[Pelvic limb-salvage surgery for malignant tumors: 30 years of progress in China].

This article reviews the development and progress in the field of limb salvage treatment, surgical techniques, and function reconstruction of pelvic malignant tumors in China in the past 30 years. Based on the surgical classification of pelvic tumor resection in different parts, the development of surgical techniques and bone defect repair and reconstruction methods were described in detail. In recent years, in view of the worldwide problem of biological reconstruction after pelvic tumor resection, Chinese researchers have systematically proposed the repair and reconstruction methods and prosthesis design for bone defects after resection of different parts for the first time in the world. In addition, a systematic surgical classification (Beijing classification) was first proposed for the difficult situation of pelvic tumors involving the sacrum, as well as the corresponding surgical plan and repair and reconstruction methods. Through unremitting efforts, the limb salvage rate of pelvic malignant tumors in China has reached more than 80%, which has preserved limbs and restored walking function for the majority of patients, greatly reduced surgical complications, and achieved internationally remarkable results.
