HOPE-Trial: Hemiarthroplasty Compared with Total Hip Arthroplasty for Displaced Femoral Neck Fractures in Octogenarians: A Randomized Controlled Trial.

ABSTRACT:

Background

The choice of primary hemiarthroplasty or total hip arthroplasty in patients ≥80 years of age with a displaced femoral neck fracture has not been adequately studied. As the number of healthy, elderly patients ≥80 years of age is continually increasing, optimizing treatments for improving outcomes and reducing the need for secondary surgery is an important consideration. The aim of the present study was to compare the results of hemiarthroplasty with those of total hip arthroplasty in patients ≥80 years of age.

Methods

This prospective, randomized, single-blinded trial included 120 patients with a mean age of 86 years (range, 80 to 94 years) who had sustained an acute displaced femoral neck fracture <36 hours previously. The patients were randomized to treatment with hemiarthroplasty (n = 60) or total hip arthroplasty (n = 60). The primary end points were hip function and health-related quality of life at 2 years. Secondary end points included hip-related complications and reoperations, mortality, pain in the involved hip, activities of daily living, surgical time, blood loss, and general complications. The patients were reviewed at 3 months and 1 and 2 years.

Results

We found no differences between the groups in terms of hip function, health-related quality of life, hip-related complications and reoperations, activities of daily living, or pain in the involved hip. Hip function, activities of daily living, and pain in the involved hip deteriorated in both groups compared with pre-fracture values. The ability to regain previous walking function was similar in both groups.

Conclusions

We found no difference in outcomes after treatment with either hemiarthroplasty or total hip arthroplasty in active octogenarians and nonagenarians with a displaced femoral neck fracture up to 2 years after surgery. Hemiarthroplasty is a suitable procedure in the short term for this group of patients.

Project description:BackgroundRandomized controlled trials (RCTs) are the most reliable way of evaluating the effect of new treatments by comparing them with previously accepted treatment regimens. The results obtained from an RCT are extrapolated from the study environment to the general health care system. The ability to do so is called external validity. We sought to evaluate the external validity of an RCT comparing the results of total hip arthroplasty with those of hemiarthroplasty for the treatment of displaced femoral neck fractures in patients ≥80 years of age.MethodsThis prospective, single-center cohort study included 183 patients ≥80 years of age who had a displaced femoral neck fracture. All patients were screened according to the inclusion and exclusion criteria for an RCT comparing total hip arthroplasty and hemiarthroplasty. The population for this study consisted of patients who gave their informed consent and were randomized into the RCT (consenting group, 120 patients) as well as those who declined to give their consent to participate (non-consenting group, 63 patients). The outcome measurements were mortality, complications, and patient-reported outcome measures. Follow-up was carried out postoperatively with use of a mailed survey that included patient-reported outcome questionnaires.ResultsWe found a statistically significant and clinically relevant difference between the groups, with the non-consenting group having a higher risk of death compared with the consenting group. (hazard ratio, 4.6; 95% confidence interval, 1.9 to 11.1). No differences were found between the groups in terms of patient-reported outcome measures or surgical complications.ConclusionsThis cohort study indicates a higher mortality rate but comparable hip function and quality of life among eligible non-consenters as compared with eligible consenters when evaluating the external validity of an RCT in patients ≥80 years of age with femoral neck fracture.Level of evidenceTherapeutic Level II.

Project description:BackgroundDisplaced intracapsular hip fractures are typically treated with hemiarthroplasty (HA) or total hip arthroplasty (THA). A number of professional bodies recommend considering THA for patients that were independently mobile and cognitively intact before injury. The aim of this study was to compare the outcomes between HA and THA for independently mobile older adults with hip fractures.MethodsA systematic review and meta-analysis of RCTs was undertaken alongside analysis of a propensity score matched national cohort of older adults (aged > 60) with hip fractures. Participants were identified for the propensity score matched cohort from the National Hip Fracture Database (NHFD), which was linked to Hospital Episode Statistics (HES) and civil death registration data. The primary outcomes were 12-month dislocation, revision, and mortality. The secondary outcomes were length of stay, discharge home, unplanned re-admission, functional outcomes, and health-related quality of life.ResultsFive RCTs reported higher THA dislocation but this was not statistically significant (THA risk ratio [RR] 2.77, 95% CI 0.81 to 9.48). However, THA dislocation was significantly higher in the national observational dataset (sub-distribution hazard ratio [SHR] 1.73, 95% CI 1.24 to 2.41). Meta-analysis of data from four RCTs did not identify a significant difference in terms of revision (RR 1.52, 95% CI 0.56 to 4.14). However, THA revision was significantly lower in the national dataset (SHR 0.66, 95% CI 0.48 to 0.90). Meta-analysis of data from 5 RCTs suggested higher mortality amongst patients undergoing HA (RR 0.63, 95% CI 0.38 to 1.04), which was also observed within the national registry dataset (hazard ratio 0.45, 95% CI 0.37 to 0.54).ConclusionsNational clinical registries can provide important context when interpreting RCT data, which may alone be inadequate for comparing the safety profile of surgical interventions. These data suggest that THA is at significantly higher risk of dislocation but lower risk of revision within 12 months. The finding from both RCT and clinical registry data that THA is associated with lower 12-month mortality amongst the fittest patients with hip fractures requires urgent further study to determine whether or not this can be replicated in other balanced populations.
