Title
(EN) PATIENT-SPECIFIC SPINAL IMPLANTS
(FR) IMPLANTS RACHIDIENS SPÉCIFIQUES AU PATIENT
Abstract
(EN)
A spinal implant device comprising a frame and a plurality of mechanical stiffness members extending from the frame, with the plurality of mechanical stiffness members being individually customized to provide a specific axial stiffness. The plurality of mechanical stiffness members may be coupled to the frame, and the plurality of mechanical stiffness members may be a plurality of wave-spring modules. A method of treating spinal disease includes determining actual spatial mechanical properties across a vertebral contact surface of a vertebra of a patient. The method may also include manufacturing a spinal implant device that has conforming spatial mechanical properties that are specific to the patient and that are based on the actual spatial mechanical properties of the vertebral contact surface. The method may include surgically implanting the spinal implant device against the vertebral contact surface such that the actual spatial mechanical properties and the conforming spatial mechanical properties align.

La présente invention concerne un dispositif d'implant rachidien comprenant une armature et une pluralité d'éléments de rigidité mécanique s'étendant à partir de l’armature, la pluralité d'éléments de rigidité mécanique étant individuellement personnalisés pour fournir une rigidité axiale spécifique. La pluralité d'éléments de rigidité mécanique peuvent être accouplés à l’armature, et la pluralité d'éléments de rigidité mécanique peuvent être une pluralité de modules de ressort ondulé. Un procédé de traitement d'une maladie de la colonne vertébrale consiste à déterminer les propriétés mécaniques spatiales réelles à travers une surface de contact vertébral d'une vertèbre d'un patient. Le procédé peut également comprendre la fabrication d'un dispositif d'implant rachidien qui présente des propriétés mécaniques spatiales conformes qui sont spécifiques au patient et qui sont fondées sur les propriétés mécaniques spatiales réelles de la surface de contact vertébral. Le procédé peut comprendre l'implantation chirurgicale du dispositif d'implant rachidien contre la surface de contact vertébral de telle sorte que les propriétés mécaniques spatiales réelles et les propriétés mécaniques spatiales conformes s'alignent.
