Bone age: PA left hand and wrist

What it is for

A bone age study estimates a child's skeletal maturity by comparing the bones of the hand and wrist with a standard atlas, most often Greulich and Pyle. The radiologist judges which ossification centers have appeared and how much the growth plates have closed. It is ordered for children who are growing too fast or too slowly, for early or late puberty, and for hormone and growth disorders.
