How can you fix compound/open fracture?

It depends. Based on the degree of soft-tissue injury, type of fracture, and level of contamination of the open wound, decisions for the optimal treatment can be made. These can range from surgical cleansing and debridement to non-operative wound care and fracture management. Antibiotics are typically given. It is important to see an orthopedic specialist as soon as possible to discuss the best treatments.
