Body Of The Ilium Displayed, Lateral View

Description

Ilium body anatomy dominates the superolateral acetabular region in this lateral image of the coxal bone. The iliac contribution to the acetabulum forms the superior rim and adjacent lunate surface, lying superior to the acetabular notch and lateral to the pelvic brim, with the gluteal (external) surface facing the viewer. Anteriorly, the anterior inferior iliac spine sits superior to the acetabular margin, while posteriorly the posterior inferior iliac spine and the superior border of the greater sciatic notch frame the posterior acetabular column. Orientation is unambiguous. Orthopaedic planning often hinges on the exact bony contour where the ilium meets the acetabulum, because fractures traversing the anterior or posterior columns can propagate through the iliac body and disrupt the hip socket’s superior weight-bearing dome. Pelvic osteotomies (for example, periacetabular osteotomy) also reference this bone stock to reorient acetabular coverage in developmental dysplasia of the hip, and the lateral perspective helps communicate how the outer ilium supports the acetabular roof relative to the ASIS/AIIS landmarks without the visual noise of the sacrum or pubis. Subtle curvature changes along the acetabular rim read cleanly under directional lighting, which supports accurate annotation of the supracetabular region used in acetabular component placement and screw trajectory discussions. Use this illustration in pelvic girdle anatomy teaching, hip and acetabular fracture chapters, surgical approach overviews (ilioinguinal and Kocher-Langenbeck correlations), and radiology education when pairing with Judet views or CT-based column concepts.
