Which are the most common elbow fractures in adults?
Radial head and neck fractures are the most common elbow fractures in adults, which account for one-third of elbow fractures.
How usually occur the mechanism of fractures of the radial head?
The radial head fractures usually follow a fall onto an outstretched hand, with the forearm pronated and minimal or moderate flexion of the elbow, applying an axial and valgus force to the elbow.
What are the clinical manifestations of radial head fracture?
Fractures of the radial head usually occur after a fall onto an outstretched hand, and patients present with pain, swelling, and bruising at the elbow. Posterolateral dislocation of the elbow may be present. Neurological injuries affecting the median and ulnar nerves, as well as disruption to the brachial artery, may occur.
Which are the initial radiographic views in cases of elbow trauma?
The plain radiograph of the elbow joint in the anteroposterior and lateral projections is the initial method in cases of elbow trauma. If an anterior fat-pad sign due to an elbow effusion is present in the absence of any other obvious injury, proceed with a careful investigation in keeping with an occult fracture of the radial head and neck. The presence of a posterior fat pad sign is enough to presume an occult radial head fracture.
How is the diagnosis of radial head fractures made?
The radial head fracture diagnosis is at initial by radiography, with subtle radial head fractures indicated by elevation of the anterior and posterior fat pads, which correspond to joint effusion.

No other fracture was detected. The alignment of the elbow is intact.
Impression: Non-displaced intra-articular fracture of the radial head, consistent with a Mason type I fracture.
