Pubis Showing The Superior Pubic Ramus, Anterior View

Description

Pubis anatomy dominates the anterior pelvis in this illustration, centering on the superior pubic ramus as it extends laterally from the body of the pubis toward the acetabulum. Medially, the pubic crest and pubic tubercle sit superior to the symphyseal surface, while the superior pubic ramus forms the anterosuperior margin of the obturator foramen inferiorly. Along its superior border, the pecten pubis (pectineal line) continues posterolaterally as the iliopectineal line, a key demarcation between the true and false pelvis and a reliable landmark for pelvic brim orientation. Bony contours are the message. Fracture patterns and surgical corridors both hinge on this segment of the pelvic ring. Superior pubic ramus fractures are common in lateral compression injuries and in osteoporotic insufficiency fractures, and their relationship to the obturator foramen helps the viewer anticipate nearby neurovascular structures, including the obturator canal at the superolateral margin of the foramen. The pubic tubercle, adjacent to the medial ramus, anchors the inguinal ligament and frames the superficial inguinal ring, which is why anterior bony landmarks matter when teaching open inguinal hernia repair, mesh placement, and the distinction between direct and indirect hernias. Surface form matters. Use this illustration in pelvic anatomy and orthopaedic trauma teaching to orient learners to the anterior pelvic ring, and in surgical education materials that reference the pectineal line (Cooper ligament) for hernia repair and pelvic brim identification. It also suits radiology primers that correlate anterior pelvic radiographs and CT pelvic ring reconstructions with named pubic landmarks.
