Gap nonunion of forearm bones treated by modified Nicoll’s technique

The management of an atrophic nonunion with a gap following a fracture of the radius and/or ulna is a challenging problem. Various methods of treatment available in the literature are cortical tibial graft (Boyd), ulnar segment graft (Miller and Phalen), iliac crest graft (Spira), cancellous insert graft (Nicoll), vascularized fibular graft (Jupiter), and bone transport by ring fixator (Tesworth). The present study reports the results of tricorticocancellous bone block grafts using modified Nicoll's technique, in diaphyseal defects of forearm bones.
