The tertiary fracture referred to here is potentially a fracture type III, which in the case of type III fractures is the most serious form of fracture and is further divided into two tertiary distinctions of open and closed types. The performance of the open type III is extensive soft tissue injury, but then there is a rupture in the soft tissue injury, an exostosis of the bone, and severe contamination of the bone surface, which is further divided into three subtypes A, B, and C according to the degree of contamination and their different degrees of soft tissue injury, gradually each form being more severely exposed and combined with vascular damage. In closed fractures type III is mainly a contusion of local muscles and skin, but there is no breakage of the skin and no bone leakage, which is a clearer indicator to distinguish open from closed. In closed type III injuries, there is a particular tendency to increase pressure after contusion of the soft tissues in the osteofascia and to develop what is often referred to as osteofascial compartment syndrome. These fractures are the most serious manifestation of the fracture type, whether open or closed, and it is important to treat the soft tissues to a certain level of stability before continuing to treat the fracture condition.
