Clinical Assessment of a Motorized Spinal Distraction Rod in the Severe to Early Scoliosis Child

Brief Summary

The purpose of this biomedical research is to evaluate the feasibility of the treatment with the new spinal distraction device ASTS in patients aged 4 to 10 years with severe early onset scoliosis. The hypothesis of this project is that the new fully implantable motorized spinal distraction device may provide a correction of scoliosis and progressive elongation ensuring patient comfort and minimizing complications. The ASTS (for Active Scoliosis Treatment System) growing rod is a new fully implantable motorized spinal distraction device which can ensure a correction of scoliosis and progressive elongation ensuring patient comfort and minimizing complications.
