All patients had open physes and underwent MRI after a sports injury. Notch volume was calculated through manual segmentation of notch boundaries seen on axial 1.5\u2010T proton density\u2013weighted images. Two\u2010dimensional (2D) measurements (notch width and notch width index) were made on coronal proton density\u2013weighted MRI studies.
