An adjustable spacer modular device for the treatment of an articulation of the human body, comprising a fitting central body provided with an end having a substantially flat first surface, a head adapted to be arranged within an articular cavity, wherein the head comprising a cap and a base opposite to said cap, wherein the cap and the base are radiused to each other, a rod-like element, adapted to be fixedly connected at a bone end, first means for connecting the head to the central body, wherein the first connection means are adjustable and adapted to adjust the inclination of the head with respect to the central body along a longitudinal plane and/or along a transverse plane of the human body.

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 femoral stem for use in hip replacement surgery, specifically hip replacement surgery in dogs and similar animals but also inclusive to implants used in humans. More particularly, the invention is directed to a femoral stem that includes a lateral bolt or post that protrudes through the cortex or wall of bone opposite the neck of the femoral stem. The lateral bolt or post reduces the occurrence of subsidence in implanted femoral stems. The lateral bolt or post provides an anchor point on the cortex or wall of bone as opposed to relying solely on the compression of the femoral stem against the wall of the bony canal of the femur being implanted.

A method of assembling a mobile bearing acetabular component of a prosthetic hip joint is disclosed. The method includes mounting an acetabular cup insert to an acetabular cup. The method includes concurrently repositioning the acetabular cup insert deeper into an interior of the acetabular cup and repositioning the acetabular cup insert outside of an outline of the acetabular cup.

A trial neck for hip surgery and a method of attaching a trial neck to a femoral canal implement. The trial neck includes a body portion including a bore for receiving a proximal end of a femoral canal implement. The trial neck also includes an elongate neck extending from the body portion. The trial neck further includes a locking mechanism comprising a lever. The lever has a first end. The lever also has a second end. The lever further has an engagement surface. The second end of the lever is actuable to urge the engagement surface against the proximal end of the femoral canal implement to secure the proximal end of the femoral canal implement within the bore.

A joint implant component (1, 1; 101; 201) for administering a pharmaceutical product is disclosed, which comprises an implant shaft (10, 10; 110; 210), a joint section (20, 20; 120; 220) arranged at the proximal end of the implant shaft, a flush supply opening (3, 3; 103; 203) and a backflush opening (4, 4; 104; 204). At least one shaft flush channel (11, 11; 111; 211) and one shaft backflush channel (12, 12; 112; 212) extend along the implant shaft inside the implant shaft. The shaft flush channel is connected to the outside of the implant shaft via shaft flush holes (13, 13; 112; 113) for discharging the pharmaceutical product, and the shaft backflush channel is connected to the outside of the implant shaft via at least one shaft backflush hole (14, 14; 114; 214) for receiving the discharged pharmaceutical product. The flush supply opening is fluidically connected to the proximal end of the shaft flush channel and the backflush opening is fluidically connected to the proximal end of the shaft backflush channel. Also disclosed is a joint implant comprising two such joint implant components which are connected to one another by means of joint surface parts (30, 40; 230) and are pivotable relative to one another.
