Recent NICE guidelines suggest that Total Hip Arthroplasty (THA) be offered to all patients with a displaced intracapsular neck of femur fracture who: are able to walk independently; not cognitively impaired and are medically fit for the anaesthesia and procedure. This is likely to have significant logistical implications for individual departments. Data from the National Hip Fracture Database was analysed retrospectively between January 2009 and November 2011. The aim was to determine if patients with displaced intracapsular neck of femur fractures admitted to a single tertiary referral orthopaedic trauma unit received a THA if they met NICE criteria. Case notes were then reviewed to obtain outcome and complication rates after surgery. Five hundred and forty-six patients were admitted with a displaced intracapsular neck of femur fracture over the described time period. Sixty-five patients met the NICE criteria to receive a THA (mean age 74 years, M:F = 16: 49); however, 21 patients had a THA. The other patients received either a cemented Thompson or bipolar hemiarthroplasty. Within the THA cohort there were no episodes of dislocation, venous thromboembolism, significant wound complications or infections that required further surgery. Within the hemiarthroplasty cohort there was 2 mortalities, 2 implant related infections, 1 dislocation and 2 required revision to a THA. There is evidence to suggest better outcomes in this cohort of patients, in terms pain and function. There is also a forecasted cost saving for departments, largely due to the relative reduction in complications. However, there were many cases (44) in our department, which would have been eligible for a THA, according to the NICE guidelines, who received a hemiarthroplasty. This is likely a reflection of the increased technical demand, and larger logistical difficulties faced by the department. We did note more complications within the hemiarthroplasty group, however, the numbers are too small to address statistical significance, and a longer follow up would be needed to further evaluate this. There is a clear scope for optimisation and improvement of infrastructure to develop time and resources to cope with the increased demand for THA for displaced intracapsular neck of femur fractures, in order to closely adhere to the NICE guidelines

The two commonest types of hemiarthroplasty used for the treatment of a displaced intracapsular fracture are the uncemented Austin Moore Prosthesis and cemented Thompson hemiarthroplasty. To determine if any difference in outcome exists between these implants we undertook a prospective randomised controlled trial of 300 patients with a displaced intracapsular hip fractures. All operations were performed or supervised by one orthopaedic surgeon and all by a standard anterolateral approach. Patients were followed by a nurse blinded in the type of prosthesis to assess residual pain and mobility. The average age of the patients was 83 years and 23% were male. 73% came from their own home with the remainder from institutional care. There was no statistically significant difference in mortality between groups, with 34/151 having died at one year in the cemented group and 45/149 in the uncemented group. Pain scores (grade 1-6) were less for those treated by a cemented prosthesis (mean score 1.8 versus 2.4, p value <0.00001). Mobility change was also less for those treated with a cemented implant (p=0002). No difference was found in hospital stay. Operative complications are as listed. One case of non-fatal intraoperative cardiac arrest occurred in the cemented group. In summary a cemented Thompson Hemiarthroplasty causes less pain and less deterioration in mobility compared to uncemented Austin Moore hemiarthroplasty, without any increase in complications. The continued use of an uncemented Austin Moore cannot be recommended

Hip fractures are a leading cause of hospital admission and an increasing problem within the ageing population. The two main treatment options for displaced intracapsular fractures are total hip arthroplasty and hemiarthroplasty. This service evaluation aims to compare the outcomes of patients over 80 years old with a younger cohort undergoing the two main treatment modalities. The study included 378 patients admitted to a major UK trauma centre between April 2011 and March 2013. The main outcome measures were: mortality rate at 30 days and 1 year; reoperation rate at 30 days; proportion living in their own home/sheltered accommodation at 30 days, 1 year and upon NHS discharge; change in walking ability indoors and outdoors at 30 days and 1 year. All patients receiving THA were discharged home compared to 74.3% under 80 receiving hemiarthroplasty and 57.3% over 80 receiving hemiarthroplasty. No THA patients required reoperation at 30 days. 4.4% under 80 receiving hemiarthroplasty required reoperation, as did 2.0% over 80 receiving hemiarthroplasty. Mortality rates were higher following hemiarthroplasty. Patients receiving THA in both age groups were more likely to retain their pre-injury walking ability at 1 year; however loss of walking ability was similar at 30 days regardless of age or treatment. Patients receiving THA in the trust had less risk of mortality and reoperation with an increased chance of retaining pre-injury walking ability and place of residence; however these patients were healthier prior to the operation. Age had a larger impact on walking ability for those receiving hemiarthroplasty

