肿瘤型假体翻修手术的相关策略

[目的]分析肿瘤型假体置换术后翻修手术的原因，探讨手术的策略。[方法]10a间完成5例患者的肿瘤性假体翻修手术。男4例，女1例；平均年龄41．2岁。股骨远端4例，胫骨近端1例。再手术时间3．29a。翻修手术的原因均为假体松动，其中2例患者伴有窦道，1例假体远端断裂。翻修手术时2例应用原假体，3例应用新制作的假体，改为旋转铰链膝关节。[结果]本组5例均获得随访，最长为5a，最短为1a，平均为2a 4个月。5例均无瘤生存，假体无松动，切口愈合良好，关节功能的评分为21．5分。[结论]对于出现假体松动的患者，应及时行翻修手术，可获得较理想的肢体功能。

Revision after limb salvage surgery with prostheses for bone tumors

[ Objective ] To analyze the causes of revision for bone tumor salvage limb operations and to explore the therapies. [ Method ] There were 4 cases of male, 1 of female and with the mean age of 41.2 years old. The time between the first operation and revision was from 3 to 29 years. The common reason for revision was aseptic loosening, 2 patients with sinus and 1 with fracture of prosthesis. During revision, the old prosthesis were implanted in 2 cases, the new one were used in the others. [ Result] Ail patients were followed up with the mean time of 28 months, no patient died. The mean score of limb function was 21.5. [ Conclusion] Revision should be performed as soon as the prosthesis aseptic loosening has been determined, and the satisfactory limb function could be obtained.
