Studies has shown that there is no additional benefits of risk of infection when giving antibiotics for one day, when compared to giving antibiotics for three days or five days. However, at present, there is only low to moderate evidence for this and more research is needed. Some authors recommended that antibiotics to be given for three doses for Gustilo Grade I fractures, for one day after wound closure in Grade II fractures, three days in Grade IIIA fractures, and three days after wound closure for Grade IIIB and IIIC. Wound irrigation
There has been no agreement for the optimal solution for wound irrigation. Studies found out that there is no difference in infection rates by using normal saline or other various forms of water (distilled, boiled, or tap). There is also no difference in infection rates when using normal saline with castile soap compared with normal saline together with bacitracin in irrigating wounds. Studies also have shown that there is no difference in infection rates using low pressure pulse lavage (LPPL) when compared to high pressure pulse lavage (HPPL) in irrigating wounds. Optimal amount of fluid for irrigation also has not been established. It is recommended that the amount of irrigation solution to be determined by the severity of the fracture, with 3 litres for type I fractures, 6 litres for type II fractures, and 9 litres for type III fractures. Wound debridement
The purpose of wound debridement is to remove all contaminated and non-viable tissues including skin, subcutaneous fat, muscles and bones.
An open fracture, also  called a compound fracture, is a type of bone fracture in orthopedics that is frequently caused by high energy trauma. It is a bone fracture associated with a break in the skin continuity which can cause complications such as infection, malunion, and nonunion. Gustilo open fracture classification is the most commonly used method to classify open fractures, to guide treatment and to predict clinical outcomes. Advanced trauma life support is the first line of action in dealing with open fractures and to rule out other life-threatening condition in cases of trauma. Cephalosporins are generally the first line of antibiotics. The antibiotics are continued for 24 hours to minimize the risk of infections. Therapeutic irrigation, wound debridement, early wound closure and bone fixation are the main management of open fractures. All these actions aimed to reduce the risk of infections. Causes
Open fractures can occur due to direct impacts such as high-energy physical forces (trauma), motor vehicular accidents, firearms, and falls from height. Indirect mechanisms include twisting (torsional injuries) and falling from a standing position. These mechanisms are usually associated with substantial degloving of the soft-tissues, but can also have a subtler appearance with a small poke hole and accumulation of clotted blood in the tissues. Depending on the nature of the trauma, it can cause different types of fractures:

Common fractures
Result from significant trauma to the bone. This trauma can come from a variety of forces – a direct blow, axial loading, angular forces, torque, or a mixture of these.
