The diaphyseal aseptic tibial nonunions after failed previous treatment options managed with the reamed intramedullary locking nail.

In conclusion, a reamed intramedullary nail provides optimal conditions for stable fixation, good rotational control, adequate alignment, early weight-bearing and a high union rate of tibial non-unions. Reaming of the medullary canal with preservation of periosteal sleeve create the "breeding ground" for sound healing of tibial shaft nonunions. Additionally cancellous bone grafting is recommended only in the case of defect nonunion.
