Fig. 2From: Differences in vertebral morphology around the apical vertebrae between neuromuscular scoliosis and idiopathic scoliosis in skeletally immature patients: a three-dimensional morphometric analysisThe vertical axis (arrow) was defined as the line passing through the center of gravity (G) parallel to the line connecting the anterior edges of the vertebral foramen on the upper and lower vertebral end plates (a, b). The sagittal plane (S) contained the center of gravity (G) and the anterior edges of the vertebral foramen on the upper and lower end plates (a, b)Back to article page
