IMPROVED SPINAL FUSION IMPLANTS AND TOOL FOR INSERTION

摘要

A vertebral-column device that is suitable to be received in an intervertebral space between two dorsal vertebrae, said prosthesis comprising a curved strip of biocompatible material and the width of said strip being such that after placement said strip makes contact with the aforementioned vertebrae, the strip being manufactured from a material that can undergo great deformations before permanent deformation arises, and the strip being curved in a shape in which the extremities are situated apart from one another and the radius of the curved parts and the thickness of the strip being chosen in such a way that when the strip is bent out into an approximately straight strip scarcely any permanent deformation arises, in which case the strip which has been bent out into an approximately straight strip is capable of being introduced into an intervertebral space where the strip assumes its original curved shape.
