Patient-specific glenoid guide and implants
First Claim
1. A method for forming a mold for use in repairing a defect in a bone, the defect having a surface that defines a volume within the bone, the method comprising:
- receiving imaging data obtained using a medical imaging technique, the imaging data representing the bone and a defect in the bone, the defect including a cavity in the bone;
creating a three-dimensional (3D) model of a mold for an implant based on the imaging data, the mold including a cavity that replicates the volume and shape of the cavity of the defect, the mold further including a first portion having a first surface that matches the surface of the defect defining the volume, and a second portion having a second surface for defining a portion of an articular surface at the location of the defect;
forming the mold based on the 3D model; and
creating a 3D model of a guide based on the imaging data, the guide being configured to position a cutting tool relative to the bone as the cutting tool is used to create a void in the bone, the guide includes a nesting surface configured to engage the surface of the defect defining the volume to position the guide relative to the bone.

Abstract
A method is disclosed for repairing a defect in an anatomical feature, the defect having a surface that defines a volume. The method includes receiving imaging data obtained using a medical imaging technique. The imaging data represents the anatomical feature. In one example, the method further includes creating a three-dimensional (3D) model of a mold for an implant based on the imaging data. The mold includes a cavity that replicates the volume of the defect. In another example, the method further includes creating a 3D model of an implant based on the imaging data. The implant is configured to fill the volume of the defect. In various implementations, the mold, the implant, and/or a replica of the implant are formed based on the 3D model of the mold or the 3D model of the implant. Guides and implants corresponding to the method are also disclosed.

8. A method for forming an implant for use in repairing a defect in a bone, the defect having a surface that defines a volume within the bone, the method comprising:
-
receiving imaging data obtained using a medical imaging technique, the imaging data representing the bone and a defect in the bone, the defect including a cavity in the bone; creating a three-dimensional (3D) model of an implant based on the imaging data, the implant being configured to fill the volume of the cavity of the defect, the implant including a first surface that conforms to the shape of the defect surface that defines the volume of the cavity of the defect and a second surface that forms a portion of an articular surface at the location of the defect; and creating a 3D model of a guide based on the imaging data, the guide being configured to position a cutting tool relative to the bone as the cutting tool is used to create a void in the bone, the guide includes a nesting surface configured to engage the surface of the defect defining the volume to position the guide relative to the bone. - View Dependent Claims (9, 10, 11, 12, 13)
