Brief summary

This is a study to collect data in a controlled manner on the use of the MAGEC Spinal Bracing and Distraction System in patients with Adolescent Idiopathic Scoliosis (AIS) who have failed external bracing therapy.

Interventions

The Ellipse MAGEC Spinal Bracing and Distraction System is comprised of a sterile single use spinal rod that is surgically implanted using appropriate commercially available fixations components (i.e. pedicle screws, hooks, and/or connectors). The system includes a non-sterile hand held External Remote Controller that is used at various times after implant to non-invasively lengthen or shorten the implanted spinal rod. The implanted spinal rod is used to brace the spine during growth to minimi

The Ellipse MAGEC Spinal Bracing and Distraction System is comprised of a sterile single use spinal rod that is surgically implanted using appropriate commercially available fixations components (i.e. pedicle screws, hooks, and/or connectors). The system includes a non-sterile hand held External Remote Controller that is used at various times after implant to non-invasively lengthen or shorten the implanted spinal rod. The implanted spinal rod is used to brace the spine during growth to minimize the progression of scoliosis. The rod includes a small internal magnet which allows the rod to be lengthened by use of the External Remote Controller. The MAGEC device is approved for commercial use in New Zealand and also is CE-marked. The duration of the implant procedure is approximately 1.5 - 2.5 hours, depending on the surgeon's preferred construct. The duration the device remains in place is prescribed by the physician and differs per patient. The device may remain in the patient for up to 5 years.
