Elbow X-Rays, Don't Forget the Bubbles, 2013. . 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.

Bilateral hemotympanum as a result of spontaneous epistaxis. The rule to apply:On the AP radiograph a normally positioned epicondyle will be partly covered by some of the humeral metaphysis. The other important fracture mechanism is extreme valgus of the elbow. Fracture, lateral condyle of humerus. A child with nursemaid's elbow will not want to use the injured arm because moving it is painful. They are extrasynovial but intracapsular. Recent research indicates an increase in the prevalence of the disease. On reducing the elbow the fragment may return to it's original position or remain trapped in the joint. Lateral condyle fractures are classified according to Milch. These fractures require closed reduction and some need percutaneous fixation if a long-arm cast does not adequately hold the reduction. tilt closed reduction is performed. olecranon. [CDATA[ */ Conclusions On the left the anterior humeral line passes through the anterior third of the capitellum. Vigorous muscle contraction may avulse this centre (see p. 105). In theory, X-rays are allowed to make children over 14 years old. HOPEFULLY THE OLD MAN CAN STILL TEACH THE KID A FEW THINGS. Misleading lines114 tilt of the radial head patients are treated with a collar. Positive fat pad sign (2)Any elbow joint distention either hemorrhagic, inflammatory or traumatic gives rise to a positive fat pad sign. This is normal fat located in the joint capsule. On the medial side the valgus force can lead to avulsion of the medial epicondyle. When the forces have more effect on the humerus, the extreme valgus will result in a fracture of the lateral condyle. The multiple ossification centers may be difficult to differentiate from fractures in the acute traumatic setting. . In children dislocations are frequent and can be very subtle. Unable to process the form. It generally occurs in children between the ages of 1 and 4 years old, though it can happen up to 7 years old. They will hold the arm straight or with a slight bend in the elbow. In every dislocation the first question should be 'where is the medial epicondyle'. see full revision history and disclosures, Computed bone maturity (bone age) assessment, Computed tomography scanogram for leg length discrepancy assessment, normal-pediatric- hip-ultrasound-graf-type-i, Computed bone maturity (bone age) measurement, Integral Diagnostics, Shareholder (ongoing). However fractures anywhere along the ulna have been reported. If the internal epicondyle is not seen in its normal position then suspect that it is trapped within the joint. It is not important to know these ages, but as a general guide you could remember 1-3-5-7-9-11 years. summary. Since the medial epicondyle is an extra-articular structure a fracture or avulsion will not automatically produce a positive fat pad sign. Unable to process the form. A 2011 survey4 of 500 paediatric elbow radiographs found: But: there were no instances in which the trochlear ossification centre appeared before the medial (internal) epicondylar centre. If part of the epicondyle is covered by part of the humeral metaphysis then an avulsion has not occurred. Usually there is some displacement and the anterior humeral line will not pass through the centre of the capitellum but through the anterior third or even anterior to the capitellum (figure). However, obtaining bilateral films should used selectively, not routinely. Look especially for the position of the radial epiphysis and the medial epicondyle (figure). That being said, it can also occur due to birth trauma- both vaginal delivery and cesarean section. In this review important signs of fractures and dislocations of the elbow will be discussed.

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. (2017) Orthopedic reviews. A fracture should be splinted in a position of function until outpatient orthopedic follow-up is available. Overprojection of the capitellum on the humeral metaphysis may simulate a lateral condyle fracture (figure). The medial epicondyle is seen entrapped within the joint (red arrows). The rotation of the fracture fragment gives a typical appearance on the X-rays (arrow).

The elbow becomes locked in hyperextension. Is the piece of bone that you're looking at a normal ossification centre and is this ossification centre in the normal position. On the left a couple of examples of lateral condyle fractures. Notice supracondylar fracture in B. The medial epicondyle is an extra-articular structure and avulsion will not produce joint effusion. The fracture fragment is often rotated. They concluded that in trauma displacement of the posterior fat pad is virtually pathognomonic of the presence of a fracture.

However avulsions are located more distally and anteriorly. Illustration of the pediatric elbow describing the normal appearance of the secondary ossification centers. In cases of a supracondylar fracture the anterior humeral line usually passes through the anterior third The fracture line through the cartilage is not visible on radiographs, so the radiographic interpretation concerning classification is difficult.
