An orthopaedic surgical instrument system includes a tibial base trial and a tibial insert trial. An insert adaptor is sized to be positioned in an aperture defined in the tibial insert trial. The insert adaptor includes a base sized to be positioned over a post of the tibial base trial and a locking tab positioned in the base and configured to engage the post of the tibial base trial.

A tibial spacer paddle comprises a spacer block comprising opposing bearing surfaces, an alignment slot extending into the spacer block; and a handle extending from the spacer block. The spacer block can include feet for passively engaging the femur or pegs for actively engaging a femoral component so that the spacer block is linked to the femur while the tibia rotates. A tibial spacer system comprises a provisional component having an alignment tab extending from a body and an alignment indicator located on the body, a femoral component and a pin extending from the femoral component. The pin can engage the alignment tab so that the provisional component is linked to the femur while the tibia rotates. In addition to or alternatively to the alignment tab and pin, the provisional component can include a tibial plate that can be rotationally connected to the provisional component.

An improved modular rotational device includes a first and second threaded coupler for affixation along the stem of an endoprosthetic device, for example, a humeral prosthesis or a femoral prosthesis. The rotational device axis of rotation is coaxial with the stem, and its axis of rotation is located in close proximity to the intramedullary stem of the prosthesis or in close proximity to the distal articulation of the prosthesis. A housing has a proximal and distal end with an axial bore therethrough for receiving an elongated stem of the device. A lobe ring may be utilized to limit the axis of rotation of the device. Additional endoprosthetic devices may be attached to male or female threaded couplers, or to Morse tapers. A plurality of suture attachments facilitates attachment of soft tissue thereto.

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.

A bone joint repair and replacement assembly. A first portion comprising a bone plate is configured to attach to a distal or proximal end of a bone proximate the joint, generally coaxially with an axis defined by the bone. A second portion comprising an articular surface is configured to attach to the first portion, generally normal with respect to the axis, and inserted into the joint. Although versions of the assembly can be configured for use with several different pivotal joints, the invention is particularly suitable for full or partial replacement of an elbow, wherein the articular surface is pivotally attached to the first portion. Another embodiment of the invention is provided to repair a fractured bone head proximate the joint, and still another embodiment of the invention is provided to repair rotator cuff-related shoulder injuries.

An orthopaedic prosthesis system includes a femoral component configured to be attached to a distal end of a patient's femur. A tibial tray is configured to be attached to a proximal end of a patient's tibia. A tibial insert is configured to be positioned between the femoral component and the tibial tray. An elongated pin rotatably couples the tibial insert to the femoral component.

A hinged articulating spacer system for revision knee arthroplasty includes a femur rod for a femur, and a tibia rod for a tibia. The tibia rod is hingedly couplable to the femur rod to form a hinged rod assembly. A pre-formed femoral spacer component includes bone cement impregnated with an antibiotic. The pre-formed femoral spacer defines an opening that receives the hinged rod assembly. A pre-formed tibial spacer component includes bone cement impregnated with an antibiotic. The pre-formed tibial spacer defines an opening that receives the hinged rod assembly.

An orthopaedic prosthesis includes a femoral component configured to be attached to a distal end of a patient's femur. A tibial tray is configured to be attached to a proximal end of a patient's tibia. A tibial insert is configured to rotate relative to the tibial tray. A modular insert is received in a cavity defined in the tibial insert. The femoral component is rotatably coupled to the body of the modular insert.
