The Nottingham Hip Fracture Score (NHFS) was developed in 2007 as a predictor of 30-day mortality after hip fracture surgery following a neck of femur fracture. The National Hip Fracture Database is the standard used which calculated their own score using national data. The NHF score for 30-day mortality was calculated for 50 patients presenting with a fractured neck femur injury between January 2020 to March 2020. A score <5 was classified as low risk and >/=5 as high risk. Aim was to assess the accuracy in calculating the Nottingham Hip Fracture Score against the National Hip Fracture Database. To explore whether it should it be routinely included during initial assessment to aid clinical management?. There was an increase in the number of mortalities observed in patients who belonged to the high-risk group (>=5) compared to the low risk group. COVID-19 positive patients had worse outcomes with average 30-day mortality of 6.78 compared to the average of 6.06. GEH NHF score per month showed significant accuracy against the NHFD scores. The identification of high-risk groups from their NHF score can allow for targeted optimisations and elucidation of risk factors easily gathered at the point of hospitalisation. The NHFS is a valuable tool and useful predictor to stratify the risk of 30-day mortality and 1-year mortality after hip fracture surgery. Inclusion of the score should be considered as mandatory Trust policy for neck of femur fracture patients to aid clinical management and improve patient safety overall

Introduction. Most western countries have implemented fast-track hip fracture aiming at surgery within 24 hours, since the mortality rate hereafter rises markedly. In Greenland, it is not achievable to operate within 24 hours. Arctic people live in sparsely populated areas and Greenland's population is scattered along the vast coastline. All patients must be chartered to Nuuk by airplane which can take up till several days to weeks, due to logistics and the Arctic weather. This presents a challenge regarding adhering to western guidelines. The operative delay may be acceptable though, as it is the impression that the Greenlandic population survives and endures better than patients of western populations. However, as data are lacking, we aimed to describe mortality among hip fracture patients in Greenland taking frailty and comorbidities into account. Method. All patients with ICD-10 codes DS720, DS721 and DS722 from 2018-2022 were identified as 261 patients diagnosed with hip fractures. Variables including time of diagnosis, time to operation, reasons for delay, ASA-score, Charlson Comorbidity index, time of death, and other possible confounding variables were analyzed. Primary outcome was mortality rates at 30-day post-OP and 1-year post-OP. Results. The average time from fracture to operation was 91.4 hours. In the Danish Cohort (DC) 70,6 % of patient were operated within 24 hours. Overall, 30-day mortality was 9,9 %, and 1-year mortality was 29,4 %, compared to the DC with 10,8 % 30-day mortality and 28,3 % 1-year mortality. Multivariate regression was conducted, showing no statiscal significant increase in mortality, despite extended delay. Conclusion. With no increase in death, the authors find it justifiable that patients in Greenland endure longer delays than the western population. The influence on further adverse effects needs to be investigated as well as causes of survival, but perhaps the Arctic people unveil mechanisms for raised survival among other populations

Introduction. We aimed to study the rates of both surgical and medical complications associated with femoral diaphysis fracture fixation with intramedullary nailing including all fracture mechanisms. Additionally, we investigated whether the trauma energy has an impact on the complication risk. Method. In this retrospective cohort study, the health records of 491 patients with 503 femoral fractures, who underwent surgery between May 2007 and May 2022 in Tampere University Hospital, were reviewed. Patients who underwent a primary operation with a reamed rigid intramedullary nail for a diaphyseal femoral fracture and whose follow-ups were organized at the same hospital district, were included. Based on those criteria, 57.5% were included for analysis (279 patients with 289 fractures). The complications were then recorded by chart review. To investigate the impact of trauma energy on complication risk, we compared complication proportions in high- and low-energy groups and calculated odds ratios. Result. The crude percentage of 30-day mortality was 2.1% (6 of 289) based on information obtained from the patients’ records. The overall proportion of complications was 22.5%. The risk of any medical complication was 2.8%, whereas the risk of surgical complication was 19.8%. The risk of complications was nearly twice as high in high-energy fractures compared to low-energy fractures, with an odds ratio (OR) of 1.92, 95% CI 1.03-3.75. The risk of reoperations was significantly increased in high-energy traumas (OR 2.46, CI 1.25-5.24). Conclusion. This study reveals a 2.1% risk of thirdy-day mortality and a 22.5% risk of overall complications, predominantly of a surgical type. The complication risk, especially the risk of surgical complications, is higher among the patients with fractures caused by high-energy injury compared to low-energy fractures, highlighting the importance of timely identification of those complications for providing better postoperative care

