Patient specific glenoid guide

摘要

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.

1. A method of guiding an object toward a glenoid face of a scapula of a patient for implantation of a shoulder prosthetic device, the method comprising:
nesting a first patient-specific surface of a first patient-specific portion of a guide tool to an acromion remote from the glenoid face, the nesting occurring only when the first patient-specific surface of the first patient-specific portion is in a single position relative to the glenoid face; nesting a second patient-specific surface of a second patient-specific portion of the guide tool to the glenoid face, the nesting occurring only when the second patient-specific surface of the second patient-specific portion is in a single position relative to a surface of the portion of the scapula, the second patient-specific portion spaced apart from the first patient-specific portion with a patient-generic portion therebetween, the guide tool configured such that nesting of the second patient-specific portion occurs prior to nesting of the first patient-specific portion; positioning a guide portion of the guide tool on the glenoid face; and cutting the glenoid face with a patient-specific cutting surface of the guide portion.
