Aims. The aim of this investigation was to compare risk of infection in both cemented and uncemented hemiarthroplasty (HA) as well as in 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 uncemented prostheses and paired according to age, sex, BMI, and the Elixhauser Comorbidity Index using Mahalanobis distance matching. Results. Overall in 13,612 cases of intracapsular femoral neck fracture, 9,110 (66.9%) HAs and 4,502 (33.1%) THAs were analyzed. Infection rate in HA was significantly reduced in cases with use of antibiotic-loaded cement compared with uncemented fixated prosthesis (p = 0.013). In patients with THA no statistical difference between cemented and uncemented prosthesis was registered, however after one year 2.4% of infections were detected in uncemented 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 uncemented HA. BMI (p = 0.001) and Elixhauser Comorbidity Index (p < 0.003) were identified as risk factors of periprosthetic joint infection (PJI), while in THA cemented prosthesis also demonstrated an increased risk within the first 30 days (hazard ratio (HR) = 2.73; p = 0.010). Conclusion. The rate of infection after intracapsular femoral neck fracture was statistically significantly reduced in patients treated by antibiotic-loaded cemented HA. Particularly 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.

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

Arthroplasty is the most effective management of displaced intracapsular femoral neck fracture. Hemiarthroplasty (HEMI) is associated with acetabular erosion and loosening in mobile patients and total hip arthroplasty (THA) with instability. We sought to establish whether HEMI or THA gave better results in independent mobile patients with displaced intracapsular femoral neck fracture. Eighty-two patients were randomised into two groups. One arm received a modular HEMI, the second a THA using the same femoral stem. Patients were followed for a mean of three years after surgery. After HEMI, eight patients died, two were revised to THA and there is intention to revise three. One patient had a periprosthetic fracture. Mean walking distance was 1.08 miles and Oxford Hip Score (OHS) 22.5. Twenty patients (64.5% of survivors) had radiological evidence of acetabular erosion. After THA, four patients died, three dislocated, one required revision. Mean walking distance was 2.23 miles and OHS was 18.8. HEMI is associated with a higher rate of revision than THA and potential revision because of acetabular erosion. THA after three years displayed superior walking distances (p=0.039) and lower OHS (p=0.033). THA is a preferable option to HEMI in independent mobile elderly patients with displaced intracapsular femoral neck fracture

Abstract. Objectives. The use of cannulated screws for femoral neck fractures is often limited by concerns of avascular necrosis (AVN) occurring, historically seen in 10–20% of fixed intracapsular fractures. The aim of this study was to investigate the rate of AVN with current surgical techniques within our unit. Methods. A single centre retrospective review was performed. Operative records between 1st July 2014 and 31st May 2019 were manually searched for patients with an intracapsular neck of femur fracture fixed with cannulated screws, with minimum one year follow up. Patient records and radiographs were reviewed for clinical and radiographic diagnoses of AVN and/or non-union. Fracture pattern and displacement, screw configuration and reduction techniques were recorded, with radiographs independently analysed by five orthopaedic surgeons. Results. Sixty-five patients were identified, average age of 72 years (range 48–87). Thirty-six patients (55%) sustained displaced fractures and 29 patients (45%) had undisplaced fractures. Two (3%) patients developed AVN, with no cases of fracture non-union. Ten patients (15%) sustained a high-energy injury, though none of these patients developed AVN. Screws configurations were: two (3%) triangle apex-superior, 39 (60%) triangle apex-inferior, 22 (34%) rhomboid and two (3%) other, with nine (14%) cases using washers. All fractures required closed reduction; no open reductions performed. Conclusions. Our observed AVN rate is much lower than widely reported, especially given the proportion of displaced fractures that were fixed. With adequate fixation, even in displaced fracture patterns with imperfect reduction, cannulated screws are an excellent option for intracapsular neck of femur fractures. Declaration of Interest.

Aims: To calculate one-year survival after dislocated intracapsular femoral neck fractures and to assess factors associated with increased risk of death. Patients: 2045 patients treated for dislocated intracapsular femoral neck fractures during 2005 were registered in The Norwegian Hip Fracture Registry and were included in the present study. Methods: Almost all hospitals in Norway reported proximal femoral fractures to the Registry using standard forms filled in by the operating surgeons. Survival was calculated using Kaplan Meier survival analyses, and the impact of factors possibly influencing the survival was estimated using Cox regression analysis. Mortality data for all patients were obtained from Statistics Norway. Results: 2045 patients having dislocated intracapsular femoral neck fractures operated with 2 pins/screws (1071) and bipolar hemiprosthesis (974) were enrolled in the Registry during 2005. Among these, 333 patients died within the first year after the operation; 2 pins/screws (170) and bipolar hemiprosthesis (163). Factors adversely associated with survival included high age, male gender, dementia and with an increase in preoperative ASA classification. No statistically significant difference was found regarding preoperativ delay or for the two different treatment methods. Conclusion: After one year there is no difference in risk of death between operation methods; 2 pins/screws and hemiprosthesis, for dislocated femoral neck fractures

