> Out with acromioclavicular dislocation  (Crash in X²O Badkamers Trofee Azencross - Loenhout)
< Acromioclavicular dislocation is an injury where the collarbone (clavicle) separates from the shoulder blade at the acromioclavicular joint, typically after a direct blow or fall, causing pain, swelling, tenderness, and sometimes a visible bump, with the joint stabilized by the acromioclavicular and coracoclavicular ligaments.
