Assessment of a patient's bone age is used in pediatric medicine to help determine if a child is growing normally. Thus, the variability in the bone age at onset of puberty was greater than the variability in the chronological age at onset of puberty ( Fig. doi: 10.1159/000101336, 25. Comprehensive Pediatric Nephrology. The height age (HA) refers to the CA at which a child's height would be at the 50th percentile for age and sex. Bone age for chronological age determination - statement of the European Society of Paediatric Radiology musculoskeletal task force group Bone age for chronological age determination - statement of the European Society of Paediatric Radiology musculoskeletal task force group Authors Although several bones have been studied to better define bone age, the hand and wrist X-rays are the most used images. Mora S, Boechat MI, Pietka E, Huang HK, Gilsanz V. Skeletal age determinations in children of European and African descent: applicability of the Greulich and Pyle standards. doi: 10.1097/MPG.0b013e31818cb4b6, 32. a systematic review and meta-analysis. 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. The emergence of the primary ossification centers of the carpal bones appear in a predictable order that can help in determining bone age. Horm Res. The BayleyPinneau method uses a series of tables that are indexed according to gender, chronological age, and skeletal age. International Olympic Committee consensus statement on thermoregulatory and altitude challenges for high-level athletes. J Pediatr. Most children will achieve a final height within 4 inches of the mid-parental height estimate, she said. Prediction of adult height by Tanner-Whitehouse method in young Caucasian male athletes. Child Adolesc Psychiatry Ment Health. Bass S, Pearce G, Bradney M, Hendrich E, Delmas PD, Harding A, et al. doi: 10.1016/j.jflm.2013.11.011, 98. Calculating the midparental height (Table 1) is an important part of the evaluation because most short or tall children have short or tall parents. For children with idiopathic short stature, four years of treatment results in an increased height of 3.7 cm (1.46 in) and costs between $100,000 and $120,000.25,26, Oxandrolone (Oxandrin) is an oral anabolic steroid that has been shown to increase height velocity but has little effect on final height. (10), adult height may be overestimated in constitutional delay, and at the same time, it may be underestimated in idiopathic short stature. doi: 10.1080/03014460500087725, 119. (2007) 356:47985. The most common measurement standards used for bone age are the Greulich and Pyle Atlas 2 and the Tanner-Whitehouse 3 assessments. (1984) 73:5306. Although this method is very accurate and allows doctors to estimate children's bone age even when they are <1 year old, the Fels method is too complex, thus minimizing its daily use. Many devices approved for pediatric use were not tested in a clinical trial involving children. Presentation, diagnosis, and therapy. 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). The keywords for the research have been bone age and skeletal maturation.. Copyright 2021 Cavallo, Mohn, Chiarelli and Giannini. Ranjitkar S, Lin NH, Macdonald R, Taylor JA, Townsend GC. Herman TE, Crawford JD, Cleveland RH, Kushner DC. (1994) 7:1415. Every 6-12 months, height and bone age should be assessed. Bassett JH, Williams GR. (1987) 8:4708. 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. [41] The cells of the mesenchyme can become bone by one of two primary methods: (1) intramembranous ossification where mesenchymal cells differentiate directly into bone or (2) endochondral ossification where mesenchymal cells become a cartilaginous model of chondrocytes which then become 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. However, there are several caveats to the diagnosis of constitutional delay of growth. Standard deviation score charts of skeletal maturity and its velocity in Swedish children assessed by the Tanner-Whitehouse method (TW2-20). Malina RM, Rogol AD, Cumming SP, Coelho e Silva MJ, Figueiredo AJ. [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. If bone age reading is performed with the TannerWhitehouse method, there are some equations proposed by Tanner to calculate growth prognosis (10, 122, 123). (2000) 12:6105. Using multivariate linear regression analysis, we determined the relationship of CH to age, sex, and HL type. doi: 10.1259/0007-1285-67-801-848, 95. Fortes EM, Malerba MI, Luchini PD, Sugawara EK, Sumodjo L, Ribeiro Neto LM, et al. 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). Note: All information on KidsHealth is for educational purposes only. These systems use different algorithms; thus, no standardized and universally accepted indexes have been proposed so far (130, 131). There is a chart for males and another for females with possible bone ages ranging from 1 month to 5 years. (2016) 52:5238. doi: 10.1056/NEJMra021561, 54. Growth at Adolescence. This determination is based on the presence of particular centers of bone formation as well as the dimension and structure of the bones (3, 58). - average male height Boys come into puberty later than girls. (1997) 24:25761. [7][8][16], The two most common techniques for estimating bone age are based on a posterior-anterior x-ray of a patient's left hand, fingers, and wrist. doi: 10.1515/jpem.2010.138, 63. doi: 10.4158/EP13193.OR, 52. (2015) 173:63342. It is also possible to evaluate a physiological variant of familial early puberty (14), especially in some ethnic groups (15, 16). Am J Dis Child. Radiographic evaluation of skeletal maturation. 