Abstract:

BACKGROUND: Prostheses designed for Western is not very suitable for Chinese proximal femur.
OBJECTIVE: To provide reference for prosthesis design for Chinese based on the dimensions of proximal femur measured from CT films.
METHODS: The dimensions were measured at the neck, lesser trochanter and isthmus of the femur from 61 patients by CT films.
RESULTS AND CONCLUSION: There was a correlation among the three dimensions of the femoral isthmus, between wide-dimension and medial-dimension of the femoral neck, and between long-dimension and medial-dimension of the lesser trochanter of the femur (P < 0.05). There was a difference between men and women in wide-dimension, long-dimension, medial-dimension of the femoral neck and cortical thickness of the femoral isthmus. Measurement data of the proximal femur could provide reference for prosthesis design.
