What this trial studies

This study aims to evaluate the effectiveness of a radiation-free ultrasound system for screening scoliosis among female school children in Hong Kong. The primary goal is to determine if this ultrasound method can accurately identify children with a Cobb angle greater than 20°, thereby reducing unnecessary x-ray exposure. Additionally, the study will assess whether the Angle of Trunk Rotation (ATR) can enhance the accuracy of ultrasound assessments. This approach seeks to improve the scoliosis screening protocol by minimizing radiation risks associated with traditional x-ray examinations.

Who should consider this trial

Good fit: Ideal candidates for this study are female school children in Hong Kong who are part of the Student Health Service screening program and are recommended for radiographic assessment.

Not a fit: Patients who may not benefit from this study include those with certain physical conditions, such as a BMI of 25 kg/m2 or higher, or those with skin diseases or spinal irregularities that affect ultrasound scanning.

Why it matters

Potential benefit: If successful, this study could significantly reduce unnecessary x-ray exposure for school children while maintaining effective scoliosis screening.

How similar studies have performed: Other studies have shown promise in using ultrasound for scoliosis screening, but this specific approach is relatively novel in the context of reducing x-ray exposure.
