Surgical instrumentation and methods of use for implanting a prosthesis
View Patent ↗In one embodiment, the present invention includes a method of alignment for resection of tissue including obtaining a surgical device comprising an alignment guide, a first guide structure and a second guide structure; securing the alignment guide to a bone, the alignment guide including a positioning block; placing the first guide structure onto the positioning block of the alignment guide; viewing a target location of a first resection plane on the bone using the first guide structure; adjusting the target location of the first resection plane by adjusting a position of the first guide structure; attaching the second guide structure to the first guide structure; viewing a target location of a second resection plane on the bone using the second guide structure; and adjusting the target location of the second resection plane by adjusting a position of the second guide structure.
1. A method of resecting bone comprising:
aligning a surgical device having first and second resection planes, wherein the first resection plane is approximately perpendicular to a longitudinal axis of a first bone and the second resection plane is transverse to the first resection plane;
resecting the first bone by cutting along each of the first and second resection planes;
resecting a second bone by cutting along a third resection plane of the surgical device to create a first surface,
positioning a first guide at least partially on the first surface of the second bone;
resecting the second bone using a first resection tool advanced over a guide surface of the first guide to create a second surface of the second bone defined at an angle relative to the first surface of the second bone and abutting the first surface; and
resecting the second bone using a second resection tool placed through a second guide to create a third surface of the second bone defined at an angle relative to the first surface of the second bone and separated from the second surface of the second bone by the first surface,
wherein the first guide and the second guide are separate parts that are attached to one another after the positioning step.
2. The method of claim 1 , wherein a pin is placed through one of a first and second ends of an opening in the surgical device defined at least partially by the first or third resection plane to prevent resection beyond a location of the pin within the opening.
3. The method of claim 1 , wherein the first resection plane is parallel to the third resection plane.
4. The method of claim 3 , wherein the second resection plane is at an obtuse angle relative to the first resection plane when measured from a cutting side of the first and second resection planes.
5. The method of claim 1 , further comprising stabilizing the surgical device relative to the first bone by placing a fastener through an aperture located in the surgical device adjacent to the first resection plane and into engagement with the first bone.
6. The method of claim 5 , further comprising stabilizing the surgical device relative to the second bone by placing a fastener through a second aperture located in the surgical device adjacent to the third resection plane and into engagement with the second bone.
7. The method of claim 1 , further comprising removing the surgical device prior to positioning the first guide and inserting a space evaluator between the first resection plane on the first bone and the third resection plane on the second bone to determine an amount of tissue that has been removed.
8. A method of resecting a bone for a joint repair comprising:
positioning a first guide at least partially on a first surface of the bone, the first surface being a previously prepared planar resection surface;
resecting the bone using a first resection tool advanced over a guide surface of the first guide to create a second surface of the bone defined at an angle relative to the first surface of the bone and abutting the first surface; and
resecting the bone using a second resection tool placed through a second guide to create a third surface of the bone defined at an angle relative to the first surface of the bone and separated from the second surface of the bone by the first surface,
wherein the first guide and the second guide are separate parts that are attached to one another after the positioning step.
9. The method according to claim 8 , wherein positioning the first guide includes inserting a pin through an aperture in the first guide to secure the first guide to the bone, the pin extending through the aperture of the first guide when positioned.
10. The method according to claim 9 , wherein the pin is oriented such that an axis through the pin is at an angle of 45 degrees or less relative to a plane through the second surface of the bone.
11. The method of claim 8 , wherein the first resection tool is oriented in parallel to the guide surface of the first guide when resecting the bone so that the created second surface and the guide surface are parallel to one another.
12. The method of claim 11 , wherein resecting the bone using the first resection tool involves oscillating the first resection tool in parallel to the guide surface of the first guide.
13. The method of claim 8 , wherein the second resection tool is oriented orthogonally to the third surface of the bone when resecting the bone.
14. The method of claim 13 , wherein resecting the bone using the second resection tool involves translating the second resection tool along an axis between two locations in a channel within a body of the second guide.
