A Medial View Of The Hip Bone Showing The Location Of The Obturator Groove

Description

Rotating on a medial perspective of the os coxae, the animation brings the pubis into clear relief and tracks along the superior pubic ramus to the obturator groove (sulcus obturatorius). The shallow channel is shown immediately inferior to the pecten pubis (pectineal line) and forms the superior margin of the obturator foramen, with the iliopubic eminence sitting superolaterally at the junction of ilium and pubis. As the camera angle subtly shifts, the groove’s relationship to the obturator crest and to the medial surface of the pelvis becomes easier to judge. Orientation stays grounded in anatomical position. That spatial context matters because the obturator groove contributes to the obturator canal when bridged by the obturator membrane, creating the passageway for the obturator nerve, artery, and vein from the pelvic cavity to the medial thigh. A small, rigid canal at the superior edge of the obturator foramen is a predictable site of entrapment in obturator hernia, and it is a key landmark when teaching pain referral patterns to the medial thigh and gait changes from obturator neuropathy. Motion helps here: seeing the groove traced along the superior pubic ramus clarifies why the neurovascular bundle hugs the bony margin rather than crossing the obturator foramen freely. Use this animation in gross anatomy labs to cue students during pelvic osteology practicals, and in nursing or medical curricula when linking pelvic bony landmarks to obturator canal contents. It also supports figure development for orthopedic and general surgery texts discussing obturator hernia, pelvic ring anatomy, and approaches that require respect for the obturator vessels along the superior pubic ramus.
