Okike K, et al. - This study seeks to correlate the outcomes associated with cemented vs uncemented hemiarthroplasty in a large US integrated health care system. Researchers carried out a retrospective cohort study of 12, 491 individuals aged 60 years and older who had undergone hemiarthroplasty treatment of a hip fracture between 2009 and 2017 at 1 of the 36 hospitals owned by Kaiser Permanente, a large US health maintenance organization. The primary endpoint included aseptic revision, defined as any reoperation performed after the index procedure involving exchange of the existing implant for reasons other than infection. The mortality (in-hospital, postdischarge, and overall), 90-day medical complications, 90-day emergency department visits, and 90-day unplanned readmissions were considered as secondary endpoints. Compared with cemented fixation, uncemented fixation was correlated with a statistically significantly higher risk of aseptic revision among patients with hip fracture treated with hemiarthroplasty in a large US integrated health care system. The data implies that US surgeons should consider cemented fixation in the hemiarthroplasty treatment of displaced femoral neck fractures in the absence of contraindications.
