Aims. The aim of this study was to compare the functional and radiological outcomes in patients with a displaced fracture of the hip who were treated with a cemented or a cementless femoral stem. Patients and Methods. A four-year follow-up of a randomized controlled study included 141 patients who underwent surgery for a displaced femoral neck fracture. Patients were randomized to receive either a cemented (n = 67) or a cementless (n = 74) stem at hemiarthroplasty (HA; n = 83) or total hip arthroplasty (THA; n = 58). Results. Early differences in functional outcome, assessed using the Harris Hip Score, the Short Musculoskeletal Functional Assessment score and EuroQol-5D, with better results in cemented group, deteriorated over time and there were no statistically significant differences at 48 months. Two (3%) patients in the cemented group and five (6.8%) in the cementless group underwent further surgery for a periprosthetic fracture. This difference was statistically significant (p = 0.4). No patient underwent further surgery for instability or infection between one and four years postoperatively. The mortality and the radiological outcomes were similar in both groups. Conclusion. Patients with a displaced femoral neck fracture treated with an arthroplasty using a cemented or cementless stem had good function and few complications up to four years postoperatively. However, due to the poor short-term functional outcomes in the cementless group, the findings do not support their routine use in the treatment of these elderly patients.

In a series of 450 patients over 70 years of age with displaced fractures of the femoral neck sustained between 1995 and 1997 treatment was randomised either to internal fixation or replacement. Depending on age and level of activity the latter was either a total hip replacement or a hemiarthroplasty. Patients who were confused or bed-ridden were excluded, as were those with rheumatoid arthritis. At ten years there were 99 failures (45.6%) after internal fixation compared with 17 (8.8%) after replacement. The rate of mortality was high at 75% at ten years, and was the same in both groups at all times. Patient-reported pain and function were similar in both groups at five and ten years. Those with successfully healed fractures had more hip pain and reduction of mobility at four months compared with patients with an uncomplicated replacement, and they never attained a better outcome than the latter patients regarding pain or function.

Primary replacement gave reliable long-term results in patients with a displaced fracture of the femoral neck.

Aims. For displaced femoral neck fractures (FNFs) in geriatric patients, there remains uncertainty regarding the effect of total hip arthroplasty (THA) compared with hemiarthroplasty (HA) in the guidelines. We aimed to compare 90-day surgical readmission, in-hospital complications, and charges between THA and HA in these patients. Methods. The Hospital Quality Monitoring System was queried from 1 January 2013 to 31 December 2019 for displaced FNFs in geriatric patients treated with THA or HA. After propensity score matching, which identified 33,849 paired patients, outcomes were compared between THA and HA using logistic and linear regression models. Results. The HA group had a lower incidence of 90-day surgical readmission than the THA group (odds ratio (OR) 0.75 (95% CI 0.68 to 0.83)). Meanwhile, the HA group had lower incidence of dislocation (OR 0.42 (95% CI 0.33 to 0.52)), aseptic loosening (OR 0.50 (95% CI 0.38 to 0.66)), and joint pain (OR 0.63 (95% CI 0.40 to 0.98)), but a higher incidence of periprosthetic fracture (OR 1.41 (95% CI 1.07 to 1.87)) for readmission, compared to the THA group. The incidence of in-hospital complications did not differ significantly between the two groups. Moreover, the HA group had lower mean charges than the THA group (47,578.29 Chinese Yuan (CNY) (SD 20,069.71) vs 57,641.00 CNY (SD 21,524.07)). Conclusion. When considering 90-day surgical readmission rate, in-hospital complications, and mortality, HA resulted in a significantly lower surgical readmission rate within 90 days compared to THA, despite the patients being older and having a higher Charlson Comorbidity Index.

