Automatically Assessing Limb Alignment and Hip Fracture Using 3D Models

To allow an efficient assessment of lower limb alignment and hip fracture, 3D lower limb bone models are reconstructed from patient-specific computed tomography images. The 3D feature-construction system shown here automatically extracts 3D features (centers, auxiliary points, axes, and planes). No other work exists that automatically marks all the features for the lower extremities.
