Patient satisfaction, pain, and quality of life 4 months after displaced femoral neck fractures: a comparison of 663 fractures treated with internal fixation and 906 with bipolar hemiarthroplasty reported to the Norwegian Hip Fracture Register

Rehabilitation of Frail Older Adults after Hip Fracture Surgery: Predictors for the Length of Geriatric Rehabilitation Stay at a Skilled Nursing Home

Background: Approximately 50% of older patients hospitalized for hip fractures are admitted to a geriatric rehabilitation department at a skilled nursing home. Given the wide variation in rehabilitation stay lengths, predicting the length of stay upon hospital discharge would help manage patients' recovery expectations and create appropriate therapy schedules. Existing literature on length of stay predictors included both acute hospital and in-hospital rehabilitation phases or involved small sample sizes. The present study aims to identify predictors for the length of geriatric rehabilitation stay in skilled nursing homes for older patients after hip fracture surgery upon hospital discharge. Methods: This retrospective cohort study was conducted from 1 October 2017 to 1 July 2023, including 561 patients. Potential predictors of the length of geriatric rehabilitation stay were first tested univariately, with variables showing p < 0.15 entered into a multivariate forward linear regression model. Results: This model identified the following independent predictors of a longer length of geriatric rehabilitation stay: Functional Ambulation Categories (FACs) 0 (B = 29.9, 95% CI 24.1-35.7), 1 (B = 18.0, 95% CI 11.8-24.2), 2 (B = 12.0, 95% CI 7.1-17.0), or 3 (B = 3.6, 95% CI -1.2-9.4) at hospital discharge vs. FAC 4, living independently with home care services (B = 5.9, 95% CI 2.5-9.3) or in a residential home prior to the hip fracture (B = 0.2, 95% CI -7.4-7.8) vs. living independently without home care services, non- or partial weight-bearing mobilization vs. full weight-bearing mobilization (B = 15.4, 95% CI 8.5-22.2), internal fixation vs. hemiarthroplasty (B = 4.7, 95% CI 1.4-7.9), in-hospital delirium (B = 7.0, 95% CI 2.2-11.7), and in-hospital heart failure (B = 7.9, 95% CI 0.5-15.3). The explained variance was 32.0%. Conclusions: This study identified FAC at hospital discharge, premorbid living situation, postoperative weight-bearing protocol, surgery type, in-hospital delirium, and in-hospital heart failure as independent predictors of the length of geriatric rehabilitation stay. Future investigations are needed to identify additional predictors, such as cognitive functioning, to better predict the length of geriatric rehabilitation stay upon hospital discharge.

Movement Patterns in Older Adults Recovering From Hip Fracture

The aim of this study was to quantify physical activity and sedentary behavior in older adults recovering from hip fracture and to identify groups based on movement patterns. In this cross-sectional cohort study, older adults (≥70 years) were included 3 months after surgery for proximal femoral fracture. Patients received an accelerometer for 7 days. Demographics and outcomes related to physical function, mobility, cognitive functions, quality of life, and hip fracture were assessed. In total, 43 patients with sufficient accelerometer wear time were included. Across all groups, participants engaged in very low levels of physical activity, spending an average of 11 hr/day in prolonged sedentary behavior. Based on the extracted components from a principal component analysis, three groups with substantial differences in levels of physical activity and sedentary behavior could be distinguished.

Quality of Life After Hip Fracture Surgery in the Elderly: A Cross-Sectional Study

Purpose Hip fractures are common and serious injuries as they lead to high mortality and morbidity and have a significant effect on patients' lives. Additionally, these injuries have substantial socioeconomic consequences for patients' quality of life, their families, and healthcare systems. The aim of this study is to assess the quality of life (QoL) in patients after hip fracture surgery. Methods This study involved a cross-sectional survey between February 2016 and December 2019, with a sample of 199 patients who suffered a hip fracture and were treated at a tertiary care teaching hospital. The participants completed the EuroQol 5-Dimensions 5-Levels (EQ-5D-5L) questionnaire. Pearson's chi-squared test, independent sample t-test, and Pearson's correlation coefficient (r) were used in the analysis. Results We found that there is a statistically significant association between age and having problems with mobility (p=0.023), self-care (p<0.001), and usual activity (p=0.029). In addition, increased age was significantly associated with decreased EuroQol Visual Analog Scale (EQ-VAS) scores (r=-0.213, p=0.003). We also found a statistically significant association between gender and self-care, as males were more likely to report having problems with self-care when compared to females (OR: 3.63; CI 95%: 1.77-7.44; p<0.001). Conclusion Mobility, self-care, and usual activity were the most significantly affected quality of life measures and were more apparent in older age groups. Patients should be educated about the possibility of a decline in their QoL and the role of postoperative rehabilitation in improving patients' mobility. Periodic QoL screening should be done as early as possible to detect any further decrease. Future research should standardize postoperative interview intervals to improve QoL evaluation and include a control group.

Simple Minimally Invasive Method to Reduce Valgus-Impacted and Tilted Femoral Neck Fractures without Soft Tissue or Cartilage Injury: Radiological and Clinical Results

OBJECTIVE

This is a rare study comparing the radiological and functional outcomes of fixation after reduction with in situ fixation group using Femoral Neck System (FNS). The aim of this study was to introduce a simple, innovative, minimally invasive method to reduce valgus-impacted and tilted femoral neck fractures without soft tissue or cartilage injury.

METHODS

A retrospective comparative analysis of 46 patients between May 2020 and February 2022 was performed. In the control group, 23 patients underwent in situ fixation without reduction. In the study group, another 23 patients were managed by fixation after reduction using a percutaneous pull-out technique with a full threaded Steinmann pin. Caput-collum-diaphysis (CCD) angle, tilt, and femoral neck shortenings were compared between the two groups. In addition, Harris Hip Score (HHS) was evaluated and compared at 1 year after surgery. Basically, independent samples t-test was used to compare radiological and functional results.

RESULTS

Patients' initial valgus and tilt angles were not significantly different between the groups (n.s.). However, the CCD and tilt angles measured immediately and at one year postoperatively were significantly different between the groups (p < 0.05). Regarding femoral neck shortening, shortening in the three directions, the x, y, and z vectors, was significantly less in the reduction group immediately postoperatively and at 1 year post-surgery (p < 0.05). The mean HHS at 1 year postoperatively was 79.7 ± 8.4 in the in situ fixation group and 87.9 ± 6.6 in the reduction groups, and there was a significant difference (p < 0.05).

CONCLUSION

The pull-out method with a threaded Steinmann pin to reduce valgus-impacted and tilted femoral neck fracture is safe and effective for accomplishing anatomical restoration. This may achieve successful bone union and maintain the femoral neck length and original tilt without nearby soft tissue or cartilage injury.

Direct anterior versus antero-lateral approach in hip joint hemiarthroplasty

BACKGROUND

Femoral neck fractures are common injuries in the elderly and represent a major source of morbidity and mortality. Due to the benefits, bipolar hip hemiarthroplasty (BHH) is a popular method to treat. The purpose of this study is to evaluate the functional and radiographic outcomes for BHH comparing the direct anterior approach (DAA) to the anterolateral approach (ALA) to the hip joint.

METHODS

We used a prospective, randomized observational study design, where we enrolled 83 patients at a level-I-trauma center presenting with indication for BHH. We followed up the participants at defined intervals over a period of 1 year. The follow-up examinations were carried out at defined time intervals for a period of 1 year. Calculations were performed with Statistical Package for Social Sciences (SPSS) 21.0.

RESULTS

Concerning postoperative pain sensation, the anterior group had statistically significantly decreased pain levels at one (p = 0.02), seven (p = 0.04) and 14 days (p = 0.02) following the intervention when compared to the ALA sample. The postoperative modified Barthel-Index showed a statistically significant difference on the first postoperative day at the anterior group.

CONCLUSION

Although we compared two minimally invasive approaches, our results shows a statistically significant difference in pain intensity and mobility for the early postoperative period using the direct anterior approach.

Does Surgical Approach Influence Complication Rate of Hip Hemiarthroplasty for Femoral Neck Fractures? A Literature Review and Meta-Analysis

Background: Femoral neck fractures are an epidemiologically significant issue with major effects on patients and health care systems, as they account for a large percentage of bone injuries in the elderly. Hip hemiarthroplasty is a common surgical procedure in the treatment of displaced femoral neck fractures. Several surgical approaches may be used to access the hip joint in case of femoral neck fractures, each with its own benefits and potential drawbacks, but none of them has consistently been found to be superior to the others. This article aims to systematically review and compare the different approaches in terms of the complication rate at the last follow-up. Methods: an in-depth search on PubMed/Scopus/Web of Science databases and a cross-referencing search was carried out concerning the articles comparing different approaches in hemiarthroplasty and reporting detailed data. Results: A total of 97,576 hips were included: 1030 treated with a direct anterior approach, 4131 with an anterolateral approach, 59,110 with a direct lateral approach, and 33,007 with a posterolateral approach. Comparing the different approaches, significant differences were found in both the overall complication rate and the rate of revision surgery performed (p < 0.05). In particular, the posterolateral approach showed a significantly higher complication rate than the lateral approach (8.4% vs. 3.2%, p < 0.001). Furthermore, the dislocation rate in the posterolateral group was significantly higher than in the other three groups considered (p < 0.026). However, the posterolateral group showed less blood loss than the anterolateral group (p < 0.001), a lower intraoperative fractures rate than the direct anterior group (p < 0.035), and shorter mean operative time than the direct lateral group (p < 0.018). Conclusions: The posterolateral approach showed a higher complication rate than direct lateral approach and a higher prosthetic dislocation rate than the other three types of surgical approaches. On the other hand, patients treated with posterolateral approach showed better outcomes in other parameters considered, such as mean operative time, mean blood loss and intraoperative fractures rate. The knowledge of the limitations of each approach and the most common associated complications can lead to choosing a surgical technique based on the patient's individual risk.

