Fig. 3.
(Left) Shows a girl of 16 with an untreated curve of 30°. Her apophysis has attached with a slight interruption of the excursion across the left pelvis. (See arrow.) (Right) Shows the girl over 15 years later. She is now a young adult. Although it has been 15 years since her last roentgenogram was taken, showing a curve of 30° and an attached iliac apophysis, her curve remained unchanged at 30°. The iliac apophysis has solidified and is now a part of the ilium. (See arrows.)
