20120022662 | IMPLANT COMPONENTS AND METHODS - 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. | 01-26-2012 |
20120215310 | POROUS IMPLANT STRUCTURES - 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 has 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, portions that are curved and/or straight. The struts and nodes can form cells which 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. | 08-23-2012 |

20120321878 | CONTROLLED RANDOMIZED POROUS STRUCTURES AND METHODS FOR MAKING SAME - 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. | 12-20-2012 |
20140066937 | PATIENT SPECIFIC IMPLANT POSITIONING - Instrument that is made to match the perimeter shape of a Patient Specific Knee Implant (PSKI) with features for locating holes in the distal femur such that the posts or lugs in the femoral implant locate the femoral implant centered medial-laterally within an acceptable degree of precision to prevent overhang of either the medial or lateral side of the femoral implant over the perimeter of the distal femur bone resections. Patient specific implant technology, in which a three-dimensional model of at least a portion of a bone is accessed and a three-dimensional solution volume is defined based on resection cuts used in fitting an implant on the portion of the bone. An outline representation of at least a portion of an outer surface of a periphery of the resultant bone volume is determined and the outline representation is used in one or more operations related to instrument matching. | 03-06-2014 |

20140244220 | SYSTEMS AND METHODS FOR OPTIMIZING FIT OF AN IMPLANT TO ANATOMY - A system and method for pre-operatively optimizing a fit of an orthopaedic implant relative to a particular individuals anatomy is provided. The method includes: receiving information including a three-dimensional anatomic model of the individuals anatomy; computing a periphery of a simulated resection portion of the anatomic model without reference to any abnormal morphology; identifying a preliminary size for an orthopaedic implant component for use on the simulated resection surface; initially positioning the orthopaedic implant model relative to the simulated resection portion; generating random point sets around the peripheries of the simulated resection portion and the orthopaedic implant model; utilizing a position optimizer to determine whether the position of the orthopaedic implant periphery relative to the simulated resection portion periphery is optimal; determining whether the selected orthopaedic implant model results in overhang; and verifying the position of the orthopaedic implant and/or the size of the orthopaedic implant. | 08-28-2014 |
20150032218 | COMPLIANT ANTI-RESORPTION IMPLANT - 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 Carticulation 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. | 01-29-2015 |
20150073562 | TIBIAL IMPLANT HAVING AN ANATOMIC STEM - Disclosed herein are systems, methods, and devices for providing a tibial implant including an anatomic stem that provides a close interface between the implant and surrounding bone. The stem varies in size, cross-sectional shape, or orientation from a proximal portion of the stem to the tip of the stem. The variation of the stem accommodates the variation of tibial anatomy into which the implant component is implanted. The stem provides resistance against rotation of the implant and reduces stress shielding effects by transmitting forces into surrounding bone. In certain implementations, the interface between the stem and bone is supplemented by fin extensions that extend outward from the stem and increase the contact between the implant and the surrounding bone structure. | 03-12-2015 |
