Separated Shoulder (AC Joint Separation)

A separated shoulder, also known as an AC (acromioclavicular) joint separation, occurs when the ligaments connecting the collarbone to the shoulder blade are stretched or torn. This injury is common in contact sports and falls directly onto the shoulder.

Symptoms often include pain at the top of the shoulder, swelling, and difficulty lifting the arm. Supportive bracing may help protect the joint and improve comfort during recovery.

Common AC joint symptoms

• Pain at the top of the shoulder
• Visible bump near the collarbone
• Swelling and tenderness
• Pain with overhead or cross-body movement

Choosing the right support

Mild separations may be managed with a sling during early recovery. Functional shoulder braces may help limit excessive movement and improve stability during return-to-sport phases.
