Growth plates are located at the end of
long bones and are responsible for
lengthening of the bones. The open
growth plates look like black lines on x-
ray growth plate exam.
WHEN DO GROWTH PLATES CLOSE?
The closure of growth plates starts during
the peripubertal age which is 12-14 years
old in girls and 14-16 in boys. Precocious
puberty (Developing puberty signs early)
can arrest height prematurely by closing
growth plates too soon.
GROWTH PLATE EXAM
Growth plate examination is
performed by analyzing growth
plates and bones with hand x-rays.
After the x-ray exam, kids’ bone
age and their final adult height is
calculated by AI software
technology.
WHEN IS GROWTH PLATE EXAM NEEDED?
When a child is growing less than 2 inches a year
When a child has significantly short stature compared to their peers
When you want to check if a child can benefit from growth hormone treatment
PRECOCIOUS PUBERTY
Precocious puberty is the onset of puberty in a child at an age that is significantly earlier than their peers. Children with precocious puberty have much advanced bone age on growth plate exam.
EFFECT ON ADULT HEIGHT
Children with precocious puberty are initially taller than their classmates. However, precocious puberty leads to a premature closure of growth plates resulting in shortened adult height.

I Grow clinic offers medical treatments for children who started puberty earlier than their peers. The treatment is to allow enough time for kids to grow. Preventing early closure of growth plates can improve final height in children.
