Radial head subluxation (Nursemaid elbow)

Radial head subluxation, also known as nursemaid's elbow, is a dislocation of the elbow joint caused by a sudden pull on the extended pronated forearm, such as by an adult tugging on an uncooperative child or by swinging the child by the arms during play. The injury is most common in children between the ages of 1 and 4. Symptoms can include pain and swelling in the elbow, inability to supinate the forearm, as well as a decreased range of motion. Treatment involves a close reduction of the subluxation, and usually the prognosis is good.
