Title
(EN) ORTHOPEDIC STIFFENING DEVICE
(FR) DISPOSITIF DE RAIDISSEMENT ORTHOPÉDIQUE
Abstract
(EN) A stiffening device useful for orthopedic stabilization assemblies. The present disclosure provides an apparatus and methods for stiffening the rods and screws typically used for correction of orthopedic defects, such as curvature of the spine. An out-of-plane stiffener is attached to the rods and screws in a plurality of locations, thus reducing the tendency of the rods to move. A stiffener is located in a plane posterior to the rods and screws. The stiffener connects to the rods with adjustable but rigid connections and prevents the rods from bending in the sagittal and coronal planes. This prevents rotation and twisting of the rods and thus the vertebrae into which they are implanted. The stiffeners of the present disclosure may also be attached to pedicle screws only. This helps to correct lordosis and kyphosis bending, as well as scoliosis-type bending. The stiffeners may also be used for cranial and facial applications.
(FR) La présente invention concerne un dispositif de raidissement utile pour des ensembles de stabilisation orthopédique. La présente invention concerne un appareil et des procédés de raidissement des tiges et des vis classiquement utilisées pour la correction de défauts orthopédiques, tels que la courbure de la colonne vertébrale. Un raidisseur hors-plan est fixé aux tiges et aux vis en une pluralité d'emplacements, réduisant ainsi la tendance des tiges à se déplacer. Un raidisseur se trouve dans un plan postérieur aux tiges et aux vis. Le raidisseur raccorde les tiges à des raccords ajustables mais rigides et empêche les tiges de fléchir dans les plans sagittal et coronal. Ceci empêche la rotation et la torsion des tiges et ainsi des vertèbres dans lesquelles elles sont implantées. Les raidisseurs de la présente invention peuvent également être fixés à des vis pédiculaires uniquement. Ceci permet de corriger les courbures lordotiques et cyphotiques, ainsi les courbures de type scoliose. Les raidisseurs peuvent également être utilisés pour des applications faciales et crâniennes.
