About this trial

This is an interventional treatment trial for Scoliosis focused on measuring Scoliosis, Spine deformity, Brace, Growth modulation

Eligibility Criteria

10 Years - 16 Years (Child)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • AIS diagnosis
  • Risser 0-2
  • Primary curve angles 20 degrees - 40 degrees
  • If female, either premenarchal or less than 18 months postmenarchal.

Exclusion Criteria:

  • Patients with a pre-existing cardiovascular condition
  • Patients with a symptom of a neurological disorder
  • Patients with any other disorder of the musculoskeletal system affecting the lower limbs

Sites / Locations

  • CHU Sainte-Justine

Arms of the Study

Arm 1

Arm 2

Arm Type

Experimental

Active Comparator

Arm Label

Test group: Braces designed with growth modulation simulation

Control group: Conventional method

Arm Description

The braces will be designed using a growth modulation method.

The braces will be designed by an orthotist without growth modulation simulation.

Outcomes

Primary Outcome Measures

Change in Cobb angle
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.

Secondary Outcome Measures

Treatment failure rate
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
Quality of Life (QoL)
The QoL will be measured using the SRS-22r and MOBI questionnaire.
Immediate in-brace Cobb angle
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. Study Description

Brief Summary
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.

Interventional Study Model
Parallel Assignment
Model Description
The study will be separated into two stages. Each patient will initially try a control brace and a test brace in a crossover study model to evaluate the immediate correction. Each patient will then use one brace from either the control arm or test arm to evaluate the long-term correction of the brace.

8. Arms, Groups, and Interventions

Arm Title
Test group: Braces designed with growth modulation simulation
Arm Type
Experimental
Arm Description
The braces will be designed using a growth modulation method.
Arm Title
Control group: Conventional method
Arm Type
Active Comparator
Arm Description
The braces will be designed by an orthotist without growth modulation simulation.
Intervention Type
Device
Intervention Name(s)
Test brace versus control brace: Immediate correction
Intervention Description
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.
Intervention Type
Device
Intervention Name(s)
Test brace versus control brace: Long-term correction
Intervention Description
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.
