denotes a displacement of one joint
surface in relation to the other which results in a loss of joint contact between them. Dislocation is often caused by trauma and displacement is permanent in the absence of care and adversely affects the functionality of the joint. It can also be a side-effect
of ligamentous laxity. It usually causes pain
and prevents normal joint movement. Dislocation is sometimes accompanied by a ligament
tear. The two articular surfaces must be put in place quickly. The replacement of a dislocation is often painful and can be performed under analgesics
, relaxing gas often in children, or general anesthesia
for the major dislocation of a large joint. Immobilization of the joint is often necessary afterwards. Dislocations of the shoulder
, a finger, or even the jaw are quite common. The absence of a complete loss of contact is called subluxation.
