% at 1, 3, and 5 years after surgery, respectively. Survival was significantly better in patients with lower ASA scores (P=0.005). No significant difference in survival was measured between patients according to CCI score (P=0.13). Fifty-one percent of patients had to be accommodated in an institution with more care following treatment, and 57% were less mobile after osteosynthesis of a hip fracture.

Conclusion

Our study shows that short-term mortality rates in very elderly patients with a hip fracture are high and there is no clear predictive value for mortality. ASA classification is the best predictive value for overall mortality. A large proportion of these patients lost their independence after osteosynthesis of a hip fracture.

Predictors of short- and long-term mortality in males and females with hip fracture - a prospective observational cohort study

BACKGROUND

Hip fracture is associated with increased mortality. Our aim was to study potential risk factors, including osteoporosis, associated with short- and long-term mortality in a prospectively recruited cohort of fragility hip fracture patients.

METHODOLOGY/PRINCIPAL FINDINGS

Fragility hip fracture patients aged >50 years admitted to a county hospital in Southern Norway in 2004 and 2005 were consecutively identified and invited for assessment. Patients with high energy or pathological fractures, patients with confusion, serious infections or who were non-residents in the catchment area were excluded. As part of a clinical routine, data were collected using questionnaires. Standardized bone density measurements of lumbar spine and hip were performed. Potential predictors of hip fracture mortality were tested using univariate and multivariate logistic regression analysis. A total of 432 hip fracture patients (129 males and 303 females) were prospectively identified. Among them 296 (85 males and 211 females) patients [mean age 80.7 (SD 9.1)] were assessed at the Osteoporosis center. Variables independently associated with short-term mortality (after 1 year) were in females older age [Odds Ratio (OR) 6.95] and in males older age (OR 5.74) and pulmonary disease (OR 3.20), whereas no associations were observed with mortality for 3 months after the fragility hip fracture. Variables independently associated with 5 years mortality in males was osteoporosis (OR 3.91) and older age (OR 6.95), and in females was dementia (OR 4.16) and older age (OR 2.80).

CONCLUSION

Apart from known predictors as age and comorbidity osteoporosis in our study was identified as a potential independent predictor of long-term hip fracture mortality in males. This is of particular importance as treatment with bisphosphonates after hip fracture has been shown to reduce hip fracture mortality and may be a clinical target to reduce the burden of the disease. Further studies however are needed to confirm the validity of this finding.
