Method and apparatus for resecting bone
First Claim
1. A surgical instrument for resecting a bone with a saw, the saw including a blade, said surgical instrument comprising:
- a guide body operable to be used during resection of the bone; and
a laterally extending member defined by a first component operably attached to said guide body at a first attachment area and a second component operably attached to said guide body at a second attachment area, said attachment areas defining two opposing walls, said components being spaced apart such that a constrained opening is defined therebetween for capturing the blade, said constrained opening extending substantially between said attachment areas.

Abstract
A method and apparatus for resecting bone includes an anterior femur resection guide assembly for performing an anterior femur osteotomy, a distal femur resecting guide assembly for performing a distal femur osteotomy, a compound posterior femur-chamfer resection guide assembly for performing an anterior femur osteotomy, and a tibia resection guide assembly for performing a proximal tibia osteotomy. The anterior femur resection guide assembly, the distal femur resecting guide assembly, the tibia resecting guide assembly, and the compound posterior femur-chamfer resection guide assembly each includes a capture plate subassembly which restricts lateral movement of a saw during resection. The distal femur resecting guide assembly and the tibia resecting guide assembly also include subassemblies for verifying the correct positioning of a distal femur and proximal tibia osteotomies.

10. A method for resecting a bone with a saw, the saw including a blade and the bone having a long axis, said method comprising the steps of:
-
providing a surgical instrument for resecting the bone, said surgical instrument having a guide body and a laterally extending member operably attached to said guide body, said laterally extending member defined by a first component operably attached to said guide body at a first attachment area and a second component operably attached to said guide body at a second attachment area, said attachment areas defining two opposing walls, said components being spaced apart such that a constrained opening is defined therebetween for capturing the blade, said constrained opening extending substantially between said attachment areas, said surgical instrument further including an alignment member attached to said guide body for aligning said surgical instrument with respect to the long axis of the bone, said laterally extending member including a constrained opening through which the blade is able to pass; positioning said guide body into axial alignment with the long axis of the bone by observing the relative position of said alignment member; moving said laterally extending member from a first position in which said laterally extending member is spaced apart from the bone to a second position in which at least a portion of said laterally extending member is located adjacent to the bone; inserting the blade through said constrained opening formed between said attachment areas; and resecting the bone by movement of the blade of the saw. - View Dependent Claims (11)
