Abstract
An orthopaedic surgical instrument system includes a tibial base trial and a tibial insert trial. An insert adaptor is sized to be positioned in an aperture defined in the tibial insert trial. The insert adaptor includes a base sized to be positioned over a post of the tibial base trial and a locking tab positioned in the base and configured to engage the post of the tibial base trial.
Claims3
A method of trialing an orthopaedic prosthetic assembly, the method comprising:
- aligning a tibial trial component with a tibial base trial positioned on a proximal end of a patient's tibia,
- advancing the tibial trial component posteriorly to move a post of the tibial base trial component into a posterior passageway defined in the tibial trial component,
- coupling the tibial trial component to the tibial base trial component such that the tibial trial component is permitted to rotate relative to the tibial base trial,
- aligning a pair of transverse bores defined in a femoral component with a bore defined in a spine of the tibial trial component,
- advancing an elongated pin through the transverse bores and the spine of the tibial trial component to couple the femoral component to the tibial trial component, and
- moving the patient's joint through a range of motion including extension and flexion to evaluate a configuration of the orthopaedic prosthetic assembly corresponding to the tibial base trial and the tibial trial component.
