Modular tapered reamer for bone preparation and associated method

A kit for use in performing hip joint arthroplasty, said kit to be utilized to prepare a cavity in the femoral canal of a femur with the use of a driver and to assist in performing a trial reduction, said kit comprising:

• a hip femoral component trial;
• and
• a reamer for preparation of the cavity in the femoral canal, said reamer including a first portion for placement at least partially in the cavity of the femur and a second portion connectable to the driver, said first and second trials and the driver being removably attachable to said second portion of said reamer, so that the said reamer and the driver can be assembled to prepare the cavity and so that said reamer and one of said first and second trial can be assembled to form a hip femoral component trial assembly without the removal of said reamer from the cavity, wherein the first portion of the reamer includes flutes having cutting edges adapted to cut into the long bone, the first portion further including reliefs to provide a path for the removal of cut bone.

A reamer for preparing a cavity in the intramedullary canal of a long bone with the use of a driver and for cooperation with an implant trial to assist in performing a trial reduction, said reamer comprising:

• a first portion for preparation of the cavity in the canal, the first portion adapted for placement at least partially in the cavity of the long bone;
• and
• a second portion operably connected to the first portion, said second portion connectable to the driver to rotate said reamer, said reamer being removably attachable to the trial and to the driver.

A driver for use with a reamer to prepare a cavity in the intramedullary canal of a long bone, said driver including indicia thereon corresponding to at least one of a bony landmark on a patient and a portion of a trial or an implant.
