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

Aim. The aim of this investigation was to compare risk of infection in both cemented and cementless hemiarthroplasty (HA) as well as total hip arthroplasty (THA) following femoral neck fracture. Methods. Data collection was performed using the German Arthroplasty Registry (EPRD) In HA and THA following femoral neck fracture fixation method was divided into cemented and cementless protheses and paired according to age, sex, body mass index (BMI), and the Elixhauser score using Mahalanobis distance matching. Results. Overall in 13,612 cases of intracapsular femoral neck fracture, with 9,110 (66.9 %) HAs and 4502 (33.1 %) THAs were analyzed. Infection rate in HA was significantly reduced in cases with use of antibiotic-loaded cement compared to cementless fixated prosthesis (p=0.013). In patients with THA no statistical difference between cemented and cementless prothesis was registered, however after one year 2.4 % of infections were detected in cementless and 2.1 % in cemented THA. In the subpopulation of HA after one year 1.9 % of infections were registered in cemented and 2.8 % in cementless HA. BMI (p=0.001) and Elixhauser-Comorbidity-Score (p<0.003) were identified as risk factors of PJI, while in THA also cemented prosthesis demonstrated within the first 30 days an increased risk (HR=2.728; p=0.010). Conclusion. The rate of infection after intracapsular femoral neck fracture was significantly reduced in patients treated by antibiotic-loaded cemented hemiarthroplasty. In particular for patients with multiple risk factors for the development of a PJI the usage of antibiotic-loaded bone cement seems to be a reasonable procedure for prevention of infection

Aim

To review the outcome of deep prosthetic infection in patients following hip hemiarthroplasty surgery.

Regional anaesthesia is integral to best practice analgesia for patients with neck of femur fractures (NOFFs). These patients are generally frail and are vulnerable to side effects of opioid analgesia. Femoral nerve block (FNB) or fascia-iliaca block (FIB) can reduce opioid requirement. Literature supports good efficacy for extra-capsular NOFFs however it is acknowledged to be suboptimal for intracapsular fractures. We present a novel technique, using point of care ultrasound guidance to perform hip ultrasound guided haematoma (HUSH) aspiration, and injection of local anaesthetic (block) for intracapsular NOFFs. This a case control series. A consecutive series of cognitively intact patients, with an isolated intra-capsular NOFF, received a HUSH block using 10mls of 0.75% Ropivicaine. Haematoma was aspirated and volume recorded. This was performed in addition to standard NOFF pathway analgesia that includes a FIB and multimodal analgesia including opioids. Visual Analogue Scale (VAS)pain scores at rest and on movement were recorded pre and post procedure as well as combined morphine equivalent units administered post HUSH block. The control arm was a retrospective group of similar patients who followed the routine care pathway including a FIB. VAS pain scores from observation charts and usage of morphine equivalent units were calculated. Ten patients consented to receive HUSH blocks and we included thirty-eight patients in our control series. The HUSH block group showed mean VAS pain score of 4.2/10 at rest and 8.6 on movement prior to block. In the time after the block, VAS pain scores reduced to 1.5 at rest (p=0.007) and 3.1 on movement (p=0.0001) with a mean total morphine equivalent use of 8.75mg. This is significantly different from the control group's mean VAS pain at rest score 6.9 (p=0.0001) and 24.1mg total morphine equivalent (p=0.07). HUSH Block in addition to fascia iliaca block appears to significantly better pain relief in intracapsular neck of femur fracture patients when compared to fascia iliaca block alone. We believe it is relatively easy to perform with readily available ultrasound scanners in emergency departments

Abstract. Background. Dislocation of a hip hemiarthroplasty is a devastating complication with a high mortality rate in elderly patients. Previous studies have suggested a higher dislocation rate in patients with neuromuscular conditions. In this study, we have reviewed our larger cohort of patients to identify whether there is any association between neuromuscular disorders and prosthetic dislocation in patients treated with hip hemiarthroplasty for femoral neck fractures. Patients and Methods. Our study is a retrospective analysis of data collected over 34 years for patients with intracapsular neck of femur fracture who underwent hip hemiarthroplasty. The study population is composed of four groups: patients with no neuromuscular disorders, patients with Parkinson's disease, patients with previous stroke, and patients with dementia. Results. A total of 3827 patients were treated with hip hemiarthroplasty. For the 3371 patients with no neuromuscular condition (Group I) the dislocation rate was 1.1%. 219 patients had Parkinsonism (Group II) with a dislocation rate of 3.2%, 104 patients had a previous stroke with weakness on the fracture side with a dislocation rate of 1.0% (Group III), and 984 patients had severe dementia with a dislocation rate of 1.8% (Group IV). The increased dislocation rate for those with Parkinson's disease was statistically significant (p=0.02) while none of the other neuromuscular conditions were statistically significant. Conclusion. Our study demonstrates an increased risk of dislocation after hemiarthroplasty for patients with Parkinson's disease in comparison to other groups. No increase was apparent for those with dementia or weakness from a previous stroke

