Abstract

Un fijador externo compacto para el tratamiento de fracturas en huesos pequeños y en niños que comprende un par de sujetadores (2, 3) para pernos de hueso (V), conectados a través de articulaciones de bola (5, 6) correspondientes a un cuerpo central (4) que comprende por lo menos un miembro macho (7) y un miembro hembra (8), los cuales están unidos telescopicamente. Un miembro (7) se hace de un material el cual es altamente transparente a los rayos X, el otro miembro (8) de un material rígido sustancialmente radio-opaco que tiene paredes de un espesor mínimo. Se proporciona medios contra la rotacion entre el miembro macho (7) y el miembro hembra (8) telescopicos; se alojan pasadores excéntricos transversales (34, 35) en cada sujetador para actuar sobre los bloques de cierre (28, 29) correspondiente, los cuales inmovilizan las bolas (24, 25) de las articulaciones. Un dispositivo de tension (36) aplicable al fijador (1) comprende formaciones de gancho (49, 50), las cuales pueden ser acopladas a los extremos de los miembros telescopicos (7, 8) y están unidas a los extremos de las barras roscadas encontradas (43, 44) atornilladas en las porciones roscadas de un manguito giratorio (37). El fijador permite el examen completo a través de rayos X de la fractura aun a través del cuerpo central, y es ligero y pequeño como resultado de la disposicion de los medios de bloque para las articulaciones dentro de los sujetadores.