Does anatomical type of proximal hip fracture affect rehabilitation outcomes among older adults?

BACKGROUND AND PURPOSE

Numerous studies have detailed the potential benefits of inpatient geriatric rehabilitation for older adults with hip fractures. However, data regarding effect of fracture type (femoral neck, intertrochanteric, or subtrochanteric) on rehabilitation outcomes are limited. This study assessed whether the anatomical type of proximal hip fracture affects rehabilitation outcomes among disabled older adults.

METHODS

A population-based study was conducted comparing all patients with a recent hip fracture who were admitted to a geriatric rehabilitation facility in Israel. Data were collected retrospectively from an electronic database during a 5-year period (2014-2019). The Functional Independence Measure (FIM) was used to assess physical and cognitive function at admission and discharge.

RESULTS

The analyses included 624 older adults with hip fractures. We found significant differences in motor FIM score at admission, as patients with femoral neck fracture performed better than patients with intertrochanteric and subtrochanteric fracture did. The disparity in motor FIM score remained consistent through discharge, with all groups achieving a median gain of 14 points. Within one month of rehabilitation, about a third of all patients achieved a higher functional level.

CONCLUSIONS

Patients with femoral neck fracture have better motor ability than do those with intertrochanteric and subtrochanteric fractures, which were retained throughout the course of rehabilitation; yet, the level of improvement remained similar. Clinicians should be aware of such differences in functional ability when discussing goals of care with older adults with hip fractures and consider them when implementing individual rehabilitation programs .

[Development of the inpatient quality of care of surgically treated patients with a proximal femoral fracture in North Rhine-Westphalia : Analysis of 61,249 treatment courses based on data from external inpatient quality assurance]

BACKGROUND AND OBJECTIVE

Every year in Germany over 100,000 people, mostly of older age, suffer a proximal femoral fracture. Increasing case numbers in connection with an aging population and a relatively large number of concomitant diseases requiring treatment make everyday care more difficult. It is therefore of great importance to observe the quality of care for these patients using relevant quality parameters in order to be able to derive implications for everyday treatment practice.

MATERIAL AND METHODS

The data of the external inpatient quality assurance from North Rhine-Westphalia for the years 2007-2008 and 2017-2018 were analyzed and the time periods compared. In addition, based on the documented secondary diagnosis and other influencing parameters, a risk adjustment was carried out with the aid of a logistic regression model with respect to the outcomes of general and surgical complications and mortality. Both osteosynthetically and endoprosthetically treated patients were taken into account. A total of 61,249 cases were included in the study.

RESULTS

Positive developments could be observed in the area of surgical complications and wound infections with decreases of 1.2% and 0.8%, respectively. Patients with cardiovascular diseases had a particularly poor outcome. Here, improvements in the subcategory of cardiovascular events were found for general complications. The mortality remained unchanged at 6%. Operative activity on the weekends increased significantly. Patients whose hospital admission was related to the weekend did not show an increased risk of complications or mortality. Although the proportion of patients who were operated on after more than 48 h was reduced from 11.4% to 8.2%, the operation (> 24 h) was still delayed in 26.8% of cases.

CONCLUSION

Against the background of increasing performance demands on the healthcare system, the results document improvements in some central areas of inpatient treatment. Nevertheless, the development of strategies for the further reduction of the preoperative waiting times in a medically justifiable manner is required. Internal concomitant diseases have a decisive influence on patient outcome. Thus, an adequate treatment of the multimorbid patient collective is to be established in everyday practice on the basis of close cooperation between geriatric traumatology and geriatric internal medicine departments.

Diagnostik und Therapie aus der Patientenperspektive - PROMs in der Chirurgie

Die zunehmend an Bedeutung gewinnenden Patient reported Outcome and Experience Measures (PROMs/PREMs) können in allen chirurgischen Disziplinen zusätzlich zu den klassischen harten Endpunkten wie z. B. Überlebenskurven und Implantatestandzeiten wichtige Informationen zu Qualitätsindikatoren oder Entscheidungshilfen zu konkurrierenden Therapieverfahren liefern. Dies gilt ebenso für die Evaluation neuer Therapiekonzepte wie für Vergleiche klassisch offener Zugangswege und minimalinvasiver bzw. endoskopischer Verfahren z. B. im Hinblick auf geringere Zugangsmorbidität und schnellere Rehabilitation vs. höherem Komplikationsrisiko, aber auch der Risiko-Nutzen-Bewertung der Verlängerung der Lebenszeit einerseits auf Kosten einer Beeinträchtigung der Lebensqualität andererseits.

Diesem Zusatznutzen steht ein notwendiger Ressourceneinsatz (Personal- und Sachkosten für Postversand oder für eine Onlineerhebung in Form von Entwicklungs-, Bereitstellungs- oder Lizenz- und Servicekosten) gegenüber, der sich nur bedingt beeinflussen lässt (z. B. Portokosten für eine Vollerhebung vs. repräsentative Stichprobe). Die zentrale Voraussetzung für den erfolgreichen Einsatz von PROMs und PREMs ist jedoch, dass geeignete, sprachlich und inhaltlich validierte Erhebungsinstrumente verfügbar sind oder durch einen Validierungsprozess zur Verfügung gestellt werden können.

Für den Einsatz von PROMs bei konkurrierenden Therapieansätzen findet sich bereits eine Reihe von Beispielen, die wertvolle Unterstützung bieten und sich im Klinikalltag etabliert haben. So können sie bei belastenden Therapieansätze in der chirurgischen Tumortherapie bei Entscheidungen über ein verbessertes Überleben bei starker Belastung vs. dem Erhalt oder sogar Zugewinn an Lebensqualität unterstützen. In der onkologischen Mammachirurgie steht die Lebensqualität bei brusterhaltendem Vorgehen häufig der Überlebenszeit bezogen auf das TU-Stadium bei Ablation gegenüber. Ebenso gilt es bei Prostatakarzinompatienten, immer wieder zwischen invasiver Therapie und Verlaufsbeobachtung (Überleben vs. Inkontinenz und Potenzstörungen) zu entscheiden. In der Orthopädie/Unfallchirurgie gibt es bei einer Reihe von Eingriffen häufig eine Alternative, z. B. Sprunggelenkendoprothesen vs. Arthrodesen oder inverse Schulterprothesen vs. Osteosynthese bei schultergelenknahen Humerusfrakturen.

Aber auch bei der Evaluation neuer Therapiekonzepte (z. B. der subjektive Aspekt einer früheren Wiedererlangung der Selbstständigkeit durch Einführung neuer Nachbehandlungskonzepte/sog. Fast-Track-Reha) sind PROMs und PREMS wichtige Werkzeuge.

Bipolar hemiarthroplasty may reduce cerebrovascular accidents and improve early weight-bearing in the elderly after femoral neck fracture

Cerebrovascular accidents (CVA) in the elderly population after femoral neck fracture remain great concern for physicians. Specifically, surgical fixation techniques, such as bipolar hemiarthroplasty (HA) and internal fixation play a significant role in influencing the occurrence of postoperative CVA in the elderly population.In order to identify 2 cohorts, we used a rigid selection process based on our institution's database. The cohorts were comprised of a HA cohort and a cannulated screw cohort, of which underwent femoral neck surgery, performed by 3 fellowship trained surgeons from 2003 to 2014. Risk factors were documented and measured, including Coumadin use and hypertension, and postoperative complications such as CVA and death rate were also recorded. A P-value of <.05 was determined to be statistically significant.A power analysis was performed and achieved a power of 0.95. We found a non-significant reduction in CVA for bipolar HA (3.6% CVA vs 0.0% in the non-CVA group, P = .48) and a non-significant increase in CVA for cannulated screw use (7.6% CVA vs 14.4% in the non-CVA group, P = .11). In addition, we found a significant difference in terms of weight-bearing status at 6-weeks postoperatively (0.95 vs 2.0, P < .0001), favoring the bipolar HA group.Among the advantages of bipolar HA surgery, surgeons should consider its value in reducing the occurrence of postoperative CVA. Furthermore, patients who underwent bipolar HA had improved weight-bearing status postoperatively compared with cannulated screw fixation.

A Simple Diagnosis-Related Groups-Based Reimbursement System Is Cost Ineffective for Elderly Patients With Displaced Femoral Neck Fracture Undergoing Hemiarthroplasty in Beijing

Displaced femoral neck fractures (FNF) in the elderly are a major public health concern that necessitates hemiarthroplasty (HA) as the mainstay treatment option. Diagnosis-Related Groups (DRG) are a patient classification system that categorizes patients based on the resources expended on them. The first objective of this study was to evaluate if a simplified DRG-based reimbursement system in Beijing would lower total HA treatment costs for elderly patients with displaced FNF. In addition, we aimed to determine how age, gender, year of admission, length of in-hospital stay, and the Charlson index affected total treatment costs. This retrospective study included 513 patients from the Peking Union Medical College Hospital. The patients were diagnosed with unilateral displaced femoral neck fractures and had HA. Medical information was gathered, including baseline demographic and clinical data, as well as treatment costs. Patients were classified into two groups: those who spent more than the predetermined cut-off cost and those who did not. The cost did not include the use of a bipolar prosthesis. Data from the two groups were compared, and multiple regression analysis models were constructed. The median total cost of treatment was ¥49,626 ($7,316). The majority of the patients (89.7%; 460/513) were categorized as exceeding the cost cut-off. Multiple linear regression analysis revealed that total treatment cost was positively correlated with age (p < 0.01) and the duration of in-hospital stay (p < 0.01) but not with gender (p = 0.160) or the Charlson index (p = 0.548). On implementing the DRG-based reimbursement system, the overall treatment costs increased by ¥21,028 ($3,099) (p < 0.01). The implementation of simplified DRG-prospective payment systems did not result in a significant reduction in total treatment costs for elderly patients with FNF who underwent HA in Beijing. The overall cost of treatment was associated with several factors, including age, length of hospitalization, and year of admission.

