What is a Digital X-Ray of Bone Age?
A bone age X-ray is a simple imaging test that estimates how mature a child's bones are compared to their actual age. It is done by taking a digital X-ray of the left hand and wrist, where the growth plates are clearly visible. Doctors use it to assess whether a child is growing at a normal rate for their age.
Why is a Bone Age X-Ray Done?
- To evaluate children who appear shorter or taller than expected for their age
- To investigate early or delayed puberty
- To monitor children on growth hormone treatment
- To estimate how much more growth a child has remaining
- To investigate hormonal disorders such as hypothyroidism or growth hormone deficiency
Normal Bone Age Ranges
Bone age is considered normal when it matches the child's actual (chronological) age within about 2 years:
| Bone Age vs. Actual Age | Interpretation |
|---|---|
| Within 2 years of actual age | Normal |
| More than 2 years behind actual age | Delayed bone age — may suggest growth disorder |
| More than 2 years ahead of actual age | Advanced bone age — may suggest early puberty or excess growth hormone |
A radiologist compares the child's X-ray with standard reference charts (such as the Greulich and Pyle atlas) to determine bone age. The result is always interpreted alongside height, weight, and hormone tests.
How to Prepare for the Bone Age X-Ray
- No fasting or special preparation is required
- The child should remove any jewellery or metal objects from the hand and wrist before the scan
- The test is painless and takes only a few minutes — the hand is briefly placed on the X-ray plate
- Radiation exposure is very low, as only one small image is taken
- Bring previous growth records or prior X-ray reports if available
