Aims. Cemented hemiarthroplasty is an effective form of treatment for most patients with an intracapsular fracture of the hip. However, it remains unclear whether there are subgroups of patients who may benefit from the alternative operation of a modern uncemented hemiarthroplasty – the aim of this study was to investigate this issue. Knowledge about the heterogeneity of treatment effects is important for surgeons in order to target operations towards specific subgroups who would benefit the most. Methods. We used causal forest analysis to compare subgroup- and individual-level treatment effects between cemented and modern uncemented hemiarthroplasty in patients aged > 60 years with an intracapsular fracture of the hip, using data from the World Hip Trauma Evaluation 5 (WHiTE 5) multicentre randomized clinical trial. EuroQol five-dimension index scores were used to measure health-related quality of life at one, four, and 12 months postoperatively. Results. Our analysis revealed a complex landscape of responses to the use of a cemented hemiarthroplasty in the 12 months after surgery. There was heterogeneity of effects with regard to baseline characteristics, including age, pre-injury health status, and lifestyle factors such as alcohol consumption. This heterogeneity was greater at the one-month mark than at subsequent follow-up timepoints, with particular regard to subgroups based on age. However, for all subgroups, the effect estimates for quality of life lay within the confidence intervals derived from the analysis of all patients. Conclusion. The use of a cemented hemiarthroplasty is expected to increase health-related quality of life compared with modern uncemented hemiarthroplasty for all subgroups of patients aged > 60 years with a displaced intracapsular fracture of the hip.

Introduction. Following National patient safety alert on cement use in hip fracture surgery, we investigated the incidence and pattern of 72 hours peri-operative mortality after hip fracture surgery in a District General Hospital. Methods. We reviewed all patients who had hip fracture surgery between 2005-April, 2010. We recorded demographic variables, type of fracture, implant used, medical co-morbidity, seniority of operating surgeon and anaesthetist, peri-operative haemodynamic status, time and cause of death. Results. Over a 64 month period 15 cases were identified. Peri-operative death (PAD) was 1% (15/1402). 4/15 patients died intra-operatively. PAD was highest following Exeter Trauma Stem (ETS) implantation (5/85, 6%) and nil following Bipolar arthroplasty, Austin-Moore arthroplasty (AMA) or Cannulated screw fixation. PAD following total hip arthroplasty was 4% (1/25), Thompson's hemi-arthroplasty 2% (3/191), and Dynamic Hip Screw fixation 1% (6/695). Overall mortality after cemented implant was 2%. ETS implantation led to significantly increased peri-operative mortality compared to AMA (p=0.004). Operations were performed by both trainees (12) and Consultants (3). Both trainees (9) and Consultants (6) anaesthetised the patients. None of the patients belonged to ASA I or II (ASA III 6 and IV 9). All patients had significant cardio-vascular or pulmonary co-morbidity (Ca Lung 2, pulmonary fibrosis 1, end stage COAD 1, AF 6). Cemented implant insertion was followed by immediate haemodynamic collapse and death in 4/15, intra-operative haemodynamic instability in 1/15 and peri-operative instability in 5/15. Post-mortem was performed in 5/15: 2/5 were Pulmonary Embolism (PE), 2/5 bronchopneumonia and 1/5 Myocardial infarction (MI). 4/15 had suspected MI and 1/15 suspected PE. Conclusion. There was 1% risk of peri-operative death after hip fracture surgery. This risk was increased following cemented hemiarthroplasty and highest after ETS implantation. Risk was exacerbated in patients with pre-existing cardiovascular morbidity and independent of the seniority of the surgeon or the anaesthetist

Aim

This paper describes the methods applied to assess the cost-effectiveness of cemented versus uncemented hemiarthroplasty among hip fracture patients in the World Hip Trauma Evaluation Five (WHiTE5) trial.

