So I blew a roll in aikido and landed on my shoulder. It hurt like hell, but I got these cool x-rays as result. Films are of the right shoulder, ventral and inferior views. Diagnosis is class 1 or 2 acromioclavicular strain (AC strain) aka a mildly sepparated shoulder. You can see how the clavicle (collar bone) is sepparated from and raised a bit above the acromion (a hook of bone from the scapula (shoulder blade) which forms the backside of the shoulder girdle).
