Pediatric Elbow Trauma. Only the capitellum ossification center (C) is visible. On a lateral view the trochlea ossifications may project into the joint. 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. The Trochlea has two or more ossification centres which can give the trochlea a fragmented appearance. Olecranon fractures in children are less common than in adults.

Distention of the joint will cause the anterior fat pad to become elevated and the posterior fat pad to become visible. If part of the epicondyle is covered by part of the humeral metaphysis then an avulsion has not occurred. They occur between the ages of 4 and 10 years. 5. If there is more than 30?

For example, if a trochlear ossification center in an 8-year-old child is seen on x-ray but the internal (medial) epicondyle ossification center is not found, then one must suspect a medical epicondyle ossification center fracture-dislocation that displaced it from its normal anatomical location.