Introduction. National Institute for Health and Clinical Excellence (NICE) guidelines recommend the use of total hip replacement (THR) for displaced intracapsular fractured neck of femur (NOF) in cognitively intact patients who were independently mobile prior to the injury. The National Joint Registry for England and Wales (NJR) has collected data on THRs performed since 2003. This retrospective cohort study explores risk factors independently associated with implant failure and perioperative mortality. Methods. NJR data recording a THR performed for acute fractured NOF between 2003 and 2010 were analysed. Cox proportional hazards models were used to analyse the extent to which risk of implant revision was related to specific covariates. Multivariable logistic regression was used to analyse factors affecting 90-day perioperative mortality. Significance was taken as p< 0.01. Result. A total of 4495 procedures were analysed, of which 83 (1.9%) underwent revision surgery and 144 (3.2%) patients died within 90 days. Increased risk of implant revision was associated with the use of cementless prostheses (Hazard Ratio [HR]=2.23, p=0.001), but revision risk was independent of age, American Society of Anaesthesiologists (ASA) grade, gender, head size and head material. Risk of mortality within 90 days was significantly associated with high ASA (grade 3: Odds ratio [OR]=7.20, p< 0.001, grade 4/5: OR=38.09, p< 0.001, referenced to grade 1 group) and older age (≥81 years: OR=2.04, p=0.004, referenced to 60–70 years group). Mortality risk was lower in patients who had a hybrid THR (OR=0.51 p=0.004), after risk adjustment. Conclusion. There is considerably greater risk of implant revision when cementless THR is used for managing fractured NOF. Risk of perioperative mortality is greatest in patients over 80 years with ASA grades 3 or above, and lowest with hybrid THR. This information may be used to guide the surgical management of patients with fractured neck of femur

The ideal operative treatment of displaced sub capital femoral fractures in the elderly is controversial. Recently, randomised controlled trials have suggested a better outcome with the use of total hip arthroplasty (THA) to treat displaced intra capsular fractures of the femur for elderly patients in good health. More recently the concept of dual mobility cups is being promoted to avoid dislocations in this cohort of patients. However, overall there is limited evidence to support the choice between different types of arthroplasty. Dislocation remains a main concern with THA, especially when a posterior approach is used. We analysed the outcome of 115 primary THR (112 cements and 3 uncemented) THR using a posterior approach with soft tissue repair in active elderly patients presenting with displaced intra capsular femoral neck fractures. Size 28 mm head was used in 108 and a size 32 mm head in the rest. All surgery was performed by specialist hip surgeons. Satisfactory results were noted in terms of pain control, return to pre-morbid activity and radiological evidence of bone implant osteo-integration. The 30-day mortality was nil. There were two dislocations and only one needed revision surgery due to recurrent dislocation. In conclusion, with optimal patient selection, THA seems to provide a good functional outcome and pain relief in the management of displaced intracapsular femoral neck fractures. Excellent outcome can be achieved when done well using the standard cemented THR and with 28mm head. A good soft tissue repair and a specialist hip surgeon is preferable

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

Introduction. Cemented hemiarthroplasty for neck of femur fractures has been advocated over uncemented hemiarthroplasty due to better post-operative recovery and patient satisfaction. However, studies have shown adverse effects of bone cement on the cardio-respiratory system which may lead to higher morbidity and mortality. Therefore, in some institutes, the use of an uncemented prosthesis has been adopted for patients with a high number of co-morbidities. The aim was to compare early mortality rates for cemented vs. uncemented hemiarthroplasties. Method. Cohort study of displaced intracapsular hip fractures treated with hemiarthroplasty between 1999–2009 at one institute. A total of 3094 hemiarthroplasties performed; out of which 1002(32.4%) were cemented and 2092(67.6%) were uncemented. 48hour and 30day mortality rates for the two groups were compared and a multivariate Cox regression model used to eliminate confounding factors. Significant confounding factor included age, sex, mini mental test score, medical co-morbidities, Nottingham Hip Fracture Score and delay to surgery. Results. The study showed that, after eliminating confounding factors, 48hour mortality in the cemented group was 0.3% compared to 0.5% in the uncemented group (p=0.388). However, the adjusted 30day mortality rate for the cemented group (4%) was shown to be significantly lower than for the uncemented group (10.8%) (p< 0.001). Conclusion. The use of cement in hip hemiarthroplasty is not associated with an increased rate of mortality at 48hours or at 30days. Along with emerging evidence of better post-op recovery and patient satisfaction with the use of a cemented prosthesis, we support the use of cement for all patients undergoing hip hemiarthroplasty

