Once we’ve identified your child’s condition, our care teams work together to create a personalized treatment plan that meets your family’s needs.

Treatment is led by our world-renowned pediatric orthopedic experts, including William Mackenzie, MD. Since skeletal dysplasia can evolve and change with time, Nemours has established one of the world’s top pediatric imaging programs to track and measure changes to children’s bodies.
