Idiopathic subluxation of the radial head.
Idiopathic subluxation of the radial head is a different entity from congenital dislocation. The former is always painful, with marked loss of rotation. The radius articulates with the capitellum and the radial head is concave, possibly representing a lesser stage of dislocation. There also may be a correlation with true posterior dislocation. Since it successfully alleviates pain in this condition, radial head resection is often advisable. However, the operation should be delayed until growth is complete and the danger of disruption of the distal radioulnar joint is avoidable.
