Clinical trial of the distal femur nail

摘要

abstract_textpMethod. The clinical results after DFN-osteosynthesis of n=56 AO-classification 33A-fractures (32),33C-fractures (43),32X-fractures (21) and pseudarthrosis treatment (4) are presented./ppResults. Follow up was available for 54 fractures (96) after a mean of 1.2 years (range 0.2-2.8 years). 95 of patients showed fullweight-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 and surgeons./ppConclusion. The 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./p/abstract_text
