doi: 10.1210/jc.2008-2474, 133. 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. 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. Therefore, newer methods, such as artificial intelligence, might be used with the aim to guide endocrinologists and radiologists in the daily routine approach. Dense body parts, such as bones, block the passage of the X-ray beam through the body. Most children with short stature have normal variants such as familial short stature, constitutional delay of growth and puberty, or idiopathic short stature. ( p =0.67). The initial evaluation of short and tall stature should include a history and physical examination, accurate serial measurements, and determination of growth velocity, midparental height, and bone age. Images provided by The Nemours Foundation, iStock, Getty Images, Veer, Shutterstock, and Clipart.com. This content is owned by the AAFP. This test is usually ordered by pediatricians or pediatric endocrinologists. Therefore, carpal bones are not ossified at birth, and this process typically advances from the center of ossification (80). These include lifestyle factors such as diet, exercise, activity level and history of illness or injury. This chart depicts bone age as compared with chronological age in boys. The bone age at onset of puberty was 11.0 1.5 years. Those with an advanced bone age typically hit a growth spurt early on but stop growing at an earlier age. Growth Hormone Deficiency. After puberty, all carpals, metacarpals, and phalanges are completely developed, their physes are closed, and the assessment of skeletal maturity is based on the degree of epiphyseal fusion of the ulna and radius (8082). 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. On this Wikipedia the language links are at the top of the page across from the article title. Cushing's syndrome in children and adolescents. Prediction of adult height by Tanner-Whitehouse method in young Caucasian male athletes. [35], An advanced or delayed bone age does not always indicate disease or "pathologic" growth. Bull RK, Edwards PD, Kemp PM, Fry S, Hughes IA. (2001). doi: 10.1016/S0022-3476(52)80205-7, 138. In addition, subjects with long-lasting and untreated growth hormone (GH) deficiency have a delay in bone maturation. Pinchi V, De Luca F, Ricciardi F, Focardi M, Piredda V, Mazzeo E, et al. [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. Int J Paediatr Dent. Vignolo M, Naselli A, Magliano P, Di Battista E, Aicardi M, Aicardi G. Use of the new US90 standards for TW-RUS skeletal maturity scores in youths from the Italian population. J Paediatr Child Health. X-rays are commonly done in doctors offices, radiology departments, imaging centers, and dentists offices. The effects of long-term medication on growth in children and adolescents with ADHD: an observational study of a large cohort of real-life patients. As sex steroid levels rise during puberty, bone maturation accelerates. Tanner JM. 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. Tall stature is defined as a height more than two standard deviations above the mean for age (greater than the 97th percentile). [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. In some circumstances bone age is informative but usually it is not. doi: 10.1515/jpem-2015-0234, 38. In fact, bone age can provide important information for athletes in order to distribute physical, human, and monetary resources properly (6567). Aust Orthod J. doi: 10.1016/S0022-3476(97)90000-7, 8. (1998) 13:5007. A difference between a child's bone age and their chronological age might indicate a growth problem. 5. Tanner-Whitehouse method of assessing skeletal maturity: problems and common errors. Table 3 includes the differential diagnosis of short stature.1,2,4,1618, If the initial evaluation suggests a genetic, endocrine, or gastrointestinal disorder, laboratory testing should be performed (Table 4).1,3,13,14,16,19,20 In an asymptomatic child with short stature, an evaluation of the growth curve may provide clues to the underlying pathology. For patients two to 20 years of age, weight, height, and body mass index should be plotted. As well, height prediction methods might be affected by ethnicity-related differences, thus either underestimating or overestimating adult height, with wide variations in accuracy. Issues and advances in adolescent growth and development. 3. A score is assigned to each bone based on maturation and sex of the patient. It is also common in chronic inflammatory states or infectious diseases, such as juvenile idiopathic arthritis and states of immunodeficiency (3037). These changes can be seen by x-ray and other imaging techniques. The child's hand/ wrist X-ray is interpreted based on the appearance . There is a separate equation for each half year of chronological age; and for pre- and postmenarcheal girls at ages 11 to 14. Statistics have been compiled to indicate the percentage of height growth remaining at a given bone age. doi: 10.1055/s-2000-3766, 89. A table of possible causes of abnormal stature and the expected bone age associated with each condition is provided below. Data obtained by hand and wrist radiography during bone age assessment are also used in many nonmedical fields for example in sports (64) and for national policy in many countries (10). [1][14][23], The bones in the hand a wrist in a newborn do not change much in the first year of life. 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. doi: 10.1016/S0022-3476(95)70347-0, 12. doi: 10.1002/ajpa.1330180309, 81. 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 . (2017) 37:1925. 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. (1983). 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. The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest.

