Orthopedic implants designed as a solid magnetically expandable rod that are surgically inserted to reshape spinal vertebrae that have lateral angular deformation from the normal vertical line (i.e., scoliosis). These implants are straight metal (e.g., stainless steel, titanium) rods that are surgically inserted and fixed along the spine to hold the vertebrae and avoid further deviation; the rods permit elongation along the axis using external magnetic control (i.e., perform periodic distraction of the vertebrae) without the need of additional surgical procedures after implantation. One or two magnetic-controlled distraction rods are usually implanted in patients, mainly children, diagnosed with scoliosis.