The Quality of Life, Patient Satisfaction and Rehabilitation in Patients With a Low Energy Fracture-Part III of an Observational Study

Introduction

Due to the aging population the incidence of Low Energy Fractures (LEF) increases. LEF have high mortality and morbidity rates and often cause elderly to lose independence. Patient-reported outcomes, such as Quality of Life (QoL) and patient satisfaction (PS) are needed to evaluate treatment, estimate cost-benefit analyses, and to improve clinical decision-making and patient-centered care.

Objective

The primary goal was to evaluate QoL and PS in patients with LEF, and to compare QoL scores to the community dwelling population. Second, we observed the amount and type of physiotherapy (PT) sessions the patients conducted.

Methods

A single-center cohort study was conducted in Switzerland. Patients between 50 and 85 years, who were treated in the hospital for LEF, were followed 1 year after initial fracture. Data on QoL were obtained through the Euroqol-5-Dimension questionnaire-3-Level (EQ-5D-3L) and the EQ VAS (visual analog scale). PS was measured by a VAS on satisfaction with treatment outcome. Data on PT sessions, mobility and use of analgesics were collected by telephone interviews and written surveys. Results were compared between the different fracture locations and subgroup analyses were performed for age categories.

Results

411 patients were included for analysis. The median scores of the EQ-5D-3L index-VAS and PS were 0.90 (0.75-1.0), 90 (71.3-95) and 100 (90-100). Significant differences in all scores were found between fracture location (P < .05), with hip fracture patients and patients with a malleolar fracture scoring lowest in all measures. QoL index in hip fracture patients was 0.76 (0.70-1.00), QoL VAS 80 (70-90), and PS 95 (80-100). Median amount of PT sessions in all patients was 18 (9-27) and a significant difference was found between fracture locations. Patients with a fracture of the humerus received the highest amount of PT sessions 27 (18-36), hip fracture patients had a median of 18 (9-27) sessions.

Conclusion

At follow-up, QoL throughout all patients with a LEF was comparable to a normal population. Remarkably, though hip fracture patients seem to suffer from a clinically relevant loss of QoL, they received fewer PT sessions and performed fewer long-lasting home training than patients with a humerus fracture. Intensive, progressive rehabilitation with a high frequency of supervised training is recommended after hip fracture. The low frequency of PT sessions found in this study is unsatisfying. In hip fracture patients and in patients with a malleolar fracture, especially when aged over 75 years, more efforts are required to improve rehabilitation and subsequently QoL.

[The Treatment Exit Options for Uveitis (TOFU) Registry: Involving Patients in the Generation of Evidence]

Uveitis comprises a group of rare diseases characterised by intraocular inflammation which may cause vision impairment and blindness and mostly affects people of working age. Non-infectious uveitis involving the posterior pole or the entire eye is often treated with different immunomodulating or disease-modifying anti-rheumatic drugs (DMARDs). However, the evidence on long-term management strategies and reduction/termination of treatment is limited. To help develop treatment exit strategies for patients with quiescent uveitis on long-term DMARD treatment, the Treatment Exit Options for Non-infectious Uveitis registry was initiated by the German ophthalmological society. A key aspect of the registry is active participation of patients (patient-reported outcomes, PROs). In a pilot study involving members of patient organizations, a combination of questionnaires covering vision- and general health-related quality of life, adherence to treatment, productivity and effects of treatment were evaluated. As the pilot study showed coverage of relevant patient-related aspects of the disease and its effect on daily life, the evaluated questionnaires were implemented in the registry's patient module. The registry including the patient module uses the electronic data capture (EDC) software REDCap (Version 9, Vanderbilt University, USA). By involving patients in both conceptualization and ongoing data collection, the TOFU registry emphasizes the patients' perspectives, and the inclusion of patient-relevant evidence for such as the development of guidelines and treatment recommendations is ensured.

Internal fixation versus hip arthroplasty in patients with nondisplaced femoral neck fractures: short-term results from a geriatric trauma registry

Purpose

To determine whether internal fixation (IF) or hip arthroplasty (HA) is associated with superior outcomes in geriatric nondisplaced femoral neck fracture (FNF) patients.

Methods

Data from the Registry for Geriatric Trauma of the German Trauma Society (ATR-DGU) were analyzed (IF Group 449 and HA Group 1278 patients). In-hospital care and a 120-day postoperative follow-up were conducted. Primary outcomes, including mobility, residential status, reoperation rate, and a generic health status measure (EQ-5D score), and the secondary outcome of mortality were compared between groups. Multivariable analyses were performed to assess independent treatment group associations (odds ratios, ORs) with the primary and secondary end points.

Results

Patients in the HA group were older (83 vs. 81 years, p < 0.001) and scored higher on the Identification of Seniors at Risk screening (3 vs. 2, p < 0.001). We observed no differences in residential status, reoperation rate, EQ-5D score, or mortality between groups. After adjusting for key covariates, including prefracture ambulatory capacity, the mobility of patients in the HA group was more frequently impaired at the 120-day follow-up (OR 2.28, 95% confidence interval = 1.11–4.74).

Conclusion

Treatment with HA compared to treatment with IF led to a more than twofold increase in the adjusted odds of impaired ambulation at the short-term follow-up, while no significant associations with residential status, reoperation rate, EQ-5D index score, or mortality were observed. Thus, IF for geriatric nondisplaced FNFs was associated with superior mobility 120 days after surgery. However, before definitive treatment recommendations can be made, prospective, randomized, long-term studies must be performed to confirm our findings.

Midterm results of revision total hip arthroplasty for migrated bipolar hemiarthroplasty in patients with hip osteoarthritis using cementless cup with the rim-fit technique

PURPOSE

The results of reamed bipolar hemiarthroplasty (BHA) in patients with hip osteoarthritis (OA) are reported to be unfavorable. Acetabular reaming for sufficient bony coverage caused bipolar head migration into the superomedial direction, and most patients required revision surgeries. Several methods are applicable to treat decreased bone stock. This study aimed to investigate the midterm results of revision surgeries using the cementless cup with the rim-fit technique.

METHODS

Between 1996 and 2014, acetabular revision surgeries using the cementless cup with the rim-fit technique were performed in 86 hips (74 patients). We evaluated radiographic outcomes, including positional change of the rotation center of the artificial femoral head, presence of implant loosening, and filling of the initial gap. We also evaluated clinical outcomes, including the Harris hip score (HHS), and postoperative complications.

RESULTS

The average positional changes from BHA to prerevision surgeries were 8.0 mm superiorly and 4.1 mm medially. The average changes from prerevision to postrevision surgeries were 3.7 mm inferiorly and 2.4 mm laterally. No implant loosening was found in all cases; the initial gap between the acetabular host bone and the acetabular cup was filled in 53 (93%) among 57 hips. The average HHS improved from 65.9 before revision surgeries to 83.8 in the latest follow-up. Dislocation and postoperative periprosthetic fracture occurred in two and five hips, respectively; no cases required rerevision surgeries.

CONCLUSION

There were favorable midterm results of the revision total hip arthroplasty for migrated BHA in patients with hip OA using cementless cup with the rim-fit technique.

Mortality and revision risk after femoral neck fracture: comparison of internal fixation for undisplaced fracture with arthroplasty for displaced fracture: a population-based study from Danish National Registries

Background and purpose - Hemiarthroplasty has lower reoperation frequency and better mobilization compared with internal fixation (IF) in patients with undisplaced femoral neck fractures (FNF), which might translate into lower mortality. In this population-based cohort study we compare the risk of mortality and reoperation in undisplaced FNF treated with IF and displaced FNF treated with arthroplasty in patients older than 70 years old. We assume that, per se, there is no difference in mortality risk between patients with a displaced and an undisplaced FNF.Patients and methods - Hip fracture patients were identified in the Danish Multidisciplinary Hip Fracture Registry during 2005-2015. Data on medication, comorbidities, reoperation, and mortality were retrieved from other Danish medical databases. IF and arthroplasty patients were compared with regards to mortality and reoperation up to 5 years postoperatively. We calculated hazard ratios (HR) with 95% confidence intervals (CI) adjusting for relevant confounders.Results - We included 19,260 FNF treated with arthroplasty and 10,337 FNF with IF. There was an increased risk of mortality for arthroplasty within 30 days, HR 1.3 (95% CI 1.3-1.4), compared with IF but not after 1 and 5 years. Arthroplasty patients had adjusted HRs for reoperation of 0.8 (0.8-0.9) within 1 year, 0.8 (0.7-0.9) within 2 years, and 0.8 (0.8-0.9) within 5 years postoperatively compared with IF.Interpretation - Patients treated for a displaced FNF with arthroplasty had a higher risk of 30-day mortality compared with patients who had an undisplaced FNF treated with IF. It has to be considered that there were baseline differences in the groups but there was no difference in mortality risk up to 5 years post-surgery. Concerning reoperation, patients with a displaced FNF treated with arthroplasty had a lower risk of reoperation compared with IF for undisplaced FNF.

Internal Fixation Versus Arthroplasty for the Treatment of Nondisplaced Femoral Neck Fractures in the Elderly: A Systematic Review and Meta-Analysis

OBJECTIVE

To compare the outcomes of elderly patients with nondisplaced and minimally displaced femoral neck fractures treated with internal fixation versus arthroplasty.

DATA SOURCES

A comprehensive search of the MEDLINE, Embase, and central databases was conducted through June 25, 2019.

