Abstract Purpose This study describes spinal growth and predicts future growth by standardizing timing relative to the growth spurt. Methods From a longitudinal cohort of normal, healthy children followed through their growth, we identified those who completed their growth and compared spinal heights to chronological age and timing relative to the growth spurt. Anthropometrics and radiographs were correlated to identify heights to C1, T1, and S1 using three separate methods with validation performed by comparing to heights predicted by pelvic width. Heights and spinal lengths were normalized to percentages of adult lengths, and multipliers of growth remaining determined for both age and timing relative to PHV 90% (peak height velocity defined by achieving 90% of final height) as adult length divided by current spine length. The age at PHV 90% is termed Peak Growth Age (PGA) 90% . Results Fifty-four subjects completed their growth at the study terminus (35f, 19 m). We identified multipliers allowing calculations of adult spine length based on the child’s current timing relative to peak growth. At PHV 90% , children were 90% adult total height and 87% adult spine height. During childhood, spinal growth is 1.55 ± 0.21 cm/yr in girls, 1.14 ± 0.23 cm/yr in boys increasing to 1.75 ± 0.11 cm/yr in girls and 2 ± 0.11 cm/yr in boys during the growth spurt. Conclusion This study identifies multipliers of spinal growth determination and identifies their values relative to the adolescent...
