A one-month-old male infant with hydrocephalus, aqueductal stenosis and congenital clasped thumbs is reported. Electromyographic evaluation supported the hypothesis that the clasped thumbs were a consequence of flexion-extension imbalance, with subsequent muscle contracture secondary to hypoplasia or aplasia of the thumb extensors.
