Background: Assessments of skeletal age are of great importance for the diagnosis of growth disorders, which are classified into two broad categories of primary and secondary growth defects with different etiologies, prognoses and treatments. Distinction between these categories can be made from clinical findings and skeletal age. "Greulich and Pyle" is the most prevalently employed skeletal age technique, based on the recognition of maturity in hand-wrist radiographs from birth to maturity. On the other hand, sonography is a developing method in examination of soft tissues and has some known advantages such as avoidance of radiation in children. Objectives: The purpose of this study is evaluation of the value of sonographic examination of wrist and hand in estimating bone age in 0-6 years old children. Results: Six children were less than 1 year (4 girls and 2 boys ), 8 children were 1–2 years old (4 girls, 4 boys), 8 children were 2–3 years old (4 girls, 4 boys), 7 children were 3–4 years old (3 girls, 4 boys), 8 children were 4–5 years old (4 girls, 4 boys) and 14 children were 5–6 years old (9 girls, 5 boys). Diagnostic value of sonography for estimation of bone age in comparison with plain radiograph was somehow equivalent, that is statically significant (P = 0.01). Conclusions: Sonographic examination of wrist is a valuable method for estimating bone age in 0–6 years.
