Objective: Postoperative pneumonia is among the most common complications in elderly patients after hip fracture surgery. We implemented a proactive postoperative pneumonia prevention protocol and analyzed the incidence of postoperative pneumonia in elderly patients (≥70 years of age) receiving this protocol after hip fracture surgery versus those receiving usual care before the protocol's implementation at our institution.Materials and Methods: From November 2018 to October 2019, the proactive postoperative pneumonia prevention protocol was implemented. The treatment included intensified physical therapy, postoperative pulmonary exercises and oral care, in addition to the usual surgical treatment for elderly patients with hip fracture. The intervention cohort data were compared with a historical control cohort treated from July 2017 to June 2018. The primary outcome of this study was the incidence of postoperative pneumonia in both groups, diagnosed according to the presence of two of three of the following: elevated infection parameters, radiologic examination confirmation of pneumonia of the chest or clinical suspicion.Results: A total of 494 patients (n= 249 in the historical control cohort and n=245 in the intervention cohort) were included. A total of 69 patients developed postoperative pneumonia. The incidence of postoperative pneumonia was significantly lower (6.7 percentage points) in the group receiving the proactive postoperative pneumonia prevention protocol (17.3% in the historical control cohort vs 10.6% in the intervention cohort; p=0.033).Discussion and Conclusion: A proactive postoperative pneumonia prevention protocol showed promise in decreasing the occurrence of postoperative pneumonia after hip fracture surgery in elderly patients.

Introduction: Identification of high-risk hip fracture patients in an early stage is vital for guiding surgical management and shared decision making. To objective of this study was to perform an external international validation study of the U-HIP prediction model for in-hospital mortality in geriatric patients with a hip fracture undergoing surgery.Materials and Methods: In this retrospective cohort study, data were used from The American College of Surgeons National Surgical Quality Improvement Program. Patients aged 70 years or above undergoing hip fracture surgery were included. The discrimination (c-statistic) and calibration of the model were investigated.Results: A total of 25,502 patients were included, of whom 618 (2.4%) died. The mean predicted probability of in-hospital mortality was 3.9% (range 0%-55%). The c-statistic of the model was 0.74 (95% CI 0.72-0.76), which was comparable to the c-statistic of 0.78 (95% CI 0.71-0.85) that was found in the development cohort. The calibration plot indicated that the model was slightly overfitted, with a calibration-in-the-large of 0.015 and a calibration slope of 0.780. Within the subgroup of patients aged between 70 and 85, however, the c-statistic was 0.78 (95% CI 0.75-0.81), with good calibration (calibration slope 0.934).Discussion and Conclusion: The U-HIP model for in-hospital mortality in geriatric hip fractures was externally validated in a large international cohort, and showed a good discrimination and fair calibration. This model is freely available online and can be used to predict the risk of mortality, identify high-risk patients and aid clinical decision making. [ABSTRACT FROM AUTHOR]

Objective: To compare the Charlson Comorbidity Index (CCI) and American Society of Anesthesiologists (ASA) Physical Status Classification used in two prediction models for 30-day mortality after hip fracture surgery.Study Design and Setting: Data from 3651 patients (mean age: 83 years) from a Norwegian University Hospital were retrospectively obtained and randomly divided into two cohorts: a model cohort (n = 1825) to develop two prediction models with CCI and ASA as the main predictors, and a validation cohort (n = 1826) to assess the predictive ability of both models. A receiver operating characteristic (ROC) curve determined the best model to predict mortality.Results: Area under the ROC curve at 30 days was 0.726 (p = 0.988) for both the CCI- and ASA-model. The chosen cut-off-points on the ROC curve for CCI- and ASA-model corresponded to similar model sensitivities of 0.657 and specificities of 0.680 and 0.679, respectively. Hence, each model predicts correctly 66% (n = 96) of the mortalities and 68% (n = 1132 and n = 1131) of the survivals. 23% (n = 33) of the mortalities were predicted by neither model.Conclusion: The CCI- and ASA-model had equal predictive ability of 30-day mortality after hip fracture. Considering the effort involved in calculating Charlson Comorbidity Index score, the ASA score may be the preferred tool to predict the 30-day mortality after hip fracture. [ABSTRACT FROM AUTHOR]

