Claims30
A patient-specific surgical system for surgery of joint of a patient, the system comprising:
- a patient-specific surface for engaging a substantially uncut joint surface, the surface conforming to and being substantially a negative of the uncut joint surface;
- and
- a surgical instrument guide for directing a surgical instrument, wherein the surgical instrument guide has a predetermined position relative to the conforming surface and is fixed at a predetermined orientation from an axis associated with said joint selected from the group consisting of an anatomical axis, a biomechanical axis, and a combination thereof;
- wherein the surgical instrument guide defines a path through at least a portion of the joint, the path having a position based on a predetermined rotation of an articular implant, the surgical instrument guide configured to guide the surgical instrument along the path, wherein said joint is an ankle joint of the patient.
A patient-specific surgical system for surgery of a joint of a patient, the system comprising:
- a patient-specific surface for engaging a substantially uncut joint surface, the surface conforming to and being substantially a negative of the uncut joint surface;
- and
- a surgical instrument guide for directing a surgical instrument, wherein the surgical instrument guide has a predetermined position relative to the conforming surface and is fixed at a predetermined orientation from an axis associated with said joint selected from the group consisting of an anatomical axis, a biomechanical axis, and a combination thereof;
- wherein the surgical instrument guide defines a path through at least a portion of the joint, the path having a position based on at least one of a predetermined axial rotation angle of an orthopedic implant, and wherein the surgical instrument guide is configured to guide the surgical instrument along the path, wherein said joint is an ankle joint of the patient.
A patient-specific surgical system for surgery of a joint of a patient, the system comprising:
- a patient-specific surface for engaging a substantially uncut joint surface, the surface conforming to and being substantially a negative of the uncut joint surface;
- and
- a cutting guide for directing a surgical cutting instrument, wherein the guide has a predetermined position relative to the conforming surface and is fixed at a predetermined orientation from an axis associated with said joint selected from the group consisting of an anatomical axis, a biomechanical axis, and a combination thereof;
- wherein the cutting guide defines a cutting path through at least a portion of the joint, the path having a position based on at least one of a predetermined axial rotation angle of an orthopedic implant, wherein said joint is an ankle joint of the patient.
A patient-specific surgical system for surgery of a joint of a patient, the system comprising:
- a patient-specific surface for engaging a substantially uncut joint surface, the surface conforming to and being substantially a negative of the uncut joint surface;
- and
- a hole for directing a surgical cutting instrument, wherein the hole has a predetermined position relative to the conforming surface and is fixed at a predetermined orientation from an axis associated with said joint selected from the group consisting of an anatomical axis a biomechanical axis, and a combination thereof;
- wherein the hole defines a path through at least a portion of the joint, the path having a position based on at least one of a predetermined axial rotation angle of an orthopedic ankle implant.
