In: Geary DF, Schaefer F, editors. This method is very simple and fast, needing roughly 1.4 min for the evaluation (10, 107), thus explaining why it is preferred by 76% of pediatric endocrinologists and radiologists (10). (2015) 16:2015. doi: 10.1159/000101336, 25. Braz Oral Res. Pediatricians have relied on methods for determining skeletal maturation for >75 years. Ontell FK, Ivanovic M, Ablin DS, Barlow TW. The carpal bones arise from primary ossification centers and continue their calcification in an outward manner. doi: 10.1056/NEJMra021561, 54. However, the GP method requires a continuous and long experience in order to optimize bone age determination. Bone age assessment: a large scale comparison of the Greulich and Pyle, and Tanner and Whitehouse (TW2) methods. (2010) 23:85561. So the confidence interval around the chronological age estimated from bone age is 30 months (i.e. According to a recent study, the BoneXpert method is affected by obesity to a lesser extent than the GreulichPyle method. Ranjitkar S, Lin NH, Macdonald R, Taylor JA, Townsend GC. During growth, biological maturity is defined by several parameters, including the characterization of skeletal maturity, sexual maturity, dental elements eruption, menarche, spermarche, deepening of the voice, growth spurt, and the achievement of 95% of the adult height (13). Among these, three methods were the most representative and used worldwide: The GreulichPyle method, the TannerWhitehouse, and the Fels method. Speiser PW, White PC. [1 2 3]The two major methods of BA assessment used commonly are i . (1990) 17:35576. [3] In certain instances, abnormal growth conditions may be treated with supplemental hormone therapy. Contemporary Pediatrics Resident Writer Program, Food Insecurity and the Dangers of Infant Formula Dilution, Getting into the Roots of Childhood Atopic Dermatitis, Opt-Out Chlamydia Screening in Adolescent Care, The Role of the Healthcare Provider Community in Increasing Public Awareness of RSV in All Infants, | Obstetrics-Gynecology & Women's Health. doi: 10.1016/j.forsciint.2011.09.022, 101. 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. 68. Coefficients used in the RWT method are tabulated to 14 years of age for girls and 16 years of age for boys (138). [5][9] The first atlas published in 1898 by John Poland consisted of x-ray images of the left hand and wrist. doi: 10.1007/s00247-019-04435-z. Malina RM, Rogol AD, Cumming SP, Coelho e Silva MJ, Figueiredo AJ. (2003) 59:77987. Am J Orthod Dentofacial Orthop. (1995) 154:627. doi: 10.1007/BF02079065, 142. J Forensic Sci Med [serial online] 2019 [cited 2020 Jan 31];5:177-80. Constitutional advancement of growth in tall children is the equivalent of constitutional delay of growth and puberty in short children.1,19,20 Children with constitutional advancement of growth have accelerated growth until two to four years of age and then track parallel to the growth curve. J Radiol Prot. 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). doi: 10.1109/TMI.2008.926067, 132.

Am J Clin Nutr. Not only hormones but also gender might affect this process. doi: 10.1159/000184848, Keywords: skeletal development, height, X ray, children, bone age, Citation: Cavallo F, Mohn A, Chiarelli F and Giannini C (2021) Evaluation of Bone Age in Children: A Mini-Review. (2016) 170:16370. History and physical examination findings should guide further evaluation for pathologic causes of short and tall stature. Pak J Biol Sci. Philadelphia, PA: Mosby (2008). This means a child tends to be shorter than average and to enter puberty later than average, while growing at a normal rate. Skeletal age estimation for forensic purposes: a comparison of GP, TW2 and TW3 methods on an Italian sample. The mean bone age is advanced over chronological age by 3 years and results in decreased predicted adult height (-5 to -11 cm compared to target height). It uses feature extraction techniques and calculates bone age by analyzing the left-hand radiograph based on. Horm Res. (1998) 49:3740. (2008) 28:1016. (2009) 94:223944. 4. (2018). doi: 10.1297/cpe.23.27, 55. [24] This technique was created to avoid errors in estimating bone age though to arise from focusing on only one area of the body. (2016) 8:4751. Children with familial short stature or idiopathic short stature have a bone age equivalent to their chronologic age, and children with constitutional delay of growth and puberty or endocrine disorders have a bone age that is less than their chronologic age. Bone age should be compared with chronologic age to narrow the differential diagnosis of short stature.5,10,11 The traditional method compares a plain radiograph of the left wrist and hand to a database of norms, although various methods are now available.1012 Children with normal variations of growth may have advanced or delayed bone age, but a bone age that is more than two standard deviations from the mean for age is likely due to a pathologic condition. For a child's bone age to be considered abnormal, the chronological age must differ from the assigned bone age by more than 2 standard deviations. A healthy body mass index for age (BMI/A) is