Tranexamic acid (TXA) is a cheap and powerful drug that has several uses in surgery and is well established in elective orthopaedic surgery. At present, limited small studies have looked into its role in the acute hip fracture. Transfusion in the geriatric population presents risks and increased costs to healthcare systems around the world. Our retrospective study looks at the role of TXA administration at induction for both intracapsular fracture requiring hemiarthroplasty and our preferred method of fixation of extracapsular fracture by intramedullary nail (IM nail). We show a statistically significant reduction in the number of patients requiring transfusion as well as mean haemoglobin (Hb) drop in those undergoing hemiarthroplasty. This was not replicated in those undergoing IM nail fixation. Both groups showed no increase in 1-year mortality or thromboembolic events following TXA administration. These results support the use of TXA for hemiarthroplasty for intracapsular hip fractures over the age of 60.Objectives: The aim of this pre and post interventional study looks at the effects of intravenous administration of tranexamic acid on induction for elderly patients undergoing hemiarthroplasty or intramedullary nail fixation for hip fractures.Design: Pre and post interventional, randomised observational study SETTING: Large hip fracture unit, Level 2 Trauma Centre, single centre PATIENTS: Two arms of the study looking at those aged above the age of 60 undergoing hemiarthroplasty and intramedullary nail fixation without and with tranexamic acid on induction.Results: 12.1% of hemiarthroplasties required post-operative transfusion without tranexamic acid compared to 2.6% of those with tranexamic acid (n=15 vs n=3 respectively, p=0.006). Equally, the mean Hb drop in g/L is reduced in those with tranexamic acid compared to those without (mean Hb = 14.6 vs 17.7 respectively, p=0.034). This was not replicated in the IM nail group between those without and those with tranexamic acid (n=31 vs n=20 respectively, p= 0.16). The mean Hb drop in g/L was not statistically significant in the tranexamic acid arm compared to without (mean Hb = 19.2 vs mean Hb = 21.9, p=0.11). Gross reporting of thromboembolic events did not demonstrate an increase in the number of those with DVT, PE, MI or stroke. 1-year mortality was not statistically significant in either hemiarthroplasty or IM nail fixation following tranexamic acid administration.Conclusions: Tranexamic acid both statistically significantly reduces the number of patients requiring transfusion post hemiarthroplasty and also the value of mean Hb drop without appearing to increase in thromboembolic events or 1 year mortality rates. This does not appear to be emulated in the IM nail fixation although both thrombotic events and 1-year mortality rates are also not affected by administration of TXA. We propose that TXA has a role in hemiarthroplasty surgery in reducing post-operative transfusions.Level Of Evidence: Level 3 - retrospective cohort study. [ABSTRACT FROM AUTHOR]

Background: Hip fractures are a large burden on the health care systems of developed nations. Patients usually have multiple co-morbidities and the pre-injury use of anticoagulants and anti-platelet medication is common.Materials and Methods: This study used a single hospital hip fracture database to facilitate a retrospective analysis of the impact of anti-coagulation and anti-platelet therapy on mortality and complications after surgical management of hip fractures. There were 92 patients on warfarin, 69 on DOAC, 260 antiplatelet patients and 617 control patients.Results: Mortality rates at 30 days were 4.8% for the control group, 12.6% for the antiplatelet group, warfarin 7.0%, 9.5% for Direct Oral Anticoagulant (DOAC) group, p = 0.004. Mortality rates at 1 year were 22.4% for the control group, 32.3% for the antiplatelet group, 29.3% for the warfarin group and 29.0% for DOAC group (p=0.007). Amongst complications, significant differences were found in transfusion (DOAC) and wound ooze (warfarin) rates, but the study did not detect significant clinical consequences arising from these differences. A matched analysis for age, sex, and ASA was undertaken to look in more detail at mortality data. Some mortality differences remained between groups with anti-platelet medication associated with increased mortality, but the differences no longer appeared to be significant. Our data suggests that this is a non-causal association, which could be incorporated into predictive mortality risk scores such as the Nottingham hip fracture score.Conclusion: We believe that pre-injury antiplatelet therapy is a strong indicator for high risk patients with higher expected mortality after hip fracture surgery. We saw no evidence to support delayed surgery in patients taking DOACs. [ABSTRACT FROM AUTHOR]

