In the original discription of Monteggia there is a radial dislocation in combination with a proximal ulnar shaft fracture. When the ossification centres appear is not important. Johnson KL, Bache E. In Pediatric skeletal trauma - Techniques and applications. Exactly a CT would have cost us at least a hour and the patient family good mood afforded ,i choose to do an erect chest and abdomen x-ray 1st based on history and clinical examination , the technicians here do it sometimes in one take a to save time and film because we don't have neither here , The patient was prepared and on the operating table within 40 minutes we found out he had . If part of the epicondyle is covered by part of the humeral metaphysis then an avulsion has not occurred. An elbow X-ray shows your soft tissues and elbow bones. Nerve injurie almost always results in neuropraxis that resolves in 3-4 months. 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). Radial neck fractures typically are classified as Salter Harris II fractures through the physis, and radial head fractures are intra-articular and typically occur in older children or adolescents. In those cases it is easy. In this review important signs of fractures and dislocations of the elbow will be discussed. Is the radiocapitellar line normal? On the left the anterior humeral line passes through the anterior third of the capitellum. 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. windowOpen = window.open( jQuery( this ).attr( 'href' ), 'wpcomgoogle-plus-1', 'menubar=1,resizable=1,width=480,height=550' ); But X-rays may be taken if the child does not move the arm after a reduction. CRITOL: the sequence in which the ossified centres appear. The medial epicondyle is an extra-articular structure and avulsion will not produce joint effusion.

The apophysis has undulating faintly sclerotic margins. It is however not uncommon that these dislocations are subtle and easily overlooked. Open Access . In every dislocation the first question should be 'where is the medial epicondyle'. Treatment can be nonoperative or operative depending on the degree of angulation, translation and displacement. Misleading lines114 Following treatment for an elbow fracture, most children remain in a cast for about three to four weeks. Complete blood count (CBC), prothrombin time (PT), APTT, and clotting factor tests were done to determine the clotting factors level (Table 1). (OBQ11.97) They appear and fuse to the adjacent bones at different ages. Lateral epicondyle. Especially associated fractures of the olecranon are very common (figure). The right lower image shows an obvious dislocation of the radius. R = radial head There is a fracture of the lateral humeral epiphyseal apophysis that mimics normal development in a patient 3 years older than the patient's true age. Therefore apply this rule: if the trochlear centre (T) is visible then there must be an ossified internal epicondyle (I) visible somewhere on the radiograph. This line helps you to detect a supracondylar fracture with posterior displacement (pp. If an image is blurred, the X-ray technician might take another one. The standard radiographs alkune by Tomas Jurevicius; Normal radiographs by Leonardo . if ( 'undefined' !== typeof windowOpen ) { The problem with the Milch-classification is the fact that the fracture fragments are primarily cartilaginous. Dislocations of the radial head can be very obvious. Two anatomical lines101 Supracondylar fractures (2)If there is only minimal or no displacement these fractures can be occult on radiographs. On the medial side the valgus force can lead to avulsion of the medial epicondyle. A considerable force is required to cause this fracture, and since young infants are not mobile enough to produce this force, non-accidental trauma must be suspected in these cases. Supracondylar fracture106 Wilkins KE. Exceptions to the CRITOL sequence? Diagnosis can be made clinically with a child that holds the elbow in slight flexion with pain and. I do recommend using a helmet, elbow, and knee pad the first few tries. Paediatric elbow (Table 1 and Fig 6), The medial epicondyle fuses to the shaft of the humerus at 13 years for females and 15 years for males. 80% of avulsion fractures occur in boys with a peak age in early adolescence. On the posterior side no fat pad is seen since the posterior fat is located within the deep intercondylar fossa. On some of the images you can click to get a larger view. 3% (132/4885) 5. } Notice supracondylar fracture in B. They occur between the ages of 4 and 10 years. Gradually the humeral centres ossify, enlarge, and coalesce. Occasionally a minor variation in the sequence may occur. At the time the article was last revised Jeremy Jones had no recorded disclosures. There is disagreement about the amount of displacement of the medial epicondyle that requires operative fixation.

Stabilisation is maintained with either two lateral pins or medial lateral cross pin technique. X-rays of a patient's uninjured elbow are a good indicator of normal. The mechanism is an acute valgus stress due to a fall on the outstretched hand or sometimes due to armwrestling.
