Afracture is defined as:
the displacement of a bone from a joint
the tearing or stretching of the ligaments and tendons that support a joint
a broken, cracked, or chipped bone
torn or stretched muscles

The correct option is "a broken, cracked, or chipped bone"

A bone fracture is a medical condition in which there is a partial or complete break in the continuity of the bone. In the most serious cases, this can be broken into several pieces. They can be the result of a blow, force or traction of great force, or injury from minimal trauma as a result of certain disorders that weaken bones, such as osteoporosis, osteopenia, undiagnosed celiac disease, bone cancer or osteogenesis imperfect, in which case it is called a pathological fracture.
