A floating shoulder injury is when 2 of the shoulder bones are broken. The clavicle bone (collarbone) and the upper part of the scapula bone (shoulder blade) break. These breaks cause the shoulder to pull out of place and look like it is floating.

Floating shoulder injuries are typically caused by severe trauma like what might occur in a car accident. You will likely be taken to an emergency room. You will be evaluated from head to toe. If you are experiencing shoulder pain or your shoulder looks out of place, your doctor will look for a floating shoulder injury.

Floating shoulder injuries are rare. They are caused by a high-impact trauma. Specific injuries may be the result of:

  • Motor vehicle accident
  • Fall from a height
  • Gunshot wound
  • Crush injury
  • Bicycle accident

  • Injured arm hangs lower than unaffected arm
  • Bruising
  • Swelling
  • Numbness or weakness

The location and size of the broken bones, and how severe your other injuries are will determine the options. A floating shoulder may be treated medically or surgically. Talk with your doctor about the best plan for you. Treatment options include the following:

A doctor may choose to use a sling or shoulder immobilizer. If this is the case, a sling may need to be worn for 1-2 months. Your doctor may suggest physical therapy to maintain shoulder range of motion.

Surgical repair will mean inserting a plate and screws into the broken clavicle. The scapular bone may also be fixed surgically. The bones will be manually repositioned into their normal location during surgery. After surgery, the shoulder will be placed in a sling or shoulder immobilizer.

After surgery, a therapy will focus on regaining strength and range of motion to the shoulder.


Floating shoulder injuries are a result of a traumatic injury. There are no known guidelines to prevent this type of injury.
