Determinants of Dehiscence and Wound Infections After Open Reduction and Internal Fixation of Femoral Shaft and Subtrochanteric fractures.

PURPOSE: Open Reduction and Internal Fixation of the Femur (ORIF) is a surgical procedure which carries risk for complications including wound dehiscence and postoperative surgical site infections. This study aims to identify significant predictors of wound dehiscence, deep wound surgical site infection, organ/space surgical site infection within 30 days of ORIF for femoral shaft and subtrochanteric fractures. METHODS: The American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) data registry was used to collect data on significant independent risk factors associated with the complications of interest within 30 days of operation. The ACS NSQIP was filtered to examine the outcome of dehiscence, superficial space, deep space, and organ space infections following ORIF. The following variables were tested for significance: Age, Sex, BMI, ASA classification, total operating time, anesthesia type, diabetes, preoperative steroid use, functional status, dialysis, cancer, hypertension requiring medication, preoperative albumin, preoperative platelets, and preoperative WBC. RESULTS: The 30-day odds of wound dehiscence were significantly associated with higher BMI (p=0.004) and chronic steroid use (p=0.011). Significant predictors of deep incisional SSI included operative time (p
