骨肉瘤为原发恶性骨肿瘤中发病率最高的疾病,致死率及致残率很高,文献报道新辅助化疗后的5年生存率为50%~60%[1-3],特别是对于儿童,由于其存在骨骼生长问题,而肿瘤往往侵犯骨骺和干骺端,保肢手术很难避免远期的肢体不等长的问题。牵拉成骨术最早被广泛应用于肢体不等长、骨不愈合、创伤性骨缺损、畸形和骨髓炎的治疗,其在骨肿瘤切除手术的应用并不常见。 Osteosarcoma is a disease with the highest incidence in primary malignant bone tumors. The mortality and disability are very high. The 5-year survival rate after neoadjuvant chemotherapy is reported in the literature range from 50% to 60% [1-3], especially for Children, due to their presence of bone growth problems, and tumors that often invade the epiphyseal and metaphysis, limb salvage surgery is difficult to avoid the problem of unequal length of the limbs. Traction osteosynthesis was first widely used in the treatment of unequal limbs, nonunion, traumatic bone defects, deformities and osteomyelitis, and its application in resection of bone tumors is not common.