Background. Systematic reviews disagree, but some recent studies have shown better function and less pain after operation with bipolar hemiarthroplasty compared to fixation by two screws in elderly patients operated for displaced femoral neck fractures. There is still uncertainty regarding the mortality associated with both procedures. Aim of the study. To investigate mortality and the risk factors for death among patients with displaced femoral neck fractures within the first three years after surgery, comparing operation with bipolar hemiarthroplasty (HA) and internal fixation (IF) by two screws. Methods. 12,313 patients (65 years or older) with displaced femoral neck fractures (Garden 3 and 4) operated either with IF by two screws (n = 3,436) or a bipolar HA (n = 8,877) were selected from the files of The Norwegian Hip Fracture Register 2005–2009. Mortality was assessed using Kaplan-Meier survival analysis and risk factors for death were studied using Cox-regression analysis. A power analysis showed the study sample to be sufficient to detect a difference in mortality of 3% at one and three years postoperatively. Results. The overall one-year mortality was 28% and three-year mortality was 50%. High age, male gender, cognitive impairment, increasing ASA score and delay in surgery >48 hours after injury were all associated with increased risk of death. For patients operated with a bipolar HA there was a statistically significant increased risk of death at day 30 (RR = 1.30, p<0.01), day 120 (RR = 1.15, p = 0.01), and day 240 (RR = 1.10, p<0.01) postoperatively compared to IF by two screws. At one year (RR = 1.04, p = 0.28) and three years (RR = 1.05, p = 0.16) postoperatively, we found no difference in the risk of death when comparing operation with bipolar HA to IF by two screws. Interpretation. The mortality for patients with displaced femoral neck fractures was considerable and dependent on age, gender, ASA score, cognitive status, and timing of surgery. Given the small magnitude of the difference in short-term mortality and no difference in one- and three-year mortality (or at least less than 3%) between the two treatment groups, we do not believe our findings should influence the choice of treatment method

Background. A well conducted randomised study found similar functional results for patients with displaced femoral neck fracture comparing operation with a modern uncemented bipolar hemiarthroplasty with a cemented bipolar hemiarthroplasty. The mortality associated with the two procedures has not been sufficiently investigated. Aim of study. To investigate the mortality and the risk factors for death among patients with displaced femoral neck fractures the first year after surgery, comparing operation with modern uncemented and cemented bipolar hemiarthroplasty (HA). Methods. 8,636 patients (65 years and older) with displaced femoral neck fractures (Garden 3 and 4) operated with a cemented (n = 6,907) or a uncemented bipolar HA (n = 1,729) were selected from the files of The Norwegian Hip Fracture Register 2005–2009. Mortality was assessed using Kaplan-Meier survival analysis and risk factors of death were investigated using Cox-regression analysis. A power analysis showed the study sample to be sufficient to detect a difference in mortality of 3% at one year postoperatively. Results. Overall mortality one year postoperatively was 27%. We found no difference in the risk of death when comparing operation with cemented with uncemented bipolar HA one year (RR = 0.97, p = 0.51), 240 days (RR = 1.00, p = 0.95), 120 days (RR = 1.04, p = 0.57), and 30 days (RR = 1.12, p = 0.23) postoperatively. However, 10 days postoperatively there was an increased risk of death for patients operated with cemented HA compared to those operated with uncemented bipolar HA (RR = 1.34, p = 0.03). High age, male gender, cognitive impairment, increasing ASA score, and delay in surgery >48 hours after injury were all associated with an increased risk of death one year postoperatively. Interpretation. The early increased risk of death for patients operated with a cemented HA might be caused by the bone cement implantation syndrome. Our results further indicate that the difference in mortality one year postoperatively is likely to be less than 3%

Introduction. Displaced femoral neck fractures in elderly are normally treated with 2 screws/pins (IF) or bipolar hemiarthroplasty (HA). The aim of this study was to compare IF and HA as treatment for displaced femoral neck fractures using reoperations and functional result (patient satisfaction, pain, and quality of life) as outcome. Material and Methods. From January 2005 all hip fractures in Norway are reported to the Norwegian Hip Fracture Register. At 4, 12, and 36 months postoperatively a questionnaire assessing satisfaction (VAS 0-100), pain (VAS 0-100), and quality of life (EQ-5D) is sent to the patients. To ensure more than 3 years follow-up, only patients operated in 2005 were included in the present study. Consequently 1,968 patients over 70 years of age operated with IF (n = 958) or HA (n = 1,010) due to displaced femoral neck fractures were included in the analyses on reoperations. Of these, 280 patients responded to all questionnaires and were included in the analyses on functional results (IF: n = 135, HA: n = 145). The patients remained in the same treatment group according to the intention-to-treat principle. Results. Through December 2008 496 (51.8%) patients had died in the IF group and 519 patients (51.4%) in the HA group. There were 238 (24.8%) reoperations performed in the IF group and 26 (2.6%) in the HA group. For the 280 patients included in the analyses on functional results, no preoperative differences were found between the two treatment groups concerning sex, comorbidity (ASA-class), cognitive dysfunction, and EQ-5Dindexscore. However, the patients in the HA group were older than the patients in the IF group (79.7 vs 77.7 years, p = 0.002). At all follow-ups, the HA-group were significant more satisfied with the result of the operation compared to the IF-group. The HA group reported less pain compared to the IF group after four months (18 vs 35, p<0.001) and after twelve months (16 vs 29, p<0.001). After 3 years no difference in pain between the two groups could be found. After four months the EQ 5Dindexscore was 0.69 in the HA-group and 0.58 in the IF-group (p<0.001), after twelve months 0.75 in the HA-group and 0.67 in the IF-group (p = 0.001), and after 3 years follow-up 0.74 in the HA-group and 0.71 in the IF-group (p<0.089). Discussion and Conclusion. There were more reoperations in the IF group than in the HA group. The superior functional results found in the HA group after 4 and 12 months were less evident after 3 years. For this frail patient group, a short rehabilitation period with minimized need for reoperations is important, and consequently, a hemiarthroplasty should be recommended as treatment for displaced femoral neck fractures

