What is the primary purpose of bone age assessment in pediatric endocrinology?

• A. To assess skeletal maturation and pubertal timing
• B. To measure bone mineral density
• C. To diagnose scoliosis
• D. To assess liver size

Answer: (A)

Bone age assessment is used to gauge how far a child’s bones have matured compared with their chronological age, which helps determine skeletal maturation and the timing of puberty. By comparing a hand and wrist radiograph to standard reference standards (such as the Greulich and Pyle atlas or Tanner-Whitehouse scoring), clinicians can estimate whether maturation is delayed, normal, or advanced. This information is crucial for evaluating growth disorders, planning or adjusting growth-promoting therapies, and predicting adult height, as well as identifying conditions like precocious or delayed puberty. Bone mineral density, scoliosis, and liver size are assessed with different tools and purposes—DEXA or other imaging for bone density, spine radiographs for curvature, and abdominal imaging or exams for liver size—so they do not reflect skeletal maturation or pubertal timing in the way bone age does.