considered to be between 18.5 to 24.9kg/height/height. doi: 10.1007/s00247-008-1090-8, 131. Because the WHO growth charts are based on an international study of exclusively breastfed infants raised in optimal nutritional conditions, they are less likely to incorrectly identify breastfed infants as underweight. Many devices approved for pediatric use were not tested in a clinical trial involving children. Acta Paediatr Scand. Currently, hand and wrist X-ray is the gold standard to assess children's bone age. A bone age study helps doctors estimate the maturity of a child's skeletal system. Chronological age vs. bone age in 169 children with Cystic Fibrosis Dots under the line represented a delay in bone age. Introduction. Genetic potential is determined by mid-parental height, which is calculated by averaging sex-adjusted parental heights.Kutney shared the following examples. doi: 10.1210/jc.2006-1645, 13. Satoh M. Bone age: assessment methods and clinical applications. Obesity (Silver Spring). In 1991, Pietka et al. Midparental height growth velocity should be calculated to evaluate a child's growth vs. potential height. Human Rights: Convention on the Rights of the Child. The bibliographies of review articles and textbook chapters were also reviewed for original research articles. The normal range is represented by 2 standard deviations (SD) above and below the mean (white area on this chart). The TannerWhitehouse method was developed in 1,930 using data obtained in European children (3, 113). Awais M, Nadeem N, Husen Y, Rehman A, Beg M, Khattak YJ. Particularly, the tables are based on the assumption that there is a correlation between the proportion of adult stature reached at that time and skeletal age. Alshamrani K, Messina F, Offiah AC. Finally, the bone age (BA) is an assessment of the degree of skeletal maturation. Bone age in children of diverse ethnicity. (2000) 12:6105. (1997). Int J Androl. Br Med Bull. 7. Aissaoui A, Salem NH, Mougou M, Maatouk F, Chadly A. (2006) 22:110. The X-ray image is black and white. In fact, if a simple comparison is made, it is likely inadequate when the proximal and distal bones vary in maturation, sometimes by several years. doi: 10.2214/ajr.167.6.8956565, 97. Growth Hormone Deficiency. 104. As sex steroid levels rise during puberty, bone maturation accelerates. doi: 10.1109/42.108597, 128. If a child has bone age 10 years, it means that the child maturation is as advanced as the average of the 10-year old children from Ohio in 1930-1940 that Greulich and Pyle studied. Tanner-Whitehouse method of assessing skeletal maturity: problems and common errors. doi: 10.1111/j.1365-2265.2010.03799.x, 33. Maes M, Vandeweghe M. A valuable improvement of adult height prediction methods in short normal children. Prepubertal gynecomastia linked to lavender and tea tree oils. For infants and toddlers, weight, length, and head circumference should be plotted on a growth curve at every visit. Moreover, a deficit of thyroid hormones or an excess of corticosteroids causes a cell division reduction in the proliferation zone, inducing a growth delay. It is also common in chronic inflammatory states or infectious diseases, such as juvenile idiopathic arthritis and states of immunodeficiency (3037). Although encouraging results have been shown, this method still requires improvements in terms of reproducibility and elimination of confounding factors (135, 136). Thorne MC. Thus, gender-specific images are compared with the one obtained by patients by evaluating first the nearest chronological age and subsequently the adjacent standards. The BayleyPinneau method uses a series of tables that are indexed according to gender, chronological age, and skeletal age. GreulichPyle distinguished two standard templates: 31 and 27 radiographic images, in male and female individuals, respectively, which illustrate different phases of bone maturation between 0 and 18 or 19 years, respectively. The BoneXpert method for automated determination of skeletal maturity. (1973) 83:2336. In particular, estrogens and oral contraceptives or creams containing testosterone or estrogens can cause an early closure of the growth plate. A systematic search has been performed in PubMed to identify randomized controlled trials (RCTs), meta-analyses, and retrospective and prospective studies of different methods to evaluate bone age, focusing on strengths and weaknesses of each procedure. (2012) 46:7709. 111. Although useful and easy to use, this method might be affected by several causes of errors. They should stay still for 23 seconds so the X-ray image is clear. Standard deviation score charts of skeletal maturity and its velocity in Swedish children assessed by the Tanner-Whitehouse method (TW2-20). Bone age should be compared with chronologic age to help narrow the differential diagnosis of short or tall stature. 