Abstract
The aim of this study was to compare three methods that evaluate skeletal maturity: the method of Greulich and Pyle (1959) based on hand-wrist radiographs, the method of Lamparski (1972) (cervical vertebrae method: CVM1) and the method of San Roman et al. (2002) (cervical vertebrae method: CVM2) based on cervical vertebrae radiographs. In addition, the reliability, the validity and reproducibility of these three methods were determined. The hand-wrist radiographs and the lateral cephalometric radiographs of 392 children (195 girls and 197 boys; aged 7-18 years) were used for statistical analysis. One week later, the intraexaminer reliability and reproducibility of the three methods was reviewed by 30 randomly chosen hand-wrist radiographs with their corresponding cervical vertebrae radiographs. Agreements from 60-87% were established by the cervical vertebrae method and 43% (40% deviation only 6 months) by the hand-wrist method.
The morphology of the second (C2), third (C3) and fourth (C4) cervical vertebra body was investigated and the stage of skeletal maturation was determined. To compare the skeletal maturation from CVM 1 and 2 with the skeletal age from the hand-wrist method we had to convert the stage of CVM 1&2 into a skeletal age. We created a regression equation to obtain the cervical vertebral bone age. A simple regression equation as a function of CVM1 stage (x) and a multiple regression equation as a function of CVM2 concavity (x1), height (x2) and shape (x3) of the cervical vertebrae bodies determined the skeletale age (y). By analyzing the correlation coefficients between the calculated cervical vertebral age of the CVM1 respectively the CVM2 method and the skeletal age of the hand-wrist radiograph the following values were computed: 0,82 and 0,84 for girls and 0,69 and 0,75 for boys. The correlation coefficients between the cervical vertebral age by the CVM1 respectively the CVM2 method and chronological age are considerably lower. By applying the CVM1 method we received the values 0,68 for girls and 0,60 for boys. By applying the CVM2 method we received the values 0,69 for girls and 0,63 for boys. Therefore, the CVM2 method of San Roman et al. (2002) was superior to the Lamparksi method.
The results show that the cervical vertebrae on radiographs can replace the hand-wrist radiograph in the evaluation of the skeletal maturaty and that the additional roentgen exposure can be avoided.
