Abstract
The outcome of this study was to identify 9-year survivors of intertrochanteric fracture at each stage of chronic kidney disease (CKD) and to investigate the risk factors associated with mortality following surgery with proximal femoral nail anti-rotation (PFNA). 443 elderly intertrochanteric fractures underwent PFNA fixation were recruited. Mortality rate was identified until 9 years. We compared the survival time of hip fracture in each stage of CKD. A regression analysis was used to determine the association between risk factors and one-year mortality. The overall median survival time was 7.1 years. The Kaplan–Meier curve was significantly different in each CKD stage especially in CKD5. In addition, the incidence rate of mortality was highest in CKD 5 (17.4%) and the median survival time in CKD 5 was 3.3 years. The multivariate analysis demonstrated that heart disease, operative time > 60 min, presence of pulmonary embolism, and poor to fair Harris hip score were significantly increased mortality. CKD stage 5 is associated with the highest mortality rate and the shortest median time of survival during the 9-year follow up. Patients who have high risk should focus on long-term care planning, including the counseling for their healthcare providers and families.
