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.
Claims17
An orthopaedic system comprising:
- a first orthopaedic component;
- a second orthopaedic component capable of being connected to the first orthopaedic component in a longitudinal end to end relationship;
- at least one of the orthopaedic components having an open-ended notch;
- and
- a disassembly tool for separating the connected first and second orthopaedic components, the disassembly tool including a cam;
- wherein the notch is sized and shaped to receive the cam when the first and second components are connected;
- and
- the cam is rotatable in the notch to cause relative longitudinal movement between the first and second orthopaedic components for separation of the first and second orthopaedic components.
