Final answer:
A comminuted fracture is the type that results in several bony fragments, occurring when the bone is broken into many small pieces due to high-impact trauma.
Step-by-step explanation:
The type of fracture that results in several bony fragments is the comminuted fracture. In a comminuted fracture, the bone is shattered into many small pieces, which can occur when an extreme force is applied. This is different from other types of fractures, such as a spiral fracture, which is caused by a twisting force; a greenstick fracture, where the bone bends and cracks, usually seen in children; and a transverse fracture, which has a horizontal fracture line.
Fractures can be classified into different types based on their complexity, location, and characteristics. For instance, a transverse fracture occurs straight across the long axis of the bone. An open fracture, also known as a compound fracture, is one where the bone breaks through the skin, which poses a high risk of infection. Healing of fractures generally involves the formation of a hematoma, followed by internal and external calli, with osteoblasts and osteoclasts rebuilding the bone tissue.
