What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.

Summary

This study looked at two types of surgery for teens with scoliosis (a curved spine). One method, called vertebral body tethering (VBT), uses a flexible cord to straighten the spine while allowing more natural movement. The other, posterior spinal fusion (PSF), permanently fuses the bones together. Researchers compared how well each corrected the curve and how much spine flexibility was preserved over time. The goal was to see which approach offers better long-term function and safety.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Patients diagnosed with adolescent idiopathic scoliosis who underwent surgical correction using posterior spinal fusion or vertebral body tethering from 2019 to 2022 and provided informed consent; * Males or females aged 12 to 18 years at the time of surgery; * Sanders skeletal maturation age ≤ 6; * Thoracic scoliotic curve ≥ 40° COBB and ≤ 60° COBB, measured on upright full spine x-rays, anterior-posterior pose. Exclusion Criteria: * Patients who had previously undergone spinal or thoracic surgery prior to adolescent idiopathic scoliosis correction; * Surgically treated patients with scoliosis of a non-idiopathic etiology; * Patients with anamnestic, clinical, and radiographic characteristics that do not fall within the indication window for the surgical technique of vertebral body tethering; * Patients with severe intramedullary malformations (syringomyelia greater than 4 mm, Chiari malformation, or tethered cord); * Structured scoliotic lumbar curve \> 35°, as measured by Cobb radiography. * Patients who do not provide informed consent to the study.