Introduction: Early mortality following hip fracture surgery remains a significant issue with a much studied, multifactorial aetiology. This study designed to test the variables affecting 30 day mortality in a socially deprived cohort against national models, and secondarily aimed to uncover and quantify new risk factors.Methods: This was a single centre retrospective study based on National Hip Fracture Database (NHFD) data for 3176 hip fracture patients from 1st May 2008 to December 31st 2017. Data was condensed into a single anonymised workbook and logistic regression used to analyse associations with 30 day mortality. Firstly, the 6 casemix variables used by the NHFD were modelled. Secondarily, a new optimised model based on our data was created.Results: Gross mortality was 11.1% since May 2008 (344/3074). There were 1978 patients in our cohort with sufficient data to run the NHFD casemix model. Overall, this proved fair with a similar area under ROC curve to nationally (0.75 vs. 0.76), although the Odds Ratios (OR) of individual variables differed. The optimised casemix model suggested two powerful prognostic indicators for 30 day mortality, namely delay to theatre for clinical reasons (OR =3.98, p-value=0.02) and whether the patient was mobilised day one post op (OR=0.21, p-value=0.00). Delay to theatre for non clinical reasons conveyed only a marginal and statistically insignificant increase in risk (OR=1.15, p-value=0.77).Conclusion: This study has confirmed the NHFD casemix adjusted model is a fair barometer for units treating a socially deprived cohort. It also has shown a clear differentiation between risk conveyed by delay to theatre for clinical reasons and suggests delay for non-clinical reasons, although clearly not desired, may not have a significant effect on death rate. Finally, it both amplifies and prompts further investigation into the potential benefit of early mobilisation. [ABSTRACT FROM AUTHOR]

Objective: To estimate the potential influence of pre-operative patient condition on the benefit of earlier hip fracture surgery for elderly patients.Background: Many studies emphasize the benefit of earlier hip fracture surgery for patient survival. However less is known regarding how this relationship is influenced by clinical factors which could serve as potential contra-indicators for earlier surgery. Rushed surgery of patients with contra-indications may even compromise their survival.Methods: A retrospective study of patients aged 65 and above with an isolated hip fracture following trauma, based on data from 19 hospitals of the national trauma registry available for the years 2015-2016. Registry data was crossed with data on co-morbidities and medication intake from the biggest health insurance agency in the country, serving more than 50% of the country's population. Mediation analysis was performed on a wide list of co-morbidities, medications and clinical test results in order to establish the mediation of their relationship with inhospital mortality by earlier hip fracture surgery. Factors found significant in the mediation analysis were utilized to adjust a logistic regression for predicting inhospital mortality by function of waiting time to surgery and patient's sex and age.Results: Anti-coagulant and anti-platelet intake; test results pointing to decreased kidney function and being diagnosed with diabetes or Ischemic Heart Disease were found to be significantly mediated in their influence on inhospital mortality by hip fracture surgery. Despite anti-platelet intake and kidney function having a significant impact on mortality in the multi-variate analysis, the positive effect of earlier hip surgery on survival remained unchanged after adjustment.Conclusions: Earlier hip fracture surgery was found to be beneficial for elderly patients even when their co-morbidities and medication intake are taken into account.

