The acromioclavicular (AC) joint is located between the collarbone and the shoulder blade. It positions the shoulder correctly and helps it function to its fullest extent. An AC joint separation, commonly known as a shoulder separation, occurs when the collarbone goes out of alignment with the shoulder blade. This usually is a result of a fall directly onto the shoulder and is a common injury for athletes, especially cyclists who are involved in an accident or if they go over the handlebars.
