目的 评价骨恶性肿瘤及骨转移癌瘤段切除功能重建的意义。方法 采用 4种方法修复 :①北京亚华公司提供的长柄人工股骨头置换 ;②自制的甲基丙烯酸甲酯假体置换 ;③自体腓骨骨移植 ;④瘤段切除后关节融合术。结果 ①近期疗效 :18例患者术后疼痛消失 14例 ,占 88% ,术后疼痛减轻 2例占 12 % ;下肢瘤段切除人工关节置换者均在 3周内活动 ,10 0 %下床行走 ,其中不使用拐杖者占 66% ,使用单拐者占 33% ;②中远期疗效 :术后随访 5个月～ 13年 ,平均 4 8年 ,现存活共计 11例 ,占 74%。结论 应用上述方法瘤段切除后修复重建 ,能恢复肢体绝大部分或部分功能 ,消除和减轻疼痛 ,延长患者寿命 ,降低残废率 ,提高生存质量。
Objective To evaluate the significance of reconstruction of resection of malignant and metastatic tumors of bone. Methods Four methods were used to repair: ① long-handled artificial femoral head replacement provided by Beijing Yahua Company; ② self-made replacement of methyl methacrylate prosthesis; ③ autologous fibular bone graft; ④ arthrodesis after tumor resection. Results ① Short-term curative effect: In the 18 cases, postoperative pain disappeared in 14 cases (88%) and postoperative pain relief in 2 cases (12%). Lower extremity resection and artificial joint replacement were performed within 3 weeks and 10% , Of which 66% did not use crutches and 33% used single abdomen; (2) Mid-long term efficacy: The patients were followed up for 5 months to 13 years with an average of 48 years. There were 11 surviving patients (74%). Conclusions Applying the above method to repair and reconstruct tumor segments after resection can restore most or part of the functions of limbs, eliminate and relieve pains, prolong patients’ life, reduce the disability rate and improve the quality of life.
