Eighteen patients with Crouzon syndrome were evaluated for anomalies o
f the feet. Clinical examination was unremarkable in all cases. Radiog
raphs were evaluated by a radiologist with an interest in skeletal dys
plasia, along with the craniofacial team. A range of radiographic anom
alies was seen, with the phalanges, metacarpals, and tarsals all displ
aying anomalies. Only three cases had radiographically normal feet. Th
ese findings suggest that the effects on the feet, which, although sub
tle and not well described in the literature, are notable. Feet anomal
ies also occur with the other complex craniosynostosis syndromes resul
ting from mutations of fibroblastic growth factor receptor 2 molecule,
such as those of Apert, Pfeiffer, and Jackson-Weiss syndromes.
