Final answer:
Pathological is the odd one out among Spiral, Oblique, and Transverse fractures when considering fractures caused by trauma. Pathological fractures occur in diseased bones, while the other types are due to direct injury.
Step-by-step explanation:
If a fracture has been caused by trauma, the odd one out among Spiral, Oblique, Pathological, and Transverse fractures would be Pathological. Spiral, Oblique, and Transverse fractures are all types that can occur due to a traumatic event such as a fall or a direct impact. On the other hand, Pathological fractures occur in bones that are weakened by diseases such as cancer or osteoporosis and may break with minimal or no trauma.
Key characteristics of these fractures are as follows:
- Spiral - Bone segments are pulled apart as a result of a twisting motion.
- Oblique - Occurs at an angle that is not 90 degrees to the long axis of the bone.
- Transverse - Occurs straight across the long axis of the bone.
- Pathological - Occurs in bones already weakened by disease.
Understanding these fracture types helps in their identification and the application of appropriate treatment, such as closed or open reduction, followed by the healing process which includes the formation of calli and the remodeling of new bone.
