Abstract

Hypoplasia of the ischiopubic region is described in four patients. An adolescent was referred for spinal dysraphism and scoliosis, another one for bilateral aplasia of the patella and scoliosis, and finally two children were treated for congenital dislocation of the hip. The osseous malformation of the ischiopubic bones was not associated with any other intrapelvic disorders, and remained unchanged until skeletal maturity. The appearance of this extremely rare anomaly is usually reported as a syndromic constituent of a limited number of congenital malformation syndromes that can be widened to include congenital dislocation of the hip.
