Compared to extension types, they are more likely to be unstable, so more likely to require fixation. CRITOL: Capitellum, Radial head, Internal epicondyle, Trochlea, Olecranon, Lateral epicondyle. On a true lateral radiograph, the normal anterior fat pad is seen as a radiolucent line parallel to the anterior humeral cortex; and the posterior fat pad is invisible. Steps: Hourglass sign/figure of eighty Anterior fat pad evaluation Posterior fat pad evaluation Anterior Humeral line . It is strictly prohibited to use our medical images without our permission. So the next question is where is the medial epicondyle? The multiple ossification centers may be difficult to differentiate from fractures in the acute traumatic setting. 103 On the medial side the valgus force can lead to avulsion of the medial epicondyle. Occasionally a minor variation in the sequence may occur. Olecranon fractures occur in children from a direct blow to the elbow or from a FOOSH. 1. 104 Treatment strategies are therefore based on the amount of displacement (see Table).

We use cookies to ensure that we give you the best experience on our website. A major avulsion is easy to overlook when an elbow has been transiently dislocated and then reduces spontaneously5,6 because the detached epicondyle may, on the AP radiograph, be mistaken for the normally positioned trochlear ossification centre (p. 105). Since these fractures are intra-articular they are prone to nonunion because the fracture is bathed in synovial fluid. Bali Medical Journal, 2018.

Stabilisation is maintained with either two lateral pins or medial lateral cross pin technique. On the AP radiograph a normally positioned epicondyle will be partly covered by some of the humeral metaphysis. Fracture, lateral condyle of humerus. The avulsed medial epicondyl was found within the joint and repositioned and fixated with K-wires. Why is the pediatric elbow difficult?The challenge comes from the complex developmental anatomy with multiple ossification centers that mature at different ages. A short radius may also be the result since the epiphysis of the radius contributes to the length growth of the radius. Ensure adequate filmsAn AP film should be obtained with the elbow in full extension and the forearm supinated (Fig 1). Normal alignment. Gradually the humeral centres ossify, enlarge, and coalesce. 9 Patients usually present with lateral elbow pain after a FOOSH with the forearm in supination, creating a varus force on the elbow. /*
