dislocation (redirected from compound dislocation)

dislocation, displacement of a body part, usually a bone. When a bone is dislocated, the ends of opposing bones are usually forced out of connection with one another. In the process, bruising of tissues and tearing of ligaments may occur. The condition may be congenital, but usually it is the result of injury. In some persons recurrent dislocation, usually of the jaw or of the knee, is brought on by only slight provocation. Manipulation, bandages, splints, and other appliances are used to reposition the dislocated part. Occasionally corrective surgery may be required.

dislocation

Displacement of the bones of a joint. It disrupts the ligaments, muscles, and capsule (encasing membrane) holding the joint in place. The joint, painful and tender, appears misshapen and swollen, with discoloration of the overlying skin. The patient cannot use the joint and often feels a grating or grinding sensation on trying to move it. The bones must be returned to their normal position (reduction) and the joint kept immobile until healed. Recurrent and congenital dislocations usually require surgical reconstruction.
