背景：我们开发了一种冷冻自体移植技术，用液氮处理肿瘤骨进行重建。本研究的目的是评价肱骨肿瘤切除后该技术的功能结局。患者和方法：本研究纳入8例患者。根据肱骨头关节面是否冻结，将冻结范围分为2组。结果如下：在关节冷冻组中，平均主动肩关节外展和屈曲分别为43.8和55.0，平均国际保肢协会（ISALS）评分为70.8%。在关节保留组中，平均主动肩关节外展和屈曲分别为130和132，平均ISOLS评分为90.8%。3例出现进行性大量骨吸收。讨论内容：在肱骨肿瘤切除后使用冷冻自体骨移植重建是我们的首选，特别是在保留肩关节的手术中。
Background: We developed a frozen autograft technique in which a tumor-bearing bone was treated with liquid nitrogen for reconstruction. The purpose of this study was to evaluate the functional outcomes of this technique after resection of humeral bone tumors. Patients and Methods: Eight patients were included in the study. The freezing range was classified into 2 groups, depending on whether the joint surface of the humeral head was frozen. Results: In the joint freezing group, the mean active shoulder abduction and flexion were 43.8 and 55.0, and the mean International Society of Limb Salvage (ISOLS) score was 70.8%. In the joint preservation group, the mean active shoulder abduction and flexion were 130 and 132, and the mean ISOLS score was 90.8%. Progressive and massive bone absorption was seen in 3 cases. Discussion: Reconstruction using frozen autograft after resection of humeral bone tumor is our preferred option, especially in shoulder joint preservation surgery.