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. AJR Am J Roentgenol. Haffner D, Nissel R. Growth and puberty in chronic kidney disease. (10), adult height may be overestimated in constitutional delay, and at the same time, it may be underestimated in idiopathic short stature. Images of hand and wrist x-rays in four female subjects compatible with physiological skeletal maturation in different ages: A (4 years), B (8 years), C (12 years), D (16 years). Comprehensive Pediatric Nephrology. Bone age in the 21st century: is Greulich and Pyle's atlas accurate for Israeli children? Therefore, newer methods, such as artificial intelligence, might be used with the aim to guide endocrinologists and radiologists in the daily routine approach. (1982) 52:88112. I NTRODUCTION. doi: 10.1159/000184846, 130. van Rijn RR, Lequin MH, Thodberg HH. The entire procedure takes about 5 min during which 11 measuring cycles are performed. A comparison of radiation dose of two strategies for skeletal age estimation", "Bone age assessment of children using a digital hand atlas", "Traditional and New Methods of Bone Age Assessment-An Overview", "Book Review: Skeletal Maturity. J Pediatr. Bone age represents a common index utilized in pediatric radiology and endocrinology departments worldwide for the definition of skeletal maturity for medical and non-medical purpose. 91. Kulin HE, Bwibo N, Mutie D, Santner SJ. During puberty, the contours of the epiphyses begin to overlap, or cap, the metaphyses. (1998) 75:4929. It is administered through daily injections over several years. doi: 10.1007/s00414-008-0237-3, 65. Although several body areas have been studied over the years in order to define a standardized and universal method (3, 6), the wrist and knee areas represent the gold standard procedures (3, 7). [11], A drawback associated with the Greulich and Pyle method of assessing bone age is that it relies on x-ray imaging and therefore requires exposing the patient to ionizing radiation. Assessment of the carpals, metacarpals, and phalanges are used to find the closest match in the atlas; the chronological age of the patient in the atlas becomes the bone age assigned to the patient under review. J Pediatr. As well, height prediction methods might be affected by ethnicity-related differences, thus either underestimating or overestimating adult height, with wide variations in accuracy. This method has the advantage of being more reproducible, and it is not based on the subject age but on skeletal maturity of several bone elements and population-based references. Health Phys. Vignolo M, Milani S, DiBattista E, Naselli A, Mostert M, Aicardi G. Modified Greulich-Pyle, Tanner-Whitehouse, and Roche-Wainer-Thissen (knee) methods for skeletal age assessment in a group of Italian children and adolescents. doi: 10.1016/j.jflm.2013.11.011, 98.

Fortes EM, Malerba MI, Luchini PD, Sugawara EK, Sumodjo L, Ribeiro Neto LM, et al. The mean growth velocity ranges from 8 to 10 cm/year, roughly +2 to +4 SD for chronological age, and results in increased heights, between +1.5 and +2.5 SD for age on average. doi: 10.1111/j.1556-4029.2012.02294.x. Pak J Med Sci. They do this by taking a single X-ray of the left wrist, hand, and fingers. Childrens bones have areas of new bone growth called growth plates at both ends. (2010) 6:145. In addition, 11 patients with multiple scans at different ages were assessed for change in CH with age. doi: 10.1016/j.jpeds.2008.08.018, 137. As known, operator variability (intravariability) is defined by the degree of variability in the interpretation of same data performed at two different times by the same operator. For example if a girl will have a normal timed puberty and a final height of 55, she would be expected to grow along the 50th percentile through childhood. But perfectly healthy kids also can have bone ages that differ from their actual ages. Age, height, weight, BMI z-score, and BA/CA were similar in the PA and control groups . (1994) 7:1415. Samadi M, Rashid RJ, Ghaffari S, Shoaran M. Study on bone age in pediatric patients with congenital heart disease and its relation with cyanosis and pulmonary artery pressure. Other causes include renal, hepatic, and gastrointestinal diseases, and other genetic syndromes.1015, The initial evaluation of short stature (Figure 1) should include a history and physical examination, accurate growth assessment, calculation of the growth velocity and midparental height, and radiography to evaluate bone age.16 Drugs known to cause short stature include steroids (chronic use), attention-deficit/hyperactivity disorder medications, and anticonvulsants. (2003) 23:2942. Gaskin CM, Kahn SL, Bertozzi JC, Bunch PM. A person viewing it online may make one printout of the material and may use that printout only for his or her personal, non-commercial reference. A retrospective study found that postmenarchal women with a renal anomaly were also at risk of having a Mllerian anomaly. Clin Pediatr Endocrinol. Common normal variants of short stature are familial short stature, constitutional delay of growth and puberty, and idiopathic short stature. The Fels method was developed by Roche through a longitudinal study, based on a total of 13,823 serial X-rays of the left hand and wrist. Further, there can be moderate levels of variability in the bone ages assigned to the same patient by different assessors. (1992) doi: 10.1017/CBO9780511661655, 127.

