Patient-specific glenoid guides
First Claim
1. A system for a shoulder joint of a patient comprising:
- a glenoid guide comprising;
an upper surface;
a lower surface that is shaped as a patient-specific surface that is configured as a negative surface of at least a portion 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;
a first drill guide extending from the upper surface along a first alignment axis configured preoperatively with a patient-specific orientation and insertion location for guiding a first glenoid implant into the glenoid face;
a second drill guide extending from the upper surface along a second alignment axis configured preoperatively with a patient-specific orientation and location for guiding a second glenoid implant into the glenoid face;
a baseplate implant configured to engage the glenoid face and having a plurality of fixation holes therein; and
a finishing drill guide configured to couple with the baseplate implant, the second drill guide including a plurality of drilling bores that communicate with the fixation holes.

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.
