<p>A revision tool may include a revision rod, crank and osteotome. The osteotome may include a shearing portion and a shank, and may be coupled to the revision rod via advancing device threads. The revision rod may be driven into an implant and engage the implant using an implant pin and implant threads. The osteotome may then be driven by the crank and positioned by the shank to sheer bone surrounding the implant. A slap hammer may then be used to remove the implant attached to the revision rod.</p> |
