Dislocations are usually caused by a sudden impact to the joint. This usually occurs following a blow, fall, or other trauma.

Common causes of dislocations and subluxations include falls, motor vehicle accidents, sports, and horseplay. These activities may apply isolated or combined forces such as stretching, twisting, and compression to the affected joint.

A violent movement at the joint that exceeds normal limits usually causes a joint dislocation. Although dislocations often result from trauma, they sometimes occur as a result of disease affecting the joint structures.
