Pelvic Bones, Lateral View

Description

Seen in lateral profile, the male os coxae is presented with the ilium superiorly, the pubis anteroinferiorly, and the ischium forming the posteroinferior buttress of the hip bone. Centered on the lateral surface, the acetabulum is framed by the acetabular rim and notched inferiorly at the acetabular notch, with the obturator foramen opening anteroinferior to the socket between pubis and ischium. Along the posterior border, the greater sciatic notch sits superior to the ischial spine, which projects between the greater and lesser sciatic notches near the ischial tuberosity. Clear bony landmarks throughout. This lateral orientation matters because it matches the clinical “socket-side” view used to teach hip joint congruence and to discuss acetabular fractures, where the posterior wall and posterior column are common sites of injury after dashboard trauma. Posterior hip dislocation tracks with this anatomy, and the relationship of the greater sciatic notch to the posterior acetabulum provides context for sciatic nerve risk during posterior approaches to the hip. For adult male morphology, the thicker acetabular region and more robust ischial tuberosity also support sex-based comparisons in anatomy and forensic teaching. Use this asset in gross anatomy courses covering the pelvic girdle and hip joint, in orthopaedic education on acetabular fracture patterns and surgical corridors (Kocher-Langenbeck and related posterior exposures), or in radiology teaching that correlates lateral bony landmarks with oblique pelvic projections. It also suits textbook figures explaining the fused ilium, ischium, and pubis at the acetabulum and the pathways created by the sciatic notches and obturator foramen.
