Athlete undergoing shoulder examination after an AC joint injury.

Acromioclavicular Dislocation

Acromioclavicular (AC) dislocation occurs when the collarbone separates from the shoulder blade at the AC joint. This injury is common in contact sports and falls.

Quick Facts

  • Condition: Separation of the AC joint.
  • Symptoms: Pain, swelling, visible deformity.
  • Severity: Ranges from mild sprains to complete dislocations.
  • Treatments: Rest, physical therapy, or surgery.

Anatomy & Condition

The AC joint connects the clavicle to the scapula, allowing arm movement. Dislocation disrupts this connection, leading to pain and limited function.

Symptoms & Causes

Symptoms include swelling, tenderness, and a visible “bump” at the shoulder. Injuries typically occur due to direct blows or falls.

Treatment & Recovery

Mild cases are treated with rest and bracing. Severe dislocations may require surgical reconstruction of the joint using grafts or implants.

FAQ

Can I return to sports after an AC dislocation?
