There has been extensive discussion about the effect of delay to surgery on mortality in patients sustaining a fracture of the hip. Despite the low level of evidence provided by many studies, a consensus has been accepted that delay of > 48 hours is detrimental to survival. The aim of this prospective observational study was to determine if early surgery confers a survival benefit at 30 days.

Between 1989 and 2013, data were prospectively collected on patients sustaining a fracture of the hip at Peterborough City Hospital. They were divided into groups according to the time interval between admission and surgery. These thresholds ranged from <  6 hours to between 49 and 72 hours. The outcome which was assessed was the 30-day mortality. Adjustment for confounders was performed using multivariate binary logistic regression analysis. In all, 6638 patients aged > 60 years were included.

Worsening American Society of Anaesthesiologists grade (p < 0.001), increased age (p <  0.001) and extracapsular fracture (p < 0.019) increased the risk of 30-day mortality.

Increasing mobility score (p = 0.014), mini mental test score (p < 0.001) and female gender (p = 0.014) improved survival. After adjusting for these confounders, surgery before 12 hours improved survival compared with surgery after 12 hours (p = 0.013). Beyond this the increasing delay to surgery did not significantly affect the 30-day mortality.

This international multicentre retrospective cohort study aimed to assess: 1) prevalence of COVID-19 in hip fracture patients, 2) effect on mortality, and 3) clinical factors associated mortality among COVID-19-positive patients. A collaboration among 112 centres in 14 nations collected data on all patients with a hip fracture between 1st March-31st May 2020. Patient, injury and surgical factors were recorded, and outcome measures included admission duration, COVID-19 and 30-day mortality status. There were 7090 patients and 651 (9.2%) were COVID-19-positive. COVID-19 was independently associated with male sex (p=0.001), residential care (p<0.001), inpatient fall (p=0.003), cancer (p=0.009), ASA grade 4–5 (p=0.008; p<0.001), and longer admission (p<0.001). Patients with COVID-19 had a significantly lower chance of 30-day survival versus those without (72.7% versus 92.6%, p<0.001), and COVID-19 was independently associated with increased 30-day mortality risk (p<0.001). Increasing age (p=0.028), male sex (p<0.001), renal (p=0.017) and pulmonary disease (p=0·039) were independently associated with higher 30-day mortality risk in patients with COVID-19 when adjusting for confounders. The prevalence of COVID-19 in hip fracture patients was 9% and was independently associated with a three-fold increased 30-day mortality risk. Clinical factors associated with mortality among COVID-19-positive hip fracture patients were identified for the first time. This is the largest study, and the only global cohort, reporting on the effect of COVID-19 in hip fracture patients. The findings provide a benchmark against which to determine vaccine efficacy in this vulnerable population and are especially important in the context of incomplete vaccination programmes and the emergence of vaccine-resistant strains

The aims were: (1) assess the influence of COVID-19 on mortality in hip fracture; (2) identify predictors of COVID-19 status, and (3) investigate whether social lockdown influenced the epidemiology of hip fracture. A multicentre retrospective study was conducted of all patients presenting to six hospitals with hip fracture over a 46-day period (23 days pre-/post-lockdown). Demographics, residence, place of injury, presentation blood tests, Nottingham Hip Fracture Score, time to surgery, operation, ASA grade, anaesthetic, length of stay, COVID-19 status, and 30-day mortality were recorded. Of 317 patients with hip fracture 27 (8.5%) had a positive COVID-19 test; only 7 (26%) had symptoms on admission. COVID-19-positive patients had significantly lower 30-day survival compared to those without COVID-19 (67% versus 92%, p<0.001). COVID-19 was independently associated with increased 30-day mortality adjusting for: (1) age, sex, residence (HR 2.93, p=0.008); (2) Nottingham Hip Fracture Score (HR 3.52, p=0.001), and (3) ASA (HR 3.45, p=0.004). Platelet count predicted subsequent COVID-19 status; a value <217 ×109/L was 68% specific and sensitive (95% CI 58 to 77, p=0.002). A similar number of patients presented with hip fracture pre-lockdown (n=160) and post-lockdown (n=157); there was no significant difference in demographics, place of injury, Nottingham Hip Fracture Score, time to surgery, ASA, or management. COVID-19 was independently associated with an increased 30-day mortality in hip fracture. Most patients with COVID-19 lacked suggestive symptoms at presentation. Platelet count was an indicator of risk of COVID-19 infection. These findings have urgent implications for the delivery of hip fracture services

