Abstract:
Objective:To obtain 29 anatomic parameters of normal Chinese proximal femur through CT 3D reconstruction so as to provide anatomical references for hip prosthesis selection and design. Methods:Bilateral proximal femurs of 82 normal Chinese were scanned by CT and visualized by CT 3D reconstruction. The parameters of proximal femur were measured by medical imaging analysis software and compared with the existing references. Results: The shape and size of proximal femoral medullary cavity had obvious individual diversities. All morphologic parameters of the proximal femur was close to a normal distribution with no marked difference between left and right side. Neck shaft angle was negatively correlated with offset; the femoral head diameter had a strong correlation with femoral neck diameter, femoral head height, distance between femoral head tip to great trochanter, and distance between apex of femur anterior arch to less trochanter section. The offset and neck-shaft angle were significantly different between Chinese and Caucasian(P
