PURPOSE: To analyse the result of the treatment of ipsilateral femoral neck and shaft fractures and to consider effective method of the treatment. MATERIALS AND METHODS: Seventeen patients with ipsilateral femoral neck and shaft fractures were treated from January 1992 to January 1999 and followed up more than 2 years. Radiologic bony union between each treatment method, complication were analysed. The functional results assessed with Iowa hip rating system and Swiontkowski system. RESULTS: In femoral neck fractures, bony union was obtained in all cases, average 12 weeks. In femoral shaft fractures, bony union was obtained in all but one case. There was no statistical association bony union time between each treatment method (p>0.05). By Iowa hip rating system, nine hips had an excellent result; eight, a good result. According to rating system of Swiontkowski, the result was excellent in nine, good in six, fair in one, and poor in one. CONCLUSION: We concluded that early diagnosis of all injuries was needed. To avoid further vascular damage of femoral head, early anatomical reduction of the femoral neck fracture should be performed. And then, shaft fracture was fixed with implants which were most appropriate for that combination of fractures.
