软骨肉瘤是常见的恶性骨肿瘤,发生率仅次于成骨肉瘤,占原发性骨肿瘤的17～22％。盆骨是软骨肉瘤的好发部位,约占总数的25～31％,以往常用半骨盆截肢术治疗(Hemipelvectomy),但后遗残废很大。近年来有些学者采用保留下肢的局部根治性切除,既根治了疾病又获得良好的功能保持,我院曾作1例,报导如下。 Chondrosarcoma is a common malignant bone tumor. The incidence is second only to osteosarcoma, accounting for 17-22% of primary bone tumors. The pelvic bone is a predilection site for chondrosarcomas, which accounts for 25 to 31% of the total. In the past, hemipelvicectomy was commonly used (Hemipelvectomy). In recent years, some scholars have used local radical resection to preserve the lower extremities. They have both cured the disease and maintained good function. Our hospital once made 1 case and reported as follows.
