Isolated and combined fractures of the diaphysis of the radius and ulna.

In summary, treatment of diaphyseal fractures requires accurate assessment of the injury to rule out concomitant ligamentous injury at the wrist or the elbow. Minimally displaced ulnar fractures can be managed with bracing. Displaced diaphyseal fractures of the radius and ulna should be plated, usually with 3.5-mm compression plates using AO technique. Complications may still occur but can be minimized if strict attention to technique is followed.