STUDY SELECTION

Studies were included if the sample population was (1) 60 years of age or older, (2) had nondisplaced or minimally displaced (Garden I or II) femoral neck fractures, and (3) if the study compared internal fixation versus arthroplasty. Only full-text English manuscripts were included. The primary outcome was reoperation. Secondary outcomes included mortality, patient-reported outcomes, length of hospital stay, infection, and blood transfusions.

DATA EXTRACTION

Two authors independently extracted data from the included studies. Each study was independently evaluated for quality using the Cochrane risk of bias assessment.

DATA SYNTHESIS

Of the 1597 identified articles, 4 manuscripts met the eligibility criteria with a total of 579 patients (236 treated with hemiarthroplasty and 343 treated with internal fixation). Patients treated with arthroplasty had a significantly lower risk of reoperation when compared with those treated with internal fixation [relative risk: 0.30 (95% CI, 0.16-0.55, P < 0.01)]. There was no significant difference detected in 1-year mortality risk between the 2 treatment groups.

CONCLUSIONS

In elderly patients with nondisplaced and minimally displaced femoral neck fractures, treatment with hemiarthroplasty may reduce the relative risk of reoperation by 70% when compared with internal fixation.

Validation of orthopaedic surgeons' assessment of cognitive function in patients with acute hip fracture

BACKGROUND

About one fourth of patients with hip fracture have cognitive impairment. These patients are at higher risk of surgical and medical complications and are often excluded from participating in clinical research. The aim of the present study was to investigate orthopaedic surgeons' ability to determine the cognitive status of patients with acute hip fracture and to compare the treatment given to patients with and without cognitive impairment.

METHODS

The cognitive function of 1474 hip fracture patients reported by the orthopaedic surgeons to the nationwide Norwegian Hip Fracture Register was compared with data registered in quality databases in two hospitals with orthogeriatric service on the same patients. Cognitive function registered in the quality databases was determined either by the short form of the Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE) or by pre-fracture diagnosis of dementia. The information registered in the quality databases was defined as the reference standard. Cognitive function in the Norwegian Hip Fracture Register was reported as: Chronic cognitive impairment? "Yes", "Uncertain" or "No" by the orthopaedic surgeons. Sensitivity, specificity, negative and positive predictive values for chronic cognitive impairment reported to the Norwegian Hip Fracture Register by the orthopaedic surgeons was calculated. Baseline data and treatment of hip fractures in patients with and without cognitive impairment in the Norwegian Hip Fracture Register were compared.

RESULTS

Orthopaedic surgeons reported chronic cognitive impairment in 31% of the patients. Using documented dementia or IQCODE > 4.0 as the reference, this assessment of cognitive impairment by the orthopaedic surgeons had a sensitivity of 69%, a specificity of 90%, a positive predictive value of 78%, and a negative predictive value of 84% compared to information registered in the two hospital quality databases. There were no differences in type of hip fracture or type of surgical treatment by cognitive function.

CONCLUSION

The treatment of hip fractures was similar in patients with chronic cognitive impairment and cognitively well-functioning patients. The surgeons had an acceptable ability to identify and report chronic cognitive impairment in the peri-operative period, indicating that the Norwegian Hip Fracture Register is a valuable resource for future registry-based research also on hip fracture patients with chronic cognitive impairment.

Minimally invasive anterior muscle-sparing versus a transgluteal approach for hemiarthroplasty in femoral neck fractures-a prospective randomised controlled trial including 190 elderly patients

BACKGROUND

The relevance of femoral neck fractures (FNFs) increases with the ageing of numerous societies, injury-related decline is observed in many patients. Treatment strategies have evolved towards primary joint replacement, but the impact of different approaches remains a matter of debate. The aim of this trial was to evaluate the benefit of an anterior minimally-invasive (AMIS) compared to a lateral Hardinge (LAT) approach for hemiarthroplasty in these oftentimes frail patients.

METHODS

Four hundred thirty-nine patients were screened during the 44-months trial, aiming at the evaluation of 150 patients > 60 yrs. of age. Eligible patients were randomised using an online-tool with completely random assignment. As primary endpoint, early mobility, a predictor for long-term outcomes, was evaluated at 3 weeks via the "Timed up and go" test (TUG). Secondary endpoints included the Functional Independence Measure (FIM), pain, complications, one-year mobility and mortality.

RESULTS

A total of 190 patients were randomised; both groups were comparable at baseline, with a predominance for frailty-associated factors in the AMIS-group. At 3 weeks, 146 patients were assessed for the primary outcome. There was a reduction in the median duration of TUG performance of 21.5% (CI [- 41.2,4.7], p = 0.104) in the AMIS-arm (i.e., improved mobility). This reduction was more pronounced in patients with signs of frailty or cognitive impairment. FIM scores increased on average by 6.7 points (CI [0.5-12.8], p = 0.037), pain measured on a 10-point visual analogue scale decreased on average by 0.7 points (CI: [- 1.4,0.0], p = 0.064). The requirement for blood transfusion was lower in the AMIS- group, the rate of complications comparable, with a higher rate of soft tissue complications in the LAT-group. The mortality was higher in the AMIS-group.

CONCLUSION

These results, similar to previous reports, support the concept that in elderly patients at risk of frailty, the AMIS approach for hemiarthroplasty can be beneficial, since early mobilisation and pain reduction potentially reduce deconditioning, morbidity and loss of independence. The results are, however, influenced by a plethora of factors. Only improvements in every aspect of the therapeutic chain can lead to optimisation of treatment and improve outcomes in this growing patient population.

Hip Fractures and the Bundle: A Cost Analysis of Patients Undergoing Hip Arthroplasty for Femoral Neck Fracture vs Degenerative Joint Disease

BACKGROUND

The purpose of this study is to determine whether episode Target Prices in the Bundled Payment for Care Improvement (BPCI) initiative sufficiently match the complexities and expenses expected for patients undergoing hip arthroplasty for femoral neck fracture (FNF) as compared to hip degenerative joint disease (DJD).

METHODS

Claims data under BPCI Model 2 were collected for patients undergoing hip arthroplasty at a single institution over a 2-year period. Payments from the index hospitalization to 90 days postoperatively were aggregated by Medicare Severity Diagnosis-Related Group (469 or 470), indication (DJD vs FNF), and categorized as index procedure, postacute services, and related hospital readmissions. Actual episode costs and Target Prices were compared in both the FNF and DJD cohorts undergoing hip arthroplasty to gauge the cost discrepancy in each group.

RESULTS

A total of 183 patients were analyzed (31 with FNFs, 152 with DJD). In total, the FNF cohort incurred a $415,950 loss under the current episode Target Prices, whereas the DJD cohort incurred a $172,448 gain. Episode Target Prices were significantly higher than actual episode prices for the DJD cohort ($32,573 vs $24,776, P < .001). However, Target Prices were significantly lower than actual episode prices for the FNF cohort ($32,672 vs $49,755, P = .021).

CONCLUSION

Episode Target Prices in the current BPCI model fall dramatically short of the actual expenses incurred by FNF patients undergoing hip arthroplasty. Better risk-adjusting Target Prices for this fragile population should be considered to avoid disincentives and delays in care.

Surgical Approaches and Hemiarthroplasty Outcomes for Femoral Neck Fractures: A Meta-Analysis

BACKGROUND

The lateral approach (LA), posterior approach (PA), and anterior approach (AA) are conventional surgical access routes for hemiarthroplasty in proximal femoral fractures. This meta-analysis assesses and compares the outcomes and attempts to identify the best approach for hemiarthroplasty in the treatment of proximal femoral fractures.

METHODS

An electronic search was performed from inception to October 25, 2017, for comparative studies including at least 2 of the conventional approaches. Outcomes including operation time, surgical blood loss, perioperative fractures, wound infections, dislocations, and hospital length of stay were plotted in forest plots.

RESULTS

Twenty-one eligible studies were selected including 3 randomized, controlled trials, 7 prospective and 11 retrospective cohort studies. The odds ratio (OR) for dislocations was significantly higher for the PA compared with the AA (OR, 2.61; 95% confidence interval [CI], 1.26 to 5.43; P = .01) and the LA (OR, 2.90; 95% CI, 1.63 to 5.14; P = .0003). The PA had a higher risk of reoperation compared to the AA (OR, 1.25; 95% CI, 1.12 to 1.41; P < .0001). No significant differences were found concerning perioperative fractures, wound infections, and hospital length of stay. Some studies suggest a better short-term functional outcome using the AA compared to the PA.

CONCLUSION

The PA for hemiarthroplasty in proximal femoral fractures poses an increased risk of dislocation and reoperation compared to the LA and AA. There are no evident advantages of the PA and its routine use for fracture-related hemiarthroplasty should be questioned.

A prospective study with ten years follow-up of two-hundred patients with proximal femoral fracture

BACKGROUND

The proximal femoral fracture is one of the most common injuries in the elderly. Nevertheless, no results beyond the second year post surgery have been reported in the literature. Therefore, the purpose of this study was to evaluate any revision and mortality within 10 years follow-up as well as the walking ability of still alive patients.

METHODS

A total of 200 consecutive patients were included. A prospective database was first used to collect the demographic data. Exactly ten years after the surgery, a final evaluation was conducted by telephone for every patient. Any revision, any contralateral as well as other fractures and the date of death were recorded. For all patients who were still alive, the mobility score according to Parker was also surveyed.

RESULTS

The average age was 79.0 years (SD: 12.5); women were affected at higher numbers (73.5%). The total surgical revision rate was 17.5% (35/200), due in particular to hematoma (9×) or infection (7×). A surgical revision later than two years was only needed in three patients (1.5%). The risk of another fracture caused by a fall was 19% (38/200), most often a contralateral femoral fracture (22/200; 11%) that happened on average 51.9 months (1-97) after the initial surgery. The risk of a contralateral femoral fracture was 15.4% (22/143) in patients who survived the first year post surgery. The postoperative mortality was 1, 2, 5 and 10 years or 23.5%, 32.5%, 55% as well as 81.5%, respectively. An average Parker's mobility score of 6.3 points (0-9) was determined for the 37 patients (18.5%) who were still alive at the time of the follow-up.

