Información del artículo
Más del 50% de los casos de caderas inestables se pueden resolver mediante la reducción cerrada de la luxación. Un intento sistemático para entender la causa de la inestabilidad, normalmente suele conducir a un tratamiento eficaz del problema cuando hace falta cirugía. Los componentes constreñidos o de retención han mejorado las posibilidades de resolver los problemas difíciles de inestabilidad, pero los efectos negativos potenciales de estos componentes deben tenerse también en cuenta. Los implantes tripolares, cuyos resultados clínicos en la literatura son muy alentadores, ocupan un lugar de elección en el arsenal terapéutico de la inestabilidad protética.

Over 50% of unstable hip cases can be solved by carrying out a closed reduction of the dislocation. A systematic attempt to understand the cause of the instability, normally results in an efficient treatment of the condition in cases where surgery is required. Constrained – also known as retentive – components have enhanced the possibilities of addressing difficult instability problems, although the potential negative effects of these implants also need to be considered. Tripolar implants, whose clinical results are very encouraging according to the literature, should occupy a prominent place among the therapeutic options available for prosthetic instability.
Key words:
