About this study

Patients with idiopathic scoliosis (IS), especially children and adolescents, require regular follow-up evaluations. Ultrasound imaging offers a reliable, radiation-free method for assessing spinal curvatures in the coronal and sagittal planes. While manual labeling in traditional ultrasound is error-prone, automated labeling reduces inaccuracies but still needs further validation, particularly in the sagittal plane. This study compared three-dimensional (3D) ultrasound assessments with conventional X-ray images--the clinical gold standard. And it is aimed to evaluate the validity and reliability of ultrasound measurements-Ultrasound Curve Angle (UCA) and Ultrasound Lamellar Angle (USLA)-against established radiographic benchmarks like Cobb's angle, Thoracic Kyphosis (TK), and Lumbar Lordosis (LL).

Read the detailed description

This study was structured into two fundamental segments: 1) a dual-operator analysis focused on evaluating both intra- and inter-operator reliability of the UCA and USLA; and 2) a validation study of radiographic indices, specifically the coronal Cobb angle, TK, and LL, in correlation with UCA and USLA measurements. Initially, 100 patients diagnosed with IS were subjected to both standard radiographic and 3D ultrasound examinations. Owing to various exclusion criteria, 20 patients were subsequently disqualified from the study, resulting in a final sample of 80 patients for statistical evaluation. Reliability assessments were conducted using the Intraclass Correlation Coefficient (ICC). Furthermore, the validity of the UCA and USLA measurements was rigorously analyzed by comparing them against established radiographic benchmarks, utilizing Pearson correlation coefficients and Bland-Altman plots for comprehensive evaluation. All expected or unexpected adverse events from this study will be recorded and monitored.For comprehensive analysis, participants were systematically categorized based on multiple demographic and clinical parameters: coronal angle (either ≥20° or <20°), gender (male or female), age (either>14 years or ≤14 years), and nutritional status (classified as normal or abnormal).

Questions about this trial

What is this clinical trial studying?

An observational study of Ultrasonography and Coronal, run by The First Affiliated Hospital of Zhejiang Chinese Medical University at 1 site in China.

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 2 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 19 Jul 2024. 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 China. 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?

Coronal thorax/thoracolumbar/lumbar cobb angle and sagittal thorax/thoracomaxillary/lumbar anterior and posterior lordosis angles on x-ray (time frame: January to May 2024). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 19 Jul 2024.
