    摘要： A method of determining an optimal position of a glenoid implant. The method includes identifying a center point of a patient's glenoid fossa based on an image of the patient's glenoid fossa; determining the optimal position of the glenoid implant based on the location of the center point relative to a medial point of the patient's scapula; and selecting orientation of an alignment pin based on the determined optimal glenoid implant position such that the glenoid fossa will be prepared to receive the glenoid implant at the optimal position when the glenoid fossa is prepared with a cutting device or guide coupled to the alignment pin.
