Separated shoulders often occur in people who participate in sports such as American football, soccer, horseback riding, hockey, mountain biking, biking, roller derby, rowing, and rugby. The dislocation is classified into 6 types, with 1 through 3 increasing in severity, and 4 through 6 being the most severe. The most common mechanism of injury is a fall on the tip of the shoulder or also a fall on an outstretched hand (FOOSH). In falls where the force is transmitted indirectly, often only the acromioclavular ligament is affected, and the coracoclavicular ligaments remain unharmed.  In hockey, the<unk>  is sometimes due to a lateral force, as when one gets forcefully checked into the side of the rink.
