Abstract

PURPOSE
The purpose of this study was to compare with general characteristics affecting ambulatory recovery at one-year after the fixation of intertrochanteric fracture with proximal femoral nail (PFN) of elderly patients over the age of 65 years.
MATERIALS AND METHODS
Between September 2008 and September 2015, 152 patients were diagnosed with femoral intertrochanteric fracture in Dong-Eui Medical Center. Of these patients, 75 were available in this retrospective study. Multivariate linear regression analysis, using a stepwise selection method, were performed to identify the prognostic factors affecting one-year postoperative recovery of ambulatory status, such as pre-injury ambulatory status, gender, age, fracture type, associated underlying disease, American Society of Anesthesiologists (ASA) grade, dementia, and complication.
RESULTS
A decrease in the one-year postoperative ambulatory status was 68% and pre-injury ambulatory status was regained in 32% of patients. The pre-injury ambulatory status was the most important determinant of one-year postoperative recovery of ambulatory status. The ASA grade and complication were also predictors of recovery of ambulatory status.
CONCLUSION
Pre-injury ambulatory status, ASA grade and complication were prognostic factors associated with one-year postoperative recovery of ambulatory status after fixating the intertrochanteric fracture using PFN in elderly patients over the age of 65 years.
