摘要

Background

Increasing life expectancy has led to a rise in hip fractures and an associated increase in hemiarthroplasty procedures aimed at restoring mobility and preventing muscle loss. Despite the extensive literature on failed hemiarthroplasty, limited data address the influence of pre-operative fracture types—intracapsular versus extracapsular—on outcomes, including inpatient mortality. This study investigates the revisions of uncemented bipolar hemiarthroplasties concerning fracture type and identifies risk factors for inpatient mortality.

Methods

This retrospective cohort study included 68 patients (16 males and 52 females) who underwent revision of uncemented bipolar hemiarthroplasties at a single institution between 2017 and 2024. Data on demographics, comorbidities, fracture type, surgical details and outcomes were analysed. Statistical analyses included t tests, chi-square tests and logistic regression, with significance set at p < 0.05.

Results

Of 1,690 hemiarthroplasties performed, 68 required revision (revision rate: 4%). Revisions for extracapsular fractures were associated with a higher prevalence of diabetes mellitus (p = 0.01) and elevated Almelo Hip Fracture Score (AHFS; p = 0.01). The overall inpatient mortality rate was 19%, significantly higher in males (43.75%) than females (11.54%; p = 0.00). Deceased patients demonstrated higher AHFS and American Society of Anaesthesiologists scores but lower Parker Mobility Scores (p = 0.01). Prolonged intensive care unit (ICU) stays were also linked to increased mortality (p = 0.02). Logistic regression identified male sex as an independent predictor of mortality (odds ratio: 9.37; p < 0.05).

Conclusions

Pre-operative fracture type significantly influences revision outcomes in failed hemiarthroplasties. Moreover, extracapsular fractures are linked to diabetes mellitus and higher AHFS, whereas male sex, ICU stay duration and comorbidity scores predict inpatient mortality. These findings highlight the need for tailored perioperative care to mitigate risks.
