Tanner JM, Gibbons RD. 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. A table of possible causes of abnormal stature and the expected bone age associated with each condition is provided below. Bone age assessment: automated techniques coming of age? 90. Pediatr Res. Eur J Pediatr. 5. Currently, hand and wrist X-ray is the gold standard to assess children's bone age. Assessments of skeletal maturity in prepubertal children are primarily based on the epiphyseal size of the phalanges as they relate to the adjacent metaphyses. Pituitary. A fuller description of the use of bone age films from the University of Utrecht. (1997). 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. Those with an advanced bone age typically hit a growth spurt early on but stop growing at an earlier age. [7][8] Features of bone development assessed in determining bone age include the presence of bones (have certain bones ossified yet), the size and shape of bones, the amount of mineralization (also called ossification), and the degree of fusion between the epiphyses and metaphyses. Since bone age measurements are inherently approximations, they are conventionally reported with a standard deviation which serves as an estimate of the associated error. *Correspondence: Cosimo Giannini, cosimogiannini@hotmail.it, Debates in Clinical Management in Pediatric Endocrinology, View all 29. Bone age is delayed if it is below this threshold (blue area), and advanced if it is above this threshold (green area). doi: 10.1210/jc.2008-2474, 133. Bone age is measured in years, most often using the Greulich-Pyle scale. Constitutional delay of growth and pubertal development. In addition, biology and genetics can play a part . A child whose growth is initially normal but then falls progressively further off the growth curve may have growth hormone deficiency. 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. | 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, | Update in Pediatric COVID-19 Vaccines, https://kidshealth.org/en/parents/xray-bone-age.html.

Conventionally, this clinical condition is defined by the presence of delayed bone age (at least 2 SD) compared to chronological age associated with short stature, a delay in both pubertal maturation, as well as in the achievement of adult height, compared to peers. They do this by taking a single X-ray of the left wrist, hand, and fingers. Am J Phys Anthropol. (2005) 154:312. . For patients two to 20 years of age, weight, height, and body mass index should be plotted. Peters CJ, Ahmed ML, Storr HL, Davies KM, Martin LJ, Allgrove J, et al. 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. 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). doi: 10.1016/j.jpeds.2013.11.065, 23. 3. Participants with missing data on covariates (28% of those potentially eligible) were excluded from the analyses. [29] A girl has reached 99% of her adult height at a bone age of 15 years and has a small amount of height growth left from this point on. doi: 10.3109/03014460.2015.1032349, PubMed Abstract | CrossRef Full Text | Google Scholar, 2. JAMA Pediatr. For infants and toddlers, weight, length, and head circumference should be plotted on a growth curve at every visit. Med Phys. Bone Age and Maturity in Association with Anthropometric Measurements (2010) 126:93844. (2013) 54:10249. (2014) 30:40911. Bone age assessment can be of utmost importance in various complicated situations involving medical, surgical, forensic, and legal issues. A numerical value is then assigned to each stage with specific differences between gender. It is based on the determination of a score obtained from hand and wrist skeletal maturation. Heyman R, Guggenbuhl P, Corbel A, Bridoux-Henno L, Tourtelier Y, Balencon-Morival M, et al. Bone growth estimation using radiology (GreulichPyle and Tanner-Whitehouse Methods). Tables are provided for ages 718 years. doi: 10.1210/er.2015-1106, 20. Not only can bone age help in diagnosing a child with a growth abnormality, but it can also play a role in treatment. (1996) 45 Suppl 2:535. Midparental height growth velocity should be calculated to evaluate a child's growth vs. potential height. (2010) 73:2208. 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). (2009) 28:5266. (1999) 81:1723. (1983). J Pediatr. The bones on the X-ray image are compared with X-ray images in a standard atlas of bone development. 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. (1987) 8:4708. US Immigration and Customs Enforcement, Office of Detention and Removal Operations, US Department of Homeland Security. 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. X-ray exam: bone age study. 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). 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). Thus, the liver can be employed in special medico-legal cases of skeletal deformities or mutilation. 7. 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. Moradi M, Sirous M, Morovatti P. The reliability of skeletal age determination in an Iranian sample using Greulich and Pyle method. Ossification centers are defective, appearing in an irregular and mottled pattern, with multiple foci that coalesce to give a porous or fragmented appearance. Aust Orthod J. Hjern A, Brendler-Lindqvist M, Norredam M. Age assessment of young asylum seekers. Because children grow in spurts, two measurements at least three to six months apart, and preferably six to 12 months apart, are needed to accurately determine growth velocity.4. However, the GP method requires a continuous and long experience in order to optimize bone age determination. Similarly, an excessive intake of foods containing phytoestrogens such as soya, according to some studies, may have an effect on bone age progression (5663). Prepubertal gynecomastia linked to lavender and tea tree oils. New MI. The bibliographies of review articles and textbook chapters were also reviewed for original research articles. By evaluating the data obtained from bone age in the clinical setting, it is possible to distinguish three main groups of subjects: patients with delayed bone age, patients with bone age appropriate to chronological age, and patients with advanced bone age (3, 810). (1998) 13:5007. The bone age will determine the maturity of your child's bones, compared to your child's chronological (actual or "birthday") age.

Cambridge. Bone age assessments: What they can tell you about growth 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. Correlation of bone age, dental age, and chronological age in survivors of childhood acute lymphoblastic leukaemia. doi: 10.3923/pjbs.2009.702.706. Several endocrine diseases might induce changes in bone age (10). Evaluation of Short and Tall Stature in Children | AAFP In 2008, a new fully automated system was introduced, known as BoneXpert (Visiana, Denmark), with a reading time between 1.5 and 4 min. 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. 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). N Engl J Med. Br J Sports Med. J Paediatr Child Health. 112. For this reason, pediatricians should evaluate each prediction of future height on the bases of all the available knowledge about the child, particularly their personal growth history. (1998) 49:3740. It is also common in chronic inflammatory states or infectious diseases, such as juvenile idiopathic arthritis and states of immunodeficiency (3037). doi: 10.1542/peds.2009-3649, 140. London: Academic Press (1983). Role of thyroid hormones in skeletal development and bone maintenance. Evaluation of Short and Tall Stature in Children | AAFP Although the Khamis-Roche method is considered an accurate predictor, it is not as accurate as methods using the bone age. Variability in the order of ossification of the bony centers of the hand and wrist. (2006) 22:4758. are guided by the child's expected growth.
