This patient is a female infant who was referred to radiology by pediatrics for ultrasound evaluation of subluxable hips.
Pt's medical history was significant for in-utero breech position, delivered via C-section and noted to have a left hip click. Pt was initially referred for a left hip ultrasound to rule out ddh. This US was followed-up approximately one month later with another bilateral hip US.
27June: Bilateral abnormalities of hips by sonographic imaging. Right hip is 40% seated in the acetabulum. Alpha angle of 53-55 degrees on right hip. Left hip is 30-40% covered by acetabulum. Alpha angle of 52-55 degrees on left hip. The impression was bilateral ddh.
26July: Bilateral hip US done at follow-up in the standard coronal and axial planes. The right hip is normal, (improved compared to previous). Femoral head 50% covered by acetabulum (alpha angle 59 degrees). Dynamic imaging of right hip shows no evidence of ligamentous laxity. Left hip is approx 40% covered by acetabulum (alpha angle 51 degrees). Left hip does show ligamentous laxity on stress imaging. The impression was persistent ddh of left hip with 40% coverage and a 51 degree alpha angle.
