Association between Hemiarthroplasty vs Total Hip Arthroplasty and Major Surgical Complications among Patients with Femoral Neck Fracture

Discharge to a Skilled Nursing Facility After Hip Fracture Results in Higher Rates of Periprosthetic Joint Infection

BACKGROUND

Femoral neck fractures (FNFs) in elderly patients are associated with major morbidity and mortality. The influence of postoperative discharge location on recovery and outcomes after arthroplasty for hip fractures is not well understood.

METHODS

A multisite retrospective cohort from 9 academic centers identified patients who had FNF treated with hemiarthroplasty or total hip arthroplasty between 2010 and 2019. Patients who had diagnoses of dementia, stroke, age > 80 years, or high energy fracture were excluded. Discharge location was identified, including home-based health services (HHS), inpatient rehabilitation (IPR), or a skilled nursing facility (SNF). Rates of reoperation, periprosthetic joint infection (PJI), and mortality were compared between cohorts. Multivariate logistic regressions were performed, adjusting for age, American Society of Anesthesiologists (ASA) score, body mass index, sex, and tobacco use. Statistical significance was defined as P < .05.

RESULTS

A total of 672 patients (315 HHS, 144 IPR, and 213 SNF) were included in this study. The average follow-up was 30 months. The SNF cohort was significantly older (P < .0001) with higher ASA scores (P < .0001) than the HHS cohort. In a logistic regression model adjusting for age, ASA score, and body mass index, the SNF cohort had higher mortality rates than the HHS cohort (P = .0296) and were more likely to have PJI within 90 days (odds ratio = 4.55, 95% confidence interval = 1.40, 4.74) and within 1 year (odds ratio = 3.08, 95% confidence interval = 1.08, 8.78). Time to PJI was significantly shorter in the SNF cohort (SNF 38 versus HHS 231 days, P = .0155). No differences were seen in dislocation or reoperation rates between the SNF and HHS cohorts. No differences were seen in complication rates between the IPR and HHS cohorts.

CONCLUSIONS

Discharge to a SNF after arthroplasty for FNF is associated with increased mortality and higher rates of PJI. Hip fracture care pathways that uniformly discharge patients to SNFs may need to be re-evaluated, and surgeons should consider discharge to home with HHS when possible.

Association between additional weekend rehabilitation and functional outcomes in patients with hip fractures: does age affect the effectiveness of weekend rehabilitation?

PURPOSE

Rehabilitation after hip fracture surgery is crucial for improving physical function. Additional rehabilitation over the weekend or after working hours is reportedly associated with improved physical function; however, this may not apply to an aging population, including patients aged > 90 years. This study aimed to investigate the association between additional weekend rehabilitation and functional outcomes in different age groups.

METHODS

This study analyzed a cohort of patients aged ≥ 60 years who had hip fractures and were operated on from 2010 to 2018. Data were extracted from a nationwide multicentre database. Functional outcomes at discharge were compared between patients who underwent rehabilitation on weekdays only and those who underwent rehabilitation on both weekdays and weekends. The patient groups were selected using propensity score matching analysis. Furthermore, a subgroup-analysis was conducted on patients in their 60 s, 70 s, 80 s, and 90 s.

RESULTS

A total of 390,713 patients underwent surgery during the study period. After matching, each group comprised 129,583 pairs of patients. Patients who underwent weekend rehabilitation exhibited improved physical function in transferring, walking, and stair climbing at discharge, as compared with patients who did not (odds ratio [95% confidence interval]: 1.17 [1.15-1.19], 1.17 [1.15-1.2], and 1.06 [1.03-1.08], respectively). In subgroup analysis, except for stair climbing, the positive association between weekend rehabilitation and patient function was observed across all age groups.

CONCLUSION

Weekend rehabilitation was significantly associated with improved physical function. Given the limited healthcare resources, high-demand activities such as stair climbing may be reserved for younger age groups to optimise rehabilitation therapy.

