Aim. To evaluate whether aseptic hypertrophic nonunion in the long bones of the lower extremity can be treated successfully with LISS applied with closed methods without grafting. Materials and Methods. The study included 7 tibias and 9 femurs of 16 patients. All cases had hypertrophic nonunion. Initial surgical treatment was with intramedullary nailing in 14 cases, 6 of which had required an exchange of intramedullary nail. All the patients were treated with LISS plate with closed methods. Results. Union was obtained at mean 7 months in all patients. No implant loosening or breakage of the implant was observed and there was no requirement for secondary surgery. Conclusion. Cases of hypertrophic nonunion have excellent blood supply and biological potential. Therefore, there is no need for bone grafting and the addition of fracture stability is enough to achieve full union. Using a limited approach and percutaneous screw insertion, LISS provides fracture stabilization with soft tissue protection.
