ABSTRACT
BACKGROUND AND PURPOSE: Hip fracture treatment with (hemi)arthroplasty carries a risk of periprosthetic joint infection (PJI), which may be reduced by using dual antibiotic-loaded bone cement (ALBC). We aimed to compare the rate of all-cause revision, revision for infection, and mortality following single or dual ALBC use in hip fracture arthroplasty.
METHODS: From the Dutch Arthroplasty Register, we identified all cemented hemiarthroplasties (HA) and total hip arthroplasties (THA) performed in the period 2007-2024 for proximal femoral fracture. Crude cumulative incidences of all-cause and infection revision were estimated using competing risk survival analyses with death as competing event. Mortality was estimated using Kaplan-Meier analysis. Cause-specific Cox regression models adjusting for age, year of surgery, history of previous surgeries, and American Society of Anesthesiologists (ASA) classification estimated hazard ratios (HRs).
RESULTS: We analyzed 56,434 hip arthroplasties, of which 1,651 used dual ALBC. 1-year crude cumulative incidences were similar across groups for all-cause revision, infection revision, and mortality. After adjustment, dual ALBC was not associated with a reduced rate of all-cause revision (HR 1.2, 95% confidence interval [CI] 0.9-1.5]) compared with single ALBC. Dual ALBC was associated with a modestly higher revision for infection (HR 1.6, CI 1.0-2.5) and mortality in HA (HR 1.2, CI 1.1-1.2).
CONCLUSION: Dual ALBC was not associated with lower revision rates compared with single ALBC but a modestly higher revision rate was noted for infection and mortality following hip arthroplasty after hip fracture.
