Enabling precision medicine: application of 3D printing technology in bone and joint surgery

2024-04-02 15:21:10  News

3D printing technology has become one of the important tools in modern manufacturing and medical fields. It is gradually penetrating various branches of the medical field, especially in the field of bone and joint surgery, where 3D printing technology has shown great potential. and broad application prospects.

3D printing technology 

Overview of 3D printing technology

3D printing technology, also known as additive manufacturing technology, is a rapid prototyping technology based on digital model files. It can directly convert three-dimensional computer models into physical models using specific materials, such as plastic materials or metal powders, layer by layer. Printing is used to construct three-dimensional objects. This technology can manufacture products with complex structures without using traditional cutting, engraving, and other methods of removing material. Compared with traditional subtractive manufacturing processes, 3D printing technology has significant advantages such as flexible design, fast speed, low cost, and the ability to manufacture complex-shaped products.

Application of 3D printing technology in bone and joint surgery

Preoperative planning: In bone and joint surgery, accurate preoperative planning is crucial. Through 3D printing technology, doctors can create accurate bone models based on patients' CT scan data. These models not only help surgeons better understand the anatomy of the lesion but can also be used to simulate the surgical process, thereby rising the success rate of the surgery and shortening the surgery time. Such a model can not only help doctors better plan surgical strategies but can also be used for communication between doctors and patients, helping patients understand their disease conditions and surgical procedures more intuitively.

Customization of surgical guides: In repair surgery for complex fractures or bone defects, it is crucial to ensure precise docking of the implant with the bone. 3D printing technology can be used to design and produce surgical guides that can guide surgeons in precise cutting and drilling, thereby improving surgical accuracy, shortening operation time, and reducing the risk of complications.

Customized prostheses and implants: Traditional joint replacement surgery uses standardized prostheses. These prostheses often cannot perfectly fit the bone structure of each patient, and in some cases, patients have complex bone defects or diseases. Traditional standardized implants often fail to meet treatment needs. Using 3D printing technology, doctors can customize personalized implants based on the patient's specific anatomical characteristics. This personalized implant can better match the patient's bones, provide better biomechanical matching and higher safety, and improve the effectiveness of the surgery and patient comfort.

Bioprinting and tissue engineering: For complex fractures or bone defects, traditional treatment methods may not provide optimal results. 3D printing technology can print corresponding bone or scaffold structures according to the patient's specific conditions, making fracture repair or bone defect filling more accurate and effective. A further application is through 3D bioprinting technology, which can print biomaterials containing living cells to repair or regenerate damaged bone tissue. This technology is still in its infancy, but it is expected to achieve complete tissue engineering in the future and fundamentally solve the problems of tissue damage and organ loss.

Education and training: 3D printed bone models can not only be used for surgical planning and simulation but also as a tool for medical education and surgeon training. These models can help students and interns understand complex skeletal anatomy, and then practice operations on the models to accumulate experience. They provide a more realistic and interactive learning experience than traditional teaching, which is helpful for the training of future doctors and the improvement of surgical skills. Improve.

Advantages of 3D printing technology

Improved surgical accuracy: Because 3D printing technology can create models and implants based on individual patient data, this greatly improves the accuracy of surgical planning and reduces surgical risks.

Shorten surgery time: Pre-made models and implants can reduce trial and error during surgery. Doctors can be familiar with the patient's anatomy in advance, reducing intraoperative uncertainty and thereby shortening the overall surgery time.

Increase patient comfort: Customized implants can better integrate into the patient's body, reduce foreign body sensations, and improve the patient's comfort during postoperative recovery.

Reduce surgical trauma: Using 3D printing technology, surgeons can more accurately position the surgical area, thereby minimizing damage to surrounding tissues and reducing surgical trauma.

Challenges facing 3D printing technology

Although 3D printing technology shows great promise in bone and joint surgery, it still faces some challenges and limitations:

Material issues: There currently needs to be more biocompatible materials available for 3D printing, and the biomechanical properties of these materials cannot fully meet clinical needs.

Cost issue: The cost of 3D printing equipment and materials is high, which may affect its popularity in clinical practice.

Regulations and standards: Currently, regulations and standards for 3D printed medical products still need to be completed, which brings certain difficulties to clinical application and market promotion.

Technical threshold: Doctors and engineers need to be familiar with 3D printing technology and related software, which requires specialized training and learning, making technology applications more difficult.

3D printing technology provides new directions and tools for bone and joint surgery, from the manufacturing of personalized implants to the customization of surgical guides, from the printing of bone models to bioprinting and tissue engineering, and its application scope is constantly expanding. Through precise, personalized medical solutions, 3D printing technology can not only improve surgical outcomes but also enhance patients' quality of life. With the advancement of technology, reduction of costs, and improvement of relevant regulations and standards, it is expected that this technology will play an increasingly important role in the medical field, especially in bone and joint surgery, which heralds the future development of the medical field.
