Plain English Summary
Background and Study Aim:
Although surgery is the only form of treatment that provides the lasting reduction of a deformed spine (idiopathic scoliosis), it does so at the expense of spinal motion. Also, fusion done early in the adolescent growth spurt may significantly limit growth. A new treatment that provides lasting control of the curve without these limitations would be a meaningful addition to the armamentarium of surgical treatments for AIS.
This research study involves the use of an investigational medical device, called SCOLITETHER(MIScoli) System (internal bracing). The system is being developed for the treatment of idiopathic scoliosis (scoliosis for which the cause is unknown), to reduce deformity and prevent its worsening in growing children/adolescents at high risk for curve progression while preserving motion. The SCOLIOTETHER system uses screws to attach to the spine’s bone growth on the curved side so that as your child grows the curve may stop progressing or improve. The SCOLITETHER system was used only in a group of five female subjects in a clinical pilot study conducted in Singapore and it was observed that the use of this system to address idiopathic thoracic scoliosis was effective and safe. It is not available for use by doctors because it is not yet approved for use. Health Canada has reviewed and approved the use of the SCOLITETHER system in this clinical trial.
Who Can Participate?
Children from the age of 8 years old to 13 years old with idiopathic scoliosis who still has some more growing
What does the study involve?
The purpose of this clinical study is to demonstrate that the SCOLITETHER system is safe for use and shows probable benefit by stopping the progression of the major curve (Cobb angle) of a scoliosis in growing children and adolescents when compared to their initial curvature.
What are the possible benefits and risks of participating?
Any research study has potential risks. The medical device and the surgery may have risks and cause discomfort and inconveniences, some of which may be unknown at this time.
The SCOLITETHER system might potentially avoid the need for fusion surgery resulting in a greater range of motion and more flexibility. Fusion surgery usually involves an open back incision compared to the small incisions with the SCOLITETHER system surgery. This leads to a much shorter recovery time. There may be less risk of infection, less blood loss, and so less need for blood transfusion, increase range of motion and less pain with the SCOLITETHER system.
When is the study starting and how long is it expected to run for?
March 2019 to March 2020.
Where is the study run from?
The study is being held in 4 different locations throughout Canada.
1. Sainte-Justine Hospital in Montreal, Quebec
2. The Montreal Children’s Hospital in Montreal, Quebec
3. The Children’s Hospital of Eastern Ontario in Ottawa, Ontario
4. British Columbia’s Children’s Hospital in Vancouver, BC

Study hypothesis
The SCOLI-TETHER system shows benefit to halt the progression of the major curve of scoliosis reflected by a decrease in the Cobb angle compared to baseline.

Condition
Major thoracic scoliosis with Cobb Angle greater than 40° and Lenke I, II and V curve pattern.
Intervention
The SCOLI-TETHER (MIScoli) System is intended for anterolateral vertebral body fixation and internal fastening of the convex side of the thoracic curvatures thereby reducing the deformity and preventing the progression of idiopathic scoliosis in growing children/adolescents at high risk for curve progression while preserving motion. This device is intended for use in patients 8-13 years of age who have a major thoracic scoliosis with Cobb Angle greater than 40° and Lenke I, II and V curve pattern. It is intended to be used at contiguous levels through an anterior thoracoscopic or open technique between T4 and L2 inclusively. The device is intended to treat major thoracic scoliosis in patients who have less than 50° of thoracic kyphosis (T5-T12) and a Risser stage of 0 or 1.
X-rays will be taken to monitor the progress from baseline to 5-year follow-up. The x-ray will take place at the participant’s local participating hospital and reviewed by an independent laboratory different from the hosptial
