Last revised by Dr Naim K on 20 Jan 2021

Mnemonics for elbow ossification include CRITOE and CRITOL. These are essentially the same, apart from the terminal letter which represents the External or Lateral epicondyle.

Mnemonics

CRITOE
CRITOL

CRITOL is the same as CRITOE apart from the final letter, which refers to the lateral epicondyle rather than external.
