Zoé and her rare congenital scoliosis
3D-printed anatomical model
Not only did the condition affect her physical health, but it also took a significant toll on Zoé's mental well-being. She often felt self-conscious about her appearance and struggled to fit in with her peers. Participating in sports or even simple activities like sitting for long periods became increasingly difficult
After eight unsuccessful surgeries, Zoé needed a new intervention to restore her lung capacity, which had been significantly reduced due to the spinal curvature. The curvature was so severe that her lungs could no longer function properly and she required constant oxygen supplementation
Design and simulate a 3D model of Zoé's spine
As Zoé's condition worsened, the Rotary Club of Florida Satellite and Dr. Vilchis sought a cutting-edge technology that could minimize surgical risks. They turned to Materialise Mimics Innovation Suite to create an accurate 3D model of Zoé's deformed spine in the shortest possible time. Zoé underwent a CT scan, and the 2D medical images were transformed into a vivid 3D model using Mimics
The STL mesh of the vertebra is ready for finite element analysis (FEA)
Through intricate image processing, the 3D simulation software reconstructed every minute detail of Zoé's spine, from the curved vertebrae to the surrounding nerves. Unnecessary details were removed, highlighting critical areas and adjusting the scale to match real-world dimensions
Zoé’s spine reconstruction using Mimics Medical for preoperative planning
Subsequently, the medical team 3D printed a replica of Zoé's spine using Stratasys PolyJet technology, a process that solidifies plastic using UV light to create extremely detailed and accurate parts. This model enabled surgeons to examine Zoé's spine from every angle, precisely measure various parameters, and meticulously plan the surgery

A groundbreaking surgery using 3D printing technology
Dr. Vilchis emphasized the crucial role of the 3D model in the surgery. Thanks to this model, the surgeries were exceptionally successful, particularly the second one. The first surgery, involving the placement of screws and rods, was completed quickly and flawlessly, reducing the operating time by 40%
Zoé's second surgery posed a significant challenge for the medical team. Removing the vertebrae to correct the curvature required utmost precision, as any error could have had severe consequences. However, a critical situation arose during the procedure when the spinal cord ceased functioning, risking the patient's mobility. Relying on the 3D model, the doctors made a swift and accurate decision, successfully saving the young girl's life
Zoé's family and Dr. Vilchis' medical team
The success of this surgery not only brought hope to Zoé but also opened up new possibilities in the treatment of spinal disorders. With the support of the Rotary Club of Florida Satellite, 3D technology will be increasingly accessible, providing hope for countless other patients

The application of 3D printing technology in medicine
The application of 3D printing technology in medicine, particularly in surgery, is revolutionizing patient care. Zoé's surgery is a prime example of the immense potential of this technology. However, to fully realize the benefits of 3D printing, continued research, development, and addressing existing challenges are essential
Advantages:
- High Level of Personalization: Each patient has a unique anatomical structure. 3D printing technology allows for the creation of highly accurate 3D anatomical models, enabling surgeons to optimally plan and personalize surgical procedures for individual patients.
- Increased Precision: 3D models provide a detailed map of the surgical site, allowing surgeons to perform procedures with greater accuracy and minimize risks.
- Reduced Surgical Planning Time: Advanced 3D modeling software, such as Materialise Mimics, enables rapid and detailed preparation of 3D anatomical models, accelerating the diagnostic and surgical planning processes.
- Shorter Surgery Time: Thorough preparation based on 3D models can significantly reduce surgery time.
- Reduced Recovery Time: More precise and less invasive surgeries often lead to faster patient recovery.
- New Possibilities in Surgery: 3D printing technology enables the creation of customized surgical instruments, artificial implants, and even artificial tissues and organs in the future
Patient-specific 3D-printed anatomical model
Disadvantages:
- High Cost: Currently, the cost of 3D design software, medical 3D printers, and printing materials is still quite high, making it difficult for many medical facilities to access this technology.
- Limited Materials: Biological 3D printing materials need to meet stringent requirements in terms of biocompatibility, non-allergenicity, non-infection, and durability. Finding and producing such materials is still limited.
- Legal Regulations: The application of 3D printing technology in medicine requires strict compliance with legal regulations regarding product quality, safety, and efficacy, creating certain barriers to the development and application of the technology.
Practical Applications:
Creating detailed 3D anatomical models:
- Purpose: Doctors and medical students can create 3D models of patients to better visualize the anatomical structure of the human body (especially in complex cases, tumors), thereby enabling detailed and accurate surgical planning
- Applications: Orthopedic surgery (joint replacement, fracture repair, and spinal disorders), Cardiovascular surgery (heart, blood vessels), Neurosurgery, Oral and maxillofacial surgery (orthodontics, dental prosthetics),...
Fabrication of custom surgical instruments
- Purpose: To create surgical instruments for complex and challenging surgeries, or for patients with unique anatomical structures, tailored to specific cases, thereby increasing the precision and efficacy of surgery
- Applications: Instruments for tissue fixation, guiding tubes, or creating spaces during surgery
