Abstract
Methods and devices are disclosed relating improved articular models, implant components, and related guide tools and procedures. In addition, methods and devices are disclosed relating articular models, implant components, and/or related guide tools and procedures that include one or more features derived from patient-data, for example, images of the patient's joint. The data can be used to create a model for analyzing a patient's joint and to devise and evaluate a course of corrective action. The data also can be used to create patient-adapted implant components and related tools and procedures.
Claims26
A pre-primary articular implant component comprising:
- (a) an outer, joint-facing surface comprising a bearing surface portion;
- and
- (b) an inner, bone-facing surface comprising one or more patient-engineered bone cuts selected and/or designed from patient-specific data.
A method for minimizing resected bone from a single patient in need of an articular implant replacement procedure, the method comprising:
- (a) identifying unwanted tissue from one or more images of the patient's joint;
- (b) identifying a combination of resection cuts and implant component features that remove the unwanted tissue and also provide maximum bone preservation;
- and (c) selecting and/or designing for the patient a combination of resection cuts and implant component features that provide removal of the unwanted tissue and maximum bone preservation.
A method for making an articular implant component for a single patient in need of an articular implant replacement procedure, the method comprising:
- (a) identifying unwanted tissue from one or more images of the patient's joint;
- (b) identifying a combination of resection cuts and implant component features that remove the unwanted tissue and also provide maximum bone preservation;
- and (c) selecting and/or designing a combination of resection cuts and/or implant component features that provide removal of the unwanted tissue and maximum bone preservation.
A femoral implant component comprising:
- (a) a joint-facing surface comprising a bearing surface portion, and (b) a bone-facing surface comprising six or more bone cuts.
A femoral implant component comprising:
- (a) a joint-facing surface comprising a bearing surface portion, and (b) a bone-facing surface comprising a distal bone cut having two or more planar facets or portions that are non-coplanar with each other.
