- Purpose
This study analyzed the morphological features of the contralateral femur without an atypical fracture by constructing a three-dimensional model with an actual size medullary canal.
Materials and Methods
Lateral and anterior bowing of the shaft were measured for 21 models, and the shape of the medullary canal was analyzed. To eliminate the projection error, the anteroposterior (AP) femur was rotated internally to the extent that the centerline of the head and neck, which is the ideal position of cephalomedullary nail screw, was neutral, and the lateral femur matched the medial and lateral condyle exactly.
Results
The lateral bowing and anterior bowing was an average of 5.5° (range, 2.8°-10.7°; standard deviation [SD], 2.4°) and 13.1° (range, 6.2°-21.4°; SD, 3.2°), respectively. In the area where lateral bowing increased, the lateral cortex became thicker, and the medullary canal was straightened. On the lateral femur, the anterior angle was increased significantly, and the diameter of curvature averaged 1,370.2 mm (range, 896-1,996 mm; SD, 249.5 mm).
Conclusion
Even if the anterolateral bowing increases in the atypical femur, the medullary canal tends to be straightened in the AP direction. So, it might be considered as a reference to the modification of an intramedullary nail to increase the conformity.

Abstract
PDF
- Atypical fractures associated with prolonged bisphosphonate (BP) therapy rarely occur outside the femur, and the diagnostic criteria, appropriate treatment principles, and fixation methods for atypical ulnar fractures have not been established. The authors experienced the use of internal fixation with a metal plate and a new internal fixation method with an intramedullary nail in the treatment of an atypical ulnar fracture in a patient who had been on BP therapy for 10 to 20 years. This paper reports findings along with a review of the relevant literature.
