Modified Greulich-Pyle, Tanner-Whitehouse, and Roche-Wainer-Thissen (knee) methods for skeletal age assessment in a group of Italian children and adolescents

Abstract: Modified Greulich-Pyle (GP), Tanner et al. 2, radius, ulna and short bones (TW2-RUS), TW2-20-bone and Roche-Wainer-Thissen RWT (knee) skeletal age assessments were made in an Italian population sample of 128 males and 93 females aged 4.1-16.9 years. All the scales appear to be well-suited to the Italian population despite minor differences. A very high correlation was found between the assessment of knee skeletal ages by the RWT method and that of the hand-wrist by the GP and TW2 systems in the same subject wi… Show more

“…Maresh (12) findings imply that a standard growth curve should be prepared by each country in order to assess any existent growth abnormality and to predict future growth at skeletal maturity, and that these be revised on a regular basis. Assessment of bone age also depends upon the standards used, e.g., the TW-2 method, the TW-1 method, the Greulich and Pyle atlas, and the Roche-Wainer-Thissen (knee) method (15)(16)(17)(18). In the present study, bone age was assessed by the modified TW-2 method (4).…”

“…However, its accuracy is impaired by the trend towards earlier maturation reported in most European populations over the last 30 years with respect to the original scale of the method [2, 3, 4]. As regards the Italian population, the TW method presents a slight lag in maturation with respect to the British standardising group at young ages and a 7- to 9-month advancement at pubertal ages in both sexes [5, 6, 7, 8]. …”

“…Em contraste, outros autores têm encontrado uma subestimativa da idade para ambos os sexos. 12,13,15,16,27 O AV superestimou as idades para meninas e meninos, sendo esta superestimativa maior para o sexo feminino. Para o TW3-RUS se constatou uma superestimação nas meninas e uma subestimativa para o masculino, porém é importante salientar que as idades ósseas foram próximas a IC, como foi encontrado Vignolo et al 18 (1990), HaiterNeto et al 28 Em relação às diferenças (totais) entre a IC e as idades ósseas estimadas, estas foram estatisticamente significativas para os métodos baseados em atlas.…”

“…1 Alguns autores têm investigado a aplicabilidade dos métodos de GP e TW em indivíduos com características genéticas, étnicas, socioeconômicas e ambientais diferentes da amostra empregada para padronizá-los. [7][8][9][10][11][12][13][14][15][16] Vários trabalhos tem demonstrado uma subestimativa da IO em relação à idade cronoló-gica quando se utiliza o método de GP, tal como foi constatado em australianos 7 , brasileiros [8][9][10] , finlandeses 11 , indianos 12 , italianos 13 , em indivíduos de Europa central 14 , malawenses 15 e turcos. 16 Quando se emprega o método TW, as idades ósseas estimadas são muitas vezes maiores que a IC, o que tem sido observado em argentinos 17 , italianos 18 e japoneses.…”
