Patient specific glenoid guide
First Claim
1. A patient-specific guide for guiding an object toward a glenoid face of a scapula of a patient for implantation of a prosthetic device, the guide tool comprising:
- a patient-specific portion having at least one patient-specific surface that is configured to nest and closely conform to a corresponding surface of the glenoid face to position the at least one patient-specific surface at a predetermined position relative to the glenoid face;
at least one tube projecting from the patient-specific portion opposite the at least one patient-specific surface, the at least one tube is configured to act as a guide surface for guiding at least one of a drill bit and a referencing object through to the patient-specific portion;
a member connected to one of the patient-specific portion or the at least one tube; and
a second patient-specific portion connected to the member and configured to engage and mate to a second portion of the scapula other than the glenoid face or a rim of the glenoid face.

Abstract
A patient-specific guide tool for guiding an object toward a glenoid face of a scapula of a patient for implantation of a shoulder prosthetic device is disclosed. The guide tool includes a guide portion that includes a guide surface. The guide surface is configured to guide movement of the object toward the glenoid face. Furthermore, the guide tool includes a patient-specific portion that is operably coupled to the glenoid portion. The patient-specific portion includes at least one patient-specific surface that is three-dimensionally contoured and that is configured to nest and closely conform to a corresponding surface of the scapula to thereby position the guide surface at a predetermined position relative to the glenoid face.

12. A patient-specific guide for guiding an object toward a glenoid face of a scapula of a patient for implantation of a prosthetic device, the guide tool comprising:
-
a patient-specific portion having at least one patient-specific surface that is configured to nest and closely conform to a corresponding surface of the glenoid face to position the at least one patient-specific surface at a predetermined position relative to the glenoid face; at least one of a first tube and a second tube projecting longitudinally from the patient-specific portion opposite the at least one patient-specific surface, the first tube defining a first opening that extends longitudinally along a length of the first tube from an end thereof to the patient-specific portion, the second tube defining a second opening that extends longitudinally along a length of the second tube from an end thereof to the patient-specific portion, the first opening and second opening allowing access for at least one of a drill bit and referencing object to the glenoid face through the patient-specific portion; a member connected to one of the patient-specific portion or the at least one of the first tube and the second tube; and a second patient-specific portion connected to the member and configured to engage and mate to a second portion of the scapula other than the glenoid face or a rim of the glenoid face; wherein the at least one patient-specific surface is configured to nest and closely conform to the corresponding surface of the glenoid face to locate at least one of the first and second openings in a predetermined manner relative to the glenoid face. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. A patient-specific guide for guiding an object toward a glenoid face of a scapula of a patient for implantation of a prosthetic device, the guide tool comprising:
-
a patient-specific portion having at least one patient-specific surface that is configured to nest and closely conform to a corresponding surface of the glenoid face to position the at least one patient-specific surface at a predetermined position relative to the glenoid face; and a first tube and a second tube projecting from the patient-specific portion opposite the at least one patient-specific surface, the first tube is configured to act as a first guide surface for guiding at least one of a drill bit and a referencing object through a first opening to the glenoid face, the second tube is configured to act as a second guide surface for guiding at least one of the drill bit and the referencing object through a second opening to the glenoid face; wherein the at least one patient-specific surface is configured to nest and closely conform to the corresponding surface of the glenoid face to locate the first opening in a predetermined manner relative to the glenoid face for use during a normal shoulder implantation procedure and to locate the second opening in a predetermined manner relative to the glenoid face for use during a reverse shoulder implantation procedure. - View Dependent Claims (20)