CONCLUSION

The long-term study showed that revision surgery was only required in 3/200 patients (1.5%) beyond the second year of that surgery. On the other hand, more than half of all patients had already passed away five years after the initial surgery. The exact incidence of a contralateral femoral fracture was 11.9%, climbing to 15.4% if the patient survived at least one year. Nearly every fifth patient experienced another fall resulting in a severe fracture requiring treatment during the long-term course.

Quality of life and psychological consequences in elderly patients after a hip fracture: a review

Fractures due to fragility of the bone around the hip joint have become a major public health issue, presenting with an increasing incidence due to the growth of the elderly population. The purpose of this review was to evaluate the impact of hip fractures on the quality of life (QoL), health status (HS), functioning, and psychological parameters, and factors influencing the outcome and the appropriate interventions for improvement of elderly patients. A systematic electronic search of the relevant literature was carried out using the CINAHL, Cochrane, EMBASE, Medline (OvidSP), and PubMed databases spanning the time period from their establishment up to January 2017. Forty-nine randomized controlled trials or prospective cohort studies reporting the QoL and psychological outcomes were assessed by using standardized questionnaires. Patients with a hip fracture who were older than 65 years, were included in the analysis. In the majority of elderly patients, the hip fracture seriously affected physical and mental functioning and exerted a severe impact on their HS and health-related QoL (HRQoL). Moreover, most of the patients did not return to prefracture levels of performance regarding both the parameters. The levels of mental, physical, and nutritional status, prior to the fracture, comorbidity, and female gender, in addition to the postoperative pain, complications, and the length of hospital stay, were the factors associated with the outcome. Psychosocial factors and symptoms of depression could increase pain severity and emotional distress. For the displaced femoral neck fractures, the treatment with total hip arthroplasty or hemiarthroplasty, when compared to the treatment with internal fixation, provided a better functional outcome. Supportive rehabilitation programs, complemented by psychotherapy and nutritional supplementation prior to and after surgery, provided beneficial effects on the HS and the psychosocial dimension of the more debilitated patients’ lives. Lack of consensus concerning the most appropriate HRQoL questionnaires to screen and identify those patients with more difficulties in the psychosocial functions, demonstrates the necessity for further research to assess the newer outcome measurement tools, which might improve our understanding for better care of patients with hip fractures.

Prospective comparison of the anterior and lateral approach in hemiarthroplasty for hip fractures: a study protocol

Background

The Direct Anterior Approach (DAA) is an alternative approach to the currently most used Lateral Approach (LA) for hip replacement in femoral neck fracture patients. Compared to the LA, the DAA minimizes soft tissue damage. Sparing muscle tissue may facilitate early and improved postoperative mobility. It may also be associated with fewer complications, increased quality of life and lower 1-year mortality. The aim of this study is to compare postoperative complications, hip function and patient mobility after hemiarthroplasty via the anterior or lateral approach following a displaced femoral neck fracture.

Methods

138 elderly patients with displaced femoral neck fractures will be operated using either the direct anterior approach or the lateral approach for a hemiarthroplasty in a single centre, prospective, comparative cohort study. The choice of surgical approach will depend on the expertise of the trauma surgeon on call. The primary outcome of this study will be the functionality of the hip after surgery measured using the Harris Hip Score during routine outpatient check-ups. Secondary outcomes include surgical and non-surgical complication rates, admission time, postoperative pain, rehabilitation time, performance in activities of daily living, health-related quality of life measured, cognitive function and balance.

Discussion

Many approaches are known for hip replacement arthroplasty in trauma patients with little consensus on the preferred method. Identifying the best approach facilitating an adequate and fast recovery could optimize patient independence and quality of life and minimize rehabilitation costs, morbidity and mortality rates. The study design will reflect daily clinical practice and aims to present an accurate depiction of clinical outcomes.

Posterior approach compared to direct lateral approach resulted in better patient-reported outcome after hemiarthroplasty for femoral neck fracture

Background and purpose - Hemiarthroplasty (HA) is the most common treatment for displaced femoral neck fractures in many countries. In Norway, there has been a tradition of using the direct lateral surgical approach, but worldwide a posterior approach is more often used. Based on data from the Norwegian Hip Fracture Register, we compared the results of HA operated through the posterior and direct lateral approaches regarding patient-reported outcome measures (PROMs) and reoperation rate. Patients and methods - HAs due to femoral neck fracture in patients aged 60 years and older were included from the Norwegian Hip Fracture Register (2005-2014). 18,918 procedures were reported with direct lateral approach and 1,990 with posterior approach. PROM data (satisfaction, pain, quality of life (EQ-5D), and walking ability) were reported 4, 12, and 36 months postoperatively. The Cox regression model was used to calculate relative risk (RR) of reoperation. Results - There were statistically significant differences in PROM data with less pain, better satisfaction, and better quality of life after surgery using the posterior approach than using the direct lateral approach. The risk of reoperation was similar between the approaches. Interpretation - Hemiarthroplasty for hip fracture performed through a posterior approach rather than a direct lateral approach results in less pain, with better patient satisfaction and better quality of life. The risk of reoperation was similar with both approaches.

The Frank Stinchfield Award : Total Hip Arthroplasty for Femoral Neck Fracture Is Not a Typical DRG 470: A Propensity-matched Cohort Study

BACKGROUND

Hip fractures are a major public health concern. For displaced femoral neck fractures, the needs for medical services during hospitalization and extending beyond hospital discharge after total hip arthroplasty (THA) may be different than the needs after THA performed for osteoarthritis (OA), yet these differences are largely uncharacterized, and the Medicare Severity Diagnosis-Related Groups system does not distinguish between THA performed for fracture and OA.

QUESTIONS/PURPOSES

(1) What are the differences in in-hospital and 30-day postoperative clinical outcomes for THA performed for femoral neck fracture versus OA? (2) Is a patient's fracture status, that is whether or not a patient has a femoral neck fracture, associated with differences in in-hospital and 30-day postoperative clinical outcomes after THA?

METHODS

The National Surgical Quality Improvement Program (NSQIP) database, which contains outcomes for surgical patients up to 30 days after discharge, was used to identify patients undergoing THA for OA and femoral neck fracture. OA and fracture cohorts were matched one-to-one using propensity scores based on age, gender, American Society of Anesthesiologists grade, and medical comorbidities. Propensity scores represented the conditional probabilities for each patient having a femoral neck fracture based on their individual characteristics, excluding their actual fracture status. Outcomes of interest included operative time, length of stay (LOS), complications, transfusion, discharge destination, and readmission. There were 42,692 patients identified (41,739 OA; 953 femoral neck fractures) with 953 patients in each group for the matched analysis.

RESULTS

For patients with fracture, operative times were slightly longer (98 versus 92 minutes, p = 0.015), they experienced longer LOS (6 versus 4 days, p < 0.001), and the overall frequency of complications was greater compared with patients with OA (16% versus 6%, p < 0.001). Although the frequency of preoperative transfusions was higher in the fracture group (2.0% versus 0.2%, p = 0.002), the frequency of postoperative transfusion was not different between groups (27% versus 24%, p = 0.157). Having a femoral neck fracture versus OA was strongly associated with any postoperative complication (odds ratio [OR], 2.8; 95% confidence interval [CI], 2.1-3.8]; p < 0.001), unplanned readmission (OR, 1.8; 95% CI, 1.0-3.2; p = 0.049), and discharge to an inpatient facility (OR, 1.7; 95% CI, 1.4-2.0; p < 0.001).

CONCLUSIONS

Compared with THA for OA, THA for femoral neck fracture is associated with greater rates of complications, longer LOS, more likely discharge to continued inpatient care, and higher rates of unplanned readmission. This implies higher resource utilization for patients with a fracture. These differences exist despite matching of other preoperative risk factors. As healthcare reimbursement moves toward bundled payment models, it would seem important to differentiate patients and procedures based on the resource utilization they represent to healthcare systems. These results show different expected resource utilization in these two fundamentally different groups of patients undergoing hip arthroplasty, suggesting a need to modify healthcare policy to maintain access to THA for all patients.

Risk factors of avascular necrosis of the femoral head and fixation failure in patients with valgus angulated femoral neck fractures over the age of 50 years

INTRODUCTION

The aim of our study was to identify the risk factors for avascular necrosis of the femoral head (AVN) and fixation failure (FF) after screw osteosynthesis in patients with valgus angulated femoral neck fractures.

PATIENTS AND METHODS

We conducted a retrospective study of 308 patients (mean age, 72.5 years, range, 50-97 years), with a mean follow-up of 21.4 months (range, 12-64 months). The risk for failure in treatment (FIT) associated with patient- and fracture-related factors was evaluated by logistic regression analyses.

RESULTS

FIT was identified in 32 cases (10.3%): 22 cases (7.1%) of AVN and 10 cases (3.2%) of FF. Initial valgus tilt>15° (p=0.023), posterior tilt>15° (p=0.012), and screw sliding distance (p=0.037) were significantly associated with FIT. FIT occurred in 7 patients (5.2%) with B1.2.1 fractures and 17 patients (48.6%) with B1.1.2 fractures (p<0.001). The odds of FIT were 17-fold higher in patients with initial valgus and posterior tilts>15° (B1.1.2) compared to patients with <15° of tilt in both planes (B1.2.1).

CONCLUSION

The severity of initial deformity predicts AVN and FF in patients with valgus angulated femoral neck fractures. Patients with an initial valgus and posterior tilt>15° are reasonable candidates for primary arthroplasty due to high risk of FIT.