3. Obesity (Silver Spring). J Bone Miner Res. doi: 10.1111/j.1365-2605.2005.00575.x, 17. 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. However, data obtained from the assessment of bone age can be widely used both in medical or nonmedical settings. [11][7] One common method based on x-rays of the hemiskeleton is the Sontag method. However, she will stop growing earlier than her peers to attain a final adult height at the 50th percentile, Kutney noted. To note, usually the first ossification center to appear is in the contest of Capitate and Hamate at the second month in females and around the fourth month in males. doi: 10.1097/MPG.0000000000000848, 57. Bone growth estimation using radiology (GreulichPyle and Tanner-Whitehouse Methods). The determination of bone age is important to properly assess and guide the evaluation of short or tall stature, impaired or accelerated growth, and delayed or early puberty (10). doi: 10.1111/j.1556-4029.2012.02294.x. Evaluation may also be needed in a child who has a normal height, but a projected height more than two standard deviations from the midparental height. (2005) 32:31625. Each bone segment begins its maturation first in the primary ossification center and then, through different stages of enlargement and remodeling, reaches the final shape; many bones, like long bones, have many centers of maturation (epiphysis). 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.

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. Oxford University Press (2011). [7][8] Here, a selection of bones are given a score based on their perceived development, a sum is totaled based on the individual bone scores, and the sum is correlated to a final bone age. (2007) 92:3712. Bol Med Hosp Infant Mex. 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). They add length and width to the bone. 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. Tall stature is defined as a height more than two standard deviations above the mean for age (greater than the 97th percentile). Alshamrani K, Messina F, Offiah AC. then every 6 months. Clin Pediatr Endocrinol. Age Determination Procedures for Custody Decisions. Chronological age versus bone age for boys. 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. Springfield, IL: Charles C. Thomas. chronological and bone age for each sex and age group, the equality of the mean for each age was compared (Student's t-test for paired It is based on a computerized system obtained from a series of measurements provided by a large reference population. doi: 10.1159/000184848. The applicability of the Greulich & Pyle Atlas for bone age assessment in primary school-going children of Karachi, Pakistan. [30][31][32][33][34], There are exceptions with people who have an advanced bone age (bone age is older than chronological age) due to being an early bloomer (someone starting puberty and hitting PHV earlier than average), being an early bloomer with precocious puberty, or having another condition. For infants and toddlers, weight, length, and head circumference should be plotted on a growth curve at every visit. There are extremes to be mindful of, Kutney added. Discrepancies between bone age and biological age can be seen in people with stunted growth, where bone age may be less than biological age. Greulich WW. doi: 10.1016/S0022-3476(95)70347-0, 12. doi: 10.1515/jpem-2015-0234, 38. (1983). 114. Bone age should be compared with chronologic age to help narrow the differential diagnosis of short or tall stature. doi: 10.1016/j.forsciint.2014.02.030. 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. In patients with pituitary gigantism, octreotide (Sandostatin) and pegvisomant (Somavert) have been used to suppress the growth hormone.19. Katherine Kutney, MD, a pediatric endocrinologist at Rainbow Babies and Childrens Hospital in Cleveland, Ohio, said bone age assessments are typically done with an x-ray of the left hand. (1978) 93:74955. Gaskin CM, Kahn SL, Bertozzi JC, Bunch PM. (2014) 238:8390. J Forensic Dent Sci. In fact, the bone maturation process lasts longer in male than in female individuals (8385), and the moment of closure of the epiphyseal region occurs is roughly 2 years earlier in girls than in boys. doi: 10.1258/ar.2012.120443, 122. Soegiharto BM, Cunningham SJ, Moles DR. Skeletal maturation in Indonesian and white children assessed with hand-wrist and cervical vertebrae methods. Congenital adrenal hyperplasia. Statistics have been compiled to indicate the percentage of height growth remaining at a given bone age. Effective dose and energy imparted in diagnostic radiology. So the confidence interval around the chronological age estimated from bone age is 30 months (i.e. Angle Orthod. Medical, statistical, ethical and human rights considerations in the assessment of age in children and young people subject to immigration control. The probe is made up of two portions: the first one that emits radiofrequencies (750 kHz) that are directed against the surface of ulna and the radio epithelium and the second probe that receives radiofrequencies. Similarly, an excessive intake of foods containing phytoestrogens such as soya, according to some studies, may have an effect on bone age progression (5663). doi: 10.1136/adc.68.5.677, 37. [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.

