한국아동골격성숙상에 關한 硏究 = A Study on the Skeletal Maturation of Korean Children

다국어 초록 (Multilingual Abstract)

The assessment of skeletal maturation by means of the Todd, Greulich & Pyles inspectional method, among others, has established its place in the evaluation of the growth and development of children in health and disease. Furthermore, this method has found its practical application in predicting adult heights and leg lengths which has proved to be a valuable aid in the field of orthopedic surgery.
Few reports are available so far in this country on the skeletal maturation of Korean children except that of Han(1962) which is mainly concerned with the time of appearance of the ossification centers in the hands and feet, and that of Park (1962) which dealt with the subject of skeletal maturation and development of Korean children in a rather extensive but somewhat obscure way.
The present study investigates skeletal maturation of Korean children through roentgenograms from age 7 to full maturity in the hands, and from age 13 to maturity in the knees.
The assessment of bone and skeletal age was made by employing Greulich & Pyles Hand Atlas and Pyle & Hoerrs Knee Atlas, respectively, as standards of reference.
The briefly summarized findings are as follows:
1. The ages of onset aEd order of the ossification in the hands showed a wide range of variation. The order of appearance of ossification centers in the carpal bcne of the male children was not necessarily the same as that of Standard Children.
2. Completion of ossification in the hands commenced from the carpal bones and ended with the closure of the distal radial epiphysis at the age of 18 years 5 months in the male and 17 years 3 months in the female. Using the Harvard Matnrity Series for comparison, the time of completion of ossification was delayed on the average by 4 months in the male, and 14 months in the female.
3. The fusion time of the distal femoral and the proximal tibia1 epiphysis was 17.5 years in the male and 16 years in the female, while fibula closed after 17 years 11 months in the male and 16.5 years in the femal.
4. Bone ages of 30 ossification centers in the hands showed a wide range of variations at each age level in both sexes. The average bone age of each ossification center showed a variable amount of retardation compared to Standard Children. The average of the difference in the bone ages through whole age levels showed maximum value in the lunate of the male, and the distal ulnar epiphysis, lunate and scaphoid of the female.
5. Skeletal ages of the hand showed a variable amount of retardation compared to Standard Children at each age level in both sexes. The average of the difference through all age levels was 11 months in the male and 13 months in the female, reaching its peak of difference at age 11 in both sexes. The period of maximum difference was inferred as due to the different timing of the maturation spurt, comparable to the prepubertal growth spurt, as its principal cause. Menarcheal age in this female group was 14 years 8 months. It was postulated that the mechanism, which causes retardation in the menarcheal age of Korean girls, was also responsible for the difference in maturation rate and pattern at least, in the prepubertal period in femaie groups.
6. It was realized that a different skeletal age norm is needed among different races, which show a The standard of the skeletal maturation of Korean children from age 7 to maturity was presented, and
7. Ccmparison with Chinese and Japanese children showed less dissimilarities in the rate and pattern of maturation than in comparison with Standard Children.
8. Bone and skeletal age of knees showed less retardation in the male groups, and comparable delay with hands in the female groups. Skeletal age of hands and knees did not necessarily correspond and this feature was more conspicuous in the male groups. quite different rate and pattern of skeletal maturation. its course of selection was described.
9. Hands were considered as more reliable and convenient in assessing skeletal maturity.
10. Korean girls are generally less precocious than boys in their respective skeletal maturation rates when compared with American children.
11. Skeletal maturation has a close relationship with body maturation and growth.
12. Bayleys Prediction Table for Adult Heights and Anderson & Greens Prediction Chart for Leg Lengths may be applied to Korean children with some qualification.
