Abstract

PROTESIS DE ARTICULACION DE CADERA (10) FEMORAL PARA IMPLANTE POR MEDIO DE CEMENTO CON UNA ESPALDILLA SIN CUELLO EN EL EXTREMO PROXIMO Y UN MANGO (18) QUE DISCURRE EN LINEA RECTA DESDE LA ESPALDILLA HACIA EL EXTREMO DISTANTE (46), REDUCIENDOSE DESDE LA ZONA PROXIMA HACIA EL EXTREMO DISTANTE (46), DONDE EL MANGO (18) MUESTRA UNA SECCION TRANSVERSAL CONFIGURADA DE FORMA TRIANGULAR. LA SECCION TRANSVERSAL DE FORMA TRIANGULAR PUEDE SER TRAPEZOIDAL, RECTANGULAR O CUADRANGULAR Y PASA DESDE LA ZONA PROXIMA DEL EXTREMO DISTANTE (46) DEL MANGO A TRANSFORMARSE EN ESTA OTRA FORMA. EL MANGO (18) MUESTRA ADEMAS UNA SUPERFICIE LATERAL ANTERIOR Y UNA SUPERFICIE LATERAL (28,28'') POSTERIOR, QUE EN LA DIRECCION DE DESARROLLO DEL MANGO (8) MUESTRAN EN UN PRIMER TRAMO PARCIAL (26), QUE COMIENZA POR DEBAJO DE LA ESPALDILLA, UNA CURVATURA QUE DISCURRE DE FORMA LOGARITMICA, Y A CONTINUACION DISCURREN EN UN SEGUNDO TRAMO PARCIAL (32) EN FORMA DE LINEA RECTA Y CONVERGENTE.
