The difference between a sprain and a dislocation is that the first bone position is unchanged, while the dislocation bones are separated and that separation greater than normal can be seen on a radiograph.

Essentially forcing the ceiling of joint movement. The most common mechanisms by which it produces are:

1. The excessive jerky movements, which are beyond the range of motion that allows the joint, so that is stretched or torn ligament that holds the two bones.
2. Accidents typically car in the outer movements are combined with external forces.

The most common location is usually the ankle. Faced with a twist has to follow the pattern with the acronym RICE: rest, ice (ice), compression and elevation. First, do not walk when you have a sprained ankle. Second, apply an ice bag or wrapped in a handkerchief during the first 6 hours. Third, put a layer of mulch that serves as cotton, then make a firm bandage always starting from the toes to the ankle and then up toward the leg in a circular motion. Fourth, keep your foot elevated and does not rest on the ground.
