Bipolar dislocation injury of the forearm is rarely documented. It is a combined forearm injury with trauma on the elbow side and on the side of the wrist joint. We describe two different cases of this complex dislocation. The first patient suffered from a Monteggia-like dislocation fracture with transscaphoid dislocation of the wrist. The second person had an acute longitudinal radioulnar membrane dissociation after elbow dislocation with an additional scapholunate tendon rupture. The difficult management of these injuries is illustrated by these cases.
