Slipped capital femoral epiphysis: ultrasonographic findings.
Slipped capital femoral epiphysis (SCFE) is an uncommon skeletal disorder of adolescence often overlooked because of its nonspecific clinical presentation. Anteroposterior radiography may fail to demonstrate a minimal slip even when clinical examination raises suspicion of the disease. On the other hand, prompt diagnosis is essential to obtain better therapeutic results. In our patient population joint effusion, which often accompanies SCFE, was readily recognized and quantified by ultrasonography (US). US also permitted recognition of the initial SCFE and assessment of the degree of slip by measuring the height of the physeal step. As to metaphyseal remodeling, plain radiography seems to be more informative than US; however, US has a role in the follow-up of SCFE because of the risk of slippage in the contralateral hip. This work suggests that US is useful as a primary imaging tool in the evaluation of subjects with limp or hip or knee pain to rule out SCFE.
