Wrench for an implant

A wrench assembly for restraining a multicomponent hip implant while applying a torque to a fastener connecting the multiple components together, the hip implant including a distal stem component and a proximal body component, the proximal body component having a tapered neck portion, the assembly comprising:

• a handle;
• a socket shaft depending from the handle in torque transmitting relation, the socket shaft and handle being approximately perpendicular to one another;
• a socket coupled to the socket shaft in torque transmitting relation, the socket having a portion for engaging the neck taper portion of the implant in torque transmitting relation, the socket further having a through hole aligned with the fastener;
• and
• a driving shaft passing through the through hole in the socket and engaging the fastener such that with the handle torsionaly fixed, the implant is torsionaly fixed by way of the handle, socket shaft, socket and implant connections, and the driving shaft is movable relative to the socket to impart an opposing torque on the fastener.

A method for restraining an implant while applying a torque to the implant, the method comprising the steps of:

• providing a wrench assembly comprising a handle, a socket shaft depending from the handle in torque transmitting relation, a socket coupled to the socket shaft in torque transmitting relation, the socket having an implant engaging portion for engaging the implant in torque transmitting relation, the socket further having a through hole;
• engaging the socket with the implant;
• inserting the driving shaft through the through hole;
• engaging the driving shaft with a portion of the implant;
• and
• applying opposing torque to the handle and driving shaft.
