Calcaneal and iliac ossification in children likely linked to PHV

Recently published data indicate calcaneal and iliac ossification in children is linked to the peak height velocity of their growth.
Researchers analyzed annual serial radiographs and physical examinations for 94 healthy children between the ages of 3 and 18 years to determine peak height velocity (PHV) of growth via the child’s height. The PHV was then correlated with the degree of calcaneal and iliac ossification by studying the child’s foot and pelvic radiographs.
There were six consistent stages of calcaneal ossification seen in this study, according to the researchers. The first stage occurred at a mean of 4.7 years prior to PHV and progressed in regular intervals until completing a mean 2.1 years following PHV. Each calcaneal stage occurred 2 years later in boys than in girls.
The researchers found fusion tended to begin in the middle of the apophysis and proceed outward. Additionally, iliac ossification was consistently found to occur after PHV. – by Christian Ingram
