Precocious puberty is usually associated with which bone age finding?

• A. Advanced Bone Age
• B. Delayed Bone Age
• C. Normal Bone Age
• D. Variable Bone Age

Answer: (A)

Precocious puberty speeds up skeletal maturation, so the bone age tends to be ahead of the child’s chronological age. Bone age is assessed from a hand and wrist X-ray and reflects how far the bones have matured compared with what's typical for the child’s actual age. When puberty begins early, estrogen (in girls) or testosterone (in boys) accelerates bone development, leading to an advanced bone age. That is why an advanced bone age is the usual finding in precocious puberty. Delays in bone age occur with malnutrition or endocrine issues like hypothyroidism and are not characteristic of early puberty. A normal bone age means the bones are maturing in step with chronological age, which doesn’t align with precocious puberty. Variable bone age isn’t a typical pattern for this condition and would not reliably indicate early pubertal timing.
