Clavicle series

The radiographic series of the clavicle is utilized in emergency departments to assess the clavicle, acromioclavicular and sternoclavicular joint.  

Indications

Clavicle x-rays are indicated for a variety of settings including:

• trauma
• bony tenderness
• suspected fracture 
• congenital abnormalities 
• obvious deformity

Projections

Standard projections

• AP
  • demonstrates the entire clavicle including its articulation with the acromion and the sternum 
• AP cephalad angulation
  • 'straightens' out the clavicle
  • often used to better visualize occult clavicle fractures 

Modified trauma projections

• supine 
  • AP clavicle performed supine, with or without angulation

Additional projections

• AP frontal projection with further cephalad angulation visualizes the under the surface of the clavicle
• AP frontal projection with caudal angulation visualizes the posterior surface of the clavicle
• bilateral views may be required if there is a need for comparison or there is suspicion of a bilateral process
