The minimally invasive limb lengthening surgery involves clearing a path for the Nuvasive Precice titanium nail, surgically breaking the bone, and then implanting the nail. After the procedure, the Precice lengthening nail is actuated by an external magnetic controller which will gradually separate the bone segments in a controlled fashion. As the bone segments separate, new cells form in the gap as the body tries to heal and eventually solidifies into solid bone.
