Description

Zorab et al reported equations for estimating the height of an adolescent based on tibial length. This is useful for estimating what the normal height would be for a patient with scoliosis or other spinal deformity. The authors are from the Institute of Diseases of the Chest in London.

Parameter:

(1) age group