Background: As the aging population progresses, the number of elderly hip fracture patients is increasing. Elderly patients with hip fractures have a high risk of perioperative complications. One of the major complications after surgery is surgical site infection (SSI), which requires additional surgical interventions and is associated with increased mortality. Previous literature has shown that the risk of SSI is higher during the summer season in orthopedic surgery. However, little is known about the seasonal differences in the risk of SSI after hip fracture surgery. In this study, we aimed to identify the association between seasonality and SSI.Methods: We enrolled a total of 330,803 patients undergoing hip fracture surgery (65 years or older) using the Japanese Diagnosis Procedure Combination database. The study period was from April 1, 2011, to March 31, 2016. The data were analyzed to determine the association between seasonality and the incidence of SSI, debridement procedure. The primary outcome was the incidence of SSI and debridement. Other risk factors of SSI and debridement were investigated including seasons and confounders such as sex, age, BMI, smoking status, anticoagulant intake, comorbidities, surgical procedure based on medical diagnosis, waiting times for the surgery, and hospital surgical volume based on the previous literature, the risk of SSI and debridement.Results: Hip fracture surgeries performed in summer showed the highest risk for SSI and debridement. The risk for SSI was significantly associated with spring, and summer compared to winter (odds ratio [OR], 1.18; p, 0.016; OR, 1.19; p, 0.012, respectively). The incidence of debridement procedures after the initial surgery was also associated with spring, summer, and fall: the risk was the highest in summer (OR, 1.34; p, <0.001). Obesity, smoking history, number of comorbidities, anticoagulant intake before surgery, longer waiting time for surgery, and small hospital surgical volume were significantly associated with the risk of SSI.Conclusions: We found a significant association between SSI after surgery for hip fractures and seasonality. Surgeries performed in summer had the highest risk for SSI and subsequent debridement procedures. [ABSTRACT FROM AUTHOR]

Background: In 2040 the estimated number of people with a hip fracture in the Netherlands will be about 24,000. The medical care for this group of patients is complicated and challenging. Multidisciplinary approaches aim to improve clinical outcome. Quality indicators that gain insight in the treatment and outcome of hip fracture patients may help to optimize and monitor the standard of medical care. The Dutch Hip Fracture Audit (DHFA) is a new multidisciplinary quality indicator that is implemented in the Dutch hospitals in 2017.Aim: The aim of this study was to determine the effect of the implementation of the DHFA on 30-day mortality, length of hospital stay and time until surgery in elderly with a hip fracture in the Netherlands.Methods: A multicenter retrospective comparative cohort study was conducted and data were extracted from the Dutch Nationwide Trauma Registration (LTR). Included were patients aged 60 years and older with a hip fracture (femoral neck and trochanteric) and admitted in one of the ten participating hospitals registered in 2015 and 2017. Data from 2015, before implementation of DHFA, were compared with data from 2017, when the DHFA was implemented. The primary outcome was 30-day mortality; secondary outcomes were length of hospital stay and time until surgery. Multivariable regression models were used to compare outcomes between groups.Results: 3808 patients were included, 1839 in the 2015 cohort and 1969 in the 2017 cohort. 29% was male; mean age 82 years. The multilevel analysis showed a positive non-significant difference between groups on the primary outcome30-day mortality (OR adjusted 1.23, 95%CI 0.93 - 1.63). The secondary outcomes length of hospital stay (adjusted effect estimates -0.002, 95%CI -0.03 - 0.03) and time until surgery (adjusted effect estimates 0.292, 95%CI -2.68 - 3.26) showed no differences between groups.Conclusions: Implementation of the DHFA quality indicator does have a positive non-significant trend on 30-day mortality, but showed no impact on length of hospital stay and time until surgery. More research on relevant quality indicators seems therefore mandatory. [ABSTRACT FROM AUTHOR]

Background: Hip fracture causes disability and excess mortality in the aging population. Acute kidney injury (AKI), is known to diminish survival of critically ill and trauma patients. AKI is also a common perioperative complication among surgical patients. We examined the effect of AKI on the survival of hip fracture patients in a Finnish hip fracture population and the risk factors for AKI in a prospective study.Methods: The study cohort constituted of 486 consecutive low-energy trauma hip fracture patients referred to Satakunta Central Hospital (Pori, Finland) and Turku University Hospital (Turku, Finland). The patients underwent standard diagnostics and treatment in the emergency department (ER) and were operated according to the local treatment protocol. Serum creatinine (sCr) was analyzed daily pre- and post-operatively during the hospital stay. Patients were divided into groups; AKI and non-AKI based on Kidney Disease: Improving Global Outcomes (KDIGO) criteria.Results: The incidence of AKI in the study cohort was 8.4% (40/475). Eleven patients were excluded due to missing sCr data. The baseline characteristics of AKI and non-AKI groups differed significantly concerning baseline sCr but were otherwise similar. At 90-day follow-up, the overall mortality was 14.4%. Patients with AKI had a significantly higher mortality (35.0%) than those with no AKI (12.7%) (p < 0.001). Dementia, preoperative sCr and any stage of AKI were independent predictors for mortality. Dementia and preoperative sCr were independently associated with post-operative AKI.Conclusion: In this study AKI was a significant factor associated with a 3 -fold mortality during the first three months after surgery for low-energy trauma hip fracture.

