What defines an open fracture?

An open fracture, often referred to as a compound fracture, is characterized by the fact that the broken bone has pierced through the skin. This exposure can lead to a higher risk of infection due to the potential for bacteria to enter the body through the open wound. Recognizing an open fracture is vital as it often requires immediate medical attention and a distinct approach to treatment compared to closed fractures, where the skin remains intact.

On the other hand, a fracture where the skin is intact points to a closed fracture, which, while still serious, poses different risks and considerations for treatment. Fractures that occur in multiple places refer to comminuted fractures, while dislocation involves the displacement of bones at a joint rather than an actual fracture of the bone itself. Thus, the key defining feature of an open fracture is the breaking of the bone along with a break in the skin, highlighting its severity and the need for careful management.
