The signing ceremony of the "GPS Universal Pelvic Ring Reconstruction System" technology transformation project of the team of Professor Guo Wei from the Department of Orthopedic Oncology, Peking University People's Hospital was held in Beijing. According to reports, the "3D printed pelvic prosthesis" technology successfully developed by the Chinese scientific research team will not only benefit more patients, but will also break the monopoly of imported products and reduce medical expenditures for the masses.
Clinically, sacrum and pelvic tumors are often very large because they are not easy to find. For a long time, the pelvis has been regarded as a forbidden area for bone tumor surgery. Especially the anterior and posterior combined resection of sacral tumors was once called "unresectable surgery" in the industry. Many patients develop paraplegia due to the rapid progress of local tumors. The severe pain makes the patients feel uncomfortable. For this reason, once discovered, the only treatment is amputation.
In recent years, with the development of 3D printing technology and its continuous expansion in the medical field, the application of this innovative technology in the field of orthopedics has emerged.
In 2015, Guo Wei's team developed a full range of 3D printed pelvic ring artificial prostheses (GPS universal pelvic ring reconstruction system) such as sacral restorations, iliac restorations and acetabular defect reconstruction prostheses. The research results have successively obtained national technological advancements The second prize, the first prize of China Medical Science and Technology Progress Award, and the second prize of Beijing Science and Technology Progress Award.
According to reports, the "3D printed modular artificial half pelvic prosthesis" (Globle Pelvic System, referred to as GPS) was designed and completed in 2015 to further improve the "artificial half pelvic prosthesis" designed in 2002 for reconstruction of pelvic tumor limb salvage surgery. “Prosthesis” to further optimize the mechanical design of the semipelvic prosthesis and increase the bone ingrowth function of the prosthesis. Research has found that the prosthesis can perfectly fuse with the patient’s autologous bone. So far, more than 300 cases have been used in clinical practice, and good clinical results have been achieved, and complications have been greatly reduced.
GPS consists of four parts, which respectively take on different functions, replacing the removed pelvis, sacrum, hip joints, etc., to help patients stand up again and walk normally.