Factors associated with the course of health-related quality of life after a hip fracture

INTRODUCTION

The number of hip fracture patients is expected to grow the forthcoming decades. Knowledge of the impact of the fracture on the lives of elderly could help us target our care. The aim of the study is to describe HRQoL (Health-Related Quality of Life) after a hip fracture and to identify factors associated with the course of HRQoL in the first postoperative year.

MATERIALS AND METHODS

335 surgically treated hip fracture patients (mean age 79.4 years, SD 10.7, 68 % female) were included in a prospective observational cohort. HRQoL was measured with the SF-12 Health Survey, composed of the Physical and a Mental Component Summary Score (PCS, MCS), at admission (baseline) and at 3 and 12 months postoperatively. Eleven predefined factors known to be associated with the course of HRQoL were recorded: age, gender, physical status, having a partner at admission, living in an institution, prefracture level of mobility, anemia, type of fracture and treatment, delirium during hospital stay and length of stay.

RESULTS

HRQoL declined between baseline and 3 months, and recovered between three and 12 months. PCS HRQoL did not recover to baseline values, MCS HRQoL did. Age younger than 80 years, ASA classification I and II, higher prefracture level of mobility, intracapsular fracture and treatment with osteosynthesis (compared to arthroplasty) were associated with greater initial decline in PCS HRQoL, none of the recorded factors were significant for decline in MCS HRQoL.

CONCLUSIONS

Both PCS and MCS HRQoL declined after a hip fracture and PCS did not recover to baseline values. Healthier patients may need extra care to prevent them from having a steep decline in postoperative PCS HRQoL and arthroplasty should be considered with low threshold.

Quality of life after hip fracture in the elderly: A systematic literature review

BACKGROUND

With an increasing ageing population, hip fractures have become a major public health issue in the elderly. It is important to examine the health status (HS) and health-related quality of life (HRQOL) of the elderly faced with the epidemic of hip fractures.

OBJECTIVE

To provide an overview of reported HS and HRQOL in elderly patients with a hip fracture.

DESIGN

A systematic literature search was performed in Embase, Medline, Web of Science, Scopus, CINAHL, Cochrane, PsycINFO, Pubmed, and Google Scholar in July 2014. Studies which reported the HS or HRQOL based on standardised questionnaires in patients older than 65 years with a hip fracture were considered eligible for inclusion.

RESULTS

After inspecting the 2725 potentially eligible studies, 49 fulfilled the inclusion criteria. All included studies were randomised controlled trials or prospective cohort studies. The methodological quality of the studies was moderate. Patients' functioning on the physical, social, and emotional domains were affected after a hip fracture. The HS and HRQOL of the majority of patients recovered in the first 6 months after fracture. However, their HS did not return to prefracture level. Mental state, prefracture functioning on physical and psychosocial domains, comorbidity, female gender, nutritional status, postoperative pain, length of hospital stay, and complications were factors associated with HS or HRQOL. Treatment with total hip arthroplasty or hemi-arthroplasty provided better HS than treatment with internal fixation with displaced femoral neck fractures. Supportive psychotherapy in "low-functioning" patients, (home) rehabilitation programmes and nutritional supplementation appeared to have beneficial effects on HS.

CONCLUSIONS

Optimizing nutrition intake, (home) rehabilitation programmes, and the possibility for psychological counselling in patients with difficulties in the psychosocial dimensions would be recommended after hip fracture surgery. Besides HS questionnaires like EQ-5D and SF-36, adequate measurements like the WHOQOL-Bref or ICECAP-O are warranted in future studies regarding hip fracture surgery and postoperative treatment options.

Type of surgery is associated with pain and walking difficulties among older people with previous hip fracture

AIM

The aim was to assess the level of lower body pain among people with previous femoral neck fracture, and whether the type of surgery was associated with pain and physical function a mean of 2 years after surgery.

METHODS

The study included 115 community-dwelling older adults aged 60 years and older with previous femoral neck fracture, and 31 reference subjects without previous lower limb injuries. A total of 30 patients had internal fixation surgery, 70 had hemiarthroplasty and 15 had total hip replacement. All patients had surgery in the same hospital and received typical inpatient rehabilitation. From 1.6 months to 7.5 years after the fracture, the patients underwent examination including clinical evaluation, measurements of pain in the lower body (visual analog scale), physical function (maximal walking speed, Timed Up & Go, Berg Balance Scale) and self-reported walking difficulties.

RESULTS

Hip fracture patients reported more pain (81 ± 88 mm) compared with the reference group (25 ± 39 mm, P = 0.004). Patients with internal fixation reported significantly more pain than the other study groups. Significantly more patients with internal fixation (53%) reported walking difficulties compared with patients who had hemiarthroplasty (29%, P = 0.028) or total hip replacement (13%, P = 0.018). No significant difference was observed in performance-based physical function between the fracture groups, but participants in the reference group had better physical function than any of the fracture groups.

CONCLUSIONS

Hip fracture patients treated with internal fixation experienced more pain and walking difficulties than the hemiarthroplasty and total hip replacement groups. Different types of surgical fixation might require different rehabilitation and pain management strategies after hip fracture. Geriatr Gerontol Int 2015; ●●: ●●-●●.

Radiographic fracture features predicting failure of internal fixation of displaced femoral neck fractures

INTRODUCTION

Fixation-related complications of displaced femoral neck fractures treated by internal fixation are accompanied by high mortality and morbidity. The aim of this study is to investigate the pre- and postoperative radiographic fracture characteristics in relation to patient age and the occurrence of reoperation caused by fixation failure.

METHODS

The preoperative radiographs of all patients presenting with a proximal femur fracture between January 2004 and December 2012 were retrospectively assessed for fracture type and dislocation (AP and lateral view). Patients with a displaced femoral neck fracture treated by closed reduction and internal fixation were included. The postoperative radiographs were assessed on adequate fracture reduction and correct position of the implant. Patient characteristics and outcome in terms of occurrence of fixation failure (implant breakout, non-union) and reoperation rate were recorded.

RESULTS

Hundred and-forty-nine patients were admitted with a displaced femoral neck fracture and treated by internal fixation. Fixation failure was seen in 34 (23%) patients; 9 patients suffered from osteonecrosis. In total, 37 (25%) patients underwent reoperation caused by fixation-related complications. Taking the different age categories into account, 44% of the patients >75 years suffered fixation failure compared with 17% of the patients <65 years. Postoperative incorrect reduction, with persisting dorsoventral dislocation and/or lack of medial support resulted in reoperation in 37% of the patients, compared to 19% reoperations in patients with adequate reduction.

CONCLUSION

The results of this study show that patient age and fracture reduction are important predictors for reoperation. In the preoperative treatment plan, patient age should be taken into account and surgeons should strive for anatomical reduction. Patients over 75 should always undergo arthroplasty. In patients aged 65-75, conversion to arthroplasty should be strongly considered if anatomical reduction is impossible.

The Result of In Situ Pinning for Valgus Impacted Femoral Neck Fractures of Patients over 70 Years Old

Purpose

We aimed to evaluate the outcome of fixation with cannulated screws for valgus impacted femoral neck fractures in patients over 70 years of age.

Materials and Methods

We reviewed the outcome in 33 patients older than 70 years with valgus impacted femoral neck fractures who were treated with cannulated screws fixation from May 2007 to December 2010. These patients were followed for at least a year. We assessed the fixation failure rate, body mass index (BMI), bone mineral density (BMD) of proximal femur, distance between screw tip and joint, number of screws and time from fracture to operation.

Results

We identified six patients (18.2%) with failure. Two patients with subtrochanteric fractures through the screw insertion site and another patient with osteonecrosis were excluded from the fixation failure group. No difference was found in age, BMI, BMD of proximal femur, distance between screw tip and joint, number of screws and time from fracture to operation between failure and non-failure groups.

Conclusion

The failure rate of cannualted screw fixation for valgus impacted femoral neck fractures in the elderly patients was not low. Risk of failure should be considered in the management of these patients and accurate assessment for fracture type should be performed using computed tomogram and clinical evaluation.

[More patients in a shorter inpatient stay with better outcome in treatment of femoral neck fracture: external quality assurance in Westfalia-Lippe on 50,354 patients]

BACKGROUND

We show a comparison between two patient groups of the inpatient population suffering from femoral neck fractures registered in the external quality assurance between 1993 and 1997 and between 2005 and 2009.

RESULTS

The comparison between two patient groups showed the following developments: an increase in patient numbers per year from 4,229 to 5,842 where the average age remained constant but the proportion of elderly patients over 70 years old increased; the period of hospitalization was clearly shorter (from 27 days to 18 days); an increase in comorbidities (according to the ASA classification) with simultaneous decrease of the complication rate (from 11.1% to 7.6%). The inhospital mortality remained constant at 5.3%. At the same time the number of hospitals which treat patients with femoral neck fractures decreased from 166 to 150. Concurrently the number of patients per hospital and year increased from 23.6 to 41.3 cases.

CONCLUSION

The technique of operative treatment changed and while during the 1990s many patients with femoral neck fractures were treated by implanting a total endoprosthesis, in the 2000s treatment was dominated by the hemi prosthesis. During the two periods of study use of the osteosynthesis technique decreased. In conclusion, the study showed an obvious compression of performance in trauma surgery but despite everything there was a clear improvement of treatment quality with respect to complication rates.

Role of fracture and repair type on pain and opioid use after hip fracture in the elderly

BACKGROUND AND PURPOSE

Pain after hip fracture repair is related to worse functional outcomes and higher fracture care costs than that for patients with no or less pain. However, to our knowledge, few studies have examined the roles of hip fracture type or surgical procedure as factors influencing postoperative pain or opioid analgesic requirements. Our goal was to determine whether the type of hip fracture or hip fracture repair affects postoperative pain or opioid analgesic requirements in the elderly patient.

