Freeman-Sheldon syndrome with unusual hand and foot anomalies.

ABSTRACT

A newborn with the characteristic facies of Freeman-Sheldon syndrome (whistling face syndrome) and unusual hand and foot anomalies is reported. Flexion contractures of fingers were so severe as to prevent their extension. Previously reported patients with similar hand anomalies had only mild to moderate limitation of extension. Over 75 percent of the 29 previous cases of this syndrome had equinovarus deformity. Not only was this deformity absent but the patient had polysyndactyly of the big toe, an anomaly not previously associated with this syndrome.