Background. There is increasing interest in the use of Total Hip Replacement (THR) for reconstruction in patients who have suffered displaced intracapsular hip fractures. Patient selection is important for good outcomes but criteria have only recently been clearly defined in the form of national guidelines. This study aims to investigate patient reported outcomes and satisfaction after Total Hip Replacement (THR) undertaken for displaced hip fractures and to compare these with a matched cohort of patients undergoing contemporaneous THR for osteoarthritis in order to assess the safety and effectiveness of national clinical guidelines. Methods. 100 patients were selected for treatment of displaced hip fractures using THR between 1 January 2007 and 31 December 2009. These patients were selected using national guidelines and were matched for age and gender with 300 patients who underwent contemporaneous THR as an elective procedure for osteoarthritis. Results. Patients undergoing THR for both fracture and as an elective procedure reported excellent outcomes and satisfaction. Hip fracture patients had better post-operative Oxford hip scores (p< 0.001) and SF-12 physical component scores (p< 0.001). Mental component scores were poorer for hip fracture patients (p< 0.001). In this series, the rates of major complications for hip fracture patients were higher than for elective patients. Nevertheless, the rates of dislocation, deep infection and early revision surgery were similar to those widely reported in the literature and considered within acceptable limits after elective surgery. Conclusions. For selected patients, THR undertaken for displaced fractures of the hip produces outcomes which are at least equivalent to those achieved after elective surgery. Selection is critical to this success and the extended use of current guidelines is appropriate and safe

Aims

This study aimed to identify patients receiving total hip arthroplasty (THA) for trauma during the peak of the COVID-19 pandemic in the UK and quantify the risks of contracting SARS-CoV-2 virus, the proportion of patients requiring treatment in an intensive care unit (ICU), and rate of complications including mortality.

The clinical results of the cemented Exeter stem in primary hip surgery have been excellent. The Exeter ‘philosophy’ has also been extended into the treatment of displaced intracapsular hip fractures with ‘cemented bipolars’ and the Exeter Trauma Stem (Howmedica). We have identified an increase in the number of periprosthetic fractures that we see around the Exeter stem. We have also identified a particular group of patients with comminuted fractures around ‘well fixed’ Exeter stems after primary hip surgery that present a particular difficult clinical problem. Prior to fracture, the stems are not loose, the cement mantle remains sound and bone quality surrounding the reconstruction is good, i.e. classifying it as a Vancouver B1. However the comminuted nature of the fracture makes reduction and fixation with traditional methods difficult. Therefore in these particular circumstances it is often better to manage these as B2 or even B3 fractures, with distal bypass and uncemented reconstruction. Over an eleven-year period since 1999, 185 patients have been admitted to Nottingham University Hospitals with a periprosthetic femoral fracture around a hip replacement. These patients were identified from a prospective database of all trauma patients admitted to the institution. Of these patients we have identified a cohort of 21 patients (11%) with a periprosthetic fracture around an Exeter polished stem. Hospital notes were independently reviewed and data retrieved. Outcome data was collected with end points of fracture union, re-revision surgery and death. Data was also collected on immediate and long term post-operative complications. The mean age was 76 years at time of fracture, and 52% were male. The mean duration between primary index surgery and fracture was 18 months (median 11 months). 15 patients were classified as Vancouver B1, and six as B2 fractures. Of the B1 fractures, 14 underwent fixation and one was treated non-operatively. Of the B2 fractures, four were revised, one was revised and fixed using a plate, and one was fixed using a double-plating technique. Prior to fracture, none of the implants were deemed loose although one patient was under review of a stress fracture which subsequently displaced. One patient died prior to fracture union. All the other patients subsequently went onto unite at a mean of 4 months. There were no deep infections, non- or malunions. No patient underwent further surgery. Dislocation occurred in one patient and a superficial wound infection occurred in one patient which responded to antibiotic treatment. Three other patients have subsequently died at seven, twelve and fifty-three months post fracture due to unrelated causes. In our series of patients, in addition to the more standard fracture patterns, we have identified a very much more comminuted fracture. Indeed, we have described the appearance as if the tapered stem behaves like an axe, splitting the proximal femur as a consequence of a direct axial load. As a consequence of the injury, the cement mantle itself is severely disrupted. There is significant comminution and soft tissue stripping, calling into question the viability of the residual fragments. Treatment of this type of fracture using a combination of plates, screws and cables is unlikely to provide a sufficiently sound reconstruction. In our experience we believe these fractures around previously ‘well fixed’ Exeter stems should be treated as B2/B3 injuries
