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.
1. A glenoid device for preparing a shoulder joint of a patient comprising: a reusable guide holder having a body between an upper surface and a lower surface and a tubular element extending from the upper surface, the tubular element having a bore passing through the tubular element of the guide ho
1. A glenoid device for preparing a shoulder joint of a patient comprising: a reusable guide holder having a body between an upper surface and a lower surface and a tubular element extending from the upper surface, the tubular element having a bore passing through the tubular element of the guide holder and aligned with a bore through the body; anda patient-specific glenoid guide having a body between an upper surface and a lower surface, wherein the lower surface of the patient-specific glenoid guide is a patient-specific surface configured as a negative surface of a glenoid face based on an image of a shoulder joint of a patient reconstructed preoperatively from image scans of the shoulder joint of the patient and wherein the upper surface of the glenoid guide is configured to be coupled to and contact the lower surface of the guide holder, such that the bore of the tubular element and the bore of the body are aligned with a patient-specific bore through the body of the patient-specific glenoid guide and along an alignment axis of the patient-specific glenoid guide corresponding to an axis of the shoulder joint determined according to a pre-operative plan of the patient, the patient-specific bore and the corresponding alignment axis being disposed at an orientation relative to the glenoid face according to a preoperative plan for the patient. 2. The glenoid device of claim 1, wherein the body of the guide holder is plate like and the lower surface is flat. 3. The glenoid device of claim 1, wherein the alignment axis is an anatomic alignment axis of the shoulder joint of the patient. 4. The glenoid device of claim 1, wherein the alignment axis is a reverse alignment axis of the shoulder joint of the patient. 5. The glenoid device of claim 1, wherein the guide holder is coupled to the patient-specific glenoid guide by a plurality of pins received into corresponding holes of the upper surface of the patient-specific glenoid guide. 6. The glenoid device of claim 1, wherein the patient-specific glenoid guide includes a single boss extending from the upper surface at a location indicative of one of anatomic and reverse shoulder arthroplasty use. 7. The glenoid device of claim 6, wherein the guide holder includes first and second windows, the first window marked for anatomic use and the second window marked for reverse use. 8. The glenoid device of claim 7, wherein the single boss is received in one of the first and second windows to provide an indication of anatomic or reverse shoulder arthroplasty. 9. The glenoid device of claim 1, wherein the body of the patient-specific glenoid guide has a three-dimensional shape and size configured to align the bore of the body of the glenoid holder along the patient-specific bore through the body of the patient-specific glenoid guide. 10. The glenoid guide of claim 1, wherein the guide holder includes a handle shaft attached to the upper surface of the body of the guide holder. 11. The glenoid guide of claim 1, wherein the tubular element is oriented at a fixed orientation relative to the lower surface of the body of the guide holder. 12. The glenoid device of claim 1, wherein the patient-specific glenoid guide includes a peripheral portion that engages a corresponding peripheral surface of the glenoid of the patient. 13. The glenoid device of claim 1, wherein the upper surface and the lower surface of the patient-specific glenoid guide are preoperatively designed such that the patient-specific glenoid guide can be coupled to the reusable guide holder and orient the tubular element of the reusable guide holder along the corresponding alignment axis when the lower surface of the patient-specific glenoid guide is positioned against the glenoid face. 14. A glenoid device for preparing a shoulder joint of a patient comprising: a reusable guide holder having a handle shaft and the reusable guide holder defining a bore there through at a fixed orientation relative to the handle shaft; anda patient-specific glenoid guide having a body between an upper surface and a lower surface, wherein the lower surface of the patient-specific glenoid guide is a patient-specific surface configured to nestingly mate and conform to a corresponding surface of a glenoid face of a patient based on an image of a shoulder joint of the patient as reconstructed preoperatively from image scans of the shoulder joint of the patient, the body of the patient-specific glenoid guide defining a bore having a patient-specific orientation between the upper and lower surfaces so that the patient-specific bore is aligned along an alignment axis corresponding to an anatomic or reverse axis of the shoulder joint of the patient determined according to a pre-operative plan of the patient, the body of the patient-specific glenoid guide configured such that the bore of the guide holder and the patient-specific bore of the patient-specific glenoid guide are aligned along the alignment axis when the guide holder and the patient-specific glenoid guide are directly coupled to one another. 15. The glenoid device of claim 14, wherein the reusable guide holder includes a tubular element attached to an upper surface of the guide holder and having a bore aligned with the bore of the guide holder. 16. The glenoid device of claim 14, wherein the guide holder has a substantially flat body between the upper surface and the lower surface. 17. The glenoid device of claim 16, wherein the glenoid holder includes first and second windows marked with designations indicating anatomic and reverse shoulder arthroplasty. 18. The glenoid device of claim 17, wherein the patient-specific glenoid guide includes a boss extending from the upper surface of the body of the patient-specific glenoid guide and configured to be received in one of the first and second windows of the guide holder to indicate anatomic or reverse shoulder arthroplasty. 19. The glenoid device of claim 14, wherein the guide holder is directly coupled to the patient-specific glenoid guide via a plurality of pins received in corresponding holes of the patient-specific glenoid guide. 20. The glenoid device of claim 14, wherein the patient-specific glenoid guide includes a peripheral portion that engages a corresponding peripheral surface of the glenoid of the patient. 21. The glenoid device of claim 14, wherein the lower surface of the patient-specific glenoid guide is shaped and the bore of the patient-specific glenoid guide is oriented between the upper and lower surfaces such that the bore of the patient-specific glenoid guide aligns with the alignment axis of the patient when the lower surface of the patient-specific glenoid guide is mated to the glenoid face, the alignment axis of the patient being based on a preoperative plan for the patient.
