The Role of 3-D Technology in World’s First Successful Double Hand and Face Transplant

Three-dimensional technologies, developed by Materialise, played a crucial role in the world’s first simultaneous double hand and face transplant that was successfully performed at NYU Langone Health in Manhattan. Materialise’s innovative 3-D planning and printing tools enable the speed and accuracy required for such a complex medical procedure. Three-dimensional printed personalized tools such as those used in the double hand and face transplant are also increasingly common for use in routine surgery, providing surgeons with an additional level of confidence which results in improved patient outcome.

The 22-year old patient suffered burn wounds resulting from a car accident, leaving him with severe injuries to his face and both arms. He suffered significant damage to his soft tissue, which severely limited his ability to lead a normal life. During a preparation period of 14 months, Materialise clinical engineers formed a cohesive team alongside NYU Langone surgeons, rehearsing the operation in a lab environment to develop and fine-tune the surgical plan. Once a suitable donor was found, the team, led by Eduardo D. Rodriguez, M.D., the Helen L. Kimmel Professor of Reconstructive Plastic Surgery and chair of the Hansjörg Wyss Department of Plastic Surgery at NYU Langone, had only 24 hours to begin the procedure that would improve the patient’s function, appearance and quality of life.

CT Scans Aid Surgical Plan With On-screen 3-D modeling 

In the months leading up to the surgery Materialise engineers coordinated the development of a surgical plan and created an on-screen 3-D model based on computed tomography (CT) scans. This allowed the surgeons and clinical engineers to virtually plan the procedure and visualize different scenarios in three dimensions, creating an in-depth understanding of the anatomical bone structure and determining the optimal surgical flow. Pre-surgical planning also made it possible for surgeons to virtually select and position various medical implants to predict the optimal anatomical fit. Once the surgical plan was finalized, Materialise 3-D printed the personalized surgical guides, anatomical models and tools for use during the transplant surgery.

CT Scans Used to Create 3-D Printed Cutting and Drilling Guides

During this momentous procedure, Rodriguez and his surgical team of sixteen used Materialise’s 3-D printed cutting and drilling guides. This fully guided system for bone fragment repositioning and fixation was unique to the patient’s anatomy and helped position the medical tools with great precision, reducing the overall surgery time. Additionally, Materialise created 3-D printed sterilizable identification tags for nerves and blood vessels, 3-D printed models that were used during donor transport, and 3-D printed splints, enabling optimal donor hand position during soft tissue reconstruction.

“Complex transplant surgery like this brings together a large team of specialists and presents new and unique challenges”, said Rodriguez. “This demands careful planning and makes timing, efficiency and accuracy absolutely critical. Virtually planning the surgery in 3-D and creating 3-D printed, patient-specific tools offers additional insights in the pre-operative phase and increased levels of speed and accuracy during a time-critical surgery”.

Image-based Planning and 3-D Printing is Revolutionizing Personalized Medicine

“Image-based planning and medical 3-D printing have completely revolutionized personalized patient care by providing surgeons with detailed insights and an additional level of confidence before entering the operation room,” says Bryan Crutchfield, Vice President and General Manager – North America. “As a result, leading hospitals are adopting 3D planning and printing services as part of their medical practices because they create a level of predictability that would be impossible to achieve without the use of 3-D technologies.”

Materialise has pioneered many leading medical applications of 3-D printing and enables researchers, engineers, and clinicians to develop innovative, personalized treatments that help improve and save lives. The Materialise platform of software and services forms the foundation of certified medical 3D printing in clinical and research environments, offering virtual planning software tools, 3D-printed anatomical models, and personalized surgical guides and implants.
