目的 :探讨恶性骨肿瘤保肢术中应注意的几个问题。方法 :自 1991年 6月 ,对 64例恶性骨肿瘤行保肢手术 ,男 41例 ,女 2 3例 ,年龄平均 2 9.9岁 ,Ⅰ A2例 ,ⅠB5例 ,ⅡA12例 ,ⅡB40例 ,ⅢB5例。 5 8例获得平均 2 1.9个月的随访。结果 :5例发生肺转移 ,5例死亡 ,6例复发。保肢手术成功率为 79.3 % ,肢体功能优良率为 76.7%。结论 :人工关节置换术为最佳选择 ,术前严禁手术部位的外照射 ,禁止瘤腔内手术。对于复发的恶性骨肿瘤根据不同的情况 ,采取不同的术式。
Objective: To discuss several issues that should be paid attention to in limb salvage surgery for malignant bone tumors. METHODS: From June 1991, 64 patients with malignant bone tumors underwent limb salvage surgery. There were 41 males and 23 females, with an average age of 29.9 years. There were 2 cases of I A, 5 cases of IB, 12 cases of IIA, 40 cases of IIB, and 5 cases of IIIB. Fifty-eight patients received an average of 2 1.9 months of follow-up. Results: 5 cases of lung metastasis occurred, 5 cases died, and 6 cases recurred. The success rate of limb salvage surgery was 79.3%, and the excellent and good limb function was 76.7%. Conclusion: Artificial joint replacement is the best choice. External irradiation of the surgical site is forbidden before surgery and intratumoral surgery is forbidden. For the recurrence of malignant bone tumors, different procedures are adopted depending on the situation.
