半肩人工关节置换治疗肱骨上段肿瘤

Unconstrained hemi-arthroplasty in treatment proximal humeral tumors

目的 探讨非限制性人工半肩关节置换在治疗肱骨上段肿瘤或肿瘤样病变中的应用效果。 方法 18例患者均为单侧病损,均使用定制的非限制性人工肱骨头假体置换,柄用骨水泥肱骨残端髓腔内 固定。患者平均年龄42岁,术后平均随访3.2年(0.5至5.8年)。结果 术后肩关节疼痛缓解率为 88.9%,主动活动度增加,按国际保肢学会(ISOLS)的评估标准进行评分,其中优6例,良8例,可2例,差2 例,优良率为77.8%。术后出现假体松动2例。结论 非限制性半肩人工关节置换治疗肱骨上段肿瘤有 良好效果,是肱骨上段肿瘤切除后保全肢体、提高患者生存质量的一种疗效可靠的手术方法。

Objective To evaluate the results of 18 unconstrained hemi-arthroplasties of shoulder in treatment of proximal humeral tumors. Methods 18 unconstrained hemi-arthroplasties of shoulder were performed on patients with giant cell tumors and osteosarcoma and chondrosarcomaand metastatic tumor and eosinophilia granuloma of bone. The patients’ average age was 42 years. Follow-up averaged 3.2 years. Results Pain was relieved in 88.9% patients and active range of motion increased after surgery. The rate of the excellent or good was 77.8% in according to the ISOLS score. Conclusion Unconstrained hemi-arthroplasty in treatment of proximal humeral tumors is a satisfactory and safe technique.
