Abstract
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.
Claims176
A surgical instrument for use in surgically replacing or resurfacing portions of or an entire hip joint of a patient, comprising:
- a block 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 is substantially a negative of a subchondral bone surface of a hip joint;
- and
- wherein the guide has a position or orientation relative to the patient-specific surface to define a predetermined 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 subchondral bone surface.
A surgical instrument for use in surgically replacing or resurfacing portions of or an entire hip joint of a patient, comprising:
- a block 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 is substantially a negative of a subchondral bone surface of a hip joint;
- wherein the guide has a position or orientation relative to the patient-specific surface to define a predetermined 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 subchondral bone surface;
- and
- wherein the path for the surgical tool is configured to provide a predefined anteversion or retroversion of at least one acetabular or femoral implant when the patient specific surface is placed against and aligned with the surface.
A surgical instrument for use in surgically replacing or resurfacing portions of or an entire hip joint of a patient, comprising:
- a block having a patient-specific surface and a guide to direct or accommodate a surgical tool;

A surgical instrument for use in surgically replacing or resurfacing portions of or an entire hip joint of a patient, comprising:
- a block 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 is substantially a negative of a cartilage surface of a hip joint;
- and
- wherein the guide has a position or orientation relative to the patient-specific surface to define a predetermined 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 cartilage surface.