Introduction: Although early surgery for elderly patients with hip fracture is recommended in existing clinical guidelines, the results of previous studies are inconsistent. The aim of this study was to compare postoperative outcomes of early and delayed surgery for elderly patients with hip fracture.Materials and Methods: In this retrospective study using a national inpatient database in Japan, patients aged 65 years or older who underwent surgery for hip fracture between July 2010 and March 2014 were included. Early surgery was defined as surgery on the day or the next day of admission. Assessed outcomes included death within 30 days and hospital-acquired pneumonia.Results: In this cohort, 47,073 (22.5%) patients underwent surgery for hip fractures within two days of admission (early surgery group) and 161,805 (77.5%) underwent surgery for hip fractures thereafter (delayed surgery group). Early surgery was significantly associated with lower odds for hospital-acquired pneumonia (odds ratio, 0.42; 95% confidence interval, 0.25-0.69) and pressure ulcers (odds ratio, 0.56, 95%CI: 0.33-0.96, p = 0.035), but was not associated with 30-day mortality (odds ratio, 0.96; 95% confidence interval, 0.49-1.86) or pulmonary embolism (odds ratio, 1.62, 95%CI: 0.58-4.52, p = 0.357).Conclusions: These results support current guidelines, which recommend early surgery for elderly hip fractures patients.

Aim: We aim to assess post-operative CRP serum values in a cohort of patients who underwent surgical treatment for neck of femur fracture (NOF#), and whether CRP is a valid tool for the assessment of these patients post-operatively.Study Design and Methods: Retrospective analysis was carried out on all NOF#'s admitted for surgical fixation between August 2015 and July 2016 in a district general hospital. Primary analysis included serum CRP levels until day 7 post-operatively, with secondary analysis of any documented evidence of post-operative complications (medical and surgical) within 30 days post-operatively.Results: A total of 365 patients were surgically treated for NOF#'s over the study period. CRP serum levels peaked over the first two days post-operatively to median (IQ range) of 226 mg/L (158-299 mg/L), decreasing to 67 mg/L (45.5-104 mg/L) by day 7 post-operatively. 116 patients had documented post-operative complications within 30 daysof operation. CRP levels in patients with and without complications showed no statistical significance in day-1, day-2 and day-3 post-operatively. However, a significant difference was demonstrated on day-4 (p = 0.017), day-5 (p = 0.003), day-6 (p = 0.02) and day-7 (p = 0.031).Conclusions: During the first three days of the postoperative period we cannot recommend routine CRP serum blood test monitoring in NOF# patients, as it is not diagnostic in the acute inflammatory phase for medical or surgical complications.

Background: The Russel-Taylor type 2B fractures compromised the trochanteric region and medial buttress of proximal femur. This fracture pattern limits the choice of implants and raises the risk of adverse outcomes. We aimed to (i) determine the outcome of Russel-Taylor type 2B fractures treated using reverse less invasive stabilization system plates (LISS-DF) and to (ii) learn what factors affected outcomes after osteosynthesis with reverse LISS plates.Design: A retrospective study SETTING: The study was conducted at a Level III trauma center in Taiwan.Methods: Twenty-five consecutive patients presenting with a Russel-Taylor type 2B fracture were enrolled. All cases were treated with reverse LISS plates. A Modified Radiographic Union Scale for Femur (RUSF), Radiographic parameters, functional scores, and complications were assessed.Results: Union occurred in 21 cases at an average of 18.8 weeks. The average immediate postoperative neck-shaft angle was 130° (range: 122-135°) compared with 139° (range: 135-141°, p=0.05) on the contralateral side. Two cases had complications of proximal screws cutting out and two cases had broken implants. Finally, all 4 cases required repeated surgeries (16%). Malunion occurred in 4 patients and early mechanical failure (proximal screws cut out) occurred in 2. There was a significant difference in the purchase index of the proximal screws between cases with redisplacement and those without (26.4mm and 98.6mm, p=0.01).Conclusions: The use of reverse LISS plate appeared to be an alternative procedure for the specific pattern in the present study. We recommend using this reverse locking plate to treat unstable proximal femoral fractures with meticulous techniques of placing plates. Adequate purchase of the proximal locking screws might decrease the risks of complications. [ABSTRACT FROM AUTHOR]

