Aims

In UK there are around 76,000 hip fractures occur each year 10% to 15% of which are undisplaced intracapsular. There is considerable debate whether internal fixation is the most appropriate treatment for undisplaced fractures in older patients. This study describes cannulated hip screws survivorship analysis for patients aged ≥ 60 years with undisplaced intra-capsular fractures.

Introduction. Intracapsular hip fractures in young adults are treated with internal fixation, often as a surgical emergency to reduce the vascular insult to the femoral head. Avascular necrosis and non-union often require revision surgery. Methods. A prospective trauma database was retrospectively searched from 1. st. August 2008 to 31. st. December 2010. Intracapsular hip fracture admissions to the Regional Trauma Centre, in adults under sixty-five years, were studied. Ninety-eight intracapsular fractures internally fixed with sliding hip screw underwent radiographic review for quality of fixation, and evidence of complications at a mean of thirteen months. Co-morbid medical conditions and quality of fixation were assessed for association with revision rates. Results. Avascular necrosis developed in eighteen fractures, and seven proceeded to non-union. Seventeen of ninety-eight fractures underwent revision to total hip arthroplasty. Three individuals were deceased at final review. Six of thirty-four fractures (18%) fixed within twelve hours of injury required revision, compared with eleven of sixty-four (17%) fixed after twelve hours. None of the four fractures fixed within six hours required revision, although this was not statistically significant (p=0.32). Revision was required for three of six individuals with chronic respiratory disease (50%) excluding asthma, one of two with rheumatoid arthritis (50%), and three of six with varus reduction (50%), and each were significant on multiple regression. Residual translation and eccentric screw placement approached significance on chi-squared analysis. Only two of twenty (10%) fractures fixed using an additional anti-rotation screw required revision. Conclusions. Internal fixation of intracapsular hip fractures within twelve hours in young adults did not statistically reduce revision rates. Accurate reduction and internal fixation is paramount, and anti-rotation screws may reduce complication rates. Certain co-morbid conditions predict revision, and should be taken into consideration when selecting the primary operative procedure

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.

Aims: To explore potential predictors of functional outcome one year after the injury in elderly women who sustained a displaced intracapsular hip fracture and who were treated with internal fixation, hemiarthroplasty, or total hip arthroplasty. Methods: Eighty-four women aged > 50 years were enrolled on a consecutive basis in this one-year prospective cohort study reflecting standard day-to-day clinical practice. The main outcome measure was the Rapid Disability Rating Scale version-2 applied at hospital discharge and one year later. Results: The total hip arthroplasty group was younger (p< 0.001) and had a better functional status than the internal fixation or hemiarthroplasty groups (p< 0.001) at hospital discharge. One year later, the best function was still observed in the total arthroplasty group, but the differences were small and failed to achieve the level of statistical significance. During that one-year period, walking ability or mobility did not change significantly after total hip arthroplasty, but a significant proportion of the women developed cognitive impairment, including mental confusion, uncooperativeness, and depression (p< 0.001). Overall, the most significant predictors of poor functional status one year after fracture were increasing age (p=0.005), living in an institution at time of injury (p=0.034), and poor functional status at discharge (p< 0.001). Conclusions: In elderly women with a displaced intra-capsular hip fracture, total hip arthroplasty is associated with a functional benefit within the first months after surgery. However, the extent to which this functional benefit is maintained over time, is less clear. Our results support the need for randomised clinical trials among elderly women with a displaced intracapsular hip fracture to quantify the extent to which the early functional benefit of total hip arthroplasty is maintained in the long run or compromised by progressive cognitive impairment and other negative determinants of functional outcome

Evidence suggests as little as 32percnt; of those with a displaced intracapsular hip fracture who meet the NICE eligibility criteria currently undergo a total hip replacement (THR). The reason for this discrepancy is not clear. This study therefore set out to examine the reasons behind this lack of adherence to these guidelines through the use of a questionnaire to current Trauma & Orthopaedic surgery consultants across Scotland. An invitation to take part in the survey was distributed through the Scottish Committee for Orthopaedics & Trauma (SCOT) email address list. A series of 10 questions were designed to determine the background of participants, their experience at performing hip fracture surgery (including THR) and their thoughts regarding its use in the hip fracture setting. Results were collated at the end of the study period and quantitatively analysed where possible. There were 91 responses in total. 53percnt; of individuals said they would offer those meeting the NICE criteria a THR less than 76percnt; of the time. The most commonly used alternative was a cemented bipolar hemiarthroplasty (51percnt;). Hip surgeons were more likely to perform or supervise THR for hip fracture than non-hip surgeons (p<0.0001). There were a wide variety of reasons why people would not offer a THR including dislocation rate, technical complexity and inadequate evidence for use. Overall this study highlights current trends and barriers in the provision of THR to hip fracture patients. This knowledge can be used to ascertain research priorities to maximise the quality of care in this setting

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

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.

Introduction

Intracapsular fractures of the femoral neck in young adults are a surgical emergency. Recent literature reviews have questioned whether the timing of surgery reduces the incidence of avascular necrosis, non-union and revision.

A study was performed to determine how many patients met a 12-hour target for operative fixation with this injury. Possible sources of delay to theatre were reviewed.

The aim of this retrospective study was to evaluate the failure rate among different fixation devices for undisplaced fracture neck of femur. All 52 patients with Garden I and II hip fractures who underwent surgery in a teaching hospital in London from January 2007 to June 2012 were included. Electronic patient records were accessed to collect the patient data.

There were 52% females and the mean age of patients was 70 years. Thirty patients had cannulated screws, 18 – dynamic hip screw (DHS) with de-rotation screw and 4 had DHS alone. Initial results showed that 36% patients had re-operation. 7(77%) had total hip replacement and 1(11%) had metal work removal. The reason for revision was failure of fixation in 8 (88%) and avascular necrosis in 1 (11%). There was significantly higher failure rate in the DHS with derotation screw group (50%) compared to the cannulated screw group (35%) and the DHS alone group (0%). Average time to planned revision was 11.1 months.

Traditionally undisplaced intra capsular hip fractures are treated by in-situ fixation using different devices. Biomechanically DHS with de-rotation screw achieves better rotational and axial stability compared to other fixation devices. However, our study showed a higher failure rate in this group. Inability to achieve a perfectly parallel screw position seems to be a significant factor responsible for high failure. Higher failure rates with fixation may boost the role of replacement arthroplasty as one off surgical treatment in elderly patients.

In Displaced Intracapsular Hip Fractures (ICHF) in young active patients, preservation of the femoral head and its blood supply are of high importance and urgent surgical treatment with anatomic reduction and internal fixation is the preferred intervention. Due to the strong varus displacement shear forces exerted across the hip, there are relatively high complication rates after fixation. There is no consensus regarding the optimal fixation device or technique. This retrospective study compared closed reduction internal fixation method using cannulated cancellous screw (CCS) with the Targon Femoral Neck (TFN) hip fixed angle screw. Data regarding, gender, operational data, duration of surgery, complications, NAS (Numerical Analogue Scale) pain score, Modified Harris Hip Score (MHHS) and SF-12 scores were retrieved for patients younger than 65 with displaced ICHF. Eighty-two patients were included in the study, 30 patients treated with CCS were compared to 52 patients treated with TFN. Fracture configuration (Garden and Pauwel classifications), mean time to surgery and complication rate did not differ significantly. Operative time did differ significantly between groups (CCS 56 minutes, TFN 92 minutes, p<0.001). At final follow-up the CCS group reported less pain (NAS 2.3 vs 3.5, p< 0.049) and better Mental Health Composite score of SF-12 (p=0.017) compared to the TFN group. Complication rates for the treatment of displaced ICHF with TFN and CCS showed no significant differences; however, the functional outcomes, as presented by the NAS and Mental Health Composite score of SF-12, showed superiority for CCS treatment. As this fixation method is related to reduce costs, we suggest CCS for the treatment of displaced ICHF in the young population.

To compare the incidence of Bone Cement Implantation Syndrome (BCIS), perioperative thromboembolic events and mortality in patients with a femoral neck fracture (FNF) treated with a hybrid total hip arthroplasty (THA) without intraoperative unfractioned heparin (UFH) (control) versus a group of patients who received intraoperative UFH before femoral cementation.

We retrospectively reviewed 273 patients who underwent hybrid THA due to a FNF between 2015 and 2020. We compared a group of 139 patients without intraoperative administration of UFH (group A) with 134 patients who underwent THA with intraoperative administration of 10 UI/kg UFH (group B). UFH indication was dependent on surgeon´s preference. We assessed the advent of BCIS and 30-day thromboembolic events, as well as 90-day and 1-year mortality.

