Final answer:
The four major types of skeletal trauma are transverse, oblique, spiral, and comminuted fractures, which can vary in severity and treatment approaches.
Step-by-step explanation:
Four Major Types of Skeletal Trauma
The four major types of skeletal trauma include the following types of fractures: transverse, oblique, spiral, and comminuted fractures. Transverse fractures involve a straight line perpendicular to the bone's long axis. Oblique fractures are angled and can be more unstable depending on the angle of the break. Spiral fractures result from a twisting force and are characterized by a helical fracture line. Comminuted fractures occur when the bone shatters into multiple pieces, often due to a high-impact force. Each type of fracture can result from different mechanisms and can vary in severity, requiring different treatment approaches such as closed reduction, where the bone is realigned without surgery, or open reduction, which involves surgical intervention.