In patients undergoing hip hemiarthroplasty (HHA) secondary to proximal femur fracture, acute periprosthetic joint infection (PJI) is one of the most important complications. We have detected an increased risk of PJI in chronic institutionalized patients (CIPs), and a higher number of early postoperative infections are caused by Gram-negative bacteria (GNB), not covered by the current prophylaxis (cefazolin in noninstitutionalized patients (NIPs) and cotrimoxazole in CIPs). We sought to compare infection characteristics between NIPs and CIPs, analyzing predisposing factors, causative pathogens, and antibiotic prophylaxis-related microbiological characteristics. We performed a retrospective review of our prospective institutional database to identify all patients consecutively admitted for HHA to treat proximal femur fracture at our centre between 2011 and 2013. PJI was diagnosed in 21 of 381 (5.51%) patients, with 10 of 105 (9.52%) in the CIP group and 11 of 276 (3.99%) in the NIP group, and statistical significance was achieved. GNB accounted for PJI in 14 (66.67%) patients. We detected a single case of methicillin-resistant Staphylococcus aureus (MRSA) infection in the NIP group. We confirm a higher risk of acute PJI among institutionalized patients, commonly caused by Gram-negative microorganisms, which are not covered by the current prophylaxis. New prophylactic strategies should be investigated in order to reduce this problem. [ABSTRACT FROM AUTHOR]

Pre-operative digital templating allows the surgeon to foresee any anatomical anomalies which may lead to intra-operative problems, and anticipate appropriate instruments and implants required during surgery. Although its role is well-established in successful elective total hip arthroplasty, little work has been done on its use in hip hemiarthroplasty in neck of femur fractures. We describe our initial experience of digital templating in 40 consecutive patients who have undergone cemented hip hemiarthroplasty, assessing templating accuracy between templated implant sizes to actual implant sizes. 81% of implanted heads were templated to within two head sizes, and 89% of implanted stems were templated to within two sizes. Although there was a moderately strong correlation of 0.52 between templated and actual head sizes, this correlation was not demonstrated in femoral stem sizes. Mean leg length discrepancy was -2.5mm (S.D. 8.5), and the mean difference in femoral offset between the operated and non-operated hip was -1mm (S.D. 4.4). Digital templating is a useful adjunct to the surgeon in pre-operative planning of hip hemiarthroplasty in the restoration of leg length and femoral offset. However, its accuracy is inferior to that of elective total hip arthroplasty. [ABSTRACT FROM AUTHOR]

Introduction: Intracapsular hip fractures (ICHF) are a common cause of morbidity and mortality and pose a great economic burden on the health care systems. Appropriate surgical treatment requires balancing optimal outcomes with the cost of treatment to the health care system. While in elderly patients with displaced ICHF arthroplasty became the standard of care, the internal fixation method for conserving the femoral head in younger patients or in nondisplaced ICHF is still in debate. We compared a dynamic locking plate with the standard cancellous cannulated screws (CCS) for treatment of nondisplaced ICHF.Methods: All patients treated with internal fixation for nondisplaced ICHF between July 2009 and December 2012 at our level one trauma center were included in this study. Patients treated with Targon FN (Aesculap) implants and CCS (Synthes) were compared. Charts were reviewed for demographics, intraoperative data and peri/post operative complications retrospectively. Radiographical analysis, pain (VAS), quality of life (SF12) and function (MHHS) data were prospectively gathered.Results: One hundred and fifteen non-displaced ICHFs were treated with internal fixation, 81 with CCS and 34 with Targon FN implant; the mean follow-up was 19 and 28 months, respectively. Group fracture characteristics (Garden/Powel classification), and demographics, excluding age, were not significantly different. Post-operative revision rates of the Targon FN and CCS groups, perioperative complications were not statistically different (p>0.05). Quality of life (SF-12), function (Modified Harris Hip Score) and Visual Analogue Scale (VAS) pain scores were not statistical different.Conclusions: Complication rates and clinical outcomes for the treatment of nondisplaced ICHF with Targon FN and SCC showed no significant differences. Based on this evidence in consideration of the substantial cost differential between the Targon FN and SCC we suggest SCC for treatment of nondisplaced ICHF.Level Of Evidence: III.

