Abstract
An orthopaedic surgical instrument includes a cutting block having a bone-engaging surface and an outer surface positioned opposite the bone-engaging surface, a first cutting guide slot defined in the cutting block, and a second cutting guide slot defined in the cutting block. The orthopaedic surgical instrument includes two mounting systems configured to separately secure the cutting block to a bone of a patient.
Claims22
An orthopaedic surgical instrument comprising:
- a cutting block having a bone-engaging surface and an outer surface positioned opposite the bone-engaging surface,
- a first cutting guide slot defined in the cutting block, the first cutting guide slot defining a first imaginary plane,
- a second cutting guide slot defined in the cutting block, the second cutting guide slot defining a second imaginary plane that extends oblique to the first imaginary plane,
- a first mounting system configured to secure the cutting block to a bone of a patient, the first mounting system including (i) a plate removably coupled to the cutting block, and (ii) a pair of spikes attached to the plate, each spike having a bone-engaging tip, and
- a second mounting system configured to secure the cutting block to the bone of the patient, the second mounting system including (i) a plurality of guide bores extending through the bone-engaging surface and the outer surface of the cutting block, and (ii) a plurality of fixation pins configured to be received in the plurality of guide bores, each fixation pin having a bone-engaging tip.

An orthopaedic surgical instrument comprising:
- a cutting block including a bone-engaging surface having an aperture defined therein,
- a first bracket positioned in the aperture defined in the cutting block, and
- a second bracket configured to be positioned in the aperture of the cutting block in place of the first bracket, the second bracket having a pair of spikes extending outwardly therefrom, each spike having a bone-engaging tip,
- wherein (i) the first bracket and the cutting block cooperate to define a cutting guide slot, and (ii) the second bracket and the cutting block cooperate to define the cutting guide slot when the second bracket is positioned in the aperture of the cutting block.

An orthopaedic surgical instrument comprising:
- a cutting block,
- an anterior cutting guide slot defined in the cutting block,
- an anterior chamfer cutting guide slot defined in the cutting block,
- a first mounting system configured to secure the cutting block to a bone of a patient, the first mounting system including (i) a plate removably coupled to the cutting block, and (ii) a pair of spikes attached to the plate, each spike having a bone-engaging tip, and
- a second mounting system configured to secure the cutting block to the bone of the patient when the plate is detached from the cutting block, the second mounting system including (i) a plurality of guide bores extending through the cutting block, and (ii) a plurality of fixation pins configured to be received in the plurality of guide bores, each fixation pin having a bone-engaging tip.
