The bones of the skeleton are connected with each others by joints. Joint surfaces are covered by cartilages to enable them to move freely. In most cases the bones within joints are bound together by cartilages and ligaments. By the aid of these movements are supported and controlled.
A dislocation is a displacement of one or more of the bones forming a joint. The joints which are most commonly dislocated are those of the shoulder, lower jaw, elbow, and fingers. Dislocation is often the result of some injury by external force, where by the ends of the bones forming the joint become separated. The joint is moved beyond its normal range.
A fracture- dislocation donates fracture near the dislocated end of one of the bones.
Congenital dislocations are those with which a baby is born. E.g. hip joint.
Dislocations due to injury are the form commonly seen.
Pathological dislocation occurs in certain diseases which may affect the joint, cavities or the supporting structures.
The symptoms of dislocation are pain and inability to use the joint and the head of the bone may be felt to be in an unnatural place. The limb is shortened, lengthened, or deformed, and the joint may be deformed. They may be associated with pain and swelling.
It is important to reduce a dislocation as soon as possible after the injury because after sometime considerable swelling of the part may occur and obscure the diagnosis. The displacement may cause injury to the surrounding parts by pressure and it is much more difficult to reduce a dislocation later. Anesthetists help is usually required to permit sufficient relaxation of the muscles to enable the bones to be reduced.
