Bone age is the degree of a person's skeletal development. In the United States, the most common technique for estimating a person's bone age is to compare an x-ray of the patient's left hand and wrist to a reference atlas containing x-ray images of the left hands of children considered to be representative of how the skeletal structure of the hand appears for the average person at a given age. doi: 10.1136/adc.2005.090134, 121. Age Determination Procedures for Custody Decisions. Children with short stature and no identified cause and children with certain other identifiable causes of short stature should be referred to a pediatric endocrinologist. The remaining cartilaginous portions of the epiphyses become thinner. 107. (2007) 92:3712. [24] The Sontag method uses x-rays of all the bones and joints of the upper and lower limbs on the left side of the body. In many European countries, the increase in illegal immigration and above all the immigration of children and adolescents unaccompanied by parents and without identity documents posed important doubts and stressed the need for new procedures aimed at ensuring a better assistance and protection for young people. These different methods are characterized by a significant and variable intraindividual variability with values ranging from 0.96 to 0.74 years, which seems to be strongly affected by several factors including ethnicity, gender, and pubertal age (93105). Tanner-Whitehouse method of assessing skeletal maturity: problems and common errors. doi: 10.1210/jc.2006-1645, 13. doi: 10.1210/jc.82.5.1603, 86. Growth and reproductive outcomes in congenital adrenal hyperplasia. doi: 10.1210/jc.2008-2474, 133. During puberty, the contours of the epiphyses begin to overlap, or cap, the metaphyses.

History and physical examination findings should guide further evaluation for pathologic causes of short and tall stature. Clin Pediatr Endocrinol. doi: 10.1159/000329372, 11. Search dates: June and December 2014, and March 2015. 2nd ed. Herman-Giddens ME. In patients with pituitary gigantism, octreotide (Sandostatin) and pegvisomant (Somavert) have been used to suppress the growth hormone.19. Arch Dis Child. High intake of phytoestrogens and precocious thelarche: case report with a possible correlation. [1 2 3]The two major methods of BA assessment used commonly are i . Chronological age and bone age were 8.7 4.0 and 8.8 4.3 years, respectively, for the entire population. Klein KO, Newfield RS, Hassink SG. (2015) 42:3027. Lejarraga H, Guimarey L, Orazi V. Skeletal maturity of the hand and wrist of healthy Argentinian children aged 4-12 years, assessed by the TWII method. Bone age determination in eutrophic, overweight and obese Brazilian children and adolescents: a comparison between computerized BoneXpert and Greulich-Pyle methods. Bone age is the degree of maturation of a child's skeleton ().The assessment of bone age and its comparison with chronological age are particularly useful in pediatric endocrinology for estimations of an individual's final height and to study other growth problems in clinical pediatrics (2,3). For specific medical advice, diagnoses, and treatment, consult your doctor. According to a recent study, the BoneXpert method is affected by obesity to a lesser extent than the GreulichPyle method. Assessment of bone age is often required during international immigration programs (68, 69). Karger editor. X-ray exam: bone age study. Evaluation for pathologic etiologies is guided by history and physical examination findings. Exercise before puberty may confer residual benefits in bone density in adulthood: studies in active prepubertal and retired female gymnasts. 69. Eur J Pediatr. (2009) 58:38290. [5][17] The reason for imaging only the left hand and wrist are that a hand is easily x-rayed with minimal radiation[18] and shows many bones in a single view. The images obtained by hand and wrist X-ray reflect the maturity of different bones. Philadelphia, PA: Mosby (2008). (1998) 49:3740. 112. (2018). Pathologic causes of short stature include chronic diseases; growth hormone deficiency; and genetic disorders, such as Turner syndrome. Figure 1. Relationship between height age, bone age and chronological age in (2013) 106:3415. In fact, bone age can provide important information for athletes in order to distribute physical, human, and monetary resources properly (6567). Das S, Ghosh R, Chowdhuri S. A novel approach to estimate age and sex from mri measurement of liver dimensions in an Indian (Bengali) Population A pilot study. In order to achieve a greater accuracy and diagnostic reproducibility, it is important that bone age determination has the lowest intra- and interoperator variability. Since then, more than 15 new computerized automatic systems have been developed (128, 129). It is also common in chronic inflammatory states or infectious diseases, such as juvenile idiopathic arthritis and states of immunodeficiency (3037). 114. Girls: 8 to 12 cm (3 to 5 in) Boys: 10 to 14 cm (4 to 6 in) However, in children with certain conditions (e.g., growth hormone deficiency), normal . N Engl J Med.

