Only one AP image was provided. There is bilateral slippage of the upper femoral epiphyses. The line of Klein fails to intersect the femoral epiphysis on either side.
Case Discussion
If the line of Klein fails to intersect the epiphysis during the acute phase, it is called Trethowan's sign. Urgent orthopedic referral is advised in these types of cases.
