  2. Olecranon fossa
  3. Lateral epicondyle
  4. Medial epicondyle
  5. Capitellum
  6. Radial head

A/P Elbow Xray A/P Elbow through a ROM from full suppination to full pronation.

Red dot indicates position of radial tuberosity which moves from:

  • Anterior position in suppination
  • Posteromedial in neutral rotation
  • Lateral in pronation

Lateral Elbow Xray Lateral Elbow through a ROMfrom full suppination to full pronation.

Red dot indicates position of radial tuberosity which moves from:

  • Anterior position in suppination
  • Posteromedial in neutral rotation
  • Lateral in pronation
  Radial Head-Capitellum view
  • Demostrates: Unobstructed view of radial head, capitellum, coronoid process, humeroradial/humeroulnar articulations • anteroinferior glenoid rim.
  • Helpful for:

Postion: patient seated with forarm resting on the xray table on its ulnar side; elbow flexed 90°; thumb pointing up.
Beam: aimed at 45° angle from the forearm towards radial head
  Oblique - Olecranon osteophytes

An oblique axial view with the elbow in 110° of flexion best demonstrates posteromedial olecranon osteophytes.