Unipolar Hip Hemiarthroplasty in Geriatric Patients: A Prospective Study and Analysis of Clinical and Radiological Outcomes

Introduction

Femoral neck fractures (FNF) in the geriatric population are commonly treated with hip replacement procedures, such as total hip arthroplasty, unipolar hip hemiarthroplasty (UHA), and bipolar hip hemiarthroplasty (BHA). The optimal treatment remains controversial, considering outcomes and cost-effectiveness, with UHA often being cheaper. This prospective observational study aims to evaluate UHA's clinical and radiological outcomes, safety, and survivorship compared to existing literature.

Methods

We followed 90 elderly patients who underwent UHA following FNF. We assessed patients using the Parker score before and after surgery, as well as Harris Hip Score (HHS), and Postel-Merle d'Aubigné (PMA) scores postoperatively. All complications, acetabular erosions and heterotopic ossifications (HO), were documented.

Results

One year post-surgery, 26.7% of patients had passed away, mostly due to declining general health status. Systemic complications occurred in 14.4% of cases, with a 1.1% rate of deep surgical site infections. A single dislocation resulted from excessive stem anteversion. UHA implant survival rate was 97.8% after 4 years. The Parker score remained stable, and HHS at 6 and 12 months was 71.5 ± 12.9 and 70.9 ± 11.8, respectively, while PMA score was 14.3 ± 2.4 and 14.5 ± 2.1, respectively. Five hips showed Baker I acetabular wear. HO were noted as Brooker I in 12 patients, II in 4 patients, and IV in 1 patient.

Discussion

UHA exhibited comparable systemic complication rates, implant survivorship, and dislocation rates to those in the literature for both UHA and BHA. The deep surgical site infection rate was lower than reported for BHA. Patients' functional and mental abilities did not decline based on clinical scores. Acetabular wear in UHA was similar to its bipolar counterpart, while HO were only minor findings with no clinical implications.

Conclusion

In elderly patients, UHA demonstrated clinical and radiological outcomes similar to BHA in existing literature. UHA may represent a cost-effective alternative for patients with limited life expectancy.

Displaced Geriatric Femoral Neck Fractures: A Retrospective Comparison of Total Hip Arthroplasties Versus Hemiarthroplasty

Introduction

Controversary exists around the best surgical management for traumatic geriatric displaced femoral neck fractures. The study objective was to compare outcomes among those managed with a total hip arthroplasty (THA) to those managed with a hemiarthroplasty (HA).

Methods

This retrospective matched cohort study included geriatric hip fractures (≥65 y/o) admitted 7/1/16-3/31/20. Patients were matched on having an advanced directive, pre-existing dementia, and age. Outcomes included: time to surgery, length of stay (LOS), blood loss volume, and discharge destination. THAs were compared to HAs; an alpha of <.05 indicated statistical significance.

Results

There were 191 patients: 86% were treated with HA and 14% with THA. Most (40%) were 80-89 years old, 66% were female, and 92% were white. After matching, the groups were well balanced on demographics and baseline characteristics with 27 patients/arm. The median time to surgery was 23 hours for both arms, P = .38. The LOS was significantly longer for those managed with a HA when compared to those managed with a THA, 5.6 vs 4.0 days, P = .001. The median blood loss volume was significantly lower for HAs than for THAs, but the difference was small, 100 vs 120 mL, P = .02. Patients managed with a HA were less likely to be discharged home than those managed with a THA, 22% vs 70%, P = .005.

Conclusions

While patients managed with a THA had significantly more blood loss than those managed with a HA, the difference in blood loss was small and not clinically relevant. Those managed with a THA experienced a significantly shorter LOS and were more likely to be discharged home than patients managed with a HA. Among a healthier, younger geriatric population, THA may lead to shortened LOS and improved discharge destinations when compared to HA for treatment of femoral neck fractures.

Clinical Effectiveness of Total Hip Arthroplasty Compared With Hemiarthroplasty in Adults Undergoing Surgery for Displaced Intracapsular Hip Fracture: A Single-Centre Retrospective Cohort Study

BACKGROUND

The National Institute for Health and Care Excellence (NICE) recommends offering total hip arthroplasty (THA) over hemiarthroplasty (HA) for displaced intracapsular hip fractures, taking the premorbid functionality, present co-morbidities, and functional benefit beyond two years into account. Concerns remain whether the higher surgical burden and incidence of complications in THA would outweigh the potential benefits in the elderly.

