Complete blood count (CBC), prothrombin time (PT), APTT, and clotting factor tests were done to determine the clotting factors level (Table 1). supracondylar fracture). In the older child, these fractures are due to a direct blow to the lateral epicondylar region and are usually associated with other injuries of the elbow. Elbow fat pads97 On the posterior side no fat pad is seen since the posterior fat is located within the deep intercondylar fossa. older than 2.5 years old due to the small size. A site with detailed information on fractures and therapy. When a major displacement of the internal epicondyle occurs the bone can become trapped within the elbow joint.

CRITOE is a mnemonic for the sequence of ossification center appearance. So, if you see the ossified T before the I then the internal epicondyle has almost certainly been avulsed and is lying within the joint ie it is masquerading as the trochlear ossification centre (see p. 105). It might be too small for older young adults. Skeletal surveys are performed in cases of: suspected non-accidental pediatric skeletal injury, post-mortem before an autopsy in cases of suspected sudden infant death syndrome (SIDS) to exclude traumatic skeletal injury or skeletal abnormalities indicative of an underlying naturally occurring disease.

The diagnosis can be challenging since the distal humeral epiphysis is cartilaginous and not visualized on x-rays. Look for a posterior fat pad. Bilateral hemotympanum as a result of spontaneous epistaxis. In the original discription of Monteggia there is a radial dislocation in combination with a proximal ulnar shaft fracture. 102 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. 1.
