US HIP - INDICATIONS<br />
US is useful for the evaluation of various conditions involving the coxofemoral<br />
joint, surrounding tendons, muscles and bursae. Hip US has proven<br />
to be of great practical benefit when performing aspiration and injection<br />
of the joint<br />
Pathological<br />

Coxo-femoral joint<br />
• Synovitis<br />
• Osteophytes<br />
• Bone erosions<br />
Peri-articular soft tissues<br />
• Tendinitis/Tendinopathy<br />
• Calcifications<br />
• Bursitis
US HIP - JOINT - PATHOLOGICAL CONDITIONS<br />
Synovitis<br />
• Anechoic/hypoanechoic joint cavity wi<strong>de</strong>ning<br />
• Capsular convexity/distension<br />
• Longest bone-capsule distance ≥ 7 mm<br />
• ≥ 2 mm si<strong>de</strong> difference<br />
• Hyperemia (Doppler)<br />
Irregularities of the bony profile<br />
• Osteophytes: irregularities of the bony<br />
profile at the joint margins for new bone<br />
formation<br />
• Erosions: cortical <strong>de</strong>fect with an irregular<br />
floor (both in longitudinal & transverse scans)
