Hip Fracture Mortality: Differences Between Intertrochanteric and Femoral Neck Fractures

Abstract

The purpose of this study was to identify the specific risk factors that affect mortality in patients with hip fractures and differentiate mortality-associated factors between intertrochanteric (IT) and femoral neck (FN) fractures. A total of 1538 consecutive patients with hip fractures were treated at the authors' institution between January 2005 and October 2013. Ultimately 858 IT and 479 FN fracture patients were included on the basis of age >60 years with an isolated hip fracture. Mortality rate at 90 days was 12.1% for IT and 9.6% for FN fractures. In both IT and FN fractures, variables associated with mortality risk include increased age, greater days to surgery, male gender, decreased body mass index, and increased American Society of Anesthesiologists score. When evaluated independently, the presence of cardiac arrhythmia and chronic kidney disease was strongly associated with greater mortality risk in FN fracture patients. The presence of chronic kidney disease and hypertension correlated with decreased mortality risk among FN fracture patients. (Journal of Surgical Orthopaedic Advances 27(1):64-71, 2018).
