Subluxation occurs when a bone is partially pulled or pushed out of place (out of its normal relationship to the other bones that make up a joint). This can happen in joints such as the kneecap, hip, finger, elbow, or shoulder.
A subluxation may be caused by a direct blow to the joint, a fall, or a sudden twisting movement. Everyday activities may cause this injury if a person has unstable joints. A subluxation in a young child may be caused by abuse.
Although a subluxation may feel better because the dislocated bone has partially popped back into place, it can still be a problem that needs medical evaluation.
Soft tissues in or around a joint (such as ligaments, tendons, muscles, cartilage, and the joint capsule) may stretch or tear.
Nerves and blood vessels may be damaged by the injury.