METHODS

We conducted a retrospective review of 231 patients ≥65 years old admitted to a hip fracture center for surgical repair. Fracture patterns were classified into femoral neck (FN) versus intertrochanteric (IT), stable versus unstable, and type of surgical repair. Demographic and intraoperative variables, postoperative pain scores, and opioid analgesic use data were collected and analyzed according to the type of hip fracture and type of surgical repair.

RESULTS

There were no differences in postoperative pain when comparing FN versus IT fractures, stable versus unstable fractures, or type of surgical repair. Patients with FN fractures had higher analgesic requirements on postoperative days 1, 2, and 3. There was no difference in postoperative analgesic requirements among patients with stable versus unstable fractures or type of surgical repair. Otherwise, there were no differences in postoperative pain or opioid analgesic use based on the surgical repair or fracture type. Overall, patients with hip fracture experienced low levels of pain.

What determines health-related quality of life in hip fracture patients at the end of acute care?--a prospective observational study

Hip fractures are associated with reduced health-related quality of life (HrQoL). We found pre-existing need of care or limited function, cognitive impairment, and depression to be independent factors associated with lower HrQoL during the postsurgical period. In contrast, joint replacement was associated with better HrQoL compared to internal fixation. Patients' treatment should be focused on functional recovery and treatment of depression.

INTRODUCTION

The aim of the study was to identify independent factors that were correlated with health-related quality of life (HrQoL) after hip fracture.

METHODS

A total of 402 patients with a mean age of 81 years suffering from a hip fracture were included in this prospective, observational cohort study. HrQoL (determined by the EuroQol instrument) was measured at admission and at discharge from an acute care hospital. Independent factors correlated with HrQoL at discharge and changes from pre-fracture to discharge were determined using multivariate analyses. The influence of antidepressants was evaluated by an ANOVA with repeated measurements.

RESULTS

Need of care prior to fracture was the most important determinant of EQ-5D index at discharge (ß = -0.359, p = 0.003). Additionally, low Mini Mental Status Examination (MMSE) was associated with a lower EQ-5D index at discharge (MMSE 0-9: ß = -0.238, p <0.001; MMSE 10-19: ß = -0.294, p <0.001) and a greater decrease in EQ-5D during hospitalisation (MMSE 10-19: ß = 0.281, p <0.001), while joint replacement (compared to internal fixation) was associated with a higher EQ-5D index (ß = 0.188, p = 0.002) and a lower decrease in the index (ß = -0.216, p = 0.003). EQ VAS values at discharge were correlated with pre-fracture Barthel Index (ß = 0.253, p <0.001) and Geriatric Depression Scale scores (ß = -0.135, p = 0.026). Depressive patients on antidepressants demonstrated less of a decrease in the EQ-5D index compared to patients not receiving medication (F = 2.907, p = 0.090).

CONCLUSIONS

Acute care of hip fracture patients should be focused on functional recovery and treatment of depression. When the preferred surgical strategy is unclear, joint replacement should be considered.

An 8-year follow-up study of 221 consecutive hip fracture patients in Finland: analysis of reoperations and their direct medical costs

BACKGROUND

Some hip fracture patients need one or more reoperations because of complications following initial operative treatment.

AIMS

The aim of this study was to identify all further surgical interventions in a cohort of patients with hip fractures over a period of 8 years after index fracture. Immediate direct costs of these reoperations were also calculated.

MATERIAL AND METHODS

This retrospective study investigated 221 consecutive patients with hip fractures operated on at two different hospitals in southeastern Finland. The study period in hospital A was from 1 February 2003 to 31 January 2004, and in hospital B from 1 February 2003 to 30 April 2004. About 50% were femoral neck fractures, 41% trochanteric fractures, and 9% subtrochanteric fractures. Patients' medical records were checked from the hospital records and confirmed manually. Short- and long-term complications were recorded. Survival analysis was performed using a life-table method. The actual costs for reoperations and other further procedures for each patient were calculated using diagnosis-related groups-based costs for both hospitals in 2012.

RESULTS

A total of 20 patients (9%) needed reoperations. Overall, 10 patients (8.9%) with a femoral neck fracture (n = 112), 8 patients (8.7%) with trochanteric fracture (n = 92), and 2 patients (10.5%) with subtrochanteric fracture (n = 19) were reoperated on. The median interval between the primary operation of the acute hip fracture (n = 20) and the first reoperation was about 300 days (range: 2 weeks to 82 months). Among the women reoperated on, the excess mortality was lower than among those undergoing a single operation. The median costs of treatment per patient with one or more reoperations were €13,422 in hospital A (range: €1616-€61,755), €11,076 in hospital B (range: €1540-€17,866), and €12,850 in the total study group (p = 0.43). In the case of infections (3 patients), the mean costs per patient were €28,751 (range: €11,076-€61,755).

CONCLUSIONS

Almost 10% of hip fracture patients required reoperations, and these reoperations caused significant direct costs to health care. However, direct costs account for only approximately 25% of the first year's total costs. These costs should be taken into account when evaluating the economics of hip fractures and the burden of health care.

Patient-reported outcome after displaced femoral neck fracture: a national survey of 4467 patients

BACKGROUND

Arthroplasty appears to be superior to internal fixation, with regard to complication rates, as a treatment for displaced femoral neck fractures. Less is known about the result as perceived by the patient. The aims of this prospective observational study were (1) to determine whether patient-reported outcomes after a displaced femoral neck fracture can be evaluated on a nationwide basis by means of a mailed survey, and (2) to evaluate differences among treatment methods with respect to patient-reported pain, health-related quality of life, and satisfaction with the surgical result.

METHODS

Through collaboration between the Swedish Hip Arthroplasty Register and the Swedish National Hip Fracture Register, 5902 patients (median age, eighty-four years; range, eighteen to 103 years) treated with internal fixation, total hip arthroplasty, or hemiarthroplasty for a displaced femoral neck fracture were identified. A composite questionnaire, including the EQ-5D and visual analog scales for pain and for satisfaction with the surgical result, was mailed to the 4467 patients who remained alive (median follow-up, fourteen months; range, seven to twenty-two months).

RESULTS

The total response rate was 79% (n = 3513); 72% to 75% of the patients completed each of the questionnaire sections. Both patients below and patients above seventy years of age treated with total hip arthroplasty reported less pain and were more satisfied compared with those treated with internal fixation or hemiarthroplasty (although the differences between total hip arthroplasty and hemiarthroplasty in patients below seventy years of age did not reach significance).

CONCLUSIONS

A mailed patient-reported outcomes questionnaire is a feasible method for national follow-up of hip fractures, with an acceptable response rate. The study also suggests that total hip arthroplasty as a treatment for femoral neck fracture is associated with less pain and greater satisfaction at short-term follow-up compared with internal fixation and hemiarthroplasty, both in patients younger and older than seventy years.

Outcome of an uncemented hydroxyapatite coated hemiarthroplasty for displaced femoral neck fractures: a clinical and radiographic 2-year follow-up study

BACKGROUND AND PURPOSE

Hemiarthroplasty is the preferred treatment for displaced femoral neck fractures (DFNF) in elderly patients. The use of uncemented stems remains controversial and issues regarding inferior fixation in osteoporotic bone, implant-related pain and decreased mobility have discouraged their use. There is limited evidence for the use of modern uncemented femoral stems in the treatment of DFNF, and we wished to investigate the clinical and radiographic performance of an uncemented hydroxyapatite coated hemiarthroplasty at 2-year follow-up.

PATIENTS AND METHODS

We included 97 consecutive patients who had an uncemented, hydroxyapatite coated hemiarthroplasty (Corail, Depuy) inserted during a 1-year period. Due to unwillingness or cognitive impairment (n = 6) and death before follow-up (n = 44), a total of 47 patients (39 females) with a mean age of 81 years were available.

RESULTS

At two year follow-up 38 of 47 patients lived in their own homes and the median New Mobility Score was 6 (range: 2-9). The median Visual Analogue Scale pain score was 0 (range: 0-5) at rest and 0 (range: 0-8) when walking. Patient satisfaction was a score of 9 (range: 2-10) on the VAS. Anterior or lateral thigh pain or groin pain was reported by 15 patients. The EQ-5D index score at follow-up was 0.72 (range: 0.16-1.00) and the EQ-5D Visual Analogue Score was 70 (range: 15-100). There were no signs of implant loosening in any of the 37 hips undergoing radiographic evaluation at follow-up.

CONCLUSION

The results suggest that an uncemented hydroxyapatite coated hemiarthroplasty can be used to treat displaced intracupsular femoral neck fractures with good clinical and radiographic outcomes at short term follow-up.

Decreasing mortality after femoral neck fracture treated with bipolar hemiarthroplasty during the last twenty years

PURPOSE

The aim of our study was to investigate trends over time in the mortality of elderly patients after femoral neck fractures treated with bipolar hemiarthroplasty.

METHODS

Altogether 487 cases of femoral neck fracture treated with bipolar hemiarthroplasty were observed during a 20-year period. Mortality rates were calculated for five years postoperatively. To account for the age distribution of the study population standardised mortality ratios (SMR) with respect to the age-specific mortality of the German population were determined and compared. Additional changes of the SMRs over time and the influence of the time delay before surgery on long-term mortality were evaluated.

RESULTS

Femoral neck fractures treated with bipolar hemiendoprosthesis have a significant impact on mortality. Postoperative mortality is increased in patients of all age groups, but the effect diminishes in higher age groups. The influence on mortality was significantly greater for men than for women. The SMR has decreased from 3.52 before 1995 to 1.2 after 2006. Since 2006 there is no longer an increase in mortality after surgical treatment of a femoral neck fracture compared to general German population of the same age.

CONCLUSION

Femoral neck fractures treated with bipolar hemiendoprosthesis result in a significantly increased mortality, however in our population this impact has significantly decreased over time. The effect on mortality is less in women and higher age groups than in men and younger patients. No influence of the time between accident and surgery on mortality could be detected.

