El cotilo de impactación en las artroplastias de cadera

Abstract

Entre los diferentes sistemas de fijación de la cúpula acetabular entre las artroplastias no cementadas, la impactación tiene múltiples ventajas. Permite un mejor contacto entre implante y hueso y no necesita destrucción de la superficie ósea receptora. Los nuevos diseños para impactación están fabricados en aleaciones de titanio y poseen una superficie rugosa recubierta a su vez con hidroxiapatita. Algunos modelos como la artroplatia Bihapro poseen aletas estabilizadoras en su reborde externo para evitar la movilización rotatoria inicial. El sistema de impactación está mostrando buenos resultados de la experiencia conocida y aunque los periodos de seguimiento son aún cortos, la integración ósea conseguida es satisfactoria. Se presentan los resultados de 1107 cúpulas Bihapro con una evolución entre uno y siete años, que han seguido un protocolo de seguimiento informatizado. En sólo un caso se presentó movilización del componente que precisó cirugía de revisión.

The acetabular fixation by impaction has advantages on other systems of fixing in the cementless arthroplaties of the hip. Permit a better contact between implant and bone and it does not need destruction of the receiving bony surface. The new designs for fixation by impaction are manufactured in titanium alloys and possess a rugged surface cover at the same time with hyrdoxiapatite-coated. Some models as the arthroplasty Bihapro possess fins for primary stability in your external curbing to avoid the initial rotary mobilization. This system of fixation is showing good results in the known experience and though the periods of follow-up are yet short, the obtained bony integration is satisfactory. We presented the results of 117 Bihapro cups implanted with a follow-up from one to seven years, that they have followed a computed protocol. In only a case was presented loosening of the component that specified review surgery.