Recent registry data from around the world has strongly suggested that using cemented hip hemiarthroplasty has lower revision rates compared to cementless hip hemiarthroplasty for acute femoral neck hip fractures. The adoption of using cemented hemiarthroplasty for hip fracture has been slow as many surgeons continue to use uncemented stems. One of the reasons is that surgeons feel more comfortable with uncemented hemiarthroplasty as they have used it routinely. The purpose of this study is to compare the difference in revision rates of cemented and cementless hemiarthroplasty and stratify the risk by surgeon experience. By using a surgeons annual volume of Total Hip Replacements performed as an indicator for surgeon experience. The Canadian Joint Replacement Registry Database was used to collect and compare the outcomes to report on the revision rates based on surgeon volume. This is a large Canadian Registry Study where 68447 patients were identified for having a hip hemiarthroplasty from 2012-2020. This is a retrospective cohort study, identifying patients that had cementless or cemented hip hemiarthroplasty. The surgeons who performed the procedures were linked to the procedure Total Hip Replacement. Individuals were categorized as experienced hip surgeons or not based on whether they performed 50 hip replacements a year. Identifying high volume surgeon (>50 cases/year) and low volume (<50 cases/year) surgeons. Hazard ratios adjusted for age and sex were performed for risk of revision over this 8-year span. A p-value <0.05 was deemed significant. For high volume surgeons, cementless fixation had a higher revision risk than cemented fixation, HR 1.29 (1.05-1.56), p=0.017. This pattern was similar for low volume surgeons, with cementless fixation having a higher revision risk than cemented fixation, HR 1.37 (1.11-1.70) p=0.004 We could not detect a difference in revision risk for cemented fixation between low volume and high volume surgeons; at 0-1.5 years the HR was 0.96 (0.72-1.28) p=0.786, and at 1.5+ years the HR was 1.61 (0.83-3.11) p=0.159. Similarly, we could not detect a difference in revision risk for cementless fixation between low volume and high volume surgeons, HR 1.11 (0.96-1.29) p=0.161. Using large registry data, cemented hip hemiarthroplasty has a significant lower revision rate than the use of cementless stems even when surgeons are stratified to high and low volume. Low volume surgeons who use uncemented prostheses have the highest rate of revision. The low volume hip surgeon who cements has a lower revision rate than the high volume cementless surgeon. The results of this study should help to guide surgeons that no matter the level of experience, using a cemented hip hemiarthroplasty for acute femoral neck fracture is the safest option. That high volume surgeons who perform cementless hemiarthroplasty are not immune to having revisions due to their technique. Increased training and education should be offered to surgeons to improve comfort when using this technique

Aims. Patients receiving cemented hemiarthroplasties after hip fracture have a significant risk of deep surgical site infection (SSI). Standard UK practice to minimize the risk of SSI includes the use of antibiotic-loaded bone cement with no consensus regarding type, dose, or antibiotic content of the cement. This is the protocol for a randomized clinical trial to investigate the clinical and cost-effectiveness of high dose dual antibiotic-loaded cement in comparison to low dose single antibiotic-loaded cement in patients 60 years and over receiving a cemented hemiarthroplasty for an intracapsular hip fracture. Methods. The WHiTE 8 Copal Or Palacos Antibiotic Loaded bone cement trial (WHiTE 8 COPAL) is a multicentre, multi-surgeon, parallel, two-arm, randomized clinical trial. The pragmatic study will be embedded in the World Hip Trauma Evaluation (WHiTE) (ISRCTN 63982700). Participants, including those that lack capacity, will be allocated on a 1:1 basis stratified by recruitment centre to either a low dose single antibiotic-loaded bone cement or a high dose dual antibiotic-loaded bone cement. The primary analysis will compare the differences in deep SSI rate as defined by the Centers for Disease Control and Prevention within 90 days of surgery via medical record review and patient self-reported questionnaires. Secondary outcomes include UK Core Outcome Set for hip fractures, complications, rate of antibiotic prescription, resistance patterns of deep SSI, and resource use (more specifically, cost-effectiveness) up to four months post-randomization. A minimum of 4,920 patients will be recruited to obtain 90% power to detect an absolute difference of 1.5% in the rate of deep SSI at 90 days for the expected 3% deep SSI rate in the control group. Conclusion. The results of this trial will provide evidence regarding clinical and cost-effectiveness between low dose single and high dose dual antibiotic-loaded bone cement, which will inform policy and practice guidelines such as the National Institute for Health and Care Excellence guidance on management of hip fractures.

The aim of this study was to analyze and compare clinical, radiological and mortality outcomes of patients who underwent cemented hip hemiarthroplasty for displaced neck of femur fractures using a SPAIRE technique when compared to a pair-matched control cohort who underwent the same procedure using the direct lateral approach. A retrospective review of patients who underwent cemented hip hemiarthroplasty for displaced neck of femur fractures by a single surgeon using a SPAIRE technique over a two-year period between July 2019 and July 2021 was performed. These were subsequently pair matched in a 5:1 ratio for age, gender, ASA grade and residential status with a control group who underwent cemented hip hemiarthroplasty by 4 other surgeons using a direct lateral approach. The study included a total of 240 patients (40 and 200 pairmatched to SPAIRE and control groups respectively), with a mean age of 81.0 ± 8.2 years (63–99) and a mean follow-up of 12 ± 3 months (3–30). Overall, there was no significant difference in any of the radiological or mortality outcome scores assessed between the SPAIRE and control groups (p > 0.05 for all). There was a significantly lower number of patients in the SPAIRE group who dropped a level of mobility from their pre-injury baseline at 30-days post-operatively (8.1% versus 31.6%; p = 0.003). However, this appeared to have resolved at 120-day follow-up with no significant differences between the groups in terms of those acquiring a new baseline mobility at 120-days post-operatively (2.7% versus 13.2%, p = 0.09). In cases of cemented hip hemiarthroplasty for displaced intracapsular neck of femur fractures, the SPAIRE technique appears to offer patients an earlier return to levels of baseline pre-injury mobility when compared to a direct lateral approach

Periprosthetic joint infection (PJI) in geriatric and/or multimorbid patients is an enormous challenge for orthopaedic surgeons. Revision procedures have also been demonstrated to expose patients to higher infection risks. Prior patient stratification according to presumed infection risks, followed by a more potent local antibiotic prophylaxis protocol with selective use of DALBC, is an interesting strategy to decrease the burden of PJI in high risk patients. The PubMed & EMBASE databases were screened for publications pertaining to the utilization of DALBC in cement for infection prophylaxis & prosthesis fixation. 6 preclinical & 7 clinical studies were identified which met the inclusion criteria and were stratified by level of clinical evidence. Only those studies were considered which compared the PJI outcome in the DALBC vs the SALBC group. (1). DALBC have been shown to exert a much stronger and longer lasting inhibition of biofilm formation on many PJI relevant bacteria (gram-positive and gram-negative pathogens) than single gentamicin-only containing cements. (2). DALBC use (COPAL G+C) in the intervention arm of 7 clinical studies has led to a significant reduction of PJI cases in a) cemented hemiarthroplasty procedures (3 studies, evidence level I and III), in b) cemented septic revision surgeries (2 studies, evidence level III), in c) cemented aseptic knee revisions (1 study, evidence level III) and in d) cemented primary arthroplasties in multi-morbid patients (1 study, evidence level III-IV). These benefits were not associated with more systemic side effects or a higher prevalence of broad antimicrobial resistancies. Use of DALBC is likely to be more effective in preventing PJI in high risk patients. The preliminar findings so far may encourage clinicians to consolidate this hypothesis on a wider clinical range

Aims. The aims of this study were to evaluate the incidence of reoperation (all cause and specifically for periprosthetic femoral fracture (PFF)) and mortality, and associated risk factors, following a hemiarthroplasty incorporating a cemented collarless polished taper slip stem (PTS) for management of an intracapsular hip fracture. Methods. This retrospective study included hip fracture patients aged 50 years and older treated with Exeter (PTS) bipolar hemiarthroplasty between 2019 and 2022. Patient demographics, place of domicile, fracture type, delirium status, American Society of Anesthesiologists (ASA) grade, length of stay, and mortality were collected. Reoperation and mortality were recorded up to a median follow-up of 29.5 months (interquartile range 12 to 51.4). Cox regression was performed to evaluate independent risk factors associated with reoperation and mortality. Results. The cohort consisted of 1,619 patients with a mean age of 82.2 years (50 to 104), of whom 1,100 (67.9%) were female. In total, 29 patients (1.8%) underwent a reoperation; 12 patients (0.7%) sustained a PFF during the observation period (United Classification System (UCS)-A n = 2; UCS-B n = 5; UCS-C n = 5), of whom ten underwent surgical management. Perioperative delirium was independently associated with the occurrence of PFF (hazard ratio (HR) 5.92; p = 0.013) and surgery for UCS-B PFF (HR 21.7; p = 0.022). Neither all-cause reoperation nor PFF-related surgery was independently associated with mortality (HR 0.66; p = 0.217 and HR 0.38; p = 0.170, respectively). Perioperative delirium, male sex, older age, higher ASA grade, and pre-fracture residential status were independently associated with increased mortality risk following hemiarthroplasty (p < 0.001). Conclusion. The cumulative incidence of PFF at four years was 1.1% in elderly patients following cemented PTS hemiarthroplasty for a hip fracture. Perioperative delirium was independently associated with a PFF. However, reoperation for PPF was not independently associated with patient mortality after adjusting for patient-specific factors.

Over 70,000 hip fractures occur annually in the UK. Both SIGN (111) and NICE (124) give guidance on optimal management of these patients. Both suggest cemented hemiarthroplasty should be used in those without contra-indications, as cemented implants are associated with less thigh pain, subsidence and a better functional outcome. Cardiorespiratory compromise secondary to bone cement implantation syndrome (BCIS) is however a concern in those with pre-existing cardiorespiratory disease (NYHA grade 3–4, pulmonary hypertension) or pathological fracture [3]. The aim of our study was to audit the practice of a University of Glasgow hospital with regard to cemented hemiarthroplasty. We retrospectively reviewed data on all patients treated with hemiarthroplasty for hip fracture at the Southern General Hospital between 01/01/12-02/04/12. Patient demographics, pre-operative plan, procedure performed, ASA grade and pre-morbid mobility were recorded. Results. Twenty-three hemiarthroplasties were performed. The median age was 82 (70–101). No patient aged over 90 underwent cemented hemiarthroplasty. Cemented implants (JRI, Furlong) were used in 26% (n=6) while 74% (n=17) underwent uncemented (Stryker, Austin-Moore) hemiarthroplasty. ASA grade was recorded in eight (35%). There were four ASA-2 patients (mild systemic disease not limiting activity) of which 75% underwent uncemented hemiarthroplasty. Pre-morbid mobility was recorded in eight (35%). All three independently mobile patients underwent uncemented hemiarthroplasty. Six (26%) had a documented pre-operative plan with regards to cement use. This study highlights the disparity between current recommendations and our Centres’ practice. Most notable were: poor recording of pre-operative mobility, poor documentation of a pre-operative surgical plan, the low use of cemented fixation even in fit mobile patients and the lack of ASA grade recording (stratification of risk) by our anaesthetic colleagues. We suggest a documented pre-operative discussion between the surgeon and anaesthetist to establish BCIS risk and decide on use of cemented arthroplasty taking into account age and mobility

Contrary to NICE guidance there remains a role for Austin-Moore hemiarthroplasty (AM) for patients with significant pre-existing comorbidities who are at higher risk of death and complications following cemented hemiarthroplasty. We analysed prospectively-collected data comparing uncemented AM hemiarthroplasty in frail, poorly-mobile patients, and cemented hemiarthroplasty. We analysed age, pre-operative morbidity, duration of operation, death rate and complication rate. AM patients were significantly older with significantly higher ASA grades. It took significantly longer to optimise them before surgery. AM was significantly shorter to perform. There was no significant difference in complications requiring re-operation. Twice as many AM patients developed post-operative pneumonia despite absence of cement. Twice as many AM patients died after surgery and a significant proportion died within the first month despite no increased risk of repeat operation, shorter operating time and no risk of cement-disease. We infer that these patients would likely have fared badly had they undergone a longer, cemented procedure. A modern cemented prosthesis costs £691 more than AM. There exists a subset of patients within the neck of femur cohort who are significantly more unwell. Contrary to guidelines, we suggest that the cheaper, user-friendly Austin-Moore can be a reasonable prosthesis to use for this cohort

The use of polymethylmethacrylate (PMMA) in orthopaedic reconstructive surgery can increase the possibility of cardiovascular dysfunction remains a debate. This study was undertaken to determine if cemented hemiarthroplasty is safe in treatment of femoral neck fracture in patients with ischemic heart disease. Between March 1999 and February 2004, we performed cemented hemiarthroplasties for displaced femoral neck fractures on 158 consecutive patients. This retrospective study consisted of 44 patients with ischemic heart disease(group 1) and 58 patients of age matched control(group 2). We compared the mortality rate, the incidence of deep vein thrombosis (DVT), pulmonary embolism, cerebrovascular disease, dislocation, deep infection, the amount of postoperative blood loss, and the grade of cementation by Barrack in radiograph between two groups. No difference was found in perioperative mortality rate, deep infection rate, the incidence of DVT or pulmonary embolism, the newly developed heart ischemic event or brain hemorrhagic lesion between the two groups. But there were more incidence of dislocation related to weakness by past brain ischemic lesion and the newly developed brain ischemia in patients of group 1 than group 2(p < 0.05). More importantly, six patients in group 1 had transient symptoms of dyspnea, signs of hypotension, and bradycardia during two days postoperatively, which is suspicious of embolic phenomenon, even though it was not confirmed. More closer and careful observations for the occurrence of dislocation related to previous brain ischemia, or newly developed brain ischemic lesion or embolic phenomenon and appropriate thromboprophylaxis are necessary in patients with ischemic heart disease after a cemented hemiarthroplasty for the treatment of femoral neck fracture

NICE guidelines support the use of total hip replacement (THR) in preference to cemented hemiarthroplasty for the treatment of fit and active elderly patients with a displaced intracapsular neck of femur fracture. We hypothesized that not all patients eligible for a THR received one in our unit. We performed a prospective cohort study including all consecutive hip fracture patients admitted to our unit over a 6 month period. Case notes and data from the National Hip Fracture Database were evaluated. Patients were deemed suitable for a THR if they mobilised outdoors with a maximum of one stick, had an abbreviated mental test score of 8 or greater and had an ASA score of 1 or 2. 256 patients sustained a neck of femur fracture during the study period and 36 met the inclusion criteria. 26 (72%) had cemented hemiarthroplasties and 10 (22%) had a THR. THR rates varied with the day of surgery. At our unit we have a low rate of THR for patients who fulfil the NICE criteria for suitability, however it is around the national average. This could be improved upon by increasing the availability of surgeons who are able to perform THR, especially on weekends

