Abstract: A reamer shaft extension includes a shaft positioned between a first end having a first coupling and a second end having a second coupling. The first coupling of each reamer shaft extension is selectively couplable with the second coupling of another reamer shaft extension such that a select amount of reamer shaft extensions are assembled together to form a reamer shaft extension assembly for use in a reaming procedure. Each reamer shaft extension further has a sufficiently short enough length such that each reamer shaft extension is insertable within a sterilization tray for use in a sterilization procedure.

Abstract: In one embodiment, a Metal Injection Molded (MIM) body may have one or more surfaces comprising a zirconium alloy. A method of forming an oxide layer on the zirconium alloy surface(s) of the MIM body may include hot isostatic pressing the MIM body, heat treating the MIM body, machining the MIM body to desired shape dimensions, polishing the surface of the MIM body, and oxidizing the polished surface of the MIM body. In some embodiments, the polishing step may include a first vibratory finishing step; and a second vibratory finishing step.
