Hand anomalies in Crouzon syndrome

Objective. To review the hand radiographs of patients with Crouzon syndrome, to look for extracranial manifestations of the condition at this site. Design. The hand radiographs of those with Crouzon syndrome at tending the Craniofacial Service at Great Ormond Street between 1985 and 1996 were reviewed. Results. Thirty-three patients underwent a total of 34 radiographs, one patient having had a serial study. This revealed a range of minor anomalies. Most striking was the presence of carpal fusions in four cases, a feature which has not previously been reported. Conclusion. The hands of Crouzon syndrome may have anomalies including cat-pal fusions, and these results are evidence that the condition may produce subtle effects on the hands.
