Disproportionate growth of the lower extremities. A major determinant of short stature in Turner's syndrome
N. D. Neufeld, B. M. Lippe and S. A. Kaplan
The relationships between the height (H), sitting height (SH), and the
lower segment (H-SH) were studied in a group of 21 patients with Turner's
syndrome. The SH/H ratio was markedly abnormal (0.55), equivalent to that
of 6-year-old normal girls. The abnormality in ratio was a result of
markedly shortened lower extremities. Further, there was a significant
inverse correlation between SH/H-SH ratio and height such that patients
with the most shortening of their legs were the shortest. The degree of
abnormality in lower segment, therefore, is a major determinant of stature
in Turner's syndrome.
