Retrograde Nailing of Distal Femoral Fracture – Clear and Potential Indications
- 82 Downloads
Despite the fact that fracture treatment of the supracondylar region of the femur is known to be a therapeutic challenge, a high incidence of complications was reported with extramedullary osteosynthesis. New techniques of biological osteosynthesis and specific implants have been developed to improve treatment of supra- and diacondylar fractures of the femur. In the present series, we report on various clear indications for the use of the distal femur nail (DFN). Moreover, some potential indications for the DFN are presented and their advantages discussed. Clinical evaluation demonstrated that 92% of the fractures treated with the DFN healed without bone grafting, and the clinical results were excellent or satisfactory according to the criteria of Neer et al. Failure of the technique or infection was not observed. Based on our results, we feel that retrograde nailing of the femur, either with percutaneous or open techniques, is a suitable addition to the established techniques of osteosynthesis of the distal femur.