METHOD

This retrospective cohort study evaluates the differences in surgical outcomes of THA vs HA in 85 patients with displaced intracapsular fractures, based on the time taken for patients to ambulate to walking frame/crutches and wheelchair post-operatively and the incidence of post-operative complications.

RESULTS

 Patients who received HA were significantly older (p<0.0001, <0.05) and had poorer pre-operative ambulatory function (p=0.032, p<0.05) than those of the THA group. HA patients had a significantly faster recovery to walking frame/crutches (20.2 days) compared to THA patients (47.3 days) (Mann-Whitney U=447.500, n=46, p=0.043, <0.05 two-tailed). While no significant differences were found in deep vein thrombosis (DVT), infected prosthesis, or dislocation incidence, hospital-acquired pneumonia (HAP) was more prevalent in THA patients (p=0.044, <0.05). Time to the walking frame had a significant effect on DVT/PE (p<0.001,

CONCLUSION

HA patients showed favourable outcomes in time to ambulate post-operatively and incidence of HAP among patients with advanced age and those with poorer pre-operative ambulatory function.

Comparative Study of Proximal Femur Bone Tumor Patients Undergoing Hemiarthroplasty versus Total Hip Arthroplasty: A Meta-Analysis

Hemiarthroplasty and total hip arthroplasty are routinely performed procedures. A comparison of these procedures in tumor patients can be performed based on complications and functional outcomes. To weigh the advantages and disadvantages of both procedures, a comparative study is indeed required to decide which procedure is more beneficial for primary bone tumor patients. The outcomes of proximal femur tumor-resected patients were collected from research reports from PubMed, MEDLINE, EMBASE, Cochrane, and Google Scholar until 30 December 2022. Differences between these two operative procedures in primary bone tumors patients were analyzed based on dislocation, infection, local recurrence, MSTS, and HHS. Six articles were included according to the selection criteria with a total of 360 patients. Our results showed that there was a significant difference in our primary outcome as hemiarthroplasty participants encountered less dislocation than those with total hip arthroplasty. Moreover, the secondary outcomes of our study were similar. Proximal femur bone tumors, when resected, tend to produce more complications and decrease functional ability due to extensive tumor extension and soft tissue involvement. The lower dislocation rate in hemiarthroplasty participants emphasizes the importance of preserving the acetabular head in hemiarthroplasty as a key to preventing dislocation.

Risk factors affecting the incidence of postoperative periprosthetic femoral fracture in primary hip arthroplasty patients: a retrospective study

The purpose of this study was to identify the characteristics and risk factors for postoperative periprosthetic femoral fracture (PFF). This was a retrospective cohort study of 108 patients with and 432 control patients without postoperative PFF. Demographic characteristics, surgery-related information (primary hip disease diagnosed, fixation, femoral stem, method of operation, and bone resorption of the proximal femur), and postoperative patient outcomes (hip function, treatment history, and patients' lifestyle behaviors) were recorded and compared between the groups. PFF characteristics, such as the classification, time, and cause, were also documented, and a Cox regression model was built to identify the independent risk factors for postoperative PFF in these patients. Six independent risk factors for postoperative PFF were identified, namely, advanced age (hazard ratio (HR) = 1.026, 95% confidence interval (CI) = 1.007-1.045), femoral neck fracture as the primary disease (HR = 4.536, 95% CI = 2.955-6.961), osteoporosis (HR = 2.043, 95% CI = 1.234-3.383), hemiarthroplasty (or HA, HR = 2.173, 95% CI = 1.327-3.558), bone resorption of the proximal femur (HR = 1.627, 95% CI = 1.090-2.430), and a standard- or long-stem femoral prosthesis (HR = 2.996, 95% CI = 1.480-6.067). The predictive values for a low risk (estimated incidence ≤ 50%), moderate risk (estimated incidence 51%-89%), and high risk (estimated incidence ≥ 90%) of PFF were ≤ 3.0 points, 3.0-10.0 points, and ≥ 10.0 points, respectively. Most patients with postoperative PFF had Vancouver type B fractures. Six independent risk factors for postoperative PFF were identified: advanced age, hip fracture as the primary disease, osteoporosis, HA, bone resorption of the proximal femur, and a long femoral stem.

