A femoral reamer () can include a base material () and a coating () disposed on the base material. The coating can be harder than the base material and, as a result, the femoral reamer can wear more slowly than if the coating was absent. The coating can be a different color than the base material. When the coating is worn off, such wear can be easily observed from a visual inspection of the femoral reamer. The coating can have an initial thickness (i.e., a thickness prior to use) that is related to a tolerance on a size and/or a shape of a hole drilled by the femoral reamer. When the coating is worn off, the size and/or the shape of the hole drilled by the femoral reamer may be at or near an edge of a specified tolerance range. The femoral reamer can be part of a kit and a method.

A device () used during a medical procedure to engage a cross-section of a bone is disclosed herein. The device is selectively expandable to correspond to the cross-section of the bone. Once the device is properly sized, the device is used as a sizing tool to select the proper size of an implant or as a surgical guide for preparing the bone with a surgical instrument, for example.
