Final answer:
A comminuted fracture is a type of bone fracture that results in several bony fragments, distinguishing it from the greenstick, compound, and stress fractures.
Step-by-step explanation:
A complete fracture resulting in several bony fragments is known as a comminuted fracture. In contrast to other types, such as the greenstick fracture, compound fracture, and stress fracture, a comminuted fracture specifically denotes a situation where the bone is broken into more than two fragments.
The body attempts to heal fractures through a natural process that involves the formation of a hematoma, followed by the development of internal and external calli. Osteoclasts aid in resorbing dead bone, whereas osteoblasts work to create new bone to replace cartilage. This natural repair process eventually leads to the unification of the calli and the complete remodeling and healing of the fracture.
