An assembly tool for assembly of a first component of a prosthesis to a second component of the prosthesis for use in joint arthroplasty. The tool includes a first member operably associated with the first component and a second member operably associated with the second component. The second member includes a cap having a threaded recess and further includes a threaded rod adapted to engage the threaded recess so as to move the second member relative to the first member and the threaded rod is made of a harder metal than the threaded recess.

An assembly tool for assembly of a first component of a prosthesis to a second component of the prosthesis for use in joint arthroplasty, the tool comprising: a first member operably associated with the first component; and a second member operably associated with the second component; wherein th
1. An assembly tool for assembly of a first component of a prosthesis to a second component of the prosthesis for use in joint arthroplasty, the tool comprising: a first member operably associated with the first component; and a second member operably associated with the second component; wherein the second member includes a cap having a threaded recess and further includes a threaded rod adapted to engage the threaded recess so as to move the second member relative to the first member and the threaded rod is made of a harder metal than the threaded recess; wherein the second member includes a tensile bar comprising two halves fitted into slotted openings; wherein each half includes a rib section fitted into a recess in a sleeve and a curved section defining a breaking point located at a center point between the two halves; wherein the tensile bar is configured to break at the breaking point when a predetermined force is applied. 2. The assembly tool of claim 1, wherein the threaded recess of the cap is made of a Nitinol and the threaded rod is made of a stainless steel. 3. The assembly tool of claim 2, wherein the threaded recess of the cap is made of Nitronic 60 and the threaded rod is made of 455 custom stainless steel. 4. The assembly tool of claim 1, wherein the predetermined force is between about 20001 bf and about 2500 lbf. 5. The assembly tool of claim 1, wherein the second member includes a housing adapted to house the tensile bar. 6. The assembly tool of claim 5, wherein the housing of the second member includes an upper restraint pivotally attached to the lower restraint. 7. The assembly tool of claim 6, wherein the upper restraint includes a t-shaped slot having an opening adapted to receive the tensile bar. 8. The assembly tool of claim 7, wherein the lower restraint includes a t-shaped slot having an opening perpendicular to the opening of the t-shaped slot of the upper restraint. 9. An assembly tool for assembly of a first component of a prosthesis to a second component of the prosthesis for use in joint arthroplasty, the tool comprising: a first member operably associated with the first component, the first member defining a first member longitudinal axis thereof; a second member operably associated with the second component, the second member including a tensile bar comprising two halves fitted into slotted openings; wherein each half includes a rib section fitted into a recess in a sleeve and a curved section defining a breaking point located at a center point between the two halves; wherein the tensile bar is configured to break at the breaking point when a predetermined force is applied; wherein the second member includes a housing configured to retain the tensile bar after the tensile bar breaks. 10. The assembly tool of claim 9, wherein the predetermined force is between about 2000 lbf and about 25001 bf. 11. The assembly tool of claim 9, wherein the housing of the second member includes an upper restraint pivotally attached to the lower restraint. 12. The assembly tool of claim 11, wherein the upper restraint includes a t-shaped slot having an opening adapted to receive the tensile bar. 13. The assembly tool of claim 11, wherein the lower restraint includes a t-shaped slot having an opening perpendicular to the opening of the t-shaped slot of the upper restraint. 14. The assembly tool of claim 11, wherein the lower restraint includes a spring- loaded lower section adapted to contain the tensile bar in the lower restraint. 15. The assembly tool of claim 9, wherein the second member includes a cap having a threaded recess and further includes a threaded rod adapted to engage the threaded recess so as to move the second member relative to the first member and the threaded rod is made of a harder metal than the threaded recess. 16. The assembly tool of claim 15, wherein the threaded recess of the cap is made of a Nitinol and the threaded rod is made of a stainless steel. 17. The assembly tool of claim 16, wherein the threaded recess of the cap is made of Nitronic 60 and the threaded rod is made of 455 custom stainless steel.
