    MethodsThe clinical results after DFN-osteosynthesis of n = 56 AO-classification 33A-fractures (32%), 33C-fractures (43%), 32X-fractures (21%) and treatment of non-union (4%) are presented.ResultsFollow-up was available for 54 fractures (96%) after a mean of 1.2 years (range 0.2-2.8 years). 95% of patients showed full-weight-bearing with a knee flexion of 120 (60-140) degrees. Extension-deficit > 10 degrees was observed in 5.4%. All fractures were consolidated. One soft-tissue infection, one partial loss of reduction and one implant failure were observed. A significant axial malalignment was found radiologically in 17%, a loosened spiralblade or locking screw in 7.4%. In 91% of cases the result was judged as good to excellent by patients.ConclusionThe mechanical stability of the implant allows a save osteosynthesis of unstable supracondylar and complete articular femoral fractures without additional bone grafting. Mechanical stability and minimal invasive operative technique permit a safe bone healing without major complications.
