Introduction: The closed suction drainage system is widely used in proximal femur surgeries. Recently, the proximal femoral nail antirotation (PFNA) system was advocated for treating intertrochanteric fractures (ITFs) in the elderly patients. However, the true effect of the closed suction drainage system with PFNA fixation on outcomes in ITFs is still unknown. This prospective randomized controlled trial aimed to examine whether routine drainage is useful for PFNA fixation in ITFs. Methods: A total of 80 patients with acute ITFs were treated with closed or mini-open reduction with PFNA fixation at the National Cheng Kung University Hospital and 60 eligible patients (22 men and 38 women) were randomized for whether to receive suction drainage. In clinical outcomes, the visual analog scale (VAS), morphine equivalent dosage, injured thigh width, body temperature, and wound condition with specific reference to hematoma formation and wound infection were measured on postoperative days 1, 2, 4, and 10. In laboratory outcomes, the investigators evaluated hemoglobin and hematocrit levels postoperatively at different time points. Blood transfusion and total blood loss (TBL) were measured by Mercuriali's formula in millimeter.
