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. Mounting members include, for example, flanges, blades, hooks, and plates. In some embodiments, the orthopedic attachments may be adjustably positionable about the base member or other attachments, thereby providing modularity for assembling and implanting the device, and various securing and/or locking mechanisms may be used between the components of the implant.

Abstract: 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.

Abstract: Systems and methods to provide patient-specific cutting blocks that allow for bone resurfacing procedures, such as milling or burring, with simplified devices. A computer assisted surgical cutting block is produced having a surface region that matches with the surface region of a patient's bone to be altered. A cutting tool may be provided having a contoured bone mating surface and a contoured and patient-specific shaped cutting guide surface located in a plane above the bone mating surface. One or more channels are provided in the cutting block, and as the surgeon moves the cutting tool (a milling or burring, for example) in the channels, the tool cuts the bone both laterally along the surface of the bone and vertically into the bone according to the cutting guide surface and other preselected surface features of the cutting block.

Abstract: A retractor element includes a rigid slide connected between a latch bolt and a solenoid plunger for movement between a first position and a second position, the slide operably connected to plunger. A pivoting link defines a slot having an inner end portion extending transversely, the slot configured for pivoting the link when the slide moves between the first position and the second position of the slide. When the retracting mechanism is energized the plunger retracts causing movement of the slide to the second position of slide and the pin to enter the transverse end of the slot in the link. A bearing surface intersects the path of movement of the pin such that significantly less current is required for retaining the plunger in the retracted position than to retract the plunger for blocking the return of the latch bolt to the projected position.
