Abstract

Mejoras introducidas en los componentes femoral y pelviano de las prótesis de cadera. El componente femoral de una prótesis de cadera, está materializado por una pieza metálica que ha de introducirse por el interior del hueso del fémur (6), emergiendo al exterior un cuello troncocónico (1) rematado en una cabeza protésica (4) que juega en el cotilo del implante de la cadera, o en el propio hueso de la pelvis. Las mejoras consisten en formar una barrera de tejidos vivos adherida de una parte al fémur y de otra a la zona que rodea al implante, evitando así que las partículas que puedan formarse por desgaste del juego, puedan pasar al interior del fémur, con los efectos adversos que ello ocasionaría. El cuello (1) del componente femoral (2), posee al menos una zona o banda perimetral (3) no pulida, provista de un recubrimiento biocompatible que facilita la adhesión de los tejidos femorales, sellando el acceso al interior del mismo. También puede utilizarse un collarín (8), fijado mediante un anillo (9) al cuello (1) y con el borde libre ajustado por el exterior del fémur, o bien, una cápsula articular (14) tendida entre el cuello (1) y el cotilo (16).Improvements introduced in the femoral and pelvic components of hip prostheses. The femoral component of a hip prosthesis, is materialized by a metal piece that has to be introduced inside the bone of the femur (6), emerging from the outside a truncated conical neck (1) finished off in a prosthetic head (4) that plays in the cup of the hip implant, or in the pelvic bone itself. The improvements consist in forming a barrier of living tissues adhered from one part to the femur and from another to the area surrounding the implant, thus preventing particles that can be formed by wear of the game, can pass into the femur, with the effects adverse that this would cause. The neck (1) of the femoral component (2), has at least one area or perimetral band (3) not polished, provided with a biocompatible coating that facilitates the adhesion of the femoral tissues, sealing access to the interior thereof. A collar (8) can also be used, fixed by means of a ring (9) to the neck (1) and with the free edge adjusted on the outside of the femur, or an articular capsule (14) lying between the neck (1) and the cup (16).