Introduction. Undisplaced femoral neck fractures have been given little attention in the literature. By using data from the Norwegian Hip Fracture Register, this study investigates risk for reoperation and the clinical results, including pain, patient satisfaction, and quality of life, after undisplaced femoral neck fractures in elderly patients. Material and Methods. Data on 4,468 patients over 70 years of age with undisplaced femoral neck fractures operated with internal fixation (IF) were compared to 10,289 patients with displaced femoral neck fractures treated with IF (n = 3,389) or bipolar hemiarthroplasty (n = 6,900). The evaluation was based on number of reported reoperations and patients' assessment (visual analogue scales concerning pain (0–100) and patient satisfaction (0–100), and quality of life (EQ-5D)) four and twelve months postoperatively. The patients were followed for 0–1 year. The Cox multiple regression model was used to construct adjusted survival curves. Subanalyses were performed on undisplaced femoral neck fractures to investigate different risk factors for reoperation. Results. The survival rate of implants after one year was 89% after screw fixation for undisplaced fractures, 79% after screw fixation for displaced fractures, and 97% after hemiarthroplasty for displaced fractures (Kaplan Meier). Adjusted for age, sex, ASA-classification, and cognitive function the displaced fractures operated with internal fixation had higher risk of reoperation compared to the undisplaced fractures operated with internal fixation (RR 1.92, 95% CI: 1.69–2.17; p<0.001). The displaced fractures operated with hemiarthroplasty had a lower risk of reoperation compared to the undisplaced fractures (RR 0.32, 95%CI: 0.27–0.38; p<0.001). Patients treated with IF for undisplaced fractures were more satisfied, had less pain, and higher quality of life compared to patients treated with IF after displaced fractures (p<0.05). The patients treated with bipolar hemiarthroplasty for displaced fractures had, however, the least pain, were most satisfied, and reported the highest quality of life. Discussion and Conclusion. The clinical outcome after undisplaced femoral neck fractures treated with screw fixation was better than the results of screw fixation for displaced fractures, but poorer than the clinical results for patients with displaced femoral neck fractures operated with a bipolar hemiarthroplasty. However, the differences in clinical outcome were smaller than what is considered to be of clinical importance. One year postoperatively screw osteosynthesis of undisplaced femoral neck fractures in elderly patients still seems to be a good alternative

