烟台毓璜顶医院依托3D打印技术以毫米级精度为患者再造新胸骨

Core Viewpoint - 3D printing technology is emerging as a key solution to address complex medical challenges, particularly in the field of orthopedic surgery for tumor reconstruction [1][3]. Group 1: Application of 3D Printing in Medicine - Yantai Yuhuangding Hospital's trauma orthopedic department has pioneered the use of 3D printed custom prosthetics for post-operative fixation failure in chest bone tumors, showcasing the hospital's advanced capabilities [3][11]. - The use of 3D printing allows for personalized chest bone prosthetics that overcome traditional surgical limitations, providing precise reconstruction with millimeter-level accuracy [3][11]. Group 2: Case Study of Patient Treatment - A 47-year-old female patient suffering from chest pain due to a malignant tumor in the chest bone underwent a series of treatments, including tumor resection and chest reconstruction, but faced complications due to the failure of the implanted steel plate [4][6]. - After consulting with Dr. Sun Yujie, the team identified the cause of the pain and decided to utilize 3D printing technology to create a custom prosthetic that would address the significant bone defect [6][9]. Group 3: Surgical Process and Challenges - The surgical team faced multiple challenges, including safely removing the failed implant and accurately inserting the new 3D printed prosthetic without damaging surrounding organs [9][11]. - The surgery lasted nearly five hours, during which the team ensured the stability and safety of the new prosthetic by using pre-drilled holes for secure attachment to the surrounding bones [11]. Group 4: Benefits of Custom Prosthetics - The use of 3D printed prosthetics not only meets the individual needs of patients but also enhances biomechanical compatibility, significantly improving surgical safety and post-operative recovery [11]. - This innovative approach opens new pathways for complex bone tumor repairs, providing hope for many patients suffering from similar conditions [11].
