Abstract

To clarify the diversity of TW2 skeletal maturity, spline-smoothed individual velocity curves of the RUS, Carpal and 20-Bone scores of 44 Tokyo girls of which menarche was recorded correctly, were obtained. On these curves 21 variables of age, intensity, and scores at take-off and at peak velocity, and scores at menarche were obtained. Three subject girls lacked the RUS maturity peak, 10 girls lacked the Carpal maturity peak, and 7 lacked the 20-Bone maturity peak. On an average, the Carpal and 20-Bone score take-offs occur at age 7.8, followed by the RUS score take-off at age 9.5; thereafter the Carpal score peak occurs at age 9.1, the 20-Bone score peak at age 9.6, and the RUS score peak at age 11.8; finally, a half year later, at age 12.3, the menarche occurs.