Dual mobility cups hip arthroplasty as a treatment for displaced fracture of the femoral neck in the elderly. A prospective, systematic, multicenter study with specific focus on postoperative dislocation

INTRODUCTION

Displaced fractures of the femoral neck in the elderly are best treated with arthroplasty. The type of arthroplasty to be used, either hemi- or total hip arthroplasty, remains controversial as total hip replacements potentially have a higher rate of dislocation.

HYPOTHESIS

Dual mobility cups have a low dislocation rate when used to manage acute fractures of the femoral neck.

PATIENTS AND METHODS

In a multicenter prospective study conducted in France over an inclusion time of 3 months, all displaced fractures of the femoral neck treated with arthroplasty were operated on with insertion of a dual mobility cup. Patients had clinical and radiological assessment at 3, 6, and 9 months postoperative.

RESULTS

Two hundred and fourteen hips in 214 patients with a mean age of 83 years (range, 70-103 years) were included. None of the patients was lost to follow-up. The mortality rate after 9 months was 19%. Two patients (1%) had early postoperative infection successfully treated with lavage and antibiotics. Three patients (1.4%), operated through a posterior approach, presented one postoperative dislocation, all of which were posterior. Reduction was performed through closed external manipulation under general anesthesia. There was no recurrence of dislocation.

DISCUSSION

This low rate of dislocation after acute total hip replacement using dual mobility design cups favorably compares with hemiarthroplasties. Dual mobility cups might therefore be considered a valuable option to prevent postoperative dislocation when treating displaced intracapsular fractures of the proximal femur in elderly patients if a total hip replacement is recommended. Further study is needed before extending the indications for total hip arthroplasty following a fracture of the femoral neck, to assess the potential cost and complications of a longer procedure with its potential acetabular complication, and weigh them against the potential benefits.

Recovery after hip fractures: influence of bipolar hemiarthroplasty on physical disability and social dependency in the elderly

Surgical treatment of femoral neck fractures is associated with a significant impact on quality of life. The aim of this study was to determine the long-term influence of displaced femoral neck fractures treated by bipolar hemiarthroplasty on the activities of daily living, quality of life and social dependency. We studied 487 geriatric patients treated in the years 1989 to 2003. At the beginning of follow-up in 2004, 166 patients were alive and evaluation was carried out on 145 patients (87.3%) at 91.3 (14 - 244) months postoperatively by a standardized questionnaire. All enrolled patients had been treated with cemented bipolar hemiarthroplasty for a displaced femoral neck fracture. Patients were evaluated concerning their average pre- and postoperative ability to walk, the need for assisting devices, type of residency and the SF-12® Score. Femoral neck fracture and hemiarthroplasty had a significant influence on all recorded aspects of quality of life. Even though almost two thirds of the patients needed assisting devices to walk after surgery, about two thirds returned to their original type of accommodation and the majority reached their original degree of mobility. Compared to a normal population no significant impact was observed on the quality of life measured by the SF-12® score. We consider bipolar hemiarthroplasty an effective treatment option for displaced femoral neck fractures in geriatric patients. Most patients returned to their original type of accommodation and level of mobility, even though the majority required a number of assisting devices to do so.

Fixation of the fully hydroxyapatite-coated Corail stem implanted due to femoral neck fracture: 38 patients followed for 2 years with RSA and DEXA

BACKGROUND

Today, dislocated femoral neck fractures are commonly treated with a cemented hip arthroplasty. However, cementing of the femoral component may lead to adverse effects and even death. Uncemented stems may lower these risks and hydroxyapatite (HA) coating may enhance integration, but prosthetic stability and clinical outcome in patients with osteoporotic bone have not been fully explored. We therefore studied fixation and clinical outcome in patients who had had a femoral neck fracture and who had received a fully HA-coated stem prosthesis.

PATIENTS AND METHODS

50 patients with a dislocated femoral neck fracture were operated with the fully HA-coated Corail total or hemiarthroplasty. 38 patients, mean age 81 (70-96) years, were followed for 24 months with conventional radiographs, RSA, DEXA, and for clinical outcome.

RESULTS

31 of the 38 implants moved statistically significantly up to 3 months, mainly distally, mean 2.7 mm (max. 20 mm (SD 4.3)), and rotated into retroversion mean 3.3º (-1.8 to 17) (SD 4.3) and then appeared to stabilize. Distal stem migration was more pronounced if the stem was deemed to be too small. There was no correlation between BMD and stem migration. The migration did not result in any clinically adverse effects.

INTERPRETATION

The fully hydroxyapatite-coated Corail stem migrates during the first 3 months, but clinical outcome appears to be good, without any adverse events.

Does the choice of approach for hip hemiarthroplasty in geriatric patients significantly influence early postoperative outcomes? A randomized-controlled trial comparing the modified Smith-Petersen and Hardinge approaches

BACKGROUND

Minimally invasive surgical approaches for total hip replacement, such as the modified Smith-Petersen approach, have been reported to be advantageous over alternative techniques because of reduced soft tissue damage and improved immediate postoperative rehabilitation. This study compares the advantages of the Smith-Petersen approach against the lateral Hardinge approach for femoral neck fractures in geriatric patients.

METHODS

In a randomized-controlled trial, 48 patients were treated by a hemiarthroplasty of the hip using either a modified Smith-Petersen or a Hardinge approach. Age, American Society of Anesthesiologists score, body mass index, blood loss, pain, and postoperative mobilization were compared between groups to detect statistically significant differences. The same outcome measures were analyzed for significant differences between patients with or without complications in each group.

RESULTS

The Smith-Petersen approach yielded a statistically significant increase in postoperative pain within the first 4 days and an increase in operation time. Complications were also associated with a significantly higher intraoperative time in the same group. However, 6 months postoperatively, there were no significant differences in the Harris Hip score between groups.

CONCLUSIONS

Despite early postoperative differences, postoperative mobility does not seem to be greatly influenced by the choice of either an anterior modified Smith-Petersen or a lateral Hardinge approach for hip hemiarthroplasty. Operative time was significantly linked to postoperative complications. In this respect, it can be concluded that it is not be the approach itself that determines the early postoperative result, but the routine the individual surgeon has with it.

[Quality assurance using routine data. Is outcome quality now measurable?]

Health service quality in Germany can be shown by the data from the external quality assurance program (BQS) but as these records are limited to the period of in-hospital stay no information about outcome after discharge from hospital can be obtained. Secondary routine administrative data contain information about long-term outcome, such as mortality, subsequent revision and the need for care following surgical treatment due to a hip fracture.Experiences in the use of secondary data dealing with treatment of hip fractures from the BQS are available in our department. In addition we analyzed routine administrative data from the health insurance companies Knappschaft Bahn-See and AOK in a cooperative study with the WidO (scientific institute of the AOK). These routine data clearly show a bias because of poor quality in coding as well as broad interpretation possibilities of some of the ICD-10 codes used.Consequently quality assurance using routine data is less valid than register-based conclusions. Nevertheless medical expertise is necessary to avoid misinterpretation of routine administrative data.

Mobility and functional outcomes after femoral neck fracture surgery in elderly patients: a comparison between hemiarthroplasty and internal fixation

PURPOSE

To find out whether patients with femoral neck fracture treated with hemiarthroplasty differ from those treated with internal fixation regarding functional outcome, walking ability, pain or short-term mortality.

METHOD

Sixty-six patients aged 64 years or more with femoral neck fracture were included in a prospective non-randomised trial with two equal-sized groups recruited consecutively within each group. All patients were treated operatively and encouraged to pursue an active rehabilitation. They were reviewed at admission, before discharge and 3 months after surgery. Assessments included demographic data, length of hospitalisation, post-operative medical complications, activities of daily living, walking ability, pain and mortality.

RESULTS

There were no significant differences between the two groups in terms of age, gender, ability to walk, functional status or at admission. The patients treated with hemiarthroplasty had a longer total hospital stay due to longer waiting time to operation. They started to walk sooner after operation and walked better during hospitalisation. Their walking distance at discharge was longer; their improvement in functional independence, as measured by the Functional Independence Measure, was also higher, but this difference was not statistically significant. Observed mortality in the hemiarthroplasty group was lower.

CONCLUSION

A longer follow-up would be necessary to determine whether the preferable outcomes of hemiarthroplasty persist in the long-term.

Unipolar versus bipolar uncemented hemiarthroplasty for elderly patients with displaced intracapsular femoral neck fractures

PURPOSE

To compare outcomes of unipolar versus bipolar uncemented hemiarthroplasty and determine factors affecting outcomes.

METHODS

433 and 274 elderly patients with displaced intracapsular femoral neck fractures underwent uncemented unipolar hemiarthroplasty and uncemented bipolar hydroxyapatite-coated hemiarthroplasty, respectively. Surgical options were based on the patient's general condition and preinjury mobility status. In the respective groups, the mortality of 377 and 242 patients and the mobility of 270 and 217 patients were reviewed at the 4-month follow-up. Patient age, sex, American Society of Anesthesiologists [ASA] score, mobility, and mortality of the 2 groups were compared.

RESULTS

Patients who underwent unipolar hemiarthroplasty were significantly older, less fit, and less mobile (p<0.001). Patients who underwent bipolar hemiarthroplasty achieved better outcomes for mortality and mobility (p<0.001). Among patients who were able to walk unaided before injury, more of those having bipolar hemiarthroplasty were able to do so at month 4 than those having unipolar hemiarthroplasty (13% vs. 33%, p<0.001). Mortality within 4 months was associated with age, male gender, and ASA score. When patients were stratified according to age groups, mortality within 4 months was lower in patients having bipolar hemiarthroplasty.

CONCLUSION

In elderly patients with femoral neck fractures who were fit and physiologically young, uncemented bipolar hemiarthroplasty seemed to achieve better functional outcome.