Introduction: Arthroplasty is the most effective management of displaced intracapsular femoral neck fracture. Hemiarthroplasty (HEMI) is associated with acetabular erosion and loosening in mobile active patients and total hip arthroplasty (THA) with instability. We sought to establish whether HEMI or THA gave better results in independent mobile patients with displaced femoral neck fracture. Method: Eighty-one patients were randomised into two groups. One arm received a modular HEMI, the second a THA using the same femoral stem. Patients were followed for a mean of three years after surgery. Results: After HEMI, eight patients died, two were revised to THA and there is intention to revise three. One patient had a Peri-prosthetic fracture. Mean walking distance was 1.08 miles and Oxford Hip Score (OHS) 22.5. Twenty patients (64.5% of survivors) had radiological evidence of acetabular erosion. After THA, three patients died, three dislocated, one required revision. Mean walking distance was 2.23 miles and OHS was 18.8. There was no radiological evidence of polyethylene wear. Patients with THAs after three years walked further (p=0.039) and had a lower OHS (p=0.033). Discussion: HEMI is associated with a higher actual and potential revision rate than THA because of acetabular erosion, higher OHS after three years and shorter walking distances. THA is a preferable option to HEMI in independent mobile elderly patients with displaced intracapsular femoral neck fracture

Intracapsular neck of femur fractures may be treated with fixation or arthroplasty, depending on fracture characteristics and patient factors. Two common methods of fixation are the sliding hip screw, with or without a de-rotation screw, and cannulated screws. Each has its merits, and to date there is controversy around which method is superior, with either method thought to risk avascular necrosis of the femoral head (AVN) rates in the region of 10–20%. Fixation with cannulated screws may be performed in various ways, with current paucity of evidence to show an optimum technique. There are a multitude of factors which are likely to affect patient outcomes: technique, screw configuration, fracture characteristics and patient factors. We present a retrospective case series analysis of 65 patients who underwent cannulated screw fixation of a hip fracture. Electronic operative records were searched from July 2014 until July 2019 for all patients with a neck of femur fracture fixed with cannulated screws: 68 were found. Three patients were excluded on the basis of them having a pathological fracture secondary to malignancy, cases were followed up for 2 years post-operatively. Electronic patient records and X-rays were reviewed for all included patients. All X-rays were examined by each team member twice, with a time interval of two weeks to improve inter-observer reliability. 65 patients were included with 2:1 female to male ratio and average age of 72 years. 36 patients sustained displaced fractures and 29 undisplaced. Ten patients sustained a high-energy injury, none of which developed AVN. Average time to surgery was 40 hours and 57 patients mobilised on day one post-operatively. All cases used either 7 or 7.3mm partially threaded screws in the following configurations: 2 in triangle apex superior, 39 triangle apex inferior, 22 rhomboid and 2 other, with 9 cases using washers. All reductions were performed closed. Five (8%) of our patients were lost to follow-up as they moved out of area, 48 (74%) had no surgical complications, seven (11%) had mild complications, three (5%) moderate and two (3%) developed AVN. Both of these sustained displaced fractures with low mechanism of injury, were female, ASA 2 and both ex-smokers. One received three screws in apex inferior configuration and one rhomboid, neither fixed with washers. Our AVN rate following intracapsular hip fracture fixation with cannulated screws is much lower than widely accepted. This study is under-powered to comment on factors which may contribute to the development of AVN. However, we can confidently say that our practice has led to low rates of AVN. This may be due to our method of fixation; we use three screws in an apex inferior triangle or four screws in a rhomboid, our consultant-led operations, closed reduction of all fractures, or our operative technique. We pass a short thread cannulated screw across the least comminuted aspect of the fracture first in order to achieve compression, followed by two or three more screws (depending on individual anatomy) to form a stable construct. Our series shows that fixation of intracapsular hip fractures with cannulated screws as we have outlined remains an excellent option. Patients retain their native hip, have a low rate of AVN, and avoid the risks of open reduction