Multiple regression equations for predicting the adult height of boys and girls from height and bone age at ages 4 and upwards are presented. Reliability of the methods applied to assess age minority in living subjects around 18 years old. A delayed bone age is common in malnourished conditions associated with chronic diseases such as intestinal inflammatory chronic diseases, celiac disease, and cystic fibrosis (2629). (2014) 238:8390. These include lifestyle factors such as diet, exercise, activity level and history of illness or injury. Pediatr Radiol. Dysmorphic characteristics suggest a genetic disorder, whereas midline defects suggest an abnormality of the growth hormone axis. In several conditions involving atypical growth, bone age height predictions are less accurate. Children with this condition are born appropriate for gestational age, but will then fall to the 3rd percentile for height during catch-down growth. [1][2], Bone age acts as a surrogate for physiological development because growth and maturation of the skeletal system depend on the presence of hormones like growth hormone, sex steroids (e.g., estrogen and testosterone), and thyroxine. In another study on 62 boys and 28 girls with short stature, BP method is more accurate for short boys than short girls (140).

Loder RT, Estle DT, Morrison K, Eggleston D, Fish DN, Greenfield ML, et al. The height age (HA) refers to the CA at which a child's height would be at the 50th percentile for age and sex. 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. Pituitary. (2015) 51:235. doi: 10.1111/jpc.12837, 61. Henley DV, Lipson N, Korach KS, Bloch CA. It is based on the determination of a score obtained from hand and wrist skeletal maturation. Because of this, those who are short with an advanced bone age, need medical attention before their bones fully fuse. (2015) 24:14352. 70. Acharya SV, Gopal RA, Lila A, Menon PS, Bandgar TR, Shah NS. The chronological age (CA) is the child's actual age, based on birth date. Hochberg Z. Endocrine Control of SkeletalMaturation. (1975) 64:8538. [42][43] The bones of the limbs form and lengthen through endochondral ossification beginning by the 12th week after fertilization.[41]. doi: 10.1111/j.1651-2227.2011.02476.x, 74. Puberty usually occurs early, leading to a near-normal height.19, Obese children are tall for their age.19 However, these children often have an early onset of puberty and therefore a near-normal final height.20, Intervention is usually not needed in children with tall stature. In patients with pituitary gigantism, octreotide (Sandostatin) and pegvisomant (Somavert) have been used to suppress the growth hormone.19. If the image is blurred, the X-ray technician might take another one. (2009) 28:5266. 1, Fig. (2010) 126:93844. doi: 10.1080/03014469000001142, 117. J Pediatr. The bone age at onset of puberty was 11.0 1.5 years. 114. Table 2 includes normal growth velocity by age.1,9.

[24] Since most of the ossification centers counted using this technique appear early in life, this method is only valid for measuring bone age up to around 5 years of age. 3rd ed. The bone age study can help evaluate how fast or slowly a child's skeleton is maturing, which can help doctors diagnose conditions that slow down or speed up physical growth and development. Bone age is measured in years, most often using the Greulich-Pyle scale. First the capitate forms at an average age of 2 months, followed shortly by the hamate, then the triquetrum around 14 months, and so on.[44]. This information, associated to the characterization of the shape and changes of bone components configuration, represent an important factor of the biological maturation process of a subject. Nowadays, many methods are available to evaluate bone age. Arch Dis Child. Ashizawa K, Kumakura C, Zhou X, Jin F, Cao J. RUS skeletal maturity of children in Beijing. For example, in children born small for gestational age who remain short after birth, bone age is a poor predictor of adult height.
