When you think of 3D printing, what comes to mind? Is it a children’s toy or an architectural model? Today, 3D printing brings tangible benefits to surgical patients. Recently, the Department of Joint Surgery and Sports Medicine of Qingdao People’s Hospital of Peking University has deeply integrated 3D printing with orthopedic surgery to perform 3D printing joint replacements and other procedures. surgical procedures in order to create tailor-made prostheses and successfully resolve the problems of many difficult patients. .
A month ago, Mr. Zhao (pseudonym) and his wife, who were working in Qingdao, were unfortunately involved in a car accident on their way to work and were rushed to the People’s Hospital from Peking University, Qingdao Hospital. The emergency doctor urgently assessed the injuries and found that Mr. Zhao had a dislocation of the right hip joint, a fracture of the right femoral head, an open fracture of the nasal bone, a fracture of the skull. , cerebral contusion and laceration, subarachnoid hemorrhage, blunt trauma to the right eyeball. , rib fracture, etc. For complex and critical situations, the hospital immediately activates the emergency response system and organizes multidisciplinary joint care.
After a multidisciplinary consultation, the patient was rushed to the operating room. The Department of Joint Surgery and Sports Medicine associated with the Department of Ophthalmology and the Department of Otolaryngology and Head and Neck Surgery performed reduction of the right hip joint, debridement and suturing of both eyelid fissures. and nasal trauma. Once the patient’s condition was stabilized, Professor Fu Zhongguo, an orthopedic expert at Peking University People’s Hospital, estimated that traditional surgical screw fixation would require at least 3 to 6 months of bed rest in order to allow the patient to recover as quickly as possible and remain in bed. To reduce the risk of femoral head necrosis and complications, he suggested using 3D printing to personalize the patient’s condition. A custom prosthesis was used to perform the right femoral head surface replacement on the patient.
The medical team collected CT data, printed the right femoral head based on an individual mirror image of the defect, customized surgical tools and carried out the operation. Three days after the operation, Mr. Zhao could walk normally. After careful treatment by medical staff, the patient’s condition remained stable and he was successfully discharged from the hospital.
The application of 3D printing technology in the medical field is one of the hot spots. It is also called additive manufacturing. It refers to the manufacturing of three-dimensional solid components from materials based on digital models, point by point, line by line. and layer by layer in the three-dimensional direction. Sex manufacturing technology can be widely used in areas such as preoperative planning and prerehearsal, surgical guides and rehabilitation supports, orthopedic matching and human implants.
Traditional prosthetics are often standardized and may not fit the patient’s anatomy perfectly, leading to postoperative discomfort or limited function. 3D printing technology allows the creation of highly personalized prostheses based on the patient’s specific bone morphology, so that the prosthesis can closely fit the host bone. This personalized design improves the success rate of surgery and reduces the occurrence of postoperative complications.
The combination of surgery and 3D printing technology is not new to Peking University People’s Hospital, Qingdao Hospital. Peking University People’s Hospital is one of the first medical institutions in the country to apply 3D printing technology. As early as January 2020, Fu China has applied 3D technology to clinical practice and accumulated rich experience. As a national regional medical center construction unit, Qingdao Hospital gives full play to the advanced technological advantages of Peking University People’s Hospital and keeps pace with scientific and technological development. The Department of Joint Surgery and Sports Medicine regularly applies 3D printing technology. all types of surgeries currently performed in the department (shoulder, elbow, hip, knee and ankle) to offer more patients more precise and personalized medical services. The department will continue to explore more applications of 3D printing technology in the field of orthopedics. , continue to promote precise and minimally invasive treatment of complex fractures, and further improve the quality and efficiency of medical services.