Introduction. The purpose of this study was to compare the clinical outcomes and complications following bilateral simultaneous total knee arthroplasty in high body mass index (BMI) patients(>30kg/m. 2. ) to those of patients with a BMI<30 kg/m. 2. . Materials and Methods. Using data from an academic arthroplasty database and review of clinic charts we obtained health related quality of life (SF-12), and disease specific functional outcome scores (WOMAC or Oxford Knee Score). We also assessed length of hospital stay, ASA grade and transfusion requirements. Sixty six patients had a BMI<30 and 151 patients had a BMI>30. Results. Most cases were performed under combined spinal/epidural anaesthesia. We could find no appreciable difference in length of hospital stay, ASA grade or transfusion requirements between the two subgroups. Furthermore, were unable to detect any significant differences in post operative SF-12, WOMAC or Oxford Knee scores. There appeared to be no significant increase in the rate of medical complications between the two subgroups, and while there may have been a slight trend towards higher procedure related complications in the high BMI group, this did not reach statistical significance. Conclusions. In our study increased BMI appears to have no negative effects as regards functional outcomes, hospital stay or transfusion requirements for bilateral sequential knee arthroplasty. However there may be an increase in procedural/device related complications which could result in increased revision rates in these patients

United Kingdom National Institute for Health and Clinical Excellence guidelines recommend the use of total hip replacement (THR) for displaced intracapsular fractures of the femoral neck in cognitively intact patients, who were independently mobile prior to the injury. This study aimed to analyse the risk factors associated with revision of the implant and mortality following THR, and to quantify risk. National Joint Registry data recording a THR performed for acute fracture of the femoral neck between 2003 and 2010 were analysed. Cox proportional hazards models were used to investigate the extent to which risk of revision was related to specific covariates. Multivariable logistic regression was used to analyse factors affecting peri-operative mortality (< 90 days). A total of 4323 procedures were studied. There were 80 patients who had undergone revision surgery at the time of censoring (five-year revision rate 3.25%, 95% confidence interval 2.44 to 4.07) and 137 patients (3.2%) patients died within 90 days. After adjusting for patient and surgeon characteristics, an increased risk of revision was associated with the use of cementless prostheses compared with cemented (hazard ratio (HR) 1.33, p = 0.021). Revision was independent of bearing surface and head size. The risk of mortality within 90 days was significantly increased with higher American Society of Anesthesiologists (ASA) grade (grade 3: odds ratio (OR) 4.04, p < 0.001; grade 4/5: OR 20.26, p < 0.001; both compared with grades 1/2) and older age (≥ 75 years: OR 1.65, p = 0.025), but reduced over the study period (9% relative risk reduction per year). THR is a good option in patients aged < 75 years and with ASA 1/2. Cementation of the femoral component does not adversely affect peri-operative mortality but improves survival of the implant in the mid-term when compared with cementless femoral components. There are no benefits of using head sizes > 28 mm or bearings other than metal-on-polyethylene. More research is required to determine the benefits of THR over hemiarthroplasty in older patients and those with ASA grades > 2

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

Aims

This study aimed to compare mortality in trochanteric AO/OTA A1 and A2 fractures treated with an intramedullary nail (IMN) or sliding hip screw (SHS). The primary endpoint was 30-day mortality, with secondary endpoints at 0 to 1, 2 to 7, 8 to 30, 90, and 365 days.

Aims

The aims of this study were to assess quality of life after hip fractures, to characterize respondents to patient-reported outcome measures (PROMs), and to describe the recovery trajectory of hip fracture patients.

Aims

Factors associated with high mortality rates in geriatric hip fracture patients are frequently unmodifiable. Time to surgery, however, might be a modifiable factor of interest to optimize clinical outcomes after hip fracture surgery. This study aims to determine the influence of postponement of surgery due to non-medical reasons on clinical outcomes in acute hip fracture surgery.