Introduction. The concept of same-day discharge has garnered increasing significance within orthopedic surgery, particularly in hip and knee procedures. Despite initial concerns surrounding the absence of prolonged hospital care, a burgeoning body of evidence highlights numerous advantages associated with same-day discharge, ranging from mitigating in-hospital infections to offering substantial financial and psychosocial benefits for both patients and healthcare providers. In this study, we aim to scrutinize the trends in same-day discharge specifically within the realm of total hip arthroplasties. Method. This retrospective analysis delves into the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) database spanning from 2017 to 2021. Leveraging patient data sourced from the ACS NSQIP database, we sought to elucidate patterns and shifts in same-day discharge practices pertaining to total hip arthroplasties. Result. The preoperative analysis illuminated several notable disparities between patients undergoing same-day hip arthroplasty and those necessitating hospitalization. Notably, same-day hip patients skewed younger, comprising 48.3%females compared to 55.6% in hospitalized hip patients. Furthermore, a lower prevalence of medical comorbidities such as diabetes mellitus (8.5% vs.12.9%), current smoking (9.3% vs. 12.2%), and severe COPD(1.9% vs. 4.1%) was observed among same-day hip group. Operatively, same-day hip surgeries boasted shorter durations, averaging 83.9 minutes, in contrast to the 92.3minutes for hospitalized hip procedures. Postoperatively, same-day hip patients exhibited significantly diminished rates of 30-day readmissions (1.7%vs. 3.5%), procedure-related readmissions (1.0%vs.2.1%), reoperations (1.1%vs.1.9%), and mortality (0.02% vs. 0.04%). Moreover, the prevalence of the same-day discharge concept experienced a remarkable ascent from 2016 to 2021, with rates escalating from 1.5% to 25.6% of all total hip arthroplasties over a span of just six years. Conclusion. In conclusion, same-day discharge is a feasible and safe option for selected THA patients

Object. The aim of this study was to investigate the impact of the COVID-19 pandemic on the management and outcome of patients with neck of femur fractures. Methods. Data was collected for 96 patients with neck of femur fractures who presented to the emergency department between March 1, 2020 and May 15, 2020. This data set included information about their COVID-19 status. Parameters including inpatient complications, hospital quality measures, mortality rates, and training opportunities were compared between the COVID-19 positive and COVID-19 negative groups. Furthermore, our current cohort of patients were compared against a historical control group of 95 patients who presented with neck of femur fractures before the COVID-19 pandemic. Results. Seven (7.3%) patients were confirmed COVID positive by RT-PCR testing. The COVID positive cohort, when compared to the COVID negative cohort, had higher rates of postoperative complications (71.4% vs 25.9%), increased length of stay (30.3 days vs 12 days) and quicker time to surgery (0.7 days vs 1.3 days). The 2020 cohort compared to the 2019 cohort, had an increased 30-day mortality rate (13.5% vs 4.2%), increased number of delayed cases (25% vs 11.8%) as well as reduced training opportunities for Orthopaedic trainees to perform the surgery (51.6% vs 22.8%). Conclusions. COVID-19 has had a profound impact on the care and outcome of neck of femur fracture patients during the pandemic with an increase in 30-day mortality rate. There were profound adverse effects on patient management pathways and outcomes while also affecting training opportunities

