Ossification centres around elbow appear in the following order:
Remember CRMTOL or CaRaMel TOffEE 1-3-5-7-9
Capitellum - 1 yr
Radial head - 3 yrs
Medial epicondyle - 5 yrs
Trochlea - 7 yrs
Olecranon - 9 yrs
Lateral epicondyle = External Epicondyle
Note: An alteranate mnemonic is CRITOE, where I = Internal Epicondyle.
You can imagine a child putting Caramel toffee into his mouth with elbow flexed.
