What is the order of the secondary ossification centers within the pediatric elbow for CRITOE?

The secondary ossification centers of the pediatric elbow follow a specific order known as CRITOE, which stands for Capitellum, Radial head, Internal (or inner) epicondyle, Trochlea, and Olecranon. This hierarchical sequence is essential for understanding elbow development, particularly in the context of assessing growth and injuries in children.

The identified order begins with the Capitellum, which is the first to ossify, followed by the Radial head, which is the second. Next is the Inner epicondyle, which is significant in the context of ligament attachment and the development of functional elbow mechanics. After the inner epicondyle, the Trochlea ossifies, and lastly, the Olecranon appears.

Understanding the CRITOE sequence is crucial for clinicians dealing with pediatric elbow issues, as it aids in diagnosing and managing conditions such as osteochondritis dissecans or assessing for growth plate injuries. The correct answer reflects this established sequence of ossification centers.
