Patient-specific glenoid guide with a reusable guide holder
First Claim
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; and
a 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.

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.

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; and a 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. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21)
