Dislocation of the hip-dysmorphism syndrome is a rare multiple congenital anomalies syndrome characterized by bilateral congenital dislocation of the hip, characteristic facial features (flat mid-face, hypertelorism, epicanthus, puffiness around the eyes, broad nasal bridge, carp-shaped mouth), and joint hyperextensibility. Congenital heart defects, congenital dislocation of the knee, congenital inguinal hernia, and vesicoureteric reflux have also been reported. There have been no further descriptions in the literature since 1995.
