Final answer:
A partial fracture in which one side of the bone is broken and the other side bends, known as a greenstick fracture, occurs only in children with bones that are still developing. Various types of fractures include transverse, oblique, spiral, comminuted, impacted, and open fractures. It's imperative for fractures to be set correctly to avoid deformities.
Step-by-step explanation:
The subject in question refers to a specific type of bone fracture that occurs only in children, which is indicative of the biology subject at a middle school level. In children, whose bones are still developing and are not fully ossified, a unique type of fracture can occur. This is called a greenstick fracture, where one side of the bone is broken and the other side bends. Different Fracture Patterns are
- A fracture that occurs straight across the long axis of the bone is known as a transverse fracture.
- When a fracture occurs at an angle that is not 90 degrees, it is called an oblique fracture.
- Twisting motions can cause spiral fractures, where bone segments are pulled apart.
- A comminuted fracture features several breaks, resulting in many small pieces between two large segments.
- An impacted fracture happens when one fragment is driven into another, usually due to compression.
- An open fracture, or compound fracture, occurs when at least one end of the broken bone tears through the skin, increasing the risk of infection.
Bones can fracture under excessive bending stress, similar to how a pencil breaks when bent too far. Additionally, a bone healing process without correct resetting can lead to permanent deformities.
