Assembly tool for modular implants, kit and associated method

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 second component including a stem defining a stem axis, the first component defining a bore for receiving the stem, the bore defining a bore axis, the assembly tool comprising:

• a first member defining (i) a longitudinal opening and (ii) a first member longitudinal axis that passes through said longitudinal opening, said first member being configured to engage the first component of the prosthesis with said first member longitudinal axis aligned with said bore axis;
• a second member defining a second member longitudinal axis and including:
• (i) a drive shaft rotatable about said second member longitudinal axis,
• (ii) a translating member translatably coupled to said drive shaft and configured to translate along said second member longitudinal axis in response to rotation of said drive shaft, and
• (iii) a rotatable member coupled to said translating member and configured to translate along said second member longitudinal axis with said translating member in response to rotation of said drive shaft, said rotatable member being manually rotatable with respect to said translating member about said second member longitudinal axis;
• wherein:
• at least said translating member of said second member is disposed in said longitudinal opening of said first member with said second member longitudinal axis aligned with said first member longitudinal axis;
• and
• said rotatable member is configured to be fixedly connected to the stem of the second component with said stem axis substantially aligned with said second member longitudinal axis.
