Management of Forearm Nonunion

Forearm nonunion is rare but a possible complication after standard treatment of the fracture of radius and ulna. The importance of precise restoration of length and anatomical relationship of both bones are among usual concerns. The situation is more complex when the infection is present in the union site. The several techniques have been applied to manage forearm nonunion consisting of osteosynthesis and using cancellous autograft, allograft, nonvascularized fibular graft, fibular flap, bone transport, induced membrane (Masquelet technique), and pedicled flap such as posterior interosseous and radial forearm bone flap (RFBF). Reviewing the recent studies focusing on treating forearm nonunion is the purpose of this review.
