CIEMT Trauma and Assessment Practice Exam

Fracture orientation relative to the bone’s long axis is the key idea. A straight across fracture is a transverse fracture, meaning the break runs perpendicular to the bone’s long axis and appears as a straight, horizontal line across the bone on X-ray. This pattern usually results from a direct force applied across the bone or a bending force that shears straight across, producing a clean crosswise break. It contrasts with oblique fractures, where the break slopes at an angle, greenstick fractures where the bone is bent and only one side cracks while the other buckles (incomplete fracture, common in children), and comminuted fractures where the bone is broken into multiple pieces. Understanding the orientation helps anticipate stability and guide treatment.