CG has written sections of the manuscript. J Forensic Dent Sci. 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). The bone ages of hand and elbow were different at puberty, and the elbow was a more reliable location for bone-age assessment at puberty. (2006) 29:2416; discussion 8690. Huda W, Gkanatsios NA. Advanced bone age and hyperinsulinemia in overweight and obese children. doi: 10.1093/ajcn/36.3.527, 27. 103. The use of bone age in clinical practice - part 1. Underweight in a child with short stature suggests a systemic illness or malnutrition, whereas overweight suggests an endocrine disorder.2,21, Different causes of short stature tend to fall within identifiable growth patterns, and a review of a child's growth curve and bone age should guide further evaluation. 2nd ed. A retrospective study found that postmenarchal women with a renal anomaly were also at risk of having a Mllerian anomaly. Spec Care Dentist. Automatic determination of Greulich and Pyle bone age in healthy Dutch children. Assessments of skeletal maturity in prepubertal children are primarily based on the epiphyseal size of the phalanges as they relate to the adjacent metaphyses. It uses age, gender, child height and weight, mother height, and father height. (1999) 51:16872. doi: 10.3348/kjr.2015.16.1.201, 100. [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. Midparental height growth velocity should be calculated to evaluate a child's growth vs. potential height. (1989) 1:493494. Treatments alter the natural progression of SMA. The long-term effects of protein energy malnutrition in early childhood on bone age, bone cortical thickness and height. 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. Eur J Paediatr Dent. Reference standards for this method were published in 1950 and 1960; however, from these initial publications, several studies have shown a shift toward an earlier bone maturation process in the general population worldwide (16). There are also exceptions with people who have a delayed bone age (bone age is younger than chronological age) due to being a late bloomer (someone starting puberty and hitting PHV later than average), being a late bloomer with delayed puberty, or having another condition. Insulinlike growth factor has been used in children with insulinlike growth factor deficiency. 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. For this reason, pediatricians should evaluate patients on the bases of all the available knowledge about the child, particularly their personal growth history. 3rd ed. Furthermore, the GP method has not been updated from its initial publication, representing important limits of applications especially in some ethnic groups such as African or Hispanic female subjects and in Asian and Hispanic male subjects during late infancy and adolescence (95, 96). doi: 10.1097/YIC.0000000000000109, 44. Bone age is delayed if it is below this threshold (blue area), and advanced if it is above this threshold (green area). Short stature is defined as a height more than two standard deviations below the mean for age (less than the 3rd percentile). Roche AF, Rohmann CG, French NY, Davila GH. To note, a proper assessment of bone age must always take into account differences between ethnic groups, sex, and any present pathological conditions. Idiopathic short stature is defined as a height less than two standard deviations below the mean for age without a known etiology. [11][7] Alternative techniques for estimating bone age in infancy include tallying the number of ossification centers present in the left half of the infant's body requiring a hemiskeleton x-ray. Assessment of bone age is often required during international immigration programs (68, 69). Am J Hum Biol. doi: 10.1016/j.forsciint.2007.02.023. (2013) 54:10249. Several authors have proposed different algorithms for predicting adult height. Assessment of skeletal age at the wrist in children with a new ultrasound device. doi: 10.1007/s00247-019-04435-z. Consequently, when a naturally short child has an advanced bone age, it stunts their growth at an early age leaving them even shorter than they would have been. (2012) 223:372 e14. Linklater A, Hewitt JK. (2014) 20:627. 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. FCa has written the first draft of the manuscript. [2][5], To assign a bone age to the patient under review, a radiologist compares the patient's hand and wrist x-ray to images in the Greulich and Pyle atlas. 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. Congenital hypothyroidism leads to growth arrest, delayed bone age, and short stature at birth. Bones and growth plates change over time. (2007) 173:14653. Pediatr Endocrinol Rev. 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. Between 1931 and 1942, Greulich and Pyle evaluated the hand and wrist radiographs obtained from about 1,000 white people of Cleveland (Ohio, USA) belonging to mediumhigh social classes (9, 10, 106). 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.
