Figure 2 Illustration of three-dimensional pelvic reconstruction in a male patient. A: Mid-sagittal lateral view: (AB) anterior-posterior diameter of pelvic inlet, (CD) anterior-posterior diameter of mid-pelvis, (CE) anterior-posterior diameter of pelvic outlet, (AC) superior-inferior diameter of the pubic symphysis, (BE) sacrococcygeal distance, (BD) superior-inferior diameter of sacrum, (AE) superior pubococcygeal diameter, (FG) anterior-posterior sacropubic distance, (FI) sacrococcygeal curvature height, (FH) sacral curvature height, (α) sacrococcygeal angle, (β) sacropubic angle; B: Anteroposterior view: (PQ) transverse diameter of pelvic inlet and (LM) interischial spine diameter; C: Posteroanterior view: (LM) interischial spine diameter and (NO) interischial tuberosity diameter.
