description abstractThis paper presented a new method of shape analysis of hip joint. The bony surfaces of 12 male hipbone specimens and 26 female hipbone specimens were scanned using a 3D laser scanner. After performing local and global morphology analyses on the acetabulum surface, a rotation ellipsoid CAD model was applied to fit the acetabulum surface, and then an optimization technique was used to find the geometric parameters of the model. This study compared the fitting error between the sphere and rotation ellipsoid. The result is that the fitting error of rotation ellipsoid is smaller than the sphere, and the rotation ellipsoid can describe the shape of the acetabulum better. This shape likely decreases the cases of hip joint subluxation compared to a ball and socket joint.
