Fig. 2From: Spinal growth velocity versus height velocity in predicting curve progression in peri-pubertal girls with idiopathic scoliosisA demo case illustrating the influence of variations of growth velocity in relation to fluctuation of curve progressive velocity. a: Longitudinal curves of height velocity, spinal growth velocity, angle velocity and Cobb angle were constructed respectively. a & b: peak angle velocity occurred simultaneously with PSGV but not PHVBack to article page
