Radiological Assessment

• The "ball" sits well into the "socket".
• The femoral heads are evenly rounded and a narrow, even and parallel joint "space" (in fact the articular cartilage) can be identified.
• The skyline of the femoral neck is free from irregularity - there is no sign of osteophyte formation.
• The medial flattening of the femoral head is normal - the attachment of the Teres ligament.