BCIS was observed in 51 cases (18%), defined as Grade 1 (O2% < 94% or fall in systolic blood pressure of 20% to 40%) in 37 cases (13%) and Grade 2 (O2% < 88% or fall in systolic blood pressure of > 40%) in 14 cases (5%). Forty-seven BCIS (35%) were observed in the group that received UFH and 4 BCIS (3%) in the control group (p <0.001). Multivariate regression model showed that intraoperative UFH (OR=18, CI95% 6–52) and consumption of oral anticoagulants (OR=3.3, CI95% 1–10) had an increased risk of developing BCIS. Five patients developed a pulmonary embolism in the UFH group while 2 patients presented this complication in the non UFH group (p=0.231). Mortality was 1% for both groups at 90 days PO (p= 0.98), 2% at 1 year for group A and 3% for group B (p =0.38).

BCIS in our series was 18%. We found a paradoxically 17-fold significant increase of BCIS with the use of UFH. Heparin did not prevent BCIS, thromboembolic events and mortality in this group of patients.

NICE Guidelines suggest patients should be offered a Total Hip Replacement (THR) rather than Hemiarthroplasty for a displaced intracapsular hip fracture. We investigated outcomes of patients aged 40–65 who received a THR or Hemiarthroplasty following a traumatic intracapsular hip fracture and had either high-risk (Group 1) or low-risk (Group 2) alcohol consumption (>14 or <14 units/week respectively). This was a retrospective study (April 2008 – December 2018) evaluating patients who underwent THR or Hemiarthroplasty in Greater Glasgow and Clyde. Atraumatic injuries, acetabular fractures, patients with previous procedures on the affected side and those lost to follow up were excluded. Analysis of length of admission, dislocation risk, periprosthetic fractures, infection risk, and mortality was conducted between both cohorts. Survival time post-operatively of Group 1 patients with a THR (61.9 months) and Hemiarthroplasty (42.3 months) were comparable to Group 2 patients with a THR (59 months) and Hemiarthroplasty(42.4 months). Group 1 patients with THR had increased risk of dislocation (12.9%; p=0.04) compared to those that received Hemiarthroplasty (2.5%). Group 1 Hemiarthroplasty patients had increased wound infection risk (11.6%) compared to Group 2 (3.7%). In conclusion, we found that amongst our population the life expectancy of a post-operative patient was short irrespective of whether they had high or low-risk alcohol consumption. A hip fracture may represent increased frailty in our study population. The Group 1 THR cohort presented a higher risk of hip dislocation and periprosthetic fracture. With this in mind, Hemiarthroplasty is a more cost-effective and shorter operation which produces similar results

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.

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

Introduction. The National Institute for Health and Care Excellence (NICE) currently recommends the use of total hip replacement (THR) for displaced intracapsular hip fractures in cognitively competent patients and who were independently mobile with the maximum use of one stick prior to the injury. Method. We conducted a prospective cross sectional study of the management of hip fractures within a defined geographic region in the North East of England to assess current practice and variation in provision of THR for displaced intracapsular hip fracture. Results. A total of 879 patients with hip fracture, admitted to eight acute trauma units were included in this study. 169 of 462 patients with displaced intracapsular hip fractures fulfilled the NICE criteria for THR. THR was performed for only 49 of the eligible patients (29%). There was significant variation in THR provision between the eight units (0% THR usage to 50% usage) (p<0.001). In the patients with a displaced intracapsular fracture, there were statistically significant differences in the age, ASA grade, AMTS and pre-injury walking ability between patients who underwent fixation, THR or hemiarthroplasty (all p≤0.05). There was an increased chance of undergoing THR if a patient was 77 years (the median age for the THR eligible cohort) or younger compared to older than 77 years (RR=7.9, 95%CI 2.8–22.0, p<0.001) and if the patients were either ASA grade 1 or 2 compared to ASA grade 3 (RR=2.7, 95%CI 1.0–7.3, p=0.06). The reasons given by the treating surgeon for not performing THR in eligible patients were multifactorial. Conclusion. There is significant variation in the provision of THR for eligible hip fracture patients which is influenced by both patient demographics and also by the unit to which the patient is admitted

