[edit] CRITOE

  • C: Capitellum
  • R: Radial head
  • I: Internal (medial) epicondyle
  • T: Trochlea
  • O: Olecranon
  • E: External (lateral) epicondyle

  • CRITOE is the order in which the ossification centers of the elbow appear.
  • Ossification centers may be mistaken for fractures on x-ray.
  • General rule of thumb for the time of appearance of the ossification centers is "1-3-5-7-9-11," which are the ages in years that the ossification centers appear, corresponding to the CRITOE.
