Figure 1 The growth indicators used in the hand-wrist radiograph [41,42]: 1. PP2=(Having the same width of in the second proximal phalanx epiphysis and diaphysis), 2. MP3=(Having the same width of in the third proximal phalanx epiphysis and diaphysis), 3. Pisi, H1, R=(Ossification of the pisiform, ossification of the hamular process of the hamatum, having the same width of in the radius epiphysis and diaphysis) 4. Sesamoid, H2 (Ossification of adductor sesamoid, progressive ossification of the hamular process of the hamatum), 5. MP3cap, PP1cap, Rcap (Capping of the diaphysis in the middle phalanx of the third finger by the epiphysis, capping of the diaphysis in the proximal phalanx of the first finger by the epiphysis, capping of the diaphysis in the radius by the epiphysis), 6. DP3u (Union of the third distal phalanx epiphysis and diaphysis), 7. MP3u (Union of the third medial phalanx epiphysis and diaphysis), 8. PP3u (Union of the third proximal phalanx epiphysis and diaphysis), 9. Ru (Union of the radius epiphysis and diaphysis).
