Small differences between anatomical and mechanical sagittal femur axes: a radiological and navigated study of 50 patients.
The purposes of the study were to define the orientation of the anatomical and mechanical axes of the femur on the lateral plane on long leg X-rays including the femoral head, and to compare these results to the intra-operative measurement of the mechanical axis by a nonimage-based navigation system. ⋯ The differences observed are small and have probably little clinical relevance. The distal cortical axis may be the best compromise. The navigation system allows measuring accurately the orientation of the distal femoral resection in the sagittal plane.
