Abstract
Systems, devices, and methods are provided for orthopedic implants. The implants may include a base member, such as an acetabular shell or an augment, that is configured to couple with an augment, flange cup, mounting member, or any other suitable orthopedic attachment. Any of the implantable components may be include one or more porous surfaces. The porous surface may be textured by protrusions that connect to and extend from the surface. The sizes and concentration of the protrusions may be varied for specific applications to accommodate different implants and patient anatomies. A porous implant may also include one or more internal or external solid portions that strengthen the implant.
Claims20
A method for preparing an implantable orthopedic device, the method comprising:
- providing a mold having a negative impression of a porous beaded surface;
- providing an implant substrate to be coated;
- interposing particles between the implant substrate and the mold;
- and
- applying a pressure or elevated temperature to the mold, implant substrate, and particles to create an implant having a surface that matches the porous beaded surface of the mold and is formed from the interposed particles.
A method for preparing an implantable orthopedic device, the method comprising:
- creating, with a processor, a three-dimensional model simulating an outer surface profile of a porous beaded implant;
- creating, with the processor, a three-dimensional model of an implant substrate volume;
- applying, with the processor, the three-dimensional model simulating an outer surface profile of a porous beaded implant to the three-dimensional model of an implant substrate volume to create a pre-form volume;
- applying, with the processor, an algorithm to fill the pre-form volume with a desired reticulated structure to create a porous implant model;
- and
- forming an implant using the porous implant model.
A method for preparing an implantable orthopedic device, the method comprising:
- providing a mold of an implant having an inner surface mimicking a negative image of an outer surface profile geometry of a porous beaded surface;
- providing a plurality of particles;
- placing the plurality of particles into the mold;
- and
- applying a pressure or elevated temperature to the mold to form a surface that matches the porous beaded surface of the mold and is formed from the plurality of particles.
A method for preparing an implantable orthopedic device, the method comprising:
- providing a mold of an implant having an inner surface mimicking a negative image of an outer surface profile geometry of a porous beaded surface;
- loading one or more foaming agents into the mold;
- creating a porous foam component in the general shape or size of the implant, the implant having an outer surface geometry mimicking an outer surface profile geometry of a porous beaded surface;
- removing the porous foam component from the mold;
- applying a binding agent to the porous foam component;
- applying a plurality of symmetric or asymmetric particles to the porous foam component having the binding agent thereon;
- subjecting the porous foam component having the binding agent and particles thereon to an elevated temperature to sinter the particles together and burn out the foam component to form an implant, the implant having a roughened porous texture with an outer surface profile geometry mimicking a clinically-proven porous beaded structure.
