“…In a recent publication, he reviewed historically the main methods of calculating bone age and predicting adult height in the hand and tarsal regions, including his own studies [10].The methods proposed by Ebrí Torné B to study bone age in the carpus and tarsus were applied in a large cross-sectional study of 5,225 healthy children by the carpal IVO (bone valuation index) method and in 540 normal children and 96 fetuses, cross-sectional study, by the Tarsian IVO method. All these contributions were published for several years [11][12][13][14][15][16][17]. Recently, Ebrí Torné B and Ebrí Verde I, studied a longitudinal series of normal children to calculate the bone age and prediction of adult height, using three ossificative indexes: IC (carpal), IMF (metacarpophalangeal) and ICMF (Carpo-metacarpophalangeal).…”
