Abstract
A guide for use in cutting a bone is disclosed. The guide includes a bone contacting surface contoured to conformably mate with a first bone surface when placed against the first bone surface, and a guide surface that is spaced apart from the bone contacting surface. At least one prescribed patient-specific depth of cut information is provided on the guide surface that corresponds to the desired depth of cut being made using the guide.
Claims35
A guide for use in cutting a bone, the bone having a first bone surface and a second bone surface, wherein a varying bone depth is defined between the first bone surface and the second bone surface, the guide comprising:
- a bone contacting surface comprising a contour that is complementary to a contour of the first bone surface such that the bone contacting surface conformably mates with the first bone surface when placed against the first bone surface;
- a guide surface spaced apart from the bone contacting surface and provided thereon with at least one prescribed patient-specific depth of cut information in correspondence with the varying bone depth;
- and
- at least one aperture extending through the guide from the guide surface,
- wherein when the guide is placed on the bone against the first bone surface, the at least one aperture extends through the guide from the guide surface towards the second bone surface,
- wherein the aperture is configured to receive and guide a cutting tool for cutting the bone.
A kit for use in removing a portion of a bone, the bone having a first bone surface and a second bone surface, wherein a varying bone depth is defined between the first bone surface and the second bone surface, the kit comprising:
- a guide comprising:
- a bone contacting surface comprising a contour that is complementary to a contour of the first bone surface such that the bone contacting surface conformably mates with the first bone surface when placed against the first bone surface;
- a guide surface spaced apart from the bone contacting surface and provided thereon with at least one prescribed patient-specific depth of cut information in correspondence with the varying bone depth;
- and
- at least one aperture extending through the guide from the guide surface, wherein the aperture is configured to receive and guide a cutting tool for cutting the bone;
- and
- a cutting tool comprising:
- an elongated body having a first end and a second end;
- a cutting tip provided at the first end.
A method for cutting a bone, the bone having a first bone surface and a second bone surface on opposite side of the first bone surface, wherein a varying bone depth is defined between the first bone surface and the second bone surface, the method comprising:
- (a) placing a guide against the first bone surface, wherein the guide comprises:
- a bone contacting surface comprising a contour that is complementary to a contour of the first bone surface such that the bone contacting surface conformably mates with the first bone surface when placed against the first bone surface;
- a guide surface spaced apart from the bone contacting surface and provided thereon with at least one prescribed patient-specific depth of cut information in correspondence with the varying bone depth;
- and
- at least one aperture extending through the guide from the guide surface, wherein when the guide is placed on the bone against the first bone surface, the at least one aperture extends through the guide from the guide surface towards the second bone surface, wherein the aperture is configured to receive and guide a cutting tool for cutting the bone;
- and
- (b) inserting a cutting tool having an elongated body through the at least one aperture at a first location;
- and
- (c) cutting into the bone from the first bone surface toward the second bone surface to a depth that is indicated by the prescribed patient-specific depth of cut information corresponding to the first location.
