The treatment of the subtrochanteric fracture is technically very demanding, independent of the implant material used and presents a challenge in terms of surgical management. A multitude of implants based on very different biomechanical and operative concept are employed to deal with the special conditions relating to these fractuers. The purpose of this study was to analyze the results of the surgical treatment of subtrochanteric fracture using spiral blade unreamed intramedullary femoral nail. Spiral blade unreamed intramedullary nails were applied in 9 subtrochanteric fractures. Fracture healing was uneventful and implant complications or loss of reduction were not observed. In conclusion, spiral blade unreamed intramedullary nail will be a a valuable addition to the fixation techniques available for the treatment of subtrochanteric femoral fractures.
