Sunlight BonAge is a unique ultrasound-based sonometer that currently offers the only way to test bone age in children and adolescents aged 5 – 18 years without exposing them to ionizing x-ray radiation.

Skeletal age testing, sometimes known as bone age assessment, provides more information about the developmental status of a child than can be inferred from his/her height, weight, and age alone. Results serve to identify growth patterns and growth deficiencies for pediatric patients.

There is a pressing need for non-x-ray testing of skeletal age because at least 5% of children aged 5-18 are affected by short stature and/or growth abnormalities and such children are routinely tested for skeletal maturity to track their growth development. In addition, many others are tested to identify growth patterns and deficiencies. Standard testing involves x-ray measurement of the patient’s left hand, and is usually performed once or twice each year for those under growth supervision.

Accurate Results, Immediately

With x-ray-free BonAge, pediatric skeletal age testing can be done in the physician’s office. This eliminates the need to send patients to outside clinics for testing and avoids time delays between consultation and diagnosis, enabling any necessary treatment or follow-up to begin sooner.

BonAge measures the ossifying cartilage structures of the wrist, which provide an excellent window into skeletal development and reliable prediction of adult height. Radiation-free, safe and objective, as well as easy to use, it provides on-the-spot, easy-to-read results in years and months based on the widely accepted Greulich and Pyle method.

The BonAge Advantage

• Proven safety
  • Radiation-free
  • Unique ultrasound-based technology
• Objective
  • Automated operation
  • Operator-independent bone age score
• High precision
  • Numeric bone age results based on gender- and ethnicity-based algorithm
  • Results highly correlated with Greulich and Pyle method
  • Reliable adult-height prediction
• Physician & patient-friendly
  • Fast measurement
  • Easy to read results in years and months, displayed in full-color graphical format
  • Well-child growth monitoring tools included
• In-office testing
  • Eliminates need to refer patients to external testing facilities
• Added value
  • Incorporates a growth module for gender-based and ethnicity-based follow-up and adult final height prediction
  • Optional bone density assessment package

Unique Ultrasound-based Technology

Sunlight BonAge measures bone parameters at the wrist to pro­vide an estimation of bone maturity. The device measures the Speed-of-Sound (SOS) and the distance between the transducers. During measurement, ultrasonic waves are passed through the patient’s growth plate on the left wrist via attached transducers. This measurement site, which includes centers of ossification that change with growth, is the same site used to formulate the x-ray plates in the Greulich and Pyle (G&P) Atlas.

BonAge is not a standalone device. It should be installed on the Sunlight Omnisense 7000/ Omnisense 8000 bone sonometer.

In the United States, the BonAge device is available for research use only.
