Sir.—Quan and Marcuse1 are not correct in stating that "There are no radiologic findings" with radial head subluxation. In the normal elbow, a line extended from the longitudinal axis of the radius bisects the humeral capitellum.2 Abnormalities in this relationship can be demonstrated in some children with radial head subluxation.2,3 If positioning for films does not happen to reduce the subluxation, alert practitioners may note positive radiologic findings.
