16. EXAMINATION OF: Right hip. DIAGNOSIS: Primary unilateral osteoarthritis right hip. ONE-VIEW RIGHT HIP: A single frontal view is obtained of the right hip. No previous studies are available for comparison. Right hip arthroplasty is seen. Alignment appears grossly unremarkable on this single view. There are skin staples present. Air is seen in the soft tissues, likely due to recent surgery. There appear to be two drains present. The tip of one overlies the soft tissues superolateral to the greater trochanter. The second one is more inferior. The tip overlies the right proximal femoral prosthesis. IMPRESSION: Single view of the right hip with findings consistent with recent right total hip arthroplasty.
