SURGICAL INSTRUMENT FOR PREPARING PATIENT'S TIBIA TO RECEIVE IMPLANT

摘要

PROBLEM TO BE SOLVED: To provide an orthopaedic surgical instrument system.;SOLUTION: The orthopaedic surgical instrument system includes: an orthopaedic surgical instrument adapted to be positioned on a proximal end of a patient's tibia; a tibial bearing trial assembly; a tibial evaluation component; and a tibial base trial component configured to be coupled to the orthopaedic surgical instrument. The tibial evaluation component includes a base plate and a generally Y-shaped posterior buttress extending upwardly from the superior surface of the base plate, such that the posterior buttress of an insert component is configured to be received in the opening of the tibial bearing trial assembly to prevent the rotation of the tibial bearing trial component relative to the tibial base trial component.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2017,JPO&INPIT
