Spinal Tethering Surgery is an innovative surgical approach primarily used to treat idiopathic scoliosis in growing patients. Tethering aims to correct the spinal curve while preserving motion and flexibility in the treated segments. The procedure involves placing screws into the vertebrae along the outer (convex) side of the spinal curve, which are then connected by a strong, flexible cord or "tether." By applying tension to this tether, it gently guides the spinal growth on the convex side, effectively slowing its growth while allowing the concave side to continue growing normally, thus gradually straightening the curve over time as the patient grows. This makes it an appealing option for select young individuals who meet specific criteria regarding their curve severity and remaining growth potential.
