Understanding Dislocation - the Basics

What Is a Dislocation?

Falling off a bike, pitching a softball -- these are all instances when a joint can become dislocated. Basically, "dislocation" means that the bones that form the joint have slipped out of their normal position in the joint. Any kind of trauma -- like a fall, a blow, or strain -- can cause a dislocation. Dislocations can occur in the large joints -- shoulder, hip, knee, elbow and ankle -- or in the smaller joints -- fingers and toes.

Sometimes, the bones of the joint will shift, but not totally become dislocated.This is called subluxation (slippage) and can be a chronic problem. While the bones will shift back into their original position, you may feel some pain and have some bruising until they do.

It often is difficult to tell whether the injury is a dislocated joint or a broken bone. Both are considered emergency situations requiring immediate medical attention.
