Prenatally diagnosed fetal split-hand/foot malformations often accompany a spectrum of anomalies.

The purpose of this series was to identify cases that appeared on sonography to be split-hand/foot malformations (SHFMs) in fetuses and correlate the sonographic findings, including 2-dimensional (2D) and 3-dimensional (3D) sonography, to outcomes. A retrospective review was conducted of sonographic studies from 2002 to 2012 at 2 fetal care centers. Data were collected with respect to the morphologic characteristics of split-hand/foot abnormalities, the utility of 3D sonography, associated anatomic abnormalities, family histories, gestational ages at diagnosis, fetal outcomes, karyotype, and autopsy results.
