The alpha angle as a predictor of contralateral slipped capital femoral epiphysis

Journal of Children's Orthopaedics, 2016
Purpose Contralateral hip involvement in slipped capital femoral epiphysis (SCFE) is common. Femoral head−neck asphericity, as measured by an elevated alpha angle, has not previously been assessed with respect to SCFE risk.
