[Transverse fetal position syndrome--a combination of congenital skeletal deformities in the newborn infant].

We describe a pattern of connatal postural deformities observed in approximately 0.6% of otherwise healthy, mature newborn infants. It comprises unilateral flattening of the skull (dolichocephalus), ipsalateral mandibular hypoplasia and torticollis, deviation of the septum nasi, pes calcaneovalgus on one and pes adductus supinatus on the other side. The deformities occur in four distinct combinations attributable to the prenatal lie of the fetus: dorsoanterior or dorsoposterior, left or right oblique lie. The deformities respond well to manipulative therapy.