In this way, a maturity score is obtained for each area of clinical interest, generally categorized as A, B, C, D, E, F, G, H, and I. This system does not take into account the state of carpus bones maturation and allows a bone age assessment between 2.5 and 17 years and 2.0 and 15.0 years for male and female individuals, respectively. CRAIG BARSTOW, MD, AND CAITLYN RERUCHA, MD. Am J Dis Child. Then, the remaining centers progressively appear (Figure 1) (80). This information, associated with the characterization of the shape and changes of bones, represents an important factor of the biological maturation process. A survey on a Moroccan origin population. Obesity (Silver Spring). The BayleyPinneau method uses a series of tables that are indexed according to gender, chronological age, and skeletal age. Leg Med. Performing bone age assessments can assist clinicians in diagnosing central precocious puberty. Sweden Begins New Asylum Seeker Age Assessment Tests. [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. (2006) 91:420514. So the confidence interval around the chronological age estimated from bone age is 30 months (i.e. Author disclosure: No relevant financial affiliations. A child with GHD may have a bone age that is much less than his/her chronological age. The main advantage of this procedure related to the evaluation of each bone segment, thus minimizing the interoperator variability. J Clin Endocrinol Metab. Pak J Med Sci. doi: 10.1016/j.gcb.2008.09.020, 30. . Insulinlike growth factor has been used in children with insulinlike growth factor deficiency. Bone age assessments can provide pediatricians with a rough estimate of when a child will enter puberty, Kutney stated. Conclusion: Bone age calculated by Greulich & Pyle Atlas should not be used for estimating chronological age in children of ages 56-113 months in situations where high accuracy is required (e.g. De Sanctis V, Soliman AT, Di Maio S, Bedair S. Are the new automated methods for bone age estimation advantageous over the manual approaches? Participants with missing data on covariates (28% of those potentially eligible) were excluded from the analyses. Pediatr Endocrinol Rev. Available from: Constitutional delay in growth and development, "Infant bone age estimation based on fibular shaft length: model development and clinical validation", "Bone age assessment practices in infants and older children among Society for Pediatric Radiology members", "Bone age: assessment methods and clinical applications", "Is the use of the cervical vertebrae maturation method justified to determine skeletal age? [16][22] The TW methods consist of evaluating individual bones and assigning a letter grade to each bone based on its degree of maturation. This evaluation is more detailed than a simple comparison and takes into consideration a detailed analysis of structural characteristics of different bones with the assignment of a score to each element (3, 113, 114). A comparison between the appearance of a patient's bones to a standard set of bone images known to be representative of the average bone shape and size for a given age can be used to assign a "bone age" to the patient. The diagnosis can be made by a decreased insulinlike growth factor 1 or insulinlike growth factor binding protein 3, followed by negative growth hormone provocation test results.23, Small for Gestational Age. Thodberg HH, Kreiborg S, Juul A, Pedersen KD. (2005) 154:312. Sperlich M. Final height and predicted height in boys with untreated constitutional growth delay. They add length and width to the bone. The Khamis-Roche Method predicts adult stature, without determining the bone age. (2016) 170:16370. Using multivariate linear regression analysis, we determined the relationship of CH to age, sex, and HL type. This material may not otherwise be downloaded, copied, printed, stored, transmitted or reproduced in any medium, whether now known or later invented, except as authorized in writing by the AAFP. Since bone age measurements are inherently approximations, they are conventionally reported with a standard deviation which serves as an estimate of the associated error. All authors contributed to manuscript revision and read and approved the submitted version. The applicability of Greulich and Pyle atlas to assess skeletal age for four ethnic groups. Extensive clinical experience: nonclassical 21-hydroxylase deficiency. Endocr Rev. Short or tall parents may themselves have a pathologic reason for their height, especially if they are more than two standard deviations from the adult norm.68, Growth velocity is a measurement of growth rate. Discrepancies between bone age and biological age can be seen in people with stunted growth, where bone age may be less than biological age. doi: 10.1359/jbmr.1998.13.3.500. Bone age is the degree of a person's skeletal development. doi: 10.1093/bmb/lds014. 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. 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 . Acta Paediatr Scand. There are extremes to be mindful of, Kutney added. A longitudinal study. The test also can help doctors monitor progress and guide treatment of kids with conditions that affect growth, including: If you have questions about the bone age X-ray or what the results mean, talk to your doctor.

Over the years, this system has been refinished by moving from an initial system known as TannerWhitehouse method 1 (TW1) to two subsequent methods known as TannerWhitehouse 2 (TW2) and 3 (TW3) (3, 113, 114). Gilsanz RO. An X-ray of the left hand and wrist will measure your child's bone age. Introduction. doi: 10.1007/BF02171555, 116. 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. Crowne EC, Shalet SM, Wallace WH, Eminson DM, Price DA. Automatic determination of Greulich and Pyle bone age in healthy Dutch children.

[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. (2016) 52:5238. doi: 10.1111/j.1365-2265.2010.03799.x, 33. It uses age, gender, child height and weight, mother height, and father height. doi: 10.3923/pjbs.2009.702.706. It is also possible to evaluate a physiological variant of familial early puberty (14), especially in some ethnic groups (15, 16).
