- 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.
