MODULAR INSTRUMENTATION FOR BONE PREPARATION AND IMPLANT TRIAL REDUCTION OF ORTHOPEDIC IMPLANTS

摘要

The invention provides a modular system of components used as bone preparati on tools and trial prosthesis components. The system includes a trial tibial tr ay bearing element that mounts upon a prepared tibia, a punch bushing that serves the purpose o f a trial tibial stem and helps to guide a tibial punch through the tibia. The trial template element, the punch bushing and the tibial punch can remain in position on the patient's tibia while one or more trial tibial bearing inserts or samples are attached thereto to determi ne the proper fit and orientation of a prosthesis.
