异体骨段复合人工股骨头置换治疗股骨近端骨转移癌

Allograft-prosthetic Composit Implanting for Proximal Parts of Femur Bone Metastasis

目的 :总结股骨近端骨转移癌患者行异体骨段复合人工股骨头置换的手术效果。方法 :13例患者术后平均随访 11.5个月。结果 :术后患者肢体功能改善 ,手术优良率为 84.6 % ;术后骨不连、假体松动、围手术期死亡各发生 1例。结论 :异体骨段复合人工股骨头置换术利于软组织修复重建和肢体功能康复 ,术前需综合评价患者的全身条件及局部转移灶状况。

Objective:To evaluate the surgical treatment methods of using allograft prosthetic implant composit for bone metastasis located in the proximal parts of femur and characterize the principles of operation. Methods:13 patients with bone metastasis in proximal parts of femur underwent allograft prosthetic composit implanting from 1993 to 1999. All patients were assessable and followed up(median 11.5 months). Results: 12 of the 13 patients increased mobility and relieved of pains after operation. It observed statistical significant acceleration of Karnofsky score and life activities. 1 patient died within 3 weeks after operation. Bone junction non union(1/13), prosthesis loosen(1/13) were the main postoperative complications. Death and distant metastasis were part of the disease process but not the operation related complications. Conclusion: It was observed statistical significant relieved patients pain and increased their mobility after recommended surgical treatment.
