髋关节假体置换术后并发症及其处理

从1984年以来共处理人工髋关节末后并发症12例。其中感染2例,脱位2例,假体松动与骨折各2例、髋部异位骨化4例。我们认为严重感染病例应及时取出假体,引流伤口,感染控制后第2期置入假体。较轻病例则应积极抗感染,力争保留假体。假体松动常与手术操作技术有一定关系,一旦确诊,须尽平行翻修术。异位骨化症Ⅲ、Ⅳ期病例应手术治疗,术后口服消炎痛或行局部放疗。

COMPLICATION FOLLOWING HIP PROSTHESES AND ITS TREATMENT

Since 1984. we have treated 12 cases of complication following hip prostheses. Of all the cases , there were 2 cases of infection. 2 cases of dislocation, 4 cases of fracture or prostheses loosening and 4 cases of heterotopic ossification. For the cases of serious infection, we should immediately take out the prostheses and drain the wound. After controlled the infection, prostheses can be implanted again. For the cases of mild infection, we should try our best tomaintain the prostheses. And at the same time a large dosage of antibiotic should be given. The reason of prostheses loosenin is usually related to the technique of operation. When the diagnosis of pros-theses loosening is clear, we should perform reopera-tion at early. The ectopic-bone should be resected by operation for the cases of the stage I or IV of heterotopic ossification. After operation, indomethacine or local radioactive treatment should be given.
