Increasing life expectancy has led to a rise in hip fractures and an associated increase hemiarthroplasty procedures aimed at restoring mobility preventing muscle loss. Despite the extensive literature on failed hemiarthroplasty, limited data address influence of pre-operative fracture types—intracapsular versus extracapsular—on outcomes, including inpatient mortality. This study investigates revisions uncemented bipolar hemiarthroplasties concerning type identifies risk factors for retrospective cohort included 68 patients (16 males 52 females) who underwent revision single institution between 2017 2024. Data demographics, comorbidities, type, surgical details outcomes were analysed. Statistical analyses t tests, chi-square tests logistic regression, with significance set p < 0.05. Of 1,690 performed, required (revision rate: 4%). Revisions extracapsular higher prevalence diabetes mellitus (p = 0.01) elevated Almelo Hip Fracture Score (AHFS; 0.01). The overall mortality rate was 19%, significantly (43.75%) than females (11.54%; 0.00). Deceased demonstrated AHFS American Society Anaesthesiologists scores but lower Parker Mobility Scores Prolonged intensive care unit (ICU) stays also linked increased 0.02). Logistic regression identified male sex as independent predictor (odds ratio: 9.37; 0.05). Pre-operative influences hemiarthroplasties. Moreover, are AHFS, whereas sex, ICU stay duration comorbidity predict These findings highlight need tailored perioperative mitigate risks. Not applicable.
