[Subluxation of the radial head].
It is our impression that subluxation of the caput radii is a little known injury, especially in general practice. This article presents a review of the literature. Subluxation of the caput radii is a common injury among toddlers. The yearly incidence is approximately 1% among children under five years of age, with peak incidence around two years. It affects the left elbow more frequently than the right and girls more frequently than boys. Pull of the affected arm as mechanism of injury, decreased arm movement and absence of local swelling is typical for this condition. Radiographic abnormalities are very subtle or non-existent. Reduction can usually be obtained by supination of the affected arm. After successful reduction, normal function of the arm is regained within 15 minutes in most instances. In cases with typical mechanism of injury and typical clinical findings, reduction can be performed without X-rays. However, it should be checked that spontaneous and normal use of the affected arm is obtained after reduction.
