Radial head dislocation occurs when the radial head is displaced from its normal articulation with the ulna and the humerus. The dislocation may be acquired or congenital (see the separate article on congenital radial head dislocation). Additionally, radial head dislocation should be distinguis...

Pulled elbow (also known as nursemaid's elbow) is a subluxation of the radial head into the annular ligament, which usually spontaneously or easily reduces and rarely demonstrates abnormal radiographic features. If the clinical presentation is atypical, pulled elbow should be distinguished from ...

The elbow is a complex synovial joint formed by the articulations of the humerus, the radius, and the ulna.  Gross anatomy Articulations The elbow joint is made up of three articulations 2,3: radiohumeral: capitellum of the humerus with the radial head ulnohumeral: trochlea of the humerus w...

Flexion supracondylar humeral fractures account for only 2-4% of all supracondylar fractures 1. Epidemiology Unlike the much more common extension supracondylar fracture which are seen in children, flexion fractures are seen in older (adult) patients. Pathology They are usually the result of...

Epicondyle fractures are common injuries in children. They represent 10% of all elbow fractures in children and usually occur in boys after a fall on an outstretched arm. Medial epicondyle fractures comprise most of these injuries. They can usually be treated with splinting and early physiother...

The anterior humeral line is key to demonstrating normal elbow alignment and should be used whenever reading a pediatric elbow radiograph to exclude a subtle supracondylar fracture. Measurement A line drawn down the anterior surface of the humerus should intersect the middle third of the capit...

The radiocapitellar line is one of the key lines used to assess alignment on the elbow radiograph. It is particularly useful in the pediatric setting. Measurement A line drawn down the neck of the radius should intersect the capitellum. It is important to ensure that you draw the line down the...
