目的探讨肱骨近端骨肿瘤施行人工肿瘤假体置换的手术适应证、近期疗效。方法 8例可连续随访和评估的肱骨近端骨肿瘤,其中骨巨细胞瘤3例,骨肉瘤4例,恶性纤维组织细胞瘤1例。均采用三角肌胸大肌间隙入路,切除病变组织,重建肩外展及内收功能,并进行早期术后功能锻炼。按Neer评分系统对术后的运动和功能方面进行评估并记录。结果术后平均随访23个月。随访期间无感染、关节松动、关节脱位、假体周围骨折并发症。Neer评分平均为84.3分,>90分2例,80～89分5例,70～79分1例,满意率达87.5%。结论人工肿瘤假体置换治疗肱骨近端骨肿瘤疗效较好,能达到切除肿瘤和保肢目的。由于随访时间短,长期疗效有待观察。
Objective To investigate the surgical indications of artificial tumor prosthesis replacement in the proximal humeral bone tumors and its short-term curative effect. Methods Eight cases of proximal humeral bone tumors were followed up and evaluated, including 3 cases of giant cell tumor of bone, 4 cases of osteosarcoma and 1 case of malignant fibrous histiocytoma. All deltoid muscle pectoralis major approach, removal of diseased tissue, reconstruction of shoulder abduction and adduction, and early postoperative functional exercise. The postoperative motor and functional aspects were evaluated and recorded according to the Neer scoring system. Results The average follow-up was 23 months. No infection during follow-up, joint looseness, joint dislocation, and complications of periprosthetic fracture. Neer score averaged 84.3 points,> 90 points in 2 cases, 80-89 in 5 cases, 70-79 in 1 case, the satisfaction rate was 87.5%. Conclusion artificial tumor replacement for the treatment of proximal humeral bone tumors better effect, to achieve the purpose of resection of the tumor and limb salvage. Due to the short follow-up, long-term efficacy remains to be seen.
