摘要:
A system for preparing an ankle bone to receive an ankle prosthesis is provided. The system includes a patient specific cutting guide that has an anterior surface, a posterior surface, and at least one cutting feature extending through the guide from the anterior surface. The posterior surface comprising a first protrusion or other member that extends from a first end fixed to the posterior surface to a second end disposed away from the first end of the first protrusion. The posterior surface has a second protrusion or other member that extends from a first end fixed to the posterior surface to a second end disposed away from the first end of the second protrusion. The first and second protrusions are spaced apart and have a length such that when the patient specific cutting guide is coupled with first and second bone references, which can include bushings implantable in bones, a clearance gap is provided between the posterior surface and the ankle bone.
