Isolated radial head dislocation, a rare and easily missed injury in the presence of major distracting injuries: a case report

Abstract: High velocity accidents can lead to major injuries -long bone fractures, abdominal trauma, pelvic fractures and chest injuries. These injuries can act as distracting factors during the initial assessment of a polytrauma patient and innocuous but significant smaller injuries can be missed. We present a rare case of isolated anterolateral radial head dislocation in a polytrauma patient.

“…However, radial head dislocation without any bone injury has been reported in both children 2,8,22 and adults. 3,4,14,18,20 The specific purpose of this study was to determine the contributions of the annular ligament and the proximal, central, and distal bands of the interosseous membrane of the forearm in preventing transverse dislocation of the radius. We hypothesized that the proximal band, annular ligament, and central band provide support when transverse forces are applied to the forearm, such as when biceps muscle activation occurs.…”

“…También se ha propuesto que un posible mecanismo de lesión sea mediante una fuerza aplicada con el miembro en hiperextensión y pronación. 8,9 U n a v e z p r o d u c i d a l a l u x a c i ó n , l a incapacidad de reducción cerrada puede deberse, principalmente, a dos mecanismos: el primero está dado por incompetencia del ligamento anular lesionado para mantener la cúpula radial en posición anatómica. El segundo es el resultante de la interposición de partes blandas.…”
