Elbow (medial oblique view)

Last revised by Andrew Murphy on 19 Sep 2021

The elbow medial oblique view is a specialized projection, utilized to demonstrate both the coronoid process in profile and the olecranon process sitting within the olecranon fossa of the humerus.

The medial oblique view is not a standard projection of the elbow, however helpful when occult fractures of the coronoid process are suspected.

  • the patient is seated alongside the table
  • fully extended arm and forearm, in a pronated position 
  • ensure the anterior portion of the elbow is roughly 45 degrees from the IR 
  • anteroposterior medial oblique projection
  • centering point
    • mid elbow joint
  • collimation
    • superior to the distal third of the humerus
    • inferior to include one-third of the proximal radius and ulna
    • lateral to include the skin margin 
    • medial to include medial skin margin 
  • orientation  
    • portrait
  • detector size
    • 18 cm x 24 cm
  • exposure
    • 50-60 kVp
    • 2-5 mAs
  • SID
    • 100 cm
  • grid
    • no 
  • the coronoid process should be seen in profile 
  • a clear visualization of the olecranon sitting in the olecranon fossa  
  • the radial head and proximal ulna are superimposed

Keep in mind patient comfort when performing this examination.
