OBJECTIVE: Vacuum-assisted closure (VAC) is an interventional, proactive injury treatment technique that exposes the wound bed to localized sub-atmospheric pressure, drains fluid from the extracellular space, enhances circulation, and promotes the growth of granulation tissue. The study goal is to determine how frequently wounds become infected, how long it takes to prepare a wound for skin-covering procedures, and how long it takes for a uniform granulation tissue bed to form in wounds that are being treated with vacuum-aided closure after main fracture fixation
