•Confirm reduction
•Baseline of alpha and beta angle
•Perform within 2 weeks of Pavlik harness
•Assess capsular laxity in hip clicks
•Interpretation of USG
•Identify landmark
•Ilium
•Bony acetabulum
•Labrum / abductor muscle
•Femoral head
•Confirm concentric reduction

Assess coverage:

•>50% in
•Labrum pointing upwards
•Labrum pointing inwards
•Measure alpha and beta angle
•Alpha angle: between ilium and bony acetabulum (Normal >60)
•Beta angle: between ilium and labrum (normal <55)
•Graf hip angle measurement
