Abstract
Objetivo
Se estudian los casos de disociación del núcleo de polietileno de la copa metálica no cementada Cerafit® (Ceraver-Osteal, Roisy, Francia).
Material y método
Once casos de disociación polietilenocopa metálica, de los cuales en cinco se reconoció un antecedente traumático y en los otros seis una clínica insidiosa.
Resultados
Cuando la clínica se presentó de forma aguda se apreció una luxación del núcleo del polietileno con rotura del mecanismo de anclaje. Mientras que los pacientes con clínica insidiosa presentaron diferentes grados de usura del polietileno y abrasión de la copa metálica con metalosis. En todos los casos se recambiaron el cótilo y el vástago femoral.
Conclusión
La disociación del núcleo de polietileno de la copa metálica es una complicación de la artroplastia total de cadera relativamente rara. Si no se reconoce a tiempo, las consecuencias pueden ser catastróficas.
Aim
To study cases in which there has been disassociation of the polyethylene insert from the Cerafit® (Ceraver-Osteal, Roisy, France) non-cemented metallic acetabular shell.
Materials and methods
Eleven cases were seen of disassociation of the polyethylene liner from the metallic acetabular shell. In five cases there was trauma and the other six had an insidious clinical evolution.
Results
In the cases with acute onset there was dislocation of the polyethylene liner and rupture of the fixation mechanism. In the cases with an insidious clinical evolution, there were different degrees of wear of the polyethylene with abrasion of the metallic acetabular shell and metallosis.
All cases underwent revision with replacement of the acetabular cup and the femoral stem.
Conclusion
Disassociation of the polyethylene liner from the metallic acetabular shell is a relatively rare complication in total hip replacement. But if it is not recognized in time the consequences can be catastrophic.
目的研究非胶结金属杯Cerafit®(cerave - osteal, Roisy,法国)聚乙烯芯的解离案例。材料和方法11例聚乙烯-金属分离病例,其中5例有创伤史,6例有潜伏临床史。在本研究中,我们评估了两种不同的治疗方法,一种是使用聚类锚定机制,另一种是使用聚类锚定机制。然而,临床隐伏的患者表现出不同程度的聚乙烯磨损和金属杯磨损。所有病例均切除股骨和股骨茎。在全髋关节置换术中,聚乙烯核与金属杯分离是一种相对罕见的并发症。如果不及时认识到这一点,后果可能是灾难性的。AimTo研究案例中,从Cerafit®(ceraveri - osteal, Roisy, France)非胶结金属髋关节壳中分离出聚乙烯插入物。材料和methodsEleven cases看到of disassociation of the polyethylene公会from the metallic acetabular shell。五家机构cases创伤was there and the other六或insidious clinical evolution。was dislocation ResultsIn the cases with严重便there of the polyethylene公会and rupture of the fixation机制。= =地理= =根据美国人口普查,这个县的面积为,其中土地面积为,其中土地面积为。All cases underwent订正本with剂of the acetabular杯and the femoral干细胞。shell ConclusionDisassociation of the polyethylene公会from the metallic acetabular is a的rare总人数complication hip剂。但如果不及时认识到这一点,后果可能是灾难性的。
