Validation of a New Generation of Orthopedic Brace for Treating Adolescent Idiopathic Scoliosis by Using Growth Modulation

May 11, 2021 updated by: Hubert Labelle, MD, St. Justine's Hospital
Adolescent Idiopathic Scoliosis affects 3-4% of the Canadian population, of which about 10% will need a brace treatment during pubertal growth spurt. Our team has developed an innovative conception method for brace design by simulating the growth modulation using numerical models. Those models are customized to each patient. In this project, the investigators will evaluate the effectiveness of this platform customized treatment and validate its clinical application.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Test group: Braces designed with growth modulation simulation
The braces will be designed using a growth modulation method.
Device: Test brace versus control brace: Immediate correction
The trunk surface will be scanned to reconstruct a numerical model of the patient's trunk, this reconstruction will help to produce the optimized brace. The patient skeletal will also be reconstructed from a bilateral radiograph using an EOS imaging system. Each patient will try both the control and the test brace. Radiographic and patient-reported data will be gathered and analyzed to observe changes between the immediate correction of the braces. The SRS-22r will be collected. The study protocol requires no additional visits beyond the standard of care. There will be one additional radiograph compared to the standard of care.
Device: Test brace versus control brace: Long-term correction
After comparing the immediate correction of the braces, each patient will be using either the test or the control brace for a period of two years. There will be follow-up visits, between 6 months and 1 year depending on the patient growth. The brace will be renewed using the same procedure to adapt to the patient's growth. The study protocol requires no additional visits beyond the standard of care. There will be no additional radiograph compared to the standard of care. Compliance monitors are installed in each brace.
Active Comparator: Control group: Conventional method
The braces will be designed by an orthotist without growth modulation simulation.
Device: Test brace versus control brace: Immediate correction
The trunk surface will be scanned to reconstruct a numerical model of the patient's trunk, this reconstruction will help to produce the optimized brace. The patient skeletal will also be reconstructed from a bilateral radiograph using an EOS imaging system. Each patient will try both the control and the test brace. Radiographic and patient-reported data will be gathered and analyzed to observe changes between the immediate correction of the braces. The SRS-22r will be collected.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Cobb angle
Time Frame: Baseline - 2 years
Radiographics will be gathered and analyzed to observe changes between time points. All radiographs will be taken with an low-dose biplane radiographic system (EOS) to allow 3D reconstructions.
Baseline - 2 years

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Treatment failure rate
Time Frame: Baseline, 2 years
Treatment failure is defined as having a Cobb angle progress by more than 5 degrees compared to the baseline measurement or exceeding a value of 45 degrees
Baseline, 2 years
Quality of Life (QoL)
Time Frame: Baseline, 2 years
The QoL will be measured using the SRS-22r and MOBI questionnaire.
Baseline, 2 years
Immediate in-brace Cobb angle
Time Frame: 5 minutes after brace fitting
Radiographics will be gathered and analyzed to observe changes between the control and test braces. All radiographs will be taken with an low-dose biplane radiographic system (EOS).
5 minutes after brace fitting
