The hands in Saethre-Chotzen syndrome

The hand radiographs of fifteen patients with a diagnosis of Saethre-Chotzen syndrome were reviewed by a radiologist with an interest in skeletal dysplasia along with the craniofacial team. Eleven patients exhibited a range of bone abnormalities of the following sites: thumbs, fingers, metacarpals, and the radius. The epiphysis of the distal phalanx of the thumb was most commonly involved site with 7 of the 15 patients affected. In addition to the structural abnormalities all cases before puberty (14 out of 15 patients in this series) showed variable delay of the bone age.
