An avulsion fracture occurs when bone fragments are torn from their original position. It can occur by a violent contraction of the muscle, causing it to tear away part of the bone attached to the muscle. . This fracture is common in the knee and shoulder joints. An impacted fracture is a condition in which one of the broken fragments of the bone becomes stuck in another bone. This fracture usually occurs in an area of ​​spongy bone.
