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 instrument system for use in surgically replacing or resurfacing all or part of a 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 is substantially a negative of a corresponding surface of the 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 joint when the patient specific surface is placed against and aligned with the corresponding surface of the joint, wherein the joint is a shoulder joint of the patient.
2. The surgical instrument system of claim 1 , wherein the portion of the patient-specific surface is a first portion that is substantially a negative of a corresponding subchondral bone surface of the shoulder joint and the patient-specific surface further comprises:
at least a second portion that is substantially a negative of a corresponding cartilage surface of the shoulder joint,
wherein the second portion is configured to align with the cartilage surface when the first portion is placed against and aligned with the subchondral bone surface.
3. The surgical instrument system of claim 2 , wherein the corresponding cartilage surface is a cartilage surface of at least a portion of a proximal humerus of the shoulder joint.
4. The surgical instrument system of claim 1 , wherein the portion of the patient-specific surface is a first portion that is substantially a negative of a corresponding subchondral bone surface of the shoulder joint and the patient-specific surface further comprises:
at least a second portion that is substantially a negative of a corresponding cortical bone surface of the shoulder joint; and
wherein the second portion is configured to align with the cortical bone surface when the first portion is placed against and aligned with the subchondral bone surface.
5. The surgical instrument system of claim 4 , wherein the corresponding subchondral bone surface is a subchondral bone surface of at least a portion of a proximal humerus of the shoulder joint.
6. The surgical instrument system of claim 1 , wherein the portion of the patient-specific surface is a first portion that is substantially a negative of a corresponding cartilage surface of the shoulder joint and the patient-specific surface further comprises:
at least a second portion that is substantially a negative of a corresponding cortical bone surface of the shoulder joint,
wherein the second portion is configured to align with the cortical bone surface when the first portion is placed against and aligned with the cartilage surface.
7. The surgical instrument of claim 6 , wherein the corresponding cartilage surface is a cartilage surface of at least a portion of a proximal humerus.
8. The surgical instrument system of claim 1 , further comprising one or more implant components for repairing the shoulder joint.
