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 patient-specific surgical instrumentation system for use in surgery on a hip joint of a patient, comprising:
a block having a patient-specific surface and a guide;
wherein the patient-specific surface has at least a portion that is substantially a negative of a corresponding portion of a surface of a proximal femur of the patient; and
wherein the guide is configured relative to the patient-specific surface to define a guide path oriented at a predetermined angle relative to a femoral neck or shaft axis of the femur when the patient-specific surface is placed against and aligned with the corresponding portion of the surface of the femur.
2. A patient-specific surgical instrumentation system for use in surgery on a hip joint of a patient, comprising:
a block having an alignment surface and a guide;
wherein the alignment surface has at least a portion that is substantially a negative of a corresponding portion of a femoral neck surface of the patient; and
wherein the guide is configured relative to the patient-specific surface to define a predetermined path relative to at least one of an anatomical or biomechanical axis of the femur when the patient-specific surface is placed against and aligned with the corresponding portion of the surface of the femur.
3. A patient-specific surgical instrumentation system for use in surgery on a hip joint of a patient, comprising:
a block having a contact surface and a guide;
wherein the contact surface has at least a portion that is derived from image data of a corresponding surface portion of a patient's femur; and
wherein the guide is configured relative to the contact surface to define a guide path in a predetermined position relative to a femoral neck axis of the femur when the contact surface is placed against and aligned with the corresponding surface portion of the patient's femur.
4. A patient-specific surgical instrumentation system for use in surgery on a hip joint of a patient, comprising:
a jig having a patient-specific surface and a guide aperture;
wherein the patient-specific surface has at least a portion that is based at least in part on image data of a corresponding portion of a surface of at least one of a femoral head and neck of a femur of the patient; and
wherein the guide aperture is configured relative to the patient-specific surface to define a guide path along an axis extending through at least a portion of the femoral neck or head of the patient when the patient-specific surface is placed against and aligned with the corresponding portion of the surface of the femur.
5. A patient-specific surgical instrumentation system for use in surgery on a hip joint of a patient, comprising:
a block having a contact surface and a guide;
wherein the contact surface has at least a portion that is based on image data of a corresponding portion of a surface of a at least one of a femoral head or neck of the patient; and
wherein the guide is configured relative to the patient-specific surface to define a predetermined guide path relative to a femoral neck or shaft axis of the femur when the patient-specific surface is placed against and aligned with the corresponding portion of the surface of the femur.
6. The instrumentation system of claim 1 , further comprising a femoral implant for the hip joint of the patient.
7. The instrumentation system of claim 1 , further comprising one or more surgical tools for surgery on an acetabulum of the hip joint of the patient.
8. The instrumentation system of claim 7 , further comprising an acetabular implant for the hip joint of the patient.
9. The instrumentation system of claim 2 , further comprising a femoral implant for the hip joint of the patient.
10. The instrumentation system of claim 2 , further comprising one or more surgical tools for surgery on an acetabulum of the hip joint of the patient.
11. The instrumentation system of claim 10 , further comprising an acetabular implant for the hip joint of the patient.
12. The instrumentation system of claim 3 , further comprising a femoral implant for the hip joint of the patient.
13. The instrumentation system of claim 3 , further comprising one or more surgical tools for surgery on an acetabulum of the hip joint of the patient.
14. The instrumentation system of claim 13 , further comprising an acetabular implant for the hip joint of the patient.
15. The instrumentation system of claim 4 , further comprising a femoral implant for the hip joint of the patient.
16. The instrumentation system of claim 4 , further comprising one or more surgical tools for surgery on an acetabulum of the hip joint of the patient.
17. The instrumentation system of claim 16 , further comprising an acetabular implant for the hip joint of the patient.
18. The instrumentation system of claim 5 , further comprising a femoral implant for the hip joint of the patient.
19. The instrumentation system of claim 5 , further comprising one or more surgical tools for surgery on an acetabulum of the hip joint of the patient.
20. The instrumentation system of claim 19 , further comprising an acetabular implant for the hip joint of the patient.
