ClinConnect Summary

This clinical trial is studying a new way to screen for scoliosis, which is a condition where the spine curves abnormally. Instead of using X-rays, which can expose children to radiation, the researchers want to see if a special ultrasound system can safely identify girls who need further evaluation for scoliosis. The focus is on young female students around the age of ten who are at risk for scoliosis progression and may need more regular monitoring or treatment.

To be eligible for the trial, participants must be school-aged girls in Hong Kong who are part of a scoliosis screening program and have had their first menstrual period for no more than nine months. Girls who have certain health issues or conditions that could interfere with the ultrasound exam, like skin diseases or recent surgeries, will not be included. Those who participate can expect a safe and non-invasive ultrasound procedure, which is a quick and painless way to assess their spine without the risks associated with X-rays. This study aims to make scoliosis screening safer and more effective for young girls.
