Abstract

LA INSTRUMENTACION COMPRENDE PARA CADA VERTEBRA LUMBAR (L5), DOS TORNILLOS PEDICULARES (1) TENIENDO DOS ROSCAS DE TORNILLO, (9, 11), CORRESPONDIENDO UNA (9) DE LAS ROSCAS DE TORNILLO A LA REGION DE PENETRACION DEL TORNILLO EN EL PEDICULO, DOS VARILLAS (2) TENIENDO ASPEREZAS RESPECTIVAMENTE ASOCIADAS CON UN TORNILLO PEDICULAR Y ASEGURADO AL ULTIMO POR ELEMENTOS DE CONEXION (3) PROVISTO CON ELEMENTOS PARA AMORDAZAR LAS VARILLAS. CADA ELEMENTO DE CONEXION (3) ESTA EN UNA PIEZA Y LA ROSCA DE TORNILLO (9) CORRESPONDIENTE A LA REGION DE PENETRACION DEL TORNILLO EN EL PEDICULO TERMINA EN UN BOMBRO ANULAR (16) CONTRA EL CUAL EMPUJA EL ELEMENTO DE CONEXION EL QUE ESTA SEPARADO POR UNA PARTE LISTA (15) DE LA ROSCA DE TORNILLO (11) FUERA DE LA REGION DE PENETRACION EN EL PEDICULO. ESTA INSTRUMENTACION PERMITE RETORNAR LA VERTEBRA CORRIDA HACIA ATRAS Y PIVOTEARLA EN LA DIRECCION DE ROTACION DESEADA, SIENDO POSIBLE LLEVAR A CABO LA ACCION DE ROTACION LENTAMENTE Y CONTROLANDO EL MOVIMIENTO DE M ANERA QUE EL CIRUJANO OBTENGA EN GENERAL EN LOS DOS MOVIMIENTOS UNA EXCELENTE PRECISION EN LA REPOSICION DE LA VERTEBRA EN RELACION A LAS VERTEBRAS VECINAS.THE INSTRUMENTATION INCLUDES FOR EACH LUMBAR VERTEBRA (L5), TWO PEDICULAR SCREWS (1) HAVING TWO SCREW THREADS, (9, 11), CORRESPONDING ONE (9) OF THE SCREW THREADS, IN THE SCREW PENETRATION REGION TWO RODS (2) HAVING RUGGES RESPECTIVELY ASSOCIATED WITH A PEDICULAR SCREW AND LAST SECURED BY CONNECTION ELEMENTS (3) PROVIDED WITH ELEMENTS TO CLAMP THE RODS. EACH CONNECTION ELEMENT (3) IS IN ONE PIECE AND THE SCREW THREAD (9) CORRESPONDING TO THE REGION OF PENETRATION OF THE SCREW IN THE PEDICLE ENDS IN AN ANNULAR BULB (16) AGAINST WHICH THE CONNECTION ELEMENT PUSHES WHICH IS SEPARATED FOR A LISTED PART (15) OF THE SCREW THREAD (11) OUTSIDE THE REGION OF PENETRATION IN THE PEDICLE. THIS INSTRUMENTATION ALLOWS TO RETURN THE VERTEBRA RUN BACKWARDS AND PIVOT IT IN THE DESIRED DIRECTION OF ROTATION, BEING POSSIBLE TO CARRY OUT THE ACTION OF ROTATION SLOWLY AND CONTROLLING THE MOVEMENT IN GENERAL THROUGH THE SURGEON IN GENERAL IN THE TWO REPLACEMENT OF THE VERTEBRA IN RELATION TO NEIGHBORING VERTEBRAS.
