Abstract: A prosthetic knee system includes a tibial tray, a non-rotating tibial insert, and a rotating tibial insert. The non-rotating tibial insert and the rotating tibial insert are selectively couplable to the tibial tray such that a fixed or a mobile orthopaedic prosthesis may be configured. In some embodiments, the tibial tray may be a fixed or mobile tibial tray. Additionally, in some embodiments, the prosthetic knee system may include a femoral component.

Abstract: Two spacer components and a retaining ring are part of an orthopaedic system. The system may also include trial or implant stem components that are inserted or implanted in the proximal and distal ends of the long bone. One spacer segment has a male portion and the other spacer segment has a transverse female slot. The male portion and female slot are positioned to allow the male portion to be moved into and out of the female slot in a direction other than the proximal-distal direction. The retaining ring is then threaded into a locked position to limit relative movement between the male portion and female slot. The spacer segments can thus be connected after the segments have been connected to the native bone without damaging the soft tissue at the native bone through distraction.

Abstract: An intercalary prosthesis spans a space in the shaft of a long bone between native proximal and distal ends of the long bone. The intercalary prosthesis has first and second intercalary segments connected to proximal and distal stem components. The stem components are implanted in the proximal and distal ends of the long bone. One of the intercalary segments has a male dovetail and the other has a female dovetail. The male and female dovetails are positioned to allow the male dovetail to be moved into the female dovetail in a direction other than the proximal-distal direction. The intercalary segments can thus be connected after the segments have been implanted without damaging the soft tissue at the native bone through distraction. The intercalary segments and stem components are provided as part of a kit. The method of implanting the intercalary prosthesis is also disclosed.

Abstract: A tool, system and method for separating connected orthopaedic components are disclosed. The system includes two orthopaedic components that are connected end to end. One of the orthopaedic components has a notch that receives a cam carried by the tool. The notch and cam are sized and shaped so that when the cam is turned, the cam forces the two components apart. The invention is particularly useful when Morse tapers are used to connect the components. The invention can be used with the modular orthopaedic implants as well as with modular trials used intraoperatively. The cam can be removably mounted on the tool.

Abstract: A comprehensive modular implant system is provided that is especially adapted for limb preservation. The modular components of the system can be combined to perform proximal, distal or total long bone replacement. Each replacement component is connected by a Morse taper engagement. The Morse taper engagement can be augmented by interlocking anti-rotation features between adjacent components. Certain components are configured to form part of a skeletal joint, while other components are configured for engagement within existing portions of the long bone. A number of segmental components operate as spacers for spanning the length of a removed section of bone. Certain segmental components are provided in several lengths, with one group of lengths increasing in 5 mm increments. Combinations of the segmental components can accommodate replacement lengths from 25 mm to 170 mm in 5 mm increments.
