Lateral View Of Acetabular Margin Of The Hip Bone

Description

Rotating through a lateral perspective of the os coxae, the animation centers on the acetabular margin, the circumferential bony lip that bounds the lunate articular surface and frames the acetabular fossa. Superiorly, the acetabulum aligns with the iliac body; anteroinferiorly it approaches the pubic body; posteroinferiorly it blends into the ischial body, with the acetabular notch interrupting the rim inferiorly. As the hip bone turns, the relationship of the rim to adjacent landmarks becomes clear, including the anterior inferior iliac spine anterior and superior to the socket and the greater sciatic notch posterior and superior. Rim geometry matters. Clinically, the acetabular margin is where the acetabular labrum attaches and where rim morphology contributes to femoroacetabular impingement (cam and pincer patterns), labral tearing, and early chondral damage on the anterosuperior quadrant. A moving lateral view helps you appreciate how subtle overcoverage or focal prominence at the anterior or superolateral rim projects in space, which correlates with findings on AP pelvis and false-profile radiographs and guides acetabular rim trimming or labral repair planning. The sequence also clarifies why the inferior acetabular notch is a consistent interruption of the rim, a landmark during open and arthroscopic approaches. Use this animation for pelvis and hip modules in gross anatomy, orthopaedics teaching on FAI and acetabular dysplasia, and medical publishing figures that need clean rim-focused orientation without distraction from the femoral head. It also fits preoperative education assets for hip arthroscopy and periacetabular osteotomy discussions where rim location and quadrant terminology must be unambiguous.
