目的：推荐一种不切断骨在体内酒精灭活治疗原发性恶性骨肿瘤的方法，以缩短治疗周期，延长使用周期和减少骨愈合方面的并发症。方法：利用原发恶性骨肿瘤膝关节上、下高发的特点，解离关节，清除瘤灶，将含瘤骨段套入塑料袋中，并注入９５％ 酒精。灭活后修复缺损的骨，重建关节。共治疗８ 例。结果：获得随访的８ 例，中位时间２３ 个月（８～４２ 个月）。１ 例因软组织复发而截肢，２ 例因肺转移死亡，但无１ 例灭活骨复发，５ 例肢体功能满意。结论：体内酒精灭活治疗原发恶性骨肿瘤是一种较理想的灭活控制局部复发的方法。由于无需骨折愈合，肢体功能恢复满意
OBJECTIVE: To recommend a method of non-severed bone in vivo for the treatment of primary malignant bone tumors with alcohol in order to shorten the treatment cycle, prolong the use cycle and reduce the complications of bone healing. Methods: Using the characteristics of primary and secondary malignant bone tumors in the upper and lower knee joints, the joints were dissociated and the tumor was removed. The tumor-bearing bone segments were placed in plastic bags and infused with 95% alcohol. Repair the damaged bone after inactivation and reconstruct the joint. A total of 8 cases. RESULTS: Eight patients were followed up for a median of 23 months (range, 8 to 42 months). One case was amputated due to recurrence of soft tissue, and two died due to lung metastasis. However, none of the cases had inactivated bone recurrence and 5 cases had satisfactory limb function. Conclusion: In vivo alcohol inactivation treatment of primary malignant bone tumors is a more ideal method of inactivation to control local recurrence. As no fracture healing, limb functional recovery satisfaction
