<unk>  is a dislocation of the elbow joint caused by a sudden pull on the extended pronated arm, such as by an adult tugging on an uncooperative child.
In radial head subluxation, there is little complaint of pain, and the patient generally reports pain in the distal forearm. Radial head subluxation is a common pediatric presentation generally occurring between the ages of 1 and 3 years. The mean age of presentation is just older than 2 years.
The pathologic lesion is generally a tear in the attachment of the annular ligament to the periosteum of the radial neck, with the detached portion becoming trapped between the head of the radius and the capitellum.
The older child will usually point to the dorsal aspect of the distal forearm when asked where it hurts. This may mislead one to suspect a buckle fracture of the distal radius.
