The acromio-clavicular (AC) joint fracture can happen in one of the two bones that make the AC joint fracture. It can range from a small crack to a complete bone fracture. The AC joint fracture can happen because of a shoulder injury or a fall on the shoulder.
Symptoms usually include pain and swelling. A visible deformity can be seen from the skin if the fracture is complete.
The diagnosis can be performed clinically with a physical examination. X-rays are necessary when the fracture is open, comminuted or when it involves multiple bones to help dress the treatment plan.
The usual treatment involves immobilizing the shoulder with a splint and anti-inflammatories. Mild fractures can resolve well to the conservative treatment. In severe cases, your surgeon may discuss surgery to make the fractured bones heal properly.
