As I and new colleagues constantly had to look up different ossification centers and compare with the present children bone xray at the time I found having a little library of bone xrays available was very helpful. There are three findings, that you should comment on. AP view; lateral view96 Most are Milch II fractures that travel from the lateral humeral metaphysis above the epiphysis and exit through the lateral crista of the trochlea leading to an unstable humeral ulnar articulation. They are not seen on the AP view. The medial epicondyle is seen entrapped within the joint (red arrows). When the ossification centres appear is not important. . The apophysis has undulating faintly sclerotic margins. This is a repository of example radiographs (x-rays) of the pediatric skeleton by age. There are 6 ossification centres around the elbow joint. Radiographic assessment of acute pediatric elbow trauma requires a firm grasp of developmental anatomy, radiographic landmarks, and common injury patterns. They are not seen on the AP view. Ulnar nerve injury is more common. The fracture line through the cartilage is not visible on radiographs, so the radiographic interpretation concerning classification is difficult. First study the images on the left. These fractures occur when a varus force is applied to the extended elbow. Before reading this article you can try one of the cases in the menubar.

For a true lateral view the shoulder should be at the level of the elbow. 104 Because of the valgus position of the normal elbow an avulsion of the lateral epicondyle will be uncommon. AP and lateral: the CRITOL sequence Canine elbow dysplasia (ED) is a condition involving multiple developmental abnormalities of the elbow joint. 102 CRITOL is a really helpful tool when analysing a childs injured elbow. Since the medial epicondyle is an extra-articular structure a fracture or avulsion will not automatically produce a positive fat pad sign.

It was inspired by a similar project on . Radiocapitellar lineA line drawn through the centre of the radial neck should pass throught the centre of the capitellum, whatever the positioning of the patient, since the radius articulates with the capitellum (figure). Nerve injurie almost always results in neuropraxis that resolves in 3-4 months. Look especially for the position of the radial epiphysis and the medial epicondyle (figure). Are the fat pads normal? I before T. Though the CRITOL sequence may vary slightly there is a constant: the trochlear (T) centre always ossifies after the internal epicondyle.

At birth the ends of the radius, ulna and humerus are lumps of cartilage, and not visible on a radiograph. 1. 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. Lateral Condyle fractures (5) In lateral condyle fractures the actual fracture line can be very subtle since the metaphyseal flake of bone may be minor. Sometimes this happens during positioning for a . However, obtaining bilateral films should used selectively, not routinely. 9 (1): 7030.