This study aims to investigate that a single dose of tranexamic acid (TXA) will reduce blood loss and transfusion rates in elderly patients, undergoing intertrochanteric (IT) or femoral neck fractures surgery. Consecutive elderly patients receiving hip fracture surgery for stable or unstable IT fracture, treated with short intramedullary nail (IMN) insertion as well as cemented hemiarthroplasty for acute femoral neck (subcapital) hip fracture, were screened for inclusion in this single-centre randomized trial. Patients were randomly allocated to a study group by sealed envelope. One TXA dose of 15 mg/kg i.v. diluted in 100 ml N/S or one placebo dose i.v. in 100 ml N/S were administered 5 mins before the skin cut. Haemoglobin (Hb) concentration was measured at admission time and prior to surgery. Post-operatively it was measured on a daily basis until day 4, giving a total of four Hb measurements (days 1 to 4). The transfusion trigger point was determined in accordance with the French guidelines for erythrocyte blood transfusion. The transfusion trigger was 10 g/dl for patients at risk, while in all other cases, it was 9 g/dl. Information regarding the transfusions number was assessed directly by the hospital blood bank database. Blood loss was calculated by the Hb dilution method. Nadler's formula was used to calculate patients' blood volume. For calculation of total blood loss (TBL) expressed to total Hb loss and total Volume loss, the number of transfusions (55 grams of Hb per transfusion), the Hb concentration on preoperatively (Hgbi) and the Hb concentration on the last measure (Hgbe) were used. (Hb balance method). The primary efficacy outcome was the number of transfusions of allogeneic RBC from surgery up to day 4. The secondary ones were the total blood loss from surgery to day 4 as it was calculated by Hb-balance method. After randomization, 35 patients with femoral neck fracture and 30 patients with IT fracture received TXA prior to surgery. Respectively, 30 patients with femoral neck fracture and 55 with IT fracture didn't receive TXA. The groups did not differ significantly in their basic demographics (age, gender, BMI, injury mechanism, ASA score, co-morbidities). Results showed that patients undergoing hemiarthroplasty after receiving TXA, were transfused with less allogeneic RBC and had less total blood loss than patients that didn't receive TXA, but without statistical significance. While patients treated with IMN in the TXA group received a significantly lower number of RBC units than the control group (1.28 ± 1.049 vs 2.075 ± 1.685), (P = 0.0396), had a significantly lower loss of Hb (98.59 ± 55.24 vs 161.6 ± 141.7), (P = 0.0195) and a lower total blood volume loss (951.3 ± 598.9 ml vs 1513 ± 1247 ml), (P = 0.023). This trial confirmed TXA administration efficacy in reducing blood loss and transfusion rate in elderly patients undergoing hip fracture surgery. A TXA single dose may be a safer option, taking into account these patients' physiological status and co-morbidities

Aims. This study aimed to compare the change in health-related quality of life of patients receiving a traditional cemented monoblock Thompson hemiarthroplasty compared with a modern cemented modular polished-taper stemmed hemiarthroplasty for displaced intracapsular hip fractures. Patients and Methods. This was a pragmatic, multicentre, multisurgeon, two-arm, parallel group, randomized standard-of-care controlled trial. It was embedded within the WHiTE Comprehensive Cohort Study. The sample size was 964 patients. The setting was five National Health Service Trauma Hospitals in England. A total of 964 patients over 60 years of age who required hemiarthroplasty of the hip between February 2015 and March 2016 were included. A standardized measure of health outcome, the EuroQol (EQ-5D-5L) questionnaire, was carried out on admission and at four months following the operation. Results. Of the 964 patients enrolled, 482 died or were lost to follow-up (50%). No significant differences were noted in EQ-5D between groups, with a mean difference at four months of 0.037 in favour of the Exeter/Unitrax implant (95% confidence interval (CI) 0.014 to 0.087, p = 0.156), rising to 0.045 (95% CI 0.007 to 0.098, p = 0.09) when patients who died were excluded. The minimum clinically important difference for EQ-5D-5L used in this study is 0.08, therefore any benefit between implants is unlikely to be noticeable to the patient. There was no difference in mortality or mobility score. Conclusion. Allowing for the high rate of loss to follow-up, the use of the traditional Thompson hemiarthroplasty in the treatment of the displaced intracapsular hip fracture shows no difference in health outcome when compared with a modern cemented hemiarthroplasty.