These are based on longitudinal data from 116 boys and 95 girls of the Harpenden Growth Study and the London group of the . Arntzenius A, van Galen L. Budesonide-related adrenal insufficiency. In particular, subjects with severe hypothyroidism may have a delayed bone age. Length should be measured using a horizontal rule in children younger than two years, and height should be measured using a wall-mounted stadiometer in children older than two years. Br Med Bull. Assessing the skeletal maturity of the hand-wrist: FELS method. Rofo. J Forensic Sci. Am J Clin Nutr. doi: 10.1055/s-2000-3766, 89. Peak height velocity (PHV) occurs at the average age of 11 years for girls and at the average age of 13 years for boys. [2][5] Studies of bone age in children allow physicians to correlate a child's current height and bone age to their predicted future maximum height in adulthood.[3][5]. The best time to start and stop such therapies can be determined based on a patient's bone age. (2009) 154:2437. A total 156 samples were selected convenient sampling to make comparison of bone age and chronological age between thalassaemic children (age 9-15years) and age sex matched normal control. http://www.who.int/childgrowth/standards/en/. By contrast, subjects with hyperthyroidism may present precocious puberty associated with advanced bone age (18, 19). Kim JR, Lee YS, Yu J. The Centers for Disease Control and Prevention (CDC) and the American Academy of Pediatrics recommend using the World Health Organization (WHO) growth charts for children younger than two years and the CDC growth charts for children older than two years.5 The CDC growth charts are a population-based reference that include data from bottle-fed and breastfed infants. Standard deviation score charts of skeletal maturity and its velocity in Swedish children assessed by the Tanner-Whitehouse method (TW2-20). The Nemours Foundation. In several conditions involving atypical growth, bone age height predictions are less accurate. doi: 10.1093/med/9780199782055.001.0001, 10. In these normal boys, the chronological age at onset of puberty was 11.4 0.8 years (mean S.D.). These systems use different algorithms; thus, no standardized and universally accepted indexes have been proposed so far (130, 131). Acta Paediatr Scand. Forensic Sci Int. Clin Endocrinol. Schlesinger S, MacGillivray MH, Munschauer RW. Tanner JM WR, Cameron N, Marshall WA, Healy MJR, Goldstein H. Assessment of Skeletal Maturity and Prediction of Adult Height (TW2 Method). Tanner JM, Gibbons RD. Available online at: www.thelocal.se/20170307/sweden-begins-newasylum-seeker-age-assessment-tests. Although most children with short or tall stature have variants of normal growth, children who are more than three standard deviations from the mean for age are more likely to have underlying pathology. Thereafter, the pisiform and the sesamoid become recognizable. The two diseases that were most often identified in the studied cohort were celiac disease and an abnormality of the growth hormone axis.3 If history and physical examination findings do not suggest a cause, a complete blood count, comprehensive metabolic panel, and measurement of bone age, insulinlike growth factor 1, and insulinlike growth factor binding protein 3 might be useful to screen for chronic disease and growth hormone deficiency. For this reason, pediatricians should evaluate patients on the bases of all the available knowledge about the child, particularly their personal growth history. In addition, children with PA appeared to be affected by a BA . Nowadays, many methods are available to evaluate bone age. Just as there is wide variation among the normal population in age of losing teeth or experiencing the first menstrual period, the bone age of a healthy child may be a year or two advanced or delayed. Am J Roentgenol Radium Ther Nucl Med. a systematic review and meta-analysis. Springfield, IL: Charles C. Thomas. Not only hormones but also gender might affect this process. At this stage, children should track along a percentile, and variation should stay within two large bands on the growth chart. Table 5 lists the indications for referral.2,6,22. Bone age - Wikipedia Heyman R, Guggenbuhl P, Corbel A, Bridoux-Henno L, Tourtelier Y, Balencon-Morival M, et al. (2000) 172:5536. Awais M, Nadeem N, Husen Y, Rehman A, Beg M, Khattak YJ. There is a separate equation for each half year of chronological age; and for pre- and postmenarcheal girls at ages 11 to 14. Usually, the first ossification center to appear is in the context of capitate and hamate at the second month in female individuals and around the fourth month in male individuals and remain the only useful observable features for the next 6 months. A score is assigned to each bone based on maturation and sex of the patient. Common causes of tall stature include familial tall stature, obesity, Klinefelter syndrome, Marfan syndrome, and precocious puberty. This process is characterized by a predictable sequence of development and progression of ossification centers. Salsberry PJ, Reagan