Although it takes a large amount of force to dislocate a joint for the first time, any kind of extreme or sudden movement of the joint in an unusual direction can lead to dislocation. Due to its flexibility, the shoulder can be dislocated in multiple directions and sometimes it does not dislocate all the way. During dislocation, the muscles around the socket may be damaged or torn sometimes leading to other complications.
Depending on the severity of the dislocation treatment options vary. The bone should be put back into the socket by a professional and then the shoulder should be compressed and iced to keep down swelling and reduce pain. This, in combination with over-the-counter medications, will sometimes be enough for a complete recovery. If the condition is extreme, surgery may be required.
The only way to prevent shoulder dislocation is to take precautions when involved with any sport or high-risk activities. Make sure to wear the correct protection and when falling do not use your arms to brace yourself, instead tuck your head and arms in toward your chest. If you have already experienced dislocation make sure to know the limits of your shoulder and protect your joints.
