(Capitellum - Radius - Internal or medial epicondyle - Trochlea - Olecranon - External or lateral epicondyle). The posterior fat pad is not visible on a normal radiograph because it is situated deep within the olecranon fossa and hidden by the overlying bone. 105 The other important fracture mechanism is extreme valgus of the elbow. There is support for both operative aswell as non-operative management of medial epicondyle fractures with 5-15mm displacement. Since these fractures are intra-articular they are prone to nonunion because the fracture is bathed in synovial fluid. 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. L = lateral epicondyle Rotation will project the metaphysis of the humerus away from a normally positioned epicondyle. Each bone,,represents an image different from the next one, but still within the same localization and age depending on the column and row they are in. On a lateral view especially if the arm is endorotated it can project so far posteriorly that one could suggest an avulsion (figure). The condition is cured by supination of the forearm.

There is enormous soft tissue swelling, which indicates that the elbow has been dislocated (blue arrows). Fracture, lateral condyle of humerus. The normal elbow already has a valgus positioning. When the forces have more effect on the humerus, the extreme valgus will result in a fracture of the lateral condyle. var sharing_js_options = {"lang":"en","counts":"1"}; If the X-ray of the elbow joint is normal, the survey report will note that its general x-ray anatomical . Dislocations of the radial head can be very obvious. They should not be mistaken for loose intra-articular bodies (arrow). It is however not uncommon that these dislocations are subtle and easily overlooked. This line is called the Anterior Humeral line . A short radius may also be the result since the epiphysis of the radius contributes to the length growth of the radius. An elbow X-ray showing a displaced supracondylar fracture in a young child . Only gold members can continue reading. Normally on a lateral view of the elbow flexed in 90? Fracture lines are sometimes barely visible (figure).

Recent research indicates an increase in the prevalence of the disease. At the end of growth, when the cartilage completely hardens into bone, the dark line will no longer be visible on an x-ray. Is there a subtle fracture? Avulsion of the medial epicondyle110 However avulsions are located more distally and anteriorly. "Keeping the arm immobilized is a key part of successful recovery," Dr. Blanco emphasizes. Lateral epicondyle. Fig. 97% followed the CRITOL order. In children however it's the radial neck that fractures because the metaphyseal bone is weak due to constant remodelling. Radius Pulled Elbow (Nursemaid's elbow) Learning Objectives. 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). A major avulsion is easy to overlook when an elbow has been transiently dislocated and then reduces spontaneously 5 , 6 because the detached epicondyle may, on the AP radiograph, be mistaken for the normally . Computed bone maturity (bone age) measurementare performed in cases of suspected growth delay or early pubertal development: Computed tomography scanogram for leg length discrepancy assessmentis performed in patients (children in most of the cases) with suspected inequality in leg length.

Treatment is usually closed reduction with either a supination or a hyperpronation technique. AP and lateral radiographs are shown in Figures A and B. Undisplaced fractures are treated with a long arm cast. Typically these fractures present with medial soft tissue swelling with pain in the condylar region. This sign relies on adequate ossification of the capitellum and therefore is reliable in children over the age of 4 years only.6(Fig 3), The radiocapitellar line evaluates the relationship of the proximal radius to the capitellum on all views (Fig 4). Elbow fat pads 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. Examination reveals that the elbow is in slight flexion and the forearm pronated but further examination is limited secondary to pain. This means that the radius is dislocated. The ossification centre for the internal (ie medial) epicondyle is the point of attachment of the forearm flexor muscles. What is the most appropriate first step in management? The anterior humeral line is drawn along the anterior cortex of the humerus and should bisect the middle third of the capitellum.

In adults fractures usually involve the articular surface of the radial head. summary. The X-ray is normal. It is important to realize that there is normally some angulation of the radial head ( up to 15?). On the medial side the valgus force can lead to avulsion of the medial epicondyle. As your child walks, runs, jumps and plays, she may topple and land the wrong way, causing a crack or break in a bone. I before T. Though the CRITOL sequence may vary slightly there is a constant: the trochlear (T) centre always ossifies after the internal epicondyle. When the ossification centres appear is not important. see full revision history and disclosures, UQ Radiology 'how to' series: MSK: Humerus and elbow. The rule to apply:On the AP radiograph a normally positioned epicondyle will be partly covered by some of the humeral metaphysis. . The hemarthros will result in a displacement of the anterior fat pad upwards and the posterior fat backwards. Acknowledgements Pediatric Elbow Trauma. . The problem with the Milch-classification is the fact that the fracture fragments are primarily cartilaginous. 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. 3% showed a slightly different order. . Your elbow bones include the upper bone of your elbow joint (humerus) and the lower bones of your elbow joint (radius and . These are the Radiocapitellar line and the Anterior humeral line. They should stay still for 2-3 seconds while each X-ray is taken so the images are clear. On the posterior side no fat pad is seen since the posterior fat is located within the deep intercondylar fossa. Medial Epicondyle avulsion (7). This article lists examples of normal imaging of the pediatric patients divided by region, modality, and age.

They occur between the ages of 4 and 10 years. AP in full extension. . This may severely damage the articular surface. Conclusions:When checking the position of the internal epicondyle on the AP radiograph: } Fractures at this point usually occur on the inside, or medial, epicondyle in children from 9 to 14 years of age. Elbow X-Rays, Don't Forget the Bubbles, 2013. . Compared to extension types, they are more likely to be unstable, so more likely to require fixation. 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. On the left we see, that the radiocapitellar line goes through centre of the capitellum on every radiogragh even though C and D are not well positioned. 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.

Proximal radial fractures can occur in the radial head or the radial neck. 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). This is normal fat located in the joint capsule. Reference article, Radiopaedia.org (Accessed on 05 Mar 2023) https://doi.org/10.53347/rID-52519.
