Anterior cup edge and iliopsoas tendon assessment on hip arthroplasty MRI

In hip arthroplasty MRI, reduced anteversion of the acetabular cup exposes the anterior edge, leading to iliopsoas tendon friction, partial tear, inflammation, and muscle atrophy. Always scrutinize the cup edge and overlying tendon.

• The finding is most relevant in anterolateral surgical approaches where cup anteversion may be reduced.
• The exposed metal edge directly abrades the iliopsoas tendon, causing chronic friction injury.
• Consequences include partial tendon tear, secondary inflammation, and eventual iliopsoas muscle atrophy.
