Fig. 5

Progression of the intersections in the medial side of the humerus. The value of the horizontal axis represented the percentage which was calculated by the value of the z axis of the intersection divided by the radius of the medial aspect. The value of the longitudinal axis represented the percentage which was calculated by the value of the y axis of the intersection divided by the radius of the medial aspect. The original point was the projection of the center of the medial aspect humerus. The orange dots in the figure were the intersections between the rotation axis of the ulnohumeral joint and the medial aspect of the humerus. The blue dotted line represented the trend of the intersections from anterior-inferior to posterior-superior with the increment of the elbow flexion