Hip fractures are a common injury in elderly patients. The UK has a National Hip Fracture Database to collect data on all patients presenting to hospital with a hip fracture. Literature evidence suggests that early surgery for hip fracture patients improves morbidity and mortality. UK national guidelines (BOA, NICE) recommend that surgery is performed within 36 hours of presentation and/or diagnosis for inpatients. Best Practice Tariffs ensure that hospitals are paid a set value if they meet this target of surgery within 36 hours. This study aims to look at reasons for delay to surgery for patients presenting to our busy level 2 trauma unit. This is a retrospective review of prospectively collected data for patients referred to the orthopaedic team at our hospital with a diagnosis of a neck of femur fracture between 1st April and 31st December 2018. Patients under the age of 65 year of age were excluded from our study. Only patients who were operated on after 36 hours were included. The database for reasons of surgical delay was reviewed and electronic patient records were used to collect further data on length of stay and 30-day mortality. A total of 249 patients were diagnosed with a hip fracture during the study period. 2 patients were too unwell for an operation and died within 24 hours of diagnosis/admission. 46 patients were included in the study. The primary reasons for surgical delay were patients not being fit for surgery (14/46) and the use of anti-coagulation (14/46). Other reasons included a lack of surgical capacity (7/46) and delayed diagnosis due to further imaging (CT). Mean delay to surgery was 51.8 hours (range 34.5 – 157.2 hours; median 42.9 hours), mean length of stay 20.4 days (range 5.3 – 55.7 days, median 15.6 days). 30-day mortality was 4/46 (8.6%) for patients who were delayed. Many of the issues we found in this study are unusual however these problems are commonly faced in many level 2 trauma units that serve an ever growing ageing population. Changing practice to provide improved out-of-hours medical care to facilitate medical optimisation and using current literature evidence that shows that the use of DOACs/NOACs does not adversely affect outcomes when patients are operated on within 24 hours of the last dose may help improve times to surgery

Background. The Nottingham Hip Fracture Score (NHFS) is a risk stratifying score that estimates the 30-day and 12-month mortality rates of hip fracture patients. To date, it has only been validated in few centres in the UK. Our study aims to see how our mortality rates compare with those predicted by the NHFS. Methods. The Nottingham Hip Fracture Database was reviewed for patients presenting to our unit from August 2012 - March 2013 with a neck of femur fracture. Patient information was obtained from the database and our online electronic patient records for NHFS calculation. Patients with incomplete data were excluded. Results. 285 patients were identified, 11 were excluded. 69 (24%) were male. The average age was 82 years. The highest mortality was in those with a NHFS=9 (50%). The high-risk (NHFS≥5) patients had a higher mortality rate (n=19, 13%) compared to the low risk group (NHFS≤4) (n=7; 5%). Conclusions. Our study shows that most of our patients had a NHFS 4 – 6, which is comparable to other units. Mortality rates increased steeply from 5% to 16% from NHFS 5–6. A validation study of the NHFS showed that a score of greater than 6 was more closely correlated with high mortality. For NHFS=2, the mortality was 20%. The patient who died was a 48-year old female with breast cancer and 2 previous pulmonary emboli. The published co-morbidities for NHFS doesn't include PEs and may underestimate a patient's morbidity. Large-scale nationwide studies to determine the validity of the NHFS are needed.

