摘要： A method of generating a custom three-dimensional model of a bone is disclosed. A 2D image of the bone is obtained and an orientation and scale of the 2D image are aligned to a pre-determined coordinate system. Based on the 2D image, a representative bone is identified from a library of representative bones that are aligned to the pre-determined coordinate system. Based on the 2D image, an ideal view of a 3D model of the representative bone is selected. Modifications may be made to the 3D model by using additional representative bones from the library. A custom three-dimensional model of the bone is thereby generated.

摘要： Improved randomized porous structures and methods of manufacturing such porous structures are disclosed. The scaffold of the porous structures are formed from by dividing the space between a plurality of spatial coordinates of a defined volume, where the plurality of spatial coordinates have been moved in a random direction and a random finite distance according to a predetermined randomization limit.

摘要： Porous biocompatible structures suitable for use as medical implants and methods for fabricating such structures are disclosed. The disclosed structures may be fabricated using rapid manufacturing techniques. The disclosed porous structures each have a plurality of struts and nodes where no more than two struts intersect one another to form a node. Further, the nodes can be straight, curved, and can include portions that are curved and/or straight. The struts and nodes can form cells that can be fused or sintered to at least one other cell to form a continuous reticulated structure for improved strength while providing the porosity needed for tissue and cell in-growth.

摘要： Method, system, and program products are disclosed herein for creating a 3D model based on a plurality of received 2D medical images. Once the 2D images are received, a determination is made regarding any potential processing steps required to put the images into a standard view. Once the images are processed, a plurality of points are identified that are associated with a portion of an anatomical landmark. Various historical 2D images are then identified based on a comparison between the plurality of points. Using the historical information, a 3D image is generated of an anatomical feature of a patient.

摘要： Systems, devices, and methods are described for providing orthopedic implants that reduces the negative effects of stress shielding on surrounding bone structure. The orthopedic implants are comprised of two portions, a shell portion that forms an articulation interfaces and an intermediate portion that forms a bone interface. The shell portion is designed to reduce absorption of articulation forces and evenly distribute incident forces to the intermediate portion. The intermediate portion is designed to form a strong interface with native bone and transmit forces from the shell into the bone.

摘要： 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.
