Anatomy and management of the leg and foot in Apert syndrome

The involvement of the lower extremity in acrocephalosyndactyly has received less attention than the craniofacial and upper extremity anomalies. The lower extremity deformities are progressive and require greater attention as the patient grows older. The stiffness of the hips and mild to moderate genu valgum rarely, if ever, require intervention. Foot and toe deformities lead to difficulty with malalignment, painful stresses, and shoe wear. Each of these must be dealt with individually, placing emphasis on the underlying bony abnormality.
