Bone age is the degree of maturation of a child's bones. As a person grows from fetal life through childhood, puberty , and finishes growth as a young adult, the bones of the skeleton change in size and shape.

Metrics details. Skeletal age SA is considered the best method of assessing biological maturation. The aim of this study was to determine intra-observer reproducibility and inter-observer agreement of SA values obtained via the Greulich-Pyle GP method. In addition, the variation in calculated SAs by alternative GP protocols was examined.

DOI: As an indicator of growth rate, bone age is used to determine the level of development and to predict chronological age when this is not known. The mean difference between the bone and chronological ages was 0. Given the systematic errors with regard to the reference population, we propose the adjustment required to apply the ages calculated according to the atlas and indicate the limitations inherent to predicting chronological age when only information from the bones in the hand and wrist is used. The technological, social and political upheavals of the past few years have modified lifestyles, revolutionised economies and caused the downfall of numerous companies and the emergence of many others in light of the new business opportunities created.
The main bone age assessment methods are the Greulich-Pyle and Tanner-Whitehouse 2 methods, both of which involve left hand and wrist radiographs. Several other bone age assessment methods have been developed, including ultrasonographic, computerized, and magnetic resonance MR imaging methods. The ultrasonographic method appears unreliable in children with delayed and advanced bone age. MR imaging is noninvasive; however, bone age assessment using MR imaging is relatively new, and further examinations are needed. An automated method for determining bone age, named BoneXpert, has been validated for Caucasian children with growth disorders and children of various ethnic groups. Sex hormones are necessary for bone growth and maturation in children with a bone age corresponding to normal pubertal age, and estrogen is essential for growth plate closure. Bone age is an effective indicator for diagnosing and treating various diseases.
Is the Greulich and Pyle atlas applicable to all ethnicities? A systematic review and meta-analysis
It seems that you're in Germany. We have a dedicated site for Germany. Authors: Gilsanz , Vicente, Ratib , Osman. In the past, determination of bone maturity relied on visual evaluation of skeletal development in the hand and wrist, most commonly using the Greulich and Pyle atlas. The Gilsanz and Ratib digital atlas takes advantage of digital imaging and provides a more effective and objective approach to assessment of skeletal maturity. This easy-to-use atlas and the related App will be invaluable for radiologists, endocrinologists, and pediatricians and also relevant to forensic physicians.
Nov Taskforces. It might be unknown or intentionally falsified e. However, most commonly, age determination is needed for young asylum seekers. Every year, young unaccompanied asylum seekers arrive in European countries, many without knowing how old they are or unable to provide formal documentation of their age. To ensure that children receive their rights and that adults are not treated as children, it is necessary to assign a chronological age to these individuals. Evaluation of skeletal maturation of the hand development has been used for age assessment of asylum seekers in many countries. The method has been criticized for its lack of precision.
Quality of the studies was assessed using the National Institute for Health and Care Excellence tool. Meta-analysis used mean differences and standard deviations as summary statistics for the difference between bone age BA and chronological age CA. Of the 49 eligible studies, 35 were appropriate for further meta-analysis. The online version of this article Determining maturity and understanding growth in a child is critical for medical and psychosocial purposes. Assessing bone age is important to investigate whether the maturity of bones is occurring at the same rate as the chronological ageing process. For example, in asylum seekers and unaccompanied minors without valid documents to prove their ages [ 1 ], it is important to assess bone age using a reliable and suitable method [ 2 ].
5 Software User Manual. Bone age assessment is frequently performed in pediatric patients to evaluate growth and to diagnose and manage a Underlying the construction of the Greulich and Pyle atlas are the assumptions that, in healthy.

Evaluation of the bone age in years old children in Manaus-AM city. The beginning and the peak of the pubertal growth spurt occurred earlier among girls Early maturation was more frequent among girls than among boys Mean bone age in the group of boys was Keywords: Growth and development.
In the past, determination of bone maturity relied on visual evaluation of skeletal development in the hand and wrist, most commonly using the Greulich and Pyle atlas. The Gilsanz and Ratib digital atlas takes advantage of digital imaging and provides a more effective and objective approach to assessment of skeletal maturity. The atlas integrates the key morphological features of ossification in the bones of the hand and wrist and provides idealized, sex- and age-specific images of skeletal development. Bone Age enables users to rapidly browse through the set of idealized atlas images and select the one that best matches the image being interpreted.
С какой стати университетский профессор… Это не университетские дела. Я позвоню и все объясню. Мне в самом деле пора идти, они связи, обещаю. - Дэвид! - крикнула .
На полу возле тела Хейла лежал листок бумаги. Сьюзан наклонилась и подняла. Это было письмо. Дорогие друзья, сегодня я свожу счеты с жизнью, не в силах вынести тяжести своих грехов… Не веря своим глазам, Сьюзан медленно читала предсмертную записку.
Но было что-то. Сьюзан на мгновение заколебалась и оглянулась на заблокированную дверь. Всего двадцать минут, подумала. Повернувшись к терминалу Хейла, Сьюзан вдруг уловила странный мускусный запах - очень необычный для Третьего узла. Она подумала, что дело, быть может, в неисправном ионизаторе воздуха.
