[Percutaneous minimal invasive autologous spongiosa transplantation]

In eight patients with delayed union or nonunion after 3 degrees open fracture of the tibia, a minimally invasive technique of autologous bone grafting was performed. Bone harvesting from the iliac crest and debridement of the fracture side were done percutaneous by using a 5.5 mm acromionizer without complications. In seven of eight patients complete fracture healing could be achieved (88%). Percutaneous autologous bone grafting can be recommended on limited bone defects in patients with nonunion or delayed union of the tibia and severe soft tissue damage in the lower leg.
