Khoshbin A, Hoit G, Henry PDG, et al. - The present study was performed to assess the risk of a secondary total hip arthroplasty (THA) in older patients (> 60 years old) with prior acetabular fractures (AF) open reduction internal fixation (ORIF) compared to younger patients (< 60 years old) with an AF ORIF on a large population level. Researchers distinguished and enrolled all adult patients with an AF ORIF and a minimum of two years follow-up using administrative healthcare data from 1996-2010 inclusive of all 202 hospitals in Ontario, Canada. They analyzed the risk of THA using a Cox proportional hazards model adjusting for patient risk factors. In this study, a sum of 1,725 individuals had an AF ORIF; 1,452 (84.2%, mean age of 38.3 ± 12.1 years) aged < 60 years (“younger”) and 273 (15.8%, mean age of 69.9 ± 7.8 years) >60 years (“older”). Compared to younger patients with an AF ORIF, older patients with an AF ORIF are at a significantly higher risk for a secondary THA.
