Fractured Ischium, Anterior View

Description

Anterior pelvic anatomy is rendered with the lumbar vertebrae descending into the sacrum and coccyx, framing the paired hip bones and acetabula with the proximal femora seated at the hip joints. On the right os coxae, the ischium is emphasized, with the fracture centered around the ischial spine on the posteromedial margin of the bone, just inferior to the greater sciatic notch and superior to the lesser sciatic notch. Medially, the pubic body and inferior pubic ramus define the anterior pelvic ring, while laterally the iliac wing and acetabular rim provide orientation to the hip. Soft-tissue and skin overlays give external landmarks without obscuring the bony injury. A clean teaching view. Fractures involving the ischial spine matter because that small projection anchors the sacrospinous ligament and sits adjacent to the pudendal nerve and internal pudendal vessels as they exit the pelvis through the greater sciatic foramen and re-enter via the lesser sciatic foramen into Alcock canal. Displacement here can explain perineal pain, neurovascular compromise, or bleeding patterns that seem out of proportion to the apparent cortical break on first inspection, and it also complicates pelvic ring stability when combined with pubic rami injuries. For operative planning, the anterior perspective helps correlate the injury with the acetabulum, obturator foramen, and the expected trajectory of fixation hardware during anterior pelvic ring approaches. Use this artwork in orthopaedic trauma and pelvic anatomy teaching to discuss pelvic fracture classification, ligamentous attachments at the ischial spine, and referred symptoms from pudendal nerve irritation. It also fits radiology and surgery texts when paired with AP pelvic radiographs or CT axial slices to orient readers to the right hemipelvis and hip joint relationship.