Aims. The aim of this study was to describe variation in hip fracture treatment in Norway expressed as adherence to international and national evidence-based treatment guidelines, to study factors influencing deviation from guidelines, and to analyze consequences of non-adherence. Methods. International and national guidelines were identified and treatment recommendations extracted. All 43 hospitals routinely treating hip fractures in Norway were characterized. From the Norwegian Hip Fracture Register (NHFR), hip fracture patients aged > 65 years and operated in the period January 2014 to December 2018 for fractures with conclusive treatment guidelines were included (n = 29,613: femoral neck fractures (n = 21,325), stable trochanteric fractures (n = 5,546), inter- and subtrochanteric fractures (n = 2,742)). Adherence to treatment recommendations and a composite indicator of best practice were analyzed. Patient survival and reoperations were evaluated for each recommendation. Results. Median age of the patients was 84 (IQR 77 to 89) years and 69% (20,427/29,613) were women. Overall, 79% (23,390/29,613) were treated within 48 hours, and 80% (23,635/29,613) by a surgeon with more than three years’ experience. Adherence to guidelines varied substantially but was markedly better in 2018 than in 2014. Having a dedicated hip fracture unit (OR 1.06, 95%CI 1.01 to 1.11) and a hospital hip fracture programme (OR 1.16, 95% CI 1.06 to 1.27) increased the probability of treatment according to best practice. Surgery after 48 hours increased one-year mortality significantly (OR 1.13, 95% CI 1.05 to 1.22; p = 0.001). Alternative treatment to arthroplasty for displaced femoral neck fractures (FNFs) increased mortality after 30 days (OR 1.29, 95% CI 1.03 to 1.62)) and one year (OR 1.45, 95% CI 1.22 to 1.72), and also increased the number of reoperations (OR 4.61, 95% CI 3.73 to 5.71). An uncemented stem increased the risk of reoperation significantly (OR 1.23, 95% CI 1.02 to 1.48; p = 0.030). Conclusion. Our study demonstrates a substantial variation between hospitals in adherence to evidence-based guidelines for treatment of hip fractures in Norway. Non-adherence can be ascribed to in-hospital factors. Poor adherence has significant negative consequences for patients in the form of increased mortality rates at 30 and 365 days post-treatment and in reoperation rates.

Aims

This study aimed to describe practice variation in the use of total hip arthroplasty (THA) for older patients with femoral neck fracture and to determine the association between patient, surgeon, and institution factors and treatment with THA.

Introduction. Many patients with displaced intracapsular femoral neck fractures (IFNF) are treated with hemiarthroplasty (HA) which has been shown superior to internal fixation(IF) the first year after injury. Long term results, however, are sparse. Methods. A total of 222 consecutive patients above 60 years, including mentally disabled, with IFNF were randomized to either internal fixation with two parallel screws or hemiarthroplasty, and operated by the surgeon on call. After 5 years, 68 of the 70 surviving patients accepted a follow-up visit. The reviewers were blinded for initial treatment. Results. The mean survival of the groups was similar. Only 12 (of 31) patients in the IF group still had their native hip joint at five years. Harris Hips score was 70.0 ± 3.5 and 70.4 ± 3.4 in the IF and hemiarthroplasty group, respectively (p=0.9). Eq5d index was in the IF group 0.56 ±0.08 and in the hemiarthroplasty group 0.45 ± 0.7 (p=0.3). Barthel ADL index was split into good function (score 95 or 100) and reduced function (score below 95). Of the patients in the internal fixation group, 42 % reported good function, corresponding number in the arthroplasty group was 52 % (p=0.4). After two years, there were 44 (42%) hips with a major reoperation in the IF group and 11 (10%) in the hemiarthroplasty group. Between 2 and 5 years, there were two new major reoperations (both in the IF group; avascular necrosis; deep wound infection). Discussion. Hemiarthroplasty has predictable and good long time surgical results. These findings emphasize that arthroplasty is better than IF as treatment for displaced intracapsular femoral neck fractures

