Abstract

UNA PROTESIS FEMORAL DE LA JUNTA DE LA CADERA TIENE UNA VARILLA (2), CUYO EXTREMO PROXIMAL (6) TIENE UNA SECCION TRANSVERSAL DE FORMA OVAL Y UN AREA SUPERFICIAL QUE AUMENTA HACIA EL EXTREMO PROXIMAL. AL MENOS UNA PARED DEL EXTREMO PROXIMAL TIENE ALVEOLOS (9) EN EL INTERIOR ABIERTOS HACIA FUERA PARA PRESENTAR UNA PROFUNDIDAD MAXIMA EN SU LADO HACIA EL EXTREMO PROXIMAL. LOS ALVEOLOS TIENEN UNA FORMA CIRCULAR O SEMICIRCULAR Y SE CRUZAN ENTRE SI, PROPORCIONANDO DE ESTE MODO UNA SUPERFICIE QUE MEJORA LA ESTABILIDAD Y LA FIJACION DE LA PROTESIS EN EL FEMUR.