Mobilisation and physiotherapy intervention following hip fracture: snapshot survey across six countries from the Fragility Fracture Network Physiotherapy Group

PURPOSE

Hip fracture guidelines recommend early mobilisation, multidisciplinary care, physiotherapy and fall prevention interventions. This study documents mobilisation practices and physiotherapy interventions provided post-hip fracture in six countries.

MATERIALS AND METHODS

Physiotherapists from orthopaedic wards in Denmark, Australia, Spain, Brazil, Norway and Ireland provided information regarding mobilisation and physiotherapy for 10 consecutive hip fracture patients (>60 years), between 2014 and 2018.

RESULTS

Physiotherapists (n = 107) entered data on 426 patients. Two-thirds of patients (283, 66%) attempted standing 0-1 days after surgery (range: 0% of patients in Spain to 92% in Norway). Fewer patients (199, 47%) attempted walking on day 0-1 (range: 0% Spain/Brazil to 69% Norway). Physiotherapy to mobilise every weekday was provided to 356 patients (84%, range: 60% Ireland to 100% Spain). On weekends, physiotherapy to mobilise was limited (175, 40%, range: 0% Spain to 81% Brazil) but 298 patients (70%) mobilised with non-physiotherapy staff (range: 0% Spain to 96% Denmark/Ireland). Physiotherapy treatments included mobility, gait training, and range-of-motion exercises. Referral to fall prevention interventions was low (93, 22%, range: 0% Spain to 76% Ireland).

CONCLUSION

Stronger compliance with guideline recommendations on early mobilising, weekend mobilising and referral to fall prevention interventions post hip-fracture is needed in some countries.Implications for rehabilitation This study provides a snapshot of mobilisation and physiotherapy practice for hip fracture patients in six countries. The results suggest a need to improve systems and approaches in some countries to enhance compliance with recommendations specifically relating to: • early attempts at standing and walking post-surgery. • opportunities to mobilise on weekends (with physiotherapist and/or other staff). • broader range of multidisciplinary care e.g., geriatric review, occupational therapy and nutrition advice. • use of standardised tests by physiotherapists post-surgery. • referral to fall prevention interventions.

Functional Status in Older Persons After Hip Fracture Surgery: A Longitudinal Study of Indonesian Patients

BACKGROUND

Hip fractures are one of the most serious injuries affecting older adults. Evidence-based knowledge regarding the functional status of older persons after hip fracture can provide information critical for developing effective continuous-care and rehabilitation programs.

PURPOSE

This study was developed to examine the post-hospital-discharge outcome measures and predictors of functional status in older adults in Indonesia after hip fracture surgery.

METHODS

The functional status of 109 patients discharged from an orthopedic hospital in Indonesia after hip fracture surgery was evaluated in this prospective cohort study. Functional status was evaluated using measures of physical and independent activities of daily living (PADL and IADL, respectively) at 1, 3, and 6 months postdischarge. Predictors of changes in functional status, including age, length of hospital stay, comorbidity, prefracture walking ability, type of surgery, status of depression and nutrition, type of insurance, and residential status (urban vs. rural), were also examined. Data were analyzed using generalized estimating equations.

RESULTS

Significant improvements in PADL were found at 3 and 6 months, and significant improvements in IADL were found at 6 months. Predictors of poor outcomes found in this study included age, a dependent prefracture walking ability, depression, and having public health insurance.

CONCLUSIONS/IMPLICATIONS FOR PRACTICE

The findings of this study support the effectiveness of using presurgery assessments to identify individuals at a higher postdischarge risk of having poor PADL and IADL outcomes. Home nursing or subacute rehabilitation is recommended to improve and maintain functional status in older persons after hip fracture surgery. In addition, interventions and rehabilitation should take into consideration different recovery periods for PADL and IADL after hospital discharge after hip fracture surgery.

