Wound drains in proximal femoral fracture surgery: a randomized prospective trial of 177 patients.

We report on the effect of wound drains on wound healing following surgery for proximal femoral fractures. One hundred and seventy-seven patients undergoing AO dynamic hip screw (DHS) or hemiarthroplasty were randomized whether or not to receive wound drainage. Patients who received wound drainage showed statistically better wound healing in terms of the ASEPSIS wound scoring system and a reduced infection rate. This study conflicts with previous smaller studies which failed to show an effect of wound drainage upon wound healing.
