Postoperative Complications of Hip Fractures in Patients with Chronic Kidney Disease

ABSTRACT

PURPOSE: The purpose of the present study was to evaluate the factors affecting the complications and the mortality rate after surgery for hip fractures in patients with chronic kidney disease. MATERIALS AND METHODS: We retrospectively analyzed 59 patients with chronic kidney disease and who were managed with surgical treatment after hip fracture between February 2001 and February 2007. The average age was 72 (range 45~83) years old. There were 21 men and 38 women. The postoperative complications and mortality rate were analyzed according to the patients' age and gender, the comorbid medical diseases, the preoperative pulmonary function tests, the timing of the operation and the operation methods, the American Association of Anesthetists score and the estimated glomerular filtration ratio (eGFR). RESULTS: For 59 patients with chronic kidney disease, the overall complication rate was 35.9% and the mortality rate was 15.3%. The patients with poor pulmonary function showed a high mortality rate in the postoperative period. The timing of the operation and the ASA score were associated with the postoperative complications rate and the mortality rate. CONCLUSION: Respiratory complications were dominant in the hip fracture patients with chronic kidney disease. The cause of death was mainly associated with pneumonia and a septic condition. Careful management must be done during the postoperative period to prevent infectious complications.