Background. Patients suffering a distal femoral fracture are at a high risk of morbidity and mortality. Currently this cohort is not afforded the same resources as those with hip fractures. This study aims to compare their mortality rates and assess whether surgical intervention improves either outcome or mortality following distal femoral fractures. Methods. Patients over sixty-five admitted with a distal femoral fracture between June 2007 and 2012 were retrospectively identified. Patients mobility was categorised as unaided, walking aid, zimmer frame, or immobile. The 30-day, six-month, and one-year mortality rates were recorded for this group as well as for hip fractures during the same period. Results. 68 patients were included in the study. 85% of the patients were female and the mean age was 84 years. 8 patients (12%) had an underlying total knee arthroplasty. 43 patients (63%) were managed non-operatively and of those treated surgically 7 had plate fixation (28%) and 18 had intramedullary nailing (72%). The mortality rate for all patients with distal femoral fractures was 7% at 30 days, 26% at six months, and 38% at one year, higher than hip fractures during the same period by 8%, 13%, and 18%, respectively. Patients managed surgically had lower mortality rates and higher mobility levels. Conclusion. Patients suffering a distal femoral fracture have a high mortality rate and surgical intervention seems to improve both mobility and mortality. Currently this group of patients obtains less attention and resources than hip fracture patients. Further research assessing the impact of increasing resources on this group of patient is required.

Background. Frequency of primary total hip (THA) and total knee (TKA) arthroplasty procedures is increasing, with a subsequent rise in revision procedures. This study aims to describe timing and excess surgical mortality associated with revision THA and TKA compared to those on the waiting list. Methods. All patients from 2003–2013 in a single institution who underwent revision THA and TKA, or added to the waiting list for the same procedure were recorded. Mortality rates were calculated at cutoffs of 30- and 90-days post-operation or addition to the waiting list. Results. 561 and 547 patients were available for the survivorship analysis in the revision THA and TKA groups respectively. Following exclusion, 901 and 832 patients were available for the 30-day analysis and 484 and 568 patients for the 90-day analysis in the revision THA and revision TKA waiting list groups respectively. The 30- and 90-day mortality rate was significantly greater for the revision THA group compared to the waiting list group (excess surgical mortality of 0.357%, 95% confidence interval 0.098% to 0.866%; p=0.037) (odds ratio of 5.22, 95% confidence interval 0.626 to 43.524; excess surgical mortality of 0.863%, 95% confidence interval 0.455% to 1.153%; p=0.045). The 30- and 90-day mortality rate was not significantly greater for the revision TKA group compared to the waiting list group (excess surgical mortality of zero) (excess surgical mortality of 0.366%, 95% confidence interval 0.100% to 0.651%; p=0.075). Conclusions. Revision THA is associated with a significant excess surgical mortality rate at 30- and 90-days post operation when compared to the waiting list for the same procedure. However, we have been unable to quantify any increased risk after revision TKA. We would encourage other authors with access to larger samples to use our method to quantify excess mortality after revision TKA. Level of Evidence. III-Retrospective Cohort Study

Mesenchymal stem cells (MSCs) are self-renewing, multipotent cells that could potentially be used to repair injured cartilage in diseases. The objetive was to analyze different sources of human MSCs to find a suitable alternative source for the isolation of MSCs with high chondrogenic potential. Femoral bone marrow, adipose tissue from articular and subcutaneous locations (hip, knee, hand, ankle and elbow) were obtained from 35 patients who undewent different types of orthopedic surgery (21 women, mean age 69.83 ± 13.93 (range 38–91) years. Neoplasic and immunocompromised patients were refused. The Ethical Committee for Clinical Research of the Government of Aragón (CEICA) approved the study and all patients provided informed consent. Cells were conjugated wiith monoclonal antibodies. Cell fluorescence was evaluated by flow cytometry using a FACSCalibur flow cytometer and analysed using CellQuest software (Becton Dickinson). Chondrogenic differentiation of human MSCs from the various tissues at P1 and P3 was induced in a 30-day micropellet culture [Pittenger et al., 1999]. To evaluate the differentiation of cartilaginous pellet cultures, samples were fixed embedded in paraffin and cut into 5- υm-thick slices. The slices were treated with hematoxylin-eosin and safranin O (Sigma-Aldrich). Each sample was graded according to the Bern Histological Grading Scale [Grogan et al., 2006], which is a visual scale that incorporates three parameters indicative of cartilage quality: uniform and dark staining with safranin O, cell density or extent of matrix produced and cellular morphology (overall score 0–9). Stained sections were evaluated and graded by two different researchers under a BX41 dual viewer microscope or a Nikon TE2000-E inverted microscope with the NIS-Elements software. Statistics were calculated using bivariate analysis. Pearson's χ2 or Fisher's exact tests were used to compare the Bern Scores of various tissues. To evaluate the cell proliferation, surface marker expression and tissue type results, ANOVA or Kruskal-Wallis tests were used, depending on the data distribution. Results were considered to be significant when p was < 0.05. MSCs from all tissues analysed had a fibroblastic morphology, but their rates of proliferation varied. Subcutaneous fat derived MSCs proliferated faster than bone marrow. MSCs from Hoffa fat, hip and knee subcutaneous proliferated slower than MSCs from elbow, ankle and hand subcutaneous. Flow cytometry: most of cells lacked expression of CD31, CD34, CD36, CD117 (c-kit), CD133/1 and HLA-DR. At same time 95% of cells expressed CD13, CD44, CD59, CD73, CD90, CD105, CD151 y CD166. Fenotype showed no differences in cells from different anatomic places. Cells from hip and knee subcutaneous showed a worst differentiation to hyaline cartilage. Hoffa fat cells showed high capacity in transforming to hyaline cartilage. Cells from different anatomic places show different chondrogenic potential that has to be considered to choose the cells source

