About this study
In the scoliosis screening program of the Student Health Service (SHS), Department of Health (DH), in Hong Kong, more than 50% of screened school children prescribed with x-ray examination basing on the screening protocol did not have Cobb angle greater than the referral threshold of 20°; ie they did not need specialist referral and thus were subjected to unnecessary x-ray exposure. Our primary objective is to determine whether a new radiation-free ultrasound system could identify subjects with Cobb angle greater than the referral threshold of 20° thus avoiding unnecessary x-rays in the referral workflow. The secondary objective is to evaluate if Angle of Trunk Rotation (ATR) can further increase the accuracy of ultrasound assessment.
This study is an extension of the registered project entitled "Using Radiation-free Ultrasound for Screening Scoliosis Among School Children in Hong Kong to Reduce Unnecessary X-ray Exposure", (ClinicalTrials.gov Identifier: NCT03135665), however focusing on validity of ultrasound measurement for immature female subjects aged around ten with year since menarche equal to or less than 9 months, who are prone to curve progression, and thus are among the most critical group in clinical management of scoliosis for regular monitoring, treatment decision, and brace indication.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Ultrasound (Scolioscan system), and EOS radiography systemDevice
Scolioscan ultrasound system was reported to be reliable and valid for spinal deformity assessment. The system composes of an ultrasound scanner with a linear probe of 10 cm width and frequency range of 4-10MHz, a frame structure and a spatial sensor attached to the ultrasound probe for spatial data capture. Daily calibration will be performed using phantom to assure accuracy of spine image formation and subsequent angle measurement. Subjects will stand on the Scolioscan platform with a standardized posture kept stable with pegs throughout the scanning process. The probe will be steered from L5 to C7 spinous process for scanning. SPA will be used to determine the ultrasound-based Referral Status through predicting whether the Cobb angle is beyond the referral threshold of ≥20° or not. There are two values for the Referral Status: either "for specialist referral" or "not for specialist referral". Coronal Cobb angle measurement on EOS radiographs will be used as gold standard.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
In the scoliosis screening program of the Student Health Service (SHS), Department of Health (DH), in Hong Kong, more than 50% of screened school children prescribed with x-ray examination basing on the screening protocol did not have Cobb angle greater than the referral threshold of 20°; ie they did not need specialist referral and thus were subjected to unnecessary x-ray exposure. Our primary objective is to determine whether a new radiation-free ultrasound system could identify subjects with Cobb angle greater than the referral threshold of 20° thus avoiding unnecessary x-rays in the referral workflow. The secondary objective is to evaluate if Angle of Trunk Rotation (ATR) can further increase the accuracy of ultrasound assessment.
This study is an extension of the registered project entitled "Using Radiation-free Ultrasound for Screening Scoliosis Among School Children in Hong Kong to Reduce Unnecessary X-ray Exposure", (ClinicalTrials.gov Identifier: NCT03135665), however focusing on validity of ultrasound measurement for immature female subjects aged around ten with year since menarche equal to or less than 9 months, who are prone to curve progression, and thus are among the most critical group in clinical management of scoliosis for regular monitoring, treatment decision, and brace indication.

Questions about this trial
What is this clinical trial studying?
A study testing Ultrasound (Scolioscan system), and EOS radiography system in people with Scoliosis and Spinal Curvatures, run by Chinese University of Hong Kong at 1 site in Hong Kong.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 31 Mar 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Hong Kong. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
ultrasound-based Referral Status (time frame: Baseline). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT06828068, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 31 Mar 2026.
