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. Medial Epicondyle avulsion (5).An avulsed fragment that is located within the joint can give diagnostic problems. Normal alignment: when drawn along the anterior cortex of the humerus, in most normal patients at least one third of the ossifying capitellum lies anterior to this line.

The mechanism that causes these stressfractures on the medial side is the same mechanism that causes a osteochondritis of the capitellum due to impaction on the lateral side. Regularly overlooked injuries 25% will show radiocapitellar line slightly lateral to center of capitellum. Positive fat pad sign (2)Any elbow joint distention either hemorrhagic, inflammatory or traumatic gives rise to a positive fat pad sign. The low position of the wrist leads to endorotation of the humerus. The diagnosis can be challenging since the distal humeral epiphysis is cartilaginous and not visualized on x-rays. Since the medial epicondyle is an extra-articular structure a fracture or avulsion will not automatically produce a positive fat pad sign.

Hence the loading times can be slightly above normal, but with zero loss of quality in these normal bone xrays of the children skeleton. Due to the extreme valgus force the joint may temporarily open. If the internal epicondyle is not seen in its normal position then suspect that it is trapped within the joint. Fractures lines can be difficult to visualize after acute elbow injury, particularly in children. Are the ossification centres normal? if it does not, think supracondylar fracture.
