Assessment of bone age in prepubertal healthy Korean children: comparison among the Korean standard bone age chart, Greulich-Pyle method, and Tanner-Whitehouse method. These systems use different algorithms; thus, no standardized and universally accepted indexes have been proposed so far (130, 131). Viii + 339 pp. doi: 10.1590/S1806-83242005000300010, 36. doi: 10.1016/0197-0070(87)90048-9, 84. [] The other applications of BA include height prediction and estimation of age in children seeking asylum in other countries and in competitive sports where chronological age (CA) may be unknown. The bibliographies of review articles and textbook chapters were also reviewed for original research articles. 111. This system of prediction is based on the fact that skeletal age correlates with a specific percentage of mature height reached in a specific moment when chronological age is constant. All authors contributed to manuscript revision and read and approved the submitted version. doi: 10.1006/clim.2000.4838, 35. Satoh M. Bone age: assessment methods and clinical applications. Thus, some authors suggest that, whenever possible, the same method should be used, favoring TW2 method if possible (93). [1][2][21], The Tanner-Whitehouse (TW) technique of estimating bone is a "single-bone method" based on an x-ray image of a patient's left hand and wrist. 4.

The entire procedure takes about 5 min during which 11 measuring cycles are performed. 104. March 12, 2021. In the case of too much growth hormone, a child may have a bone age that is older than their chronological age suggesting that they are growing abnormally fast. Biological maturation of youth athletes: assessment and implications. These tables, the Bayley-Pinneau tables, are included as an appendix in the Greulich and Pyle atlas. 5. Bone age is distinct from an individual's biological or chronological age, which is the amount of time that has elapsed since birth. In several conditions involving atypical growth, bone age height predictions are less accurate. BMJ Case Rep. (2015) 2015:bcr2015212216. Clin Pediatr Endocrinol. (1999) 51:16872.

To note, growth patterns may be influenced by relevant and common confounding factors and particularly illnesses, diet, and hormone imbalances. Growth and development: congenital adrenal hyperplasia-glucocorticoids and height. The following are generally documented (84, 97105): a delay in bone age in Middle-Eastern men and Iranian men and in Southeast Asian children (Indonesian and Indian men and women) and Asian-American men; an advanced age in Afro-American children (more in female than in male) and in Middle Eastern female children (Iranian girls); no variation is documented for Italian, Korean, and Scottish children and in Pakistani girls. 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. According to a recent study, the BoneXpert method is affected by obesity to a lesser extent than the GreulichPyle method. An appraisal of Greulich-Pyle Atlas for skeletal age assessment in Pakistan. doi: 10.1093/med/9780199782055.001.0001, 10. Using an atlas-based method gives a great possibility of intra- and interoperator variability (142). (TW 2 method). Instead, the variability among different operators (intervariability) is defined by the degree of variability in the interpretation of same data made by two different operators at the same time.

Assessment of bone age is also important for the correct diagnosis, particularly with the aim of detecting the causes of bone age alteration including mainly endocrine and nutritional causes and chronic nonendocrine disorders and syndromes. A survey on a Moroccan origin population. [3] However, most pediatric radiologists still use the Greulich and Pyle technique for estimating bone age in infancy. (2014) 24:88993. doi: 10.1258/ar.2012.120443, 122. Separate tables are used for boys and girls because of the sex difference in timing of puberty, and slightly different percentages are used for children with unusually advanced or delayed bone maturation. Bone maturation along the spectrum from normal weight to obesity: a complex interplay of sex, growth factors and weight gain. Karger editor. 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. In particular, these prediction tables are developed from the GreulichPyle standards for hands, thus with the expectation that they will be used in conjunction with these standards (137, 138). Inflamm Bowel Dis. doi: 10.1016/S0022-3476(95)70347-0, 12. Eur J Endocrinol. They can be seen on an X-ray because they're softer and contain less mineral, making them appear darker on an X-ray image than the rest of the bone. Although most children with short or tall stature do not have a pathologic condition, extremes of height, especially beyond three standard deviations, require further workup. doi: 10.1093/qjmed/hcs230, 66. doi: 10.1159/000185511, 141. It is based on a computerized system obtained from a series of measurements provided by a large reference population. Loder RT, Estle DT, Morrison K, Eggleston D, Fish DN, Greenfield ML, et al. | Do we take RSV disease seriously enough? Children with cardiac diseases, or those with chronic kidney or liver disease, may experience a delay in skeletal maturation (3842). 69. Figure 2 is an algorithm for the evaluation of tall stature.19 Although the percentage of children with tall stature is equal to that of children with short stature, children with tall stature are much less likely to be referred to subspecialty care. Pinchi V, De Luca F, Ricciardi F, Focardi M, Piredda V, Mazzeo E, et al. In 2008, a new fully automated system was introduced, known as BoneXpert (Visiana, Denmark), with a reading time between 1.5 and 4 min. (10), adult height may be overestimated in constitutional delay, and at the same time, it may be underestimated in idiopathic short stature.

