Patent ID: 7582092

Claim:
An assembly tool for assembly of a first component of a prosthesis to a second component of the prosthesis for use in joint arthroplasty, said tool comprising: a first member having a first member angular orientation surface for contact with a first prosthesis component angular orientation surface of a first prothesis component; a second member having a second member angular orientation surface for contact with a second prosthesis component angular orientation surface of a second prosthesis component, said first member and said second member being adapted to provide for the assembly of the first prosthesis component to the second prosthesis component, said second member operably associated with said first member for relative motion therebetween for assembly of the first prosthesis component to the second prosthesis component; and an angular orientation feature cooperating with the first member angular orientation surface of said first member and the second member angular orientation surface of said second member for at least one of replicating and measuring the relative angular orientation of the first prosthesis component with respect to the second prosthesis component, wherein said angular orientation feature includes a first angular orientor and a second angular orientor, wherein said first member and said second member define a longitudinal axis of rotation, wherein said first member is rotatably keyed with the first prosthesis component by said first angular orientor, wherein said second angular orientor is rotatably keyed to the second prosthesis component, wherein the relative angular position of the first prosthesis component with respect to the second prosthesis component about the longitudinal axis corresponds to the angular orientation of the first angular orientor with respect to the second angular orientor; and wherein said first member and said second member are configured to maintain a specific angular relationship between the first member angular orientation surface and the second member angular orientation surface when the assembly tool locks the first prosthesis component to the second prosthesis component; and wherein the assembly tool further comprises a cooperating member for cooperation with the second prosthesis component, said cooperating member cooperating with said angular orientation feature to at least one of replicate and measure the relative angular orientation of the first prosthesis component with respect to the second prosthesis component.
