Patient selectable joint arthroplasty devices and surgical tools
View Patent ↗Disclosed herein are methods, compositions and tools for repairing articular surfaces repair materials and for repairing an articular surface. The articular surface repairs are customizable or highly selectable by patient and geared toward providing optimal fit and function. The surgical tools are designed to be customizable or highly selectable by patient to increase the speed, accuracy and simplicity of performing total or partial arthroplasty.
1. A joint arthroplasty system for repairing a joint of a patient, the system comprising:
a surgical instrument kit comprising:
a first template, the first template including: (i) a first contact surface substantially conforming to and for engaging a first joint surface of the joint of patient; and (ii) a first guide for directing movement of a surgical instrument;
a second template, the second template including: (i) a second contact surface substantially conforming to and for engaging a second joint surface of the joint of the patient; and (ii) a second guide for directing movement of a surgical instrument; and
a linkage for cross-referencing a first cut created by the first template and a second cut created by the second template; and
one or more implant components for the joint of the patient.
2. The system of claim 1 , wherein the one or more implant components are selected for the patient from pre-existing implant components.
3. The system of claim 2 , wherein the selected one or more implant components are further shaped based on the image data of the joint of the patient.
4. The system of claim 1 , wherein the one or more implant components designed for the patient using the image data of the joint of the patient.
5. The system of claim 1 , wherein the joint of the patient is a knee joint, a shoulder joint, an ankle joint, a hip joint, or a wrist joint of the patient.
6. The system of claim 1 , wherein the first cut comprises a bone cut.
7. The system of claim 1 , wherein the first cut comprises a drilled hole.
8. The system of claim 1 , wherein the first contact surface and the second contact surface are on the same articular side of the joint.
9. The system of claim 1 , wherein the first contact surface and the second contact surface are on opposing articular sides of the joint.
10. The system of claim 1 , wherein the linkage comprises a member of the following group: a spacer, a hinge or a rachet-like device.
11. The system of claim 1 , wherein the linkage is configured to indirectly cross-reference the first cut and the second cut.
12. A method of joint arthroplasty for repairing a hip, shoulder or ankle joint of a patient, the method comprising:
(a) positioning at least one contact surface of a first template onto a first joint surface, the first template substantially conforming to said first joint surface;
(b) cross-referencing a second template to the first template to align position of the second template on a second joint surface, the second joint surface opposing the first joint surface, the second template including at least one guide; and
(c) directing movement of a surgical instrument using the at least one guide.
13. The method according to claim 12 , wherein the cross-referencing is performed using a member of the following group: a spacer, a hinge or a rachet-like device.
14. The method according to claim 13 , wherein the spacer, hinge or rachet-like device is used for ligament balancing.
15. The method according to claim 12 , wherein the cross-referencing step includes indirectly cross-referencing the second template to the first template.
