目的探讨特制人工关节假体置换技术在四肢恶性肿瘤保肢治疗中的作用及疗效。方法以特制关节假体行髋、膝、肩关节置换治疗关节邻近部位恶性骨肿瘤23例,术后以转移率、3年无瘤存活率、关节功能、肿瘤复发率、假体并发症等进行疗效评价。结果术后23例随访10-68个月,平均33个月。并发症发生率21.7%,3年无瘤存活率78.3%,按Enneking骨骼肌肉肿瘤术后肢体功能评定标准进行评估,23例患者优10例,良8例,可3例,差2例,优良率为78.3%。结论运用人工关节技术对合适的恶性骨肿瘤患者进行保肢治疗,可获得较为满意的疗效。
Objective To explore the effect and curative effect of special prosthesis replacement in salvage limb salvage. Methods Twenty-three cases of malignant bone neoplasms adjacent to the joint were treated with a special joint prosthesis in the hip, knee and shoulder joints. The postoperative metastatic rate, 3-year tumor-free survival rate, joint function, tumor recurrence rate and prosthesis complication Efficacy evaluation. Results 23 cases were followed up for 10-68 months, an average of 33 months. The complication rate was 21.7% and the 3-year tumor-free survival rate was 78.3%. According to the evaluation criteria of limb function after Enneking skeletal muscle tumor surgery, 23 patients were excellent in 10, good in 8, fair in 3, poor in 2 The rate is 78.3%. Conclusions Artificial joint technique for salvage limb salvage in patients with malignant bone tumors can achieve satisfactory results.
