From: Biomechanical study of isolated radial head dislocation
Incidence of radial head dislocation. According to ligament sectioning, the incidence of radial head dislocation increased. Radial head began to dislocate laterally after annular ligament sectioned. And next, posterior radial head dislocation was observed after quadrate ligament sectioned especially in neutral position. Anterior radial head dislocation was occurred after proximal half of IOM sectioned
