Skipped Ossification Center

Donna Mohseni Mofidi, Lubna Siddiqi and Ian Ross


There are six secondary ossification centers in the elbow that regularly ossify in a predictable order. The mnemonic CRITOE is used to identify the order of ossification. CRITOE stands for: Capitellum, radial head, internal epicondyle, trochlea, olecranon and external epicondyle. Knowledge of the order of ossification in useful to avoid mistaking an ossification center for a bony fragment in pediatric elbow injuries. Presented below is a case that deviates from the typical ossification order of CRITOE. A 5-year-old female presented with an ossified capitellum and internal epicondyle, but the radial head ossification was not present