Current evidence suggests that we should be moving away from Thompson's hemiarthroplasties for patients with intracapsular hip fractures. Furthermore, the use of cement when inserting these prostheses is controversial. This study aims to show the Inverness experience. We performed a retrospective review of all NHS Highland patients who underwent a hemiarthroplasty for an intracapsular neck of femur fracture over the last 15 years. Demographics and the use of cement were documented. Further analysis of this group was performed to identify any of these patients who required revision of their prosthesis. Patients requiring revision had their case-notes reviewed to identify the cause for further surgery. From 1996 until present 2221 patients from the Highland area had a hemiarthroplasty for an intracapsular neck of femur fracture. 1708 where female (77%) and 513 male (23%). The ages ranged from 28 years to 104 years (mean 80 years, median 81). 2180 of this group had their operations in Raigmore Hospital with the remaining 41 at various centres throughout Scotland. 623 (28%)had a cemented hemiarthroplasty, with the remaining 1578 (72%) having an uncemented Thompson's hemiarthroplasty. The revision rate for the cemented group was 2% (13 of 623 patients). In the uncemented group it was 0.4% (6 of 1578). Reasons from revision included dislocation, periprosthetic fracture, infection and pain. Current evidence from some joint registers regarding the use of Thompson's hemiarthroplasty in the elderly is discouraging. The use of bone cement in this group with multiple co-morbidities is not without it's risks. Our data suggests that uncemented Thompson's hemiarthroplasties in low demand elderly patients with multiple co-morbidities can yield excellent results with less risk to the patients

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

Recent NICE guidelines have suggested abandoning the Thompson hemiarthroplasty (TH) in favour of a ‘proven prosthesis’ such as the Exeter Trauma Stem (ETS). This is controversial because of significant cost implications and limited research assessing outcomes of the ETS. The aim of this study was to assess the treatment of intracapsular neck of femur fractures with the TH. Between 2002 and 2006 (minimum 5 year follow-up), 431 cemented TH's were performed. Death rate at 1 year and 5 years were 26.0% and 67.7% respectively. Dislocation (1.4%) and infection (0.2%) rates were low and revision rate was 1.2%. Comparison was made to Bipolar hemiarthroplasties over the same period (total 194). These had lower rates of dislocation (0.5%) and infection (0.5%) with a significantly higher (3.6%) revision rate. We feel that the TH remains the current gold standard treatment for intracapsular fractures, in appropriate patients, due to low complication and revision rates. Modern implants may provide better function or longevity, but there is no evidence in the literature to support abandoning the TH. Surgeons should assess patients and decide on its use, despite NICE guidelines, as it remains a cost effective treatment method, particularly for older, less mobile and cognitively impaired patients

Long-term prospective RCT comparing hemiarthroplasty (HEMI) and total hip arthroplasty (THA) for the treatment of intracapsular neck of femur fracture. 81 previously mobile, independent, orientated patients were randomised to receive THA or HEMI after sustaining a displaced neck of femur fracture. Patients were followed up with radiographs, Oxford hip score (OHS), SF-36 scores and their walking distance. At a mean follow up of 8.7 years, overall mortality following THA was 32.5% compared to 51.2% following HEMI (p=0.09). Following THA, patients died after a mean of 63.6 months compared to 45 months following HEMI (p=0.093). Patients with THA walked further and had better physical function. No HEMIs dislocated but three (7.5%) THAs did. Four (9.8%) HEMI patients were revised to THA, but only one (2.5%) THA required revision. All surviving HEMI patients had acetabular erosion and all surviving THA patients had wear of the cemented polyethylene cup. Patients with THA have better function in the medium-term and survive longer

Most studies about hemi-arthroplasty of hip have focused on clinical aspects. Design features of various implants of hemi-arthroplasty have not been studied extensively. The aim was to investigate the relationships between radiological variables and possible mode of failure in various hemiarthroplasty implants in intracapsular neck of femur fractures. A retrospective review of 42 hemi hip arthroplasties, Austin Moore and Thompson prosthesis by Biomet, Medical Product Service (Tipsan) and Smit Medimed (SMPL) used in our hospital. Controversy exists between indication for a particular design in an unselected series of patients once excluding the choice of cementing or uncementing the prosthesis. In monoblock prosthesis not only the head-neck region affects the stability but also the stem fit in proximal femur. Surgeon preference to technique and approach excluded. Premorbidly all patients were mobilising independently. 5 criteria reviewed. 1) head size of prosthesis 2) neck length 3) prosthesis stem shaft angle 4) stem-cortical distance ratio and 5) shape of the femoral canal as classified by Dorr. Head size compared in AP views of involved hip and normal head size compared with that of prosthesis. A difference <2 mm or >3 mm indicative of incorrect size. Neck length measured by the vertical distance from center of head to superior aspect greater trochanter was zero. A range of +/− 5 mm was acceptable. Neck shaft angle with a difference of >5 degrees was indicative of varus position of the stem. Canals of the proximal femoral categorized as a) stove pipe b) champagne c) fluted varieties radiologically. X-ray magnification corrected. All measurements were done on immediate postoperative radiographs. Stability of various design features of straight stemmed and curved implants are dependant on the anterior bowing angle and canal ratio of femur to prosthesis. A prospective study with CT from selected shapes of the proximal femoral is being carried out. Inappropriate head size as reported by Thompson or neck length was related to incidence of dislocation resulting in failure. Our findings emphasise importance of careful selection of a particular implant design towards the morphology of the femoral canal

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.
