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 system including a patient-specific surgical tool for use in surgery on a hip joint of a patient, the patient-specific surgical tool comprising:
a jig having a patient-specific surface and a guide;
the patient-specific surface being substantially a negative of a corresponding surface portion of the hip joint that includes an osteophyte, wherein the patient-specific surface has a portion having a shape that matches at least a portion of the osteophyte;
the guide providing a path having a position and orientation relative to the patient-specific surface to provide a predetermined path for a cutting or drilling or reaming or burring tool that is aligned through a portion of tissue of the hip joint.
2. The system of claim 1 , further comprising one or more hip implant components.
3. The system of claim 2 , wherein the one or more hip implant components includes an acetabular component.
4. The system of claim 2 , wherein the one or more hip implant components includes a femoral component.
5. A system including a surgical tool for use in surgically repairing a hip joint of a patient, the surgical tool comprising:
a cutting block having a patient-specific surface and a guide;
the patient-specific surface having a first portion that is substantially a negative of at least a portion of a surface adjacent an acetabulum including an osteophyte, wherein the patient-specific surface has a portion having a shape that matches at least a portion of the osteophyte;
the guide being shaped to accommodate a surgical tool for cutting or drilling and having a position and orientation relative to the patient-specific surface to provide a predetermined cutting path for the cutting tool that is aligned through a portion of bone of the hip joint.
6. The system of claim 5 , further comprising one or more hip implant components.
7. The system of claim 6 , wherein the one or more hip implant components includes an acetabular component.
8. The system of claim 6 , wherein the one or more hip implant components includes a femoral component.
9. A system including a surgical tool for use in surgically repairing a hip joint of a patient, the surgical tool comprising:
a block having a patient-specific surface and a guide aperture;
the patient-specific surface having a first portion that is substantially a negative of at least a portion of a surface of a femoral neck including an osteophyte, wherein the patient-specific surface has a portion having a shape that matches at least a portion of the osteophyte;
the guide aperture being sized to accommodate a surgical tool for cutting or drilling and have a position and orientation relative to the patient-specific surface to provide a predetermined cutting or drilling path for the surgical tool that is aligned through a portion of bone of the hip joint.
10. The system of claim 9 , further comprising one or more hip implant components.
11. The system of claim 10 , wherein the one or more hip implant components includes an acetabular component.
12. The system of claim 10 , wherein the one or more hip implant components includes a femoral component.
13. A system including a surgical tool for use in surgically repairing a hip joint of a patient, the surgical tool comprising:
a block having a patient-specific surface and a guide;
the patient-specific surface having a first portion that is substantially a negative of at least a portion of a junction between a femoral head and a femoral neck including an osteophyte, wherein the patient-specific surface has a portion having a shape that matches at least a portion of the osteophyte;
the guide aperture being sized to accommodate a surgical tool for cutting or drilling and have a position and orientation relative to the patient-specific surface to provide a predetermined cutting or drilling path for the surgical tool that is aligned through a portion of bone of the hip joint.
14. The system of claim 13 , further comprising one or more hip implant components.
15. The system of claim 14 , wherein the one or more hip implant components includes an acetabular component.
16. The system of claim 14 , wherein the one or more hip implant components includes a femoral component.
17. A system including a surgical tool for use in surgically repairing a hip joint of a patient, the surgical tool comprising:
a block having a patient-specific surface and a guide aperture;
the patient-specific surface having a first portion that is substantially a negative of at least a portion of surface of a femoral head including an osteophyte, wherein the patient-specific surface has a portion having a shape that matches at least a portion of the osteophyte;
the guide aperture being sized to accommodate a surgical tool for cutting or drilling and have a position and orientation relative to the patient-specific surface to provide a predetermined cutting or drilling path for the surgical tool that is aligned through a portion of bone of the hip joint.
18. The system of claim 17 , further comprising one or more hip implant components.
19. The system of claim 18 , wherein the one or more hip implant components includes an acetabular component.
20. The system of claim 18 , wherein the one or more hip implant components includes a femoral component.
