Skeletal Age Assessment of SMI and MP3 Stages to Predict the Pubertal Growth Spurt / 대한소아치과학회지

This study aimed to assess the skeletal age of skeletal maturational indicator (SMI) and middle phalanx of the middle finger (MP3) stages and to predict the SMI and MP3 stages corresponding to pubertal growth spurt in boys and girls respectively.The skeletal age was assessed from hand-wrist radiographs of 363 children (182 boys, 181 girls) aged 7 to 16 years by radiologists using the Korean standard bone age chart. Also, SMI and MP3 stages were evaluated from the radiographs. From these records, the mean skeletal age of SMI and MP3 stages was calculated.The stages including pubertal growth spurt were SMI 4 – 5, MP3 FG – G stages in boys and SMI 3 – 4, MP3 F – FG stages in girls.