Limb reconstruction requires high levels of patient compliance and impacts heavily on social circumstances. The epidemiology and socioeconomic description of trauma patients has been well documented, however no study has assessed the epidemiology of limb reconstruction patients. The aim of this project is to describe patients attending Limb Reconstruction Services (LRS) in order to highlight and address the social implications of their care. All LRS cases under a single surgeon in a district general hospital were included from 2010 – 2016. Demographics, ASA grade, smoking status, mental health status and employment status were collated. Postcode was converted into an Index of Multiple Deprivation score using GeoConvert® software. Patient socioeconomic status was then ranked into national deprivation score quintiles (quintile 1 is most affluent, quintile 5 is most deprived). Deprivation scores were adjusted by census data and analysed with Student's T-test. The distance from the patient's residence to the hospital was generated through AA route planner®. Patient attendance at clinic and elective or emergency admissions was also assessed. Patient outcomes were not part of this research. There were 53 patients, of which 66% (n=35) were male, with a mean age of 45 years (range 21–89 years). Most patients were smokers (55%, n=29), 83% (n=42) were ASA 1 or 2 (there were no ASA 4 patients). The majority of indications were for acute trauma (49%), chronic complications of trauma (32%), congenital deformity (15%) and salvage fusion (4%). Mental health issues affected 23% (n=12) of cases and 57% of working-aged patients were unemployed. Mental health patients had a higher rate of trauma as an indication than the rest of the cohort (93% vs. 76%). Deprivation quintiles identified that LRS patients were more deprived (63% in quintiles 4 and 5 vs. 12% of 1 and 2), but this failed to reach statistical significance (p=0.9359). The mean distance from residence to hospital was 12 miles (range 0.35–105 miles, median 7 miles). The patients derived from a large region made up of 12 local authorities. There was a mean of 17 individual LRS clinic attendances per patient (range: 3–42). Cumulative distance travelled for each patient during LRS treatment was a mean of 495 miles (range 28 – 2008 miles). The total distance travelled for all 53 patients was over 26,000 miles. The results largely mirror the findings of trauma demographic and socioeconomic epidemiology, due to the majority of LRS indications being post-traumatic in this series. The high rates of unemployment and mental health problems may be a risk factor for requiring LRS management, or may be a product of the treatment. Clinicians may want to consider a social care strategy alongside their surgical strategy and fully utilise their broader MDT to address the social inequalities in these patients. This strategy should include a mental health assessment, smoking cessation therapy, sign-posted support for employment circumstances and a plan for travel to the hospital. The utilisation and cost of ambulance services was not possible with this methodology. Further work should prospectively assess the changes in housing circumstances, community healthcare needs and whether there was a return to employment and independent ambulation at the end of treatment

Radiation exposure is a hazard to orthopaedic surgeons, theatre staff and patients intra-operatively. Obesity is becoming a more prevalent problem worldwide and there is little evidence how a patient's body habitus correlates with the radiation doses required to penetrate the soft tissues for adequate imaging. We aimed to identify if there was a correlation between Body Mass Index (BMI) and radiation exposure intra-operatively. We performed a retrospective review of 75 patients who underwent sliding hip screw fixation for femoral neck fractures in one year. We recorded Body Mass Index (BMI), screening time, dose area product (DAP), American Society of Anesthesiologists (ASA) grade, seniority of surgeon and complexity of the fracture configuration. We analysed the data using statistical tests. We found that there was a statistically significant correlation between dose area product and patient's BMI. There was no statistically significant relationship between screening time and BMI. There was no statistical difference between ASA grade, seniority of surgeon, or complexity of fracture configuration and dose area product. Obese patients are exposed to increased doses of radiation regardless of length of screening time. Surgeons and theatre staff should be aware of the increased radiation exposure during fixation of fractures in obese patients and, along with radiographers, ensure steps are taken to minimise these risks

Aims

The Peri-Implant and PeriProsthetic Survival AnalysiS (PIPPAS) study aimed to investigate the risk factors for one-year mortality of femoral peri-implant fractures (FPIFs).

Aims

To determine if patient ethnicity among patients with a hip fracture influences the type of fracture, surgical care, and outcome.

Aims

This study aimed to describe practice variation in the use of total hip arthroplasty (THA) for older patients with femoral neck fracture and to determine the association between patient, surgeon, and institution factors and treatment with THA.

We report a retrospective review of outcome after shoulder hemiarthroplasty for proximal humerus fractures. All patients managed with shoulder hemiarthroplasty for proximal humerus fractures between 1997 and 2008 were included. Clinical notes were reviewed and surviving patients completed postal Oxford Shoulder Score (OSS) questionnaires. Results were analysed to assess whether there was a difference in outcome for those above the age of 70 years. A total of 96 patients were treated during this period. Female to male ratio was 3.36:1 with mean age 72 ± 9.6 (45–93) years at time of fracture. At time of review 30.2% of patients were dead. Two patients were lost to follow-up after discharge. Complete case notes were available in 68 patients. Response rate to the OSS was 67.2%. There were 20 patients below 70 years and 48 patients above 70 years of age. The ASA grade was II in 60% of patients. Mean follow-up was 52 months. There were 2 in hospital post-operative deaths due to medical complications. Mean OSS was 27 (3–47) of a maximum of 48, with no significant difference between groups. Overall complication rate was 27.9%, with no significant difference between groups. Ten year survival was 96.9% overall with no significant difference between groups. There appears to be no significant difference in functional outcome, complication rate, or implant survival between patients below or above the age of 70 years treated with primary hemiarthroplasty for fracture of the proximal humerus. This procedure however carries a high complication rate in this group of patients

