Total elbow arthroplasty (TEA) was used as a salvage procedure following failed open reduction and internation fixation, failed triaxial arthroplasties, and septic and aseptic loosening of implant arthroplasty. A minimally constrained bicondylar implant with a block to disarticulation was substituted for the reconstruction of 20 revision TEAs. Custom-designed implant TEA was substituted in cases with substantial bony or soft tissue loss. Revision of the polyethylene-bearing component, coupled with the addition of a yolk-type locking mechanism, was implanted when only the bearing system of a well-fixed implant had failed. TEA can be performed successfully with satisfactory durability as a revision procedure. Revision of failed open reduction internal fixation or a failed bearing system was highly successful. Revision of previously infected elbows in a single-stage procedure was unsuccessful in two of three cases and has been abandoned in favor of a staged procedure. A revision of loose TEA was successful in only three of five cases. Further investigations are necessary to improve the function durability of TEA.
全肘关节置换术(TEA)被用作切开复位内固定失败、三轴关节置换失败以及植入物关节置换术出现感染性和无菌性松动后的挽救手术。使用一种带关节离断阻挡块的微限制性双髁植入物对20例翻修全肘关节置换术进行重建。对于存在大量骨或软组织缺损的病例,则采用定制设计的植入物全肘关节置换术。当固定良好的植入物仅其承重系统出现故障时,更换聚乙烯承重部件并增加蛋黄型锁定机制后进行植入。全肘关节置换术作为一种翻修手术能够成功实施,且耐久性令人满意。对失败的切开复位内固定或失败的承重系统进行翻修非常成功。在单阶段手术中对先前感染的肘关节进行翻修,三例中有两例未成功,现已放弃单阶段手术而采用分期手术。五例松动全肘关节置换术的翻修中仅有三例成功。有必要进行进一步研究以提高全肘关节置换术的功能耐久性。
