We describe a case report where the acetabular prothesis migrated medially into the pelvis over a period of four years, following revision hip arthroplasty. This was an acute on chronic progressive displacement that caused a slow bleed from the left external iliac artery. Contrast computed tomography is the investigation of choice to diagnose such an injury and demonstrate the slow bleed as opposed to digital subtraction angiography (DSA) arteriogram.
