The MAGEC® System

The MAGEC® System for Treating Early Onset Scoliosis (EOS)

 

Early onset scoliosis (EOS) affects skeletally immature patients less than 10 years of age with severe, progressive, spinal deformities. The treatment goal is to halt the progression of the deformity while allowing for continued growth of the child (specifically, thoracic cavity height). If the thoracic cavity height is not restored, patients can experience lifelong pulmonary and cardiovascular complications.

The traditional surgical treatment for patients with moderate to severe cases of EOS requires an initial surgery, typically between the ages of five and seven. A growing rod is implanted as an internal brace to halt the deformity, and the patients undergo additional planned distraction surgeries every six months, allowing for continued growth during treatment. Sometimes these distraction surgeries can total to an additional 14 procedures beyond the initial surgery.

Beyond the concern of the cost of numerous surgical procedures, repetitive distraction surgeries are associated with psychological distress that the patient and family may experience during treatment, and increases the patients’ risks surrounding exposure to anesthesia and postoperative infections.

 

A New, Less Invasive Option

 

Magec.pngNuVasive®, along with key opinion leaders in pediatric spinal deformity, recognized the need for an alternative form of EOS treatment – the MAGEC system. MAGEC offers a significantly less invasive surgical option for patients being treated for EOS and thoracic insufficiency syndrome (TIS).

MAGEC eliminates the need for a series of invasive distraction surgeries, while still allowing for patient growth throughout treatment. With the MAGEC system, planned distractions take place in an office setting at the cost of a regular office visit. These noninvasive distractions are quick, painless, and the child can return to normal activity right away. MAGEC distractions are carried out until a patient has matured enough to undergo a final fusion procedure.

EOS treatment with MAGEC reduces the number of times the patient will be exposed to anesthesia, and limits their chances of acquiring infections. Since MAGEC allows the child to forego multiday stays in the hospital every six months, they are able to avoid the repetitive anxiety associated with these distraction procedures. In addition, the noninvasive distractions in an office setting result in a lower overall cost of treatment. As a result, the patient and family experience of receiving treatment for EOS is transformed.

The traditional surgical treatment for patients with moderate to severe cases of EOS requires an initial surgery, typically between the ages of five and seven. A growing rod is implanted as an internal brace to halt the deformity, and the patients undergo additional planned distraction surgeries every six months, allowing for continued growth during treatment. Sometimes these distraction surgeries can total to an additional 14 procedures beyond the initial surgery.

 

How it Works

 

Screen Shot 2017-01-11 at 8.01.21 AM.pngThe MAGEC rod is a titanium spinal rod that is surgically implanted and secured using spinal fixation components such as pedicle screws, hooks and/or connectors. The key to the MAGEC system is the magnetic interaction between the MAGEC implant and the hand-held MAGEC External Remote Controller (ERC) – used at various times throughout treatment to lengthen the implanted MAGEC rod from outside of the body.

In a standard office visit, the ERC is held over the child’s spine and activated. Magnets within the ERC cause a magnet in the rod to rotate, and the MAGEC rod is either lengthened or shortened as a result. The rod distractions allow the physician to drive or follow natural patient growth until he/she deems the MAGEC rod has achieved its intended use. At this point, the MAGEC rod(s) will be explanted, and the patient will undergo a final correction and fusion procedure.
