OBJECTIVE: This article describes the design and fabrication of individualized pelvic prostheses by integrating three-dimensional (3D) printing technology with design software, and evaluates their feasibility and clinical efficacy.
METHODS: Based on the patient's anatomical structure and biomechanical requirements, individualized pelvic prostheses were designed using digital reconstruction software, manufactured by combining 3D printing and machining technologies, and finally verified for feasibility through clinical application.
RESULTS: Through adequate doctor-engineer interaction and detailed preoperative planning, precise individualized resection of the patient's tumor range was completed; guided by the pelvic tumor classification theory, individualized pelvic prostheses were designed and manufactured. Clinical application showed that the prostheses were consistent with the surgical plan and accurately implanted, with complete postoperative pelvic reconstruction and good healing.
CONCLUSION: This article summarizes the previous theoretical basis and sorts out the key design points of prostheses corresponding to different pelvic defect classifications; by using digital reconstruction software, combined with 3D printing technology and machining processes, the design and fabrication of individualized pelvic prostheses were completed; the feasibility and effect of the prosthesis design were verified through clinical application, providing a new approach for clinical medicine to repair defects after pelvic tumor osteotomy and other special lesions.
