Abstract
Previously described radiological signs of Turner's syndrome were evaluated in X‐rays of the left hand from 17 patients with Turner's syndrome (age 10.4–15.3 years) and 17 age‐matched girls with constitutional short stature. While none of the signs clearly distinguished between the two groups, ballooning of the tips of the terminal phalanges with a high ratio between the tip and mid‐shaft diameters seemed to be the most useful sign of Turner's syndrome. Disproportionately long phalanges in the 4th finger and the presence of a coarse reticular pattern in the carpal bones appeared to be the next most useful signs. The presence of a short 4th metacarpal or a narrow carpal angle, and assessment for Madelung's deformity were of little value in distinguishing between the two groups.
