Fractured Sacrum, Anterior View

Description

Frontal anatomy centers on the pelvic (anterior) surface of the male sacrum, with the sacral promontory forming the superior margin at the lumbosacral junction and the broad sacral alae flaring laterally toward the auricular surfaces for the sacroiliac joints. A right-sided fracture line traverses the sacral body toward the ala, interrupting the smooth concavity of the pelvic surface adjacent to the anterior sacral foramina. Inferiorly, the injury approaches the apex of the sacrum where it would normally articulate with the coccyx, while portions of the lower lumbar vertebrae and adjoining hip bones provide midline and lateral orientation. Anterior sacral fractures matter because the pelvic surface lies immediately posterior to the presacral space, where hemorrhage can track and where the lumbosacral trunk and superior hypogastric plexus run close to bone. Disruption near the anterior sacral foramina raises concern for sacral nerve root involvement, a pattern often discussed with Denis zone fractures and with unstable pelvic ring injuries after high-energy trauma. This perspective also helps correlate CT findings with potential anterior pelvic organ and neurovascular risk, distinct from the posterior elements and spinous landmarks emphasized in dorsal views. A high-stakes region. Use this artwork for teaching pelvic ring mechanics in orthopedic trauma modules, illustrating sacral fracture patterns in radiology or emergency medicine texts, or supporting patient-facing education on lumbosacral and sacroiliac injury. It also fits operative planning discussions comparing iliosacral screw trajectories to anterior corridor hazards, where an anterior reference view clarifies what is at risk beyond the cortex.
