Abstract
A safety broach for use in arthroplasty for hip joints, and a system including the same. The system may further include a segmented or otherwise flexible reamer and an implant. The safety broach includes a hollow interior passage that serves to guide the reamer when the safety broach is in place in the bone. The system may include any number of sizes of safety broaches, segmented reamers, and implants. In any case, such a safety broach may be capable of assisting with arthroplasty for hip joints (or any other joint), while typically providing enhanced safety and reliability of the arthroplasty.

A joint replacement system comprising:
- a first bone preparation tool comprising:
- a first main body having two opposing ends and a hollow interior passage, wherein the main body also has a first opening at a first end and a second opening at a second end, the second opening opposing the first opening of the first main body;
- and
- a plurality of first cutting features formed on the exterior surface of the first main body;
- and
- a second bone preparation tool comprising:
- a second main body having a plurality of cutting features and a plurality of segments,
- wherein the hollow interior passage is configured for guiding the second bone preparation tool from the first end to the second end of the first main body, and
- wherein the hollow interior passage is configured to allow the second bone preparation tool to exit the second end of the first main body, and
- wherein the first bone preparation tool and the second bone preparation tool are configured to be used together.
A bone preparation tool comprising:
- a main body having two opposing ends and a hollow interior passage, wherein the main body also has a first opening at a first end and a second opening at a second end, the second end opposing the first end of the hollow interior passage;
- a stem portion formed on an exterior surface of the main body and being configured to facilitate manipulation of the main body;
- and
- a plurality of cutting features formed on the exterior surface of the main body,
- wherein the hollow interior passage is configured to guide a second bone preparation tool from the first end to the second end, and
- wherein the hollow interior passage is configured to allow the second bone preparation tool to exit the second end at the second opening,
