A Prospective Analysis of Long-Term Clinical Outcomes and 3D Spine Growth in Anterior Vertebral Body Tethering
NCT04914507 · View on ClinicalTrials.gov ↗
Study Summary
Anterior vertebral body tethering (AVBT) is a novel, minimally invasive, growth modulation technique that was recently approved by the FDA under a Humanitarian Device Exemption (HDE). The goal of AVBT is to control curve progression by applying compression on the convex side of the spine deformity. While there has been great initial enthusiasm about the technique as an alternate treatment option to spinal fusion for skeletally immature children with scoliosis, there is a need to better understand the long-term outcomes. The purpose of this study is to report the long-term clinical outcomes of skeletally immature patients treated with AVBT, specifically: 1. The effect on three-dimensional spine growth as compared to normal controls 2. Maintenance of major Cobb angle less than or equal to 50 degrees at skeletal maturity 3. Complications associated with both the procedure and the device

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT04914507
The ClinicalTrials.gov registry entry for NCT04914507 describes a study currently listed as recruiting. It is categorized as NA, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 106 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Pediatric Spine Foundation, which has 29 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Scoliosis Idiopathic appearing as the primary indexed condition, and to 1 intervention — of which Anterior Vertebral Body Tethering is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT04914507 reports 12 study locations spanning 12 distinct geographic areas — top geographies include District of Columbia, Illinois, Minnesota. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