Purpose. To observe the follow-up results of standard cemented bipolar hemiarthroplasty with double loop and tension band wiring technique for treatment of unstable intertrochanteric hip fractures in elderly patients with osteoporosis. Materials and Methods. From May 2000 to May 2006, 86 cemented bipolar hemiarthroplasties were performed in elderly patients who had unstable intertrochanteric fractures. The mean age at the time of surgery was 82 years old. The average follow-up period were 5.3 years. We evaluated post-operative results after operation by clinical and radiographic methods. Results. Clinically, the final follow-up of Harrsi hip score was noted 79.2. The mean time needed for full weight bearing following surgery was 4.2 weeks and 82.5% of patients regained their preoperative ambulatory level. All patients achieved union in lesser trochanter fracuture, but great trochanter displacement were observed in 4 cases. There was one case of acetabular erosion. Post-operative superficial infections were found in 2 cases. 1 case with stem subsidence(<5 mm) showed satisfactory results without further subsidence in follow-ups. Conclusion. If we properly apply indications in technique with cemented bipolar hemiarthroplasty in the treatment of unstable intertrochanteric hip fracture in elderly, we will achieve systematic postoperative rehabilitation, pain control and handy nursing which is its one of merits

Cerebral micro emboli have been noted to occur during both total hip and knee arthroplasty. These micro emboli have been implicated in the causation of postoperative cognitive impairment. The aim of this study was to determine whether cerebral micro emboli occur during hip fracture surgery. 28 patients undergoing hip fracture surgery had transcranial doppler assessment of the middle cerebral artery to detect cerebral micro emboli. Micro embolic signals (MESs) were recorded during the operative procedure. Successful monitoring was carried out in 26 patients. MES were recorded in 16 out of 26 patients. 12 out of 16 patients who had MESs had undergone a cemented hemiarthroplasty; the remainder had a sliding hip screw for an extracapsular hip fracture. 75% (9/12) of patients who had a cemented hemiarthroplasty had the majority of MESs after reaming and cementing. MESs in the patients who had a sliding hip screw occurred throughout the operative procedure. Conclusion: Cerebral micro emboli do occur during hip fracture surgery. These emboli may be responsible for the cognitive dysfunction that occurs in this susceptible group of patients

Introduction. More than 60% of patients presenting with a hip fracture have significant medical co-morbidities and a one year mortality rate between 14% and 47%. The rating scale for the American Society of Anaesthetists (ASA) is a reliable predictor of both surgical risk and mortality with ASA 4 patients having 100% mortality at one year.1,2. Aims. Our aim was to establish a mortality rate for fractured neck of femur patients at three months and twelve months, and to ascertain the mortality of patients with an ASA 4 grading. Ultimately, should we be operating on this high risk cohort of patients'. We also chose to analyse our current practice in the management of displaced intracapsular neck of femur fractures in patients 90 years of age and over. Methods. Over 300 patients with a fractured neck of femur were identified between the 1st January 2007 and the 1st January 2008. A retrospective case note review of 151 patients was performed in conjunction with the NHS mortality database to establish whether each patient was alive or deceased. Our findings were compared to the standards set which included an overall mortality of 20% at three months, 30% at twelve months and 100% mortality for ASA 4 patients at twelve months. Results. Five patients were excluded from the study as one patient had incomplete data and four patients died prior to intended surgery. Only one of these patients had an ASA 4 grading. 146 patients were included and 23 patients (15.7%) were ASA 4. The overall mortality was 16% at three months and 23% at twelve months which was within the limits of the standards set. ASA 4 patients had a mortality of 57% at three months and 65% at twelve months which compared favourably with the limited literature available. There were 11 patients who were 90 years of age and over with intracapsular neck of femur fractures. Three of these patients were treated with a cemented hemiarthroplasty and were all alive at twelve months. Conclusions. Our study demonstrates a much better mortality rate in the ASA 4 patients than the limited literature available would suggest. We believe that ASA 4 patients should continue to be offered surgical intervention and that this data provides us with information to allow the patient and family to reach an informed decision with regard to their treatment. Intracapsular neck of femur fractures in patients 90 years of age and over can be treated with a cemented hemiarthroplasty provided they are deemed fit
