The purpose of my Churchill Fellowship was to determine the potential for additive manufacturing (i.e., 3D printing) to be integrated into the management pathway for children with bony deformities. The great advantage of additive manufacturing is that is capable of fabricating complex shapes, and manipulating material properties that are impossible with traditional manufacturing methods and for these reasons show immense potential. The major conclusions from my fellowship are as follows:

  1. Equal time and effort should be invested in the quality processes that inform pre-operative planning of surgery for complex lower limb deformities. More research on advanced patient specific computational simulations is required to enable a more objective surgical prescription process, and better understanding of actual loads experienced by bones and implants during human movement.
  2. The relationship between the orthopaedic surgeon and the design, or clinical, engineer is crucial during the design phase of any custom 3D printed patient specific product. The surgeon should be actively involved in the design phase of the product and be provided an opportunity to gather hands on experience with any new surgical guide concepts.
  3. Effective collaborative pre-planning and additive manufacturing will allow the surgeon to execute the surgical plan in theatre in an accurate, precise and efficient manner. Nonetheless, it recommended that more research be conducted on the efficacy of patient specific surgical guides, as there remains a paucity of research in this area.
  4. Industry and research institutions need to collaborate with regulatory authorities in the near future to ensure product quality and safety, whilst not overburdening the quality control process with redundant methodologies.
