An orthopedic system for delivery of a therapeutic agent to a bone includes an elongate stem adapted to be inserted into an intramedullary canal, an inlet configured to receive the therapeutic agent, and one or more outlets configured to deliver the therapeutic agent to the bone. The elongate stem may comprise one or more protrusions to engage the bone, and one or more channels extending longitudinally therein, fluidly coupled to the inlet. The therapeutic agent flows from the inlet through the one or more channels and exits into the intramedullary canal through the one or more outlets. The system may be configured to allow one or more dimensions of the system to be adjusted to accommodate the anatomy of a patient.

A system and method for improving upon an ability of a surgeon to repair traumatic bone injury using new materials, components, and structures. A structure may be used as an implant or a component of an external fixator for a fractured long bone with that structure having anisotropic and viscoelastic properties, such as through additive manufacturing techniques.

An acetabular implant kit includes a first acetabular component that has an inner surface that defines a first concave profile. A second acetabular component includes an inner surface that defines a second concave profile. An instrument includes an elongated body that has a first end and a second end. A head is connected to the second end of the body and has an engagement surface. The engagement surface includes a first convex profile and a second convex profile. The first and second convex profiles are arranged along a longitudinal axis of the head and have a first radius of curvature configured to congruently engage the first concave profile of the first acetabular component. The second convex profile has a second radius of curvature configure to congruently engage the second concave profile of the second acetabular component. The first radius of curvature is different than the second radius of curvature.

A surgical implant system includes an implant and a fixation member for securing the implant to tissue. The implant and the fixation member together comprise a single monolithic structure. The implant includes an insertion instrument. The implant, the fixation member, and the insertion instrument together comprise a single monolithic structure and are constructed from a single material. The implant is monolithically connected to the fixation member at a first frangible connection and is monolithically connected to the insertion instrument at a second frangible connection. Each of the frangible connections can be broken when force is applied.

Multi-hooded enarthrodial joint implant has a hard substance articulating cup including a hard substance head-receiving cup having an articular surface upon which a head of a joint can articulate, and which, in general, has a margin generally about a hemisphere more or less and at least two hoods that are marginally extended continuations of superior one-half or so of cup containment of a sufficient magnitude to reduce an overall dimension of socket outlet to less than a hemisphere, which can embrace and contain the head. The head is made of a hard substance and has a truncated generally circular cross section, a truncated surface with a feature for attachment of the stem, and an opposing articular surface for articulation against the articular surface of the ceramic head-receiving cup. As an ensemble, the cup is combined with the head, typically with a stem, for a total joint implant. The hard substance may be, for example, a composite substance, a metal or a metal alloy. Either the cup or the head, but not both, may be ceramic when employed in an ensemble.

A hip implant is provided that includes a metal acetabular cup to be inserted into an acetabulum of the pelvis, a femoral head and neck portion with a polymer femoral head molded onto a metal formal head base that is attached to a metal femoral neck rod configured to be inserted into the neck of a femur, and a metal main body shaft configured to be inserted into a femoral shaft region of the femur and secured by bone screws. The head base may have stabilizing features, such as dimples and peripheral mounds, over which the femoral head is molded. The main body shaft also has diagonal hole located at the center line of the neck of the femur to receive the femoral neck rod at an adjustable angle. The femoral head interfaces with the acetabular cup as a smooth plastic-to-metal spherical-surface joint.
