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 surgical tool for use in surgery on a hip joint of a patient, comprising:
a body having a patient-specific surface and a guide to direct or accommodate a surgical instrument;
wherein at least a portion of the patient-specific surface has a shape that substantially matches a shape of a corresponding acetabular surface of the hip joint, wherein the corresponding acetabular surface of the hip joint includes a corresponding surface portion selected from the group consisting of an acetabular fossa, an acetabular wall, an acetabular rim, a tri-radiate cartilage surface, and any combination thereof, of the hip joint;
wherein the guide is configured relative to the patient-specific surface to provide a predefined path for the surgical instrument that is aligned through a portion of tissue associated with the hip joint when the patient-specific surface is placed against and aligned with the corresponding acetabular surface; and wherein the predefined path for the surgical instrument is configured to provide a predefined orientation of an acetabular implant when the patient-specific surface is placed against and aligned with the corresponding acetabular surface,
wherein the shape of the corresponding acetabular surface of the hip joint and the predefined orientation of the acetabular implant are derived from the electronic image data of the hip joint.
2. The surgical tool of claim 1 , wherein the predefined orientation includes a predefined anteversion or retroversion of the acetabular implant when the patient-specific surface is placed against and aligned with the acetabular surface.
3. The surgical tool of claim 1 , wherein the predefined orientation includes a predefined rotation of the acetabular implant when the patient-specific surface is placed against and aligned with the acetabular surface.
4. The surgical tool of claim 1 , wherein the predefined orientation includes in a predefined tilt of the acetabular implant when the patient-specific surface is placed against and aligned with the acetabular surface.
5. A system comprising the surgical tool of claim 1 and one or more implant components.
6. The system of claim 5 , wherein the one or more implant components includes the acetabular implant.
7. The system of claim 5 , wherein the one or more implant components includes a femoral implant.
8. The system of claim 5 further includes one or more surgical tools.
9. The system of claim 8 , wherein the one or more surgical tools include at least one reusable surgical tool.
10. The system of claim 8 , wherein the one or more surgical tools include at least one surgical tool that is patient-specific and for single use.
11. The surgical tool of claim 1 , wherein the surgical instrument is a surgical reamer, a surgical drill, or a surgical saw.
12. A surgical tool for use in surgery on a hip joint of a patient, comprising:
a body having a patient-specific surface and a guide to direct or accommodate a surgical instrument;
wherein at least a portion of the patient-specific surface has a shape that substantially matches a shape of a corresponding acetabular rim surface of the hip joint;
wherein the guide is configured relative to the patient-specific surface to provide a predefined path for the surgical instrument that is aligned through a portion of tissue associated with the hip joint when the patient-specific surface is placed against and aligned with the acetabular rim surface; and wherein the predefined path for the surgical instrument is configured to provide a predefined orientation of an acetabular implant when the patient-specific surface is placed against and aligned with the acetabular rim surface,
wherein the shape of the corresponding acetabular rim surface of the hip joint and the predefined orientation of the acetabular implant are derived from the electronic image data of the hip joint.
13. The surgical tool of claim 12 , wherein the predefined orientation includes a predefined anteversion or retroversion of the acetabular implant when the patient-specific surface is placed against and aligned with the acetabular rim surface.
14. The surgical tool of claim 12 , wherein the predefined orientation includes a predefined rotation of the acetabular implant when the patient-specific surface is placed against and aligned with the acetabular rim surface.
15. The surgical tool of claim 12 , wherein the predefined orientation includes in a predefined tilt of the acetabular implant when the patient-specific surface is placed against and aligned with the acetabular rim surface.
16. The surgical tool of claim 1 , wherein the corresponding acetabular surface of the hip joint includes one or more osteophytes.
17. The surgical tool of claim 12 , wherein the patient-specific surface has a portion substantially conforming to an acetabular wall surface of the hip joint.
18. The surgical tool of claim 12 , wherein the patient-specific surface has a portion substantially conforming to an acetabular fossa portion of the hip joint.
19. The surgical tool of claim 12 , wherein the patient-specific surface has a portion substantially conforming to a cartilage surface portion of the hip joint.
20. The surgical tool of claim 12 , wherein the patient-specific surface has a portion substantially conforming to one or more osteophytes of the hip joint.
