Trauma to the shoulder is common. Injuries range from a separated shoulder resulting from a fall onto the shoulder to a high-speed car accident that fractures the shoulder blade (scapula) or collar bone (clavicle).  Fractures commonly involve the clavicle (collar bone), proximal humerus (top of the upper arm bone), and scapula (shoulder blade).


Fractures of the clavicle or the proximal humerus can be caused by a direct blow to the area from a fall, collision, or motor vehicle accident.  Fractures to the proximal humerus can be the result of weak bones as seen in osteoporosis and are more common in older people

Because the scapula is protected by the chest and surrounding muscles, it is not easily fractured. Therefore, fractures of the scapula are usually caused by high-energy trauma, such as a high speed motor vehicle accident. Scapula fractures are often associated with injuries to the chest.

Symptoms of Fractures

Symptoms of fractures about the shoulder are related to the specific type of fracture.

General Findings

  • Pain
  • Swelling and bruising
  • Inability to move the shoulder
  • A grinding sensation when the shoulder is moved
  • Deformity -- "It does not look right"

Specific Findings: Clavicle Fracture

  • Swelling about the middle of the collarbone area
  • An area that may have a "bump," which is actually the prominent ends of the fracture under the skin
  • Shoulder range of motion is limited, although not as much as with fractures of the proximal humerus

Specific Findings: Proximal Humerus Fracture

  • A severely swollen shoulder
  • Very limited movement of the shoulder
  • Severe pain

Specific Findings: Scapular Fracture

  • Pain
  • Swelling
  • Severe bruising about the shoulder blade


Most fractures are diagnosed with X-rays of the area and by physical examination. Sometimes, additional imaging techniques, such as computed tomography or “cat scans”, are necessary.

Treatment Options

Clavicle Fractures

Some clavicle fractures can be treated without surgery. Surgery is necessary when there is a compound fracture that has broken through the skin or the bone is severely out of place. Surgery typically involves fixing of the fracture with plates and screws or rods inside the bone.

Proximal Humerus Fractures

Most fractures of the proximal humerus can be treated without surgery if the bone fragments are not shifted out of position (displaced). If the fragments are shifted out of position, surgery is usually required. Surgery usually involves fixation of the fracture fragments with plates, screws, or pins or it involves shoulder replacement.

Scapula Fractures

Most fractures of the scapula can be treated without surgery. Treatment involves immobilization with a sling or shoulder immobilizer, icing, and pain medications. The patient will be examined for additional injuries.

About 10% to 20% of scapula fractures need surgery. Fractures that need surgery usually have fracture fragments involving the shoulder joint or there is an additional fracture of the clavicle. Surgery involves fixation of the fracture fragments with plates and screws.


Life after a shoulder fracture can be greatly affected for several weeks or even months. Most shoulder injuries whether treated surgically or nonsurgically require a period of immobilization followed by rehabilitation.

If the injury was not severe, there is fairly rapid improvement and return of function after the first 4 to 6 weeks. Shoulder exercises, usually as part of a supervised physical therapy program, are usually necessary. Exercises decrease stiffness, improve range of motion, and help the patient regain muscle strength.