Reverse oblique intertrochanteric fractures have unique mechanical characteristics and are often treated with intramedullary implants. We compared the outcomes of the reconstruction trochanteric antegrade nail (TAN) with the proximal femoral nail antirotation (PFNA). Between July 2008 and February 2014, we reviewed all patients with reverse oblique intertrochanteric fractures treated at our hospital. Patients with pathological fractures and those who were treated with other than TAN and PFNA nailing systems were excluded. Preoperative assessment included the Abbreviated mental test score (AMT), the ASA grade, pre-injury mobility and place of residence. Postoperative outcome measures included the type of implant used, time to fracture union, failures of fixation and revision surgeries. Fifty-eight patients were included and divided into two groups based on the treatment: 22 patients treated with TAN and 36 patients treated with PFNA systems. The two groups were well matched with regards to demographics and fracture type. The overall union rate was similar in both groups but the time to union was shorter in the TAN group. There were 8 implant failures in the PFNA (22.2%) group compare to none in the TAN group. Implant failure was associated with the severity of fracture (AO 31.A3.3) but was not related to fracture malreduction or screw position (Tip-apex-distance). Our study suggests that the use of reconstruction system with two screws such as TAN may be more suitable implant for reverse oblique intertrochanteric hip fractures. [ABSTRACT FROM AUTHOR]

Abstract: Background: In April 2004 the Israeli Ministry of Health decided to condition DRG payment for hip surgery by time between hospitalisation and operation, giving a fine for every day's delay beyond 48h. An evaluation study performed 2 years after the reform has shown the positive influence of the reform on patient's survival in the hospital. This study evaluates the impact of the reform on the longer-term mortality of patients. Methods: A retrospective study based on data from nine hospitals of the national trauma registry available for the years 2001–2007, with surveillance on 2-year survival through data of Ministry of the Interior. The study population includes patients aged 65 and above with an isolated hip fracture following trauma. Mortality curves and Cox regression were utilised to compare the influence of different parameters on long-term mortality. Results: Earlier surgery had a significant positive impact on survival through the whole length of the study period. In the period after the introduction of the new reimbursement system for hip fracture surgeries, a significant decrease in the longer-term mortality was observed up to 6 months of follow-up, even when adjusted by patients’ age, gender and the receiving hospital. After 6 months there was no further decrease in relative risk, though the survival advantage remained with patients hospitalised after the reform. Conclusions: The reform appears successful in decreasing the longer-term patient mortality after hip fracture through influencing surgical practice. [Copyright &y& Elsevier]

Abstract: Background: Hip fractures are always associated with a high postoperative mortality, the preoperative predictors for mortality have neither been well identified or summarised. This systematic review and meta-analysis was performed to identify the preoperative non-interventional predictors for mortality in hip fracture patients, especially focused on 1year mortality. Methods: Non-interventional studies were searched in Pubmed, Embase, Cochrane central database (all to February 26th, 2011). Only prospective studies and retrospective studies with prospective collected data were included. Qualities of included studies were assessed by a standardised scale previous reported for observational studies. The effects of individual studies were combined with the study quality score using a previous reported model of best-evidence synthesis. The hazard ratios of strong evidence predictors were combined only by high quality studies. Results: 75 included studies with 94 publications involving 64,316 patients were included and the available observations was a heterogeneous group. The overall inpatient or 1month mortality was 13.3%, 3–6months was 15.8%, 1year 24.5% and 2years 34.5%. There were strong evidence for 12 predictors, including advanced age, male gender, nursing home or facility residence, poor preoperative walking capacity, poor activities of daily living, higher ASA grading, poor mental state, multiple comorbidities, dementia or cognitive impairment, diabetes, cancer and cardiac disease. We also identified 7 moderate evidence and 12 limited evidence mortality predictors, and only the race was identified as the conflicting evidence predictor. Conclusion: Whilst there is no conclusive evidence of the preoperative predictors for mortality following hip fractures, special attention should be paid to the above 12 strong evidence predictors. Future researches were still needed to evaluate the effects of these predictors. [Copyright &y& Elsevier]

