Expansible Spinal Implant for Treatment of Early Onset Scoliosis (EOS)
Scoliosis is a medical condition in which a person's spine has a sideways curve. The curve is usually "S"- or "C"-shaped. Spine deformity begins before the age of 10 year. In some of the patients, degree of curve is stable while in others it might increase with the time. Scoliosis is variation depends on the angle of curvature which is measured angle of curvature is called Cobb’s angle. The goal of the study is children with EOS is to control the curve deformity, allow spiral movement, chest wall growth, lung development and improve pulmonary function, therefore provide better quality of life. Traditional Growing rods (TGRs) are commonly used in treatment of early onset scoliosis (EOS). They require periodic surgeries for lengthening and allow continued spinal growth1. Recent studies on TGR have shown that frequent surgical lengthening significantly increases the risk of complications2.We are developing a newly designed remote-controlled Expansible spinal instrumentation system proposed for the treatment of progressive scoliosis in young children. It can be used to stretch and correct the spinal deformities repeatedly and non-surgically, by means of a remote controller, after the first instrumentation operation.
