We develop 3D automatic feature construction system to efficiently quantify different types of the lower limb alignment and the hip fracture. This system has the potential to provide useful information regarding the risk of knee and hip osteoarthritis, and should be considered an alternative method for the measurement of the lower limb alignment and the hip fracture. Our newly defined parameters (hip-knee-ankle, condylar-hip, plateau-ankle, condylar-plateau, condylar-tibia angles and mechanical axis deviation) completely exhibit the lower limb alignment and are coincident with the physicians' diagnosis. Neck-shaft angle measured for the hip fracture is also coincident with physicians' knowledge. Our novel quantitative and visual assessments of these parameters demonstrate that the automatic system can obviously improve the performance of the lower limb alignment assessment and the hip fracture diagnosis.
