摘要
A growing rod for mounting between attachment mechanisms that are secured to anatomical structures of a patient having scoliosis. The growing rod includes an outer housing and an inner housing disposed within the outer housing. The inner housing includes a magnet assembly including a magnet having a first pole and a second pole and a gear reduction mechanism coupled to the magnet. A first rod is secured to the inner housing and a second rod is secured to the outer housing. The gear reduction mechanism reduces an output rotation of the magnet to rotate a driver that operates to move the inner housing along a longitudinal axis with respect to the outer housing.
