A joint dislocation, also called luxation, occurs when there is an abnormal separation in the joint, where two or more bones meet. [1] A partial dislocation is referred to as a subluxation . Dislocations are commonly caused by sudden trauma to the joint like during a car accident or fall.
In contrast to a luxation, which is a complete separation of the joint, a subluxation often returns to its normal position without additional help from a health professional. [6] An example of a joint subluxation is a nursemaid's elbow , which is the subluxation of the head of the radius from the annular ligament .