Aims

The aim of this study was to report the three-year follow-up for a series of 400 patients with a displaced intracapsular fracture of the hip, who were randomized to be treated with either a cemented polished tapered hemiarthroplasty or an uncemented hydroxyapatite-coated hemiarthroplasty.

Aims

Femoral periprosthetic fractures are rising in incidence. Their management is complex and carries a high associated mortality. Unlike native hip fractures, there are no guidelines advising on time to theatre in this group. We aim to determine whether delaying surgical intervention influences morbidity or mortality in femoral periprosthetic fractures.

Introduction. Femoral neck fractures are an increasingly common injury in the elderly. Frequently these patients present taking Clopidogrel, an irreversible inhibitor of platelet aggregation. Although this is associated with an increased risk of intra-operative bleeding and also an increased risk of spinal haematoma where regional anaesthesia is employed, the recent SIGN (Scottish Intercollegiate Guidance Network) guidelines recommend that surgery should not be delayed. Methods. We conducted a retrospective review of consecutive patients admitted with femoral neck fractures between April 2008 and October 2009. Patients on Clopidogrel were identified and data including ASA grade, time to operation, medical co-morbidities, and post-admission complications were recorded. Comparative information from the National Hip Fracture Database was used. Results. 405 patients were included. 27 patients were taking Clopidogrel on admission and they were mainly ASA 3 or 4. Mean time to theatre was 8 days. Post-admission medical complications occurred in 7 patients (25.9%). A further 4 patients (14.8%) died, 3 of them postoperatively. From the study population a control group of 72 ASA 3 and 4 patients was further studied. The mean time to operation was 2.3 days. Post-admission medical complications occurred in 13 patients (18%) and 8 patients (11%) died postoperatively. In 2009 the national mean time to operation was 2.19 days with an associated mortality rate of 8.67%. Discussion and Conclusion. Patients receiving Clopidogrel have complex medical co-morbidities and a higher anaesthetic risk. Delaying operative management might be contributing to the increased rate of mortality and morbidity. In accordance with the SIGN guidelines we recommend early operative intervention in these high risk patients

This paper describes an audit loop. We studied patients undergoing hip and knee surgery (arthroplasty and revision arthroplasty). All the patients were ‘complex elective’. I.e. they were either ASA grade 3 or 4, or had a body mass index in excess of 40. We collected data concerning postoperative admissions to HDU, ICU and PACU (planned and unplanned rates of admission, length of stay). We also noted mortality. In the first part of the study (April 2005 to March 2006) we studied 298 patients. All patients were assessed independently by an anaesthetist on the day of surgery. A multidisciplinary preoperative assessment clinic commenced in April 2006. After this date all patients were assessed preoperatively by a multidisciplinary anaesthetic lead team (anaesthetist, orthopaedic senior house officer, nurse practitioner). The need for an HDU or ICU bed was assessed and the bed was booked at part of the pre-operative plan. In the second part of the study (May 2006 to April 2009) a further 1147 arthroplasty patients were studied. Data was again collected regarding HDU, ICU, PACU and mortality as noted above. We found statistically significant (p=0.001) reductions in the admissions to PACU (22% down to 10%) and in mortality (6.1% down to 1.2%) after the introduction of the pre assessment clinic. There was also statistically significant (p=0.01) reduction in the HDU length of stay(2.1 days to 1.6 days), ITU unplanned admissions (1.3% to 0.4%) and the ITU length of stay in days (2.3 to 1.9 days). We also estimated cost savings of nearly £50 000 in the second limb of the study. This is based on the average decrease in HDU and ICU length of stay. We recommend the use of a multidisciplinary pre assessment clinic for complex orthopaedic surgery

Aims

This study aimed to identify risk factors (patient, healthcare system, and socioeconomic) for mortality after hip fractures and estimate their relative importance. Further, we aimed to elucidate mortality and survival patterns following fractures and the duration of excess mortality.
