Patient Selectable Joint Arthroplasty Devices and Surgical Tools
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 tool;
wherein the patient-specific surface has at least a portion that substantially matches a corresponding femoral neck surface of the hip joint;
wherein the guide is configured relative to the patient-specific surface to provide a predefined path for the surgical tool 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 femoral neck surface; and
wherein the path for the surgical tool is configured to provide a predefined orientation of a femoral implant when the patient specific surface is placed against and aligned with the surface.
2 . The surgical instrument of claim 1 , wherein the orientation includes a predefined anteversion or retroversion of the femoral implant when the patient specific surface is placed against and aligned with the femoral neck surface.
3 . The surgical instrument of claim 1 , wherein the orientation includes a predefined rotation of the femoral implant when the patient specific surface is placed against and aligned with the femoral neck surface.
4 . 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 tool;
wherein the patient-specific surface has at least a portion that substantially matches a corresponding femoral head surface of the hip joint;
wherein the guide is configured relative to the patient-specific surface to provide a predefined path for the surgical tool 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 femoral head surface; and
wherein the path for the surgical tool is configured to provide a predefined orientation of a femoral implant when the patient specific surface is placed against and aligned with the surface.
5 . The surgical instrument of claim 1 , wherein the orientation includes a predefined anteversion or retroversion of the femoral implant when the patient specific surface is placed against and aligned with the femoral head surface.
6 . The surgical instrument of claim 1 , wherein the orientation includes a predefined rotation of the femoral implant when the patient specific surface is placed against and aligned with the femoral head surface.