Abstract

Aim

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

Abstract. Objectives. Hip instability following total hip arthroplasty in treatment of intracapsular neck of femur fractures is reported at 8–11%. Utilising the principle of a small articulation to minimize the problems of wear coupled with a large articulation, dual-mobility total hip arthroplasty prostheses stabilise the hip further than conventional fixed-bearing designs. The aim of this study is to compare the rate of dislocation and complication between standard fixed-bearing and dual-mobility prostheses for the treatment of intracapsular neck of femur fractures. Methods. A four-year retrospective review in a large district general hospital was completed. All cases of intracapsular neck of femur fractures treated with total hip arthroplasty were identified through the theatre logbooks. Patient's operative and clinical notes were retrospectively reviewed to collect data. Results. A total of 91 patients underwent total hip arthroplasty for intracapsular neck of femur fracture in the four-year period. 61.5% were dual-mobility design versus 28.5% had fixed-bearing implants. There were no statistical differences between patient group characteristics. Choice of implant was dependent on surgeon preference. There was a 0.0% dislocation rate in the dual-mobility group versus 8.6% in the fixed-bearing prosthesis group. All dislocations occurred in patients who underwent total hip arthroplasty with 36.0mm fixed-bearing prosthesis via posterior surgical approach. There was no statistical difference in mortality between both groups. Conclusion. There was an increasing trend of towards the use of dual-mobility prosthesis for fractured neck of femur within this department with excellent outcomes. Dual-mobility designs provide reduced dislocation rates in total hip arthroplasty in intracapsular neck of femur fractures compared to standard fixed-bearing designs at this institution. The authors recommend that all orthopaedic staff consider the use of dual-mobility prostheses in suitable patients and ensure trainees are suitably trained in use of dual-mobility designs.

Background. Intracapsular neck of femur fractures are one of the most common injuries seen in Orthopaedics. When the fracture is amenable to internal fixation there are 2 main treatment options, namely multiple cannulated hip screws (MCS) and 2-hole sliding hip screws (SHS). In this retrospective study we examine the outcomes associated with these two methods of internal fixation. At present there is little consensus regarding which treatment should be used. Methods. 161 patients were found to have suffered intracapsular neck of femur fracture treated with either SHS or MCS fixation over a 5 year period from April 2009 to April 2014, allowing at least 1 year follow up following injury. The patients imaging and clinical notes were then reviewed to ascertain the outcome of their treatment and any complications. Results. 93 patients were treated with a sliding hip screw compared to 68 that had been treated with cannulated screws. To ensure the fractures in each group were comparable in terms of fracture severity they were classified using gardens and pauwels score. The mean age of the group treated with SHS was 75.15 years, 7.69 years higher than those treated with MCS. The mean length of inpatient stay was 4.7 days longer for patients treated with sliding hip screws than those treated with cannulated screws, which is significantly more than would be predicted by age difference alone. Further patients were excluded for analysis of failure rate if they had not been sufficiently followed up, leaving 122 patients, 58 treated with MCS and 64 with SHS. A significantly higher (p=0.0136) proportion of patients treated with SHS (32%) suffered failure of their fixation compared to those treated with MCS (10%). The SHS group was further classified by whether or not a permanent derotation screw was employed. The use of a derotation screw provided protection against failure with a number needed to treat of 3.82, decreasing the failure rate to 14% which was not significantly more than the failure rate for MCS. Conclusions. We recommend that the first choice treatment for intracapsular neck of femur fractures amenable to internal fixation should be cannulated screws due to a lower rate of failure and shorter length of inpatient stay. If a surgeon has a strong preference for sliding hip screw we strongly recommend inserting a permanent derotation screw

Introduction: The best method of management of displaced intracapsular femoral neck fractures in elderly patients remains undecided. Most are treated by hemiarthroplasty. Aim: To clarify the issue of whether or not to use cement in hemiarthroplasty for displaced, intracapsular, femoral neck fractures in the elderly. Methods: Consecutive patients with displaced, intracapsular, femoral neck fractures treated by hemiarthroplasty between January 1997 and May 1998, in two hospitals within one region were reviewed. The same monoblock prosthesis was used; in Hospital A they were uncemented (121 patients), and in Hospital B they were cemented (123 patients). All surviving patients (50 and 56 respectively) were interviewed for assessments of pre-fracture and current pain, walking ability, use of walking aids and activities of daily living (ADL), using validated scoring systems. The average follow-up was 36 months. Results: The patients’ demographical data were similar (the mean age was 82 and 84 years respectively). There was no greater incidence of intra-operative fall in diastolic blood pressure or oxygen saturation in the cemented group. Cemented procedures took, on average, 15 minutes longer. Fewer of the cemented group had been revised or were awaiting revision (p=0.036). There was no difference in complication or mortality rates at any time between surgery and follow-up (p=0.86). Prospective assessment revealed highly significant differences in favour of cement, in terms of pain (p=0.003), walking ability (p=0.002), use of walking aids (p=0.004) and ADL (p=0.009). Conclusion: Our findings support the use of cemented hemiarthroplasty for the displaced intracapsular femoral neck fracture in the elderly patient

