Remodeling in slipped capital femoral epiphysis: sonographic assessment after pinning.
Twenty-one children and 26 hips with recent slipped capital femoral epiphysis (SCFE) underwent serial sonographic examination after operative fixation. The initial sonographic step at the anterior outline of physis decreased as a result of metaphyseal resorption. The first signs of resorption were evident 3 weeks after onset of symptoms; thereafter, the rate of resorption was 2 mm for each 3 weeks of follow-up. Finally, the physeal step was smooth and the anterior aspect of the femoral neck was straight. Sonography is accurate and free of projectional errors in assessment and classification of remodeling in SCFE.
