Brief Summary:
Bone age assessment is currently an important tool in final height implication in children. It is an important tool in the phases of investigation and treatment of short stature, tall stature, pubertal timing and various endocrinological pediatric situations. It is currently assessed using hand x-ray. This method has several limitations, including: requirement of specialized medical staff to interpret results, exposure radiation and usage of equipment which is only in radiology centers. The investigators aim to study a new equipment, radiation free, with simple and swift operation which provides an immediate answer, no need for an experienced observer, a mobile equipment with easy accessibility. The aim of the study is to assess its reproducibility, validity and safety compared to the x-ray method.
The investigators hypothesize it is as accurate and valid.

Detailed Description:
Skeletal maturity assessment, defined also as bone age (BA), has an important role in pediatrics and pediatric endocrinology, used mainly for evaluating growth and puberty related endocrine disorders. Repeated BA assessment is important during the follow up of children with short stature, with precocious puberty and those treated by growth promoting medications.
The most commonly used method used for determining skeletal maturity, and thus BA is based on comparison of a hand and wrist radiographs to a standard series of representative films in the "Radiographic atlas of skeletal development of the hand and wrist" by Greulich and Pyle (GP), which has been issued several decades ago. Among the disadvantages and drawbacks in this BA assessment method are: the obligatory need for using radiology units that are often available only in special facilities or hospitals, not available at the physicians office, the exposure to ionizing radiation, and the known limitation of the method for the need of an endocrinologist to assess the BA, with a known large inter observers variability of the BA interpretation.
The suggested method in this study is based on ultrasound technology, and therefore it is quick, objective, and radiation-free. It delivers an immediate non biased result without the need to rely on an observer's evaluation of the hand radiograph and without the need for a specialized radiology facility.
This technique was innovated in order to find an efficient, convenient and non radiation based method of skeletal maturity assessment for the primary care physician that can be performed in an office setting.
The aim of this study is to establish a correlation algorithm between the BA assessment by an ultrasound apparatus (SonicBone) and the X-ray based assessment using Grulich and Pyle method, and to evaluate the validity and reproducibility of the apparatus, The design of the study is to perform a concomitant skeletal maturation assessment by reading of a hand X-ray radiograph by 3 experienced observers using the GP method, and by the ultrasound technique using the SonicBone apparatus. Skeletal maturation assessment will be performed in females and males at various age groups.
