This surgical procedure is performed through a posterior approach (back) of the patient. The main goal is to straighten the spinal cord in terms of balance with the pelvis and torso. Through a posterior approach, a small incision is made to gain access to the spinal cord. The process of fusing the vertebrae together comes into place to gain connectivity along the curve of the spine. Bone grafting is then performed after removal of the deformed bone from the spinal cord. Instrumentation methods such as steel rods, hooks, and other devices attached to the spine that are then used to hold conjoined vertebrae together.
