From 6 months to 12 years the cartilaginous secondary centres begin to ossify. The avulsed medial epicondyl was found within the joint and repositioned and fixated with K-wires. Be careful: in very young children the ossification within the cartilage of the capitellum might be minimal (ie normal and age related), and so is insufficiently calcified and does not allow application of the above rule. Fractures of the medial epicondyle make up approximately 12% of all pediatric elbow fractures.