In this retrospective study, we looked at the difference in 1 year mortality between two groups of patients who were operated for fracture of the hip. Patients and methods: In cohort 1, 72% of the patients underwent surgery on the same day of admission, 15% of the patients were operated on the next day, the remaining 13% of the patients waited more than 1 day for surgery. The mean waiting time was 0.47 day. The percentage of patients who were operated on the same day of admission in cohort 2 was 18%. Sixty-nine percent of the patients had to wait 1 day before they were operated and 13% waited 2 days or more. The average waiting time was 1.01 days. The date of death for both the 166 patients in cohort 1 and the 197 patients in cohort 2, was obtained from the national mortality register and the 1 year mortality was calculated. These two groups of patients were from separate 12 month periods and the operations performed were either Dynamic Hip Screw (DHS) or hemiarthroplasty. The two groups were comparable in gender, age distribution and the types of operations. Results: There was an increase of 10.1% (P<0.025, χ2, 1 d.f.; 95% CI 1.7–18.5) in the mortality of patients in cohort 2. The mortality data of the two cohorts was also analysed after dividing the patients into three groups according to their age. A statistically significant increase in mortality of 16.9% in patients over 80 years of age in cohort 2 was found. The difference in mortality was still statistically significant when only patients over 80 years of age and having a DHS operation were compared. Total mortality at 2 years after the operation was the same in the two cohorts. Mortality rate for patients in cohort 2 was less than that for cohort 1 patients during the second post-operative year. Conclusion: This study shows that survival at 1 year is better when patients who are medically fit for surgery are operated on the same day of admission. This survival advantage is more pronounced for patients who are over 80 years of age. [Copyright &y& Elsevier]

This retrospective study evaluates the results obtained in five Italian departments of traumatology in the treatment of peritrochanteric (pertrochanteric and subtrochanteric) fractures by the intramedullary hip screw (IMHS; Smith & Nephew Richards, Memphis, TN, USA) nail. One thousand two hundred and seventy-three patients were treated with the IMHS nail between March 1992 and February 2000.The results of these operations were evaluated clinically and radiological in 981 patients. The 90.3% of patients could walk unaided or with simple support. Because of the low complication rate requiring re-operation (postoperative shaft fractures, screw penetrated the acetabulum, cut out and non-union) (1.7%), we think that this device is an advance in the treatment of peritrochanteric fractures.

Abstract: Introduction: Despite advances in surgical and anaesthetic techniques the mortality after hip fracture has not significantly changed in the last 40 years. Pre-operative anaemia is a risk factor for peri-operative death. We speculate that a significant proportion of the blood loss related to hip fractures has occurred prior to surgery. Identifying patients at risk of pre-operative anaemia can facilitate appropriate medical optimisation. This study is unique in its attempt to quantify the blood loss associated with the initial hip injury. Methods: In a retrospective study all patients with both a diagnosis of hip fracture and an operative delay of >48h were assessed. The information collected included: fracture classification, serial haemoglobins and patient co-morbidities. The exclusion criteria included a pre-injury diagnosis of anaemia, anti-coagulation and gastrointestinal bleeds. Results: Between 2007/2008 sixty-eight intracapsular and fifty extracapsular hip fracture patients had serial haemoglobins and operative delays of >48h (mean 75h, range 48–270h). The mean lowest recorded haemoglobin prior to surgery for both extracapsular and intracapsular fractures were 95.0g/L (±SEM 2.2) and 108.5g/L (±SEM 2.2) respectively. This difference was statistically significant (Student''s t-test p <0.05). The mean haemoglobin drop in the extracapsular and intracapsular fracture groups was 20.2g/L (range 0–49g/L) and 14.9g/L (range 0–59g/L) respectively. Conclusions: Hip fracture patients have a large drop in haemoglobin that is associated with the initial trauma rather than the operation. This highlights the need for anaesthetic and orthopaedic staff to be vigilant to the risk of pre-operative anaemia in this cohort of frail patients even when the initial haemoglobin is apparently normal.