Recent National Institute for Health and Care Excellence (NICE) guidance has advised against the continued use of the Thompson implant when performing hip hemiarthroplasty and recommended surgeons consider using the anterolateral surgical approach over a posterior approach. Our objective was to review outcomes from a consecutive series of Thompson hip hemiarthroplasty procedures performed in our unit and to identify any factors predicting the risk of complications. 807 Thompson hip hemiarthroplasty cases performed between April 2008 and November 2013 were reviewed. 721 (89.3%) were cemented and 86 (10.7%) uncemented. 575 (71.3%) were performed in female patients. The anterolateral approach was performed in 753 (93.3%) and the posterior approach with enhanced soft tissue repair in 54 (6.7%). Overall, there were 23 dislocations (2.9%). Dislocation following the posterior approach occurred in 13.0% (7 of 54) in comparison to 2.1% (16 of 753) with the anterolateral approach (odds ratio (OR) 8.5 (95% CI 2.8 to 26.3) p < 0.001). Surgeon grade and patient history of cognitive impairment did not have a significant impact on dislocation rate. Patients were discharged home in 459 cases (56.9%), to a care home or other hospital in 273 cases (33.8%). 51.8% (338 of 653) returned home within 30 days. 75 died during their admission (9.3%). 30-day mortality was 7.1% and 1-year mortality was 16.6%. Intraoperative fracture occurred in 15 cases (1.9%) of which 14 were cemented. Superficial or deep infection occurred in 33 cases (4.1%). We recommend against the continued use of the posterior approach in hip hemiarthroplasty, as enhanced soft tissue repair did not reduce dislocation rates to an acceptable level. Our findings, however, demonstrate satisfactory results for patients treated with the Thompson hip hemiarthroplasty performed through an anterolateral approach. We suggest that the continued use of the Thompson implant in a carefully selected patient cohort is justifiable

Objectives

We have increased the dose of tranexamic acid (TXA) in our enhanced total joint recovery protocol at our institution from 15 mg/kg to 30 mg/kg (maximum 2.5 g) as a single, intravenous (IV) dose. We report the clinical effect of this dosage change.

Objectives

Recent studies have shown that modulating inflammation-related lipid signalling after a bone fracture can accelerate healing in animal models. Specifically, decreasing 5-lipoxygenase (5-LO) activity during fracture healing increases cyclooxygenase-2 (COX-2) expression in the fracture callus, accelerates chondrogenesis and decreases healing time. In this study, we test the hypothesis that 5-LO inhibition will increase direct osteogenesis.
