Acromioclavicular (AC) joint injuries are common and often seen after bicycle wrecks, contact sports, and car accidents. The AC joint is located at the top of the shoulder where the acromion process and the clavicle meet to form a joint. Several ligaments surround this joint and depending on the severity...

The acromioclavicular (AC) joint is a diarthrodial articulation with an interposed fibrocartilaginous meniscal disk that links the hyaline cartilage articular surfaces of the acromial process and the clavicle. The joint is stabilized by a combination of dynamic muscular and static ligamentous structures, which allow a normal anatomic range of motion....

AC joint is situated between the clavicle and acromion;
- acromion has two ossification centers which fuse at age 22 yrs;
- it permits motion in three planes:
- AP gliding of acromion during...
