Abstract
A method of implant a knee prosthesis includes forming a bone void at an end of a bone, implanting a void filler in the bone void, and implanting a knee prosthesis onto the end of the bone so that a stem of the knee prosthesis is received by the void filler.
Claims3
A device for implantation into a bone void comprising:
- a sidewall defining a cavity for receipt of a portion of a joint prosthesis;
- and
- a selectively removable portion formed in the sidewall,
- wherein removal of the selectively removable portion forms a gap in the sidewall.
1 more element
A surgical system for forming a void in a bone comprising:
- a support member configured to be securely positioned within an intramedullary canal of the bone;
- an offset guide member having a longitudinal axis, the offset guide member being configured to attach to the support member so that the longitudinal axis of the offset guide member is in a fixed and offset relation with the intramedullary canal of the bone;
- and
- a cutting member for forming an offset bone void having a cutting head attached, the cutting member being configured to slidably engage the offset guide member along the longitudinal axis of the offset guide member.
1 more element
A surgical method for forming a void in bone comprising the steps of:
- positioning a support member securely within an intramedullary canal of a bone;
- attaching a guide member having a longitudinal axis to the support member in a fixed and offset relation to the intramedullary canal;
- connecting a cutting member having a cutting head to the guide member in a slidable arrangement along the longitudinal axis of the guide member such that the cutting head faces a first bone segment;
- and
- cutting the first bone segment along the longitudinal axis of the guide member, thereby forming a first offset bone void.
