A Posterior View Of The Head Of The Femur

Description

Rotating into a posterior view, the animation centers on the femoral head (caput femoris) and tracks its smooth, spherical articular surface as it blends inferiorly and laterally into the femoral neck (collum femoris). The fovea capitis is visible as a small posteromedial depression on the head, a landmark that contrasts with the surrounding hyaline cartilage covered surface. As the sequence progresses, the head–neck junction becomes clearer and the posterior contour of the proximal femur reads as a continuous curve rather than a flat profile. Posterior femoral head anatomy matters when you are teaching why the hip is both stable and vulnerable: the head’s cartilage covered surface must remain congruent with the acetabulum during flexion, extension, and rotation, while the head–neck offset influences femoroacetabular impingement patterns. The fovea capitis is also a practical orientation point when discussing the ligament of the head of femur (ligamentum capitis femoris) and its small vascular contribution, a topic that comes up in femoral neck fractures and avascular necrosis risk. Motion helps here, since the changing specular highlight across the articular surface makes curvature, sphericity, and the head-to-neck transition easier to judge than in a single frame. Use this posterior hip bone animation in gross anatomy labs, orthopedic teaching on intracapsular femoral neck fractures and hip arthroscopy landmarks, or as a figure asset for radiology correlation when explaining how head–neck morphology relates to cam-type impingement on axial MR and CT reconstructions.