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

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

Introduction: Intracapsular femoral neck fractures in adults under 65 years old are associated with significant complications such as avascular necrosis of the femoral head and non-union. Timing of surgery remains controversial, with some studies suggesting that early surgical fixation reduces the rate of these complications. Presently the policy in this Fracture Unit remains early fixation (target less than twelve hours). The purpose of this study is to determine if this twelve hour target is being achieved and if not, where the delays are occurring. Methods: A retrospective case-note and data analysis was performed on all patients aged under 65 who underwent internal fixation of displaced intracapsular femoral neck fractures (Garden III/IV) between 31/12/06 and 31/12/07. The following data was collected; time of injury to presentation at health service, time from presentation at health service to admission at treating hospital, time of admission at treating hospital to time of surgery and overall time from injury to surgery. The main causes of delay were also determined. Results: In the one year period, there were 37 young adults with displaced intracapsular femoral neck fractures, with a mean age of 52.57 years. There were 23 females (62.2%) and 14 males (37.8%). We also present the reasons for delay at each stage including transfer delays, medical delays and limited emergency theatre availability. Discussion: Early operative fixation of young femoral neck fractures remains controversial. In this unit where it is advocated, the median time from injury to fixation is 22.18 hours. By reducing transfer times, increasing emergency theatre availability and improving efficiency of patient preparation for theatre at ward level, the twelve hour targets will be much more attainable

The Austin Moore Prosthesis (AMP) is a recognised treatment option in the management of displaced intracapsular femoral neck fractures in elderly patients. Peri-prosthetic femoral fractures are a potential complication of both cementless and cemented hemiarthroplasty and can occur intra-operatively or at any stage following implant insertion. Over a two-year period, 244 patients underwent hemiarthroplasty for a displaced intracapsular femoral neck fracture. Seventy patients had an AMP inserted whilst 174 patients were treated using a cemented Thompson stem. All of the AMP’s were inserted by, or under the supervision of an orthopaedic consultant. Five patients (7%) from the AMP group sustained a periprosthetic femoral fracture. Four required revision surgery. The remaining case was managed non-operatively. When compared to the cemented Thompson hemiarthroplasties performed over the same time period, despite the operating time being significantly less, the number of periprosthetic femoral fractures was significantly greater with the AMP. Furthermore, the early mortality rate was significantly higher for the AMP group who, were also significantly older and more likely to require postoperative blood transfusion. There was no significant difference in gender or ASA grade between the two groups. These findings suggest that for displaced intracapsular femoral neck fractures in elderly patients, when hemiarthroplasty is the treatment of choice, a cemented prosthesis is preferable

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

The best management of displaced intracapsular femoral neck fractures in the elderly remains undecided. Most are treated by hemiarthroplasty. The aim of this study was to establish whether the advantages of cement outweigh the disadvantages. All patients with displaced intracapsular femoral neck fractures treated with herniarthroplasty between January 1997 and May 1998, in 2 hospitals within the same Deanery, were reviewed. The same prosthesis was used, but in hospital A they were uncemented, and in B cemented. There were 122 patients in hospital A and 123 in B. We conducted a detailed retrospective analysis of hospital notes. All surviving patients (50 and 56 respectively) were interviewed to obtain pre-fracture and current scores of pain, walking ability, use of walking aids, activities of daily living (ADL) and accommodation status, using validated scoring systems. The relative deterioration over the follow-up period (32–36 months) was determined and the groups compared. Patient demographics confirmed comparability of groups. There was no greater incidence of intra-operative fall in diastolic blood pressure, or oxygen saturation in the cemented group. Cemented procedures were on average 15 minutes longer. Median in-patient stay was the same. Significantly fewer of the cemented group had been revised or were awaiting revision (p=0. 036). There was no difference in mortality rates at any point between surgery and follow-up. Prospective assessment of surviving patients revealed highly statistically significant greater deterioration in pain (p=0. 003), walking ability (p=0. 002), use of walking aids (p=0. 003) and ADL (p=0. 009) in the uncemented group. The trend for more dependent accommodation in the uncemented group failed to reach statistical significance (p=0. 14). In conclusion, the cemented group faired significantly better than the uncemented group. Our findings suggest the advantages of cement outweigh the disadvantages, and we support the use of cemented hemiarthroplasty for the displaced intracapsular femoral neck fracture in the elderly patient
