The primary purpose of a femoral broach is to prepare the femur for the insertion of a joint prosthesis, specifically in hip replacement surgeries. It is designed to create a precise cavity in the femoral bone by removing a specific amount of material, thereby allowing for a snug fit for the implant. In this context, the broach essentially "grates" or files the inside of the femur to ensure that the surface is appropriately shaped and sized for optimal implant stability.

This tool is crucial because proper preparation of the bone affects the overall success of the surgical procedure and subsequent healing. The broach must be able to create consistent and accurate dimensions to match the prosthetic device effectively. Therefore, while it is not merely filing, the action of shaping the bone is integral to the broaching process, and this aligns with the function described. This usage of the femoral broach emphasizes its role in achieving a well-fitted implant, directly impacting patient outcomes.
