A system includes a first implant component and a second implant component. The first implant component is configured to be secured to a bone and includes a plate and a coupler extending upward from the plate and defining a coupler axis. The second implant component is configured to be coupled to the first implant component. The second implant component includes an articulation surface and defines a cavity configured to receive the coupler of the first implant component. The second implant component is couplable to the first implant component at a plurality of rotational orientations about the coupler axis.

An apparatus includes a body extending from a first end to a second end. The first end is a leading end, and the second end includes a first coupling element configured to couple the body to a first other component. The body includes an external fixation element extending along a length of the first component. The external fixation element is configured to engage bone. Systems and methods are also disclosed.

An orthopaedic prosthetic component is provided. The orthopaedic prosthetic component comprises a porous three-dimensional structure shaped to be implanted in a patient's body. The porous three-dimensional structure comprises a plurality of unit cells. At least one unit cell comprises a first geometric structure having a first geometry and comprising a plurality of first struts, and a second geometric structure having a second geometry and comprising a plurality of second struts connected to a number of the plurality of first struts to form the second geometric structure.

The present invention disclosed a method of producing a three-dimensional porous tissue in-growth structure. The method includes the steps of depositing a first layer of metal powder and scanning the first layer of metal powder with a laser beam to form a portion of a plurality of predetermined unit cells. Depositing at least one additional layer of metal powder onto a previous layer and repeating the step of scanning a laser beam for at least one of the additional layers in order to continuing forming the predetermined unit cells. The method further includes continuing the depositing and scanning steps to form a medical implant.

A medical implant for treating bone defects. The implant has at least one hollow body delimiting an inner chamber in the interior of the hollow body, a fluid feed line connected in a fluid-permeable manner with the inner chamber, and a fluid discharge line connected in a fluid-permeable manner with the inner chamber. The hollow body consists at least in places or wholly of at least one plastic material that is impermeable to liquids and permeable to oxygen and to carbon dioxide, such that oxygen is deliverable from a fluid passed through the hollow body to, and carbon dioxide is absorbable into the fluid from, the surroundings of the hollow body. Also disclosed is a bone defect treatment system having such a medical implant and the fluid, wherein the fluid contains oxygen and is suitable for absorbing oxygen, and to a method for gas-flushing a surface of a medical implant.

A system of prosthetic implants for a total knee replacement procedure is provided. The system includes a tibial component of a knee joint implant, a tibial insert configured to be positioned against the superior side of the platform of the tibial component, a first femoral component of a knee joint implant, and a second femoral component of a knee joint implant.

The present invention relates to an animal femoral implant and, more specifically, to an animal femoral implant, which may enable artificial hip joint replacement for animals, may enable the implant to be firmly fixed to the animal femur by spontaneous bone growth of the animal, thereby preventing complications such as aseptic dissociation and bone resorption around the cement, which may occur when using bone cement, and may cause a porous part, which has relatively low strength due to a plurality of pores formed therein, to be protected by a frame part, which has relatively high strength due to a solid face formed therein, thereby preventing damage to the porous part in which the edge thereof is broken or bent by friction with the bone or by an external force in the process of inserting the femur implant into the animal femur and eliminating a problem in that porous particles that may be generated when the porous part is damaged penetrate into blood vessels and the like to cause various inflammatory reactions.

An extraction tool for removing an installed artificial disc from a spine is provided. The extraction tool is impacted between the artificial disc and the vertebrae and engages the artificial disc to allow a surgeon to remove the artificial disc from the spine.

Disclosed is a method for forming an orthopaedic implant. The method comprises determining one or more parameters of a bone, of a subject, to which the implant is to be attached, and calculating specifications based on parameters. That calculation includes calculating a mechanical property relating to elasticity of the implant, a length of the implant, and positions of two or more fixation locations by which to fix the implant to the bone. The method further comprises forming the implant based on the specifications, wherein each fixation location comprises a longitudinal axis through the implant, and calculating specifications comprises calculating a trajectory for the longitudinal axis of the respective fixation location.

The shim-type implant for distraction and fusion of cervical facet joints is provided. The implant has a generally box-like shape with a blunt leading edge that may be centered or offset to the inferior face. The implant may include a graft window for enhanced osseous through-growth after implantation. The implant is coated with hydroxyapatite (HA) and/or tri-calcium phosphate (TCP) to allow for osteo-conduction, is porous, and has a roughened surface with serrations on the superior and inferior faces. The implant may be fabricated from a titanium or tantalum alloy. In an embodiment, a set of tools is provided with a chisel and one or tongs and one or more decorticators for inserting the implant.