PB, Pajer K. Growth differences by age of menarche in African American and White girls. IEEE Trans Med Imaging. X-rays are commonly done in doctors offices, radiology departments, imaging centers, and dentists offices. The choice of the left hand depends on the fact that, at the time of sampling, the left hand was the less frequently impaired (at that time, many boys used to work in factories, and they could have suffered accidents at work). Age, height, weight, BMI z-score, and BA/CA were similar in the PA and control groups . Table 3. . Gilsanz V, Kovanlikaya A, Costin G, Roe TF, Sayre J, Kaufman F. Differential effect of gender on the sizes of the bones in the axial and appendicular skeletons. The TannerWhitehouse method was developed in 1,930 using data obtained in European children (3, 113). 29. doi: 10.1259/0007-1285-67-801-848, 95. The issue here is the size of the standard deviation (SD) of the difference between bone age and chronological age, which is 15 months or more. [5] For example, a patient's bone age may be less than their chronological age suggesting a delay in growth as may be caused by a growth hormone deficiency. (1995) 126:54550. Therefore, carpal bones are not ossified at birth, and this process typically advances from the center of ossification (80). An individual weighing 18.5 kg/height/height is considered to be underweight and thus below the 5 th percentile. Calculating the midparental height (Table 1) is an important part of the evaluation because most short or tall children have short or tall parents. Among them, the most used is based on the tables developed by Bayley and Pinneau in 1946 and revised in 1959. (2007) 356:47985. Moreover, even when there is a good correlation between predicted and actual adult height, there is a wide individual variation, with almost 30% of adults differing by more than 5.0 cm from the BP predicted height (141). Acta Paediatr Scand. CG has organized the material. doi: 10.1080/03014469700004982, 120. During a hand and wrist X-ray procedure, the child is exposed to <0.00012 mSv of radiation, thus lower than other daily physiological risk (86), however resulting in irrelevant relative risk of 40-year mortality equal to 5.1 108 (calculated for an exposure dose of 0.00015 mSv) (8789). doi: 10.1515/JPEM.1994.7.2.141, 129. Few pediatric devices were approved after a clinical trial involving children. Tall stature has the same prevalence as short stature, but it is a much less common reason for referral to subspecialty care. (2015) 51:235. doi: 10.1111/jpc.12837, 61. Henley DV, Lipson N, Korach KS, Bloch CA. Following the growth charts from the CDC, the average height of adult woman at age 20 is 64-65 in (163 cm). A child whose growth is initially normal but then falls progressively further off the growth curve may have growth hormone deficiency. Common normal variants of short stature are familial short stature, constitutional delay of growth and puberty, and idiopathic short stature. Doctors assign a childs bone age based on which standard X-ray images in the atlas most closely match how the child's bones look on the X-ray. Is the Greulich and Pyle atlas applicable to all ethnicities? As sex steroid levels rise during puberty, bone maturation accelerates. medicolegal cases). (1995) 154:627. doi: 10.1007/BF02079065, 142. Congenital hypothyroidism leads to growth arrest, delayed bone age, and short stature at birth. The long bones are those that grow primarily by elongation at an epiphysis at one end of the growing bone. J Pediatr Gastroenterol Nutr. Multiple regression equations for predicting the adult height of boys and girls from height and bone age at ages 4 and upwards are presented. Furthermore, the image was digitized and transformed into a series of mathematical coefficients produced mostly from standard image of the left hand and wrist X-rays. Among these, three methods were the most representative and used worldwide: The GreulichPyle method, the TannerWhitehouse, and the Fels method.

Assessment of skeletal maturity of the hand-wrist and knee: a comparison among methods. Horm Res. Bone age may be significantly advanced in genetic overgrowth syndromes, such as Sotos syndrome, Beckwith-Wiedemann syndrome and Marshall-Smith syndrome. 47. For this reason, in the TW3 method, skeletal age evaluation ends at 15 years in women and 16.5 years in men (while in the TW2 set, 18 and 19 years, respectively, with a bone maturity anticipation of 2.53 years) (120). doi: 10.1056/NEJMoa064725, 62.

[10][11] Since then, updated atlases of the left hand and wrist have appeared,[12][5] along with atlases of the foot and ankle,[13] knee,[14] and elbow. (1987) 14:35765. Bone Age | SpringerLink doi: 10.1159/000023352, 115. The bone mineral density (BMD) of the lumbar spine (L1-L4) was measured by dual energy x-ray absorptiometry (Hologic QDR 1000) in 135 healthy caucasian children, aged 1-15 yr, and values were correlated with age, height, weight, body surface, bone age, pubertal status, calcium intake, vitamin D supplementation, and serum bone gla protein.
