Abstract
Disclosed is a method and apparatus for performing a procedure relative to a selected portion of the anatomy, for example, preparing a portion of a joint, such as a knee, for implantation of a prosthesis. The manner of preparing the selected portion of the anatomy can be assisted with the various apparatuses disclosed.
Claims28
A system for performing a resection of a selected portion of an anatomy with a resection instrument, the system comprising:
- a first member fixable to the selected portion of the anatomy;
- a first movement defining portion defined by said first member;
- a second member defining a second movement portion;
- wherein said first movement portion defined by said first member and said second movement portion defined by said second member is operable to allow said second member to be moveable relative to said first member from a first position to a second position;
- wherein the resection instrument is positionable relative to said second member in the first position and the second position to form a selected resection of the selected portion of the anatomy.
A system for resecting a distal femoral portion with a resection instrument, the system comprising:
- a main guide portion;
- a first dynamic connection portion operably interconnected with the main guide portion;
- a first dynamic guide member;
- a second dynamic connection portion operably interconnected with the first dynamic guide member;
- a guide surface defined by at least one of the main guide portion, the first dynamic guide member, or combinations thereof;
- wherein the guide surface is operable to guide the resection instrument during a substantial portion of the distal femoral resection.
The system of claim 18, wherein the guide surface includes a first guide surface defined by said main guide portion to form an anterior chamfer cut on the femur, a second guide surface defined by said main guide portion to form a posterior chamfer cut on the femur, a third guide surface defined by said first dynamic guide member to form an anterior resection, and a fourth guide surface defined by said second dynamic guide member to guide a resection instrument to form a posterior resection.
A method of using a resection assembly comprising:
- providing a first member and a second member;
- fixing the first member to a portion of the anatomy with a first fixation member;
- guiding a first resection of a portion of the anatomy with the first member;
- moving a second member relative to the first member;
- and
- guiding a second resection of a portion of the anatomy with the second member while moving the second member.
A method of using a resection assembly, comprising:
- providing a first member and a second member;
- fixing the first member to a portion of the anatomy with a first fixation member;
- moving a second member relative to the first member;
- and
- guiding a second resection of the portion of the anatomy with the second member while moving the second member.