Background. In Sweden approximately 6000 patients yearly sustain displaced femoral neck fractures. During the last decade there has been a shift towards more arthroplasties at the expense of internal fixation. In 2008 approximately 75% of the dislocated femoral neck fractures in Sweden were treated with arthroplasties. Those patients are typically elderly and frail and the vast majority of them receive hemiarthroplasties. In 2005 a national hemiarthroplasty registration was established as part of the Swedish Hip Arthroplasty Register (SHAR). Material & Method. The SHAR aims to register all hemiarthroplasties performed in Sweden, including primary and salvage procedures. Surgical and patient details are recorded and re-operations are registered. Results. 21.346 hemiarthroplasties were recorded from 2005 through 2009. The most common diagnosis, acute fracture of the femoral neck, increased from 91.3 to 94.3 percent during this period. The most commonly used stems (i.e. the Lubinus SP II and the Exeter stems) accounted for 68.3 percent of the implants. In total 743 patients (3,6%) underwent additional surgery and the most common reason for this was dislocation. The strongest risk factors for re-operation and revision (Cox regression analysis) were hemiarthroplasty due to failed internal fixation (rr 2.1, 95%CI 1.7–2.7) and uncemented stem (2.0, CI 1.5–2.6). Even when only modern uncemented implants are analyzed (i.e. exclusion of Austin-Moore) we can still see an increased risk of any re-operation(1.8, CI 1.3–2.5) and re-operation due to periprosthetic fracture (3.8, CI 2.0–7.1). Bipolar hemiarthroplasty heads also increased the risk of re-operation, especially due to dislocation (1.4, CI 1.1–1.8). The most used bipolar head (Variocup) has no increased risk of re-operation compared to all other bipolar heads generally, but an increased risk of re-operation due to dislocation (1.7, CI 1.2–2.4). Anterolateral surgical approach (Gammer and Hardinge) decreased the risk of re-operation due to dislocation (0.63, CI 0,53-0.83). Other risk factors are male gender and age above 75 years. During the period the use of monoblock type implants decreased from 17.8 to 0.9 percent. Use of uncemented implants decreased from 10.4 percent in 2005 to 3.0 percent in 2009 and the number of procedures performed with anterolateral approach increased from 46.7 to 55.9 percent. Conclusion. The SHAR have identified risk factors for re-operation and subsequently some important changes have been seen in choice of implant and fixation. We conclude that the results from the hemiarthroplasty registration have a large impact on the methods and implants chosen by the Swedish orthopaedic surgeons and therefore is an important tool in the continuing effort for improving the patient care

Aims

The aim of this study was to compare the early postoperative mortality and morbidity in older patients with a fracture of the femoral neck, between those who underwent total hip arthroplasty (THA) and those who underwent hemiarthroplasty.

Aims

The aim of this study was to assess the association of mortality and reoperation when comparing cemented and uncemented hemiarthroplasty (HA) in hip fracture patients aged over 65 years.

Aims

The aim of this study was to investigate the potentially increased risk of dislocation in patients with neurological disease who sustain a femoral neck fracture, as it is unclear whether they should undergo total hip arthroplasty (THA) or hemiarthroplasty (HA). A secondary aim was to investgate whether dual-mobility components confer a reduced risk of dislocation in these patients.

Aims

Deep surgical site infection (SSI) remains an unsolved problem after hip fracture. Debridement, antibiotic, and implant retention (DAIR) has become a mainstream treatment in elective periprosthetic joint infection; however, evidence for DAIR after infected hip hemiarthroplaty is limited.

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

Aims

Hip fractures in patients < 60 years old currently account for only 3% to 4% of all hip fractures in England, but this proportion is increasing. Little is known about the longer-term patient-reported outcomes in this potentially more active population. The primary aim is to examine patient-reported outcomes following isolated hip fracture in patients aged < 60 years. The secondary aim is to determine an association between outcomes and different types of fracture pattern and/or treatment implants.

Aims

The primary aim of this prognostic study was to identify baseline factors associated with physical health-related quality of life (HRQL) in patients after a femoral neck fracture. The secondary aims were to identify baseline factors associated with mental HRQL, hip function, and health utility.

Aims

This study describes and compares the operative management and outcomes in a consecutive case series of patients with dislocated hemiarthroplasties of the hip, and compares outcomes with those of patients not sustaining a dislocation.

The aim of this study was to determine the comorbid risk factors for failure in young patients who undergo fixation of a displaced fracture of the femoral neck. We identified from a prospective database all such patients ≤ 60 years of age treated with reduction and internal fixation. The main outcome measures were union, failure of fixation, nonunion and the development of avascular necrosis.

There were 122 patients in the study. Union occurred in 83 patients (68%) at a mean follow-up of 58 months (18 to 155). Complications occurred in 39 patients (32%) at a mean of 11 months (0.5 to 39). The rate of nonunion was 7.4% (n = 9) and of avascular necrosis was 11.5% (n = 14). Failures were more common in patients over 40 years of age (p = 0.03). Univariate analysis identified that delay in time to fixation (> 24 hours), alcohol excess and pre-existing renal, liver or respiratory disease were all predictive of failure (all p < 0.05). Of these, alcohol excess, renal disease and respiratory disease were most predictive of failure on multivariate analysis.

Younger patients with fractures of the femoral neck should be carefully evaluated for comorbidities that increase the risk of failure after reduction and fixation. In patients with a history of alcohol abuse, renal or respiratory disease, arthroplasty should be considered as an alternative treatment.