A bone age study helps doctors estimate the maturity of a child's skeletal system. This was followed by a comparison between the skeletal age estimates and the chronological ages of the patients. [3][21], Images in the Greulich and Pyle atlas came from healthy white boys and girls enrolled in the Brush Foundation Study for Human Growth and Development between the years 1931 and 1942. doi: 10.1038/nrendo.2009.242, 53. Acharya SV, Gopal RA, Lila A, Menon PS, Bandgar TR, Shah NS. These tables have been formulated on bone age assessment according to the standards of Greulich and Pyle.

(2009) 94:223944. AJR Am J Roentgenol. J Pediatr Gastroenterol Nutr. The BoneXpert method for automated determination of skeletal maturity. 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. [15] An alternative approach to the atlas method just described is the so-called "single-bone method" where maturity scales are assigned to individual bones. [citation needed], An advanced bone age is common when a child has had prolonged elevation of sex steroid levels, as in precocious puberty or congenital adrenal hyperplasia. Rosemont, IL: American Academy of Orthopaedic Surgeons (2000). Leg Med. (1995) 154:627. doi: 10.1007/BF02079065, 142. No use, distribution or reproduction is permitted which does not comply with these terms. p. 70932. doi: 10.1016/j.jpeds.2008.08.018, 137. Conversely, bone age may be normal in some conditions of abnormal growth. 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. Thorne MC. A distance of 76 cm from the box tube is recommend. [2], In the United States, bone age is usually determined by comparing an x-ray of the patient's left hand and wrist to a set of reference images contained in the Greulich and Pyle atlas. ( p =0.67). 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. 112. Horm Res. As these cartilaginous zones become obliterated, the epiphyses are said to be "closed" and no further lengthening of the bones will occur. Premature thelarche in the setting of high lavender oil exposure. (2015) 51:235. doi: 10.1111/jpc.12837, 61. Henley DV, Lipson N, Korach KS, Bloch CA.

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. Therefore, during the procedure, the standard that seems similar is initially chosen, and then, the examination of each bone segment in an ordered sequence is performed by assigning the corresponding bone age to the individual segments, according to the instructions contained in the atlas text. Horm Res Paediatr. Furthermore, the impact of being overweight or obese on bone age could be identified correctly by BoneExpert.

