The lateral and medial margins of the shaft are concave, with the medial margin possessing the greatest degree of curvature and the shortest length. The distal extremity of the pubic plate shows a straight margin medially (i.e. the pubic symphysis) and a convex one ventrolaterally, with a gradual transition between the two. Medially, the concave margin of the shaft and the straight one of the pubic symphysis meet at an angle of approximately 90°, and form a pointed peak. Laterally, the shaft gradually transforms into the pubic plate with an undulation of small intensity. The rugged area marking the existence of cartilage
