Skeletal maturity in Austrian children assessed by the GP and the TW-2 methods.
Skeletal maturity was assessed in 637 Austrian children from 7 to 16 years of age. The Greulich - Pyle and the Tanner- Whitehouse -2 ( RUS and TW 20-bone) methods were used. The GP ages showed some major deviations at and after puberty, especially in boys. The RUS and 20-bone ages conformed more closely to the standards although a general advancement in RUS ages was seen in girls after the age of 10 1/2. A similar pattern in RUS ages has been reported for other populations and may indicate a secular trend.
