Abstract
A glenoid device for preparing a shoulder joint of a patient includes a reusable guide holder having a body between an upper surface and a lower surface and a bore passing through the body of the guide holder. The glenoid device also includes a patient-specific glenoid guide having a body with an upper and lower surface. The lower surface of the patient-specific glenoid guide is configured as a negative surface of a glenoid face based on preoperative image scans of the shoulder joint of the patient. The upper face of the patient-specific glenoid guide is configured to be coupled and contact the lower face of the guide holder, such that the bore of the guide holder is aligned along a patient-specific bore through the body of the patient-specific glenoid guide and along a corresponding alignment axis of the patient-specific glenoid guide.

21. A glenoid device for preparing a shoulder joint of a patient comprising:
-
a reusable guide holder comprising a handle shaft; and a patient-specific glenoid guide having a body couplable to the reusable guide holder, the body defining a patient-specific surface configured to nestingly mate and conform to a corresponding portion of a surface of a glenoid face of a patient based on an image of a shoulder joint of the patient as reconstructed preoperatively from a medical image of the shoulder joint of the patient; and a tubular element connected to the body, the tubular element defining a bore having a patient-specific orientation aligned along an alignment axis of the patient determined according to a pre-operative plan of the patient. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31)

32. A glenoid device for preparing a shoulder joint of a patient comprising:
-
a patient-specific glenoid guide having a patient-specific surface configured to nestingly mate and conform to a corresponding surface of an anatomic landmark of a glenoid of a patient, the patient-specific surface shaped based on a three-dimensional model of a shoulder joint of the patient as reconstructed from preoperative imaging of the shoulder joint of the patient; wherein the patient-specific glenoid guide defines a bore having a patient-specific orientation relative to the patient-specific surface so that the bore is aligned along an alignment axis of the shoulder joint of the patient determined according to a pre-operative plan of the patient; and a reusable handle shaft connectable to the patient-specific glenoid guide. - View Dependent Claims (33, 34, 35, 36, 37, 38)

39. A glenoid device comprising:
-
a patient-specific glenoid guide for referencing a plurality of landmarks on a glenoid to orient the glenoid guide in a predetermined orientation according to a preoperative plan for a specific patient; an alignment bore extending through a portion of the patient-specific glenoid guide; and a tubular element connected to the patient-specific glenoid guide at the alignment bore. - View Dependent Claims (40, 41, 42, 43, 44, 45, 46, 47)