Therefore, chronological age differs from bone age, so the two indexes need to be distinguished: chronological age is defined as the age in years between birth and the evaluation of a subject; bone age is defined by the age expressed in years that corresponds to the level of maturation of bones. doi: 10.1002/ajhb.1310010206, 126. Likewise, some pathological clinical diseases such as ovarian tumors, Leydig cells or germ cells, as well as adrenal tumors or adrenal diseases (e.g., congenital adrenal hyperplasia) (5255) are typically associated with excessive production of pubertal hormones that cause a rapid progression of bone age, thus advanced bone maturation. Mentzel HJ, Vilser C, Eulenstein M, Schwartz T, Vogt S, Bottcher J, et al. They look darker on the image. a systematic review and meta-analysis. Arends NJ, Boonstra VH, Mulder PG, Odink RJ, Stokvis-Brantsma WH, Rongen-Westerlaken C, et al. Skeletal Development of the Hand and Wrist: A Radiographis Atlas and Digital Bone Age Companion. Bone age is an interpretation of skeletal maturity. Puberty onset according to elbow occurred slightly earlier than expected. http://www.who.int/childgrowth/standards/en/. 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. (2010) 2010:298937. doi: 10.1186/1687-9856-2010-298937, 56. Most children will achieve a final height within 4 inches of the mid-parental height estimate, she said. Bone age is measured in years, most often using the Greulich-Pyle scale. 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. Results: At the time of diagnosis, the chronological age was 9.90.6 years, the bone age was 11.61.0 years, and the bone age/chronological age ratio was 1.200.1. Med Pediatr Oncol. [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. (1994) 7:1415. [3] In certain instances, abnormal growth conditions may be treated with supplemental hormone therapy. Constitutional delay of growth and puberty is one of the most common causes of delayed bone age (10). doi: 10.1007/s00247-019-04435-z. 47. Introduction. In the last 20 years, newer methods have also been studied with the principal aim to mainly eliminate the variability related to interpretation according to the different methods. 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. Constitutional delay of growth and pubertal development. Forensic Sci Int. Haffner D, Nissel R. Growth and puberty in chronic kidney disease. Those with an advanced bone age typically hit a growth spurt early on but stop growing at an earlier age. These characteristics are mainly documented in large cartilaginous centers, such as the head of the femur, head of humerus, and the tarsal navicular bone and are known as stippled epiphyseal dysgenesis. As sex steroid levels rise during puberty, bone maturation accelerates. [4] Other uses of bone age measurements include assisting in the diagnosis of medical conditions affecting children, such as constitutional growth delay, precocious puberty, thyroid dysfunction, growth hormone deficiency, and other causes of abnormally short or tall stature. Crowne EC, Shalet SM, Wallace WH, Eminson DM, Price DA. Similarly, an excessive intake of foods containing phytoestrogens such as soya, according to some studies, may have an effect on bone age progression (5663). Hogler W, Baumann U, Kelly D. Growth and bone health in chronic liver disease and following liver transplantation in children. A growth velocity that is less than normal should prompt further investigation. Meet the Board: Vivian P. Hernandez-Trujillo, MD, FAAP, FAAAAI, FACAAI. Then, the remaining centers progressively appear (Figure 1) (80). doi: 10.1111/j.1365-2605.2005.00575.x, 17.

[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. However, this system has some limits that must be considered, in particular, the absence of carpal bones evaluation, the opposition of local administrations to install the software, and the higher cost compared to available methods (GP and TW) (134). Recent data on pubertal milestones in United States children: the secular trend toward earlier development. A bone age study helps doctors estimate the maturity of a child's skeletal system.

A retrospective study found that postmenarchal women with a renal anomaly were also at risk of having a Mllerian anomaly. J Clin Endocrinol Metab. Bone age may be affected by several factors, including gender, nutrition, as well as metabolic, genetic, and social factors and either acute and chronic pathologies especially hormone alteration. Anink J, Nusman CM, van Suijlekom-Smit LW, van Rijn RR, Maas M, van Rossum MA. 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. doi: 10.1007/s00247-011-2302-1. (2010) 6:145. If bone age reading is performed with the TannerWhitehouse method, there are some equations proposed by Tanner to calculate growth prognosis (10, 122, 123). 109. doi: 10.1002/mpo.2950210104, 40. The Local. Skeletal maturation in children with Cushing syndrome is not consistently delayed: the role of corticotropin, obesity, and steroid hormones, and the effect of surgical cure. If findings from the initial evaluation do not suggest a diagnosis, laboratory testing may be performed (Table 4).1,3,13,14,16,19,20 A retrospective study found that a complete laboratory evaluation of an asymptomatic child with idiopathic short stature is low yield and expensive. Steps in the methodology: a Measurements of the metacarpal lengths and the M2-M5 width.b Linear regression analysis of each measured variable with chronological age.c Equations established for each model along with R 2. d Linear regression analysis of chronological age with each estimated bone age.e Intraclass correlation between the different metacarpal-based estimated bone ages and the two .

