Abstract:
An implant system includes a first portion, a second portion, and a third portion. The first portion includes a hydrogel. The second portion includes a porous material and the hydrogel in pores of the porous material. The third portion includes the porous material. The first portion is free of the porous material. The third portion is free of the hydrogel. Methods of making and using the implant system.
Abstract:
An intervertebral spacer (300) having an upper layer (302), a lower layer (306) and at least one non-planer compliant layer (304). The non-planer compliant layer is disposed between the lower layer and the upper layer and includes a portion that extends outside a lateral plane in which the compliant layer resides. The non-planar compliant layer made of a material that is more yielding than the upper layer and the lower layers, and may have a cross-section that is z-shaped, u-shaped, sinusoidal-shaped, zigzag shaped, etc.
Abstract:
An orthopedic implant comprises an implant configured to support a first bone segment relative to a second bone segment. The implant is comprised of a material having an elastic modulus of approximately 40 GPa and a tensile strength of at least approximately 1000 MPa. In embodiment, the implant is comprised of GUMMETAL®.
Abstract:
The present invention is directed to a surgical implant for the fusion of two adjacent vertebrae with an upper plane for contacting an upper vertebral body and a lower plane for contacting a lower vertebral body and a tubular structure, wherein the tubular structure is formed by a plurality of tubes running from the upper plane to the lower plane and in substantially horizontal direction throughout one side of the surgical implant straight to the opposite side of the surgical implant. This tubular structure has the advantage that the formation and ingrowth of new bone is promoted and advantaged and that the degree of formation and ingrowth of new bone is detectable by X-ray measurements.
Abstract:
The invention relates to intervertebral disk implants which imitate the natural degrees of freedom of movement by allowing translational and/or rotational movements of the disk located between the vertebrae relative to the bottom plate independently of the possible movements of the cover plate relative to said disk located between the vertebrae. Said movements can be performed by mounting the disk located between the vertebrae on the bottom plate by means of fastening means disposed inside the implant in such a way that translational and/or rotational movements are made possible. Furthermore, the contact surface between the cover plate and the disk located between the vertebrae is semi-cylindrical such that the contact surface is maximized.
Abstract:
A method for producing, on the surface of manufactured articles made of metal, such as for example dental and orthopedic prostheses, a macrostructure and a microstructure, wherein the macrostructure is capable of facilitating the mechanical coupling of the implant and the regrowth of mature trabecular bone structures and the microstructure is capable of facilitating the engagement, at the chemical and physical level, of the surface of the implant by stimulating the osteoinductive/osteoconductive processes of bone tissue. The method comprises the steps of: applying a mask to a metal article; selectively removing part of the mask by means of a computerized system and a laser; applying an electrochemical cycle to remove the exposed material of the article. The electrochemical cycle provides for the application of an electrochemical scanning cycle, which allows to identify the correct working potential and then the application of an electrochemical cycle at constant potential in the work area identified by means of the preceding cycle; removing the remaining mask; generating chemically or electrochemically a micro-rough and/or microporous surface.
Abstract:
A method of treating a patient includes determining a patient characteristic associated with the patient, determining a property value based at least in part on the patient characteristic, and determining a crosslinking parameter based at least in part on the property value.
Abstract:
The present invention relates to a new composition and medical implant made therefrom, the composition comprising a thick diffusion hardened zone, and preferably further comprising a ceramic layer. The present invention relates to orthopedic implants comprising the new composition, methods of making the new composition, and methods of making orthopedic implants comprising the new composition.
Abstract:
A surface-modified implant comprising a plurality of nanotubes and a process for preparing the surface-modified implant. The metal-containing surface of the implant is modified using an electrochemical anodization process to create a plurality of nanotubes formed of an oxide of the metal on at least a surface of the implant.
Abstract:
Described herein are methods for testing an aged surface on an implant, methods for regenerating a hydrophilic and osteophilic surface on the implant and kits therefor.
