Patient-specific glenoid guides
First Claim
1. An orthopedic device for a shoulder joint of a patient comprising:
- a glenoid guide having an upper surface and a lower surface, wherein the lower surface is a patient-specific surface configured as a negative surface of a glenoid face based on a three-dimensional image of a shoulder joint of a patient reconstructed preoperatively from image scans of the shoulder joint of the patient, the glenoid guide including an anatomic tubular drill guide extending from the upper surface along an anatomic alignment axis configured preoperatively with a patient-specific orientation for guiding a glenoid implant into the glenoid face for anatomic shoulder arthroplasty, the glenoid guide including a reverse tubular drill guide extending from the upper surface along a reverse alignment axis configured preoperatively with a patient-specific orientation for guiding a glenoid baseplate into the glenoid face for reverse shoulder arthroplasty, wherein the reverse alignment axis is tilted inferiorly relative to the anatomic alignment axis.

Abstract
A glenoid guide has an upper surface and a lower surface, wherein the lower surface is a patient-specific surface configured as a negative surface of a glenoid face based on a three-dimensional image of a shoulder joint of a patient reconstructed preoperatively from image scans of the shoulder joint of the patient. The glenoid guide includes an anatomic tubular drill guide extending from the upper surface along an anatomic alignment axis configured preoperatively with a patient-specific orientation and insertion location for guiding a glenoid implant into the glenoid face for anatomic shoulder arthroplasty. The glenoid guide includes a reverse tubular drill guide extending from the upper surface along a reverse alignment axis configured preoperatively with a patient-specific orientation and insertion location for guiding a glenoid baseplate into the glenoid face for reverse shoulder arthroplasty.
