Cause of fracture
- Aug 30, 2018 -

A fracture can be caused by a traumatic or skeletal disease, and a fracture caused by a bone disease is called a pathological fracture. The causes of fractures mainly include the following.

1. Direct violence Violence directly affects fractures at the injured site, and fractures and trauma occur at the same level. Often accompanied by soft tissue damage there.

2. Indirect violence Violence is caused by conduction, lever, rotation or muscle contraction to cause the fracture to occur outside the point of violence. The fracture and external force are not in the same part. If the ankle sprains, the conduction of force leads to fractures of the internal and external tendons.

3. Accumulative strain Long-term, repeated, slight direct or indirect stress on the bone caused by a part of the limb, also known as fatigue fracture. For example, the second and third metatarsal bones and the lower third of the humerus fractures. There is often no significant displacement of the fracture.

4. Skeletal diseases A fracture caused by a small external force caused by bone destruction (such as osteomyelitis, osteoporosis, bone tumor, etc.), which is caused by a small external force, is called a pathological fracture.