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). 5 to 5.5 cm (2 to 2.2 in) Pubertal growth spurt. 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. (1988) 77:15460. [3] Large differences between a person's bone age and their chronological age may indicate a growth disorder. Tanner-Whitehouse method of assessing skeletal maturity: problems and common errors. This means that a girl who will have a final adult height of 55 but will undergo puberty earlier than average may grow along the 80th percentile in early childhood. Available online at: https://www.rch.org.au/immigranthealth/clinical/Birth_date_issues/. History and physical examination findings should guide further evaluation for pathologic causes of short and tall stature. They do this by taking a single X-ray of the left wrist, hand, and fingers. Briers PJ, Hoorweg J, Stanfield JP. Hassel &Farman (1995)[27] developed an index based on the second, third, and fourth cervical vertebrae (C2, C3, C4) and proved that atlas maturation was highly correlated with skeletal maturation of the hand-wrist. Constitutional Delay of Growth and Puberty. [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. (2011) 76:19. doi: 10.1111/jpc.13114, 75. In fact, in the beginning, data were obtained from Caucasian children, so it is easy to understand that results assessed by the GP and TW standards are strongly dependent on ethnic group. doi: 10.1016/j.ajodo.2006.07.037, 99. Conclusions: Hormonal effects associated with adiposity and sexual maturity likely influence skeletal maturation. In addition, children with PA appeared to be affected by a BA . 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. Treatment of the various types of spinal muscular atrophy with approved therapies resulted in an array of improvements, according to a review of 22 studies. This may be inherited. (1989) 1:493494. N Engl J Med. doi: 10.1159/000053086, 49. Bone age assessment: automated techniques coming of age? 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.

The main advantage of this procedure related to the evaluation of each bone segment, thus minimizing the interoperator variability. (2009) 58:38290. There is a separate equation for each half year of chronological age; and for pre- and postmenarcheal girls at ages 11 to 14. A longitudinal study. Topor LS, Feldman H. Variation in methods of predicting adult height for children with idiopathic short stature. This lack of precision impacts on the value of bone age as evidence . Tanner-Whitehouse method of assessing skeletal maturity: problems and common errors. De Moraes ME, Tanaka JL, de Moraes LC, Filho EM, de Melo Castilho JC. In children, bone age serves as a measure of physiological maturity and aids in the diagnosis of growth abnormalities, endocrine disorders, and other medical conditions. (1995) 126:54550. For example, according to Martin et al. Typically, children with this condition have a delayed bone age with a preserved or increased weight for age. [24], Lamparski (1972)[25] used the cervical vertebrae and found them to be as reliable and valid as the hand-wrist area for assessing skeletal age. Patel PS, Chaudhary AR, Dudhia BB, Bhatia PV, Soni NC, Jani YV. [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. Numerous scales have been produced that can convert bone maturity score into bone age for different European and non-European populations (7, 114119). The BayleyPinneau method uses a series of tables that are indexed according to gender, chronological age, and skeletal age. Recent studies show that organs like the liver can also be used to estimate age and sex, because of the unique feature of liver. These methods differ according to the technique of the procedure and particularly to peculiar advantages and disadvantages (Table 1). (2015) 9:50. doi: 10.1186/s13034-015-0082-3, 45. Contemporary Pediatrics sat down with one of our newest editorial advisory board members: Vivian P.

Med Phys. He developed a series of standards for the assessment of skeletal age for both males and females. [12] The Greulich and Pyle atlas contains x-ray images of the left hands and wrists of different children deemed to be good models of the average appearance of the bones of the hand at a given age. 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). https://en.wikipedia.org/w/index.php?title=Bone_age&oldid=1141264025, Short description is different from Wikidata, Articles with unsourced statements from May 2020, Creative Commons Attribution-ShareAlike License 3.0, This page was last edited on 24 February 2023, at 05:16. 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). doi: 10.1136/adc.2005.090134, 121.
