Definition
A floating shoulder injury is when two 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.
loating shoulder injuries are typically caused by a trauma like 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.
Causes
Floating shoulder injuries are typically caused by a trauma like 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.
Causes
Floating shoulder injuries are rare. They are caused by a high-impact trauma. Specific causes include:
- Motor vehicle accident
- Fall from a height
- Gunshot wound
- Crush injury
Risk Factors
A floating shoulder injury is a result of an accident or trauma. There are no known risk factors.
Symptoms
If you have any of these symptoms do not assume it is due to a floating shoulder. These may be caused by other conditions. Tell your doctor if you have any of these:
- Severe shoulder pain
- Muscle spasm
- Injured arm hangs lower than unaffected arm
- Bruising
- Swelling
- Numbness or weakness
Diagnosis
A doctor will ask how you were injured. A full physical exam will be done. Your shoulder will be examined more closely. The doctor may ask for a specialist to evaluate your shoulder. For example, an orthopedic surgeon specializes in bones.
Tests may include the following:
- X-rays —test that uses radiation to form an image; used to look at for broken bones in the shoulder
- CT scan —type of x-ray that uses computer to form an image; more sensitive than x-ray and used to look for broken bones in the shoulder
Treatment
The location and size of the broken bones 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:
Immobilization
A doctor may choose to use a sling or shoulder immobilizer. If this is the case you can expect to be in a sling or immobilizer for one to two months. Your doctor may suggest physical therapy to maintain shoulder range of motion.
Surgery
Surgical repair will mean inserting a plate and screws into the broken clavicle. Your scapular bone may also be fixed surgically. The surgeon will manually reposition your bones into their normal location during surgery. After surgery, your shoulder will be placed in a sling or shoulder immobilizer. Your doctor will give you instructions as to how long you need to wear it.
Rehabilitation
After surgery, your doctor will have you work with a therapist. The therapy will focus on regaining strength and range of motion to your shoulder.
Prevention
Floating shoulder injuries are a result of a traumatic injury. There are no known guidelines to prevent this type of injury.
