Idiopathic short stature is defined as a height less than two standard deviations below the mean for age without a known etiology. Pediatr Radiol. 68. Cox LA. Although several bones have been studied to better define bone age, the hand and wrist X-rays are the most used images. 102. [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. Int J Pediatr Endocrinol.

[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. 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). 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. The X-ray image is black and white. 135. Tanner-Whitehouse method of assessing skeletal maturity: problems and common errors. Your body age is a measure of how healthy and typical your physical condition is compared to what is expected for your chronological age. doi: 10.3348/kjr.2015.16.1.201, 100. In fact, bone age can provide important information for athletes in order to distribute physical, human, and monetary resources properly (6567).

(2012) 101:47. Infants born small for gestational age typically have catch-up growth in the first 24 months, but 10% have a final height more than two standard deviations below the mean for age.24 Children who do not have catch-up growth within the first six months or whose height is not within two standard deviations of the mean for age by two years of age may have a pathologic condition.