SuperPath approach is a recommendable option in frail patients with femoral neck fractures: a case-control study

INTRODUCTION

The treatment of intracapsular femoral neck fractures (FNFs) in the elderly is usually based on hip replacement, both total hip arthroplasty (THA) and hemiarthroplasty (HA). Recently, several tissue-sparing approaches for hip arthroplasty had been described with promising results in terms of hospitalization length, blood loss and dislocation rate. The aim of the present study was to compare the blood loss and the transfusion rate in a cohort of patients with FNF treated using an HA through both the SuperPath (SP) and the traditional posterolateral (PL) approaches.

MATERIALS AND METHODS

We retrospectively collected data from patients affected by FNFs between January 2018 and February 2020. All patients with intracapsular FNF treated with a single HA implant (Profemur L, MicroPort Orthopedics Inc., USA) via PL or SP approaches were included. Exclusion criteria were pathological fractures, polytrauma and preoperatively transfused patients.

RESULTS

Thirty-five patients were included and analysed in the present study. 17 patients were classified in the SP group, and 18 in the PL one. The rate of antithrombotic therapy was higher in the SP group compared with the PL group [10 (58, 82%) vs 4 (22, 2%)]. While the two groups did not differ in terms of preoperative haemoglobin (Hb), 48 h postoperative Hb and Hb reduction, a significative difference was observed in terms of blood transfusion rate (1 SP vs 9 PL, p = 0.0072).

CONCLUSIONS

The SuperPath approach in patients with FNF under antithrombotic therapy assures lower transfusion rate, potentially reducing complication rates and improving patients' outcomes.

Associations between Early Surgery and Postoperative Outcomes in Elderly Patients with Distal Femur Fracture: A Retrospective Cohort Study

Previous literature has provided conflicting results regarding the associations between early surgery and postoperative outcomes in elderly patients with distal femur fractures. Using data from the Japanese Diagnosis Procedure Combination inpatient database from April 2014 to March 2019, we identified elderly patients who underwent surgery for distal femur fracture within two days of hospital admission (early surgery group) or at three or more days after hospital admission (delayed surgery group). Of 9678 eligible patients, 1384 (14.3%) were assigned to the early surgery group. One-to-one propensity score matched analyses showed no significant difference in 30-day mortality between the early and delayed groups (0.5% versus 0.5%; risk difference, 0.0%; 95% confidence interval, −0.7% to 0.7%). Patients in the early surgery group had significantly lower proportions of the composite outcome (death or postoperative complications), shorter hospital stays, and lower total hospitalization costs than patients in the delayed surgery group. Our results showed that early surgery within two days of hospital admission for geriatric distal femur fracture was not associated with a reduction in 30-day mortality but was associated with reductions in postoperative complications and total hospitalization costs.

Prosthesis or osteosynthesis for the treatment of a pathological hip fracture? A nationwide registry-based cohort study

Aims

How endoprosthetic replacement compares to osteosynthesis in the treatment of pathologic hip fractures as far as functional outcome and use of healthcare resources is concerned remains largely unknown. We aimed to investigate this in a nationwide registry.

Methods

We analyzed the functional outcome after surgery for a pathological fracture of the hip in terms of post-operative pain and ambulatory capacity. The preferred surgical method depending on the level of the treating unit was also examined. Furthermore, we documented the length of hospital stay and the patterns of discharge and compared them between these two methods.

Results

Patients operated with an endoprosthesis reported significantly lower pain at follow-up. Both methods (endoprosthetic replacement and osteosynthesis) were equally effective in restoring the ambulatory capacity and demanded a similar length of stay in hospital. Orthopaedic surgeons working in hospitals with dedicated sarcoma teams were more likely to use a prosthesis rather than osteosynthesis, when compared to surgeons working at other university hospitals or emergency hospitals.

Conclusion

Endoprosthetic replacement results in a better functional outcome in terms of post-operative pain without consuming more healthcare resources. Orthopaedic surgeons working in hospitals with sarcoma centers are more likely to use prostheses as compared to surgeons working at hospitals where dedicated musculoskeletal oncology teams are not available.