Background. Total hip arthroplasty (THA) is increasingly used for active patients with displaced intracapsular hip fractures. Dislocation rates in this cohort remain high postoperatively compared to elective practice, yet it remains unclear which patients are most at risk. The aim of this study was to determine the dislocation rate for these patients and to evaluate the contributing patient and surgeon factors. Methods. A five-year retrospective analysis of all patients receiving THA for displaced intracapsular hip fractures from 2013–18 was performed. Data was collected from the institutions' hip fracture database, including data submitted to the National Hip Fracture Database (NHFD). Cox regression analysis and log-rank tests were implemented to evaluate factors associated with THA dislocation. Patient age, sex, ASA grade, surgeon seniority, surgical approach, femoral head diameter and acetabular cup type were all investigated as independent factors. Results. A total of 196 patients, with a mean age of 72 (range 49–90), received THA for hip fracture between 2013–18. A posterior approach, using standard cemented acetabular components and a 28mm femoral head, was used in 133 cases (72%). Fourteen dislocations (7%) were observed during this period, with 5 patients requiring revision surgery. Of these dislocations, all were performed through posterior approaches with standard cemented cups. 28mm femoral heads were used in all cases except one, which used a 32mm femoral head. In Cox regression analysis, ASA grade, but not age or sex, was significantly associated with dislocation (hazard ratio = 4.5; 95% confidence interval 2.0–10.0; p<0.001). On log rank testing no statistically, significant association was found between dislocation and surgeon grade (p=0.85), surgical approach (p=0.31), femoral head size (p=0.85) or cup type (p=0.30). Discussion. This study demonstrates an increased risk of dislocation following THA for hip fracture with higher ASA grades. It may be appropriate to offer more stable implants to this cohort of patients

The February 2013 Trauma Roundup. 360 . looks at: the risk of ankle fractures; absorbable implants; minimally invasive heel fracture fixation; pertrochanteric fractures; arthroplasty and intracapsular hip fractures; and extensor mechanism disruption

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.

Introduction: Despite its common occurrence there is still controversy regarding the choice of treatment for the displaced intracapsular hip fracture in the elderly patient. Aim: To compare internal þxation and hemiar-throplasty in a prospective randomised controlled trial. Method: 455 patients aged over 70 years with a displaced intracapsular hip fracture were randomised to either hemiarthroplasty or internal þxation. Results: Internal þxation has shorter length of anaesthesia (p< 0.0001), lower operative blood loss (p< 0.0001) and lower transfusion requirements (p< 0.0001). Additional surgical procedures were required in 90 patients (39.8%) treated by internal þxation and 12 patients (5.2%) in the arthroplasty group. There was no statistical difference in mortality at one year (p=0.91), however there was a trend to improved survival for the older less mobile patients treated by internal þxation. There was no statistical difference in pain and mobility. Limb shortening was more common after internal þxation (p=0.004). Conclusion: We recommend that displaced intracapsular fractures in the elderly should generally be treated by hemiarthro-plasty, but internal þxation may be appropriate for the frail less mobile patient

Continued controversy exists between cemented versus uncemented hemiarthroplasty for an intracapsular hip fracture. To assist in resolving this controversy, 400 patients were randomised between a cemented polished tapered stem hemiarthroplasty and an uncemented Furlong hydroxyapatite coated hemiarthroplasty. Follow-up was by a nurse blinded to the implant used for up to three years from surgery. Results indicate no difference in the pain scores between implants but a tendency to an improved regain of mobility for those treated with the cemented arthroplasty (1.2 score versus 1.7 at 6 months, p=0.03). There was no difference in early mortality but a tendency to a higher later mortality for the uncemented implants (29% versus 24% at one year, p=0.3). Later peri-prosthetic fracture was more common in the uncemented group (3% versus 1.5%). Revision arthroplasty was required for 2% of cemented cases and 3% of uncemented cases. Surgery for an uncemented hemiarthroplasty was 5 minutes shorter but these patients were more likely to need a blood transfusion (14% versus 7%). Three patients in the cemented group had a major adverse reaction to bone cement leading to their death. These results indicated that a cemented stem hemiarthroplasty give marginally improved regain of mobility in comparison to a contemporary uncemented hemiarthroplasty. An uncemented hemiarthroplasty still has a place for those considered to be at a high risk of bone cement implantation syndrome
