Hip joint modeling for the control of the joint center and the range of motions

Kang, M. and Sadri, H. and Moccozet, L. and Magnenat-Thalmann, N.


Abstract: This paper presents a medical visualization tool implementing a hip joint modeling method that offers the control of the hip joint center and the assessment of the hip range of motions. As the shape of the femoral head is not a perfect sphere, it is in fact close to a 3D conchoid shape, the resulting articulation center cannot be modeled as the center of the sphere that best approximates the femoral head. In order to correctly assess the range of motion of a patient’s hip, the medical doctor cannot proceed with such an approximation method. An automatic computation methodology of the hip joint center location is being designed and implemented based on the shape of the acetabular rim. And more, the extreme ranges of motions are calculated on the bony hip model.
