Conclusion: (N=144) The BAUSport TM system provides a reasonable non-invasive indicator of skeletal maturity that is moderately associated with percentage of predicted adult height derived from the Khamis-Roche method.


2021 – Barca validation study: BAUSport by Sonicbone against Skeletal Age assessment using the Fels, G&P, & TW2 and x-ray based methods

Conclusion: (N=86, Under peer review) The study findings support the use of BAUSport as an alternative, practical and non-invasive methods for the estimation of SA in young athletes. In comparison to the established methods for estimating SA in youth, the BAUSport system performed well and especially in the categorization of youth as advanced, on-time, and delayed in maturation.


2020 –  “Biological Maturity Status in Elite Youth Soccer Players: A Comparison of Pragmatic Diagnostics with Magnetic Resonance Imaging”

Conclusion: The results suggest that the use of SAUS, (BAUSport) MOMIR, and PAHKR for measuring BMS is more pragmatic in terms of cost and time as compared with MRI diagnostics. Based on a general agreement between these pragmatic diagnostics and the reference method MRI in all three perspectives, the alternative methods can be used to determine BMS among (male) elite youth soccer players


2020 -“Bone Age Assessment in Children Using Ultrasound Compared to Hand X-ray (G&P method)”

Conclusion: (N=260, Intermediate results) – Bone Age estimated by BAUSport™ is substantially equivalent to physicians’ Bone Age estimates, for both males and females

  • Under peer review


2020 – “Evaluation of the BAUSport System (By Sonicbone) for Assessing Skeletal Age in Youth”

Conclusion: “In comparison to existing methods, the BAUSport method serves as an equally valid and reliable (if not more) measure of skeletal age (as determined by the Fels x-ray based method)”.

Conclusion: (N=494) “There is a significant positive correlation between BAUS and BARx. BAUS is a safe and practical method of bone age determination, with potential clinical applicability”.


2017 – Conclusion: (N=150) “Bone age assessment by SonicBone is comparable to the assessment by X-ray based methods”.


2017 – “Evaluating Bone Age and Predicting Young Athletes’ Final Height by a Novel Ultrasound Device (Sonicbone’s BAUSportTM) and their Applications to Talent Selection, Training and Sports Medicine.

APCST 2017- the 8th Asia-Pacific Congress on Sports Technology – Tel Aviv, Oct 15 – 19, 2017) Abstract:

Conclusions: “BAUSportTM can serve as a routine tool for implementation of more scientifically-based programs for training and injury prevention in youth athletes, with better talents selection process for various sports”.

Conclusion: (N=450)Shorter and thinner pubertal but not pre-pubertal children have delayed BA as compared to taller and heavier children. ii) The full-length phalanx maturation is affected by height more than the wrist and metacarpals’ epiphyses. iii) The radius-ulna epiphyses are affected by BMI more than the metacarpals and phalanx. iv) These influences have now on to be accounted for in the assessment of a BA.” 


2015 – “On the need for national, racial, or ethnic-specific standards for the assessment of bone maturation“. 

Prof. Ze’ev Hochberg, MD PhD, Eur J Endocrinol. 2015 Sep 28. pii – EJE-15-0673

Conclusion: The notion that genes are the primary determinants of physiognomy, which also includes growth-related traits, has been repeatedly disproved. Based on a fundamental understanding of phenotypic plasticity and an individual’s ability to respond to environmental cues, we do not need ethnic-specific standards for bone maturity.
