Abstract
An extra-discal device for intervertebral stabilization includes at least one rigid part connected to pedicle screws by an element. This rigid part comprises a cylindrical body, each end of which is firmly attached to the element which is flexible and deformable so as to be linked to a part of a corresponding pedicle screw with reduced play to obtain a limited range of multidirectional movement in the sagittal, horizontal and frontal planes, while limiting translational movement to the axis of the screw.
Claims10
Extra-discal device for intervertebral stabilization including at least two pedicle screws cooperating with at least two different vertebrae, the screws being linked by a linkage assembly including at least one rigid part coupled to at least one pedicle screw by a loop of an element extending from inside a hollow end of the rigid part, wherein the rigid part comprises a cylindrical body, the element being fixed inside a hollow end of the cylindrical body, and the element being flexible and deformable and linked by the loop to a part of the at least one pedicle screw with reduced play to obtain a limited range of multidirectional movements in sagittal, horizontal and frontal planes while limiting translational movement to an axis of the at least one pedicle screw.
