What is a Fracture?
Article featured on MedicalNewsToday
A bone fracture is a crack or break in a bone. Bone fractures usually result from a high force impact or stress. People with osteoporosis or bone cancer may experience a fracture with very little impact.
A fracture that results from a medical condition that weakens the bones is called a pathological fracture.
In this article, we detail the different types of bone fractures, their various causes, and the treatments available.
What is a bone fracture?
A bone fracture is a full or partial break in the continuity of bone tissue. Fractures can occur in any bone in the body.
There are several different ways in which a bone can fracture. For example, a closed fracture is a break to the bone that does not damage surrounding tissue or tear through the skin.
By contrast, a compound fracture is one that damages surrounding tissue and penetrates the skin. Compound fractures are generally more serious than simple fractures due to the risk of infection.
Types
There are a number of other fracture types, including:
- Avulsion fracture: A muscle or ligament pulls on the bone, fracturing it.
- Comminuted fracture: An impact shatters the bone into many pieces.
- Compression, or crush, fracture: This generally occurs in the spongy bone in the spine. For example, the front portion of a vertebra in the spine may collapse due to osteoporosis.
- Fracture dislocation: This occurs when a joint dislocates, and one of the bones of the joint fractures.
- Greenstick fracture: The bone partly fractures on one side but does not break completely, because the rest of the bone can bend.
- Hairline fracture: This is a thin, partial fracture of the bone.
- Impacted fracture: When a bone fractures, a piece of the bone may impact another bone.
- Intra-articular fracture: This occurs when a fracture extends into the surface of a joint.
- Longitudinal fracture: This is when the fracture extends along the length of the bone.
- Oblique fracture: An oblique fracture is one that occurs opposite to a bone’s long axis.
- Pathological fracture: This occurs when an underlying condition weakens the bone and causes a fracture.
- Spiral fracture: Here, at least one part of the bone twists during a break.
- Stress fracture: Repeated stress and strain can fracture a bone. This is common among athletes.
- Transverse fracture: This is a straight break across the bone.
Symptoms
Symptoms of a fracture vary depending on its location, a person’s age and general health, and the severity of the injury.
However, people with a bone fracture will typically experience some of the following:
In more severe cases, a person may experience:
- dizziness
- faintness or lightheadedness
- nausea
Causes
Healthy bones are extremely resilient and can withstand surprisingly powerful impacts. However, under enough force, they may crack or break.
Physical trauma, overuse, and health conditions that weaken the bones, such as osteoporosis, are the leading causes of bone fractures. Other factors can also increase an individual’s risk of sustaining fractures.
A person’s bones will typically weaken with age, which increases the risk of them breaking. As a person ages, the likelihood of their developing a condition that weakens the bones is also greater.
