APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -The two bones meet in the midline at the pubic symphysis. The two inferior rami at the lower border of pubic symphysis subtend the subpubic angle. In females the subpubic angle is more than 90° and in males it is less than 90°.

Detailed explanation-2: -Among 332 pelvic radiographs studied, the mean subpubic angle was found to be 120.42±22.27° (118.02-122.81 at 95% Confidence Interval). The subpubic angle in females was 137.96±12.47° and that in males was 101.10±12.56°.

Detailed explanation-3: -sub·pu·bic angle ˌsəb-ˈpyü-bik-: the angle that is formed just below the pubic symphysis by the meeting of the inferior ramus of the pubis on one side with the corresponding part on the other side and that is usually less than 90° in the male and usually more than 90° in the female.

Detailed explanation-4: -For measuring subpubic angle, two tangent lines were drawn along the inferior border of the pubic rami. The angle made through the intersection of these two lines represents the subpubic angle.
